VMFS recommended Datastore size in ESX 3.5 U2 and ESX 4.0 U1

Hello All,

I am running 10 ESX Servers (4 CPU socket each) on a HP EVA 4400 SAN with about 50 VMs

These Vms range from DB servers to Web Server etc

What is the recommended size to create a VMFS datastore? Some people tell me, 500GB, other sources tell me 2Gb is fine.

Does creating a 1-2GB VMFS datastore impact performance as oppose to a 300Gb to 500GB?

Let me know what you think.
