1 Introduction
The HP StoreEver 1U Rack-mount Enclosure is a rack-mountable storage system capable of holding
up to two half-height 5.25 inch tape or RDX disk drives. It is compatible with most standard 19
inch racks.

Standard Features
Standard features of the 1U rack-mount enclosure:
Supports one or two 5.25 inch half-height tape or RDX disk drives
Installation in standard 19 inch racks with round, square, or threaded holes
NOTE:
Daisy-chaining of two or more SCSI version 1U rack-mount enclosures is not supported.
Supported Controllers and HBAs
For up-to-date SCSI and SAS HBA compatibility information, review the compatibility matrix on
the Enterprise Backup Solutions website at: http://www.hp.com/storage/SPOCK.
NOTE:
SCSI drives: The SCSI bus type determines the speed at which data can be transferred
between devices on the bus and the maximum length of cable that can be used. LTO–3 and LTO–4
tape drives support a burst transfer rate of 320 MB/sec. LTO–2 tape drives support a burst transfer
rate of 160 MB/sec. To benefit from this level of performance, it is important to ensure that the
drives are connected to a SCSI bus of a similar or higher specification. LTO–3 and LTO–4 SCSI
drives should be on their own SCSI bus.
SAS Cabling Recommendations
CAUTION:
Always verify that the external SAS cable being used is rated for the data transfer speed of the
interface of your component. SAS cables described as "equalized" may not support 6 Gb/s data
rates and should not be used with LTO-5 or LTO-6 tape drives unless these cables are verified for
6 Gb/s data rates. For optimum performance, only use HP cables of the length specified as qualified
for your products. Refer to
The SAS interface board has two external ports illustrated below. The supplied internal SAS cable
supports connection of two devices. Several cabling configurations are possible, but the following
cabling configuration is recommended to provide the most consistent layout between devices and
external connectors.
Looking at the rack from the rear, the right-most external port is Port 1 and the left-most external
port is Port 2.

Introduction
High quality external SAS cables rated at the transfer rate of the drive are required.
