Description
During Long Shutdown 3 (LS3), the LHCb experiment will undergo a major upgrade, requiring a new data centre to cope with the 32 Tb/s of data produced by the detector. Part of the data-acquisition infrastructure, mostly composed of Commercial Off-The-Shelf (COTS) Data Center hardware, must be installed close to the detector, which introduces several challenges, including limited underground space, sustainability constraints, and a rapidly evolving market where computing densities are rising and direct-liquid cooling (DLC) is becoming a new standard. The project aims to build a new 2 MW data center distributed across two floors next to the cavern where the LHCb detector is located using DLC as the primary cooling technology for CPUs, GPUs, and readout boards, combined with in-row air coolers to remove residual heat. We present the design plans, cooling strategy, and integration approach for this next-generation facility, which will support LHCb Data Acquisition during the LHC-HL era.
