With Tivoli® Storage
Manager,
you can use direct-attached storage devices and network-attached devices
for server storage.
Tivoli Storage
Manager represents
physical storage devices and media with the following administrator-defined
objects:
- Library
- A library is one or more drives (and possibly robotic devices)
with similar media-mounting requirements.
- Drive
- Each drive represents a drive mechanism in a tape device.
- Data mover
- A data mover represents a device that accepts requests from Tivoli Storage
Manager to transfer
data on behalf of the server. Data movers transfer data between storage
devices.
- Path
- A path represents how a source accesses a destination. For example,
the source can be a server, and the destination can be a tape drive.
A path defines the one-to-one relationship between a source and a
destination. Data can flow from the source to the destination, and
back.
- Device class
- Each device is associated with a device class that specifies the
device type and how the device manages its media.
- Storage pools and volumes
- A storage pool is a named collection of volumes that have the
same media type. A storage pool is associated with a device class.
A storage pool volume is associated with a specific storage pool.
For
example, an LTO tape storage
pool contains only LTO tape volumes.
