1 Introduction
The HP StoreEver 3U Rack-mount Enclosure is a rack-mountable storage system capable of holding
up to two full-height or four half-height drives. It is compatible with the 10000, 11000, and
Intelligent Series racks.

Standard Features
Standard features of the 3U rack-mount enclosure:
• 3U chassis supports two full-height or four half-height drives (or a combination of both full-height
and half-height drives)
• Top access panel and drive trays for easy access and deployment of drives
• Supports two full-height SCSI drives or four half-height SCSI drives (four SCSI buses are installed
in the 3U rack-mount enclosure)
• Supports two full-height SAS drives or four half-height SAS drives
• Power indicator on the front panel
• Three-year parts warranty
• 200-Watt Wide Ranging Input power supply
• Cable management
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: High quality external SAS cables rated at the transfer rate of the drive are required.
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 http://www.hp.com/storage/SPOCK for recommended cables.
