Physical Planning Considerations 5 Management Server Connectivity Connectivity Planning Considerations 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 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. 5-10 McDATA Products in a SAN Environment - Planning Manual
