z/VM and Linux on Z

The legend lives on

The legendary reliability of IBM’s mainframes makes these machines preferred choice for large customers requiring solid 24/7 performance. They scale to huge sizes and offer mind-boggling performance, especially working with large (read: large) databases.

They can be expensive to get and run, though. And if that makes you think quality services around z/VM and Linux on Z are expensive, please do call us so we can prove otherwise for you.

Ever since IBM introduced IFL in 2000, mainframe customers have used it to harness the power and reliability of mainframe boxes at a much lower cost.

Linux on Z runs directly on an IFL processor or on top of z/VM, and either way channels the benefits of a superb hardware platform, fast access to storage, huge volumes, and uptimes in the range of multiple 9s after the 99.

Additionally, consolidating software licences priced per core from Intel on Linux on Z can offer substantial savings. Examples would include Oracle database, WebSphere Application Server and many other systems similarly priced.

In a similar vein migrating licences from z/OS to Linux on Z can also lower licensing fees a lot.


We’ve built and are maintaining number of z/VM-based Linux on Z installations, which customers use to run business-critical 24/7 systems, some near real-time.

Our services include:
  • Planning new z/VM installations to host Linux on Z systems.
  • Planning new Linux on Z installations on bare IFLs.
  • Implementation of z/VM installations to host Linux on Z systems.
  • Implementation of Linux on Z on bare IFLs or on top of z/VM installations.
  • Implementation of monitoring systems for Linux on Z installations.
  • Monitoring and maintenance of 24×7 production installations of z/VM and Linux on Z systems.
  • Providing 24×7 aggressive SLA levels.

If you have a mainframe and do not use it to run Linux on Z or need additional administration resource, do call us. You’ll be glad you did.
