what does Tegile's customer survey tell us?
June 25, 2015 - A
published survey conducted among customers of Tegile reveals some
interesting insights into the demographics of Tegile's business but also - just
as interesting - provides a spectrum of weighted answers about why people bought
enterprise flash arrays and the perceived benefits.
Among the many
results - the most interesting for me were:-
- "36% plan to use their Tegile storage to accelerate the
development of new products and services. Customers can create read/write clones
of production databases. This enables them to get new applications into
production faster without consuming a lot of storage space."
comments:- that's a classic enterprise SSD advantage related to a pain point
which I was discussing with users over 10 years ago.
don't have the performance freedom which SSDs deliver - but who struggle even
to keep their legacy platforms running sluggishly - know there must be better
things they can do with their raw business intelligence - but are too scared to
interact with the production data. And designing new systems based on sampling -
doesn't give the full picture.
survey findings which I've commented on above - probably apply to any
leading AFA vendor and not just Tegile.
- Tegile says "51% of customers expect to see an ROI in 12
months or less."
Editor's comments:- that's confirmation of
something I said in my article -
year of the enterprise
"what's driving this confidence is that their
customers have done the pilots- they've done the product tweaks - the biggest
customers have finished their cautious rollouts - and they're coming back asking
for more than more. The user mood is changing from - can I afford to use SSDs?
- to a realization that - I can't afford not to use SSDs." (October 2011)
Tegile's survey confirms is that the same advantages which were first
experienced by early adopters do indeed trickle down and deliver similar
impacts to mainstream users (if the products are
a way which is attractive enough to tempt new customers to experiment.
Here are some interesting
results which are specific to Tegile's business.
- Re the importance of offering "unified" connectivity (FC+IP) - "over
half (53%) were using more than one storage protocol with their Tegile
Editor's comments:- that's a higher proportion than I had
assumed. Which also is consistent with the broad spectrum of traditional storage
suppliers that Tegile has been displacing (another aspect shown in the survey).
the article - Why do people use Tegile Flash Storage?
- Re customer satisfaction? - 92% of responders said that they'd
Editor's comments:- that's a good story for a company
whose business model has been so reliant on
external funding to
sustain its growth.
But how sticky is brand loyalty in the enterprise
flash market? Especially when we're entering a period where I predict that over
of enterprise SSD brands will disappear?
Let's just say that high
customer satisfaction is an excellent achievement but that a customer who has
switched once because they saw a good reason to do so - is a customer who could
easily switch again. While Tegile has some sticky service and software
solutions in its product delivery - don't be beguiled by statements like the
above - if and when you consider the IPO.
And - on the
of extrapolating inferences from surveys - 96 users - the customers who
took part in the survey - aren't the whole market.

SolidFire gets another $82 million funding
October 7, 2014 - SolidFire
it has closed an $82 million Series D round of funding, bringing its total
funding to $150 million.
New investor Greenspring Associates led the
round along with a major sovereign wealth fund, with participation from current
investors NEA, Novak Biddle, Samsung Ventures and Valhalla Partners. SolidFire
will use the additional funds to extend its global reach.
building blocks of SolidFire's SSD systems are 1U
iSCSI rackmount SSDs
which include 10x 2.5"
SSDs. At that level it's the same as 100 or so other competing systems.
If you want fibre
channel access - you add a special 1U adapter rack to the native IP array.
So it's expensive - but keeps the unit costs of the most common building blocks
down - compared to including native unified storage in each rack. So in the case
of a big installation - it's a reasonable cost optimization tradeoff.
key difference is
software architecture and the fact they use a
architecture type of RAID
- which they call "no-RAID".
In SolidFire's no-RAID (which
is really big RAID) - the data is more widely dispersed across the drive
population than in classical (small architecture) RAID.
is much less disruption to data access and
performance when a drive
because SolidFire's software can manage upto about 100 racks as a raw storage
resource (1,000 SSD drives) - so the impact of a single drive down is small.
Users also have a high degree of flexibility as to how they micro manage
different virtualized segments of storage to meet their different QoS goals.

CacheIO decouples iSCSI storage capacity from performance

PS - I asked Bang Chang,
CEO of CacheIO if he had a white paper which talked more about the company's
cache architecture and philosophy. He sent me this -
Availability Deployment (pdf) - from which I've extracted these quotes...
- re network cache appliances - "At CacheIO we believe that network
cache appliance is the best storage architecture to decouple performance from
capacity and achieve the best of both worlds.
Once deployed as a "bump
in the wire" performance accelerator, our network cache appliance can also
deliver additional value added services... Compared to server-side Flash cache,
our network cache appliance is a shared resource that is more scalable, more
reliable, supports clustered applications, and most importantly allows
customers, especially cloud service providers, to monetize performance by
dynamically allocating resources based on changing SLAs."
I found it
interesting to see that in addition to conventional connections (SAN and
InfiniBand) their HA
paper also mentions emerging PCIe fabric.
- re operational transparency - "Implementing CacheIO network appliance
requires no change to existing applications, servers, or storage. CacheIO can be
slotted in, turned on to accelerate applications, and turned off if necessary,
often without needing to stop the applications."

