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.
