  • Page 15: Chapter 1: Introduction To The S-2500B

    Of the various choices of optical data transport, SONET offers a number of clear advantages for extending an FC-based SAN. The LightSand S-2500B Gateway has been optimized to make full use of these advantages for extending storage area networking.

  • Page 16: Sonet

    Credit buffering is a vital aspect of traffic control in a FC-based SAN. As distance (one component of latency) is added to the system, credit buffering becomes an even more crucial aspect of system design to guarantee that data is never dropped due to congestion. S-2500B Gateway...

  • Page 17: Ip Over Sonet

    TCP retransmission. In the critical area of buffer design, the S-2500B Gateway buffers are sized to store an amount of data equivalent to the need created if full latency is experienced over a full-rate link. Full rate transmission for the S-2500B can be sustained for up to 2000 km.

  • Page 18: Overview Of The S-2500B Gateway

    Overview of the S-2500B Gateway One S-2500B Gateway connects all of the FC switches in one SAN island to another SAN island. The physical interfaces are SONET (OC-48), Gigabit Ethernet (GbE) and/or Fibre Channel (FC). Each LightSand S-2500B Gateway is shipped with a set of control software pre- installed, including the CLI (Command Line Interface).

  • Page 19: Point To Point Topology

    IEEE 802.3z. Point to Point Topology Two S-2500B Gateways are directly connected via a SONET network in a point-to-point connection. This topology provides the highest performance, since the full bandwidth of the SONET link is dedicated to the Gateway SAN extension.

    CHAPTER 2 System Description Ports and Indicators The diagram below shows the ports and LED indicators on the back panel of the LightSand S-2500B Gateway. All optical ports use duplex connectors. FC / GbE Ethernet indicators Figure 2-1: S-2500B Back Panel...

  • Page 24: Graphical User Interface

    Networking and Connections Overview The LightSand S-2500B Gateway has been designed to support connections with wide area, local area and storage area networks, and well as serial connection to a console. The following describes a typical configuration of the S-2500B Gateway’s ports: •...

  • Page 26: Fc Connection

    FC Connection In the simplest configuration the S-2500B is connected through an FC port to a fibre channel switch, which in turn is connected to devices in a storage area network. The WAN port is used for a SONET connection to a remote gateway. The serial port supports direct communication with the gateway from a console.

  • Page 27: Fc And Gbe Connections

    FC and GbE Connections This configuration is similar to the FC connection described above, but adds a connection to a Gigabit Ethernet switch, which in turn connects to the LAN. Figure 2-4: S-2500B with GbE and FC Connections System Description...

  • Page 30: Gateway Setup Procedure

    A Quick Start Guide has been included at the beginning of this manual for those familiar with the operation of the S-2500B Gateway. After a new S-2500B Gateway has been installed it must be assigned an IP address so that it can be accessed over the LAN. The assignment is made using the CLI (Command Line Interface) over a serial link.
  • Page 31 At the prompt (“gateway:>” or the gateway’s name, if it has already been configured), enter the command to display the current data for the system: gateway:> show system info Example response (note that the IP address is blank): Name gateway Description : LightSand Gateway IP Address Net Mask Type S-2500B Location Milpitas...

  • Page 32: Configuring The Ports

    Connect the gateway to the LAN by plugging an Ethernet cable into the LAN Ethernet port (labeled “1”) on the back panel of the S-2500B. To reboot the S-2500B with a “cold” restart, use the command: config system restart cold.

  • Page 33: Establishing A Point To Point Connection

    The only type of TP currently supported is Packet Over SONET (POS). The S-2500B Gateway supports only one POS TP on the SONET port. Create a channel (a point to point connection) between the new node and another gateway using the example below as a guide.

  • Page 34: Creating A Redundant Pair

    Creating a Redundant Pair To prevent loss of service due to equipment failure, two S-2500B Gateways can be linked as a redundant pair using the LightSand Gateway Redundancy Protocol (LGRP). For a complete discussion of LGRP redundant pairs, please refer to Appendix B: Redundancy.

  • Page 35: Configuration For In-Band Management

    Configuration for In-Band Management In-band management refers to controlling one S-155B from another through the WAN (SONET or SDH) link between the two gateways. In-band management requires IP traffic to be carried over the WAN link. This might be necessary when, for example, the remote gateway is not connected to the Internet for security reasons and therefore cannot be controlled from a workstation over the Internet.

  • Page 36: Running The Sanman Gui

    SANman User Guide. Monitoring and Performance LED Indicators There are seven LED indicators on the back panel of the S-2500B which can be used to monitor the system status. Figure 3-1 below shows the back panel label. The LED meanings are further described on the following page.

  • Page 37: Fault And Performance Monitoring Using The Gui

    • Alarm: amber means at least one alarm is present of critical or major severity; off means no significant alarms are present. • SONET Link/Act: on means the SONET link is enabled; off means disabled. • ON = FC, OFF = GbE: left to right for Ports 1, 2, 3. On means the port is configured for FC, off means it is configured for GbE.
