and global business continuity solu- tions. This extended distance connec- tivity can help create consolidated remote tape vaulting data protection plus metro mirror and global mirror disk-based disaster tolerant solutions.

High performance

The IBM System Storage SAN04B-R multiprotocol router is designed to deliver 4, 2 and 1 Gigabit per second (Gbps) full-duplex Fibre Channel or

50 Megabit per second Ethernet line- rate performance on all ports. Each router FC port auto-negotiates to 4 or

2 or 1 Gbps depending on the speed of the device at the other end of the link. The Ethernet ports enable reliable SAN extension across the Internet, IP-based Metropolitan Area Networks (MANs) and Wide Area Networks (WANs) through the use of Fast Write, hardware-based compression and storage-optimized protocol enhancements.

High-availability features

Mid-size SAN users require high- availability fabric solutions. The

IBM System Storage SAN04B-R multi- protocol router uses second-generation advanced application-specific inte- grated circuits (ASIC) electronic compo- nents to help minimize the number of

components and improve reliability. The SAN04B-R router is designed to pro- vide hot-swappable, load-sharing dual redundant power supplies that allow the router to remain online if one power supply fails. Dual power cords allow attachment to separate power sources for improved availability. Hot-swappable power supplies and redundant cooling fans help eliminate downtime for service when replacing a failed component. Hot-pluggable SFP transceivers are designed to be replaced without taking the router offline.

High availability solutions require redun- dant components, including clustered servers with dual Host Bus Adapters, dual independent fabrics and disk stor- age arrays with dual controllers each with dual adapters. Dual IBM System Storage SAN04B-R routers may be configured in a high availability solution to create a resilient “meta” SAN infrastructure.

Configuration flexibility

A variety of SFP transceivers are avail- able to meet diverse requirements. Standard short wave optical Fibre Channel SFPs are available to connect at distances up to 1500 meters. Long wave optical Fibre Channel SFPs are

available to connect at distances of up to 4 km, 10 km or 30 km. Optical SFPs are always used to connect the FC ports to a Fibre Channel fabric, how- ever both optical and copper SFPs are available to connect the Ethernet ports to an Ethernet fabric.

The router helps provide full Fibre Channel fabric services with many stan- dard features including WEBTOOLS with Advanced Zoning, FCIP Tunneling Service and Extended Fabric.

Fabric Operating System

Brocade® Fabric OS® (FOS) is included with each SAN04B-R and contains all functions necessary to operate a base system. The SAN04B-R requires FOS level 6.1.0 or higher. FOS offers the following advanced functions:

●ADVANCED PERFORMANCE MONI- TOR helps identify end-to-end

bandwidth usage by host/target pairs and is designed to provide for capacity planning.

●TRUNKING enables FC packets to be efficiently distributed across multi- ple ISLs between two IBM SAN b-type fabric switches and directors while preserving in-order delivery. Both SAN b-type devices must have trunking activated.
