Xeon E5-2600 OS CPU To Core / SMT Thread Mapping On Linux. It Matters.

Ages ago I blogged about the Intel topology tool and mapping Xeon 5500 (Nehalem EP) processor threads to OS CPUs on Linux. I don’t recall if I ever blogged the same about Xeon 5600 (Westmere EP) but I’ll cover that processor and Xeon E5-2600 in this short post.  Fist, Xeon 5600.

The following two screen shots are socket 0 and socket 1 from a Xeon 5600 server. Socket 0 first:

The Exadata Storage Server is the same whether the database grid is X2-2 or X2-8. The X2-2 database hosts are also based on Intel Xeon 5600. On the other hand, the X2-8 database hosts are based on Intel Xeon 7500 (Nehalem EX). This is a relevant distinction when thinking about database encryption.

Will Oracle Ever Release Sun Servers Based On Westmere EP and Nehalem EX Processors? Yes.
