Also, Apple has upped the build to order option to 8TB of Hard drive space (4x2TB) from 4TB.  3.33GHz Xeons processors and 2TB hard drives have been out for quite awhile, so this isn’t a big surprise.  In fact, 2TB hard drives have reached commodity status (two generations of iMacs) with prices falling below $200 for consumer level versions.   Apple’s Xserves also get the 2TB hard drive (x3 slots=6TB).  Apple has thrown in a build-to-order RAM update as well.  Apple now stocks 4 GB RAM modules, doubling the build to order capacity of the quad-core Xserve to 24 GB and the 8-core Xserve to 48 GB. Interestingly, Apple states that the total capacity of the Dual Processor Xserves is 96GB, but only with with Snow Leopard.  That means that 8GB modules will work in this machine. The 3.33GHz Processor will add $1200 to the base configuration.

Each additional  2TB hard drive is $550.
