2.7. PCI 3-Channel Ultra SCSI RAID Adapter (MSCG045)
Discontinued: 31/10/2000.
The PCI 3-Channel Ultra SCSI RAID Adapter is a non-bootable high performance Ultra SCSI RAID
Adapter providing RAID 0,1,or 5 capability and can address up to forty-five 16-bit SCSI-2 physical
disk drives on three independent SCSI buses. To increase the data writing performance, a 32 MB fast-
write cache is provided as a resident part of this adapter. The 32 MB fast-write cache is a resident
feature of the PCI 3-Channel Ultra SCSI RAID Adapter that utilizes non-volatile RAM.
