August 29, 2017 - Western
today that it has agreed to acquire Tegile. The price was
Editor's comments:- Tegile was already using a
customer of WDC drives (SSDs, HDDs and the InfiniFlash white box SSD array from
SanDisk). So Tegile's flexible pricing models for buying storage were already a
good showcase for how to integrate these technologies in a user friendly way.
of the business risks of Tegile's business model was that its ideal customers
were buying usable storage based on
model pricing and cost expectations which seemed predictable and scalable
upto about the tail end of 2016. Unfortunately those cost predictions have
been shattered and ruined by the rising prices of
and associated shortages in 2017.
A few years ago I discussed the
risks of the utility model with Tegile - which at that time seemed to be
containable technically (because they were obviously related to expectations of
reliability, learning from similar customers doing similar things and
efficiencies). Tegile's business model meant that external finance could depend
on a predictable curve of customer value and cost.
When memory prices
rise by 50% or more (instead of going down) those curves mean that repeat
customer sales can't follow smoothly from what happened before.

benefit. So that's why I think Tegile couldn't sustain itself as an independent

Expands its Graveyard with Tegile Acquisition - a blog written by AFA
competitor Nimbus - says
"It's widely known that Tegile was running out of cash. No
acquirers showed up as the product is ill-suited for the cloud. Existing VC's
saw Tintri's horrific IPO and concluded that unprofitable storage companies are
DOA in the public markets. The Tegile deal was a loss for the VC's that pumped
$175 million into it (WD being among them). Rather than take the full loss, WD
paid well under $100 million to acquire it."

WekaIO compares cloud storage pools to IBM FlashSystem
July 12, 2017 -WekaIO - a
today emerged from stealth and
details of its cloud-native scalable file system which the company says can
deliver performance comparable to

Editor's comments:- The notable thing for me in this announcement
was that WekaIO uses a performance benchmark compared against an
IBM FlashSystem 900 (the
decendant of the RamSan

says "Utilizing only 120 cloud compute instances with locally attached
storage, WekaIO completed 1,000 simultaneous software builds compared to 240 on
IBM's high-end FlashSystem 900. The WekaIO software utilized only 5% of the AWS
compute instance resources, leaving 95% available to run customer applications."
an ambitious positioning statement and offers users a glimpse into the kind of
performance they can get by using flash assisted cloud services. Like other
modern SSD fabric software software - "WekaIO eliminates bottlenecks and
storage silos by aggregating local SSDs inside the servers into one logical
pool, which is then presented as a single namespace to the host applications."

why you need better storage analytics - says Enmotus
15, 2017 - Using SSDs as its prime example - but with a warning shot towards
the future adoption of NVDIMMs - a new blog -
analytics impact performance and scaling - by Jim O'Reilly - on
the Enmotus blog site -
describes how soft errors can contribute to application failure due to
unexpected sluggish response times even when the data is automatically repaired
by SSD controllers and
when the self-aware status of the SSDs is that they are all working exactly as
That's the needs analysis argument for storage analytics
such as the software from Enmotus
which supports the company's FuzeDrive
Jim says - "Storage analytics gather data on the
fly from a wide list of "virtual sensors" and is able to not only
build a picture of physical storage devices and connections, but also of the
compute instance performances and VLANs in the cluster. This data is
continually crunched looking for aberrant behavior."
Editor's comments:- in my 2012 article -
will SSDs end
bottlenecks? - I said "Bottlenecks in the pure SSD datacenter will be
much more serious than in the HDD world - because responding slowly will be
equivalent to transaction failure."
And in a 2011 article -
the new SSD uncertainty
principle - I shared the (new to me) wisdom collected by long term
reliability studies of enterprise flash done by
STEC - that many
flavors of flash controller management contained within them the seeds of
performance crashes which would only become apparent after years of use as the
data integrity algorithms escalated to progressively more retries and stronger
ECC to deliver reliable data from wearing out (but still usable) flash.
I agree with Jim O'Reilly. You do need more sophisticated datasystems
analytics then whether or not an SSD has failed.
The variable quality
of latency can be a source of
long delays in server DRAM too.

