Physical Planning Considerations
Connectivity Planning
Considerations
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.
Interconnecting Fabricenter cabinets - To increase the products
managed by one management server, Ethernet hubs in one or
more equipment cabinets must be connected. Plan for an Ethernet
cable length that meets the distance requirement between
cabinets. In addition, plan for an additional 1.5 meters (5 feet) of
cable outside the cabinet to provide slack for service clearance,
limited cabinet movement, or inadvertent cable pulls. Store extra
Ethernet cable in the cabinet or under the computer room raised
floor.
Consolidating management server operation - For control and
efficiency, all directors, fabric switches, and SAN routers in a
multiswitch fabric or routed SAN should be managed by one
management server. When products in two or more cabinets are
joined to form a fabric, the PC environment should be
consolidated to one server and one or more clients. Plan for
Ethernet cabling to interconnect cabinets and ensure all fabric
elements and PC platforms participating in the fabric have
unique IP addresses.
Remote User
Workstations
Customer system administrators determine whether to allow access
to directors and switches from remote workstations. If administrators
allow remote sessions, they may restrict access to selected
workstations by configuring the IP addresses of those workstations
through the SAN management application. When a remote session is
allowed, the remote user has the same rights and permissions as if the
session were on the local management server. Up to 25 sessions can
be simultaneously active.
