Your boss wants you to install vSphere 4 server on two HP C-class Blades. Each blade
has two dual core CPU’s. How many vSphere processor licenses will be needed for this
setup?
A.
4
B.
12
C.
2
D.
8
Explanation:
ESX and vCenter Server Installation Guide, ESX 4.0, vCenter Server 4.0, page 108.
‘License keys have a certain amount of capacity. Capacity is based on the number of
processors in the host or the number of instances of the software asset. Dual-core and
quad-core processors, such as Intel processors that combine two or four independent
CPUs on a single chip, count as one processor.’
Therefore since there will be 4 CPUs in total, 4 licenses are required.
Really… the question says “Each blade has two..” there for the answer should be D. (8 Processors)
It’s per socket, not per core, so the correct answer is 4, i.e. 2 blades with 2 processors
