The juxtaposition of these concepts in colocated
cloud servers presents
risks which were reported
recently by researchers at Worcester
The research team used a combination of
techniques to first create a virtual machine on the same Amazon cloud server as
a target machine (a technique known as co-location). They then used the
co-located machine to spy on the target. By observing how it accessed
information in memory, they could determine when it was retrieving its RSA key.
Then by charting the timing of the memory access they were able to deduce the
key's actual numeric sequence. ...read the summary
OCZ does that 3rd generation SSD firmware cloud thing (but
gives it a better name)
Editor:- October 16, 2015 - It's no longer
just the newcomers to the enterprise SSD market who are doing that 3rd
generation / co-operative (whatever you want to call it) SSD controller
firmware and host stack collaboration thing.
OCZ this week
announced they're doing it too.
It's available in the
Saber 1000 (2.5"
cloud oriented, read mostly SSDs). And they've got a better name for it too - "Host
Managed SSD Technology".
"Our new Saber HMS SSD, together
with a software library and API, enable for the first time (in OCZ's product
line) software orchestration of internal housekeeping tasks across large pools
of SSDs, thus overcoming performance barriers that were simply not possible to
address without this technology" said Oded Ilan, GM of OCZ's R&D
Team in Israel.

that run on them."

Warfield says - "Efficiency is important. As a rough approximation, a

can out of it while it is in production."

