|Primary Data - one of the
best known enterprise software companies in 2016-2017 - emerges from stealth|
November 19, 2014 - Primary Data -
the most ambitious storage software startup I have ever encountered - today
emerged from stealth mode - with 2 announcements.

- 1st announcement
that Steve Wozniak
has joined the company as Chief Scientist.
Wozniak who cofounded
1976 - elevated the general
visibility of fledgling Fusion-io
when he joined that company in the Chief Scientist role
The impact of this was assessed and captured in a
2011 blog by Woody Hutsell
- who at that time was working at erstwhile enterprise SSD competitor -
TMS. Woody wrote at
that time (2011)...
"I used Google trends data to see if there was
an inflection point for Fusion-IO and I found it. The inflection point was their
hiring of Steve Wozniak. What a brilliant publicity move... I spent a lot of
time trying to figure out how to create a similar event at TMS. I thought if we
could hire Elvis we would have a chance."

"With Woz on the team along with Lance and
we now have the band back together, and Im amped to be reunited at Primary
Enmotus FuzeDrive software - now available
November 4, 2014 - Micro-tiering within the server box - between the lowest
possible latency persistent memory (such as
flash backed DRAM
DIMMs from Viking),
then up a level to SATA
SSDs and finally to hard
drives - gives users materially different performance and cost
characteristics to merely caching between those devices when they are used in
a hybrid storage
That's the message behind the
about the general availability of the company's
server (SSD software)
for Windows and Linux - in which (unlike simple server based cache based
solutions) - FuzeDrive treats the SSD as primary storage and so "all
reads and writes to the hot data occur at full SSD speeds".
SSDs are becoming
in some cases" said Marshall
Lee, CTO and co-founder of Enmotus. "As a result, newer classes of
storage devices continue to appear that can take advantage of higher performance
busses inside servers, NVDIMMs
being a great example."
McObject expands reach of in memory database for serious embedded
Editor:- October 28, 2014 - First 2, then 3 and
finally - 4 interesting things caught my eye in
news about version 6.0 of
eXtremeDB - an in-memory database system from McObject
- Data compression. This release adds data compression for both in-memory
and on-disk databases. Once upon a time compression was a value add feature in
some products - but now in the SSD age when compression is almost latency free
- it has become a must-have on the feature list - especially for embedded
- Avionics platform support. This upgrade adds compatibility with
River Systems' VxWorks 653 COTS platform for delivering safety-critical,
integrated modular avionics applications.
- More flexible transaction scheduling. Applications using eXtremeDB's
multiple-user, single-writer transaction manager can override the default FIFO
scheduling policy within priority levels to favor either read-only or read-write
""Demand for distributed
query processing cuts across market segments, but is especially relevant to the
automation and control field, where eXtremeDB is historically strong"
said McObject CEO and co-founder Steve Graves.
- Distributed query processing support. eXtremeDB partitions a database and
distributes query processing across multiple servers, CPUs and/or CPU cores -
which can accelerate performance.

Efficiency is important for web scale users - says Coho
October 9, 2014 -
as a file system - a web scale case study - a new blog by Andy Warfield , cofounder
and CTO - Coho Data

authoritative approach taken in Andy's systematic analysis - as for the object
of his discussion (Facebook's storage architecture).
It reveals useful
insights into the architectural thinking and value judgments of Coho's
technology - and is not simply another retelling of the Facebook infrastructure

enterprise ideas related to
dark matter users.
All of which makes it hard to pick out any single quote. But here are 2.
- re -
match between enterprise products and user needs
says - "In the past, enterprise hardware has had a pretty hands-off
relationship with the vendor that sells it and the development team that builds
it once it's been sold. The result is that systems evolve slowly, and must be
built for the general case, with little understanding of the actual workloads
that run on them."
There are many more I
could have chosen. ...

- re efficiency
Warfield says - "Efficiency is important. As a rough approximation, a
server in your datacenter costs as much to power and cool over 3 years as it
does to buy up front. It is important to get every ounce of utility that you
can out of it while it is in production."

persistent enterprise memory - says SanDisk
Editor:- October 3,
2014 - New enterprise software abstractions are needed in order to
those unruly developments in flash,
And laying the
framework for those ideas - along with some practical suggestions for where
applicable solutions might be coming from - is the theme of a recent blog -
Emergence of Software-Defined Memory - written by Nisha Talagala,
Fellow at SanDisk
- who (among other things) says:-
"We're seeing excitement build
for a new class of memory:- persistent memory - which has the persistence
capabilities of storage and access performance similar to memory.
"Given this richness of media technologies, we now have the
ability to create systems and data center solutions which combine a variety of
memory types to accelerate applications, reduce power, improve server
consolidation, and more.
"We believe these trends will drive a
new set of software abstractions for these systems which will emerge as
software-defined memory a software driven approach to optimizing memory
of all types in the data center." ...read

