Overview
The HP StorageWorks Disk System 2120 is a 1-EIA unit disk systems capable of
accommodating up to four disk modules. It is designed to provide inexpensive, high
performance rack-optimized online mass storage for entry-level configurations in
three distinct markets: (1) HP servers/workstations, (2) open systems JBODs, and (3)
open systems IDACs (Internal Disk Array Controller).
The DS2120 supports U320 drives; however, the U320 drives are supported at a
maximum of 160 MB/s speeds.
Connectivity to U320 initiators is supported if the speed of the U320 initiator is set to
limit negotiations to U160 speed. The U320 drives do not operate reliably or at
acceptable performance levels at U320 speeds and are not supported at those speeds.
This is due to limitations within the disk system and not the U320 drive mechanisms.
