What’s New in vSphere 4.1 – Performance Improvements

MikeLaverick MikeLaverick Profile: MikeLaverick

So here’s the back story. A couple of weeks before yesterday’s GA of vSphere4.1 myself and the rest of the bloggers who make up the vCommunity – were privileged to be given 3 closed sessions all about what is new in vSphere4.1. The first rule was the fight club rule, in that we couldn’t blog about vSphere4.1 until yesterday when the embargo was lifted… That seems fair to me. It meant we could all spend time writing articles up front, ready to publish over the week. My articles more or less map to those three sessions. Although because of the volume of the content, I ended up splitting up mine into four parts. The first part is all about performance, Part 2 is about ESXi, Part3 is about VMware Clustering and Part4 is about VAAI.

I’ve been on the beta programme for vSphere4.1 for sometime, but in all honesty didn’t get round to installing the beta until VMware reached out to the bloggers in this way – and that spurred me to get the new version set-up in my labs (yes, I have more than one!) so I could take the necessary scene grabs.  Anyway, for the detail – which is where the devil lives

So part one is all about performance. In it chat about how there is a very small change to the set-up routing to vCenter – and then move on to cover the new SIOC and NIOC options – the former which introduces a new version of Distributed vSwitches (4.0 and 4.1 DvSwitches). I also discuss the new “memory compression” and VMotion enhancements.