- discusses Microsoft's D-Series SSD-aware VMs - and places this in the context
of other products from well known sources.
The blog's author - Janakiram MSV says "One
important aspect of SSD based VMs on Azure is that they are not persistent. Data
stored on these volumes cannot survive the crash or termination of virtual
machines. This is different from both Amazon EC2 and Google Compute Engine,
which offer persistent SSDs. On Azure, customers have to ensure that the data
stored on the SSD disks is constantly backed up to Azure blob storage or other
HGST announces 2nd generation clustering software for FlashMAX
Editor:- September 9, 2014 - HGST today
a new improved version of the
clustering capability previously available in the
PCIe SSD product line
acquired last year from Virident.
allows clustering of up to 128 servers and 16 PCIe storage devices to deliver
one or more shared volumes of high performance flash storage with a total usable
capacity of more than 38TB.
HGST says its Virident HA provides a "high-throughput,
low-latency synchronous replication across servers for data residing on FlashMAX
PCIe devices. If the primary server fails, the secondary server can
automatically start a standby copy of your application using the secondary
replica of the data."
For more details see -
Virident Software 2.0 (pdf)
Editor's comments:- This
capability had already been demonstrated last year - and
ESG reported on the
technology in January
But at that time - the clustering product called vShare -
was restricted to a small number of servers - and the data access fabric was
restricted to Infiniband
With the rev 2.0 software - the number of connected devices has
increased - and users also have the lower cost option of using

of storage hardware. In our view, storage is not a hardware problem, but that
hardware is the problem and to solve that you need intelligent software that

SanDisk extends the reach of its SSD software platform
July 8, 2014 - 2 weeks ago
a new enterprise software product -
ZetaScale - designed
to support large inmemory intensice applications.
I delayed writing
about it at the time - until I learned more. But now I think it could be one of
the most significant SSD software products launched in 2014 - because of the
freedom it will give big memory customers (in the next 2-3 years) about how
they navigate their tactical choices of populating their apps servers with
low latency flash SSD hardware.
what is ZetaScale?
says - "ZetaScale software's highly parallelized code supports high
throughput for flash I/O, even for small objects, and optimizes the use of CPU
cores, DRAM, and flash to maximize application throughput. Applications that
have been flash-optimized through the use of ZetaScale can achieve performance
levels close to in-memory DRAM performance."
ZetaScale is SSD
agnostic. "ZetaScale is compatible with any brand of PCIe, SAS, SATA, DIMM
or NVMe connected flash storage device, providing customers the ability to
choose, avoiding hardware vendor lock-in."
I was curious to see
how this new product - which is a toolkit for deploying flash with tiering to
DRAM as a new memory type - fitted in with other products - from SanDisk and
from other vendors which also operate in this "flash as a big
memoryalternative to DRAM" application space .
So I asked
SanDisk some questions - and got some interesting answers.
- Where does the ZetaScale product come from?
ZetaScale builds upon our
acquisition technology for additional use cases and flash deployment models.
ZetaScale allows any developer to better tune their applications for
flash-based environments, no matter which vendors hardware or interface is being
leveraged. Thus, ZetaScale represents a major step forward in our vision of the
flash-transformed data centerempowering software developers to scale and
enhance their applications to meet today's big data and real-time analytics
demands, while lowering TCO.
- How much commonality is there between ZetaScale and FlashSoft product
ZetaScale and FlashSoft software are complementary and
FlashSoft provides direct-attached flash-based
caching for NAS and SAN devices, with the goal of improving performance for
unmodified applications running on a server.
software provides a flash and multi-core optimization library that applications
can integrate to allow them to achieve 3x times the performance
improvement from flash alone.
Both ZetaScale and FlashSoft software
provide their benefits in bare metal and virtualized environments
- Does ZetaScale support ULLtraDIMM?
Yes. The software is compatible with any brand of PCIe, SAS,
SATA, DIMM or NVMe connected flash device, enabling users to avoid vendor
lock-in. However, the software does not get embedded into any SSD.
Editor's comments:- overall I'd have to rate SanDisk's -
ZetaScale as one of the most significant SSD software products launched in 2014.
- How would ZetaScale fit into a future SanDisk product line which also
SanDisk cannot comment on open M&A activity. As usual, all
planning surrounding the product portfolio and roadmap will begin following the
close of the acquisition.
From a technical point of view - it's a toolkit which will enable
architects of SSD apps servers with very large in memory databases to
decouple themselves fromdeep dives into specific low latency SSD products.
Instead of gambling on whether they should exploit particular features which
come with particular low latency SSDs - they can instead use ZetaScale as the
lowest level of flash which their apps talk to. And that will change markets.
although SanDisk didn't want to comment on how this would be positioned against
Fusion-io's VSL - it's
undeniable that in some applications it does compete today.
wouldn't be surprised to see - a year after the acquisition (if it goes ahead)
ZetaScale could be useful as a way of introducing new customers to the
ioMemory hardware environment - without those customers having to make a hard
commitment to the rest of Fusion-io's software.
And - looking at the
SSD market - it also means that SanDisk software might be a safer standard
for future customers of any DDR4 or HMC SSDs which might emerge from competitor
Micron which - unlike
SanDisk - hasn't demonstrated yet any strong ambitions in the
SSD software platform
What do you get when you add Fusion-io's software to SanDisk?
June 17, 2014 - I discussed some of the possibilities in my blog yesterday in
SSD news - following the
announcement that SanDisk
has agreed to acquire Fusion-io.

