Chapter 2 — Architecture Overview
Storage pool The chambers in a storage partition's storage pool provide
the cartridge storage for a partition. You specify the number of chambers
assigned to the storage pool when you create a partition. See the next
section, Library Partitions, for detailed information about how the storage
pool is used in partitions.
 Each storage partition has its own storage pool; the pool contains at

Partitions divide the library logically so that it appears as one or more
physical libraries — o ne library per configured partition. Partitioning
simplifies storage consolidation through the creation of virtual libraries,
each with its own drives and media. Each partition:
 Has exclusive access to the tape drives and media storage assigned to it.
 Can control the robotics to move media within the partition.
The library supports two types of partitions, storage partitions and
cleaning partitions. You can configure a maximum of 16 partitions using a
maximum of six physical controllers. One or more cleaning partitions can
be configured in a single library. A single cleaning partition can be
associated with multiple storage partitions. Cleaning partitions do not
count against the partition maximum.

least one chamber. The cartridges in the storage pool are available for
use by the host storage management software that accesses the
partition.
be shared by multiple storage partitions if they all use the same type of
cleaning cartridge. The cleaning cartridges stored in the cleaning
partition are only accessible when the library is configured to use the
Auto Drive Clean feature. They are not accessible to the storage
management software.
 A single RIM2 can export up to 16 partitions.
Notes:
 An LTO drive can only export one partition.
 The more partitions in a library, the longer each move can
take. If move requests can be sent to several partitions at
once, you may need to increase the timeout setting in your
storage management software.
