Abstract: The Self-Sustaining Data Center makes use of a site that is inherently immune to catastrophic events and incorporates features to facilitate the substantially continuous availability of data stored therein. The architecture of the Self-Sustaining Data Center makes use of multiple data communication links to sites that are remote from the data center to enable the uninterrupted communication access of customers' computer systems to the mass storage systems operational at the Self-Sustaining Data Center. The Self-Sustaining Data Center also includes facilities that include at least one of: power generation, housing and food for data center staff, and voice communications facilities, thereby to enable the Self-Sustaining Data Center to continue its operation for an extended period of time in the absence of municipal utility services and the possible inability of the data center staff to access outside sources of food and water.