Decloaking hidden segments in the enterprise

hidden segments in the enterprise for rackmount SSDs
Some of the
world's leading SSD marketers have confided in me they know from
their own customer anecdotes that there are many segments for enterprise
flash arrays which aren't listed or even hinted at in standard models of
the enterprise market.
Many of these missing market segments don't
even have names.
The glut of new flavors in SSD software - mostly
boldly promising new architectures but sometimes with a better plea
bargain for legacy - is one of the biggest segment multiplying factors.
OCZ betas the next incremental release of its SQL accelerator

Fusion-io demonstrates life and capacity amplification effects
of combining 2 software ingredients
Editor:- April 2, 2014 - In a
demonstration this week Fusion-io showed the
combined advantages of using NVM compression in conjunction with its Atomic
Writes APIs in SkySQL environments. The results indicate that:-
- 2x as much data can be stored on the same flash media - while
giving similar performance and latency to the uncompressed case with legacy
comments:- compression has been used as a secret invisible
helper inside enterprise flash SSD systems (and as a way to speed up
performance and housekeeping functions such as garbage collection) starting in
2007 with MFT
flash management software from
- using compression and the new APIs - reduces write traffic and improves
endurance limited operating life by a factor of 4x
2009 onwards -
invisible compression speedup and
boosting became widely adopted in the industry - as they were both intrinsic
parts of every SSD
controller shipped by SandForce.
WhipTail was the first
enterprise SSD array vendor I knew of to offer inline time compression as
an explicit feature which users could turn on or off - to increase usable
virtual capacit. That was in
- and James
Candelaria (who at that time was WhipTail's CTO) mentioned this as an
attribute in his
for StorageSearch.com readers in September 2010.
However, in a later
conversation (January 2012) with Cameron Pforr
(who at that time was WhipTail's President and CFO) - Cameron told me they
were no longer emphasizing compression because it led to latencies which were
too long to be competitive - and instead they were focusing on performance.
Since those days many leading SSD array makers have used compression
to offer tactical advantages in their products - particularly in cost sensitive
markets like iSCSI. And
compression and more efficient software are just some of many ingredients I
identified in last year's article
thinking inside the SSD box.
To sum up - Fusion-io's
demonstration this week simply confirms what anyone who knows their product line
well would have already expected.

