Product Management 2 Firmware Services • E/OSi - The Enterprise Operating System (internetworking) performs system configuration, management, and Fibre Channel and IP-based routing functions for Eclipse-series SAN routers. Director and fabric switch firmware (E/OS and E/OSn) provides services that manage and maintain Fibre Channel connections between ports. Although product hardware transmits Fibre Channel frames between source and destination ports, the firmware maintains routing tables required by hardware to perform switching functions. SAN router firmware (E/OSi) provides services that manage and maintain both Fibre Channel and IP-based port connectivity. Product firmware also provides: • System management services - This function configures, controls, and monitors product operation. • Application services - This function supports all software subsystems for system initialization, logging, tracing, debugging, and communicating with RS-232 maintenance ports. • Operating system services - This function includes boot and loader software, a command line monitor for engineering fault isolation, a serial maintenance port driver, and other support for the product operating system. • Network services - This function provides both transmission control protocol/Internet protocol (TCP/IP) and user datagram protocol/Internet protocol (UDP/IP) transport layers to access management service subsystems from attached management clients. These clients may include (depending on the product) the out-of-band management server, SANpilot interface, CLI, or SNMP management workstation. • 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. • Fibre port services - This function provides a physical driver for hardware components. 2-12 McDATA Products in a SAN Environment - Planning Manual
