VMware PEX 2010: a short comment on DRS IO February 14, 2010

Posted by vneil in Virtualisation, VMware.

There has been a good amount of coverage from the VMware Partner Exchange in Las Vegas last week but one bit of news that caught my attention was the mention of DRS for IO. The only blog post I saw it mentioned was in this post by Duncan Epping. After a quick google I found this great post by Ian Koenig over on his blog from last September.

It looks like if it was mentioned at PEX it might be coming soon, I had kind of hoped it might have been in vSphere as the next logical extension of DRS after CPU and Memory resource scheduling.

The way we run our current cluster  is one big cluster with test and production VMs spread across all the host servers with their VMDKs also mixed on datastores. They are distributed into appropriate  resource groups and all this helps to even the workload and make full use of all resources.

The cluster is not heavily burdened at the moment and we are continuing to P2V Windows servers and deploy new Linux servers onto it. I see IO DRS as an extremely helpful tool with the growth of the number of VMs in the cluster to keep the necessary prioritising of production over testing.

In the meantime I’ll keep an eye out for any more news on IO DRS.
