According to Everymac: "As originally shipped on April 7, 2009, Apple reported that the Eight Core custom configurations hold 24 GB of memory. On December 4, 2009, Apple formally added support for 4 GB modules and increased the maximum memory to 48 GB. However, third-parties have confirmed that the Eight Core configurations actually support 96 GB of RAM using 8 GB modules. Apple additionally reports that the operating "system supports up to 32 GB in Mac OS X Server v10.5" and "up to 96 GB in Mac OS X Server v10.6"."
Can't suggest more than that, as ours only has 24GB.
Also can't see a Quad 2.93 listed...

the specs listed by you are 2 x 2.93Qcore which is an 8core Xserve 3,1. The max ram is 96gb 12 x 8GB 1066 DDR3 ECC.
As Stephen's said 10.6 will allow you access to the full 96gb of ram, the single QCore CPU 2009 (3,1) Xserve only shipped as 2.26ghz
