11.2 Dual port support

Pulsar XT.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 XT.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.
