Improving operational efficiency

The z13s offers many capabilities designed to improve efficiency in the data center. Specialty engines such as the Integrated Facility for Linux (IFL), IBM System z® Integrated Information Processor (zIIP), Internal Coupling Facility (ICF) or additional System Assist Processors (SAPs) are designed to help optimize the capabilities of the platform to support a broad set of applications and workloads, while helping to dramatically improve mainframe economics.

Advancing quality of service

The z13s enables enterprise-grade Linux, one designed to be more robust and trusted for critical workloads, has higher performance and throughput at a lower cost per transaction and is integrated with new open capabilities that will lead to wider adoption of open source content. You need IBM Z systems qualities of service for your Linux applications and the z13s, along with open source investments, delivers enhancements to availability, scale, and security to meet these demands.

Delivering your real-time vision

Built on IBM Z mainframe core values and strengths, the z13s delivers innovations and technologies to enable real-time digital business. It is designed to handle the explosive growth of increasingly mobile clients and employees, able to leverage new and vast amounts of data, and can provide deeper real-time insight at the point for greatest business impact. All this can be deployed within a secure and resilient cloud-ready infrastructure.
