A logic analyzer is an electronic instrument that captures and displays multiple logic signals from a digital system or digital circuit. A logic analyzer may convert the captured data into timing diagrams, protocol decodes, state machine traces, opcodes, or may correlate opcodes with source-level software. Logic analyzers have advanced triggering capabilities, and are useful when a user needs to see the timing relationships between many signals in a digital system.
A colocation centre or "carrier hotel", is a type of data centre where equipment, space, and bandwidth are available for rental to retail customers. Colocation facilities provide space, power, cooling, and physical security for the server, storage, and networking equipment of other firms and also connect them to a variety of telecommunications and network service providers with a minimum of cost and complexity.
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is fitted inside the lower lid enclosure under the keyboard, although many modern laptops have a built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems, laptops tend to run on desktop operating systems, which were originally developed for desktop computers.
A data center is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems.
A modular building is a prefabricated building that consists of repeated sections called modules. Modularity involves constructing sections away from the building site, then delivering them to the intended site. Installation of the prefabricated sections is completed on site. Prefabricated sections are sometimes placed using a crane. The modules can be placed side-by-side, end-to-end, or stacked, allowing for a variety of configurations and styles. After placement, the modules are joined together using inter-module connections, also known as inter-connections. The inter-connections tie the individual modules together to form the overall building structure.
A blade server is a stripped-down server computer with a modular design optimized to minimize the use of physical space and energy. Blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. Unlike a rack-mount server, a blade server fits inside a blade enclosure, which can hold multiple blade servers, providing services such as power, cooling, networking, various interconnects and management. Together, blades and the blade enclosure form a blade system, which may itself be rack-mounted. Different blade providers have differing principles regarding what to include in the blade itself, and in the blade system as a whole.
Prefabricated homes, often referred to as prefab homes or simply prefabs, are specialist dwelling types of prefabricated building, which are manufactured off-site in advance, usually in standard sections that can be easily shipped and assembled. Some current prefab home designs include architectural details inspired by postmodernism or futurist architecture.
Shipping container architecture is a form of architecture that uses steel intermodal containers as the main structural element. It is also referred to as cargotecture or arkitainer, portmanteau words formed from "cargo" and "architecture". This form of architecture is often associated with the tiny-house movement as well as the sustainable living movement.
A portable, demountable or transportable building is a building designed and built to be movable rather than permanently located.
A prefabricated building, informally a prefab, is a building that is manufactured and constructed using prefabrication. It consists of factory-made components or units that are transported and assembled on-site to form the complete building. Various materials were combined to create a part of the installation process.
Sun Modular Datacenter is a portable data center built into a standard 20-foot intermodal container manufactured and marketed by Sun Microsystems. An external chiller and power were required for the operation of a Sun MD. A data center of up to 280 servers could be rapidly deployed by shipping the container in a regular way to locations that might not be suitable for a building or another structure, and connecting it to the required infrastructure. Sun stated that the system could be made operational for 1% of the cost of building a traditional data center.
A field kitchen is a kitchen used primarily by militaries to provide hot food to troops near the front line or in temporary encampments. Designed to be easily and quickly moved, they are usually mobile kitchens or mobile canteens, though static and tent-based field kitchens exist and are widely used.
The Cisco Nexus series switches are modular and fixed port network switches designed for the data center. Cisco Systems introduced the Nexus Series of switches on January 28, 2008. The first chassis in the Nexus 7000 family is a 10-slot chassis with two supervisor engine slots and eight I/O module slots at the front, as well as five crossbar switch fabric modules at the rear. Beside the Nexus 7000 there are also other models in the Nexus range.
A point of delivery, or PoD, is "a module of network, compute, storage, and application components that work together to deliver networking services. The PoD is a repeatable design pattern, and its components maximize the modularity, scalability, and manageability of data centers."
Power usage effectiveness (PUE) or power unit efficiency is a ratio that describes how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment.
A Portable Modular Data Center (PMDC) is a type of modular data center designed for portability. PMDCs are typically built into 20, 40, or 53-foot intermodal containers. Designed to be weather-resistant and well insulated, PMDCs can be placed in many environments. They can be stored and then deployed when needed to augment traditional data centers or provide backup functionality in the event of a disaster.
The HP Performance Optimized Datacenter (POD) is a range of three modular data centers manufactured by HP.
HP Flexible Data Center, also termed FlexDC, is a modular data center built from prefabricated components by Hewlett-Packard and introduced in 2010. It is housed in five large buildings that form the shape of a butterfly. The Flexible DC looks like a traditional building, but it is fabricated off-site in order to circumvent the two years it often takes for traditional building construction. The building consists of a central admin area, surrounded by 1-4 data halls. FDC offers cooling options that are optimal for each type of climate.
Immersion cooling is an IT cooling practice by which servers are completely or partially immersed in a dielectric fluid that has significantly higher thermal conductivity than air. Heat is removed from the system by putting the coolant in direct contact with hot components, and circulating the heated liquid through heat exchangers. This practice is highly effective as liquid coolants can absorb more heat from the system than air. Immersion cooling has many benefits, including but not limited to: sustainability, performance, reliability, and cost.
A green data center, or sustainable data center, is a service facility which utilizes energy-efficient technologies. They do not contain obsolete systems, and take advantage of newer, more efficient technologies.
