IBM XIV Storage System
The IBM XIV Storage System was a line of cabinet-size disk storage servers. The system is a collection of modules, each of which is an independent computer with its own memory, interconnections, disk drives, and other subcomponents, laid out in a grid and connected together in parallel using either InfiniBand (third generation systems) or Ethernet (second generation systems) connections. Each module has an x86 CPU and runs a software platform consisting largely of a modified Linux kernel and other open source software. Description Traditional storage systems distribute a volume across a subset of disk drives in a clustered fashion. The XIV storage system distributes volumes across all modules in 1 MiB chunks (partitions) so that all of the modules' resources are used evenly. For robustness, each logical partition is stored in at least two copies on separate modules, so that if a part of a disk drive, an entire disk drive, or an entire module fails, the data is still available ...

IBM FlashSystem
IBM FlashSystem is an IBM Storage enterprise system that stores data on flash memory. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 IBM acquisition of Texas Memory Systems. According to Gartner, IBM was the number one all-flash storage array vendor in 2014 selling over 2,100 FlashSystems totaling 62 petabytes (PB) of capacity. The IBM FlashSystem commanded 33% of the total all-flash capacity sold by all vendors for the year. As of February 12, 2020 the FlashSystem brand has replaced both the Storwize and XIV brands in IBM. History Origin The IBM FlashSystem architecture was originally developed by Texas Memory Systems (TMS) as their RamSan product line. TMS was a small private company founded in 1978 and based in Houston, Texas that supplied solid-state drive products to the market longer than any other company. The TMS RamSan line of enterprise solid state storage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel Xeon
Xeon ( ) is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded system markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for ECC memory, higher core counts, more PCI Express lanes, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware exceptions through the Machine Check Architecture. They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the machine-check exception (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the Ultra Path Interconnect (UPI) bus. Overview The ''Xeon'' brand has been maint ...

Data Storage
Data storage is the recording (storing) of information (data) in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media. Biological molecules such as RNA and DNA are considered by some as data storage. Recording may be accomplished with virtually any form of energy. Electronic data storage requires electrical power to store and retrieve data. Data storage in a digital, machine-readable medium is sometimes called ''digital data''. Computer data storage is one of the core functions of a general-purpose computer. Electronic documents can be stored in much less space than paper documents. Barcodes and magnetic ink character recognition (MICR) are two ways of recording machine-readable data on paper. Recording media A recording medium is a physical material that holds information. Newly created information is distributed and can be stored in four storage media–print, film, magnetic, and optical–and seen or ...

Footnotes
A note is a string of text placed at the bottom of a page in a book or document or at the end of a chapter, volume, or the whole text. The note can provide an author's comments on the main text or citations of a reference work in support of the text. Footnotes are notes at the foot of the page while endnotes are collected under a separate heading at the end of a chapter, volume, or entire work. Unlike footnotes, endnotes have the advantage of not affecting the layout of the main text, but may cause inconvenience to readers who have to move back and forth between the main text and the endnotes. In some editions of the Bible, notes are placed in a narrow column in the middle of each page between two columns of biblical text. Numbering and symbols In English, a footnote or endnote is normally flagged by a superscripted number immediately following that portion of the text the note references, each such footnote being numbered sequentially. Occasionally, a number between brack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone.
