The first version of OCFS was developed with the main focus to accommodate Oracle's database management system that used cluster computing .
This strategy enables the sequential access to a relation to be done in parallel. However, the direct access to individual tuples, based on a predicate, requires accessing the entire relation. Hash partitioning: applies a hash function to some attribute that yields the partition number. This strategy allows exact-match queries on the selection ...
After Oracle acquired Sun, Oracle continued to develop the SAM-QFS product. Later Oracle renamed SAM-QFS to Oracle HSM (Oracle Hierarchical Storage Manager). [ 7 ] In 2014 Versity , a storage startup co-founded by SAM-QFS lead architect Coverston, released the Versity Storage Manager (VSM), a Linux-based HSM based on the SAM-QFS code. [ 3 ]

Before version 4.0, OS/2 shipped with two partition table managers. These were the text mode fdisk [15] and the graphical fdiskpm. [16] The two have identical functionality, and can manipulate both FAT partitions and the more advanced HPFS partitions. OS/2 4.5 and higher (including eComStation and ArcaOS) can use the JFS file system, as well as ...
