High performance and throughput with support for the latest technology advances in SIMD (Single Instruction, Multiple Data) and SMT (Simultaneous Multithreading) across the full range of IBM Z and LinuxONE systems.
Increased security and data protection by supporting the latest cryptographic acceleration for secure-key operations and new hardware assists for fast data encryption.
Enhanced virtualization capabilities to boost resource utilization using KVM and z/VM, giving you the ability to create several virtual machines that run on a single processor and handle multiple workloads. This lets you reduce or eliminate the need to buy more hardware and lets you consolidate physical systems to shrink your data center footprint and simplify maintenance for your IT staff.
Advanced RAS capabilities increase reliability and reduce costs, providing extra dimensions of availability and ensuring the highest levels of security while reducing your planned and unplanned downtime and supporting the legendary RAS characteristics of IBM z Systems.
Improved operational efficiency with tools you won’t find anywhere else and by taking advantage of the networking and communications features for OpenFabrics Enterprise Distribution, shared memory communications and enhanced HiperSockets support. Our systems management tools dramatically reduce tedious, complicated and labor-intensive maintenance.
SUSE Linux Enterprise Server for IBM Z and LinuxONE runs on the following platforms:
- IBM zEnterprise EC12 (zEC12) (2827)
- IBM zEnterprise BC12 (zBC12) (2828)
- IBM z13 (2964)
- IBM z13s (2965)
- IBM LinuxONE Emperor (2964
- IBM LinuxONE Rockhopper (2965)
- IBM z14 (3906)
- IBM z14 ZR1 (3907)
- IBM LinuxONE Emperor II (3906)
- IBM LinuxONE Rockhopper II (3907)
A network connection is needed to communicate with your SUSE Linux Enterprise Server system. This can be one or more of the following connections or network cards:
- OSA Express Ethernet (including Fast and Gigabit Ethernet)
- HiperSockets or Guest LAN
- 10 GBE, vSwitch
- RoCE (RDMA over Converged Ethernet)
The following interfaces are still included, but are no longer supported:
- CTC (or virtual CTC)
- IP network interface for IUCV
For installations under KVM make sure the following requirements are met to enable the VM Guest to access the network transparently:
- The virtual network interface is connected to a host network interface
- The host network interface is connected to a network in which the virtual server will participate
The disk requirements depend largely on the installation. Commonly, you need more space than the installation software itself needs to have a system that works properly. Minimal requirements for different selections are:
- 1.5 GB for text mode installation
- 2.5 GB for minimal system installation
- 3 GB for GNOME Desktop installation
- 4 GB for all patterns installation
- 10 GB recommended minimum (no Btrfs snapshots)
- 16 GB required minimum (with Btrfs snapshots)
- 32 GB recommended minimum (with Btrfs snapshots)
Different installation methods have different memory requirements during installation. After installation is complete, the system administrator may reduce memory to the desired size. SUSE recommends using:
- 1 GB for installation under z/VM or KVM
- 1 GB for installation under LPAR
For installation from NFS, FTP or SMB installation sources or whenever VNC is used, 512 MB of memory is required as a minimum. Otherwise, the installation attempt is likely to fail. Further note that the number of devices visible to the z/VM guest or LPAR image affects memory requirements. Installation with hundreds of accessible devices (even if unused for the installation) may require more memory.
