As experts of Data Centre CDM, Black Box are able to advise you on the benefits of all the major technologies employed from infrastructure design, cabinet construction, through to advanced power profiling and remote server access.
Cooling systems are a critical aspect to consider in the early stages of Data Centre design. Utilising free air cooling within hot aisle and cold aisle containment systems provides a low TCO whilst minimising OPEX costs.
Secondary Heat (sometimes called Low Grade Heat) from the Data Centre can be used to heat offices within the building rather than just being disposed of through external exchangers, turning latent heat into sensible heat.
When designing a green field data centre, another major consideration is providing adequate power to the cabinets. With the advent of blade servers which can draw around eight times as much power as a single server, customer’s power requirements have grown exponentially. With the further use of virtualised servers which due to their increased processor load also draw more current, the requirement to provide enough power can become a challenge. Bigger MPDU are required to provide power to more cabinet PDU’s, and further still is the requirement to provide customers with redundant power to each cabinet. All this adds complexity to the power requirements.
All power in the data centre is typically provided via a UPS, so that in the event of a short power cut, there is enough time and warning for customers to shut down their servers in a an organised and controlled manner.
If the data centre wishes to carry Tier approvals then the data centre UPS may need to be backed up with the use of a DRUPS or other diesel style generator. Sensible CDM dictates that Free Cooling systems should be utilised wherever possible to provide zero cost cooling for much of the year, with the use of chillers limited to summer periods when outside ambient temperatures increase above the norm.
