摘要： Techniques are disclosed relating to storage device failover. In one embodiment, a plurality of storage devices are represented as cluster resources to a cluster resource manager that manages cluster resources on a plurality of cluster nodes. An indication may be received that a failover operation is requested with respect to one of the plurality of storage devices. In response to the indication, the cluster resource manager may initiate the failover operation. In some embodiments, the failover operation includes changing a first access state of the storage device and a second access state of another storage device. In such an embodiment, the storage device and the other storage device may be associated with a logical unit number. In some embodiments, the storage device is located within a first of the plurality of cluster nodes; the other storage device is located within a second of the plurality of cluster nodes.

摘要： Apparatuses, systems, and methods are disclosed for reconfiguring an array of storage elements. A storage element error module is configured to determine that one or more storage elements in an array of storage elements are in error. An array of storage elements stores a first ECC block and first parity data generated from the first ECC block. A data reconfiguration module is configured to generate a second ECC block comprising at least a portion of data of a first ECC block. A new configuration storage module is configured to store a second ECC block and associated second parity data on fewer storage elements than a number of storage elements in an array.

摘要： Techniques are disclosed relating to arranging data on storage media. In one embodiment, a computer system is configured to access a storage array that includes a plurality of storage blocks. The computer system executes a first set of processes and a second set of processes, where the first set of processes operates on selected ones of the plurality of storage blocks to increase a likelihood that the selected storage blocks are operated on by the second set of processes. In some embodiments, the second set of processes determines whether to operate on a storage block based on an amount of invalid data within the storage block. In such an embodiment, the first set of processes increases a likelihood that the storage block is operated on by increasing the amount of invalid data within the storage block.
