LOOKING AT TECHNOLOGY TRENDS MOVING FORWARD , CONSTANTLY INCREASING FAN POWER ON A RACK WILL NOT BE A LONG-TERM SUSTAINABLE SOLUTION .
UNCOVERING THE LAYERS
• The variance in temperature of all HDDs was just 3 ° C , regardless of location inside the JBODs
• HDD systems could operate reliably in rack water inlet temperatures up to 40 ° C
• System-level cooling power was less than 5 % of the total power consumption
• Mitigating acoustic vibrational issues
While consistency is a key benefit , cooling all disks at a higher water temperature is important too . This means data centre operators do not need to provide chilled water to the unit . Reduced resource consumption – electrical , water , space , audible noise , etc . – all lead to a greater reduction in TCO and improved ESG compliance . Both of which are key benefits for today ’ s data centre operators .
As demand for data storage continues to escalate , so will the solutions needed by hyperscale data centre providers to efficiently cool the equipment . Liquid cooling for high-density storage is proving to be a viable alternative as it cools the drives at a more consistent temperature and removes vibration from fans with lower overall end-end power consumption and improved ESG compliance . At a time when data centre operators are under increasing pressure to reduce energy consumption and improve sustainability metrics , this technology may not only be good for the planet but also good for business .
Enabling innovation in storage systems
Today ’ s HDDs are designed with forced air cooling in mind , so it stands to reason that air cooling will continue to play a role in the short term . For storage manufacturers to embrace new alternatives demonstrations of liquid cooling technology , like the one Meta conducted , are key to ensuring adoption . Looking at technology trends moving forward , constantly increasing fan power on a rack will not be a long-term sustainable solution .
Data halls are not getting any larger and costs to cool a rack are increasing . The need for more data storage capacity at greater density is exponentially growing . Storage designed for Precision Liquid Cooling will be smaller , use fewer precious materials and components ,

perform faster and fail less often . The ability to deliver a more cost-effective HDD storage solution in the same cubic footprint delivers not only a TCO benefit but contributes to greater ESG value as well . Making today ' s technology more efficient and removing limiting factors for new and game-changing data storage methods can help us meet the global challenges we face and is a step forward towards enabling a better future . �
