Savvio 15K.2 SAS Product Manual, Rev. E 47
12.2 Dual port support
Savvio 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 Savvio 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.
