Features that Make Modern Mainframe Computers Stand Out

Numerous computing technologies have emerged since the invention of mainframe computers. But the demand for mainframes continues because of their RAS (Reliability, Availability and Serviceability). They are used extensively to perform critical operations in the world's largest corporations and in governments across the globe.

Let us discuss the unique features offered by mainframe computers, which make them the most reliable computing solutions.

High processing capacity
The processing capacity of mainframe computers is unparalleled by any other computer. Mainframes are designed to handle large numbers of high-power embedded processors that can effectively handle huge volumes of input and output (I/O). The main processor of a mainframe computer is, thus, left free from I/O operations and is completely delegated to application processing. This feature provides mainframe computers with great processing capacity, which enables them to deal with massive databases effectively.

Huge memory storage
Because mainframe computers are designed for large-scale operations, they also possess vast memory capacity to support those operations. A typical mainframe has more than 8 gigabytes of memory embedded.

Can run multiple operating systems
Every mainframe computer can run multiple operating systems. Mainframes have a special feature that enables them to work as multiple virtual machines for each operating system. Thus a single mainframe computer not only hosts multiple operating systems, but also replaces hundreds of small servers, thus eliminating the need for other hardware. Some of the operating systems supported by mainframes are UNIX, Linux, z/OS, z/VM, z/VSE, and z/TPF.

Centralized computing
Mainframe systems offer centralized computing, which enables a user at a single desktop monitor to check all the operations that take place in the mainframe processor. This feature of mainframes effectively reduces management and administrative costs.

Application debugging
With multiple levels of analysis, mainframe computers enable detailed tracing and logging. An application programmer can test the functionality of modules, monitor running jobs, and then check the output to verify the results. That kind of thorough application debugging helps to design time and run-time problem diagnosis with more number of capture points.

Real-time monitoring and control
Mainframe computers effectively handle performance management of a network. They measure, analyze, and report the status and performance of IT resources in real time. They provide immediate alerts and real-time reports that enable quick problem identification and resolution.

Supports large number of users and application programs
Mainframes are designed to allow huge number of users and applications to simultaneously access numerous resources without interfering with each other. At the same time, they also ensure security standards are maintained properly.

Since 1982, Software Diversified Services is providing first-quality software and technical support for IBM mainframes and VM, VSE, ftp to mainframe and z/OS systems. SDS mainframe software provides security, encryption, compression for mainframe data, OSA express monitoring, secure file transfer (SFTP), SNA and IP network management and automation.
