I am looking to upgrade an HP VSA virtual storage solution to either IBM v3700 or HP MSA 2040.
In both configurations, the machine comes with 24 * 900 GB 10K SAS drives.
I have 3 hosts that will need to connect ( vMWare essential ) , and was thinking to connect with 2 SAS each host.
Some people say it is better to connect with Fiber Channel for higher IOPS, is that true?
The system will run +-10 virtual machines, from wich 2 SQL , one Exchange 2010 and then file servers, DC etc...
Pros/cons for each one please
