Redundancy – The Key to a Quality Colocation Facility


Colocation facilities allow companies to outsource their network infrastructure by housing network equipment . If those uk colocation facilities are insufficient, your company suffers from downtime, damaged hardware, and lost business. The hallmarks of a quality colocation centre are ability and redundancy for each and every major system.

Regardless of how common colocation facilities are, there are no industry standards, regulations, or rankings available for colocation facilities. The only method to identify a good data centre or to recognize the quality of services would be to ascertain for yourself the ability and redundancy of its providers.

O Ability means that the information center can handle the present loads and reasonable load rises as the center expands.

O Redundancy is essential for functionality but hard to discover: it’s the ability of any system for a single unit to fail and then distribute that load across the remaining units without overloading.


Redundancy is calculated with the formula n+1, meaning that the system has all of the capacity it needs, plus one unit additional. For instance, if there are two UPSs from the power system, they should both be running at maximum 50 percent capacity. If one fails, another can take over without overloading. Whether there are three UPSs, then each may be at 66% capacity, and if one fails, its load could be distributed among the other two, etc.

Ideally, all programs will probably be paralyzing redundant; there are multiple units running in n+1 configuration, but no 1 unit can handle the whole building load in the event of multiple unit failures.

Redundant Power

A power outage knocks out cooling systems, fire suppression, and Internet connectivity at the Cheap Colocation Uk facility, takes down all hosted business networks, and can even damage server hardware. Assess every step of transitioning from the electricity grid to generators:

O UPSs maintain the colocation facility running while power is transferred into the generators. UPSs are computer-controlled apparatus, not just batteries, together with hardware and software failures as with other computer hardware, therefore any colocation facility must have more than 1 UPS.

O Circuit breakers or move switches automatically switch the colocation facility to generators. Switches are the most frequent point of failure through an outage and are usually manual; seem for automatically-transferring circuit breakers.

O Generators must handle the total, routine facility load. Multiple generators may indicate a chance of cascading power failures if one unit goes out because the generators are used for power instead of redundancy. One generator ought to have the ability to handle 1.5 times the regular building load.

Redundant Cooling

Servers create a lot of heat, and a colocation facility may overheat within minutes without air conditioning. Server Colocation Uk facility cooling systems not closed off, unlike routine climate controls like standard HVAC equipment. Cooling is offered via chillers which pump cooled water through specific server room cooling systems called computer room air conditioning (CRAC) units.

Like electricity systems, CRACs and chillers must maintain an n+1 configuration, but capacity of chillers and CRACs is calculated somewhat differently. To find capacity for every cooling component, take the entire tonnage divided by the square footage. The minimum advisable ability is .025 tons/foot.

Redundant Online Connectivity

Redundant service means that there are multiple Internet backbones available, in a minimum three and as many as six with Internet service routed among the different backbones for better reliability. This level of Internet connectivity makes sure that the network stays dependable, with low latency and packet loss, even when major Internet backbones return or equipment fails.

Question Everything

The only method to identify a quality colocation facility is to ask questions about every system. Although the power, cooling, and connectivity methods are distinct, the questions to ask are basically the same:

O What will be the failover procedures? Are they tested frequently?
O What’s the total load on the system?
O How many components are there? What’s the entire capacity?
O Are the programs redundant?
O Are depletable resources such as gas and batteries maintained regularly?
