LG Electronics' 2.5 MW CDU Earns Nvidia 'DSX Ready' Approval
IT DAILY · · 1 views
✦ AI Summary
LG Electronics announced on the 22nd that its 2.5 MW cooling distribution unit (CDU) has received Nvidia AI factory specification approval, the 'DSX Ready CDU.'
The product met the large-capacity CDU requirements among the specifications for building an Nvidia AI factory, and DSX Ready targets large-capacity products of 2.3 MW or more.
LG Electronics has now received Nvidia specification approval for its 2.5 MW CDU, following approvals for 600 kW in July and 1 MW in September.
LG Electronics announced on the 22nd that its 2.5 MW cooling distribution unit (CDU) has received Nvidia AI factory specification approval. The approval designation is Nvidia's "DSX Ready CDU."
The product meets the large-capacity CDU requirements among the specifications for building an Nvidia AI factory. Nvidia has the "DSX AI Factory Platform," which covers computing, networking, power, cooling, facilities and software, and grants DSX Ready approval to products that meet the relevant requirements.
The DSX Ready target in the CDU category is large-capacity products of 2.3 MW or more. LG Electronics' liquid cooling solution CDU lineup consists of 600 kW, 1 MW and 2.5 MW models.
The approved product is intended to address demand for large-capacity liquid cooling as AI servers become more highly integrated. The approval comes as demand for liquid cooling grows alongside the increasing density of AI servers.
Following LG Electronics' earlier approval in July for its 600 kW CDU and its September approval for its 1 MW CDU, the company has now also received Nvidia specification approval for its 2.5 MW CDU.
A CDU is a liquid cooling facility that reduces server heat through cooling water circulation. As AI accelerator power consumption rises and server density increases, making it harder to handle heat with air cooling alone, the importance of liquid cooling is growing.
The use of large-capacity CDUs is expanding as servers become more densely integrated. The mainstream approach used to be In-Rack, which installs a small CDU for each individual server rack, but recently the In-Row method, in which multiple racks are grouped by Row and cooled with a single large-capacity CDU, has been spreading.
The capacity of the latest AI server racks is about 120 kW. If 20 server racks make up one cooling group, the required capacity is about 2.4 to 2.5 MW, and this 2.5 MW CDU is aimed at highly integrated AI server environments.
The share of liquid cooling adoption in AI data centers is expected to rise sharply. TrendForce projected that the adoption rate of liquid cooling solutions in AI data centers will expand from 14% in 2024 to about 60% in 2027.
LG Electronics is seeking to expand supply to AI data center customers. LG Electronics offers 600 kW, 1 MW and 2.5 MW CDUs, along with chillers, computer room air handlers (CRAHs) and cold plates for direct cooling of AI chips, and also has a Chip to Chiller product lineup. Based on this Chip to Chiller lineup, LG Electronics plans to expand supply to AI data center operators.
Lee Jae-seong, head of LG Electronics' ES Business Division, said the company plans to begin supplying cooling solutions with high reliability and efficiency to global big tech companies in earnest, following Nvidia DSX specification approval.
