Physical Planning Considerations 5 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 factoryinstalled, 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.
