McDATA Products in a SAN Environment - Planning Manual
5-10
The management server provides an auto-detecting 10/100 Base-T
Ethernet interface that connects to the 24-port hub mounted at the top
of the Fabricenter equipment cabinet. Each director CTP card, fabric
switch front panel, or SAN router front panel also provides an
auto-detecting 10/100 Base-T Ethernet interface that connects to the
hub. Factory-installed cables connect the management server, hub,
and managed products.
Although directors provide two Ethernet connections to the hub, only
one connection is active at a time. The interface on the backup CTP
card remains passive until a failure on the active CTP card occurs, at
which point the redundant CTP card becomes active using the same
media access control (MAC) address as the original interface.
If an optional customer intranet is used for LAN connections, the
management server provides a second auto-detecting 10/100 Base-T
Ethernet connection. This interface is used for remote workstation
access.
The management server has an internal modem for service and
support of managed products. The modem provides a dial-in
capability that allows authorized service personnel to communicate
with the management server and operate the SAN management and
Element Manager applications remotely.
The modem is also used to automatically dial out to an authorized
support center (to report the occurrence of significant system events)
using a call-home feature. The call-home feature is enabled in the
Element Manager application and configured through the dial-up
networking feature of Windows 2000.
Directors, fabric switches, SAN routers, and the management server
are delivered in a cabinet-mount configuration in accordance with
customer specifications. Because Ethernet cables that connect the
managed products, hub, and management server are factory-
installed, connectivity planning is not required for a stand-alone
cabinet installation. However, consider the following Ethernet
connectivity issues when:
•
Installing additional cabinet-mount products - When installing
an additional fabric element, the length of Ethernet cable required
to provide hub connectivity is a function of cabinet position (top,
bottom, or adjacent to the management server). Ensure cable
lengths provide sufficient cable inside the cabinet to route to
product Ethernet ports and to allow service clearance.
