The Virtualization Practice

Tag Archive for vSphere 4.1

With the release of vSphere 4.1 there have been some great enhancements that have been added with this release. In one of my earlier post I took a look at the vSphere 4.1 release of ESXi. This post I am going to take a look at vSphere 4.1 availability options and enhancements. So what has changed with this release? A maximum of 320 virtual machines per cluster has been firmly set. In vSphere 4.0 there were different VM/Host limitations for DRS as well as different rules for VMware HA. VMware has also raised the number of virtual machines that can be run in a single cluster from 1280 in 4.0 to 3000 in the vSphere 4.1 release. How do these improvements affect your upgrade planning?

vSphere 4.1 Released – More Dynamic Resource Load Balancing

With the release of vSphere 4.1, VMware has added to their Dynamic Resource Load Balancing (DRLB) suite of tools that I hinted at in my post on Dynamic Resource Load Balancing that I wrote last week as well as providing new memory over commit and other functionality. In essence, vSphere 4.1 is more than a point release, this update includes many features that aid in security, reliability, and is a direct response to customer requests.
