Coho is active in the
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

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

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
PCIe SSDs inside and
some hard drives.
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.
- 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.

it has closed $30 million in Series C funding, bringing its total funding to
nearly $67 million. |

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

2.5" NVMe SSDs
and conventional SATA
Coho says that using a judicious mix of its variously
(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."

as a file system - a web scale case study - a new blog by Andy Warfield , cofounder

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
it you may get different things out of it - because it's rich in raw
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."

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.