How do banks use big memory systems to detect fraud?
January 9, 2017 - In the early 2000s I started hearing stories from vendors
about how their fast memory systems were helping banks to not only ease the
choke points in their transactions but also provide insights into fraud
A new white paper GridGain Systems
provides a good introduction and synthesis of
various roles of in-memory computing in accelerating financial fraud detection
and prevention (pdf) which includes many named bank examples.
paper describes how in memory computing provides the low latency data sharing
backbone which is needed to enable pattern detection for fradulent activity to
be assessed in real-time while at the same time enabling genuine transactions
to proceed quicky.
Among other things, the paper says...
move from disk to memory is a key factor in improving performance. However,
simply moving to memory is not sufficient to guarantee the extremely high memory
processing speeds needed at the enterprise level... Clients who have implemented
the GridGain In-Memory Data Fabric to detect and prevent fraud in their
transactions have found that they can process those transactions about 1,000
times faster." ...read

real-world applications its customer base averaged 5.4x more effective

Kaminario offers free iPads to boost K2 tryouts
Editor:- October 4, 2016 - I saw a promotional email offer from Kaminario today which
I think may backfire as it seems to be in direct conflict with the ethical
principles of buyers in many large organizations.
email says "Test and evaluate a Kaminario K2 all flash array with up to
50TB capacity for as little as $1.25 per GB and iPAD management console for 45
days. Try it today and the iPad is yours to keep."
comments:- I think the offer will turn off buyers in big companies - because
the inducement of a free iPad to take part in the evaluation sounds like a
personal gift rather than having any benefit for the evaluating organization.

Nimbus re-emerges from stealth with 1PB / U raw HA SSD
August 9, 2016 - Nimbus
Data Systems has emerged from its self imposed exit into

of a new range of Ethernet/FC/Infiniband attached rackmount SSDs based
on its new
OS with GA in Q4 2016.
Entry level products start in a 2U box with
50TB raw capacity for under $50K and for larger configurations Nimbus says its
ExaFlash offers an effective price point as low as
effective gigabyte (including all software and hardware).
density boxes in this product line - D-series models - will have 4.5 PB raw
capacity in 4U (12 PB effective).
- I haven't seen details - Nimbus says there is no data network between the
storage arrays themselves, guaranteeing that performance truly scales in
lock-step with capacity and with consistent latency.
video above shows the 4PB raw ExaFlash
Editor's comments:- if there are to be sustainable
roles in the future
enterprise SSD systems market for AFA vendors which previously sold arrays
of SAS/SATA SSDs - and who don't own their own semiconductor fabs - the only
viable ways to establish such platform brand identities are with SSD
software and architecture.
There's a huge gap between the technological
aspiration which Nimbus talks about and the weakness of its past marketing and
the kind of
funding which we've
seen competitors in this market burn through in the past with mixed results.
In the next few quarters I hope we'll hear more from Nimbus about its
business development plans and customer adoption.
roadmap to the
positioning of many flash array "startups"
Pure Storage says its AFA revenue in Q1 2016 was more than the
leading HDD array brand
Editor:- June 21, 2016 - Scott Dietzen, CEO -
says in his recent blog -
a generational shift in data center storage - "...not only were we the
fastest-growing storage vendor named in IDC's report, but we cracked of the
top 10 storage vendors (for revenue) globally not just for all-flash storage,
but for ALL external enterprise storage."
this result in the real world of market revenue tracking is broadly in line
with a long range
prediction I made in 2009 - in which I said "50% of the (enterprise)
hard disk market will no longer exist in 5 years, and none of it will exist in
10 years (except in museums)."

