Chapter 1: Introduction
Thank you for purchasing Promise Technology’s UltraTrak SX4000, UltraTrak
SX8000 or UltraTrak RM8000 external disk array system.
UltraTrak provides data storage solutions for applications where fault tolerance
and data redundancy are required. The failure of any single drive will not affect
data integrity or accessibility of the data. A defective drive may be replaced
without interruption of data availability to the host computer. A hot spare drive will
automatically replace a failed drive, securing the fault tolerant integrity of the
array. The self-contained hardware-based array provides maximum performance
in a compact external chassis.
The UltraTrak SX4000 is an external disk array with an expandable capacity of
up to four individual disk drives. The UltraTrak SX8000 and RM8000 are external
disk arrays with an expandable capacity of up to eight individual disk drives.
The standard LVD SCSI interface provides compatibility with any system that
utilizes a SCSI interface.
Architectural Description
The UltraTrak disk array consists of either four ( SX4000 ) or eight
( SX8000/RM8000 ) disk drive bays, an enclosure with back plane, and the array
controller. Multiple fans provide redundancy to ensure continued usage should a
component fail. The array controller is hardware based and controls all array
functions transparently to the host system. It appears to the system as a standard
SCSI drive, and therefore does not require any special software drivers.
Warning
The electronic components within the UltraTrak disk array are sensitive
to damage from ESD (Electro-Static Discharge). Appropriate precautions
should be observed at all times when handling the array or its
subassemblies.
