The IBM System p is a high-end line of RISC (Power)/UNIX-based servers. It was the successor of the RS/6000 line, and predecessor of the IBM Power Systems server series.
The previous RS/6000 line was originally a line of workstations and servers. The first System p server line was named the eServer pSeries in 2000 as part of the e-Server branding initiative.
In 2004, with the advent of the POWER5 processor, the server family was rebranded the eServer p5. [1]
In 2005, following IBM's move to streamline its server and storage brands worldwide, and incorporating the "System" brand with the Systems Agenda, the family was again renamed to System p5. The System p5 now encompassed the IBM OpenPower product line.
In 2007, after the introduction of the POWER6 processor models, the last rename under the System p brand dropped the p (numbered) designation.
In April 2008, IBM announced a rebranding of the System p and its unification with the mid-range System i platform. The resulting product line was called IBM Power Systems .
Whereas the previous RS/6000 line used a mix of early POWER and PowerPC processors, when pSeries came along, this had evolved into RS64-III and POWER3 across the board—POWER3 for its excellent floating-point performance and RS64 for its scalability, throughput, and integer performance.
IBM developed the POWER4 processor to replace both POWER3 and the RS64 line in 2001. After that, the differences between throughput and number crunching-optimized systems no longer existed. Since then, System p machines evolved to use the POWER5 but also the PowerPC 970 for the low-end and blade systems.
The last System p systems used the POWER6 processor, such as the POWER6-based System p 570 and the JS22 blade. In addition, during the SuperComputing 2007 (SC07) conference in Reno, IBM introduced a new POWER6-based System p 575 with 32 POWER6 cores at 4.7 GHz and up to 256 GB of RAM with water cooling.
All IBM System p5 and IBM eServer p5 machines support DLPAR (Dynamic Logical Partitioning) with Virtual I/O and Micro-partitioning.

System p generally uses the AIX operating system and, more recently, 64-bit versions of the Linux operating system.
The IBM p690 was, at the time of its release in late 2001, the flagship of IBM's high-end Unix servers during the POWER4 era of processors. It was built to run IBM AIX Unix, although it is possible to run a version of Linux minus some POWER4-specific features.
It could support up to 32 (1.5, 1.7 or 1.9 GHz) POWER4+ processors and 1 TB of RAM, which weighs well over 1000 kg. It was used in a supercomputer at Forschungszentrum Jülich in 2004, and was discontinued in late 2005. [5]
Released in 2004. [6]
System p was rebranded to Power Systems in 2008.
OpenPower was the name of a range of servers in the System p line from IBM. They featured IBM's POWER5 CPUs and run only 64-bit versions of Linux. IBM's own UNIX variant, AIX is not supported since the OpenPower servers are not licensed for this operating system.
There were two models available, with a variety of configurations.
Before 2005, OpenPower belonged to the eServer product line but were eventually rolled into the IBM's Power Systems product portfolio.
AIX is a series of proprietary Unix operating systems developed and sold by IBM since 1986. The name stands for "Advanced Interactive eXecutive". Current versions are designed to work with Power ISA based server and workstation computers such as IBM's Power line.
The IBM AS/400 is a family of midrange computers from IBM announced in June 1988 and released in August 1988. It was the successor to the System/36 and System/38 platforms, and ran the OS/400 operating system. Lower-cost but more powerful than its predecessors, the AS/400 was extremely successful at launch, with an estimated 111,000 installed by the end of 1990 and annual revenue reaching $14 billion that year, increasing to 250,000 systems by 1994, and about 500,000 shipped by 1997.
The Power Mac G5 is a series of personal computers designed, manufactured, and sold by Apple Computer, Inc. from 2003 to 2006 as part of the Power Mac series. When introduced, it was the most powerful computer in Apple's Macintosh lineup, and was marketed by the company as the world's first 64-bit desktop computer. It was also the first desktop computer from Apple to use an anodized aluminum alloy enclosure, and one of only three computers in Apple's lineup to utilize the PowerPC 970 CPU, the others being the iMac G5 and the Xserve G5.
The PowerPC 970, PowerPC 970FX, and PowerPC 970MP are 64-bit PowerPC CPUs from IBM introduced in 2002. Apple branded the 970 as PowerPC G5 for its Power Mac G5.
The POWER5 is a microprocessor developed and fabricated by IBM. It is an improved version of the POWER4. The principal improvements are support for simultaneous multithreading (SMT) and an on-die memory controller. The POWER5 is a dual-core microprocessor, with each core supporting one physical thread and two logical threads, for a total of two physical threads and four logical threads.
