1.2.4 Ultra SCSI

The LSI8751D has full support for Ultra SCSI and simultaneously

supports Fast SCSI. Ultra SCSI is an extension of the SCSI-3 family of

standards that expands the bandwidth of the SCSI bus, allowing faster

synchronous data transfers. Special SCSI cables are speciﬁed for

operation with Ultra SCSI devices, and you must consider the total

number of devices and the length of your SCSI bus when setting up your

system. See Section 1.2.3, “Connecting the SCSI Peripherals,” page 1-5

for a more detailed explanation of SCSI bus connections.