Maxta joins the elite set of enterprise contenders who are
vying to own the next generation SSD-centric platform
November 13, 2013 - This week Maxta completed its
staged emergence from stealth mode and
its first product - the Maxta Storage
Platform - a hypervisor-agnostic software platform for repurposing arrays
of standard servers (populated with cheap standard
SATA SSDs and
hard drives) into
scalable enterprise class apps servers in which the global CPU and storage
assets become available as an easily managed meta resource with optimized
performance, cost and resilience.
Editor's comments:- I spoke
last week to Yoram
Novick about this new product, his company and what customers have been
doing with it.
Before you dip into my bullet points below - here's a
header note of orientation.
We've all seen new companies launching
SSD software and pitching for the enterprise with products which are little
more than spruced up versions of "hello SSD world!"
year later - some essential compatibility features get added, and later still
some degree of better or worse
It didn't used to matter much if everything wasn't in place at the start - or
if these new companies didn't have sustainable business plans - because there
was an appetite for acquiring
From my perspective I'd say that many companies have
regarded the launch of their SSD software is simply an invitation to attract
users who could provide the market knowledge they needed to flesh out the
In these important respects Maxta is different because:-
prior to this week's product launch they've already had a group of 10 or so
advanced customers in different industries who have been using the product and
also the enterprise features - like manage-ability, scalability, resilience and
data integrity are already in the product today.
Maxta's technology and
business architects have done enterprise storage software before - as you can
see from their linkedin
bios. Yoram told me that he and
Amar Rao (Maxta's VP of
Business Development ) used to compete with each other in earlier storage
startups and the companies which had acquired them.
So it soon became
clear to me in the details I saw and asked about (not all of which are listed
here) that a lot of careful planning and up front thinking and problem solving
has already guided the "launch".
Here's some of what I
- market scope
MxSP is the software glue for enabling easily managed
SSD enhanced storage
pools in VM environments which scale from the ROBO upto
base level configuration which provides HA features starts as low as 3 nodes.
This is attractive for enterprises with remote offices because it's a small
footprint. But it's also attractive from a running cost point of view too -
Yoram said because of the special low price point for associated software.
has a customer who started with these 3 node configurations for remote offices
but liked them so much that their bigger arrays are now built mostly from
arrays of 3 too.
- the problem it solves
The evolution of enterprise CPU and storage
resources have followed different tracks in the past decade - leaving users in
the position today where it's easy and economic to deploy more CPUs but
relatively awkward, expensive or error prone to map these CPU resources into
virtual storage which scales with the same ease and which takes advantage of
the low cost and high performance of commodity enterprise SSDs.
- the storage pool
Maxta's architecture aggregates the SSDs and HDDs
in the server pool into a single globally accessible, fault tolerant SSD
accelerated virtual storage pool.
Within Maxta's software - all the
SSDs are collected together as 1 super SSD resource and another big resource
is created from the HDDs.
Internally Maxta's software knows that SATA
SSDs and SATA HDDs have different personalities for example:-
- HDDs have low cost per unit of capacity but slow random read latency
- SSDs have fast random read, and fast sequential write
every node in the array has to have an SSD or HDD inside but it's not sensible
to have a system which doesn't have any SSDs at all.
- fault tolerance, data integrity, VM snapshots, cloning etc
they're all in the product now.
- software? - it's a virtual world view
Everything about MxSP is
virtual. And it doesn't require new management tools. The operational aspects
will clarify in customer case studies and white papers.
- Maxta's business plan
I told Yoram how disillusioned I had become
about the sustainability and viability of new storage software companies -
given my experience of having tracked over 1,000 storage companies and
terminating the list of
gone-away and acquired companies in a single decade at the 500 company
level. (That's before I started the gone-away SSD companies list BTW - which is
well on its way to 100.)
Jaundiced by that experience it seems to me
that over 95% of storage software startups don't have much of a clue about how
to translate their IP assets into any sustainable business value and are mostly
founded at the outset with the fervent desire that before the VC and IPO
money run out - they will get acquired. So I asked him if Maxta would be any
different to that?
Yoram told me some of what Maxta has been doing in
laying the foundations for growing the business to become a significant storage
platform (in his words) a significant software company like Microsoft or
I won't say more here because this is too long already -
despite having not even mentioned most of the notes I made during our
Looking back on this nearly a week later (and having seen
some of their documents before) I'm left with the impression that maybe indeed
Yoram is right and his company could become not only one of the rare storage
software companies which are sustainable as a business. But going further than
that - maybe too it has the makings of a company which could be one of the
five to ten companies which will dominate the SSD software platform market of
Who are the other contenders?
I've given you
lists before - but this list is evolving because 4 of the 10 companies were
still in stealth mode last time I did that.
If you're interested in
the SSD enhanced storage platform idea (and who wouldn't be) then another good
place to look is the list of competitors which I've compiled in
Maxta's profile page.

Stating the design
principles of this product - Frank Denneman says - "Data loss needs to be
avoided at all times, therefore the FVP platform is designed from the ground up
to provide data consistency and availability. By replicating write data to
neighboring flash devices data loss caused by host or component failure is
prevented. Due to the clustered nature of the platform FVP is capable to keep
the state between the write data on the source and replica hosts consistent and
reduce the required space to a minimum without taxing the network connection too

EMC indicated that
ScaleIO's software - which emulates the capabilities of virtual SAN style

