I am just after a few expert comments about how best to carve up a new SAN to work with ESX 4.1
This is hyperthetical at the moment, but currently our existing HP EVA San has 4 disk groups, each with a bunch of disks from various trays based on type of disk etc. The disk groups are then split up in to VDisks and presented to servers. Most of the VDisks we created were around the 500GB, some smaller, some larger
The Vdisks were then presented to the ESX Cluster and formated for use on ESX.
My question is, is it better to create slightly larger LUNS, of around 2TB each, or smaller ones of about 500GB each and then spread guests around between them?
I just have the opportunity to start again and wanting to know some thoughts.
Please don't just send me links to white papers I am after personal experience examples if possible.
