What is colocation?
“If you’ve perhaps 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 bit that is little secure storage, but instead than looking after the kind of stuff you would find in your loft, we’re looking after others’ servers.
Put another way, companies actually move their servers from their in-house comms room into a metal cage, otherwise understood as a rack, in a building that is created specifically to check after their IT equipment, otherwise called a data centre.”
Exactly how much would this actually cost?
“There are three major factors that are determining the cost of colocation uk. The first is the type of data centre IT equipment will be drawing 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.
So let’s start because of the data centre itself. Broadly speaking, you can find likely to be three factors that determine whether or perhaps not the base cost of the rack is during the budget or premium level. So the factor that is first location. Data centres located in major metropolitan areas or capital cities are typically somewhere between 30-40% more expensive compared to those found in non-metro areas. Demonstrably data centres based in the countryside in the middle of nowhere, they’re probably going to be in the cheaper end associated with the scale, whereas information centers on the periphery of major cities will be approximately the 2
The second factor is tier levels and redundancy. So data centres that have got high level of redundancy are typically rated during the tier four level, whereas information centres with low level of redundancy are rated as a tier one or tier two level. When once more, 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 factor that is third technical support and SLAs. Data centres that do offer SLAs on things like power and connectivity will typically cost more. And on the technical support side of things, there are some data centres which will be in a position to give you access to the facility 24/7, whereas other data centres, possibly on the cheaper end of the scale, will only manage to offer you access and technical help Monday right through to Friday during normal working hours.”
Requirement for your IT equipment
“So having picked your data centre, the next major determining factor in the cost of uk colocation 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 server that is rack-mounted.
Typically, data centres will offer racks in three sizes that are major 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. With custom sizes, but they will typically cost more because they will take up more space on the data floor if you want, data centres can provide you.
So the third major determining cost is power. Servers run 24/7 and of course use a huge amount of electricity. In the days of the past, for each and every kilowatt of power you put in a server, you had to spend almost a kilowatt of capacity to cool it down using air conditioning units. Nowadays, in modern data centres like this, you can use far more efficient cooling systems like evaporative cooling, which use up far less electricity to cool off one kilowatt of power you put into a server.
And so the amount of power that you can place into a rack is going to be dependent on its size and also the charged 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 energy density and needs specialist equipment not only to bring the charged power to the rack, but also to cool the servers down.”
