It’s been a while since my last post, but I couldn’t pass up this chance to talk about the latest news here at Coho. The announcements we made today have been in the works for a while, and I am proud to have been a small part of bringing the all-flash offering to market, having tested it extensively for the last several months. The series-C funding round is nice, too, of course!
Our all-flash offering enters a crowded market to be sure, but instead of becoming just another all-flash storage vendor, we’re approaching all-flash a bit differently here at Coho. We believe that whether to go “all-flash” or “hybrid” shouldn’t be a decision the customer has to make themselves, but rather, with intelligence about your workloads and how much flash they “really” need to function at peak performance, we can allow both all-flash and hybrid to co-exist within a single cluster and single namespace for a balance of unmatched performance and economics.
Our Cascade tiering technology allows each AFA chassis to balance two different types of flash, NVMe flash cards for the upper tier, and up to twenty-four 2.5” SSDs for the lower tier. All told, you can fit up to 50 TB of usable capacity in each 2U chassis (that’s before calculating space efficiency from compression, etc.)
Here’s a statement from our Technical Product Manager, Forbes Guthrie‘s own blog post about the release, and this is a key point I use when talking to others about some of Coho’s key value:
“Coho realized early on, that when you’re building a storage system with outrageously fast flash devices, and you have hungry servers waiting with insatiable appetites; don’t set out to funnel that I/O through an obvious choke point. Storage systems that come with pair of controllers, with no way to grow alongside your expanding storage needs, are a short-sighted design choice. With AFA storage, this is (obviously) way more critical.
All Coho DataStream systems are comprised of shared-nothing “MicroArrays”. Each 2U disk chassis contains 2 independent storage nodes; each have their own pair of 10 GbE NICs, their own CPUs and memory. As you add our disk chassis to a cluster, any type of Coho chassis, you’re adding controller power and I/O aperture.”
Well, I think that statement speaks for itself. I am really excited for what the future holds here at Coho. I feel that rounding out our catalog with this all-flash offering in the 2000f, entry-level hybrid offering in the 800h, to go along with our 1000h puts us in a very good place in the market right now. Add to that the fact that we use data intelligently to predict how much flash the customer needs for their workloads along with the ability to place it intelligently within a single namespace, across the different types of storage, provides us with the efficiency to compete very well against the competition, and I say: “Bring it on!”
