HPC Cooling Solutions
This weeks opinion piece is on the subject of HPC cooling. The need to power higher and higher densities has kicked off an arms race between hardware vendors and cooling vendors and at the moment the hardware vendors are winning. How high will the densities go? who knows but i think we will see 150kW + racks as standard in the not too distant future.
I'm trialing a AI audio version of the opinion piece that can be downloaded via the Google drive link below. Its a 5min listen and adds a bit more context around the subject. Please let me know in the comments or DM me on what you think? I want to make my news letters as easy and accessible as possible for my subscribers, thanks.
And finally as always we have some selected industry news of interest, latest HPC Colo Deals, Low Density Colo deals and a selection of DC's we have for sale around the globe.
OPINION
Exploring Immersion Cooling, RDHX, and Direct-to-Chip for Future-Proof Datacenters
The relentless growth of data, fuelled by AI, machine learning, and high-performance computing, is pushing traditional datacenter cooling methods to their limits. As power densities skyrocket, innovative cooling solutions like immersion cooling, Rear Door Heat Exchangers (RDHX), and direct-to-chip cooling are gaining significant traction. Let's look into the pros and cons of these cutting-edge technologies.
Immersion Cooling: Submerging for Superior Efficiency
Immersion cooling involves submerging servers in a dielectric fluid, offering exceptional heat transfer capabilities.
Pros:
Enhanced Efficiency
Higher Density
Improved Reliability
Reduced Noise
Waste heat reuse
Cons:
Higher Initial Costs
Hardware warranties
Single Tenant Occupancy
RDHX: Targeted Heat Removal
RDHX systems utilise heat exchangers mounted on the rear doors of server racks to remove heat directly from the exhaust air.
Pros:
Improved Cooling Capacity
Retrofit Friendly
Increased efficiency over standard air cooling
Cons:
Usually Requires Infrastructure Upgrades
Space Requirements
Direct-to-Chip Cooling: Precision Heat Extraction
Direct-to-chip cooling involves attaching liquid cooling loops directly to heat-generating components like CPUs and GPUs.
Pros:
Maximum Cooling Efficiency
Enables High-Performance Computing
Reduced Overall Cooling Load
Cons:
Increased Complexity
Potential for Leaks
Higher Entry Costs
In Summary:
The choice of cooling technology depends on specific datacenter requirements, including power density, budget, and infrastructure limitations.
As datacenters evolve to meet the demands of the digital age, these advanced cooling technologies will play a crucial role in ensuring sustainability and performance. It is important to carefully weigh the pros and cons of each system to ensure that the proper cooling system is selected.

Good article, what maximums of cooling are you seeing per solution at present, we keep hearing 200K is here but is it still R&D or is it in the market? i know it changes every week :D
