the original plan presented to my bosses, was a single standalone server with local storage only. (1.5TB SAS). HP DL 360G5 Quad Core, Dual Processors, 32GB RAM. To consolidate 7 physical servers, DCs, SQL, ISA, Print Servers, 3 already VMs, All these servers at present do multiple roles, e.g. DC/ISA/File/Print/SQL. They appreciated this was all eggs in one basket, and didn't have alot of money to do this, but then decided lets to Two servers and shared storage, so vMotion, DRS, HA could be done.
But after you add-on the VMware licenses, and support costs, for vCenter and Enterprise at x4 licenses for processors, not alot left for storage!
I think it's the toss up between two standalones or two with shared storage (enterprise), but if the storage doesn't work or is slow, Enterprise is a waste of money!
It's try-ing to avoid downtime if one ESX unit should have a system board fault.
any thoughts, each server is about £4k, 4TB Storage £1k, VMware Licenses+Support, £6k
so if the iOmega cannot hack it, it's a waste of £7k! (and local storage would have to be purchased!)
