Abstract
Methods and systems for transitioning write input/output (I/O) requests from a write-caching mode to a pass-through mode. The method includes determining when a condition has been met for transitioning the write I/O requests and de-staging one or more logs from a write cache to a backing store, where each log corresponds to a pending write I/O operation by a consumer. The method further includes determining when no log remains in the write cache for de-staging to the backing store and initiating the pass-through mode by routing new write I/O requests directly to the backing store instead of the write cache.
