vSphere 4.1 Released


Vmware has announced the release of vSphere 4.1. This is not a major version release but there are some major features being released in this .1 version. The list of new updates and feature are long so I will go some of the most important or note worthy.

vCenter 4.1 is a 64bit application. This will allow vSphere to scale much higher than it previously could. vCenter 4.1 supports 3,000 VMs per cluster, 1,000 hosts per vCenter and 10,000 VMs per vCenter for an increase 2x or more.

Storage I/O Control which will now allow you to prioritize storage i/o, improve application performance, and set business priorities for storage resources.

Network I/O Control which will now allow you to prioritize network i/o by flow type like (iscsi, FT, and vMotion), improve application performance, and set business priorities for network  resources. This will only work with the Distributed Switch (vDS)  though so if your using vDS this is another reason why you should.

Memory Compression is to be used to optimize the use of memory freeing up space as needed. This feature is to help with memory over commit, reclaim performance, and safe guard against swapping.

Many other features are also included in this new update release around storage performance reporting and array integration api’s, DRS host affinity rules, HA has some more intelligence built into it, vMotion can migrate more vm guests at one time and the list goes on. To find more please take a look at the official release notes for vSphere 4.1. The download is available here.

I am very impressed with what is in this new release and can’t wait to get my lab upgraded so that I can start testing all this goodness. Vmware is definitely showing why they are the leader in virtualization and is raising the bar even higher. The proof or course will be when companies start to deploy 4.1 in private and cloud environments.
