"perception" of 4 cpus in ML530G2 2 way server !?

Noted something interesting while looking over our 2 new ML530G2 servers .. "Physically" both servers have (2) 2.8ghz cpus..But from both the Insight Manager 7 performance of cpu view and the Windows 2000 server os, shows 4 engines ? Perhaps this is the Intel Hyperthread resource ? is there some White Paper or document that discusses this in the new Proliant ML G2 type servers?

I have 4 DL360 G3 servers. All 4 servers are configured the same yet 2 of the 4 think they have 4 CPUs rather than 2. I changed the NUMBER_OF_PROCESSORS parameter to 2 and then rebooted but it still goes back to 4. These are 1U servers that have a max of 2 CPUs. The OS is Windows 2000 Advanced Server.

Anyone?

I must say that these forums suck. Painfully slow to load each page and it can't even get the submit correctly. I hit submit on the post and then nothing happens. No redirect back to the forum or anything. It just sits there.

Is there a problem? This is hyperthreading and is enabled by default in the Rom Based Setup.

More info can be had from:

The truth is out there, but I forgot the URL..
