1 Management server Management server - The management server provides a single point for managing the fabric. This is the only service that users can configure. See "Management server" below for more details Alias server - The alias server keeps a group of nodes registered as one name to handle multicast groups. Broadcast server - The broadcast server is optional. When frames are transmitted to this address, they are broadcast to all operational N_ and NL_Ports. When registration and query frames are sent to a well-known address, a different protocol service, Fibre Channel Common Transport (FC-CT), is used. This protocol provides a simple, consistent format and behavior when a service provider is accessed for registration and query purposes. Management server The Brocade Fabric OS management server (MS) allows a SAN management application to retrieve information and administer interconnected switches, servers, and storage devices. The management server assists in the autodiscovery of switch-based fabrics and their associated topologies. A client of the management server can find basic information about the switches in the fabric and use this information to construct topology relationships. The management server also allows you to obtain certain switch attributes and, in some cases, modify them. For example, logical names identifying switches can be registered with the management server. The management server provides several advantages for managing a Fibre Channel fabric: • It is accessed by an external Fibre Channel node at the well-known address FFFFFAh, so an application can access information about the entire fabric management with minimal knowledge of the existing configuration. • It is replicated on every Brocade switch within a fabric. • It provides an unzoned view of the overall fabric configuration. This fabric topology view exposes the internal configuration of a fabric for management purposes; it contains interconnect information about switches and devices connected to the fabric. Under normal circumstances, a device (typically an FCP initiator) queries the name server for storage devices within its member zones. Because this limited view is not always sufficient, the management server provides the application with a list of the entire name server database. Platform services By default, all management services except platform services are enabled; the MS platform service and topology discovery are disabled. You can activate and deactivate the platform services throughout the fabric. Activating the platform services attempts to activate the MS platform service for each switch in the fabric. The change takes effect immediately and is committed to the configuration database of each affected switch. MS activation is persistent across power cycles and reboots. NOTE The commands msplMgmtActivate and msplMgmtDeactivate are allowed only in AD0 and AD255. 44 Fabric OS Administrator's Guide 53-1002745-02
