Penn Web Server Technical Information
The www.upenn.edu service is running on a pair of fully redundant servers hosted in two data centers, approximately five blocks apart, and each houses a fully mirrored storage array. Data centers are served by separate power grids and include fully redundant power and HVAC systems. Data is replicated in real time between the two locations. The configuration is designed to survive the failure of any component, including the loss of an entire data center, power grid, local network or Internet connection.
