Install Disk Drives
Before using the VTrak you must first populate it with Serial ATA (SATA) disk
drives. You can also use Parallel ATA (PATA) disk drives with the optional SATA-
to-PATA adapters available from Promise Technology. The VTrak 15110 can
support up to fifteen disk drives and provide the RAID configurations listed below.
See Chapter 7, page 207 for a complete explanation of RAID on VTrak.
Caution
Do not pull or push the handles on the Power Supplies or the
Controller units in order to move the VTrak. Hold the VTrak by the
housing only.
