What is a High Density-Data Centre?

We use the measurement ‘Kilowatts’ to measure the density per cabinet and since mid-2016 a Data Centre that uses more than 10 kW per cabinet is known as a high-density Data Centre. Another way of measuring Data Centre Density is by measuring how much energy is consumed per square of the floor space. Typically, a high-density Data Centre is one using more than 150 kW per square foot.

Advantages

Data Centres that use higher amounts of power in a compact in-house setup can offer your business and customers a better deal. If a Data Centre can pack more power efficiently into the same space, then they can have more clients in the same space - this helps with the Data Centre's cost for buying or renting more space. 

The efficiency of a high-density setup also helps lower overall costs. The more compact the setup is the easier the Data Centre is to manage. This saves the Data Centre both time and money which will result in your business saving money also. Even though a high-density rack will consume more power and will need possibly more cooling that a lower density rack, you will need fewer racks. This will also save on costs and maintenance. 

A high-density Data Centre is the current and future of Data Centres in many ways. The amount of data everyone uses today is vastly more than it was a decade ago - and this increase in data will only continue. For any company to be able to keep up with storing this amount of data also being able to offer storage in some cases, they will need to use a Data Centre with high density capabilities. This also means that Data Centres need to make sure they need to upgrade to high density racks if they haven't already.

Disadvantages

Having a high-density setup not only means more power – it also means that the cabinets are also going to be heavier.  One of the disadvantages of this is the difficulty of moving cabinets as they are considerably heavier. Another disadvantages of upgrading to a high-density setup is having to build a new rack setup that can support the cabinets weight. A lower density rack can weigh around 2,000 lbs and with a high-density rack they can weigh around 3,500 lbs.

Lastly, another factor to consider is the added cost of extra power supply and cooling.  One of the ways experts deal with cooling is by spreading out the load of the cabinets to underpopulated areas of the racks. This solution is not the most efficient because it takes more room within the Data Centre, which means they are not taking advantage of the space saving capabilities of a high-density setup.

The Future of Data Centres

There are many different views on the future of high-density Data Centres. One of the main reasons for this is the never-ending advancements in technology – the definition of what a high-density Data Centre changes each year.  As of 2018, 10 kW is becoming the new standard for many Data Centres – some hyper-scale facilities are even installing 15 / 25 kW racks. The way that the technology is always advancing means that the Data Centres need to keep up with the advancements.

What may be considered a high-density Data Centre today will most probably not be considered still high-density in 2030. Can Data Centres keep up with these changes without rebuilding the Data Centre? High-density Data Centres also require an increased amount of power per cabinet, but it also means an increased amount of cooling also. This can be a future challenge for Data Centres that already have built in cooling systems.

There are man benefits of having a high-density Data Centre for your business. Despite the disadvantages, it seems very clear that high-density installations are here to stay and will still be implemented for the foreseeable future. When looking for a Data Centre we recommend asking a industry expert!
