Simple answer. No it does not need to be clustered. Complicated answer... maybe. I mean the real trick is how many (and what type) of changes will you need to make if it is unavailable. In most cases your answer will be none. We can operate without making changes to the DS for a couple of days. If that is true then you don't need the cluster. Replication or shipping of the DB/Logs is needed though for any type of DR. Of course there are drawbacks to this too. I mean If you use transactional replication then when the primary is gone you cant make changes anyway (until you turn the subscriber into the publisher). So it all depends. Hey, I can come out and work on this with ya. It sounds fun and right up my alley.

Does the primary IMA Data Store really need to be clustered, or is this more complication than it is worth. KISS principle, etc.? I appreciate that high availability is important, but isn't the integrity of the database even more important. Without a Data Store, what's the worse that could happen during the 96 hours, you can't make changes?? If something was seriously wrong the master IMA Data Store cluster node A, would we want the second cluster to take over? Is there not a further chance of corrupting data by having this nice-ity?? If the Data Store becomes unavailable, presumably an app server can still boot from the contents of the LHC? thanks, Brian ============================================================================ == This message is for the sole use of the intended recipient.
