Will a single Dell R710 /w dual Intel 6 core CPU and 64 GB RAM with boot to SAN (Compellent) run the 3 following virtual servers? Exchange 2010 (120 mailboxes with 400GB total database size) and 2 servers running SQL 2008 R2? Each SQL server has a single database of less than 12 GB. I have 2 of the Dell R 710 servers and would like either load balancing and/or failover but can't find any definite planning information as to what I consider a small implementation. Both of the R710 servers will have Windows 2008 R2 SP1 Enterprise as the host.
