It's a data centre being build specifically to run LLMs (and possibly other ML models). As such, it will be focused on NVIDIA servers with large numbers of inter-connected GPUs (so they can run the 2T-4T parameter models from OpenAI, Anthropic, etc.) [1].
It's a different build-out to a data centre that can host video/YouTube content (fast CPU, no GPU, large number/size of hard drives), or that can run web servers (fast CPUs, low to average hard drive capacity).
