Drivers
The PowerEdge Expandable RAID Controller 2 (also called the RAID
controller) is a high-performance, intelligent PCI-to-SCSI host adapter with RAID
controller capabilities. The RAID controller has four SCSI channels that support
Fast, Wide, Ultra and Ultra2Wide SCSI at data transfer rates up to 80 MB/sec per channel.
Each SCSI channel supports up to 15 Wide devices.
PERC 2 Self-Monitoring Analysis and Reporting Technology (SMART)
capability detects up to 70% of all predictable drive failures. SMART monitors the
internal performance of all motors, heads, and drive electronics.
Configuration-On-Disk
Configuration-On-Disk (drive-roaming) saves configuration information on
the attached disk drive devices. If the RAID controller is replaced, the new RAID
controller can detect the actual RAID configuration, maintaining the integrity of the data
on each drive, even if the drives have changed channel and/or target ID.
