We have windows server 2008 two node cluster active/passive. We have few named instances of sql server 2008 and r2. Our management is planning to virtualize almost everything to save money. Their plan is to virtualize cluser. So our plan is: 1. Create two virtual nodes on existing cluster. 2. Failover one physical node to virtual and then remove physical node. 3. Failover second physical node to second virtual node and remove second physical node. 4. This is production server and applications are connected to different instances.
My question is based on your experience whether it is possible. If possible any impact on application.
Not yet know. But I think vm nodes will share the same storage. Idea is that once failover, virtual nodes will take control of disk resources. Sachin if you did this practice can you share whether it is possible? if possible what we need on storage side?
We are planning to virtualize our cluster. Right now we have 2 nodes active/passive cluster, physical nodes. This is data centre. Our plan is to consolidate everything through virtualization and move into UCS. In UCS we will use virutal cluster nodes instead of physical. So our plan is to add 2 virutal nodes to existing cluster and then remove physical. If picture is still not clear, let me get some more info from vm, server team.
Ok if I understand it correctly what you mean is that you will be adding virtual nodes to the existing physical windows cluster and then install sql server cluster across the 2 virtual nodes which will be part of the virtual sql cluster.
After Monday and Tuesday even the calendar says W T F ....
I think you need to talk to your server admins. Hardware and config is supposed to be the same on all nodes of a cluster. I doubt doing this will even pass the cluster checks.
