Superior RAS on Linux
Linux on Power offers enhanced RAS capabilities not commonly found in other 32- and 64-bit Linux x86 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 all other aspects.
With IBM Power processor-based systems you get RAS characteristics not commonly found in server families running the Linux operating system and your mission-critical applications see a higher level of support than in 64-bit x86 Linux environments. SUSE Linux Enterprise Server 12 for IBM Power on IBM POWER8 exposes key RAS tenets of the Power platform, supporting IBM Power’s RAS capabilities such as hardware redundancy and resource affinity.
Supported PowerLinux technologies and their associated benefits include:
- Virtualization—Through PowerKVM, SUSE Linux Enterprise Server 12 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 IBM Power provides support for CPU, memory and I/O affinity. SUSE Linux Enterprise Server 12 on IBM POWER8 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.
