Looking at a Netapp 2040 with an extra part-populated SAS disc shelf running iSCSI. There will be 28 x 450GB 15k SAS discs in total. I want to make sure we get better performance than we have without a SAN and with future capacity.
How many users do you think this could service assuming every user is a heavy exchange user, heavy sql server user and we have 20 servers in total (mixed SQL, Exchange, file and application servers).
The servers are all running on top of ESX vSphere for which the vmdk files will hopefully live on the SAN.
thanks in advance.
