Q

Clustering products for Windows

We're running a W2K and SQL2K server farm with around 40 database servers under management -- Intel based and working to evaluate high availability software to address single points of failure for our databases.

Can you help me identify vendor choices for helping manage high availability with a failover flavor -- not replication or log shipping?

The vendors/products that we have on our list are PolyServe, Veritas -- don't know much about them yet -- and MSCS. We have reservations about MSCS based on previous bad experiences with a SCSI implementation. We will be going with Fiber/SAN implementation for our next generation of HA servers.

Thanks for any help!

I am happy to provide you with a partial list of vendors who have clustering products on Windows.

As you said,

  • Microsoft MSCS
  • Veritas Cluster Server -- Full disclosure: I work for Veritas.
  • Polyserve Matrix
  • Others that I know of include:

  • Legato Co-StandbyServer(tm) AAdvanced
  • Open Source Cluster 3.0
  • NSI Double-Take
  • These are the ones I am aware of. Hope this helps.
