Best way to setup 4 nodes in windows cluster

Postby guest » Wed Dec 10, 2008 11:21 am

2 Node Active/Passive Cluster:
- Simple, easy to setup (relatively)
- No need to worry about multi-failovers.

4 Nodes Multi-node, 2 Active Instances
- I think if you are going to have 2 active and 2 passive might as well
stick with option #1.

Multi-node, multi-instance configuration
- Complicated; now you have to take into account the affects of all nodes
failing over to one node and the performace issues that come with it.

Few notes:
- SQL Server Clustering, is Fail-Over clustering not Load Balancing; you can
achive Load Balancing by means of Replication.
- The Cluster nodes; share the disks that are configured for SQL Server and
the Quorum (SAN/NAS).
- In a multi-node configuraiton you might want to consider doing disk mounts
instead of dirve letters for all the hard-drives.

Thanks.
