sql server clustering : 2 running sql to join in a cluster
I currently have 2 separate SQL Servers under the same domain, running different databases each and having different hardware. We are getting an SAN to centralize the data. If i move the data of both SQL Servers to the SAN then can i configure both sql's to be as one cluster? Are there any articles or so on this procedure please?
You would have to create a cluster and then either detach the DB's and
reattach them, or take backups of the DB's and restore them onto the new cluster. -- Tom ---------------------------------------------------- Thomas A.

Thanks Tom for your quick reply.
Therefore a cluster (if i am not mistaken) can be of different hardware right? i.e. there is no need that physically they are identical hardware right?

Actually, dissimilar nodes are not supported. Indeed, you can't cluster
just anything - even if they are identical. They must be in the Windows Catalog *for clustering*. http://www.microsoft.com/windows/catalog/server/default.aspx?subID=22&xslt=globalsearch&qu=cluster&scope=1 -- Tom ---------------------------------------------------- Thomas A.

Hi

And they must be purchased as a certified cluster solution. Hardware
sometimes requires different configuration settings when used in a cluster vs. when used in a stand-alone configuration. -- Geoff N.

You can cluster hardware that is not listed in the Windows Catalog. However, there are support issues and already expressed by Michael. I strongly recommend that you purchase clustering solutions only from the Windows Catalog. The question really is one of whether you should do something, and if you think about the entire purpose of high availability, it should be apparent that you want to do it the right way and the right way only. -- Russ Kaufmann MVP - Windows Server - Clustering ClusterHelp.com, a Microsoft Certified Gold Partner Web http://www.clusterhelp.com Blog http://msmvps.com/clusterhelp
That's what I meant. A client forced me to put together a cluster with
unsupported hardware. Then we went into production. Then, it went BOOM. That's probably the biggest "I told you so" in my career. -- Tom ---------------------------------------------------- Thomas A.
