The PCI SCSI-3 Ultra/Wide SE Adapter provides high performance attachment to both internal and
external Single Ended SCSI disks, disk subsystems, tape devices. The maximum data rate depends on
the maximum data rate of the attached devices.
The PCI SCSI-3 Ultra/Wide SE Adapter has one external connector (68p) and two internal connectors
(1 Narrow 50p and 1 Wide 68p). The Adapter is capable of addressing up to 15 Single Ended devices.
The number of physical devices attached is limited by SCSI bus cabling restrictions. The adapter
supports either 8-bit or 16-bit devices.

2.13. PCI SCSI-2 Fast/Wide SE Adapter - DPT (MSCG027)
Discontinued.
The PCI SCSI-2 Fast/Wide SE Adapter is a single ported fast (10 MHz) and wide (16-bit wide) SCSI
PCI Adapter that can provide synchronous SCSI bus data rates of up to 20 megabytes per second.
The PCI SCSI-2 Fast/Wide SE Adapter provides high performance attachment to external Single
Ended SCSI disks, disk subsystems, tape devices. The maximum data rate depends on the maximum
data rate of the attached devices.
The PCI SCSI-2 Fast/Wide SE Adapter has one external Single Ended port. The external port is
capable of addressing up to seven Single Ended devices. The number of physical devices attached is
limited by SCSI bus cabling restrictions. The external port of this adapter supports either 8-bit or 16-bit
devices via a 16-bit connector. The external Single Ended SCSI bus is capable of supporting cable
lengths of 4 meters.
This Adapter is used with the Escala S expansion disks cabinet.
