AI data center components explained: GPUs, HBM, cooling, and power
In an AI data center, GPUs perform computations and high-bandwidth memory (HBM) feeds them data. Cooling removes heat, while an uninterruptible power supply (UPS) keeps equipment powered during short interruptions.
How do GPUs and HBM work together?
A GPU can perform many calculations in parallel. HBM stacks memory dies and uses a wide interface to transfer data. Even a fast processor can sit idle when its data arrives too slowly.
Why do power and cooling matter?
Servers generate heat as they consume electricity. The cooling system carries that heat away. Transformers convert voltage, and a UPS bridges a short outage while backup power becomes available.
What do network switches and server racks do?
A switch directs data between servers. A rack is the frame that mounts equipment such as servers and switches. Both belong to the same facility, but they solve different problems.