Software - a new reason to reconsider Intel's server SSDs
February 13, 2013 - Intel
that in the next 30 days it will ship a Linux version of the SSD caching
software - based on IP from its acquisition of
NEVEX last August. The
products have been rebranded as
CAS (Cache Acceleration Software).
Editor's comments:- I
would categorize Intel's current generation of enterprise SSD solutions
(which includes the same old indifferent SSDs working with the new CAS software)
as being in the medium to fast-enough performance range.
customers might be end users who have never used SSD acceleration before - or
users with apps which don't need the higher speeds offered by competing SSD
bundled drive / module packages from
OCZ - and customers who
don't want to do their caching via dedicated rackmount based products from
the dozens of other vendors listed in the
SSD ASAPs directory.
market segment addressed by these new Intel products is the early
majority of enterprise SSD adopters - who will be reassured by the
perceived safety of buying into the dangerous world of solid state storage
acceleration from a value based brand.
I spoke about the new CAS
software to Intel product manager Andrew Flint
who cofounded NEVEX and I
learned some useful things about the product.
The first question I
asked was - how many PCIe SSDs can the CAS product support in a single server?
And were there any graphs showing how performance drops off or is maintained
when you do that.
The answer was - this info isn't publicly available
right now. Although it may be in the future.
That's when I concluded
that Intel CAS (married to current generation Intel SSDs) isn't a fast
product - and is not in the kind of performance league where a user would
seriously worry about this type of
Intel's ideal end-user customers right now for CAS are
people who have been using no SSD acceleration at all coupled with hard drive
arrays. That performance
silo could change - with faster Intel SSDs in the future - and isn't due
to limiting characteristics in the software.
I asked - Does it support
3rd party SSDs?
I was told - the standard release only supports Intel
SSDs. But there's nothing in principle to prevent it being used with other SSDs
using the open source release of the software.
The product is a read
cache. I was told that it makes very good use of whatever RAM is in the server
to optimize both read and write performance. However, my view is that as Intel
SSDs aren't fast - this is somewhat academic.
I asked about the time
constants which are analyzed by the caching software - and learned that -
depending on the app - the data usage period which is analyzed goes up to days.
(Generally in this type of product longer is better - and when you go up from
milli-seconds and seconds to minutes, hours and days - you have the potential to
get better caching results.)
I learned that Intel CAS isn't written
around the data structure or interface - and is hardware agnostic. Users can
tell the software which apps they want to cache - via a control panel. This is
very useful in environments where a single server is running a mix of apps -
some of which are critical (in performance needs) while others are not.
asked - does the CAS have to have advance knowledge of the app? - Is it
optimized for a preset list of apps?
I was told - No. It will work
just as well for - what I called - dark matter software- which might be a
proprietary app which no one else knew about.
I asked if Intel collects
stats from the general population of installed servers which use the software? -
in order to improve tuning algorithms...
I was told - No. The
optimizations (data eviction probability rates) are done based on what is
learned on the customer's own server and private data - and the factory shipped
software. There isn't a wider intelligence learning or gathering or snooping
I learned that a special feature of this Intel CAS release
is the ability to share cache resources with a remote SSD. The data stays hot
and doesn't have to be recreated when different virtual machines are accessing
this type of resource.
Overall I came away with a good impression of
the CAS software and how well the NEVEX technology idea has been assimilated
into Intel's SSD business.
It will undoubtedly help Intel sell more
SSDs to people who have never used enterprise SSDs before - and maybe also to
people with low end apps who have used SSD acceleration before but whose
first choice of SSDs wouldn't otherwise have been Intel.
aligning database block sizes with SSDs
February 5, 2013 - I was only saying to someone yesterday that I've had
emails from readers who are designing
software for SSDs who
- having researched the subject of
flash etc - then spent
too much time over-worrying about internal SSD hardware details that they
really shouldn't be worrying about - because by the time they learn about it -
that type of hardware issue is ancient history.
By a curious
coincidence today I came across a recent blog by Chas. Dye at Pure Storage
DON'T Fiddle with Your Database Block Size! - which also warns about this
Chas says - "At Pure Storage, we believe that a factor
that should never influence the block size decision is your storage subsystem."
comments:- I'd certainly agree that trying to slavishly make your data
structures look like something you've read about which might be inside an
SSD controller is
probably a waste of time - because unless you know the SSD designer you don't
really know what's going on - and the abstraction you read about in some web