memory intensive data architecture emerges in a new family of
latency roled boxes - unstealthed by Symbolic IO
Editor:- May 25,
2016 - 1 petabyte usable storage in 2U along with a
flash backed RAM
rich server family which uses patented CPU level aware cache-centric data
reduction to deliver high compute performance are among the new offerings
today by Symbolic IO which has
emerged from stealth mode.
Founder & CEO, Symbolic IO - Brian Ignomirello, said - "This
industry hasn't really innovated in more than 20 years, even the latest
offerings based on flash have limitations that cannot be overcome. Our goal at
Symbolic IO was to completely redefine and rethink the way computing
architectures work. We've completely changed how binary is handled and
reinvented the way it's processed, which goes way beyond the industry's current
excitement for hyper-conversion."
Giving a clue to
performance Ignomirello said - "One of our early tests, allows us to
run a full cable class content delivery network over 80+ nodes, while streaming
80+ full-featured movies simultaneously on one channel and requires less than 8%
of the CPU capacity and we had plenty of headroom to run more. IRIS
(Intensified RAM Intelligent Server) is 10,000 times faster than today's flash."
comments:- I hadn't spoken with Symbolic IO (when I wrote this) but my
first impression was that the company is in line with at least 3 strategic
trends that you've been reading about on StorageSearch.com in recent years:-
company profile summarizes their capability like this...
IO is the first computational defined storage solution solely focused on
advanced computational algorithmic compute engine, which materializes and
dematerializes data effectively becoming the fastest, most dense, portable and
secure, media and hardware agnostic storage solution."
about the company's background see this article -
IO Rewrites Rules For Storage on Information
From the marketing point of view it's interesting to see that
in its launch press release Symbolic IO positions itself in the
context in this way "IRIS... is 10 times faster than 3D XPoint."

Pivot3 acquires NexGen
Editor:- January 27, 2016 -
today it has agreed to be acquired by Pivot3.
comments:- The last time I wrote about Pivot3 was 7 years ago. I had a
good feeling about their
architecture thinking which was being applied to hard drive arrays but
I viewed it more as a valuable
efficiency boost to
buy breathing space for the
last gasp years of
enterprise HDD rather than the new direction I was focused on - which was
heading towards the solid state storage datacenter. And so - from my point of
view - I had nothing more to say.
On the other hand we're heard
times in recent years.
Combining the software and architecture from
these 2 companies could produce a platform with characteristics comparable to
the best upwardly stretched efforts of much better known competitors if
Pivot3 and NexGen can draw the integration boundaries in the right places (and
get it done quickly enough).
7 out of top 10 SSD companies are systems companies
January 7, 2016 - Rackmount SSD companies dominated the top 10 zone of the
34th quarterly edition
of the Top SSD
Companies published today by StorageSearch.com

back at the dominance of rackmount systems makers in past editions in this

Q2 2013 when it
was 8 of the top 10 companies.
The compelling technology
necessities driving this trend were noted in my
SSD year transitions article. The top level idea is the same today as it
"The rack has become the most important form factor at
which level enterprise SSD vendors must focus their strategic product ideas.
What we're seeing in the market today at the rack level - are efficiencies and
competitive advantages which accrue from combining and integrating design
factors at many levels within large SSD arrays (at the memory utilization level,
the SSD controller level, the drive interface level, the flash array
organization level and multiple levels up and down the system software and apps
software stacks). Mastering the design possibilities of SSD at the rack level
enables new levels of competitive advantages for vendors."
the precise details which have changed since 2013. Hence all those recent AFA
and big data SSD acquisitions.
And the market
has changed too (90% of enterprise vendors will disappear) which means it's
less safe for SSD outsiders to sit back and wait to see what happens.

Dell buys EMC - the SSD view
good for Dell-EMC - long
good for AFA and hybrid competitors - short term
and changes for SSD suppliers - short term
Editor:- October 13, 2015 - Dell yesterday
it has agreed to acquire EMC
for approximately $67 billion. The acquisition also included EMC's stake in
the storage software
company VMware - which
will remain in public ownership.
Editor's comments:- In the
short term this fixes a problem for Dell (its weakness in enterprise storage)
and offers a credible way for EMC to adapt to a long term future in which its
storage products become
commoditized and accessible to smaller businesses (something which Dell has
historically been good at with its server business.)