Micron turns up the heat for adoption of 2.5" PCIe SSDs

endurance as "50PB of drive life".
Micron is also offering half height, half length PCIe SSDs in the new range -
but to my mind it's the 2.5" drives which are the significant part of this
I wrote about the impact these new drives could have
on traditional PCIe SSDs and
SAS SSDs in an
article 12 months ago.
summarize the main points in that... the new form factor for PCIe will displace
high end SAS SSDs and likely make the 12Gbps SAS drives the last generation of
SAS as "performance drives".
SAS SSDs will in turn replace
SATA SSDs as the
removable drive of choice in traditional legacy fast-enough enterprise
The new 2.5" PCIe SSDs will open up new markets in cost
sensitive incrementally upgradeable fast SSD racks.
At the high end of
the server side accelerated market, however, and particularly in
dark matter data
centers where the rack is seen the replacement unit - I'm sure that good old
PCIe SSD cards and modules will continue to hold their ground - because they
have lower packaging costs and can be designed to be more efficient than smaller
earlier this week - traditional PCIe SSDs will also facing pressure from
storage SSDs. But MCS won't impact 2.5" PCIe SSDs.
you start selling shares in any particular company - I'm talking here about
market juggling and realignments which will take 2-3 years to have a material
affect on existing market sizes and revenue. These changes won't happen
overnight. And these game changers in the
enterprise SSDs market
aren't taking part in the context of a zero sum game. The enterprise SSD
universe is expanding.
And here's another thing.
Last year I
told Micron's top SSD marketers that they weren't in tune with the needs of
enterprise SSD specifiers - because they had hopelessly slow and antiquated
processes for extracting technical information of the type that serious buyers
They seem to have taken those criticisms on board - because
now you can swim around in the info they've got about their new enterprise SSDs
on their web site - without having to sign NDAs and without waiting weeks to
talk to the person who knows what's missing on the datasheet. Still some details
missing - but it's a vast improvement on what they were doing before.
of you may think it's ironic that it's not Micron who's doing the flash thing
for memory channel SSDs. But bear in mind that semiconductor companies have to
feed the fab. And their priorities are to engage in established markets where
there is already known demand for millions of chips. Big memory companies don't
usually get involved in blue sky system innovation - except in
ORG type wolf packs.
Micron's got its own thing going with hypercube memory. And - as I've
said before - if that flies - it's another gating point for flash (if flash is
still around when that happens).
Fusion-io positions ioScale for huge SSD installations
January 16, 2013 - Fusion-io
has released a new PCIe
SSD called the ioScale
(3.2TB on a single half length PCIe slot) which is aimed at technically savvy
customers who have the potential to use thousands of cards in their
installations in new
dynasty enterprise SSD apps.
Pricing is under
$3,900 / TB and the minimum order quantity is 100 units.
comments:- When you first look at this product - you might be tempted to
think - So what? - isn't it very similar in capability to other products which
FIO (and others) have shipped already?
In one way you'd be right. The
ioScale's hardware design is based on FIO's experience in making low cost PCIe
SSDs for the workstation market - which is as close to
price pressure as FIO gets at the present time.
But the ioScale is
aimed at a special class of enterprise super users - whose apps and companies I
call:- new dynasty
and dark matter
Fusion-io told me
that when they did market research into the kinds of customers who were already
using their SSDs they discovered the big enterprise SSD customers could be
segmented into 2 groups which superficially had similar performance needs - but
were very different in the ways in which they valued issues such as:-
- compatibility with traditional software apps,
- how they handle reliability,
- how often they refresh and replace their infrastructure.
traditional enterprise customers have the profiles which everyone in the
industry knows about and aims their products at - but the new type of enterprise
customers have needs which are only starting to clarify - and for this latter
type of customer - SSDs are a strategic business enabler - because they can
convert efficiencies in raw computing technology into real competitive
- how they assess the cost / benefit of features within SSDs
Fusion-io is one of the few companies in the world which
already has a set of these latter cloud / data factory economy customers
who each have already got thousands of high performance PCIe SSDs - and who
have the ability to scale up substantially if their requirements are met and the
SSD enabled economy grows in the directions expected.
Rick told me that
these customers do want
performance, and low cost - but they don't need many of the bundled frills
which are deemed to be necessary for traditional enterprise SSD customers
legacy apps report faulty drives they change the drive or the rack. When
uber new dynasty SSD
users report faults - they route around them. Then when the time comes to
upgrade the CPU and storage capacity per square foot of that region in the
datacenter - the whole lot is forklifted out and replaced - faulty and unfaulty
racks - makes no difference.
Also - in these apps - hot pluggable
drives are a frill which is simply not worth paying for.
matter SSD customers - at which the ioScale is aimed - also know much more about
the technical limitations of their infrastructure - and have the technical
expertise to change things to suit them better - if they think it's worthwhile.
So - for example - the ability to dive into SSD APIs and change their apps
code to get speedups or other new functionality - is something they will do -
whereas traditional enterprise customers prefer all new hardware to work with
pre-existing software in a tweak-free environmoent.
conversation with Rick White - I referred back to the
software (which FIO launched in
August 2012 -
and which enables users to convert a standard server and a bunch of
PCIe SSDs into a
traditional SAN compatible
My assessment of that product shared with readers at the time -
was that if it satisfied the needs of a small number of super users - who could
each buy maybe hundreds or thousands of such systems - that made it worthwhile
for FIO to bundle the concept and launch it. I thought the analysis I had seen
in other places - which compared it to traditional rack SSDs was completely
missing the point.
Rick confirned my analysis was closer to the mark -
and many times in our discussion we returned to the problems in the SSD market
caused by faulty and incomplete
market research and
mistaken understandings of what the real issues in the market were.
way of summarizing this is - that if you ask a bunch of people who go to a
trade show - what do you think about SSDs? - you're going to get a different
result to when you talk to people who are already deeply engaged in the SSD
market, have already done a lot of SSD projects and who spend nearly all their
waking hours thinking about what more can they do if they had even better SSDs?
not that the traditional market research gives you the wrong answers - it's more
that - if you're not in the right place in the SSD market then you don't
understand enough to pose the right questions - and you probably don't have
access to the people who will ultimately decide the answers.
isn't the only SSD company who is getting value business insights by
researching its strategic customers.
I reported last year that
SanDisk had adapted its
approach to enterprise customers by deciding to support competing hardware

SolidFire launches SSD cloud appliances
June 21, 2011 - SolidFire
has announced details of its first product - an
iSCSI SSD appliance
designed for cloud storage
applications which the company says can scale to 1 petabyte capacity (which
takes 100 nodes with current models).
Performance within a SolidFire
system is virtualized separately from capacity, allowing cloud service providers
to prescribe and guarantee performance to every volume within the system.
comments:- the company's
elements include features such as:- self healing data protection, always on
reservation-less thin provisioning , inline real time compression,
cloning and snapshots,
and dedupe, as
well as adjustable managed
throughput performance windows.
These are the essential
characteristics of what I called "bulk storage SSDs" in my article
roadmap to the
Petabyte SSD - although in that article what I had in mind is that by 2016
that a PB archive SSD library should fit into a single 2U rackmount.
that seems far fetched - remember that a lot of things can change in the SSD
market in 5 years.
5 years ago -
in 2006 - the enterprise server flash SSD market didn't exist. 2006 was
the 1st year of the
market and there were only 36 makers of SSDs - compared to 300 today.