in memory database is even better with FIO's flash SSDs
November 19, 2012 - McObject
announced that it has run
benchmarks of its (intrinsically
designed for) in-memory database systems software - with transaction logging
enabled - on a number of different devices - and in particular Fusion-io's ioDrive
Editor's comments:- In a paper published 3 years ago
- In-Memory Database Systems:
Myths & Facts - McObject said that fast flash SSDs used as the
storage hot spot for traditional database software could never get performance
as good as their own in-memory solution running in DRAM with legacy hard drive
array bulk storage - and various remarks in that paper sent out a strong
anti-SSD message which the company is in effect correcting today.
McObject is now saying - is that by using a fast low latency SSD for the "performance
draining" transaction log - you can get even greater speedups. There
are other benefits too - which arise from the efficiency of their small
footprint database - which means that a software product - which was originally
designed for the DRAM-HDD world - is a good fit in the flash SSD world too - if
you have the right scale of data and the right SSD.
McObject's Marketing Director Ted
Kenney emailed me to clarify a couple of points about their product
and my interpretation of their business thinking. Here's some of what he said.
would point out one thing about your blog post, just to clarify from McObject's
point of view.
You mention the Myths & Facts white paper, specifically where we
argue (Myth 3, I believe) that an IMDS will always be faster than an on-disk
DBMS that uses an SSD to store records.
Keep in mind that that
paper's comparison does not touch on transaction logging. At least, transaction
logging is not mentioned; the assumption (our assumption, in writing it) is that
the comparison is between a "pure" IMDS (all data kept in main memory
and nothing stored to persistent media), and an on-disk DBMS that stores records
on a SSD. Our conclusion was that while the DBMS storing to SSD is likely faster
than a DBMS storing to HDD, it still can't touch the performance of a pure IMDS.
In contrast, our recent comparison (the subject of the press
release I sent you) is focused differently: it presumes that the user wants data
durability and recoverability. That rules out use of the pure IMDS (because RAM
storage is volatile), so we instead look at solutions that deliver
recoverability/durability, specifically an on-disk DBMS storing records to
persistent media vs. an IMDS with transaction logging (let's call that IMDS+TL).
Then for the IMDS+TL we measure performance using different storage devices:
HDD, SSD and ioDrive.
The result: an IMDS+TL storing its log on HDD beats the performance
of a DBMS storing records to HDD (by about 3x). If you then "upgrade"
the device on which the IMDS+TL stores its transaction log, the performance
difference (compared to DBMS+HDD) is even greater (as much as 15x when
using the ioDrive). But the recent round of testing did not look at
the "pure" IMDS performance. If it had, the pure IMDS would have beat
the IMDS+TL using any of the devices to store its transaction log.
We hadn't considered that our message in the earlier white paper was "anti-SSD"
or that we were now correcting that message. Instead, we'd say that the earlier
paper looked at a scenario in whichperformance is the highest goal (the
only goal mentioned, anyway) whereas the new tests focused on performance, with
durability/recoverability as an additional requirement.
comment - "It seems that a software product which was originally
designed for the DRAM-HDD world is a good fit in the flash SSD world, too
if you have the right scale of data and the right SSD." - Actually
eXtremeDB was designed for the DRAM world initially (in-memory only). When we
later added support for persistent storage (first with transaction logging,
later with optional persistent storage for selected record types) we were (and
still are) agnostic: eXtremeDB does not recognize or care about the type of
persistent media used.
Again thanks for taking the time to
look at our news and at our various statements vis-à-vis flash, storage
and performance. It sounds like you understand our technology and the issues
involved. I just wanted to point out that the white paper's discussion, and this
recent press release, take slight different perspectives on what the
developer/end-user is trying to accomplish.
OCZ's new VXL software release includes fault tolerant support
for arrays of PCIe SSDs
Editor:- October 23, 2012 - OCZ today
a new version (1.2 ) of its
cache and virtualization software - which provides high availability,
synchonous replication and enhanced VM performance across arrays of the
company's Z-Drive R4 PCIe
The company says this assures that host-based flash is
treated as a continuously available storage resource across virtualized clusters
and yields no data loss and no VM downtime even during complete server
"By combining the power of storage virtualization and
PCIe flash caching, and by working centrally with the hypervisor rather than
with each local VM, we have developed a solution that takes full advantage of
flash without losing any of the benefits associated with virtualization,"
said Dr. Allon Cohen,
VP of Software and Solutions, OCZ. "VXL's ability to transparently
distribute flash resources across virtualized environments provides IT
professionals with a simple to implement solution..."
in the SSD software golf challenge who's got a similar handicap
Editor:- October 2, 2012 - last week I was asked
by a reader (who didn't want to be named here) if I could suggest any
companies which have SSD software as powerful and far reaching as that of Fusion-io.
thought it would be much too simplistic to answer with a list of names taken
out of context - so instead I said there are several different levels at
which you can view and analyze this:-
- communicating intelligence between the API and raw flash level
- working between different storage systems and software components (caching,
tiering, virtualization, data protection etc)
After using a lot more words in my email than I've
used here - the end result was a reply to my reader with a list of companies
which you wouldn't be too surprised to see if you looked at the list of top
enterprise SSD companies and correlated that with who's acquired or developed
their own software. The list ran something like this:-
- working in different markets -
consumer? - you ask - I thought we were talking about Fusion-io?
mentioned a few years ago Fusion-io's software is applicable to
It's simply a commercial decision not to pursue that avenue in the current
unprofitable state of the consumer market. But in the long term it's one of the
reasons that the company is rated as being so valuable - because its technology
can span solid state storage from the level of Ultrabooks (with PCIe inside)
(acquired by SanDisk) -
have the makings of a serious industry platform.
- GridIron -
probably has the most sophisticated
SSD ASAP software in
the industry. (In my email I said - shame it's tied to their hardware -
an SSD HDD hybrid box. But this week - that has changed. See the notes below
for more about this.)
between the hardware layers to optimize the system within enterprise racks and
arrays - the ability to hop in with intelligence gained from another level to
tweak performance and reliability - is a genuine efficiency asset.
- SANRAD (acquired by
OCZ) is also a contender.
- Virident -
have several layers of intelligence in their PCIe SSD software. They don't like
to talk too much about the details. But it's one of the things which makes
their offering stronger than many others.
- Nimbus - started
out using a standard SSD controller in their 2.5" SAS arrays - but have
added some firmware level access points which they leverage from higher levels
And in the consumer software space I suggested:-
- Skyera - is
probably the hottest example of this. They dive in at many levels to increase
efficiency of the way they use flash.
The only real surprise in the list above to
regular readers - might be GridIron - which because they haven't been a true
pure SSD company (their main product is hybrid SSD and HDD boxes) don't get so
many mentions on these SSD pages.
- EasyCo - the very
first enterprise SSD software company which was bumped aside by the
technology wave - has found a new market opening selling their
and performance enhancing software to makers of cheap flash storage for phones
and consumer devices. It's no longer world beating IP - but it has its uses.
(And maybe attractive for future patent trolls.)
Anyway - I was reminded about the
above email exchange when I saw GridIron's
release in my email this morning regarding their
GT-1500 Data Accelerator Appliance - a 2U 12TB SSD ASAP - which can
accelerate upto 120TB of back end storage.
In one way this can be
regarded as an extrapolation of
- which was launched 3 years ago. But the difference is in the detail and
sophistication of the hotspot algorithms - which GridIron describe as "multi-zone
behavior profiling (pdf)"
GridIron have a new (to me)
marketing tagline - "Tier 0 Performance at Tier 2 Pricing" -
I don't like SSD
tiers myself - I prefer the idea of
application silos. But GridIron's summary of what they do is better than
Going back to the original question at the start of today's

