A server room stores interconnected computer hardware to create a network of servers for managing databases or hosting software programs. It requires organization, proper temperature and humidity, and reliable power supply. Racks increase airflow and prevent overheating, and power supply design can be complex, requiring surge protectors and backup generators.
A server room is essentially an area to store a large amount of connected computer hardware. These interconnected computers create a network of servers, providing memory and operating speeds that far exceed the capabilities of a single computer. The server can be used to manage huge databases or host specific software programs for large or multi-user computers. Server rooms are the little sisters of data center facilities and often have all the headaches that go along with them on a much smaller scale.
The most common use of a server room is to hold equipment that holds information that will be available on the internet. Every web page, music download or game available on the internet is hosted within a server. An intranet within an organization works largely on the same principle as the Internet and often requires its own server.
Setting up a server room is a lot more complicated than just putting a few computers on a table and hooking them up together. These rooms can contain hundreds of hard drives connected by thousands of feet of cable. Organization is key as are procedures to ensure the correct temperature and humidity in the room. Power is also a consideration as many servers require large amounts of electricity and must maintain reliability even during a power outage.
Typically, server room equipment is housed on 19-inch-wide (48.3-centimeter) racks in cabinets or shelves that are several units high. It is recommended that each unit be securely fastened to the rack to prevent accidental breakage. Cords should be cut long enough to allow for adjustment, but not so long that they cause tangles. Cable assemblies must be bundled and tied together. Wiring for power and connectivity is usually at the rear of the units, so mobile racks are often used to provide easy access for repairs.
Another benefit of racks in server room design is the increased airflow around the individual units. This helps keep hard drives cool and prevents water condensation. Furthermore, the racks themselves can be equipped with fans or even air conditioning individually. Frequently, large room air conditioners are also used to further prevent server equipment from malfunctioning due to overheating. Since most server rooms are unoccupied, lighting is kept to a minimum to eliminate additional ambient heat.
Power supply design for a server room can be extremely complex. At the very least, the wiring and circuit boxes would have to be reassembled to handle the increased flow of electricity without shorts or surges. You must install additional surge protectors on the cabling in individual hard drives. Backup generators are, of course, highly recommended. Also, a battery-powered device called an uninterruptible power supply (UPS) can usually deliver power so quickly that you won’t notice any downtime.
