We are planning to have two clustering environment, both will be Active/Passive which would require 4 servers. Someone in our group suggested to use the same passive node to handle both cluster environment to save money. Is this possible? We plan to use sql 2008 R2 enterprise edition.

Yes it is possible with Active/Active/Passive configuration . but you have to consider lot of factors like the Hardware configuration,Memory,disk space ,Network bandwidth so that performnace should not be impacted incase when both nodes will run on passive node .

HTH...

As Nary said this is possible, remember to ensure that the drive letters of your cluster do not clash. This may be a problem if you have different teams setting up each cluster.

Hope this helps,
Rich

Basically use 3 nodes instead of 4, this will save on hardware and yes it is perfectly viable!

also there is no such term as active\active\passive. A cluster is either active\passive or active\active whether you have 2 or 8 or (in the case of Windows 2008) 16 nodes!

Thank you all for your response. In a few weeks, I will start building the two sql cluster environment with 3 nodes. Thank you again.

Regarding the cost issue, you will save money on hardware, but be sure you realize that SQL licenses for passive nodes in clusters are no cost.

A node can be part of two clusters? Anyone have info on how to set this up?

No. What is being mentioned is a 3 NODE CLUSTER, with ONE instance running on NODE ONE, another sql instance running on NODE TWO and the THIRD NODE being the passive node for failover of either, or both of the ACTIVE nodes.
