A couple questions here. 1. Thoughts for mission critical SQL hosted on VMware? 2. Is SQL 2008, 2012 supported on VMware? We have an SLA of 99.5 which does not include maintenance windows. We use iSCSI storage. We also have vSphere 4.1 We currently run a 3 Node Windows 2003/SQL 2005 Active/Active/Active Cluster for HA. Wanting to move to Windows2008/SQL2008 or SQL2012. I am considering vSphere5 HA/DRS. I am not concerned about performance in Vmware more concerned about meeting and exceeding my SLA. I am interested in your thoughts, since I am running iSCSI I cannot do Windows Cluster to protect the operating system. I am thinking of DB Mirroring.. ??? thank in advance.

You should be concerned about performance. Because you'll need to spec your VMs with that in mind. We're over two years with 100% uptime with all production SQL Servers on VM.

I indicated I was concerned about performance as I would defiantly build/size properly.

Anyone else have some feedback?

Thanks for your reply.
