11.0INTERFACE REQUIREMENTS

This section partially describes the interface requirements as implemented on Pulsar.2 drives. Additional information is provided in the SAS Interface Manual (part number 100293071).

11.1SAS FEATURES

This section lists the SAS-specific features supported by Pulsar.2 drives.

11.1.1Task management functions

Table 14 lists the SAS task management functions supported.

FUNCTION NAME	RESPONSE CODE

Function complete	00

Invalid frame	02

Function not supported	04

Function failed	05

Function succeeded	08

Invalid logical unit	09

11.2DUAL PORT SUPPORT

Pulsar.2 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 6Gb/s or the first port can run at 6Gb/s while the second port runs at 3Gb/s.) The supported link rates are 1.5, 3.0, or 6.0 Gb/s.

Subject to buffer availability, the Pulsar.2 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.