FIO had already indicated that its revenue
from its known biggest customers would decline for a few quarters - so the
financial results are not a great surprise. But the NexGen announcement has

end of the SSD adoption scale - compared to the well known big customers which
have until now dominated FIO's business.
Will it work?

PCIe SSD market which
it largely helped to create as a significant new part of the server ecosystem.
But it will require a different type of marketing and business development
approach to convert the potential of NexGen's technology into an equivalent

the other hand if you add NexGen's hybrid iSCSI IP to the marketing magic of
Fusion-io - it's safe to predict that the iSCSI market will soon be getting a
wake up call the likes of which it has never seen before.
...Next on the SSD world domination agenda - create better value
in the cost sensitive iSCSI market
Editor:- April 23, 2013 - The iSCSI market hasn't been a
fertile business development ground for SSD sales - a factor which I ascribe
to the mood prevailing at its birth.
At the start of 2001 - when
the idea of iSCSI first attracted interest on the web - the
storage market was still in
a recession which would continue for another 2 years. Users could buy new
or little used servers and storage recycled from the spending spree of failed
dotcom companies for next to nothing. There was already a proven fast way of
doing fast network storage - fibre-channel
which had been around since
1994 (but it was complex to set up). Those various factors meant that iSCSI
evolved - by necessity - into a cheap, simple to set up and maintain storage
ecosystem for frugal applications which needed data.
was nothing hard wired into the technology which prevented it from being scaled
up - most of the early attempts by vendors to nudge iSCSI into the fast lane
with dedicated hardware accelerators failed. There was no real customer
appetite in the iSCSI base to encourage vendors to push for fast random IOPS
or low latency. iSCSI was the frugal way of doing complicated network
That's another reason why - prior to 2013 - none of the top
10 enterprise pure SSD array companies started in iSCSI. There wasn't enough
market demand for the kind of low latency and fast IOPS which could open enough
doors for SSDs in storage cabinets to make it worthwhile. Instead, most of the
iSCSI arrays which have been in the market until recently were originally
developed around technology optimized for FC SAN or were simply iSCSI HDD
arrays with some SSDs thrown into some of the bays. When you saw "iSCSI"
on the datasheet of a fast SSD you knew it had most likely been added
to a model which had already been optimized for another market.
could say that iSCSI has been a safe haven for enterprise
hard drives - because
whenever there has been a tension in the feature set between the cost of
incremental capacity versus the value of incremental performance - it was cost
- and getting the cost down as low as possible - which usually won.
explained in my Petabyte
SSD roadmap article a few years ago why one day - even the mantle of low
cost per raw terabyte wouldn't be enough to protect delinquently slow and
ineffcient hard drives from being evicted from enterprise network storage
racks. And this culture shock will be knocking at the door of the iSCSI market
from various different vendor directions in the coming year - with increasing
I was pondering these factors last week when I was waiting to
Rosenthal, Senior VP Marketing Astute Networks who
wanted to talk about the
of new models in their ViSX family of fast-enough iSCSI rackmount SSDs -
which have upto 45TB of raw SSD storage in a 2U rack which with
can deliver $2,000 / TB and even with dedupe switched off - comes in at about
$5,000 / TB while being able to offer more than double the IOPS of much higher
priced competing SSD systems.
The first thing I asked about was the
company's iSCSI accelerator chip - which is one of the two technology factors
which give them an edge in iSCSI. I had heard about it many years ago - but the
company doesn't say much about it now. Len told me they were now on the 3rd
generation of their iSCSI accelerator chip. The 1st generation had been
designed for a US Navy project to enable fast access to embedded storage
located around a ship while using COTS (Commercial Off The Shelf) servers and
In Astute's current ViSX systems I think you can view the
iSCSI accelerator as being the technology which buys the time (in latency cost)
which can then be spent on dependable real-time dedupe.
me that although Astute have always known this gives them a theoretical
performance advantage compared to competitors who use similar types of flash -
it's only when he engaged Demartek
to do some comparative testing recently and gave them a free hand to explore
the differences - that they realized just how good their systems were. (I've
seen summaries of these benchmarks - and they do confirm the advantages of the
Astute's new systems do now seem to offer a hard to
beat SSD package for users in the mainstream iSCSI market. Len described
this as "making flash affordable for the mid market."
earlier generations of iSCSI flash were too expensive for most users. But the
current generation - not only offers attractive pricing - but comes with proven
technologies - and cost effective replication - by what the company calls
availability groups" (pdf)- which enables users to choose which
systems provide failover clustering - and whether that's local or remote. In
addition to providing data continuity when things fail - this scheme can also
provide load balancing and imporved performance in the normal (unfailed)
One of the things which came across clearly from talking to Len
is that Astute Networks is totally focused on the iSCSI SSD market. They
know the market, they know the apps - and they aim to be one of the leading
suppliers in this niche. For them iSCSI isn't something on the tick list - it's
the whole list.
