Hi,

My SQl Server cluster has two nodes, both only have 2GB ram.

I want to upgrade the ram of each host, and keep the cluster on-line.

Is it safe to take one host offlince, uprgade it's ram, then bring it back up as part of the cluster, then repeat the process for the second host?

Does SQL Server need to be reconfigured to take advantage of this new ram?

Can anyone point me in the direction of documentation for this procedure?

Many thanks,

Kenny

Yes that is the procedure. We recently replaced a failed DIMM on our 4-node cluster. You just fail to another node, perform the maintenance, then fail back if you want.

SQL Server does not need to be reconfigured to take advantage of the memory.
