Red Hat Enterprise Linux support for mainframe systems allows customers to deploy a common operating system across their entire IT infrastructure. From the laptop to the mainframe.
What makes Red Hat Enterprise Linux the appropriate solution for mainframe environments?
Red Hat Enterprise Linux subscriptions are available for IBM System z mainframe systems on a per processor basis [1] Because common Red Hat Enterprise Linux source code is used for all architectures, the new features provided by version 5 are available to mainframe customers. Note that in a mainframe environment, virtualization is provided by hardware partitioning capabilities rather than the Red Hat Enterprise Linux kernel.
Red Hat Enterprise Linux Advanced Platform is not required or available for mainframe systems because the bundled technologies (kernel-level virtualization, storage virtualization, and high availability clustering) are provided separately.

[1] With a System z Red Hat Enterprise Linux subscription, an unlimited number of Enterprise Linux images can be run per processor. Typically this processor will be referred to as an Integrated Facility for Linux (IFL). If one IFL is used, one subscription is required. If two IFLs are used, two subscriptions are required, and so on. A System z subscription provides an allocation of Red Hat Enterprise Linux entitlements and each includes the Red Hat Network Update module so that software updates and security errata can be received per image. Note that the choice to logically partition an IFL does not affect the price of a subscription.
[2] IBM System z subscriptions include the ability to run and support up 1000 Red Hat Enterprise Linux instances/images per subscription per engine.
