I just started at a new company this week. They are using a clustered 64 bit Windows 2003 R2 installation with SQL 2005. The current setup is 2 node with quorum. One active one passive. I noticed that the active node is getting pretty heavy usage during the day and want to change over to active/active. The databases are all on the SAN with Fiber linking to the servers.

I can not seem to find any information on how to change the mode in Windows 2003. I seem to remember in Windows 2000 it was done from cluster admin, but nothing is there in 2003. I have been reading as much as I can, but at this point need some help on where to look so I can create the project plan and implementation steps etc.

I look forward to your input

There is nothing to change to make it active/active. You just need to have a SQL instance running on both nodes. That's what makes it active/active.

Make sure you've purchased licenses for an active/active setup though.
