  • Page 15: Chapter 1: Introduction

    This section provides a brief introduction to storage networks, and shows how the GigaSAN Bridge fits into this architecture. Traditional Storage Architecture Traditionally, storage has been attached directly to each application server.

  • Page 16: Storage Networks

    SCSI or FC storage to your network. And for companies that have already installed an FC SAN, the GigaSAN Bridge can be used to link existing FC resources to new storage farms or remote sites over Gigabit Ethernet.

  • Page 17: Storage Client

    Management Port Gigabit Ethernet Ports The GigaSAN Bridge provides dual Gigabit ports for attaching the bridge to the storage network with a trunked connection. Both speed and failover protection are critical elements for any storage network. These dual ports allow you to increase bandwidth up to 4 Gbps for a full-duplex connection, while at the same time providing failover in case one of the links (or ports) should fail.

  • Page 18: Scsi Ports

    Standard SCSI). FC Ports The GigaSAN Bridge includes a slot on the rear panel for an optional FC adapter. Using an arbitrated loop, you can connect up to 127 storage devices to an FC port. The GigaSAN Bridge automatically scans for new FC devices each time it boots up, and automatically detects the speed, frame size, and device ID.

    Web browser, Telnet, or SNMP software. Service Port The GigaSAN Bridge contains a console port on the rear panel that provides limited access to key configuration commands and system status information. This is an RS-232 serial port with a DB-9 connector. A PC may be connected to this port for system diagnostics and monitoring via a null modem cable.

  • Page 21: Supported Platforms

    Supported Platforms Supported Platforms You can connect a client directly to the GigaSAN Bridge or indirectly through a switch or router. The GigaSAN Bridge provides storage configuration software for both the server (embedded in the bridge) and client. Client software is currently available for Windows NT/2000, Linux, Solaris, HP-UX, and AIX.

  • Page 23: Chapter 2: Network Planning

    Chapter 2: Network Planning Introduction to Storage Networks The GigaSAN Bridge provides the key to building a dedicated storage network with off-the-shelf industry-standard components, such as Gigabit Ethernet switches and adapter cards. Using a separate storage network frees up your corporate network for critical applications.

  • Page 24: Storage Area Networks

    As shown in the following figure, the GigaSAN Bridge can allocate virtual storage to either NAS or SAN clients. This allows you to consolidate application servers in a server farm and dynamically manage the required storage space.

  • Page 25: Remote Operations

    Data kept on storage media must be backed up or mirrored to avoid loss due to equipment failure, or to facilitate easy access to common databases from multiple sites. The GigaSAN Bridge moves data over standard IP protocol to simplify storage management both for both local and remote operations.

  • Page 26: Redundancy Protection

    To provide fully redundant links between data storage and your server, you should install dual storage network cards in the server and configure them as a trunked link. Application Clients Corporate Network Storage Network GigaSAN Bridge AN Bridge GigaS Activity et Port Fail...

  • Page 27: Protocol Architecture

    Because of the expense and complexity of Fibre Channel, future SANs will mostly be based on IP networks. The GigaSAN Bridge supports a method of passing native SCSI commands over modified UDP (referred to as SAN/IP), as well as the iSCSI protocol that runs over more reliable IP networks.
