What is workload management?

Your workloads have different, often competing, completion and resource requirements. These requirements must be balanced in order to make the best use of the resources of an installation, maintain the highest possible throughput and achieve the best possible system responsiveness.


Why run mission critical workloads on IBM Z?

The IBM Z® platform can run multiple workloads at the same time within one z/OS® image or across multiple images; make the best use of the installation resources; maintain the highest possible throughput; and achieve the highest system resiliency and availability.

The new IBM z15™ requires 23 times fewer cores than comparable x86 servers and delivers a 27% lower overall TCO over 5 years when running mixed workloads consisting of both open source and IBM proprietary software.*


Workload management products

IBM Workload Manager for z/OS (WLM)

Define performance goals for workloads in business terms. WLM will monitor the system and adapt how much resource should be given.

IBM z/OS Management Facility (zOSMF)

Manage your z/OS systems through a browser at any time, from any location, and reduce the expertise needed to manage WLM.

IBM z/OS Resource Measurement Facility (RMF)

Collect performance data for z/OS and Sysplex environments and tune and configure your system with this optional feature.

z/OS Capacity Provisioning (CPM)

Address needs for short-term workload and processor utilization fluctuations for which On/Off Capacity on Demand or soft capping changes apply.

IBM Z Instant Recovery

Process your transactional backlog by up to 2x faster and process your batch backlog by up to 2.5x faster.

IBM HMC Mobile

Monitor your IBM Z mainframes and partitions from anywhere in the world.

*Disclaimer: The workloads consisted of an airline flight reservation system (running MongoDB and node.js) and a transactional core banking application (running WAS and Db2). Four instances of the airline system were run, one instance simulating a Dev/QA environment, and three instances simulating a Production environment. Seven instances of the core banking application were run, one instance simulating a Dev/QA environment and six instances simulating a Production environment. Dev/Test and Production environments were differentiated by their CPU utilization levels. Intel servers are generally run at an average of 10-30% utilization per IT Economics data.
