Hyper Threaded Processor Support

Hi,
I know that this must have been answered many times before but looking at
the supported processors for SQL 2000 or 2005 when it mentions maximum
number of processors is this the maximum physical processors? If Standard
edition supports 4 processors, is this 2 hyper threaded or 4 hyper threaded
processors?
Thanks
Chris Wood
Hi
Standard supports 4 processor sockets, so on a HT or dual core, it looks
like 8 processors to the OS and SQL Server. That is supported andworks. SQL
Server 2000 SP3 added support for HT processors.

SQL2005 Standard supports 4 processors which could be 4 hyper-threaded
processors or 4 dual core processors or 4 single core processors without HT?

|||This issue confuses everyone so don't feel dumb. SQL was released before
Hyperthreadong or dual-core processors. When Hyperthreading was released,
MS eventually came to the decision to license processor sockets, not cores
or virtual processors. So, you count actual, physical processors for
licensing. SQL Service Pack 2 has the correct code to count processor
sockets, not processors. SP3a and SP4 have some code tweaks to better deal
with some synchronization issues from HT and Multi-core processors.
Again, do not worry about the logical processor count shown in Windows.
Count the actual physical processors for correct licensing and limitations.
