Windows 2003 Enterprise - 16 Way

[gtlscot]

Hi

Scenario we have recently upgraded a older server from 4 way to 8 way CPU.
When 4 way the CPUs were configured to run with hyperthreading. When we
added more processors we switched this off as Enterprise is not meant to run
with greater than 8 CPUs. Even though the server now has 8 physical CPUs
utlisation is still vey high. The server is not scheduled to be replaced for
another 12 months and we would wish to implement a cost effective increase in
server resources.

We were interested to know as HT is not physical cores will the OS manage to
run if HT is turned on again without an upgrade to Datacentre

Thanks

Graeme

AFAIK, only 'real' cpu's count, ie 'cpu sockets'. HT is not even 'complete'
core, but only partial execution unit, while the rest of the logic shared.
What does it cost you to try?
