At AMD, contingency planning philosophy for key business critical systems entails installing redundant computer equipment, including SAN or NAS storage solutions, in at least two separate buildings. This type of setup allows a mirrored approach to be utilized providing full system redundancy in separate locations. It provides the ability to recover from loss of the primary data center and cause only momentary interruption to the using community. Because of reasonable fiber optic distance limitations, however, this separation will not, in the near future, be in excess of one mile. In many situations where the user base is local, this is adequate because any regional disaster spanning an area that large will also shut down the using community of
