An Expert's News & Views - Cooling your Servers

Here at Maxi-Cool we are primarily interested in server cooling solutions, prompted by the cooling problems of our clients. Every server rack site is different and the cooling requirements vary depending on the performance of the servers themselves. We specialise in providing solutions for challenging server rack locations and can meet very specific server cooling requirements. If you have an unusual server rack situation and your current cooling options are causing problems, contact us for a chat.

The Summer is Coming - What does this mean for your server rack cooling?

22 May 2019

Summer is just around the corner it seems, and the weather is starting to show it. Server cabinet cooling can be under extra strain when the average temperature rises, so it’s crucial to have an effective server cooling system in your server cabinet primarily so the servers don’t run slowly or even crash. An increase in the outside air temperature also increases the possibility of ‘hotspots’, places within the server cabinets in which air does not flow evenly, leaving some parts entirely uncooled. Inadequately cooled server racks, especially as the weather gets warmer can lead to vastly reduced business productivity.

A rise in the temperature outside causes the temperature inside buildings to rise and therefore any cooling effect of the ambient air temperature on server racks is reduced in relation to the extent to which the outside temperature rises. The fact that adequate server rack cooling is essential for the smooth running of businesses is indicated by the scale of the cooling solutions and the allocation of large budgets to server cooling solutions. Facebook for example, a company where data management is mission critical and with large budget has its servers in Lulea in northern Sweden (just 70 miles south of the Arctic Circle). The scale of this server cooling solution is vast and the location, which takes advantage of the naturally cold air temperature near the Arctic Circle supports the mechanical cooling of the datacenters.

Most business, especially SMEs, do not have the luxury or the budget for server cooling on the scale of Facebook, however data is mission critical to all businesses these days, in one form or another. Whether data is stored in house, or stored on the cloud and supported in house through a local ‘edge’ support server, or there is processing, either volume transactions or huge files unsuitable for the cloud transmission, local servers require local cooling solutions. This can have another dimension depending on the building that businesses are in, be it historical restrictions, landlord restrictions, or just small. All servers need adequate cooling to function properly and especially so as the weather gets warmer. Most businesses rely on air conditioning to cool the room that the servers are in and when the weather gets warmer crank up the air conditioning and support this by simply opening the windows, doors and sky lights to provide as much cool air as possible. Often this isn’t enough to keep everything working properly, especially when there are people working in and amongst the IT equipment.

MAXI-COOL was developed to create a compact server rack cooling system that would provide significant cooling (4kW and 5kW) and be a system that would comfortably work in any office environment. With Maxi-Cool, an increase in the outside air temperature has a negligible effect on the functioning of servers and our system works independently of any existing air conditioning systems in the building. Rising temperatures require enterprising and bold solutions to server cooling problems, and in MAXI-COOL there is a patented server cooling system that can provide rack cabinets with effective and efficient cooling.

If your office is getting very hot and your servers are running slowly – give us a call for another approach to server rack cooling solutions!
