A recent Beige Market Intelligence report entitled ‘Global Data Centre Cooling Market – Strategic Assessment and Forecast 2017-2022’ is projecting that the global data centre row-cooling market will quadruple in sales volume by 2022.
The report defines the various data-centre cooling options as:
· Room-level: CRAC/CRAH cooling systems that help maintain uniform temperature inside the data centre and avoid hot spots;
· Row-Level: the CRAC units are used to supply air into the cabinets arranged in a row; and
· Rack-Level: The CRAC units attached to the racks.
The report further notes that data-centre design and architecture consulting service providers across the globe are widely divided on the issue of cooling architecture. Some of them are preferring rack cooling as a long-term alternate to room cooling. However, others are rejecting it because rack cooling is still in nascent stage of evolution, requiring another 3-4 years to grow up to be a complete alternate to room solutions.
Hence, some of the data-centre design and architecture providers are preferring row cooling over rack cooling. Because, it is an emerging technology and can reduce the OPEX, as well as carbon emission by almost 50% for a Tier-4 data centre.
The report adds that room-level cooling accounts for almost 77% market share. However, the demand for room-level cooling is falling, although it won’t be write-off so quickly. Its demand on large Tier-4 data centres having real-time applications or high-computing devices has reduced. In those cases, the demand for rack-level cooling and row-level cooling is increasing. On a large data centre, row cooling can enter as an alternative to room-level cooling.
The data-centre row-level cooling is projected to increase almost fourfold by 2022. Data-centre operators are designing containment systems, housing IT equipment in data centres with small cooling units which offer row-based cooling at the heat source. The need for high-density servers triggers a concomitant increase in adoption of row-cooling solutions. Constant innovations in the data-centre cooling space are expected to boost the revenue generated by row cooling solutions in the market.
Almost 50% of new data-centre construction projects in the US in 2016 and 2017 are preferring row-cooling over room-cooling. Hence, in US, the market is expected to grow by almost 22%. In Asia Pacific, the growth is expected to be seen post-2018 because, by 2018, anticipating 45-50% of new data-centre constructions to opt for row cooling over room cooling.
