Auxiliary Storage Pool

Auxiliary Storage Pool

In IBM's i5/OS operating system, disk drives may be grouped into Auxiliary Storage Pools, generally referred to as "ASP"s, in order to organize data to limit the impact of storage-device failures and to reduce recovery time. [cite web |title=i5/OS Glossary |work=IBM Systems Information Center |publisher=IBM |url=http://publib.boulder.ibm.com/infocenter/systems/scope/i5os/topic/rzaat/rzaata.htm |accessdate=2008-07-11] If a disk failure occurs, only the data in the pool containing the failed unit needs to be recovered. "ASP"s may also be used to improve performance by isolating objects with similar performance characteristics, for example journal receivers, in their own pool.

By default, all disk drives are assigned to pool 1. Additional pools can be created, but this is rarely done anymore. The concept of i5/OS pools is similar to the Unix/Linux concept of volumes; however, with i5/OS it is typical for all disk drives to be assigned to a single ASP.
