    Abstract: A method may include operating a first storage device and a second storage device as a redundant array, operating the first storage device in a fault resilient mode with at least partial read capability based on a fault condition of the first storage device, and rebuilding information from the first storage device on a spare storage device based on the fault condition of the first storage device. Rebuilding information from the first storage device on the spare storage device may include copying information from the first storage device to the spare storage device. The information from the first storage device may include data and/or parity information. The method may further include reading first information for a read or write operation from the first storage device based on a rebuild point of the spare storage device.

    Abstract: A method for managing system resources includes receiving, by a storage device, a Quality of Service (QOS) parameter from a host. The storage device selects a first index type, from among index types, for a first index based on the QoS parameter and a computational load metric. The index types include one index type having an index structure that is a tree structure, a list structure, or a hash structure. The index structure is different from an index structure of another index type of the index types. The storage device sends feedback to the host regarding the first index type for the host to use in identifying a second index type for a second index to manage a computational load. The storage device accesses the data using the first index based on a processing of the user request, by the host, using the second index.
