In IBM's i5/OS operating system, disk drives may be grouped into an auxiliary storage pool (ASP) in order to organize data to limit the impact of storage-device failures and to reduce recovery time. If a disk failure occurs, only the data in the pool containing the failed unit needs to be recovered. ASPs 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.
Famous quotes containing the words storage and/or pool:
“Many of our houses, both public and private, with their almost innumerable apartments, their huge halls and their cellars for the storage of wines and other munitions of peace, appear to me extravagantly large for their inhabitants. They are so vast and magnificent that the latter seem to be only vermin which infest them.”
—Henry David Thoreau (1817–1862)
“I’ th’ world’s volume
Our Britain seems as of it, but not in’ t;
In a great pool a swan’s nest.”
—William Shakespeare (1564–1616)
