Chapter 1. Storage Agent Overview

IBM Tivoli Storage Manager for Storage Area Networks is a feature of Tivoli

Storage Manager that enables LAN-free client data movement.

This feature allows the client system to directly write data to, or read data from, storage devices attached to a storage area network (SAN), instead of passing or receiving the information over the network. Data movement is thereby off-loaded from the LAN and from the Tivoli Storage Manager server, making network bandwidth available for other uses. For instance, using the SAN for client data movement decreases the load on the Tivoli Storage Manager server and allows it to support a greater number of concurrent client connections. See Figure 1 on page 2. The storage agent, a component of the feature, makes LAN-free data movement possible.

The storage agent can support several clients while installed on only one of the clients. You can install the storage agent on a client machine that shares storage resources with the Tivoli Storage Manager server (Figure 1 on page 2) or on a client machine that does not share storage resources but is connected to a client machine that does share storage resources with the Tivoli Storage Manager server. Figure 2 on page 2shows multiple clients connected to a client machine that contains the storage agent. You must specify the LANFREECOMMMETHOD option in the client system options file (dsm.sys) to allow the client machine (that shares storage resources) to communicate with the storage agent. A Tivoli Storage Manager server, acting as a library manager, controls the storage devices. This server may be the server working in conjunction with the storage agent or another Tivoli Storage Manager server in the enterprise. The Tivoli Storage Manager server keeps track of the metadata that the client has stored. The metadata, such as policy information and file name and size, is passed over the LAN connection between the storage agent and server.
