If the partitioned index is aligned, the memory requirement is reduced to four processors sorting 40 pages, or 160 (4 * 40) pages. Partitioning allows a table, index, or index-organized table to be subdivided into smaller pieces, where each piece of such a database object is called a partition. These indexes do not apply to nonpartitioned table. For example, if the database engine sets DOP to 4, a nonaligned partitioned index with 100 partitions requires sufficient memory for four processors to sort 4,000 pages at the same time, or 16,000 pages.
