A Beijing Telecommunication company was under-utilizing their rack space in their data centre. They are only able to fill about 1/2 of each rack with servers, wasting valuable data centre real estate. Installed in the rack space are high power servers which are creating hotspots in areas which area tripping the equipments alarms. Yet, when we looked at their cooling capacity, their combined cooling equipment is rate 3x over their current IT equipment load.
At this site, the industrial best practice of hot aisle/cold aisle layout was followed, however, this proofed to be insufficient as technology development quickly out-pace best practice guidelines. Since this is a productions site, many radical technologies designed for green-field, or capacity expansion was not a practical solution. In this situation, QDS helped the client recoup their valuable data centre space. We designed and implemented a cold-aisle containment solution which removed all hotspots and reduce the average inlet temperature by 3°C (see graph above).
