2.15. PCI SCSI-3 Ultra/Wide DE Adapter (MSCG023)
The PCI SCSI-3 Ultra/Wide DE 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.
The PCI SCSI-3 Ultra/Wide DE Adapter provides high performance attachment to external
Differential SCSI disks, disk subsystems, tape devices. The maximum data rate depends on the
maximum data rate of the attached devices.
