IBM 2109 Model M12, User Manual

Page: 35 / 97

The Fabric OS for the 2109 Model M12 allows any Fibre Channel-compliant device
to attach to the switches as long as it conforms to the device login, name service,
and related Fibre Channel feature standards. Each operating environment requires
that a Fibre Channel host bus adapter (HBA) be available with a
standards-compliant driver for proper interface to the fabric.
Fabric OS consists of a set of embedded applications that run on top of an
embedded real-time Linux operating system kernel. These applications include the
following:
v
Name server
v
Alias server
v
Simple Network Management Protocol (SNMP) agent
v
Several tasks to manage the following:
– Address assignment
– Routing
– Link initialization
– Fabric initialization
– Link shutdown
– Switch shutdown
– User interface
Interoperability
Fabric OS Version 4.1 interoperates with 3534 Model 1RU (minimum version 2.6).
McData ED-5000 (from operating system version 4.0) interoperability is also
provided.
Security
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.
Web Tools management is available through a secure browser by 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 turns on the SSL capabilities. For more information about Web
Tools, see the Brocade Advanced Web Tools User’s Guide.
Network manageability
The entire switch is managed as a single element and appears as a single element
to a Network Management System (NMS). Each 64-port switch responds to its own
IP address and appears as a separate entity to the Telnet protocol and the SNMP.
The management interfaces include blade assemblies as an intermediate
component between switches and ports. In addition, all management interfaces
such as, Telnet, Web Tools, the Fabric Access Layer API, and Management Server,
support a “port N within blade M” naming scheme.
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 Fabric OS Version of the 2109 Model M12 supports the latest
