Did some pNFS proponent slip a love potion into the coffee at EMC? Suddenly it’s pNFS time at the company known for its reluctance to embrace file sharing and filesystems in general. The purple prose is flying, with Chad Sakac declaring himself “a big fan of the application of NFS” and Chuck Hollis extolling the “inherent simplicity and ease-of-management of NFS.” The NetApp guys must be amused by the bear hug from Hopkinton, but many are seeing deja-vu all over again.
One of the most interesting areas covered at VMworld 2010 was the new storage features in vSphere 4.1. There are two main features I want to cover in depth as I feel they are important indicators of the direction that storage for VMware is heading: Storage I/O Control (SIOC) and vStorage API for Array Integration (VAAI).
One of the major new components in Virtual Machine Hardware 7 is the new Para Virtualised SCSI (PVSCSI) adapter. When it first came out there were a number of posts regarding the much improved I/O Performance and latency reduction this new adapter delivered, such as Chad Sakacâ€™s I/O vSphere performance test post.
vSphere Land just announced the results for their Top 25 Virtualization Bloggers vote. We’re impressed by the voting turnout, and can’t argue with the results: Every one is a great VMware resource! We’re especially pleased that Gestalt IT is so well-represented, with three of our authors making the list!
Chad Sakac recently tweeted about some issues EMC were having with VMware and there was a predictable and rather pathetic dig from NetApp about perhaps this being a result of EMC having too many product lines and having too much to QC.
This weekend I finally had the chance to catchup on some of the new storage features released as part of vSphere 4.0, there are quite a few changes to cover, some of them quite exciting.
Hiding in the shadow of the huge VMware vSphere 4 announcement was a very interesting introduction by EMC: PowerPath/VE. As I mentioned in my post on storage changes in vSphere 4, PowerPath/VE plugs into the new pluggable storage architecture (PSA) found in vSphere 4 versions of ESX and takes over the decision-making and heavy-lifting tasks related to communicating with storage systems.D