All storage fails - design is choosing management preferences

CEO of CloudSigma (based in
In it he discusses what he calls the "Myth

Patrick Baillie says "When building out our cloud we
made the decision early that we preferred more frequent low impact problems than
infrequent high impact problems. Essentially we'd rather solve a simple small
problem which occurs more frequently (but still rarely) than a complicated large
problem that occurs less frequently. For this reason we chose not to use
SANs for our storage but
local RAID6 arrays on each
computing node." ...read
Overland says cloud tech can scale NAS VTLs
October 14, 2010 - Overland
that it has acquired MaxiScale
- a cloud storage
Dr. Geoff Barrall, CTO and VP of engineering at Overland
Storage said "The logical next step for us is to create a clustered
scalable NAS forming a
local cloud of storage. When the opportunity arose to acquire MaxiScale's
well-regarded technology, we took notice. MaxiScale's architecture will provide
our customers with the ability to scale hundreds of (our)

StorSimple fills "missing link" in cloud storage DNA
Editor:- May 4, 2010 - StorSimple has
exited stealth mode - announcing a bunch of collaborative customer supply
agreements - and disclosing info about its Armada storage appliance - which is
designed to reduce the cost and simplify the integration of
cloud storage within
datacenter applications and infrastructure.
Just as application specific SSDs
are the future for the SSD
market - StorSimple's Armada system can be regarded as an application
specific SSD ASAP
which includes features such as real-time
dedupe and cloud
The simplest way to think about it is as "the
missing link" between the promise of cloud storage and its practicality.
The companies which have agreed to be named in StorSimple's company launch press
release (Amazon, AT&T, EMC, Iron Mountain, and Microsoft) seem to think it's
a noteworthy part of cloud storage DNA too.
New Image for Cloud Storage
Editor:- January 13, 2010
- a new article on
discusses on-low cost and no-cost cloud storage offerings from Google.
author David Coursey (and his commenting readers) make some interesting
comparisons with Microsoft 's SkyDrive.
I loathe the term "Cloud Storage". But I have to admit we're stuck
with it. So today I changed the graphic on the
online backup and storage
The old one - with the tag about "Spellerbyte was
cooking up a new business plan which involved online web backup" - was
appropriate when it was first published 10 years ago - but no longer fits this
market's image today. I resisted the temptation to use an image compatible with
the business metaphor of "sad losers" or "big black hole for

|"What scares me is
when companies fall into the trap of trying to architect a single application to
work across multiple different cloud providers. I understand why engineers are
attracted to this.... Unfortunately, this effort eats into the productivity
gains that compelled the organization to the cloud in the first place."|

back at the online storage and cloud market|
by Zsolt Kerekes,
|This market has seen
many ups and downs in the past 15 years. |
The online backup market
flared most brightly at the height of the dotcom boom crazy days in the late
1990s. That convinced me to create a dedicated page for this subject. You can
see an archived copy of the online backup page circa 2000 -
Back then - I called it "Edrives & web based storage" - because "online
backup" hadn't yet become a standard term back then.
unconvinced about the business models for many of these companies - which mostly
relied on unsustainable web advertising. I'd been making my living from the
sustainable kind (of advertising) - and knew the difference.
enough - this segment of the storage market got itself a bad reputation for
vendor churn and undependability in the long term.
You can get a
flavor of how the online backup industry changed (and our web site too) in the
years which followed, by clicking these archived links:-
we're recently experienced another recession (caused by the credit crunch of
2008) and you've got to ask yourself this question...
If banks can
fail - then why should you trust ANY online backup provider with your data?
answer is - you shouldn't. Because
shown these services can disappear overnight.
But on the other hand -
there are many examples of where online backup has helped their customers
survive in the event of floods, fire etc.
A pragmatic approach - would
be to use 2 different types of offsite backup - which do not have common modes
of failure due to sharing software or geography. That's the way ahead for this
