    Abstract: A method for storing data in a storage system having solid-state memory is provided. The method includes determining portions of the solid-state memory that have a faster access rate and portions of the solid-state memory that have a slower access rate, relative to each other or to a threshold. The method includes writing data bits of erasure coded data to the portions of the solid-state memory having the faster access rate, and writing one or more parity bits of the erasure coded data to the portions of the solid-state memory having the slower access rate. A storage system is also provided.

    Abstract: 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 housed 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 according to a plurality of policies. 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.