The POWER4 is a microprocessor developed by International Business Machines (IBM) that implemented the 64-bit PowerPC and PowerPC AS instruction set architectures. Released in 2001, the POWER4 succeeded the POWER3 and RS64 microprocessors, enabling RS/6000 and eServer iSeries models of AS/400 computer servers to run on the same processor, as a step toward converging the two lines. The POWER4 was a multicore microprocessor, with two cores on a single die, the first non-embedded microprocessor to do so. POWER4 Chip was first commercially available multiprocessor chip. The original POWER4 had a clock speed of 1.1 and 1.3 GHz, while an enhanced version, the POWER4+, reached a clock speed of 1.9 GHz. The PowerPC 970 is a derivative of the POWER4.
POWER7 is a family of superscalar multi-core microprocessors based on the Power ISA 2.06 instruction set architecture released in 2010 that succeeded the POWER6 and POWER6+. POWER7 was developed by IBM at several sites including IBM's Rochester, MN; Austin, TX; Essex Junction, VT; T. J. Watson Research Center, NY; Bromont, QC and IBM Deutschland Research & Development GmbH, Böblingen, Germany laboratories. IBM announced servers based on POWER7 on 8 February 2010.
PowerLinux is the combination of a Linux-based operating system (OS) running on PowerPC- or Power ISA-based computers from IBM. It is often used in reference along with Linux on Power, and is also the name of several Linux-only IBM Power Systems.
The POWER6 is a microprocessor developed by IBM that implemented the Power ISA v.2.05. When it became available in systems in 2007, it succeeded the POWER5+ as IBM's flagship Power microprocessor. It is claimed to be part of the eCLipz project, said to have a goal of converging IBM's server hardware where practical.
A logical partition (LPAR) is a subset of a computer's hardware resources, virtualized as a separate computer. In effect, a physical machine can be partitioned into multiple logical partitions, each hosting a separate instance of an operating system.
Micro-Partitioning is a form of logical partitioning which was introduced by IBM on systems using the POWER5 processor, and is also referred to as a shared processor partition, and only differs from a dedicated processor partition in the way CPU utilization is configured and managed by the POWER Hypervisor (PHYP) firmware. All IBM POWER5 and POWER6 systems are partitioned and will run "on top" of the PHYP.
IBM Z is a family name used by IBM for all of its z/Architecture mainframe computers. In July 2017, with another generation of products, the official family was changed to IBM Z from IBM z Systems; the IBM Z family now includes the newest model, the IBM z17, as well as the z16, z15, z14, and z13, the IBM zEnterprise models, the IBM System z10 models, the IBM System z9 models and IBM eServer zSeries models.
Hardware Management Console (HMC) is a Physical / Virtual appliance used to manage IBM Systems including IBM AS/400, IBM System p, IBM System z, and IBM Power Systems. HMC supports command line (ssh) as well as web (https) user interfaces and REST API. Using an HMC, the system administrator can manage many systems and partitions. It can also be used for monitoring and servicing a system.
The IBM BladeCenter was IBM's blade server architecture, until it was replaced by Flex System in 2012. The x86 division was later sold to Lenovo in 2014.
ppc64 is an identifier commonly used within the GNU/Linux, GNU Compiler Collection (GCC) and LLVM free software communities to refer to the target architecture for applications optimized for 64-bit big-endian PowerPC and Power ISA processors.
PowerVM, formerly known as Advanced Power Virtualization (APV), is a chargeable feature of IBM POWER5, POWER6, POWER7, POWER8, POWER9 and Power10 servers and is required for support of micro-partitions and other advanced features. Support is provided for IBM i, AIX and Linux.
IBM Power Systems is a family of server computers from IBM that are based on its Power processors. It was created in 2008 as a merger of the System p and System i product lines.
IBM Power microprocessors are designed and sold by IBM for servers and supercomputers. The name "POWER" was originally presented as an acronym for "Performance Optimization With Enhanced RISC". The Power line of microprocessors has been used in IBM's RS/6000, AS/400, pSeries, iSeries, System p, System i, and Power Systems lines of servers and supercomputers. They have also been used in data storage devices and workstations by IBM and by other server manufacturers like Bull and Hitachi.
The IBM DS8000 series is an IBM storage media platform with hybrid flash and hard disk storage for IBM mainframes and other enterprise grade computing environments.
