delivering storage for the cloud generation. Led by a team of XenSource/Citrix
virtualization and storage industry veterans, Coho Data is enabling businesses
of all sizes to build their own high performance Amazon-style storage for their
data. Inspired by the highly scalable, commodity-hardware based approaches of
public clouds, the company is developing the first flash-tuned scale-out storage
architecture designed for the private cloud that delivers unparalleled
performance at public cloud capacity pricing.

Who's who in SSD? - Coho Data
by
Zsolt Kerekes,
editor - StorageSearch.com
Coho is active in the
rackmount
SSD server market.
The company's product line began with
SSD ASAPs (auto
tiering / caching appliances) and has recently been augmented with compatible
all flash arrays.
Coho's products are application servers (in our
enterprise SSD latency
differentiated silos model).
In common parlance they are one of
the many subset architecture types in the SDS market.
The company is a
relative newcomer to the enterprise SSD market having first entered the pages
of
StorageSearch.com in
November 2013.

| Coho Data now shipping 2U
MicroArray hybrids |
Editor:- March 6, 2014 - Coho Data today
announced
general availability of its first product - a 2U
SSD ASAP called the
DataStream
(an SSDserver 4/E) - which
integrates PCIe SSDs,
hard drives and a
server into a web scale expandable unit (using an internal 52 port 10GbE fabric
switch) to implement what the company refers to as a "MicroArray"
designed with the philosophy of
"Turning
Tiering Upside Down (pdf)" to deliver a base building block unit of
180K IOPS
performance (4KB).
Editor's comments:- you may judge for
yourself the lofty scale of Coho's
ambitions by this market
soothsayer quote which they integrated in the launch press release - "By
2017, Web-scale IT will be an architectural approach found operating in 50%
of Global 2,000 enterprises." | | |

| Coho Data gets $25 million
for 2U SSD ASAPs |
Editor:- November 5, 2013 - Coho Data (which recently
emerged from stealth mode and operates within the
hybrid systems - SSD
ASAPs market with a cloud
market focus) - today
announced it has
got $25 million in Series B funding - led by new investor, Ignition Partners,
and also including existing investor, Andreessen Horowitz.
The funds
will accelerate Coho Datas R&D and go-to-market efforts as the company
prepares for general availability of its
Coho DataStream system later
this year.
Editor's comments:- What I like about Coho Data is the clarity
about what it offers:- "Build your own high-performance Amazon-style
storage for all your data."
What I'm less gung ho about, however,
is the apparent efficiency.
For example - one of the "difference"
features which Coho talks about on its website is the easy way that users can
scale to multi-petabyte installations - using its 2U building blocks which have
Intel
PCIe SSDs inside and
some hard drives.
The
example shown on this
Coho page says you can build a 190TB hybrid apps server which does
900K IOPS in 11U of rackspace for $530k list. That may sound good compared to
museum grade alternatives - but Coho's solution takes 2x to 3x
the rackspace of leading pure SSD HA based systems to do the same thing.
Now
- size isn't everything. And neither is scalability. And for many users the
ease of managing incremental growth might be compelling reasons to look at this
type of product. But most of you pay more per square foot for your floor space
than Amazon - so an "Amazon style" product proposition may not be the
best for you. | | |

| Coho adds
all flash nodes to its hybrid product mix |
Editor:-
May 20, 2015 - Coho Data
today
announced
it has closed $30 million in Series C funding, bringing its total funding to
nearly $67 million.
The round was led by March Capital Partners, with
additional participation from HP Ventures and Intel Capital as well as existing
investors Andreessen Horowitz and Ignition Partners.
Coho Data also
announced the general availability of its first all-flash storage node, the
DataStream
2000f a 2U server based system which uses
Intel's
P3600
2.5" NVMe SSDs
and conventional SATA
SSDs.
Coho says that using a judicious mix of its variously
populated SSDservers
(which includes micro-tiered
hybrid systems as
well as the new pure SSD nodes) "empowers customers to efficiently support
any application at any scale, all from a "single pane of glass"
management interface, and all at less than $0.10/GB usable per month." | | |

| Efficiency is important for
web scale users - says Coho |
Editor:- October 9, 2014 -
Facebook
as a file system - a web scale case study - a new blog by Andy Warfield , cofounder
and CTO - Coho Data
- made very interesting reading for me - as much for revealing the
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
story.
When you
read
it you may get different things out of it - because it's rich in raw
enterprise ideas related to
architecture,
software, and
dark matter users.
All of which makes it hard to pick out any single quote. But here are 2.
- re -
the miss
match between enterprise products and user needs
Andy Warfield
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."
- re efficiency
and utilization
Andy
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." There are many more I
could have chosen. ...

| Decloaking hidden segments
in the enterprise |
Editor:- May 28, 2014 - StorageSearch.com today published
a new article -
Decloaking
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.
Hey - that means SSD-world is like a map of the
US before Lewis and Clark.
If you're a
VC should this make
you anxious or happy?
If you're a user - maybe that's why no one is
delighting you in the way you think you deserve.
That's what led me to
write my new article.
