Dan Costello and Christian Belady of Microsoft Global Foundation Services discuss the Chicago datacenter in a CNET video interview.

Microsoft opened the facility in September, and are now using Container-based deployment simply plugged in to power and water spines.  This reduces the resources required – in terms of plant and packaging – and means Microsoft can meet capacity requirements at >4000 servers per day. Dan claims 50% improvements in PUE compared to conventional co-located racked servers.
