A blade server, sometimes referred to as a high-density server, is a compact device containing a computer used to manage and distribute data in a collection of computers and systems, called a network. Its role is to act as a conduit between computers, programs, applications and systems. In general, a blade server consists of a chassis, or box-like structure, housing multiple thin, modular electronic circuit boards, known as server blades. They are called blades because of their ultra-thin shape. Each blade contains a single server, often dedicated to a single application. The information within blade servers is stored on a memory card or other memory device. In addition, the individual blades contain processors, memory, integrated network controllers, an optional Fibre Channel host bus adaptor (HBA) and other input/output (IO) ports. These are used to connect server blades to other server blade units within the system, or to connect individual blades to power sources. Benefits of blade serversBecause most blade servers are dedicated, meaning they are focused on a single use application, professionals have more control over how they are accessed and used, and how data is transferred between devices. Some of the benefits of blade servers compared to their traditional predecessors include:
Uses of blade serversTo maximize their efficiency, blade servers are often dedicated to single-task functionality. Some example of tasks a server may perform include:
Difference between blade servers and rack-mounted serversBlade servers and rack servers are two common features of data centers and while very similar, they have some significant differences. Typically, rack servers, also known as rack-mounted servers, are created to fit vertically within a shelf-like structure called a rack, typically housed in a data center or server room. They are ideal for projects with low CPU requirements or small amounts of physical space. The number of servers stacked within a rack-mounted system is completely variable based on the size and extent of an organization's project needs. Rack servers are fully equipped to work as a stand-alone computer and are able to run multiple, complex applications and processes, using powerful memory and CPU resources. Their modularity and configurability make them convenient to assemble and store. Without the need for a large chassis to hold the servers, the rack-mounted servers are ideal for projects that require a small number of servers between, for instance, two and ten. Blade server technology is very similar to rack-mounted server technology. Blade servers, much like rack-mounted servers, are usually stored in a vertical stack in a data center or server room, though they tend to appear in much larger data centers for projects with higher power needs. One key difference is that the individual servers are highly stripped-down, with simple, sometimes singular functionality. This allows for multiple small, flat, horizontal blades containing individual servers to be stored within a chassis and stacked vertically. Unlike rack servers, blade servers generally do not function as stand-alone servers--they work best when placed with others in a chassis and combined into a blade service stack. Another major difference is that each individual server is typically dedicated only to a single application, as it generally only contains CPUs, controllers and memory. Blade server systems are much easier to fix than larger rack-mounted servers because the modular parts can be repaired individually without disrupting the larger system--in other words they can be hot-swapped. Companies need to be proactive researching the company that makes the blade server model they purchase for the organization. When a company chooses a specific model of blade servers, they need to prepare for the possibilities of vendor lock-in, so switching between products is costly as it involves a complete overhaul of all the available equipment. Blade servers also require fewer wires and cables than typical stack-mounted servers, and are powerful processors compared to the space they occupy.
History of blade serversThe first servers were offered in the 1990s and soon after there was a need for dedicated servers, especially in industries with privacy and data safety requirements, such as healthcare. Over time they became more widely used in other industries, especially as security threats and viruses continued to evolve. The need for smaller, more compact and faster servers increased with each new company and technology. Blade servers were invented in the 2000s by Christopher Hipp and David Kirkeby at their company, RLX Technologies in Houston. Both Christopher Hipp and David Kirkeby were former employees of Compaq, one of the early companies to sell computers and computer products. Hipp was an entrepreneur and inventor who was especially interested in the advancements of graphic design as technology improved. Kirkeby was his co-worker who helped to invent the patent for the blade server. They created the first commercial blade server in 2001 to meet an industry need for more compact and efficient data storage technology. Eventually the
blade server design was acquired and manufactured by Hewlett Packard and other companies. Types of blade serversBlade servers are categorized by type based on various traits, such as differing CPUs, amount of RAM and cache memory or connections. Blade servers can be equipped with different central processing units such as Intel, Advanced Micro Devices (AMD), Motorola and Sun Microsystems. The CPU does the processing and computing for the entire system, and the more powerful the central processing unit, the more functionality the computer system is able to perform at a given time. A blade server can also contain a wide variety of memory systems. The first is static RAM (SRAM), one of the earlier forms of storing information common in digital cameras and printers that stores data exactly as it is. Another is dynamic RAM (DRAM), a form of storage that updates as it works and is common in more complex systems like video game consoles. Lastly is double data rate synchronous dynamic random access memory (DDR SDRAM), most commonly used in servers and computers with a great deal of visual content. RAM is used to manage and store information and complete processing and calculations in real time. While blade servers have a modular and uniform design that makes them easy to move between data centers, they can have a variety of outer connectors. For example, they may be equipped with an Ethernet output, a token ring, a fiber channel which can be up to 6 miles long or a fieldbus network protocol. Additionally, blade servers may be connected to different storage connection methods, including the following:

Future of blade serversWhile blade servers are a highly common aspect of many business server rooms, there are other technologies that may replace their commonality. Brick servers, which unlike a blade server do not require a chassis outer container, have many of the benefits of compactness and compatibility, while taking up even less space. Similarly, cartridge servers are small like printer cartridges and commonly used in various industries. In addition, modular hybrid servers address some issues with hard-wired connections, temperature management and ease of movement within a server system. As power consumption and thermal design power (TDP) increase with ever-improving technologies, the demand for servers that can be stored seamlessly and easily cooled continues to grow.

Is a mainframe a network of several servers together in a single location?Answer: A mainframe is a network of several servers together in a single location. A supercomputer is the fastest, most powerful computer--and the most expensive. Most computers and electronic devices are analog, which uses only two discrete states: on and off.
Which of the following server types is housed in a slot on a metal frame group of answer choices?30 Cards in this Set. Which of the following are the two main components on the motherboard?While motherboards have many components, the two main items are the random access memory (RAM) and the central processing unit (CPU).
What is a frame that houses the system unit on a desktop called?A chassis (pronounced TCHA-see or CHA-see ) is the physical frame or structure of an automobile, an airplane, a desktop computer, or other multi-component device.
