  • Page 15: Chapter 1. Reference Information

    Chapter 1. Reference Information The 7133 Serial Storage Architecture (SSA) Disk Subsystems can be attached to reduced instruction-set computer (RISC) systems. Models 010 and 020 1 are rack-mounted units that can be installed in a standard Electrical Industries Association (EIA) 19-inch rack. Models 500 and 600 2 are deskside units.

  • Page 16: Ssa Loops And Links

    SSA Loops and Links The disk drive modules of the 7133 are connected through two or more SSA links to an SSA adapter that is located in the using system. The disk drive modules, SSA links, and SSA adapter are configured in loops. Each loop provides a data path that starts at one connector of the SSA adapter and passes through a link (external SSA cable) to the disk drive modules.

  • Page 17: Lights And Power Switch

    Lights and Power Switch The 7133 has lights that show the status of the subsystem. It also has a power switch. Each disk drive module has lights that show the status of that module. Subsystem Lights and Power Switch Unless otherwise stated, the lights described in this section remain visible when the covers of the 7133 are installed.

    SSA Bypass Cards (Models 020 and 600) The four bypass cards that are at the back of the 7133 Models 020 and 600 provide the connections between the external SSA cables and the disk drive module strings. Each bypass card has two external SSA connectors. Through these connectors, the bypass cards and, therefore, the disk drive module strings, can be connected to each other or to the using system.
