I have been tasked with setting up a new exchange cluster on server 2003 and wonder if I should set them up as active/active? As I have only ever set up active/passive before I am after any advice I can get.
I will be running this on HP blade systems with the shared storage on EMC sym each server has 2 HBA's and 4 NIC's so I have teamed 3 and used the last as the heartbeat.
We are running two sym frames so the servers are powerpathed. The reason I am asking about active/active is that it seems a shame to have all the resourse on either one or other of the nodes rather shall sharing the load.

    Active/Active clusters have more restrictions on the load you can put on the server, because at any given time 1 node could be asked to support 2 exchange servers.  I think you're better off with Active/Passive personally.

    that said how would I do active/active if i wanted to?
    I have been tasked with at least building the monster on the existing blade servers but we are getting in some Unisys ES7000's with 16 processors each so they should be able to cope. I can't find anything on how to set this up.
    I already have an active/passive and fancy the challenge.

    Thats exactly what it is, just add a second EVS.   I'd start with .  This article is a good resource for A/A Exchange and contains links to docs that should explain how to set it up.
