Fire safety
State-of-the-art fire suppression systems use gases to extinguish flames, avoiding the collateral damage of traditional water sprinklers.
Sustainable power
Advanced and sustainable cooling
Our datacenters use some of the most advanced and sustainable cooling systems to keep servers running reliably.
Reuse the heat energy
Microsoft is working to reuse heat energy from our datacenters and pipe to district heating networks to help local communities meet their climate goals.
Project Olympus
In 2016, we announced Project Olympus, and shared universal motherboard and rack designs with the open source community.
Security
Power Management Distribution Unit
The Power Management Distribution Unit (PMDU) provides remotely managed power distribution and redundancy capabilities to the server rack.
Virtual Machines
Microsoft introduced its first in-house designed cloud compute processor, Azure Cobalt 100, which enables general-purpose workloads on the Microsoft Cloud, in November 2024.
GPUs
Direct liquid cooling at rack level enables 10x rack density, supporting hundreds of thousands of GPUs per region, delivering 10x the performance of today's fastest supercomputers.
The Server Room
The server room is the heart of the Microsoft Cloud's massive computing and storage capacity. Innovative server blades, designed and built under Project Olympus, Microsoft's next-generation model for open-source cloud hardware, deliver capabilities for virtual machines, AI and machine learning, and even full platform services like Microsoft 365.
