  • Page 14: Overview

    Overview The Hewlett-Packard SureStore E hub, short-wave model S10 and long-wave model L10, is a full-duplex, 1063-megabit-per-second hub. It increases loop reliability, number of loop connections, and distances between server and mass storage devices in a Fibre Channel Arbitrated Loop. The hub’ s port detection and bypass circuitry dynamically detects and bypasses a failed node on the loop.

  • Page 21: Cascaded Long-wave Hub Topology, Example Topology: Cascaded Long-wave Hubs

    Cascaded Long-Wave Hub Topology Cascaded FC-AL, non-OFC, model L10 long-wave hubs use the long-wave port for the hub- to-hub connection. The maximum supported distance between cascaded long-wave hubs with single-mode 9 micron cable is 3 km. The maximum distance between a server and FC- AL devices on cascaded long-wave hubs is, therefore, 4000 meters (500 m + 3000 m + 500 m).

  • Page 22

    Cascaded hubs must have the same firmware versions to operate properly. If you are using Fibre Channel Manager to manage cascaded hubs, configure the hub that has the LAN (ethernet) connection as a parent hub and the remaining hub as a child hub (see page 60 for more information).

    Laser Safety A. Certification and Classification Information This product contains a laser internal to the Optical Link Module (OLM) for connection to the Fibre communications port. In the USA, all models of the OLM are certified as Class 1 laser product and conform to the requirements contained in the Department of Health and Human Services (DHHS) regulation 21 CFR Subchapter J.

  • Page 116

    B. Product Information Each communications port consists of a transmitter and receiver optical subassembly. The transmitter subassembly contains internally a semiconductor laser diode in the wavelength range of 780 to 1300 nanometers. In the event of a break anywhere in the fibre path, the OLM control system prevents laser emissions from exceeding Class 1 levels.

    The HP SureStore E short-wave and long-wave hubs support a cascaded topology. In a cascaded hub topology, the child hub is the hub that is not connected to the LAN (ethernet). HP SureStore E hubs are configured as a parent or child hub through their RS-232 interface.

    Fibre Channel Logically, Fibre Channel is a bidirectional, full-duplex, point-to-point, serial data channel structured for high performance capability. Physically, the Fibre Channel is an interconnection of multiple communication ports, called NL_Ports, interconnected by a switching network, called a fabric, a point-to-point link or an arbitrated loop. Fibre Channel is a generalized transport mechanism that has no protocol of its own or native input/output command set, but can transport any existing Upper Level Protocols (ULPs) such as SCSI and IPI at speeds of 100 Mbytes/sec over distances of up to 10...
