摘要： Methods and systems for managing I/O requests in a secure storage appliance are disclosed. One method includes receiving a plurality of I/O requests at the secure storage appliance, each I/O request associated with a block of data and a volume, each volume associated with a plurality of shares stored on a plurality of physical storage devices. The method further includes storing a plurality of blocks of data in buffers of the secure storage appliance, each of the blocks of data associated with one or more of the plurality of I/O requests. The method also includes associating a state with each of the blocks of data, the state selected from a plurality of states associated with processing of an I/O request. The method includes determining the availability of a resource in the secure storage appliance, the resource used to process an I/O request of a buffer, and, upon determining that the resource is available, applying the resource to a block of data in the buffer and updating the state associated with the block of data.
