Rack Space: DC1.AMSTERDAM makes it clear

What is rack space?

Rack space refers to space in professional racks intended to house servers, routers and other IT hardware. This is done with standardized server cabinets located in a data center. The set of services that comes with providing rack space in a shared data center is called colocation. Monitoring and (fire) protection of the servers and the other hardware in your racks are inextricably included in the colocation services. The same goes for power supply, cooling, certification and remote hands. Furthermore, connectivity such as business internet and redundantly designed network connections are also closely tied to rack space.

Rack space rental
Reliably placing and running enterprise servers and IT infrastructure by renting rack space can be done on a smaller and larger scale. Depending on the need, the business (or individual) can opt for part of a rack, an entire rack or even a series of racks in a shielded environment. The former form of rack space is known as a shared rack. The second as a full rack. A private space with server cabinets can be offered as a private cage, a private corridor or a private suite. An explanation of these different forms of rack space can be found later on this page.

Role of the colocation provider
A characteristic of purchasing rack space is that the servers and hardware you place are and remain under your own management and ownership. Whether it is one or more Rack Units (RU or U) or one or more full racks; the shared colocation provider acts purely as a facilitator. In this way, the business, organization or other owner of the IT equipment benefits from all associated, shared facilities and staff deployment, and thus shared, lower costs.

Rack space:

  • Is professional, standardized space for reliably placing and running servers and related IT hardware
  • Comes with colocation services such as climate control, security and backup power
  • Can be in the form of shared rack space, with x number of rack units as desired, or full rack space
  • In addition to the ‘shared’ variant, is also available in the form of renting multiple racks in a shielded private rack space; a private cage or private corridor
  • Is intended for placing one’s own IT infrastructure, under one’s own management and responsibility
  • Is located in a shared data center, with joint benefits of shared facilities, manpower and costs

Full rack, half rack, shared rack and rack units

Rack space for your server(s) in a data center. For large, but certainly also for small businesses, shared colocation offers flexible options. You purchase a certain number of rack units from your colocation provider, tailored exactly for the number of servers and supporting equipment you want or need to put in the data center. This can be a full rack, a half rack or simply just a few rack units. To know exactly what this means, we will now explain the different variants of rack space.

Full rack
A full rack for placing and running servers in a data center has fixed dimensions. The most commonly used variant is the 19-inch-wide full rack. The length (height) varies and is usually 42 to 47 rack units at 1.75 inches per unit. Depending on the exact type of hardware, one server or related equipment occupies one to several units. The depth of a full rack is usually 100 or 120 centimeters. Full racks are efficiently set up in cooled, secure data center locations. They also provide uniform options for redundantly connecting required power and network connections.

Half rack
Renting half a rack as rack space for your server setup usually involves renting an average of 21 rack units in one of the 19-inch server cabinets. These days, a 19-inch full rack consists of 42 to 47 units. Like with full rack space, a semi-rack is usually 100 or 120 centimeters deep and each rack unit is 1.75 inches high. Obviously, a fixed number of units per server unit, or other unit of IT hardware in accordance with worldwide standard dimensions, is also required in the half rack. For example, there is 1U networking equipment that fits in one unit, but there are also 2U servers that require two rack units. Except for the height and thus the number of rack units available, semi-racks are no different from full racks. The same goes for the centrally located data center and colocation services that ensure optimal use of the rented rack space.

Shared rack
The term shared rack (space) is closely related to shared colocation. It indicates that you can use shared rack space in a shared, commercially managed data center, including all essential, shared facilities. For the latter, consider security and safety, including physical and electronic surveillance and fire safety. With a shared rack, or shared rack space, you rent x number of Rack Units (U) to safely run the company’s servers, routers and related hardware. What exactly a (U) means, you will read in the next section.

Rack Unit (U) or (RU)
You can only rent rack space if you can also specify exactly how much of it you want. We therefore apply a specific unit for this: the Rack Unit, abbreviated U or RU.

A U (1U) has the following specifications:

1U in the world of colocation and rack space is 1.75 inches high, or 4.445 centimeters.

One such unit fits one so-called flat server (1U) or other ‘plat’ piece of 1U hardware. In addition, there are 2U and 3U servers and hardware, for example, which then logically require two and three rack units, respectively, and so on.

The width of 1 rack unit is normally 19 inches, or 48.26 centimeters. The vast majority of server cabinets have this width, and the 1U unit runs from the far left to the far right.

The depth of a rack unit is 100 centimeters or 120 centimeters; depending on the type of server cabinet that has that same overall depth. The better colocation providers today provide the latter; a depth of 120 centimeters.

How many times 1U a full rack has varies by cabinet. Full racks are designated by the height, which is usually between 42U and 47U. In other words: 42 to 47 times one rack unit.

Choosing rack space: which solutions?

A separate rack unit or a private suite. And the many possibilities in between. For every size when it comes to renting a server room, and every business need for the degree of privacy, there is a suitable rack space solution. Want to rent a half rack or shared rack? Or one or more full racks, either in a professionally secured standard server room or in a private cage? DC1.AMSTERDAM, together with our partner data centers, provides a One Stop Shop solution to any colocation demand.

Earlier in this article, we provided an explanation of server room solutions in the form of a full rack, half rack, separate rack unit or other size shared rack. We will now explain what a private cage is, as well as exactly what a private suite entails.

A private cage in a data center consists of several full server racks enclosed by a transparent fence. A range of full server cabinets are available to the company renting this private rack space. The latter can arrange and set up those racks itself, fully customized, with the servers and hardware under their own control.

A private suite in a data center consists of several full server racks that are not only enclosed, but even completely walled off. This separates that server room entirely from other data center customers, with private access for their own employees. This results in an even more luxurious image toward customers. As with the private cage, the company can completely arrange and furnish the private suite itself. Moreover, by renting a private suite, the company immediately has secured growth opportunities as well.

These are potential reasons to consider rack space and colocation services of DC1.AMSTERDAM. The reason for this may also be the desire to consolidate data center usage.
