    Hyperscalers look to disaggregate power from IT to reach 1MW racks. Google has joined Meta and Microsoft's collaboration project on a power rack the companies hope will help them reach rack densities of 1MW. AMS8 is Switch Datacenters' latest wholesale facility, located in Maasdijk, Zuid Holland, just outside Rotterdam and strategically close to Amsterdam's fiber ring. Slated for construction in 2026, this 35MW IT load campus is optimized for AI and HPC workloads, supporting 100 kW to 1 MW per cabinet. Representatives from Google, Meta, and Microsoft this week took to the stage at the 2025 OCP EMEA Summit in Dublin to discuss the previously announced Mount. At the 2025 OCP EMEA Summit today, we discussed the power delivery transformation from 48 volts direct current (VDC) to the new +/-400 VDC, which will enable IT racks to scale from 100 kilowatts up to 1 megawatt. We also shared that we'll contribute our fifth-generation cooling distribution unit. Addressing these challenges, the Open Compute Project Foundation (OCP) has introduced an ambitious redesign of data center power architecture, primarily through the implementation of innovative "1 Megawatt racks".
