Cirrascale Cloud Services deploys a variety of data center cabinet technologies across the globe. The rapid increase in power consumption by today’s AI accelerators, especially for Generative AI training and inference workloads, has pushed Cirrascale to adopt advanced cabinet cooling technologies to manage the intense heat today's servers are generating. Solutions like high-density Dynamic Density Control cabinets fand rear door heat exchangers provide targeted cooling, ensuring that even the most power-hungry AI systems can operate efficiently and reliably.
Dynamic Density Control (DDC) Technology
Dynamic Density Control (DDC) cabinet technologyis used throughout Cirrascale data centers as a complete solution in a singlecabinet that is scalable and flexible enabling Cirrascale to exceed AI, HPC,GPU and other compute-intensive demands.
These cabinets provide Cirrascale with a hybrid liquid andair cooled system that can support up to 85kW per cabinet enabling us tosupport today's latest AI accelerator deployments. Additionally, the cabinetssupport intelligent power handling, fire suppression, energy management andmore. All of the DDC cabinets are controlled by DCIM management softwarethat enables Cirrascale to receive real-time feedback on each cabinet's status.
This advanced cabinet technology enables Cirrascale to operate its partner's AI accelerators at lower overall temperature's than other comparative cloud service providers. By doing so, customers need not worry about their cloud servers throttling and experiencing a reduction in overall performance.
Rear Door Heat Exchangers
Cirrascale utilizes Rear Door Heat Exchangers (RDHx) in several of its facilities in order to offer the ability to be flexible and upgrade current data center rack infrastructure to meet the demands of today's AI accelerators. RDHx solutions offer a highly effective solution for cooling high-wattage servers by removing heat directly at the cabinet level, which minimizes the impact on the data center’s ambient temperature.
These systems work by placing a liquid-cooled panel at the back of the server rack, allowing the heat generated by high-density equipment to be absorbed and dissipated immediately as it exits the hardware. This direct cooling method not only lowers the temperature of the servers but also reduces the need for excessive air conditioning, helping Cirrascale save on overall energy costs. The RDHx system’s design enhances thermal efficiency by capturing and removing heat close to the source, making it an ideal solution for hosting high-power systems, such as those used for intensive computing applications like artificial intelligence and machine learning.
Beyond energy savings, Rear Door Heat Exchangers also offer operational flexibility and scalability. As Cirrascale grows to accommodate higher density configurations, RDHx systems can be easily integrated without requiring extensive facility modifications.
