2. Disk Drive Adapters
2.1. PCI Dual Channel Ultra320 SCSI Adapter (MSCG054, MSCG060)
The PCI-X Dual Channel Ultra320 SCSI Adapter is a 64-bit 3.3 volt adapter which is an excellent
solution for high-performance SCSI applications. This adapter provide two SCSI channels (busses),
each capable of running 320 MBps (max.), up to twice the maximum data transfer rate of the previous
Dual Channel Ultra3 SCSI adapter (160 MBps). Each SCSI bus can either be internal or external.
Internally attached Ultra320 devices are designed to run at a data rate of up to 320 MB per second on
systems that have internal backplanes that are capable of supporting Ultra320 speeds.
Operational Requirements
•
Supported on the PL220T, PL240T and PL420T.
•
One free PCI slot.
•
MSCG054: AIX 5.1 or later for PL240T and PL420T
•
MSCG060: AIX 5.1 or later for PL220T
2.2. PCI 4-Channel Ultra320 SCSI RAID Adapter (MSCG053, MSCG059)
The PCI-X Dual Channel Ultra320 SCSI RAID Adapter is a 64-bit 3.3 volt, bootable high
performance adapter with a data rate of up to 320 MB per second and provides RAID 0,5, or 10
capability that can address up to thirty 16-bit SCSI physical disk drives on two independent SCSI
buses. A 40 MByte fast-write cache is resident on the adapter and is designed to increase the data
writing performance.
Operational Requirements
•
Supported on the PL220T, PL240T and PL420T.
•
One free PCI slot.
•
MSCG053: AIX 5.1, or later for PL240T and PL420T.
•
MSCG059: AIX 5.1, or later for PL220T
2.3. Dual Channel Ultra320 SCSI RAID Enablement Card (MSCG052)
The Dual Channel SCSI RAID Enablement Card is a bootable high performance SCSI RAID
Enablement feature providing RAID 0,5, or 10 capability to select pSeries systems with the
appropriate supporting integrated SCSI adapter. The enablement card provides an internal RAID
solution on supporting pSeries systems with internal multiple disk drives or packs of drives
