SCSI BOARD
SCSI configurations come with an Adaptec 2940UW Ultra Wide SCSI adapter board
installed in a PCI expansion slot. The SCSI adapter board brings the highest performance
SCSI I/O technology to the PCI local bus, transferring data up to 133 MB/second. The
SCSI adapter board is compatible with all major operating systems, SCSI-1, SCSI-2 and
SCSI-3 peripherals, and industry-standard application software.
The BIOS-resident SCSISelect configuration utility eliminates the need to handle jumpers
or terminators while adding peripherals. All configuration and terminator settings are
controlled via the keyboard (see “SCSISelect Utility” in Section 2). The SCSI adapter
board includes the following features:
PCI to UltraSCSI host adapter with SCSISelect, utilizing the PCI local-bus to
support up to fifteen SCSI devices
Bus master DMA interface protocol
32-bit bus width
Up to 133 MB/second host bus burst data rate
Fast and wide 40 MB/second SCSI synchronous data rate
3.3 MB/second SCSI asynchronous data rate
