Task 17: Plan SAN Routing (Optional)

If a routed SAN is to be implemented, carefully plan metropolitan
area network (MAN) or wide area network (WAN) connectivity and
the integration of SAN routers with standard fibre channel fabric
elements.
Ensure basic requirements for physical SAN routers are incorporated
in the site plan(s) developed while performing
Plan. Plan equipment cabinet locations; availability and location of
Ethernet LAN connections and cabling; and power requirements. The
following router-specific factors should also be considered:
• Management server support - At each location that requires
server support for one or more SAN routers, consider the
following:
— The 10/100 Base-T Ethernet management port on each SAN
router provides out-of-band connectivity to the management
server. Gigabit Ethernet (GbE) intelligent ports on each SAN
router provide inband IP network connectivity to transmit
storage traffic. The management port and intelligent ports
require network address configuration, including an IP
address and subnet mask. It is recommended the management
port be configured on a separate subnet from intelligent ports.
— The SANvergence Manager application (management server
resident) and Element Manager application (router resident)
use SNMP and hypertext transfer protocol (HTTP) to
communicate. To ensure communication, Java runtime
environment j2re-1_4_2_01-windows-i586-iftw.exe (or later)
must be installed on the management server. The software is
downloaded from http://java.sun.com.
— The management server port communicating with a SAN
router must be set to Auto Negotiate to ensure viable
server-to-router communication.
• Fibre Channel network connections - At each location,
fiber-optic cables with appropriate connectors must be routed
between Fibre Channel elements (storage devices, servers,
directors, and fabric switches) and the SAN router. Eclipse-series
SAN routers support small form factor pluggable (SFP) optical
transceivers with LC duplex connectors.
