  • Page 11: Introducing Remote Switch

    INTRODUCING REMOTE SWITCH The Remote Switch feature, in conjunction with a compatible fibre channel to asynchronous transfer mode (ATM) gateway, enables two fabric switches to be connected over an ATM connection, with a distance of up to 10 km between each switch and the respective ATM gateway. The two switches are cascaded together to form a fabric that, from the viewpoint of the connected hosts and storage devices, interact the same as locally connected switches.
  • Page 12 • Distributed management - Access to the management facilities (Web Tools, Telnet, and SNMP) is available from either the local or remote switch. Interconnect for switch management is routed through the fibre channel connection; no additional network connection is required between sites.

    INSTALLING REMOTE SWITCH A Remote Switch fabric requires two switches with Fabric OS version a2.4.1 or later installed; both the switches must have the same configuration and a separate license for each switch. The switch licenses are applied by your HP Account Support Engineer (ASE) or Customer Engineer (CE). You can also install a license through telnet or Web Tools.

  • Page 21: Introducing Extended Fabrics

    INTRODUCING EXTENDED FABRICS Extended Fabrics allows you to use fibre channel technology to create a fabric interconnected at a distance of up to 100 kilometers. You can use Extended Fabrics to increase the allowable distance between two switches, or between a switch and an ATM gateway in a Remote Switch configuration.

  • Page 23: Installing Extended Fabrics

    INSTALLING EXTENDED FABRICS Extended Fabrics requires a switch with Fabric OS version a2.4.1 installed and a license for each switch in the fabric. An Extended Fabrics license is installed on each switch by your HP Account Support Engineer (ASE) or Customer Engineer (CE).

    USING EXTENDED FABRICS You can configure ports to support long-distance links through Telnet or through Web Tools. For information about using Web Tools to configure ports, see the Web Tools User’s Guide. Configuring Extended Fabrics To use Extended Fabrics, you must configure each switch in the fabric to support a long-distance extended fabric.

  • Page 28: Accessing Through The Telnet Interface

    There are three possible levels for a port: • Level 0 Reconfigures the port as a regular switch port. The number of buffers reserved for the port supports up to 10 km links. • Level 1 Distances up to 50 km. A total of 27 full-size frame buffers are reserved for the port.
  • Page 29 When this command is invoked without the optional operand, you are prompted to enter the long-distance level number. The level value must be one of the following: Level Effect Reconfigures the port as a regular switch port. The number of buffers reserved for the port supports links up to 10 km.
  • Page 30 In order to have a long-distance port take effect, all switches in the fabric must be configured to run in long-distance fabric mode (the long-distance fabric mode bit must be “on,” or set to 1). Otherwise, the fabric will be segmented.

  • Page 31: Glossary

    GLOSSARY This glossary provides definitions for fibre channel and switch terminology. Alias Server A fabric software facility that supports multicast group management. AL_PA Arbitrated Loop Physical Address. An 8-bit value used to uniquely identify an individual port within a loop. A loop can have one or multiple AL_PAs. Arbitrated Loop Afibre channel transport structured as a loop.
  • Page 32 Credit When applied to a switch, the maximum number of receive buffers provided by an F_Port or FL_Port to its attached N_Port or NL_Port, respectively, such that the N_Port or NL_Port can transmit frames without over-running the F_Port or FL_Port. Defined The complete set of all zone objects that are defined in the fabric.
  • Page 33 FSPF Fibre-Channel Shortest Path First. A routing protocol used by fibre channel switches. G_Port A generic port that can operate as either an E_Port or an F_Port. A port is defined as a G_Port when it is not yet connected, or has not yet assumed a specific function in the fabric.
  • Page 34 POST Power on self-test. A series of self-tests that run each time the unit is booted or reset. R_A_TOV Resource Allocation Timeout Value. Used to time out operations that depend on the maximum possible time that a frame can be delayed in a fabric and still be delivered.
  • Page 35 Zone A set of hosts and devices attached to the same fabric and designated as belonging to the same zone. Any device connected to the fabric can be configured into one or more zones. Zone alias An alias for a set of port numbers or WWNs. Zone aliases can be used to simplify the entry of port numbers and WWNs.
