IF i have 12,000 mailboxes which is spread on 5 exchange 2003 mailbox servers, and i want to put them in a cluster how will the cluster be like? because exchange 2003 cannot take 12,000 mailboxes on a single machine ( i meant in a two node active passive cluster)
Do i need to create 2 or 3 pairs of 2 node cluster ( like the 1st 2 node cluster carry about 5000 mailboxes and the 2nd cluster carry 5000 mailboxes and the 3rd 2000)
can it be done on a 4 node A/P cluster.
PS: I think i am not clear on more than 2 node cluster
