I write about z/OS, Capacity Planning and all things Mainframe

Parallel Sysplex is a cutting-edge technology designed to provide unparalleled reliability, redundancy, and robustness in mainframe systems, ensuring near-continuous availability.

To assist in planning for zIIP, components of z/OS have been enhanced to report both projected zIIP usage and actual zIIP usage.

PR/SM enables the z13 to be initialized for a logically partitioned operation, supporting up to 85 LPARs.

IBM mainframes have been providing high quality, high availability service for decades. They are still being used today, but there are some new benefits that are being explored.

The OSA-Express4S 10 Gigabit Ethernet (10 GbE) feature on zEC12, z196, and z114 servers has been enhanced to provide improved performance for inbound traffic.

The HiperSockets function, also known as internal queued direct input/output (internal QDIO or iQDIO), is an integrated function of the zEC12, z196, and z114 that provides users with attachments to up to 32 high-speed virtual LANs and is designed to minimize system and network overhead.

Linux on System Z is a cost-attractive IT optimization solution model that can help you reduce costs and improve efficiency.
