SCHEDULING POLICY FOR QUEUES IN A NON-VOLATILE SOLID-STATE STORAGE |
摘要 |
A method of applying scheduling policies is provided. The method includes distributing user data throughout a plurality of storage nodes through erasure coding, wherein the plurality of storage nodes are within a single chassis coupling the storage nodes as a cluster. The method includes receiving operations relating to a non-volatile memory of one of the plurality of storage nodes into a plurality of operation queues. The method includes evaluating each of the operations in the plurality of operation queues as to benefit to the non-volatile solid-state storage. For each channel of a plurality of channels coupling the operation queues to the non-volatile memory, the method includes iterating a selection and an execution of a next operation from the plurality of operation queues, with each next operation having a greater benefit than at least a subset of operations remaining in the operation queues. |
