In this system , we have a distribution unit , manifold unit and cooling distribution unit responsible for filling the manifold and host connections . The manifold connects to the server or chassis and is filled with a dielectric liquid to efficiently dissipate heat .
What is direct-to-chip ( D2C ) liquid cooling and why is it considered an easy-to-maintain and scalable system ? What are some challenges data centres face in the cooling process and how can they solve them ?
With direct-to-chip , there is a heat pipe or cold plate which is placed in the hottest parts of the equipment like the CPU , GPU and can also be extended to other parts like memory and power supplies . A liquid flow through this component will remove heat from the server .
Using this system in your building creates one challenge . In a standard server rack , power distribution units are placed at the rear to power individual equipment . But , in incorporating liquid cooling , a manifold is needed to distribute liquid to the equipment . This means bringing liquid into the white space , getting it even closer to the IT setup and establishing a secondary fluid network inside the white space .
When is it an ideal time to implement liquid cooling and what steps should organisations take ?
There is no perfect time to start . For organisations , you need to consider your IT demands , computing demands and future strategies . There are no limitations to this technology and it can be integrated into existing white spaces without newly built facilities . You can start by designating a corner in your white space for directorship , create a proof of concept or introduce a cube in an existing data centre based on your specific requirements .
Organisations should decide based on their kind of computing loads , even traditional ways of cooling are not bad . If you have low-density servers , sticking with traditional cooling may be reasonable due to the available infrastructure and cost-effectiveness . However , if you deal with mid or high-end loads and anticipate future changes in requirements , exploring new data centre cooling methods becomes a logical choice . So , assess your IT demand and make informed decisions accordingly .
How can organisations identify the right cooling system and what infrastructural changes do they need to make ?
It is important for every organisation to assess their IT aspect and plan appropriately from the outset . Although the technology may not be new , people may need guidance . Some experts perceive introducing liquid in whitespace as a risk , but with proper planning and the right components , this risk can be mitigated . There are existing installations that already demonstrate that this is secure , sustainable and energy efficient .
