The Brief

"In 2012 ARM Holdings required a new one megawatt high density green Data Center at their Cambridge head-quarters. The Data Center was required to occupy the smallest footprint possible, on an existing brownfield area within the grounds."

"The build, commissioning and handover had to be complete within only three months of the approved design. The remit incorporated a Tier 3 rating requirement with the lowest possible PUE for the cooling solution. An average of 16kW capacity per rack - capable of reaching 23kW with no detrimental affect to the IT server equipment or room environment."

"Finally this system had to be monitored locally and remotely with full access and control."

The Cooling Solution

The design comprised of sixty USpace 6210 48U 600 x 1200 ColdLogik compliant cabinets placed onto a raised floor in a space of only 7.5m x 13m. Sixty ColdLogik CL20 C12 rear coolers were fitted onto the cabinets complete with negative pressure hoses and flow control valves.

Complementing the CL20 rear coolers were 3 x 500kW cooling towers (run and stand-by), which were chosen for their energy efficiency, capital cost and crucially their footprint, which took up no more than 12m x 4m - to provide the client with peace of mind throughout the Data Center the patented Leak Prevention System (LPS) was included in this space joining together the cooling towers and Data Center pipework. Key to the energy performance of this solution was the fact that no mechanical cooling was used.

Award-Winning Design

Due to the phenomenal energy savings and state of the art cooling design, this Data Center has received numerous awards in recognition of its unrivalled performance and innovation.

Client Comments

"Due to the uncompromising success of the Cambridge HQ new build Data Center, ARM commissioned a further two more 1MW Data Center new builds at their Austin, Texas Offices based on the original ColdLogik Cambridge project design, as this was the only solution which could offer both efficient cooling within such a small footprint. The ARM Texas Data Center has been awarded "Innovation in a Medium Data Center" & "Green Data Center" Awards in Datacenter Dynamics' North American Data Center 2014 Categories. "
