  • Page 11: Chapter 1. Introducing The Ssa Raid Adapter

    Introducing the SSA RAID Adapter The IBM SSA RAID Adapter for PC Servers is a PCI bus-master adapter that serves as the interface between systems using the Peripheral Component Interconnect (PCI) architecture and devices using the Serial Storage Architecture (SSA). The SSA RAID Adapter provides RAID functions.
  • Page 12 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. _ Copyright IBM Corp. 1996 1.1 - 1...
