With the increasing need for computing power and a growing premium on floor space, server rack is often used to achieve high density in the data center. The proper use of network racks can facilitate a consolidation of different network equipment in an organized, safe and efficient manner. There are many types of server racks to choose from, but which one is the most suitable for your data center?
Open frame rack consists of mounting rails without sides or doors – an open-air structure for mounting network equipment. They’re typically used for server room that don’t require physical security and don’t need added airflow control. An open frame rack cabinet provides easy access and offers plenty of open space for cable management, making this solution ideal for network wiring closets and distribution frame applications with high-density cabling. There are two basic types of racks: 2-post and 4-post rack. 2-post racks generally require less depth but support less weight than 4-post racks.
Cabinet has front / rear doors, side panels and four adjustable vertical mounting rails (posts). It generally refers to “enclosed rack”. Since the doors and side panels can be locked, enclosed racks provide physical equipment security at the rack level. Despite the benefits of network cabinets, they also pose some challenges – particularly in the area of cooling. A server rack cabinet, obviously, has much less access to outside air. So it will require some kind of venting for air cooling.
Wall mount rack is designed to be attached to the wall, in order to save floor space and fit in areas where other racks can’t. It is generally in open frame or cabinet style, and mainly used for housing network equipment like fiber patch panels and switches. But it also has some cons: it is smaller than other rack cabinets, so can’t support much weight and does not offer the same amount of security that a full enclosed server rack could offer. If you run a small/home-based offices or larger offices that are looking to add an additional rack to an existing system, wall mount racks are an affordable option.
A properly chosen server rack should fit the dimensions of the equipment. Although 19-inch racks are always the same nominal width, the height and depth vary. A commonly used measure of the height of a rack is the so-called rack unit (U), which is defined as 1.75 inches. The width and depth of the rack is typically measured in standard units. The most popular standard data center racks have a width of 19 inches and a height of 42U (73.5 inches high).
For a flexible and ease-to-manage cabling environment, enough usable space should be left in the rack cabinet after the devices being installed. In addition, some server rack even has wheels in case the racks should be moved.
With more and more devices are added to the data center, the network racks should have enough weight capacity. The number of switches, cables, PDU and overhead cable mounts should all be considered during the selection of a rack. Selecting a strong rack is necessary.
The cooling cost of data center is keeping increasing nowadays. Proper server racks contribute to the cooling efficiency. Racks with airflow management accessories could be a good choice. Some other accessories like the door of the racks can also affect the cooling efficiency. Most of the rack door provide at least 64 percent perforation for proper air flow.
Some devices in data centers might need security protection. Thus, doors, side panels and roof can be installed on the server racks. The designs of these accessories also come in various types according to applications.
Server rack can hold all standard 19-inch rack-mountable equipment, as long as it isn’t too deep for the rack cabinet or too high to fit in the available rack spaces. The equipment often includes removable mounting brackets that fasten to the vertical rack rails with screws. Heavier equipment may also include horizontal rails or rack shelves that mount in the rack to provide extra support. Other rack accessories that support the operation of the production equipment includes UPS systems, PDUs, cable managers, switches, patch panels and fiber enclosures.
