That looks like the Xserve RAID. It is going to be introduced at the end of the year. It is a companion product with 2Gbps Fibre Channel storage and 14 had drives.
Maccentral.com has the dirt on the RAID:
* 3U height
* 14 drive bays
* 14 120GB ATA drives - in same hot-plug format as Xserve
* 1.68TB
* Dual 2GB Fibre Channel on system
* 400MB/second storage throughput
Everything redundant: RAID controllers, power supplies, fans, drive caches and the drives drives themselves. Like the Xserve, each HD has a direct connection to their controller (7 HD's per controller).
Each RAID controller has 128MB of RAM. This thing looks like it kicks @$$!
must find reason for installing at home....
Actually, we have about 30 virtually new racks at work that are rusting in a warehouse. They are only 5 feet, but they are on pretty sturdy wheels. Now I have a reason to bring one home...
*sigh* - I gotta start playing the lotto.
