Exadata Database Machine X2-8 HP Full Rack

In my recent post entitled Exadata Database Machine X2-2 or X2-8? Sure! Why Not? Part I, I started to address the many questions folks are sending my way about what factors to consider when choosing between Exadata Database Machine X2-8 versus Exadata Database Machine X2-2. This post continues that thread.

As my friend Greg Rahn points out in his recent post about Exadata, the latest Exadata Storage Server is based on Intel Xeon 5600 (Westmere EP) processors. 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.
