Product Management
47SAN High Availability Planning Guide
Product Firmware
Director or edge switch firmware provides services that manage and maintain
Fibre Channel connections between ports. Although the product hardware
transmits Fibre Channel frames between source and destination ports, the
firmware maintains routing tables required by the hardware to perform these
switching functions. Product firmware also provides functions for system
configuration, control, maintenance, and redundancy management, including:
■ System Management Services — This function configures, controls, and
monitors director and switch operation. The subsystem:
— Centrally manages all configuration and status information.
— Manages network connections from the HAFM appliance.
— Implements a simple network management protocol (SNMP) agent to
allow access by external SNMP managers using the Fibre Channel Fabric
Element management information base (MIB), standard Transmission
Control Protocol/Internet Protocol (TCP/IP) MIB-II definition, or
product-specific MIB.
■ Fabric Services — This function supports the fabric controller (login server)
and name server. For the director, fabric services also implements a
replication manager that synchronizes node port (N_Port) registration
databases between redundant control processor (CTP) cards and allows
transparent CTP failover.
■ Fibre Port Services — This function provides a physical driver for hardware
components, including:
— Director 2/64 universal port module (UPM) cards and serial crossbar
(SBAR) assemblies.
— Edge Switch 2/16 and Edge Switch 2/32 fiber-optic ports.
■ Fibre Channel Protocol Services — This function provides the Fibre
Channel transport logic that allows upper layer protocols used by fabric
services to communicate with devices attached to fiber-optic ports.
■ Network Services — This function provides TCP/IP transport layers to
access management service subsystems from attached management clients.
These clients include the HAFM appliance or an SNMP management station.
■ Application Services — This function supports all software subsystems for
system initialization, logging, tracing, debugging, and communicating with
the RS-232 maintenance port.
