Why IBM mainframe servers?

IBM Z® mainframes deliver millisecond response time, extreme reliability, near 100% uptime and the world’s best security.

The newest mainframe, IBM® z14™ (z14), is designed for trusted digital experiences. This enterprise system delivers pervasive encryption, stronger clouds, real time insights, machine learning and transparent blockchain.

Compare mainframes

IBM z14

The newest generation mainframe enables the ultimate protection for your data, simplifies compliance, harnesses machine learning and is the better cloud data center platform.

IBM z13s

The capabilities of the z13 in a smaller footprint and affordable price. It’s a lower entry point for a highly available and secure system for hybrid cloud and real-time analytics.

IBM z13

This earlier generation speeds insight, protects transactions to minimize exposure and risk and offers scale. It was the best mainframe available until the z14.

I/O connectivity

IBM mainframes can have up to 1024 individual channels for input and output (I/O) connectivity with plenty of room for scalability and “always on” capability.


IBM Z servers provide an advanced combination of reliability, availability, security, scalability and virtualization, together with the ability to re-allocate processing via power matching to adapt and change business networking priorities on demand.


With, IBM Z mainframe servers, planned outages are a thing of the past, allowing applications to stay up 24 x 7, all while making concurrent changes to the environment if needed.


IBM mainframe servers offer enterprise security across cloud, blockchain and analytics. IBM Z anticipate vulnerabilities and provide multiple levels of security from infrastructure to endpoint.


GDPS, or “Geographically Dispersed Parallel Sysplex, can manage high availability and potential disaster recovery needs from any virtual location.


The Large System Performance Reference or (LSPR) ratios are IBM's assessment of relative processor capacity in an unconstrained environment for specific benchmark workloads and system control programs.

Parallel Sysplex

Multi-system data sharing technology allows direct and concurrent read/write access to shared data from all processing nodes in the configuration without sacrificing performance or data integrity.
