Microsoft’s launched Generation 4 Modular Data Center design at the PDC 09 - The 20-foot container built on container-based model.

Microsoft says the use of server-packed containers – known as Pre-Assembled Components (PACs) – will allow it to slash the cost of building its new data centers.

Completely optimized for outdoor use, with a design that relies upon fresh air (”free cooling”) rather than air conditioning. Its exterior is designed to draw fresh air into the cold aisle and expel hot air from the rear of the hot aisle.
