SQL Server Forum / Other Technologies / Clustering / August 2008License question
In setting up a 2-node cluster (active/active) do I need to have an additional SQL 2005 Enterprise license for the second node? Also, I'm new to clustering and I just want to verify that I can do an active/active 2-node clustering with SQL 2005? I see alot of talk about active/passive but I'd rather have active/active and was wondering if there's a limitation or particular reason for active/passive You will need to license any nodes that have an active SQL instance hosted on them. If you have a single-instance cluster with two nodes, then one is always a failover node and does not require a license. If you have 4 nodes and three instances, you still have a failover node and only have to license three instances. Two nodes with two or more instances require full licensing of both nodes.

But thing you have to consider about active-active is if either partner fails; the remaining partner will take the full load. So when configuring hardware for the server make sure it is configured to handle 2x its normal load. Thanks. SignatureMohit K. Gupta B.Sc.
