What exactly is a Server Room? A typical server room houses a large portion of the equipment required to run computer network systems. Environmental controls, fire suppression systems, cable management solutions, power system redundancy, and airflow planning are examples of design characteristics. The server room is a critical element in any computer facility because it protects all other equipment by preventing damage from electrical surges and providing support for the growing number of wireless devices in today's networks.
Server rooms are divided into hardware divisions. The primary division is between servers and storage. Other divisions include networking equipment, phone systems, and air conditioning. Hardware divisions should be well-lit and have open access panels for maintenance workers to easily reach components inside the case.
Servers are electronic devices that store data online for quick access by other computers or devices. Servers usually have many small circuits called "chips" installed inside them. These chips are the "brain" of the server, deciding what tasks it will perform once powered on. Each type of server uses different types of chips. For example, a web server requires different types of chips than an email server. But they both need a chip to handle memory allocation and another to handle disk operations (write/read).
Web servers are commonly used for online stores, social media sites, and other websites that display information to users.
A server room is an air-conditioned room dedicated to the continuous running of computer servers. A data center is a dedicated structure or station for this purpose. Climate is one of the aspects that influence a server room's energy usage and environmental effect. The type of climate in a server room affects the size of the cooling system needed to keep the equipment within recommended operating temperatures.
Server rooms are usually located near power supplies and other infrastructure necessary to run their contents, such as water cooling towers for heat-generating devices such as graphics processing units (GPUs). They may also contain security equipment, such as surveillance cameras, motion sensors, and fire alarms. Server rooms are often kept at a constant temperature, but some larger facilities may have separate rooms for hot-swap components such as hard drives or tape backups.
Data centers use large numbers of servers to provide computing services to businesses and individuals. Data centers use electricity to operate their facilities and equipment, which produces carbon dioxide (CO2). Operational decisions made by data center managers can affect the energy consumption and environmental impact of data centers. For example, servers in a data center can be turned off when they are not in use to reduce electricity costs.
Data centers must be maintained and upgraded to keep up with the rapid evolution of technology. This means that there will be waste produced during these activities that needs to be disposed of properly.
A server is a computer that is linked to a network of other workstations known as "clients." Client computers use the network to request information from the server. Servers often offer greater storage, memory, and computing power than standard workstations. They are usually dedicated to only one task - storing data for other computers and serving pages when requested by clients.
The most common type of server is the web server. It provides access to files that contain information used by websites to create pages that can be viewed by visitors. Web servers communicate with browsers which display downloaded pages. Some servers, such as mail servers, provide services for applications which require constant communication with many users, such as email clients or news readers. Other servers, such as DNS (domain name service) servers, allow computers to connect to other computers or devices using text-based protocols such as HTTP (hypertext transfer protocol).
Servers have various features that enable them to better serve their clients. For example, some servers are "virtual," meaning they appear to be several different computers connected to each other. This is useful because it allows server administrators to add and remove computers without disrupting the operation of the server. Virtual servers also allow server resources to be shared across many users, reducing the amount of hardware needed. Virtual servers are commonly used by Internet businesses that want to make sure that clients do not experience performance issues while still needing to scale up quickly if their traffic increases.
Hard drives and data storage banks are kept in server rooms, while servers and printers are kept in computer rooms. Because these two rooms are so different, they require distinct cooling methods. They have a propensity to overheat, which is why a conditioning unit designed for that space is essential.
The power supply in a server room must be capable of delivering sufficient electricity to the other equipment in the room as well as to the server itself. Therefore, it needs to be able to handle high electrical loads with low voltage drops across its components. These factors mean that server power supplies tend to be large and use many heavy-duty components such as transformers and capacitors. They also need reliable cooling to keep them from overheating.
Server rooms typically have one or more air conditioners or heat pumps for heating and cooling. This is because they go through cycles of heating and cooling several times during the day. Heating in the winter and air-conditioning in the summer are both forms of thermal management. The amount of energy used by equipment in a server room can rise dramatically when not cooled properly. Excess heat can cause components to fail or damage other equipment in the room. A failed or damaged component may need to be replaced, increasing the cost of ownership. Cooling systems also consume energy, so reducing the demand on them using proper thermostats can save money.
Server rooms are usually well-lit for ease of use.
The term "server" refers to a specialized computer or piece of hardware that runs server software and delivers services to other computers or clients. A server performs several roles and is available in a variety of configurations to accommodate various applications. Khara, Kanika, and Anusha are friends who use the Internet to communicate. They each have their own laptop computer but need to connect with each other through a phone line to chat online. Their school provides them with two computer terminals, one for use by Khara and another for Anusha. You will learn about the differences among server types as you explore ways that they can be used.
Servers are generally comprised of a rackmount chassis that houses a power supply, a system board, one or more CPUs, memory, storage, a network interface, and a power supply. Out-of-band administration is supported by most server hardware through a dedicated network port. In addition, some form of remote management technology is typically required for server maintenance.
The world's first commercial computer was the ENIAC, built by the U.S. Army during World War II. It had over 18,000 parts contained in six large rooms. The term "server" wasn't used then for what we think of it today; it referred to an electrical circuit that would take information from telegraph wires and transmit it back again at a different frequency. The first actual server device was developed shortly after the war by IBM and consisted of a mainframe computer with its own power supply and storage devices. They were installed in restaurants to perform tasks such as payroll and bookkeeping.
Since then, servers have become smaller and more powerful, allowing them to be placed in many different locations with ease. Some large organizations have multiple data centers - separate facilities - with their own power supplies and climate control systems where their servers can be housed. Other organizations may have one central data center where all their servers are located. There they share power supplies and cooling systems with other equipment.
