At their core, mainframes are high-performance computers with large amounts of memory and processors that process billions of simple calculations and transactions in real time. The mainframe is critical to commercial databases, transaction servers, and applications that require high resiliency, security, and agility.
IBM® mainframes are uniquely engineered to:
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 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.
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.
