Compared to the colocation of dedicated servers, the only difference in service is that there is a rental of servers, you only pay for the data center space and Internet bandwidth needed for your site.
The core advantage of Colocation Server Hosting is that you can buy the server directly from the manufacturer rather than renting it from your hosting provider, which may represent a significant savings over time, and allows you to configure servers more robust.
This is service ideal for sites and usually required servers with very specific settings, running the standard offered by web hosting providers. Normally, this service is inexpensive to opt, when you require colocation of servers with multiple processors and a large amounts of memory and space for the storage.
Usually, this type of service is marketed as rental of space in the data center where the server will be installed, including rent in the supply of electric power and Internet connection.
To optimize space, data centers normally uses rack servers, whose average height is 1.75 inches (44.45 mm). A rack unit or U is a unit of measure used to describe the height of equipment. For example, one rack unit is often mentioned as “1U”, 2 rack units as “2U” and so on.
There may be some powerful servers that can occupy space more than 1U high, especially when it needs to install multiple hard drives and processors. The racks can also be used for storing other equipments such as routers, network drives, etc…
Another essential point to be consider is that in Colocation Web Hosting support is not offered by the hosting company. Thus, this service is for those, having professional IT staff and has the ability to configure servers and monitor them properly.
