Method and apparatus for selecting among multiple data reconstruction techniques

摘要

Multiple storage devices are monitored to detect failure of a storage device. Upon detection of a storage device failure, a determination is made regarding whether a first data reconstruction technique is available. If a first data reconstruction technique is available, the data is reconstructed from the failed storage device using the first data reconstruction technique. If the first data construction technique is not available, the data is reconstructed from the failed storage device using a second data reconstruction technique.
