Consolidate servers for Linux on System z

Linux® on System z® operating system is a native implementation of the Linux operating system. Hosting options include running Linux in one or more logical partitions (LPAR).

Integrated facility for Linux (IFL)

IFLs are System z processors dedicated to running Linux operating system workloads either natively, or under virtualization software, depending on your needs. IFLs enable you to consolidate and centrally manage Linux resources on System z.

Logical partition (LPAR) mode

Linux operating system can run in LPARs and communicate with other Linux partitions using TCP/IP connections.

The horizontal scalability in a large Linux environment is limited by the number of LPARs that can be created. Running Linux in LPARs may be best if you are running a small number of Linux images, and those images will each be using a large amount of processing power, or will require a very large amount of dedicated memory. This ensures that the images will not have underutilized resources allocated to them.
