For a customer who is looking at keeping costs down, they are wondering whether setting up a virtualized Exchange 2010 server with all the core roles installed would be possible. So the mailbox, CAS and hub all on one virtual slice. The customer has around 200-300 mailboxes.
I know that its hard to give a guess for sizing, but I was wondering if a 4 core, 16 GB RAM build on Server 2012 would be sufficient, with the storage obvioulsy being SAN. I know this is dependant upon mailbox size and usage, but I don't have those numbers unfortunately. Would the 4/16 build be sufficient? Too much?
Any further information around this would be great. Thanks.
