The number of data centres grows rapidly along with the increasing demand for data storage and the growth observed in the professional sector of Internet. Owing to this evolution, for ecological and economical reasons, new concepts such as \u2018high density\u2019 and \u2018structured cabling\u2019 are introduced in a server room. <\/em><\/strong>

\nCombell chooses structure and flexibility<\/strong>
\n\"\"<\/a>Combell\u2019s new private room at Interxion is already entirely built according to high density principles. By using cool aisle containment, which means that warm and cold air zones are kept separate, an electrical capacity of 32 amperes per rack instead of 16 can be supplied. Concretely, this represents a method upgrade that has to be taken even further on the level of hardware choices and \u2018structured cabling\u2019 principles. The more everything is concentrated in the actual racks, the more dangerous the operations in such racks become. \u201cWe cannot afford to use cables that are a few centimetres too long, because this would create a mess in the racks\u201d, says Benjamin Jacobs, CTO at Combell. \u201cIf you would then have to move a cable or perform another operation, the risk of committing mistakes would increase. Picture the difference between a disorganized cluster of cables and a nicely rolled up cable: the risk of making knots is much higher with the disorganized lot. Combell chooses to cable all its racks in advance in as orderly a fashion as possible. We work with patch racks to establish the necessary connections between the racks.\u201d<\/p>\n

Power User Efficiency<\/strong>
\nIn order to test efficiency, the PUE (Power User Efficiency) system was implemented; it allows us to compare the state of insulation, power loss, etc. for different data centres. Consequently, we try to reach as low a value as possible. Indeed, PUE1 is the equivalent of 100% efficiency.<\/p>\n

Scalability in the Cloud<\/strong>
\n\u201cThe difficulty on the level of capacity planning for such a data centre is mainly that it isn\u2019t simple to predict a certain growth, since one can place even more servers in one same rack thanks to Cloud computing. This, however, strongly depends on the ratio of Public Cloud servers over Private Cloud servers,\u201d Jacobs explains. \u201cIt is important to always have scaling possibilities at one\u2019s disposal, since infrastructures that are too small surely represent a risk for your Cloud hosting services.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
