UltraSCSI Configuration Rules

Operating the UltraSCSI
Setting up an UltraSCSI RAID subsystem for operation involves
implementing the procedures described in the system-specific
"Getting Started" manual provided with each system. This chapter
supplements and expands on this information.
Other chapters in this manual contain detailed information about
individual component functions, operations, error conditions, and so
forth.
Proper operation of the subsystem requires complying with both the
UltraSCSI and hardware configuration rules. In some instances,
operating system-specific configuration rules might apply.

General

The following rules apply to the UltraSCSI bus:
The UltraSCSI RAID subsystems can transfer data at a higher
rate (40 MB/s versus 20 MB/s) than that of the FAST 10
subsystems.
UltraSCSI subsystems require 68-pin VHDCI cables and
connectors. The physical difference in the contact spacing
precludes using FAST 10 cables.
