Abstract: A dynamic scalable error correction coding (ECC) scheme for a data storage system involves a system controller predicting a type and/or amount of ECC needed to reconstruct data to be stored on a particular data storage device(s) based on operational data integrity information accessed from the array of data storage devices. Thus, redundancy does not need to be allocated unless required. The devices may be logically grouped into subsets according to common characteristics, whereby the prediction made for a device in a subset may be based on the data integrity information from that subset, as well as from other relevant subsets.

Abstract: To provide enhanced operation of data storage devices and systems, various systems, apparatuses, methods, and software are provided herein. In a first example, a data storage array is presented. The data storage array includes a plurality of data storage devices positioned in an enclosure, each of the plurality of data storage devices comprising rotating media for storage and retrieval of data. The data storage array includes one or more temperature sensors configured to measure thermal information associated with the data storage array. The data storage array includes a management controller configured to monitor the thermal information and establish adjustments to at least seek operations of the plurality of data storage devices to control a temperature in the enclosure.
