OCP Global Summit 2024: Delta Builds AI Ecosystem with Alliance and Presents Multiple High-End AI Power Solutions

Delta just participated in the OCP Global Summit 2024 from October 15 – 17 in San Jose, California, USA. Continuing the theme of “Discovering Delta’s Cloud to Edge AI” from Taiwan’s COMPUTEX in June, Delta showcased their cutting-edge integrated solutions for AI data centers and GPUs. The highlighted exhibits included the cloud-to-edge infrastructures, 33kW 19” / 21” ORV3 (Open Rack v3 standard) power shelves and power capacitance shelf, AALC and liquid-cooling systems, and networking switches for AI computing racks, as well as thermal devices, DC-DC converters and power chocks for GPU processing.

At the OCP Global Summit 2024, Delta, for the first time, cooperated with nine partners: NVIDIA, Asus, Gigabyte, Ingrasys, Pegatron, Wistron, Wiwynn, and Inventec, to build the AI Ecosystem with their company identities showcased at the Delta’s stand. In the mean time, Delta’s AI power and thermal solutions were also demonstrated at some of the partners’ booths, bringing a win-win promotion through the joint exposure.

Delta also exhibited the MGX rack, which was co-designed with NVIDIA and featured Delta’s rack layout, management switches, 19-inch 1RU 33kW power shelf and 19-inch power capacitance shelf, coolant distribution unit (CDU) and server thermal solutions for the MGX compute tray. The integrated solution showcased the close partnership between Delta and NVIDIA, as well as Delta’s leading technologies and significance for the AI industry.

Among all, Delta’s power solution that support the stable and energy-efficient AI server operation got a lot of attention. The 19-inch 1RU 33kW Power Shelf is the size-reduced version of the 21-inch 1OU 33kW ORV3 one while remaining the same power output and up to 97.5% efficiency. On the other hand, the 19-inch power capacitance shelf is capable of stabilizing voltage output to ensure power supply stability and quality. These two products fulfill the power requirements of NVIDIA’s Blackwell platform.

Delta also exhibited three other ORV3-conforming AI server power shelves: the 21-inch 1OU 33kW, 2OU 66kW, and 3OU 66kW models. The new 21-inch / 19-inch power capacitance shelves were also presented during the event. Both feature lithium-ion capacitors to mitigate AC grid reflections from peak system loads. It serves as backup power with a holdup time of 18 seconds, ensuring a stable and reliable power supply for AI, cloud computing, and data centers.

Delta also highlighted its titanium-certificated power supplies, including the 5,200W CRPS and the 3,200W MCRPS. The former supports 180-264V_AC input, 12V_DC output and 12mS hold-up time at 80% load while the latter achieves 96% efficiency at 50% load.

To meet the DC/DC power conversion requirements of AI chips, Delta showcased a portfolio of DC/DC converters with output power ranging from 200W to 2,000W and maximum efficiency up to 98.5%, including the widely used 48V to 12V DC-DC converters for AI computing equipment. In addition, it also highlighted their industry-leading Vertical Voltage Regulator, which can deliver power vertically with a shortened circuit and save approximately 5-15% of power losses in the operations of AI accelerator systems.
