Subnet Management

Subnet Management Agents

A Subnet Management Agent processes management requests from the Subnet Manager. Subnet Management Agents are implemented on all nodes within the InfiniBand fabric. These nodes include IB-capable switches, routers, and channel adapters. Each node implements a Subnet Management Agent. Within the SFS 7024 Switch, a Subnet Management Agent (SMA) is implemented within its firmware. An SMA also runs on every InfiniBand-capable server that is equipped with an HCA. As shown in Figure 1-3the Subnet Manager interacts with these SMAs to discover information about the nodes on the fabric.

The Subnet Manager utilizes the agent information to discover and manage connections from the SFS 7024 to the InfiniBand fabric. The Subnet Manager maintains a database tracking subnet topology information as a result of its interaction with the SMAs.

InfiniBand General Services Managers and Agents

The InfiniBand specification defines the InfiniBand General Services Managers and their associated agents. General Services Managers exchange messages with agents to manage and monitor the performance and the physical environment of devices on the network.

Once the InfiniBand network is up and running, the InfiniBand General Services Managers begin to interface with General Services Agents. The General Services Managers and Agents include:

Subnet Administration (SA)

SA provides InfiniBand fabric nodes with an interface to the Subnet Manager. This interface is used by the nodes on the fabric to interact with the Master Subnet Manager and to discover information about the fabric. Every InfiniBand fabric subnet requires a SA.

The Device Manager (DM) and Device Management Agent (DMA)

The DM and DMA discover and manage the association between hosts and devices behind the Target Channel Adapters.
