IBM SmartCloud
IBM cloud computing is a set of cloud computing services for business offered by the information technology company IBM. IBM Cloud includes infrastructure as a service (IaaS), software as a service (SaaS) and platform as a service (PaaS) offered through public, private and hybrid cloud delivery models, in addition to the components that make up those clouds. Overview IBM offers three hardware platforms for cloud computing. These platforms offer built-in support for virtualization. IBM also offers a virtualization application infrastructure, Websphere, which supports programming models and open standards for virtualization. The management layer of the IBM cloud framework includes IBM Tivoli middleware. Management tools provide capabilities to regulate images with automated provisioning and de-provisioning, monitor operations and meter usage while tracking costs and allocating billing. The last layer of the framework provides integrated workload tools. Workloads (in the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Closed Source Software
Proprietary software is software that is deemed within the free and open-source software to be non-free because its creator, publisher, or other rightsholder or rightsholder partner exercises a legal monopoly afforded by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting his or her freedoms. It is often contrasted with open-source or free software. For this reason, it is also known as non-free software or closed-source software. Types Origin Until the late 1960s computers—large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than sold. Service and all software available were usually supplied by manufacturers without separate charge until 1969. Computer vendors us ...

Tivoli Software
Tivoli Software encompasses a set of products originally developed by Tivoli Systems Inc. IBM bought the company and ran the operation as its Tivoli Software division. Additional products were acquired and run under the Tivoli portfolio brand. IBM began phasing out use of the Tivoli brand in 2013 and by 2016 had moved the portfolio products into a revised and rebranded hierarchy. History of Tivoli brand Tivoli Systems Inc. was founded in Austin, Texas in 1989 by Bob Fabbio and quickly joined by Peter Valdes, Todd Smith and Steve Marcie; all were former IBM employees. Bob Fabbio in an interview indicated the purpose was to provide systems management on systems from a diverse set of vendors while at IBM he had been directed to focus on IBM products only. As an independent software vendor Tivoli Systems developed and sold Tivoli Management Environment (TME) "systems management" software and services. The then CEO Frank Moss saw the company listed on NASDAQ in March 1995 and ... [...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 of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Live Migration
Live migration refers to the process of moving a running virtual machine (VM) or application between different physical machines without disconnecting the client or application. Memory, storage, and network connectivity of the virtual machine are transferred from the original guest machine to the destination. The time between stopping the VM or application on the source and resuming it on destination is called 'downtime'. When the downtime of a VM during live migration is small enough that it is not noticeable by the end user, it is called a 'seamless' live migration. Live migration of Virtual Machines Two techniques for moving the virtual machine's memory state from the source to the destination are pre-copy memory migration and post-copy memory migration. Pre-copy memory migration Pre-copy phase In pre-copy phase, the Hypervisor copies all the memory pages from source to destination while the VM is still running on the source. If some memory pages change (become 'dirty') d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 partitio ...

Power Systems
An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the Electric generator, generators that supply the power, the electric power transmission, transmission system that carries the power from the generating centers to the Distribution board, load centers, and the electric power distribution, distribution system that feeds the power to nearby homes and industries. Smaller power systems are also found in industry, hospitals, commercial buildings, and homes. A single line diagram helps to represent this whole system. The majority of these systems rely upon three-phase electric power, three-phase AC power—the standard for large-scale power transmission and distribution across the modern world. Specialized power systems that do not always rely upon thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Apr ...

RS/6000
The RISC System/6000 (RS/6000) is a family of Reduced instruction set computer, RISC-based Unix Server (computing), 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 was the first computer line to see the use of IBM's IBM Power microprocessors, POWER and PowerPC based microprocessors. In October 2000, the RS/6000 brand was retired for POWER-based servers and replaced by the pSeries, eServer pSeries. Workstations continued under the RS/6000 brand until 2002, when new POWER-based workstations were released under the IntelliStation POWER brand. History The first RS/6000 models used the Micro Channel architecture, Micro Channel bus, later models used Peripheral Component Interconnect, PCI. Some later models conformed to the PReP and Common Hardware Reference Platform, CHRP standard platforms, which were co-developed with Apple Inc., Apple and Motorola, with Open Firmware. The plan was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypervisor
A hypervisor (also known as a virtual machine monitor, VMM, or virtualizer) is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a ''host machine'', and each virtual machine is called a ''guest machine''. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Unlike an emulator, the guest executes most instructions on the native hardware. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system–level virtualization, where all instances (usually called ''containers'') must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the s ...

CP-67
CP-67 was the ''control program'' portion of CP/CMS, a virtual machine operating system developed for the IBM System/360-67 by IBM's Cambridge Scientific Center. It was a reimplementation of their earlier research system CP-40, which ran on a one-off customized S/360-40. CP-67 was later reimplemented (again) as CP-370, which IBM released as VM/370 in 1972, when virtual memory was added to the System/370 series. Details on the development and circumstances of CP-67 can be found in the article History of CP/CMS This article covers the History of CP/CMS — the historical context in which the IBM time-sharing virtual machine operating system was built. CP/CMS development occurred in a complex political and technical ''milieu''. Historical notes, below, ....

IBM CP-40
CP-40 was a research precursor to CP-67, which in turn was part of IBM's then-revolutionary CP 67CMS – a virtual machine/virtual memory time-sharing operating system for the IBM System/360 Model 67, and the parent of IBM's VM family. CP-40 ran multiple instances of client operating systems – particularly CMS, the ''Cambridge Monitor System'', built as part of the same effort. Like CP-67, CP-40 and the first version of CMS were developed by IBM's Cambridge Scientific Center (CSC) staff, working closely with MIT researchers at Project MAC and Lincoln Laboratory. CP-40/CMS production use began in January 1967. CP-40 ran on a unique, specially modified IBM System/360 Model 40. Project goals CP-40 was a one-off research system. Its declared goals were: * Provide research input to the System/360 Model 67 team working in Poughkeepsie, who were breaking new ground with the as-yet-unproven concept of virtual memory. * Support CSC's time-sharing requirements in Cambridge.
