    Abstract: A system comprises one or more storage entities (SEs) each configured to store data for applications that rely on higher levels of data integrity, wherein each of the SEs has its own cryptographic identity in the form of a unique root identity key pair of public and private keys created at manufacturing time. Each SE generates one or more SE-specific asymmetric data owner keys upon invocation of a smart contract by a prospective data owner. The system further comprises a distributed ledger provisioned to the SEs and configured to maintain all public keys and/or public key certificates of the SEs. The system also comprises a key manager configured to hold all SE-specific data owner public keys and SE data access control keys, wherein the data stored on the SEs is protected by the SE-specific data access control keys wrapped by the SE-specific data owner keys based on current data ownership.

    Abstract: A composite layout to store one or more extents of a data object in a first storage system and one or more extents of the data object in a second, different storage system. The first storage system may be configured for the efficient storage of small chunks of data such as, e.g., chunks of data small than the addressable block size of the storage devices used by the storage systems.

    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.
