Tivoli Storage Manager for Windows Administrator's Guide


Planning for Devices

Administrators should make several operational decisions when adding devices.

  1. Determine the device driver that supports the device.
  2. Determine whether client data is backed up directly to tape or to a storage hierarchy.
  3. Determine which client data is backed up to which device in environments using mixed device types.
  4. Determine if media will be managed by an external media manager like Removable Storage Manager (RSM) or Tivoli Removable Storage Manager (TRMM).

For each device defined to TSM, the Device Configuration Wizard creates a storage pool, a collection of media for the device. Administrators determine the backup device for a client's data when that client is associated with a storage pool.

Tape drive performance often depends on the way that devices are positioned in the storage hierarchy and whether the server is a stand-alone implementation or a networked implementation. A TSM server in a stand-alone implementation can go directly to tape to reduce contention for disk resources. Networked TSM servers benefit from a storage hierarchy where files are backed up to disk and migrated to tape later. See Chapter 11, "Implementing Policies for Client Data" and "Overview: The Storage Pool Hierarchy".