but a long term SSD centric summary goes something like this.
have become a commodity. And there is little or no scope for genuine
differentation options to be offered within the server market. (Being able
to offer the same memories or SSDs in servers as everyone else - does not
decommodify server product lines BTW.)
In contrast - enterprise storage
- which in the HDD and post tape library and post optical storage era (2001 to
2008) had been coasting towards oblivious commoditization - has been
temporarily reprieved from that fate (2009 to 2018) by the disruptive
impact of SSD memory technologies which enabled the construction of
5 to 6 role
differentiated types of new storage boxes which could deliver value to
users in ways which were technically unimaginable and unfeasible with
classically tiered memory and storage.
Having misfired its original
entry into the enterprise flash market in
2008 - EMC has
in recent years managed to accumulate credible industry leading proprietary IP
and product lines in 2 of the 5 above storage box segments (which will satisfy
projected enterprise storage needs in the post HDD era) meanwhile treading
water in the other 3 main box segments (indicating its aspiration to occupy
part of those other crowded beachheads if possible).
Assuming all goes
well with the acquisition process - the Dell-EMC product line will enable EMC
storage to be more competitive in the short term with existing products and to
maybe credibly add another notch to the list of product types for which it has
aspirations for clear leadership.
on the server and storage markets which are emerging from
SSD centric software
and data architectures will mean that traditional product lines from both
vendors will shrink away.
And those lost revenues will stay gone
forever. The old ways and the
orders won't be coming back. That's why it's important for both companies
to draw in new smaller customers and to nurture them (if possible) into the
new sustainable sold state storage and server product lines.
about impacts for the SSD market?
Anyone who competes with Dell or EMC
will - for the next year - have an easier ride - due to the inward focus
which sucks away the attention of the talent following such acquisitions.
SSD market as a whole will continue to supply memory and SSDs to the new company
- and probably can look forward to getting more business in 18 months time.
it won't simply be more of the same. Some SSD vendors may see big changes
when Dell EOLs systems and modules which are cannibalistic and compete within
the combined product lines.

fast rackmount SSDs from EMC, IBM, Pure... which is cheapest?
Editor:- July 9, 2015 - In a recent blog about the
competitiveness of fast rackmount SSDs -
I Hate Cost/GB Discussions - Michael Martin,
FlashSystems Specialist - IBM
- leads you through a series of arguments to convince you that - when
measured on a 5 year ownership basis (against a very specific set of parameters)
his company's fast
rackmount SSDs are cheaper to own than competitive models from EMC and Pure.
other things Michael says - "Why is everyone so focused on the initial cost
when it comprises such a small percentage of the "real" or total cost
of the storage array?"
condition question which Michael Martin looks at is - what is if EMC gave
you a FREE VMAX? How would that compare to the IBM V9000 FlashSystem's TCO?
I like that style of analysis - because it's one I've used a lot
myself in the past 12 years or so - in various market forecasts where I
looked at the cost of one type of product being zero but another type of
product (SSD) still being cheaper or better.
comments:- recently we've seen survey data from
Tegile suggesting that
for a significant proportion of enterprise users the ROI on their enterprise
flash investment can be as little as 1 or 2 years - which suggests that looking
at the 5 year cost, or the initial purchase cost are equally unreliable
For most users - the uncertainty of capturing reliable
predictive cost benefit data to justify the acquisition of enterprise flash
arrays was discussed in my article -
the Astrological Age of Enterprise SSD Pricing.
The reasons for
choosing one system over another include so
preferences and associated customer service values that the 5 year
predicted cost from a particular web site are not likely to be the decisive
factor for most users - who will prefer to trust their own analysis.
long as you don't take the rankings in Michael Martin's blog too seriously - as
gospel - and don't come away with the idea that IBM's FlashSystem is always the
best and cheapest fast rackmount SSD - it's a fun read. ...read
Conspicuously absent however in this discussion -
given the 5 year cost justification timeframe - is a new class of fast
rackmount SSDs which will be emerging in the next year - based on arrays of
2.5" NVMe SSDs
- which will have the same impact on this segment of the market (IBM, EMC,
Violin etc) as did
flash on RAM SSDs.
