5742-8204 - IBM i Model E8A IBM Dual Bus Ultra 320 SCSI Repeater
IBM i Power 6, 8204 (#5742) IBM Dual Bus Ultra 320 SCSI Repeater Card
(Refurbished Condition Only as of November 26, 2010)
The Dual Bus Ultra 320 SCSI repeater card provides the paths to transmit the differential SCSI signal from a cable to the DASD backplanes contained in the IBM 7031 Model D24 Ultra 320 Expandable Disk Storage Drawer or the #5786 TotalStorage EXP24 Disk Drawer. This high availability dual initiator feature allows the connection of two adapter cards to a SCSI group. The high availability SCSI connection feature can be used on any or all of the drive groups in the 7031 Model D24 and feature #5786 in conjunction with other drive groups in the enclosure using the standard IBM Single Bus Ultra 320 SCSI Repeater Card (FC #5741). The Dual repeater option can also be used to connect all 12 of the front drives or all 12 of the rear drives into a single SCSI bus of 12 drives.
The Ultra 320 SCSI Repeater Card provides the following functions:
Provide SCSI enclosure services for all disk drives
Read power supply unit Vital Product Data ( VPD)
Monitor power line voltage EPOW (Early Power Off Warning) signals from the power supplies and assert SCSI reset to prevent data corruption during power failures.
Detect hot plugged disk drives and power them on on automatically
Separate power partitions to each individual drive preventing cage power faults for a single drive fault
Provide cage power on commands when any attached host adapter is active
Redrive the SCSI bus to allow SCSI cable lengths up to 20 meters
Provide SCSI bus terminations for host and drve busses
