Having DAG and CAS Array on 2 Exchange 2010 servers with all roles 2 NICs or 1?
Posted on 2014-01-01
I'm in the process of migrating 1000 users from Exch 2003 to 2010. I will have 2 servers and on each will install all the roles.
I would like just to know if my configuration is proper or not!
didn't decide yet if it's going to be virtualized or physical servers. but here's the Hardware Specs I am having on mind in both cases!
1- 16 GB ram each server
2- 2 NICS (1GB) on each server for CAS Array. (I'm not sure if it will be ok to have CAS Array with mailbox roles with one DAG) ?
3- 4 Terabyte HDD split on the two servers as following
Server 1 -
Server 2 (Same configuration as Server1)
Is there anything I'm missing?
Second thing I would like to know, In case of installing all the roles on 1 server and adding a second server with all roles as well for redundancy! Does it need to have a second NIC?
and in case of second NIC would for the CAS array, would that affect the mailbox roles since the CAS Array should handle all the client requests including access to mailboxes which will be installed on the same servers where the CAS roles are!
I would appreciate any hints