areas the answer is - Yes.

August 15, 2012 - Do you remember FlashSoft?
Many of you still do. It was one of the
SSD software companies
before it got acquired 6 months ago by SanDisk.
of the tips in the
Guide to Enterprise SSDs - is that when it comes to SSDs - rules are
made to be broken.
And earlier this week I learned this can
apply to my own gut feel rules of thumb too. The unwritten rule being that
semiconductor companies generally make a mess of enterprise software and are not
so hot at understanding the enterprise SSD market either.
I had expected that FlashSoft would disappear into SanDisk - and would get
smothered by a marketing organization which had many times before demonstrated
its lack of awareness of the fundamentals of good enterprise SSD marketing. And
that was the tone of my parting message to the founders along with a few words
of congratulations as they disappeared into the new SNDK afterlife. I never
expected to hear from them again.
So the first thing I asked Rich Petersen -
(former VP of Marketing at FlashSoft and now Director, Marketing Management at
SanDisk) a few days ago was - how are they doing as part of a chip company?
What are they doing with the FlashSoft brand? How do they plan to develop the
enterprise SSD business? etc.
One of the things that Rich had wanted
to talk about was the release of new support in their caching software for
We spent a lot of time talking about that too - and had a big discussion about
the role of SSD software - not only as a business tool - but in effect as a new
way of virtualizing and looking at enterprise SSDs and how they can fit into
architecture models. (My view is that a powerful SSD suite - if it becomes
widely used - can be as significant to the SSD market - as a new interface
or form factor.)
We covered enough ground to write several long
articles. I'm not going to do that today - because I'm supposed to be on
vacation and sitting out in the garden by my pool.
So you should
regard this as the really really short version - and a placeholder for much
more detail which I will return to later.
FlashSoft - or the
enterprise SSD software part of SanDisk (or whatever else you may want to call
it) is today operating in a business mode which is like what you would expect
from a best of breed enterprise SSD systems company. They talk to end users like
they've always done. They learn to change important aspects of how the products
work and are sold because of feedback from end users - and not because they've
read that something is a good idea in a
There are some surprising consequences of this at the
technical and business level.
Chief among those surprises for me is
that FlashSoft says it will still support other brands of SSDs. Rich
explained this was just a pragmatic business decision. Big users told them they
like FlashSoft - but they already use or might want to use non-SanDisk SSDs.
These users are only going to standardize on one SSD software platform. They
don't want to learn 2 different ways of doing the same thing.
other hand an advantage of having access to an enterprise SSD maker is that if a
big user needs some expensive hardware on which to evaluate the benefits of
their software - then it's easier on the marketing budget to get some SanDisk
SSDs to do this.
FlashSoft's visibility into what enterprise end users
really do - and the suprising preferences they have - which are driven by
customer business optimizations rather than simplistic technical extrapolations
- also means that - like rackmount SSD companies - FlashSoft learns valuable
market lessons which can be reapplied to optimize designs in future SanDisk

its new ION software
- which is a toolkit for bulding your own network compatible
SSD rack by
adding some Fusion-io SSD cards and their new software to any leading server.
The concept isn't entirely new - because oems have been doing this
with various different brands of
PCIe SSDs for years
and this is a well
established alternative market segment for PCIe SSDs. What is new - is
that it makes the whole thing much easier.
Fusion-io says this new
software product "delivers breakthrough performance over
iSCSI using standard
protocols." (1 million random IOPs (4kB), 6GB/s throughput and 60
microseconds latency in a 1U rack.)

