• Fabric Watch-Proactively monitors the health and performance of switches and the fabric. • ISL Trunking-Combines multiple links between switches to form a single, logical ISL with a total bandwidth of 64 Gb/s. This feature enables dynamic load balancing of data across ISLs. • FCIP Trunking-Allows multiple IP source and destination address pairs (defined as FCIP circuits) via multiples of the 1 GbE or 10 GbE interfaces to provide a high-bandwidth FCIP tunnel and failover resiliency. FCIP tunnels using 1 GbE ports can have up to four FCIP circuits spread over four 1 GbE ports. FCIP tunnels using 10 GbE ports can have up to ten FCIP circuits per 10 GbE port. Each FCIP circuit supports four QoS classes as a TCP connection (Class-F, Hi, Medium and Low priority). NOTE: FCIP Trunking is supported only on the 1606 Extension SAN Switch and the DC Dir Switch MP Extension Blade. For more information, see "B-series 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade" on page 312. • Adaptive Rate Limiting-Dynamically adjusts data transmission through the TCP connections in a FCIP tunnel, based on preconfigured minimum and maximum data rates and by taking feedback from the quality of the TCP connections. This allows FCIP connections to use the maximum bandwidth available while providing a minimum bandwidth guarantee. NOTE: ARL is supported for configuring FCIP tunnels only on the 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade. • NPIV -See "SAN fabric connectivity and switch interoperability rules" on page 167. The following B-series Fibre Channel switches are NPIV compliant: • 8 Gb/s: Brocade 8Gb SAN Switch for HP BladeSystem c-Class; SAN Switch 8/8, 8/24, 8/40, and 8/80; DC SAN Backbone Director; DC04 SAN Director; EVA4400 Embedded Switch Module; Encryption SAN Switch; and Encryption FC Blade • 4 Gb/s: 4/8, 4/16, 4/32, 4/32B, 4/64, and 4/256, Brocade 4Gb SAN Switch for HP nl c-Class BladeSystem; and Brocade 4Gb SAN Switch for HP p-Class BladeSystem • 2 Gb/s: 2/8V, 2/16V, 2/16N, 2/32, and 2/128 • Remote Switch-Creates one logical SAN that spans remote fabrics at unlimited distances. All SAN components appear as local devices. Remote Switch works in conjunction with a Fibre Channel gateway to connect two remote switches over an IP network, enabling communication of IP as well as Fibre Channel protocols. NOTE: You enable Remote Switch by issuing the portcfgislmode command for all switch models that use firmware 3.1 (or later), 4.x, 5.x, or 6.x. A license is required for switch models that use firmware 2.x. • Secure Fabric OS-Provides flexible security and policy-based administration to protect data from unauthorized access and corruption. All Secure Fabric OS features are included in the base Fabric OS beginning with 5.3.0 firmware. Secure Fabric OS can coexist in a fabric running Fabric OS 5.3.x firmware, but this is not supported with later versions of Fabric OS. SAN Design Reference Guide 101
