IBM Power Systems
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''. In A ...

IBM I
IBM i (the ''i'' standing for ''integrated'') is an operating system developed by IBM for IBM Power Systems. It was originally released in 1988 as OS/400, as the sole operating system of the IBM AS/400 line of systems. It was renamed to i5/OS in 2004, before being renamed a second time to IBM i in 2008. It is an evolution of the System/38 CPF operating system, with compatibility layers for System/36 SSP and AIX applications. It inherits a number of distinctive features from the System/38 platform, including the Machine Interface, the implementation of object-based addressing on top of a single-level store, and the tight integration of a relational database into the operating system. History Origin OS/400 was developed alongside the AS/400 hardware platform beginning in December 1985. Development began in the aftermath of the failure of the Fort Knox project, which left IBM without a competitive midrange system. During the Fort Knox project, a skunkworks project was st ...

PureSystems
PureSystems is an IBM product line of factory pre-configured components and servers also being referred to as an "Expert Integrated System". The centrepiece of PureSystems is the ''IBM Flex System Manager'' in tandem with the so-called "Patterns of Expertise" for the automated configuration and management of PureSystems. PureSystems can host four different operating systems (AIX, IBM i, Linux, Windows) and five hypervisors (Hyper-V, KVM, PowerVM, VMware, Xen) on two different instruction set architectures: Power ISA and x86. PureSystems is marketed as a converged system, which packages multiple information technology components into a single product. Architecture The architecture itself is called IBM Flex System. It aims at managing hybrid cloud infrastructure environments "out of the box". The basic intention is for the combination of integrated hardware and software that can be easily maintained. A similar concept had already been introduced with the IBM AS/400. Today, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM BladeCenter
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. History Introduced in 2002, based on engineering work started in 1999, the IBM eServer BladeCenter was relatively late to the blade server market. It differed from prior offerings in that it offered a range of x86 Intel server processors and input/output (I/O) options. The naming was changed to IBM BladeCenter in 2005. In February 2006, IBM introduced the BladeCenter H with switch capabilities for 10 Gigabit Ethernet and InfiniBand 4X. A web site called Blade.org was available for the blade computing community through about 2009. In 2012, the replacement Flex System was introduced. Enclosures IBM BladeCenter (E) The original IBM BladeCenter was later marketed as BladeCenter E. Power supplies have been upgraded through the life of the chassis from the original 1200 to 1400, 1800, 2000 and 2320 watt. The BladeCent ...

PowerVM
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. Description IBM PowerVM has the following components: * A "VET" code, which activates firmware required to support resource sharing and other features. * Installation media for the Virtual I/O Server (VIOS), which is a service partition providing sharing services for disk and network adapters. * Installation media for Lx86, x86 binary translation software, which allows Linux applications compiled for the Intel x86 platform to run in POWER-emulation mode. A supported Linux distribution is a co-requisite for use of this feature. IBM PowerVM comes in three editions: IBM PowerVM Express * Only supported on "Express" servers (e.g. Power 710/730, 720/740, 750 and Power Blades). * Limited to three partiti ...

PERCS
PERCS (Productive, Easy-to-use, Reliable Computing System) is IBM's answer to DARPA's High Productivity Computing Systems (HPCS) initiative. The program resulted in commercial development and deployment of the Power 775, a supercomputer design with extremely high performance ratios in fabric and memory bandwidth, as well as very high performance density and power efficiency. IBM officially announced the Power 775 on July 12, 2011 and started to ship systems in August 2011. Background The HPCS program was a three phase research and development effort. IBM was one of three companies, along with Cray and Sun Microsystems, that received the HPCS grant for Phase II. In this phase, IBM collaborated with a consortium of 12 universities and the Los Alamos National Lab to pursue an adaptable computing system with the goal of commercial viability of new chip technology, new computer architecture, operating systems, compiler and programming environments. IBM was chosen for Phase III i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-performance Computing
High-performance computing (HPC) uses supercomputers and computer clusters to solve advanced computation problems. Overview HPC integrates systems administration (including network and security knowledge) and parallel programming into a multidisciplinary field that combines digital electronics, computer architecture, system software, programming languages, algorithms and computational techniques. HPC technologies are the tools and systems used to implement and create high performance computing systems. Recently, HPC systems have shifted from supercomputing to computing clusters and grids. Because of the need of networking in clusters and grids, High Performance Computing Technologies are being promoted by the use of a collapsed network backbone, because the collapsed backbone architecture is simple to troubleshoot and upgrades can be applied to a single router as opposed to multiple ones. The term is most commonly associated with computing used for scientific research or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endianness
In computing, endianness, also known as byte sex, is the order or sequence of bytes of a word of digital data in computer memory. Endianness is primarily expressed as big-endian (BE) or little-endian (LE). A big-endian system stores the most significant byte of a word at the smallest memory address and the least significant byte at the largest. A little-endian system, in contrast, stores the least-significant byte at the smallest address. Bi-endianness is a feature supported by numerous computer architectures that feature switchable endianness in data fetches and stores or for instruction fetches. Other orderings are generically called middle-endian or mixed-endian. Endianness may also be used to describe the order in which the bits are transmitted over a communication channel, e.g., big-endian in a communications channel transmits the most significant bits first. Bit-endianness is seldom used in other contexts. Etymology Danny Cohen introduced the terms ''big-en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Third-party derivatives can be built and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
POWER6
The POWER6 is a microprocessor developed by IBM that implemented the Power ISA v.2.03. 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 (hence "ipz" in the acronym: 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 POWER6 is a dual-core processor. Each core is capable ...
