Figure 2. Supported Drive Combinations
RAID
The xw9300 supports SCSI RAID with the addition of a PP574AV card. That card supports RAID 0
(Striping, for performance) and RAID 1 (Mirroring for fault tolerance). The supported RAID
configurations require two or four SCSI drives, and in all cases disks being RAIDed must be identical.
Also note that using RAID 1 halves the amount of available storage. More details on the personal
Workstation RAID solutions can be found in the Personal Workstation RAID Solutions white paper.
Cabling
For Factory-integrated storage, all required cabling is provided. For xw9300 AMO storage, the
AA818A 5-Port SCSI cable should be ordered with the PP574AV RAID controller. The AA658A
U320 SCSI Back Panel cable kit allows external SCSI devices to be connected. For those customers
who desire to install their own EIDE drive(s) the DY660A EIDE Cable Kit is provided as an AMO item.
Summary
The xw9300 provides a large amount of highly-configurable storage.
