What exactly is colocation?
“If you’ve not come it to a relative of mine across it before, the best way of describing colocation uk is how I’d probably describe. It’s a little bit like secure storage, but rather than looking after the sort of stuff you would find in your loft, we are looking after other companies’ servers.
Put another way, companies physically move their servers from their comms that are in-house into a metal cage, otherwise known as a rack, in a building that is specifically made to appear after their IT equipment, otherwise known as a data centre.”
Just how much would this actually expense?
“There are three major determining factors into the cost of colocation uk. The first is the type of data centre that you move into, the second is the size and the number of racks that you’re going to be using, and the third is the amount of power that your IT equipment will be drawn.
So let’s start with the information centre itself. Generally speaking, you can find going to be three factors that determine whether or perhaps not the base cost of one’s rack is during the premium or budget level. So the factor that is first location. Data centres located in major towns or capital cities are typically somewhere between 30-40% more expensive compared to those positioned in non-metro areas. Clearly data centers based in the countryside in the middle of nowhere, they’re probably likely to be on the cheaper end associated with the scale, whereas information centres on the periphery of major cities will probably be somewhere between the two
The factor that is second tier levels and redundancy. So data centres that have got high level of redundancy are typically rated at the tier four level, whereas information centres with low amount of redundancy are rated as a tier one or tier two degree. Once again, the typical between those two is a tier three, and they’re going to typically offer a level that is good of redundancy and security.
The third factor is technical support and SLAs. Colocation uk that do offer SLAs on things like power and connectivity will cost more typically. And regarding the technical support side of things, you will find some data centres that’ll be in a position to give you access to the facility 24/7, whereas other data centres, possibly in the cheaper end of the scale, will only be able to offer you access and technical support Monday through to Friday during normal working hours.”
Requirement for your IT equipment
“So having picked your computer data centre, the next major determining factor in the cost of colocation uk will be in the size and number of racks you need for your IT equipment. Racks are typically measured by their height and specifically by the number of U you can fit into one- a ‘U’ is short for rack unit and is around about one and three quarter inches in height, and is also about the same height you would find in a standard rack-mounted server.
Typically, data centres will offer racks in three major sizes- quarter racks, which are 11U in height, half racks, which are 22U in height, and full racks, which can range from 42 to 48U in height. If you want, data centres can provide you with custom sizes, but they will typically cost more because they will take up more space on the data floor.
So that the third determining that is major is power. Servers run 24/7 and of course use a huge amount of electricity. In the days of the past, for every kilowatt of power you put into a server, you had to invest almost a kilowatt of power to cool it down air that is using units. Nowadays, in modern data centres like this, you can use far more efficient systems that are cooling evaporative cooling, which use up far less electricity to cool down one kilowatt of power you put into a server.
So the amount of power that you can put into a rack will be dependent on its size and also the power density of the data centre. A quarter rack will take anything up to around about six amps of power, in a half rack it can be around about 12 amps power, and in a full rack, anything up to 24 amps of power is considered normal power density in normal power density situations. Anything higher than this is considered higher power density and requires specialist equipment not only to bring the power to the rack, but in addition to cool the servers down.”
