1.1 SSA
SSA is a high-performance serial-interconnect technology used to connect I/O devices and host adapters. SSA is an open
standard, and SSA specifications have been approved by the SSA Industry Association and are in the process of being approved as
an ANSI standard through the ANSI X3T10.1 subcommittee. SSA retains the SCSI-2 commands, queuing model, status, and sense
bytes.
In SSA subsystems, transmissions to several destinations are multiplexed; the effective bandwidth is further increased by spatial
reuse of the individual links. Commands are forwarded automatically from device to device along a loop until the target device is
reached. Multiple commands can be travelling around the loop simultaneously.
