In addition to this morning's Mac Pro updates, no pre-Macworld pro announcement would be complete without new Xserves. Apple also introduced its new dual Quad-Core (up to) 3.0 GHz Intel Xeon 5400 Xserves today, which is, of course, 1U rack-optimized and "the most powerful Apple server ever." It, too, has two PCI Express 2.0 slots along with up to 3TB of internal storage with a plethora of other bumped options. 

Your standard Xserve configuration runs for $2,999 and looks like this:

• a single 64-bit 2.8 GHz Quad-Core Xeon processor with 12MB of L2 cache and a 1600 Mhz front side bus;
• 2GB of 800 MHz DDR2 ECC FB-DIMM RAM, expandable up to 32GB;
• a single 80GB SATA Apple Drive Module;
• dual Gigabit Ethernet on-board;
• internal graphics;
• two FireWire® 800 and three USB 2.0 ports; and
• an unlimited client license for Mac OS X Server version 10.5 Leopard.

You can also get it built-to-order with dual 2.8GHz or 3.0GHz Quad-Core Xeons, internal RAID, Gigabit Ethernet, 4Gb Fibre Channel, 750W redundant power supplies, U320 SCSI, and 80GB and 1TB 7200 rpm SATA or 73GB or 300GB 15,000rpm SAS Apple Drive Modules. (Whew, that was a mouthful.) Check out all these dirty details and more on the Tech Specs page.
