We are in the process of getting a new servers for our company since we ar moving to a higher ERP system.
this is the layout I am looking at.
1 server AD
1 Server SQL Server
1 Server Exchange
10 PC desktops
30 Thin Clients
I have 2 points I would like you pros to help me with.
1-How do I do a failOver system ?
I have searched and it seems that I could go 2 directions.
a-Windows Failover... But can It be done on the whole 3 servers ? what about licensing ? Ive read that for passive mode
(meaning my backup server would be sitting just waiting for the main to die to take over) I have no licensing fees ?
Can I cluster my AD server ? My Exchange ? Can they be cluster to a virtual appliance (so I can replicate all 3 in 1 physical server ?)
b-Symantec replication ... In that case there would be another server into play that would replicate all the data.
but in that case can I replicate to a virtual servers all my initial 3 servers ? again what about licensing ?
c-What version of Windows Server does failOver ? standard can do ? 64bit can do ?
2-Does Exchange Server do replication ? how ?
