Abstract:
A data storage erasure system may have a host connected to a plurality of data storage devices via a network controller with each of the plurality of data storage devices and the network controller connected to a pods controller and each of the plurality of the data storage devices having a device controller. A rebuild strategy can be generated with a rebuild module connected to the plurality of data storage devices, the network controller, and the pods controller. The rebuild strategy may be directed to minimize data rebuild times in the event of a failure in the plurality of data storage devices by executing the rebuild strategy in response to a detected or predicted failure in at least one data storage device of the plurality of data storage devices.
