Local impact and modularity : The discussion begins by highlighting the importance of considering local factors when designing data centres . Factors such as load shedding , power usage , and temperature variations across different markets and regions need to be taken into account . The panel emphasises the need for data centre designs to be adaptable and modular , enabling them to be deployed worldwide . By adopting modular solutions and considering commonality within each market , data centre operators can achieve consistency and efficiency across various locations . The panel discusses the benefits of modular solutions , which allow for flexible expansion and efficient use of resources . Modular data centres can be easily integrated into existing infrastructure , supporting scalability and adaptability to changing demands .
Efficiency in system design and management : The panel emphasises the need for efficient system design that goes beyond considering worst-case scenarios . Instead , the focus is on developing systems that can adapt and perform optimally during regular operations . The discussion explores the concept of managing systems efficiently by switching on and off cooling elements based on real-time requirements . The use of variable speed compressors and fans is highlighted as a way to enhance cooling efficiency , especially for large machine units . By optimising cooling distribution and considering customer needs , data centre operators can achieve greater flexibility and energy efficiency .
Addressing rattling issues and scalability : Another crucial aspect discussed is the increasing challenges posed by rattling in data centre environments . The panel acknowledges the rise in rattling incidents and emphasises the need to design data centres that can handle higher heat loads per rack , ranging from six to eight kilowatts and even up to 20 to 24 kilowatts in certain instances . Data centre operators need to devise consistent solutions that can effectively handle higher heat loads while considering future scalability . Exploring alternative cooling methods , such as immersion cooling , is also mentioned as a consideration for future infrastructure planning .
Future-proofing infrastructure : The panel emphasises the importance of building data centre infrastructure with an eye toward the future . While air cooling remains prevalent , the discussion suggests the potential for alternative cooling solutions , such as immersion cooling . Data centre operators are advised to consider long-term infrastructure planning , keeping in mind emerging technologies and trends that may require different cooling approaches . By implementing infrastructure that is adaptable and forward-looking , data centres can remain efficient and relevant in the face of evolving demands .
By addressing local impact , adopting modular solutions , optimising system design , and planning for future scalability , data centre operators can navigate the challenges of cooling and achieve greater efficiency in their operations .
