| | DAB (BS2000/OSD) |
Manages peripheral data caching to enhance I/O and applications performance |
Current version: V9.1
Announced version: V9.2
Sophisticated, scalable and self-adaptive caching technologies are fundamental for performant, self-optimising E-Business-applications with guaranteed response-times (Business Critical Computing). Caches accelerate the reading and writing of data by factors. They are applied in networks, servers and disk subsystems. DAB is the BS2000/OSD-software for disk data caching in main memories or/and in Global Storages of BS2000-Servers.
The Disk Access Buffer (DAB)- manages the caching of peripheral data on high-speed semiconductor memories
- buffers the data in intermediate storage (caching) with far shorter access times than those possible for external data storage (disk storage)
- can use various types of storage media (such as main memory (MM) and global storage (GS)) as buffers
- supports main memories up to 2 Tbytes and files up to 4 Tbytes.
- supports data spaces and file encryption.
The advantages of DAB are apparent in both sequential processing and in very localized random-access processing. DAB also provides write caching for significant performance gains in applications with high write rates.
