Racks of servers and GPU/accelerator nodes - the actual compute that AI and cloud workloads run on.
The compute layer - racks of servers and GPU/accelerator nodes that run the AI and cloud workloads a data centre exists to serve.
This is where the economic value of a data centre is realised - everything else (power, cooling, building) exists to keep this layer running.
Hardware distributors and system integrators capture margin on every refresh cycle; the chips themselves are mostly imported, so India's exposure is concentrated in distribution, assembly and HPC/AI server integration rather than silicon.
