Hi!
I have a design implementation question. We would like to upgrade from 2007(all roles installed on server) to 2013. We are a small firm with only 50 AD users and about 60-70 mailboxes all on Exchange 2007. Is it worth install the WNLB(don't want to spend money on a Hardware Load Balancer)... if we do so i have to split up the roles basically having 4 servers in total:
Server1-CAS Role
Server2-CAS Role
Server3-Mailbox Role
Server4-Mailbox Role
Or I can go with NO LB and having 2 servers in the Exchange 2013 environment :
Server1-CAS & Mailbox Role
Server2-CAS & Mailbox Role
And if I'm using the same urls for all services and your DAG failed over properly, the 2nd server would take over all connections.
Obviously I would setup the CAS Array/DAG/High Availability accordingly. What would you recommend? Our total Exchange 2007 store size is 120 GIG. What would you recommend?
Server specs:
HP DL380 Gen8
32 GIGS-Ram
500 GIGS-HD Raid 1 +0
Any advice or comments would be appreciated.
Thanks!
