Feeling the Flow

摘要

Data centers live and die according to their ability to cool their systems. If a data center loses its ability to keep cool, then its systems will fail. Part of the data center management team's responsibility is ensuring the systems do not get too hot. The team must also, in the event of overheating, shut down the systems. But, of course, neither shutting down systems nor letting them overheat are desirable options. One results in a temporary interruption of data flow, and the other produces a longer—possibly permanent—data flow interruption.
