PSeries
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. History The previous RS/6000 line was originally a line of workstations and servers. The first System p server line was named the ''e''Server 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 ''e''Server p5. 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IBM RS/6000
The RISC System/6000 is a family of RISC-based (Reduced Instruction Set Computer-based) Unix servers, workstations and supercomputers made by IBM in the 1990s. The RS/6000 family replaced the IBM RT PC computer platform in February 1990 and is the first computer line to see the use of IBM's POWER and PowerPC based microprocessors. In October 2000, the RS/6000 brand was retired for POWER-based servers and replaced by the eServer pSeries. Workstations continued under the RS/6000 brand until 2002, when new POWER/-based workstations were released under the IntelliStation POWER/ brand. The RS/6000 floating-point execution unit (FPU) enabled major improvements in the speed and accuracy of floating-point operations. The key feature of the FPU was introducing the MAF (multiply-add fused) operation, which has since become standard in most modern processors.

IBM AS/400
The IBM AS/400 (Application System/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, an estimated 111,000 installations existed 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. A key concept in the AS/400 platform is IBM i#TIMI, Technology Independent Machine Interface (TIMI), a platform-independent instruction set architecture (ISA) that is translated to native machine language instructions. The platform has used this capability to change the underlying processor architecture without breaking application compatibility. Early systems were based on a 48-bit Complex instruction set computer, CISC instruction set architecture known as the ''Internal Microprogrammed Interface'' (IMPI), original ...

EServer
IBM eServer was a family of computer servers from IBM. Announced in 2000, it combined the various IBM server brands (AS/400, Netfinity, RS/6000, S/390) under one brand. The various sub-brands were at the same time rebranded from: *IBM RS/6000 to IBM eServer pSeries, p for POWER *IBM AS/400 to IBM eServer iSeries, i for Integrated *IBM Netfinity to IBM eServer xSeries, x for eXtended architecture (with respect to "commodity" Intel-based servers) *IBM System/390 was replaced by the 64-bit IBM eServer zSeries, z for Zero downtime. The RS/6000 SP supercomputer line was replaced by Blue Gene platform. Discontinuation In 2005, IBM announced a new brand, IBM System, as an umbrella for all IBM server and storage brands. The rebranding was completed in 2006 when the IBM xSeries became the IBM System x (later the Lenovo System x). *IBM eServer zSeries became IBM System z *IBM eServer pSeries became IBM System p The IBM System p is a high-end line of RISC ( Power)/UNIX-based servers. ...

IBM Power Systems
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. History IBM had two distinct POWER- and PowerPC-based hardware lines since the early 1990s: * Servers running processors based on the IBM PowerPC-AS architecture in the AS/400 family (later known as iSeries, then System i) running OS/400 (later known as i5/OS, and now IBM i) * Servers and workstations using POWER and PowerPC processors in the RS/6000 family (later known as pSeries, then System p), running IBM AIX and Linux on Power. After the introduction of the POWER4 processor in 2001, there was little difference between both the "p" and the "i" hardware; the only differences were in the software and services offerings. With the introduction of the POWER5 processor in 2004, even the product numbering was synchronized. The ''System i5 570'' was virtually identical to the ''System p5 570''. ...

IBM Power Microprocessors
Power microprocessors (originally POWER prior to Power10) are designed and sold by IBM for Server (computing), 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, IBM AS/400, AS/400, pSeries, iSeries, System p, System i, and IBM Power Systems, 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 Groupe Bull, Bull and Hitachi. The Power family was originally developed in the late 1980s, and remains under active development. In the beginning, they implemented the IBM POWER Instruction Set Architecture, POWER instruction set architecture (ISA), which evolved into PowerPC and later into Power ISA. In August 2019, IBM announced it would open source the Power ISA. As part of the move, it was also announced that administration of ...

AIX Operating System
AIX (pronounced ) 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. Background Originally released for the IBM RT PC RISC workstation in 1986, AIX has supported a wide range of hardware platforms, including the IBM RS/6000 series and later Power and PowerPC-based systems, IBM System i, System/370 mainframes, PS/2 personal computers, and the Apple Network Server. Currently, it is supported on IBM Power Systems alongside IBM i and Linux. AIX is based on UNIX System V with 4.3BSD-compatible extensions. It is certified to the UNIX 03 and UNIX V7 specifications of the Single UNIX Specification, beginning with AIX versions 5.3 and 7.2 TL5, respectively. Older versions were certified to the UNIX 95 and UNIX 98 specifications. AIX was the first operating system to imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Logical Partitioning
Dynamic Logical Partitioning (DLPAR), is the capability of a logical partition (LPAR) to be reconfigured dynamically, without having to shut down the operating system that runs in the LPAR. DLPAR enables memory, CPU capacity, and I/O interfaces to be moved nondisruptively between LPARs within the same server. DLPAR has been supported by the operating systems AIX and IBM i on almost all POWER4 and follow-on POWER systems since then. The Linux kernel for POWER also supported DLPAR, but its dynamic reconfiguration capabilities were limited to CPU capacity and PCI devices, but not memory. In October 2009, seven years after the AIX announcement of DLPAR of memory, CPU and IO slots, Linux finally added the capability to DLPAR memory on POWER systems. The fundamentals of DLPAR are described in the IBM Systems Journal paper titled: "Dynamic reconfiguration: Basic building blocks for autonomic computing on IBM pSeries Servers. Later on, the POWER5 processor added enhanced DLPAR capabiliti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
POWER6
The POWER6 is a microprocessor developed by IBM that implemented the Power ISA#Power ISA v.2.05, Power ISA v.2.05. When it became available in systems in 2007, it succeeded the POWER5#POWER5+, 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 (hence "ipz" in the acronym: IBM AS/400, iSeries, pSeries, and zSeries). History POWER6 was described at the International Solid-State Circuits Conference (ISSCC) in February 2006, and additional details were added at the Microprocessor Forum in October 2006 and at the next ISSCC in February 2007. It was formally announced on May 21, 2007. It was released on June 8, 2007 at speeds of 3.5, 4.2 and 4.7 GHz, but the company has noted prototypes have reached 6 GHz. POWER6 reached first silicon in the middle of 2005, and was bumped to 5.0 GHz in May 2008 with the introduction of the P595. Description The POWE ...

Supercomputer
A supercomputer is a type of computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2022, supercomputers have existed which can perform over 1018 FLOPS, so called Exascale computing, exascale supercomputers. For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (1011) to tens of teraFLOPS (1013). Since November 2017, all of the TOP500, world's fastest 500 supercomputers run on Linux-based operating systems. Additional research is being conducted in the United States, the European Union, Taiwan, Japan, and China to build faster, more powerful and technologically superior exascale supercomputers. Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in various fields, ...

Random Access Memory
Random-access memory (RAM; ) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks and magnetic tape), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. In today's technology, random-access memory takes the form of integrated circuit (IC) chips with MOS (metal–oxide–semiconductor) memory cells. RAM is normally associated with volatile types of memory where stored information is lost if power is removed. The two main types of volatile random-access semiconductor memory are static ...
