Real-time Compression solutions
Disk systems: IBM Real-time Compression Appliances, STN6500 and STN6800, fit between NAS systems and network switches, and can compress files and databases up to 80%. IBM Real-time Compression Appliances can increase application throughput and user response time by helping to improve the efficiency of both application servers and the storage systems.
Database software: IBM’s premier database products, DB2 (US) and Informix (US), both support optional compression functions that can compress database data up to 80%. Compression processing is performed on the database server, but the reduction in I/O processing can more than make up for the compression overhead.
Other IBM Data Compression solutions:
Data compression is a core storage efficiency technology in most data centers. IBM data compression utilities and product features are commonly used to reduce the cost of storing inactive files, backups, archives.
Tape: IBM includes compression on a chip, for both enterprise and LTO tape drives, so compression happens with little or no impact on throughput.
Virtual Tape: IBM ProtecTIER Data Deduplication (US) products perform compression after the deduplication process for additional efficiency, a feature that is easily adjusted for use with primary data compression products.
Backup software: IBM Tivoli Storage Manager (US) enables client level and drive level compression for disk-based and tape-based backup.
File Systems: IBM Power Systems running AIX® Journaled File System (JFS) optionally support compressed file systems. File system compression has some user response time impact, but can be ideal for infrequently accessed smaller files.
Compression utilities: Data centers rely on compression utilities to reduce the size of inactive archives. PKZIP, PKARC, compress, FTP, HTTP, and other important tools use compression.
