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.
