Subnet Manager

Every InfiniBand fabric subnet requires a single active Subnet Manager (SM) to initialize and maintain the subnet. The fabric may also have one or more standby Subnet Managers. One of the standby Subnet Managers can be configured to become the active SM in the event of a failure.

As Figure 1-2shows, InfiniBand-enabled fabrics consist of one or more subnets. Each subnet consists of a number of InfiniBand-capable servers connected to target devices. InfiniBand-capable routers provide connectivity between InfiniBand subnets.

When a network is initially powered up, the Subnet Manager queries the subnet management agents running on the network devices, for information about node/port addressing schemes, routing tables and partitions. From that point on, the Subnet Manager periodically sweeps the network for changes. Once the InfiniBand network is up and running, the InfiniBand General Services Managers (GSMs) begin to interface with General Services Agents (GSAs).
