Abstract: According to one general aspect, an apparatus may include a regeneration-code-aware (RCA) storage device configured to calculate at least one type of data regeneration code for data error correction. The RCA storage device may include a memory configured to store data in chunks which, in turn, comprise data blocks. The RCA storage device may include a processor configured to compute, when requested by an external host device, a data regeneration code based upon a selected number of data blocks. The RCA storage device may include an external interface configured to transmit the data regeneration code to the external host device.

Abstract: A storage device is disclosed. The storage device may include storage for data. A host interface logic may receive a dataset and a logical address from a host. A stream assignment logic may assign a stream identifier (ID) to a compressed dataset based on a compression characteristic of the compressed dataset. The stream ID may be one of at least two stream IDs; the compressed dataset may be determined based on the dataset. A logical-to-physical translation layer may map the logical address to a physical address in the storage. A controller may store the compressed dataset at the physical address using the stream ID.

Abstract: A method for storing data may include receiving user data at a group of storage devices, wherein the storage devices are interconnected, erasure coding the user data into redundancy blocks at the group of storage devices, and storing the redundancy blocks on at least two of the storage devices. The erasure encoding may be distributed among at least two of the storage devices. The redundancy blocks may be arranged in reliability groups. The redundancy blocks may be grouped by the storage devices independently of the partitioning of the user data by the user. The method may further include recovering data based on redundancy blocks. A storage device may include a storage medium, a network interface configured to communicate with one or more other storage devices, and a storage processing unit configured to erasure code user data into redundancy blocks cooperatively with the one or more other storage devices.
