IBM C2T
{{short description, Cable chaining technology C2T (an abbreviation for Cable Chaining Technology) is an IBM technology for KVM (keyboard, video, mouse) chaining.Hoskins, Wilson, Winkel, "Exploring IBM @Server Series"CT2 Interconnect Cable Chaining Technology - Google Books C2T, built into some of the IBM's xSeries and Netfinity models, allows daisy-chaining up to forty-two compatible servers in a single rack. Servers are daisy-chained using a special purpose cable which is included with new servers. The final server in the stack is connected to a monitor/keyboard/mouse or a KVM switch using a C2T breakout cable, which provides PS/2 and VGA connectors. The breakout cable was once very expensive to purchase new, but are now obtainable for less than $30 USD The United States dollar (symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially bu ...

IBM System X
System x is a line of x86 servers produced by IBM – and later by Lenovo – as a sub-brand of IBM's ''System'' brand, alongside IBM Power Systems, IBM System z and IBM System Storage. In addition, IBM System x was the main component of the IBM System Cluster 1350 solution. In January 2014, IBM announced the sale of its x86 server business to Lenovo for $2.3 billion, in a sale completed October 1, 2014. History Starting out with the ''PS/2 Server'', then the ''IBM PC Server'', rebranded ''Netfinity'', then ''eServer xSeries'' and finally System x, these servers are distinguished by being based on off-the-shelf x86 CPUs; IBM positioned them as their "low end" or "entry" offering compared to their POWER and Mainframe products. Previously IBM servers based on AMD Opteron CPUs did not share the ''xSeries'' brand; instead they fell directly under the ''e''Server umbrella. However, later AMD Opteron-based servers did fall under the System x brand. Predecessors IBM PS/2 Server * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daisy Chain (electrical Engineering)
In electrical and electronic engineering, a daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring, similar to a garland of daisy flowers. Daisy chains may be used for power, analog signals, digital data, or a combination thereof. The term ''daisy chain'' may refer either to large scale devices connected in series, such as a series of power strips plugged into each other to form a single long line of strips, or to the wiring patterns embedded inside of devices. Other examples of devices which can be used to form daisy chains are those based on Universal Serial Bus (USB), FireWire, Thunderbolt and Ethernet cables. Signal transmission For analog signals, connections usually consist of a simple electrical bus and, especially in the case of a chain of many devices, may require the use of one or more repeaters or amplifiers within the chain to counteract attenuation (the natural loss of energy in such a system). Digital signal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Server (computing)
In computing, a server is a piece of computer hardware or software (computer program) that provides functionality for other programs or devices, called " clients". This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Client–server systems are usually most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledg ...

KVM Switch
A KVM switch (with KVM being an abbreviation for "keyboard, video, and mouse") is a hardware device that allows a user to control multiple computers from one or more sets of keyboards, video monitors, and mice. Name Switches to connect multiple computers to one or more peripherals have had a variety of names. The earliest name was Keyboard Video Switch (KVS). With the advent of the mouse, the Keyboard, Video and Mouse (KVM) switch became popular. The name was introduced by Remigius Shatas, the founder of Cybex, a peripheral switch manufacturer, in 1995. Some companies call their switches Keyboard, Video, Mouse and Peripheral (KVMP). Types With the popularity of USB—USB keyboards, mice, and I/O devices are still the most common devices connected to a KVM switch. The classes of KVM switches that are reviewed, are based on different types of core technologies in terms of how the KVM switch handles USB I/O devices—including keyboards, mice, touchscreen displays, etc. ...

Breakout Cable
Breakout-style fiberoptic cable (also called breakout cable or fanout cable), is an optical fiber cable containing several jacketed simplex optical fibers packaged together inside an outer jacket. This differs from distribution-style cable, in which tight-buffered fibers are bundled together, with only the outer cable jacket of the cable protecting them. The design of breakout-style cable adds strength for ruggedized drops, however the cable is larger and more expensive than distribution-style cable. Breakout cable is suitable for short riser and plenum applications and also for use in conduits, where a very simple cable run is planned to avoid the use of any splicebox or spliced fiber pigtails. Because each fiber is individually reinforced, the cable can be easily divided into individual fiber lines. Each simplex cable within the outer jacket may be broken out and then continue as a patch cable, for example in a fiber to the desk application in an office building. This e ...
