NTERFACE REQUIREMENTS 

This section partially describes the interface requirements as implemented on Cheetah 15K.7 drives. Additional information 
is provided in the 

SAS Interface Manual

 (part number 100293071).

11.1

SAS 

FEATURES

This section lists the SAS-specific features supported by Cheetah 15K.7 drives.

11.1.1  task management functions

Table 7 lists the SAS task management functions supported.

11.1.2  task management responses

Table 8 lists the SAS response codes returned for task management functions supported.

11.2

UAL PORT SUPPORT

Cheetah 15K.7 SAS drives have two independent ports. These ports may be connected in the same or different SCSI 
domains. Each drive port has a unique SAS address.

The two ports have the capability of independent port clocking (e.g. both ports can run at 6Gbit/sec or the first port can run at 
6Gbit/sec while the second port runs at 3Gbit/sec.) The supported link rates are 1.5, 3.0, or 6.0 Gbits/sec.

Subject to buffer availability, the Cheetah 15K.7 drives support:

• Concurrent port transfers—The drive supports receiving COMMAND, TASK management transfers on both ports at the 

same time.

Full duplex—The drive supports sending XFER_RDY, DATA and RESPONSE transfers while receiving frames on both ports.
