How many vSphere processor licenses will be needed

[SATHISHVIJAY]

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?  PLEASE EXPLAIN

A.4

B.12

C.2

D.8

The answer is 4. This is because each Blade has 2 Dual Core CPU. Upto 6 Cores you don't need to worry, in this case only dual core. If it goes beyond 6 cores, then licensing will change.

2 x 2 = 4

Thanks,

hello Sir

i am bit confuse i red somewhere that vmware provide licenses on per physical core basis.And in above scenario, i would say 2  because server has dual core and it might has one physical cpu.

Please clear my doubt...

It depends on the processors, the blades can have 1 or 2 processors. Assume there is only one processor on a blade then YES you will need 2 licenses. If the cores were to increase more than 6 then you will need the Advanced and Ent Plus license. The Gen8 with latest Xeon processor can have upto 12 cores per processor.

you need only 4 licenses as you have 4 HP C- Class Blade server with Dual Core processor.

if each Blade is with two processor and six core then only a single license will be required to each server.

if the processor count and Cores count will increase then you need more licenses.
