Enterprise-class mainframe systems — high-performance, highly reliable servers for mission-critical transaction and data workloads.
This subcategory covers complete mainframe systems: large-scale enterprise-class servers engineered for continuous operation, maximum reliability and security, and processing of very high transaction volumes. Modern mainframes integrate AI acceleration (on-chip and PCIe cards), advanced cryptography and virtualization, running operating systems such as z/OS and Linux. They are used in banking, insurance, government and other sectors with stringent SLA requirements.

IBM's family of Linux-optimized mainframe servers, built on the IBM Telum II processor. The latest LinuxONE 5 (Emperor 5) generation adds AI acceleration and quantum-safe encryption.

Enterprise-class IBM mainframe (machine type 9175) with the 5.5 GHz IBM Telum II processor, up to 208 cores and 64 TB memory, engineered for in-transaction AI inference.
