What is z/VM?

IBM® z/VM® is a highly secure and scalable hypervisor and virtualization technology for cloud infrastructure and for running critical applications. Learn about z/VM:

Virtualization benefits for IBM Z operating systems

IBM z/VM supports Linux, z/OS®z/VSE® and z/TPF operating systems on IBM Z® and LinuxONE™ servers. It can host thousands of virtual servers on a single system.

A continuous delivery model enables clients to exploit new z/VM capabilities at their own pace.

IBM z/VM is even better on the new z15

IBM tests indicate IBM z15 requires 23X fewer cores than compared x86 servers and a 20% lower overall 5-year TCO when running mixed workloads consisting of open source and IBM proprietary software.¹

Key virtualization features of z/VM software

z/VM Single System Image

This clustering technology helps reduce planned outages and balance workloads across z/VM systems.

z/VM Performance Toolkit

This toolkit provides enhanced capabilities to monitor and report performance data.

RACF Security Server

Robust security software for virtualization helps protect your z/VM and guest system resources.

DirMaint

IBM Directory Maintenance (DirMaint™) for z/VM helps manage z/VM’s user directory.

z/VM Spotlight

80 Logical Processor Support

z/VM has advanced the scaling capability again, increasing the limit of 64 logical processors to 80 logical processors. When combined with z/VM Single System Image (SSI) clusters, this can provide a 320 logical processor environment with the four SSI-members.

Hear from customers

Deploying new web-based applications for our customers is much easier with Linux on Z than with Windows on distributed servers. We can set up a new environment within minutes by firing up a virtual server on z/VM.

¹DISCLAIMER: This is an IBM internal study designed to replicate a typical IBM customer workload usage in the marketplace. Results may vary. 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. The total number of IBM Z cores needed to deliver the workloads was 28. Both the x86 and z15 environments had access to the same storage array. Total Cost of Ownership is defined here to include hardware, software, labor, networking, floor space and energy costs over a period of 5 years. IBM internal hardware list prices were used. x86 server prices were acquired from IDC. IBM software pricing was standard list prices with 20% discount applied. For more details contact the IT Economics team at IBM.
