Two Mainframe Models

Two mainframe models:-                 Mainframes are available with a variety of processing capabilities to suit the requirements of most business organizations. In the case of IBM, for example, each mainframe model provides for sub-capacity processors from granular processing requirements up to the full range of high-end computing. Let’s look at two entries from IBM (Figure 1-3): System z Business Class (BC) System z Enterprise Class (EC) Fig:-System z  Business and Enterprise class                        The System z Business...

Old and New Mainframe

Old and New Mainframe:-                     A highly secured computer system designed to continuously run large, mixed workloads at high levels of utilization while meeting user-defined service level objectives.                     Early mainframe systems were housed in enormous, room-sized metal boxes or frames, which is probably how the term mainframe originated. The early mainframe required large amounts of electrical power and air-conditioning, and the room was filled mainly with I/O devices. Starting around 1990, mainframe processors and...

Introduction Of Mainframe

Mainframe computers ("big iron") are computers used primarily by large organizations for critical applications, bulk data processing such as census, industry and consumer statistics, enterprise resource planning, and transaction processing. It is the high performance computer supporting multiple user at the same time. It provides the high security and processes the millions of data. Mainframe can use for:- Reliability:- System can recover from failure  Availability : - Recover data or component without affecting other programs.  Serviceability:- System itself find what has been wrong and give message  Scalability:-Upgrading...
