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
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
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.
