IBM mainframes are uniquely engineered to:

• Run common operating systems like Linux®, specialized operating systems such as IBM z/OS®, and software that takes advantage of unique hardware capabilities.
• Support massive simultaneous transactions and throughput (I/O) with built-in capacity on demand and built-in shared memory for direct application communication.
• Deliver the highest levels of security with built-in cryptographic cards and innovative software. For instance, the latest IBM zSystems® mainframes can execute up to 1 trillion secure web transactions per day and manage privacy by policy.
• Offer resiliency through multiple layers of redundancy for every component (power supplies, cooling, backup batteries, CPUs, I/O components, cryptography modules) and testing for extreme weather conditions.

Today’s mainframes are much smaller than the early “Big Iron” machines. With a standard 19” rack, the latest mainframe seamlessly coexists with other platforms in the data center. One IBM zSystems single-frame system requires 75 percent less floor space than x86 2U servers running the same workloads and throughput – and reduces power consumption by 40 percent.

The core design values of the mainframe have always been reliability, scalability, compatibility and security.

Today’s mainframe is designed with next-level data privacy, enterprise security and cyber resiliency – all delivered through a hybrid cloud.
