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.

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.
