CAUTION
High quality external SAS cables rated at the transfer rate of the tape
drive are required. Always verify the external SAS cable you are using is
rated for the data transfer speed of the interface of your components.
SAS cables described as "equalized" may not support 6 Gb/s data rates
and should not be used with LTO-5 tape drives unless these cables are
verified for 6 Gb/s data rates. For optimum performance, only use cables
of the length specified as qualified for your products. Refer to the
PRIMERGY's website for recommended cables.
The SAS interface board has two external ports and the supplied internal SAS
cable, illustrated below, 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.
