NTRODUCTION
Thank you for purchasing Promise Technology’s UltraTrak100 TX4 or
UltraTrak100 TX8 external disk array system.
UltraTrak100 TX8 external disk array system.
UltraTrak100 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 standard LVD SCSI interface provides compatibility with any system that
utilizes a SCSI interface. No vendor unique commands are required for the
operation of the disk array. Data transfer rates of up to 80 MB/sec are supported
via the SCSI interface.

ESCRIPTION
The UltraTrak100 disk array consists of either four (TX4) or eight (TX8) disk drive
bays, an enclosure with back plane, and the array controller. Multiple fans provide
redundancy to ensure continued usage during component failure. 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.

Attention
The electronic components within the UltraTrak100 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.
