Red Hat Enterprise Linux 6.9 runs on System z9 or later IBM mainframe systems.
The installation process assumes that you are familiar with the IBM System z and can set up logical partitions
(LPARs) and z/VM guest virtual machines. For additional information on System z, refer to http://www.ibm.com/systems/z
For installation of Red Hat Enterprise Linux on System z, Red Hat supports DASD and FCP storage devices.
Before you install Red Hat Enterprise Linux, you must decide on the following:
Decide whether you want to run the operating system on an LPAR or as a z/VM guest operating system.
Decide if you need swap space and if so how much. Although it is possible (and recommended) to assign enough memory to z/VM guest virtual machine and let z/VM do the necessary swapping, there are cases where the amount of required RAM is hard to predict. Such instances should be examined on a case-by-case basis. Refer to Section 23.15.5, “Recommended Partitioning Scheme”
Decide on a network configuration. Red Hat Enterprise Linux 6.9 for IBM System z supports the following network devices:
Real and virtual Open Systems Adapter (OSA)
Real and virtual HiperSockets
LAN channel station (LCS) for real OSA
You require the following hardware:
Disk space. Calculate how much disk space you need and allocate sufficient disk space on DASDs or SCSI disks. You require at least 2 GB for a server installation, and 5 GB if you want to install all packages. You also require disk space for any application data. After the installation, more DASD or SCSI disk partitions may be added or deleted as necessary.
The disk space used by the newly installed Red Hat Enterprise Linux system (the Linux instance) must be separate from the disk space used by other operating systems you may have installed on your system.
RAM. Acquire 1 GB (recommended) for the Linux instance. With some tuning, an instance might run with as little as 512 MB RAM.
