What is SUSE Linux Enterprise Server for POWER 12?

SUSE Linux Enterprise Server for POWER is an enterprise-grade Linux distribution optimized for IBM Power Systems and designed to deliver increased reliability, reduce costs for mission-critical applications, provide a high-performance platform to meet increasing business demands and accelerate innovation while improving deployment times. SUSE Linux Enterprise Server for POWER 12 runs in the POWER8 processor’s little-endian mode. Support for little endian mode removes a portability barrier for software application vendors that started out on the x86 and x86-64 platforms. With great tools such as the Open Build Service and SUSE Package Hub, SUSE provides an environment that supports partners, enabling them to bring their latest innovation to the dynamic Linux market on IBM Power Systems.

What is big-endian / little-endian?

Endian or endianness refers to how bytes of a data word are ordered in memory (see http://en.wikipedia.org/wiki/Endianness). Big-endian systems like POWER6, POWER7 and IBM z Systems store the most significant byte in the smallest address consumed by an integer number or address, and the least significant byte is stored in the largest. In contrast, little-endian systems, such as the x86 and x86-64 architectures, are those in which the least significant byte is stored in the smallest address. POWER8 processors can be configured in either big-endian or little-endian mode. Supporting little-endian on Power Systems will simplify source code porting from little-endian x86 Linux applications to little-endian Linux on Power. Data produced by existing x86 Linux applications can be accessed more easily by other little-endian Linux applications. Modern I/O systems (particularly GPUs) assume little-endian access models.

Can I run SUSE Linux Enterprise Server for POWER 12 on POWER8?

Yes. SUSE Linux Enterprise Server 12 will operate the POWER8 processor in little-endian mode, which has no effect on the functionality of the OS or the features provided by the processor. SUSE Linux Enterprise Server for POWER 12 takes full advantage of POWER8’s Simultaneous Multithreading (SMT) and other hardware advances made available in the modern 4.4 Linux kernel. POWER8 supports SUSE Linux Enterprise Server for POWER as a KVM guest in addition to support for PowerVM. SUSE’s industry-leading features like Full System Rollback, Linux containers with Docker, Modules and Package Hub are supported on POWER8-based servers.

Can I run my SAP applications on SUSE Linux Enterprise Server for POWER 12 and POWER8?

Yes, most SAP NetWeaver and other applications will run on POWER8-based servers and SUSE Linux Enterprise Server for POWER 12, as long as little-endian mode is supported by that application. You should be aware SAP has certified SUSE Linux Enterprise Server for SAP applications 11 SP4 as the only operating system for IBM Power Systems to run SAP HANA.
