2.11. PCI Single-Ended Ultra SCSI Adapter (MSCG040 ; CKTG146)
The PCI Single-Ended Ultra SCSI Adapter is an ideal solution for applications requiring large block
data transfers (more than 64K block size) in a multi disk drive environment utilizing SCSI-2 protocol.
The PCI Single-Ended Ultra SCSI Adapter has a maximum data transfer rate of 40 MB per second,
which is twice the maximum data transfer rate of SCSI-2 Fast Wide adapters (20 MB per second).
The PCI Single-Ended Ultra SCSI Adapter conforms to the SCSI-2 standard and Fast-20 (Ultra)
specifications. Industry standard 68 pin connectors are incorporated (SCSI "P" connector definition of
X3T9.2/90-048).
Operational Requirements
•
Supported on the S100, S120, T610, PL400T and PL600T
•
One free PCI slot.
•
AIX 4.3 or later.
2.12. PCI SCSI-3 Ultra/Wide SE Adapter (MSCG022)
The PCI SCSI-3 Ultra/Wide SE Adapter is a single ported Ultra (20 MHz) and wide (16-bit wide)
SCSI PCI Adapter that can provide synchronous SCSI bus data rates of up to 40 megabytes per
second.
