SUSE Linux on POWER offers enhanced RAS capabilities not commonly found in other server environments.
UNIX is known for its reliability, availability and serviceability (RAS). Advanced Linux systems, such as SUSE Linux Enterprise Server, have closed that gap to deliver RAS on par with UNIX, and outpaced traditional UNIX systems in many other aspects.
With IBM POWER processor-based systems you get RAS characteristics not commonly found in server families running the Linux operating system, and capabilities designed for the demands of mission–critical workloads. SUSE Linux Enterprise Server 12 for POWER on IBM POWER8 exposes key RAS tenets of the POWER platform, supporting RAS capabilities such as hardware redundancy and resource affinity.
Supported POWER technologies for Linux and their associated benefits include:
- Virtualization—Through PowerKVM, SUSE Linux Enterprise Server 12 for POWER supports the ability of Linux to manage virtual memory like the memory in a typical physical Linux server. This includes memory overcommit and page caching.
- Shared resource pools—Like its predecessors, SUSE Linux Enterprise Server 12 on POWER provides support for CPU, memory and I/O affinity. For POWER8 processor-based systems, SUSE Linux Enterprise Server 12 also supports EEH memory error recovery and memory sharing through KVM Kernel Memory Sharing, allowing you to maximize utilization of your hardware resources.
- Live VM migration—Maximize your application availability by moving your workload to better balance system resources and uptime through live virtual machine migration with PowerKVM.
