Run common operating systems like Linux, as well as specialized operating a systems such as z/OS and software to take advantage of the unique hardware capabilities.
Support more simultaneous transactions and higher levels of throughput (I/O) compared to other computers through built-in capacity on demand and a built-in Internal Shared Memory solution.
Deliver the highest levels of security by building cryptographic cards into the hardware.
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 z15 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.
