Folks, Dumb question but one that for some strange reason we can't get a definitive answer about. Xeon processors with hyperthreading seem to appear as two processors instead of one to both Windows 2000 Server and Server 2003. I thought that 2003 would be able to differentiate between the physical processors and the virtual processors. In addition, I've seen conflicting documentation on Microsoft's site stating that Standard Server 2003 supports up to two processors and supports up to four processors. That said, if we are building HP DL380G3's with hyperthreading would we need Enterprise Server 2003 or Standard? We're planning on using them for domain controllers and we're trying to remember why we ordered Enterprise Server 2003 when it appears that the much less expensive Standard Server 2003 would suffice. We're running DL380G3's and BL20pG2's with two processors and Standard Server 2003 seems to be running fine. But is it taking full advantage of the processors or running in some sort of crippled mode where it doesn't utilize the hyperthreading? Perfmon seems to show that it's using both of the physicals and both of the virtuals...but... Any info would be appreciated.