Going back to SSD software...
Microsystems created and leveraged the phrase -
Network is the Computer.
I have long thought an apt
reinterpretation of that in this decade is "the SSD is the computer"
- or maybe the "SSD software is the computer" - because the ultimate
characteristics of fast computers are determined more by the SSD architecture
which is installed - than by the same old CPU chips.

Pappas:- It varies by workload, but typically it takes about 15
minutes for the cache to warm to reach peak efficiency.

AutoCache will only cache reads, but by virtue of relieving the backend
datastore from read traffic, we have actually seen overall write performance
improvements as well. This effect is also dependent on the workload.

June 6, 2012 - STEC
the general availability of the company's

Software for Linux and Windows environments with pricing starting from $295

STEC says its SSD
cache software can used with any vendor's
In addition, a Linux version of EnhanceIO SSD Cache Software, based on
caching module, will be made available under a general public license
"As one of the original architects of Flashcache, I'm extremely
pleased to see this technology being enhanced and supported by STEC in their
EnhanceIO software," said Mohan Srinivasan, software engineer at
Facebook. "Flashcache has proven to be an invaluable tool for accelerating
application performance at Facebook."
Users can choose from a selection of caching schemes and block sizes
to suit their preference and SSD's capabilities. STEC stores the metadata for
the cache in system DRAM rather than in the SSD. The DRAM required for the
cache is 0.1% of the cache size so a terabyte of SSD cache requires about
1GB of DRAM support. Product support tools include a profiler which can collect
user data and suggest the best policy option parameters for the cache setup.

One of the ironies of legacy systems software running in
flash systems is the way that the data weaves through layers of fossilized
unreality where emulation is stacked on emulation - and hardwired into
the software and data flow logic are the remembered
once-deemed-to-be-efficient solutions to data flow control problems whose
origins are now almost forgotten.
So the SSD emulates a hard drive.
And the hard drive emulates memory.
And it gets worse.

happen behind the scenes makes it appear more like a bunch of courtiers in a

way to save time (improve latency) is to say - what if instead of just
speeding up all the tangled processes of emulating a hard drive emulating
memory and worrying about all the old fossilized limits of packet sizes and
flow control in drives and interface cards which no longer exist except in
museums but which have been preserved in legacy software - we instead
make an effort to write some new software which knows it's operating in a flash
world and doesn't have to recite old HDD spells to charm the data?
what-if the Princess knows where the shoe room is - and rather than wait -
she's going to get the shoes for herself?

pin down to a single year. For example the transition in the enterprise SSD
market from RAM
to 98% flash - which took 8 years.
Although it's easy to
recognize the start of new technology changes - it's harder to be so precise
about big market shifts - because those - by their very nature - occur only
when enough people get hold of a new way of doing things and change their buying
at the SSD market - 2013 now clearly marks the 10th anniversary of a
distinct market period which I now think of as - the Modern Era of SSDs.
What do I mean by the Modern Era of SSDs?
It's when SSDs
changed from being a niche tactical technology which satisfied the needs of
some markets (ruggedized military / industrial storage and next generation
server acceleration at any cost) to a time when the market advance of SSDs as a
significant well known core market within the computer industry became a
historical inevitability - and when the only serious technology which could
displace an SSD from its market role was another SSD.
products which we would recognize as enterprise SSDs were shipping for several
years before 2003 - it was in that year, 2003 - when there was enough confidence
in the minds of enough people in the SSD market that the future of SSDs could be
much bigger (100x bigger) and different to what had happened before.

market had been influenced by those earlier articles on StorageSearch.com

to big upcoming changes in SSD market thinking?
Can I say anything
at all useful at this stage about what the 2nd decade of the modern era of SSDs
will be like?
I think it will be the time when a critical mass of SSD
users become more sophisticated in their understanding and use of different
types of SSDs - and when each part of the SSD market becomes less generalized
and more focused.
It's not just about the
SSD software, and
iit's not just about the
SSD chip technologies.
These simply outline possibilities. What's important - and what will become even
clearer - is the dividing lines and colors of application specific SSDs.
specific enterprise SSDs - is a technology trend which started
shipping more than 3 years ago. But - as I said above - markets happen when
enough people have decided to make them happen - and not simply because
pioneering products are available.
