Brocade 6542 Blade Server SAN I/O Module for Inspur Shangri-la Chassis Hardware Reference Manual

Port negotiation
Sixteen external 16-Gbps FC ports support 4-, 8- and 16-Gbps transmit and receive rates with
autonegotiation. You can also install 8- and 16-Gbps SFP+ optical transceivers, which allow respective
transmit and receive rates with autonegotiation. The actual data signaling rate used on a port is
automatically sensed and set to the rate supported by the device or devices attached to the port.
If the switch module is connected to a device, but unable to negotiate the signaling rate, you can
manually set the speed of each port through the management interface. The switch module is
compliant with current Fibre Channel standards, including most current-generation switch N_Ports,
F_Ports, and E_Ports, as well as host adapters, Redundant Array of Independent Disks (RAID)
storage devices, hubs, Fibre-SCSI bridge devices, and older switch families.
Operating system support
Brocade Fabric OS has no specific host operating system dependencies. The Fabric OS in the
switches allows for any Fibre Channel-compliant device to attach to switches as long as it conforms to
the standards for device login, name service, and related Fibre Channel features.
For more information regarding supported operating systems, refer to the documentation that comes
with your Inspur Shangri-la Blade Server.
Accessing the switch module
The switch module is managed as a single element. It has a single IP address and appears as a
separate entity to the Telnet protocol and the Simple Network Management Protocol (SNMP).
When SNMP devices send SNMP messages to a management console running SAN management
software, the information is stored in a Management Information Base (MIB). The switch module with
Fabric OS 7.4.0_ins and later supports the FibreAlliance Fibre Channel Management (FCMGMT)
MIBs, allowing the provision of needed information to a SAN administrator.
In addition, the Brocade Fabric Access Layer (API) and the Storage Management Initiative (SMI)
provide facilities for the discovery and management of physical and logical elements in a SAN. Using
the Fabric Access interface to the Fabric OS, a client application can retrieve information and modify
the configuration of Brocade switches in the fabric.
Secure Telnet access is available using Secure Shell (SSH), a network security protocol for secure
remote login and other secure network services over an insecure network.
Brocade Web Tools management is available through a secure browser using Secure Sockets Layer
(SSL). The SSL security protocol provides data encryption, server authentication, message integrity,
and optional client authentication for a TCP/IP connection. Because SSL is built into all major
browsers and web servers, installing a digital certificate enables the SSL capabilities.
Access Gateway mode default port mapping
The switch module contains 48 total ports. Of these, ports 1 through 32 are internal F_Ports. Port 0
and ports 33 through 47 are external ports that can be in F_Port, N_Port, or E_Port mode. The
following table describes the factory-default F_Port to N_Port mapping for the Access Gateway mode.
