Data Compression

When choosing a management solution for the physical infrastructure of IT networks,management of individual devices is necessary in order to have visibility to the many datapoints required for the reliable operation of network-critical physical infrastructure.Element management solutions offer the optimum approach as they manage a particulartype of device and have the ability to assimilate and, more importantly, make manageablethe large volume of data necessary for network availability.<!-- management solutions, IT networks, devices, network-critical physical infrastructure, data, network availability, cost of deployment, cost maintenance, adaptability, business needs change, functionality, ease of integration --> tech news

This paper is an overview of the use of hardware data compression with IMS databases. It explains how you define compression exit routines and how IMS implements their use. IMS implements compression through Segment Edit/Compression Exit routines. These routines reduce the amount of space used by segments in VSAM CIs and OSAM blocks. This reduces the size requirements for the database data sets. The use of compression does not affect application programs. tech news

Wide-area client-server applications are a critical part of almost every large enterprise. However, access to widely used and critical infrastructure across WANs (like file servers,mail servers and networked storage), is handicapped by very poor response time when compared to the performance across Local Area Networks (LAN). This white paper will explore the concerns surrounding WAN performance, and will detail a new approach that can help improve overall performance. tech news

This White paper describes the results of testing the data compression algorithms of Super Tape Drives. The testing requirements were to compare the data compression algorithm performance of the SDLT 320 manufactured by Quantum against the Linear Tape Open (L.T.O.) drives from HP, IBM, and Seagate and the Advanced Intelligent Tape drive from Sony. tech news
