There is a new storage vendor on the block – COHO DATA – who just exited stealth and launched their new product with the tag ‘Storage for the Cloud Generation’. I had the opportunity recently to catch up with Andy Warfield, co-founder and CTO of COHO DATA. Andy has a long history of involvement with storage and virtualization. A graduate of Cambridge University in the UK, he was involved in XenSource where he developed much of the low-level storage integration mechanisms for external storage arrays like NetApp and DELL EqualLogic. Andy gave me an in-depth interview related to their new product, and why certain development directions were taken by COHO DATA.
I just got a notification about this myself today. Apparently there is some interop issues with VAAI (vSphere APIs for Array Integration) & EMC RecoverPoint on EMC VNX arrays. It looks like the VNX Storage Processor (SP) may reboot with Operating Environment Release 32 P204 in a RecoverPoint environment.
EMC have just released today a technical advisory – ETA emc327099 – which describes the issue in more detail but is basically advising customers to disable VAAI on all ESXi hosts in the RecoverPoint environment while they figure this out. Hopefully it won’t take too long to come up with a solution to allow VAAI run in these environments once again.

Another storage vendor that I finally managed to catch up with at this year’s VMware Partner Exchange was Tegile. I was curious about the name, and I learnt that Tegile was a merging of the terms Technology and Agility. Tegile is another vendor that I have seen at various events, but have not had an opportunity to catch up with them in person and learn about their products. This time, I got an opportunity to catch up with Rob Commins (VP of Marketing) and Mike Recker of Tegile, and put a few questions to them.
Last week, I was at our VMware Partner Exchange event in Las Vegas. Apart from my own break-out session on vSphere 5.1 storage features, I wanted to catch up with a number of our partner vendors who are doing cool things in the storage space. One of these vendors is Dot Hill, a company from Longmont, Colorado, who have been making storage arrays for a considerable amount of time now, but one which does not seem to get a huge amount of exposure. I caught up with Matt Alsip, the Technical Marketing Manager at Dot Hill, to put my customary set of questions to him about their products and how their arrays integrate with vSphere.
Last year, NetApp announced a new host side cache accelerator feature to compliment their Virtual Storage Tiering (VST) technology. Rather than keeping all your data in flash, VST places hot data in flash while moving cold data to cheaper and slower media. NetApp are offering this as an end-to-end technology, from server to array controller (Flash Cache) to disk pools (Flash Pools). One of the major parts of this is Flash Accel, which was also announced in the latter part of last year, and is the server-side flash component of VST. On the back of their recently announced All Flash Array, NetApp are also making Flash Accel available to the general public.
