Abstract:
Method, system, and computer program product embodiments for throttling storage initialization for data destage in a computing storage environment are provided. An implicit throttling operation is performed by limiting a finite resource of a plurality of finite resources available to a background initialization process, the background initialization process adapted for performing the storage initialization ahead of a data destage request. If a predefined percentage of the plurality of finite resources is utilized, at least one of the plurality of finite resources is deferred to a foreground process that is triggered by the data destage request, the foreground process adapted to perform the storage initialization ahead of a data destage performed pursuant to the data destage request. An explicit throttling operation is performed by examining a snapshot of storage activity occurring outside the background initialization process.
