Features

Brocade and IBM are delivering innovative and powerful IT infrastructure for virtual data centers based on best-in-class, industry-standard computing and networking technology. Brocade 8Gb SAN Switch Modules for IBM BladeCenter support entry-level to enterprise SAN I/O requirements for next-generation data centers.

The Brocade switch modules include the following hardware features:
  • Six external auto-sensing Fibre Channel ports (2 Gbps, 4 Gbps, or 8 Gbps for 8Gb SFP+ transceivers) that operate at a maximum speed of 8 Gbps
  • 14 internal Fibre Channel ports that operate as F_ports (fabric ports) at 2 Gbps, 4 Gbps, or 8 Gbps, depending on FC expansion cards installed into blades
  • 10-port model includes 10 Dynamic Ports-On-Demand (DPODs) that can be activated in any combination of internal and external ports
  • High availability features including hot pluggable design, non-disruptive software upgrades, automatic path failover, and power-on self-test diagnostics and status reporting
  • Aggregate Fibre Channel I/O bandwidth: 48 Gbps (6 external ports at 8 Gbps line rate)
  • External ports that can operate as F_ports (fabric ports), FL_ports (fabric loop ports), or E_ports (expansion ports) when in full FC switch mode. When in Brocade Access Gateway mode the external ports operate as NPIV-enabled N_Ports.
  • Fabric latency of 0.74 μsec ensures the fastest response and access time to data for critical applications and servers
  • Supports full 8 Gbps operations at distances up to 129 km and up to 1036 km at 1 Gbps


Brocade switch modules include the following software features:
  • Brocade Full Fabric mode: Enables high performance 8Gb fabric switching
  • Brocade Access Gateway mode: Leverages NPIV to connect to any fabric without adding switch domains to reduce management complexity
  • Dynamic Path Selection: Enables exchange-based load balancing across multiple Inter-Switch Links (ISLs) for superior performance
  • Brocade Advanced Zoning: Segments a SAN into virtual private SANs to increase security and availability
  • Brocade Enhanced Group Management: Enables centralized and simplified management of Brocade fabrics through IBM System Storage Data Center Fabric Manager (DCFM)


Brocade switch modules support the following fabric management (all management connections go through the management module):
  • IBM System Storage DCFM: Centralizes and simplifies management of enterprise level SAN fabrics consisting of IBM System Storage b-type (using FOS) and Brocade fabrics m-type (using M-EOS) SAN products
  • IBM System Storage DCFM Professional Plus: For customers managing single fabrics up to 1000 ports running Brocade Fabric OS (FOS) products
  • Brocade Web Tools: Provides Web-based management interface designed to help simplify monitoring and configuration management
  • Command-line interface (CLI) through the Telnet program
  • Switch SNMP agent, which enables receipt of configuration values, traffic information, and FC failure data through SNMP and the Ethernet interface


The Enterprise 20-port model (42C1828) is a fully enabled switch with a complete set of licensed features that maximizes performance, ensures availability and simplifies management for the most demanding applications and expanding virtualization environments. The factory-installed licenses include:
  • ISL Trunking: Consolidates ISLs into fault-tolerant and load balanced trunks with bandwidth of up to 48 Gbps for greater performance and simplified management
  • Adaptive Networking: Ensures high priority connections obtain the bandwidth necessary for optimum performance
  • Advanced Performance Monitoring: Provides end-to-end visibility into fabric performance to maximize performance tuning and the utilization of fabric resources
  • Fabric Watch: Monitors and creates alerts based on the health of switch and fabric elements
  • Extended Fabrics: Extends Fibre Channel SANs beyond traditional distance limitations for replication and backup
  • Server Application Optimization: Allows Virtual Machine Quality of Service (QoS), authentication and monitoring from adapter through SAN


The following optional software features are available for the 10-port and 20-port modules. These features are factory installed on the Enterprise 20-port module (42C1828).
  • 10-Port Port-on-Demand upgrade for 10-port model (32R1822)
  • ISL Trunking (26K5607)
  • Advanced Performance Monitoring (45W0508)
  • Extended Fabrics (45W0505)
  • Fabric Watch (45W0504)
  • Adaptive Networking (45W0510)

Note: Server Application Optimization is not available for the 10-port and 20-port modules.

Connectors and LEDs

The front panel of the Brocade 8Gb SAN Switch Module contains the following components, as shown in Figure 4:
  • Information LEDs that display the status of the I/O module and its network connections.
  • Six external Fibre Channel ports to connect Fibre Channel devices and switches. These ports are labeled 0, 15, 16, 17, 18, and 19 (from top to bottom) on the I/O module.

Table 7 lists the LEDs on the front panel and their meanings.

Table 7. LEDs on the front panel
LED nameLED description
System Status (OK)This green LED is at the top left of the I/O module on the front panel and indicates that the module is working properly.
System Status (!) (I/O module fault)This amber LED is at the top right of the I/O module on the front panel. This LED indicates that the I/O module has a fault. If the I/O module fails the POST, this fault LED is lit.
External port status (TX/RX)There are six green external port activity (TX/RX) LEDs. When one of these LEDs flashes, it indicates that data is being received or transmitted (that is, activity is occurring) on that port. The flash frequency is proportional to the amount of traffic on that port.
External port diagnostics (!)There are six amber external port fault (!) LEDs. When an external port fault LED is lit, it indicates that the external port has failed the internal, external, or online port diagnostics tests.

Operating environment

The environment has the following temperature and altitude requirements:
  • Operating:
    • 10 - 52 °C (50 - 125 °F) at an altitude of 0 to 914 m (0 to 3,000 ft)

  • Non-operating:
    • - 40 - 65 °C (-40 - 149 °F) at an altitude of 0 to 12,000 m (0 to 39,370 ft)

The environment has the following humidity level requirements:
  • Operating: 8% to 80%, noncondensing
  • Non-operating: 5% to 80%, noncondensing
