Hello all.

I've been asked to upgrade our virtual server hosts to get max performance.  The servers in question are:

HP ProLiant DL365 G1

I have found HP's recommended CPU's to upgrade.

My question is about the CPU themselves.  To upgrade the servers, I would need to purchase is:

Dual Core AMD Opteron 2222 (90nm)

Frequency: 3000
Socket Type: F
Power Wattage: 95
Bus Speed: 1000
Stepping: Not Specified

AMD offers quite a variety of F socket type processors.  Is it possible for me to get a higher core processor of the same socket type?

I was taught that as long as the socket type is the same, you are pretty much free to pick what ever CPU you can afford (PC's).  Is there a different rule of thumb with servers?

On paper, will this work?  I'm considering the following:

Six Core AMD Opteron 2427 (45nm)
Frequency: 2200
Socket Type: F
Power Wattage: 75
Bus Speed:  4800
Stepping:  D0

Since this is our production VM hosts, the last thing I would want is to crash all of the VM's contained within, so I would be more than happy sticking with HP's recommended CPU's.
