1-6 DAC960PG Installation Guide
RAID/SCSI Disk Array Management
• Supports multiple RAID levels (0, 1, 3, 5, and 0 + 1) allowing the
user to select the desired combination of storage capacity, data
availability (redundancy) and I/O transfer performance for any data
application
• Connects up to 45 SCSI drives that can be grouped and managed as
a single, large-capacity logical drive (up to 2 TeraBytes), as multiple
large-capacity drive groups, or as individual drives (with a
maximum of 32 system drives)
• Up to eight DAC960PG controllers per host connect up to 180 SCSI
devices
• Industry-standard Fast/Wide Ultra-SCSI interface supports most
SCSI drives
Automatic RAID Functions
• Automatic failed drive detection
• Automatic rebuild of the array using stand-by (hot spare) disk after a
drive failure
• Transparent drive rebuild permits automatic rebuild of failed drives
during normal operation without having to take the array off-line
• Automatic error detection/correction of parity errors, bad blocks,
etc.
• Automatic sector remapping recovers defective media and corrects
data errors
Automatic On-board SCSI Termination
• No jumpers to set
• Automatic internal and external bus detection on each channel
• On-board termination automatically enabled or disabled
• Improved ease of hardware configuration allows reconfiguration of
channels without removing DAC960PG from host
