PE RC 3/ DC and PE RC 3/DC L Fe atures 65SMART TechnologyThe PERC 3/DC and PERC 3/DCL self-monitoring analysis and reportingtechnology (SMART) detects predictable drive failures. SMART monitorsthe internal performance of all motors, heads, and drive electronics.Configuration on DiskNOTE: Configuration onDisk does not work if youchange both the adapter,and the SCSI connectorsto different connectors onthe new adapter. It worksonly if you make onechange at a time.Configuration on Disk (drive roaming) saves configuration informationboth in NVRAM on PERC 3/DC and PERC 3/DCL and on the disk drivesattached to PERC 3/DC and PERC 3/DCL. If PERC 3/DC and PERC3/DCL are replaced, the new PERC 3/DC and PERC 3/DCL controllersdetect the actual RAID configuration, maintaining the integrity of the dataon each drive, even if the drives have changed channel and/or target ID.Drive roaming is supported across channels on the same controller. Driveroaming across channels is not supported when cluster mode is enabled.Table 5-2 shows the features for Configuration on Disk.Flashable firmware YesHot swap devices supported YesNon-disk devices supported NoMixed capacity hard disk drives YesNumber of 16-bit internal connectors 2Cluster support Yes (PERC 3/DC only)Ta b l e 5 - 1 .
