Understanding CPU Licences in vSphere Server Standard

Hi,

I am just after a little info about understanding the physical CPU licenses included in vSphere Server Standard and how many CPU cores are allowed.

A long story short I want to set up a FT environment consisting of two ESXi hosts with two physical CPU's in each host connected to a central SAN for a total of 48 Cores (24 Pr a host).

Would the vSphere Server Standard License suit this need?

Thanks,

Marcus
