Clustering and NLB for exchange 2003?

[hannahsh]

What are the limitations of clustering Exchange 2003 We have 9 NT5.5 exchange boxs on remote sites which I want to replace with one central one (1500 users)

But if the demand on the exchange gets too great how can I add another node to share the balance Ms Cluster or Veritas etc

Take a look at "Considerations when deploying Exchange on an Active/Active cluster"

The quote that caught my eye "Microsoft does not recommend the deployment of Exchange 2000 servers or Exchange 2003 servers in an Active/Active clustered environment."

But with 1500 Users, you'll have no problems running the cluster in active / passive, on a beefed up server and a storage array. HP do the Proliant Packaged Cluster in serveral flavour, which would the job... subject to budget
