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 Sakac’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
