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 PATA-
to-SATA adapters available from Promise Technology. The VTrak 15200 can
support up to fifteen disk drives and provide the RAID configurations listed below.
See page 189 for a complete explanation of RAID on VTrak.
