Abstract: A storage unit is disclosed. The storage unit may include storage for a component codeword. The component codeword may be stored in a block in the storage. The block may also store a block codeword. An interface may receive a read request for a chunk of data from a host and may send the chunk of data to the host. A circuit may read the component codeword from the block in the storage. An error correcting code (ECC) decoder may determine the chunk of data based at least in part on the component codeword.

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.

Abstract: A system is disclosed. A first storage device may supporting a cache coherent interconnect protocol, the cache coherent interconnect protocol including a block level protocol and a byte level protocol. A second storage device may also support the cache coherent interconnect protocol. A redundant array of independent disks (RAID) circuit may communicate with the first storage device and the second storage device. The RAID circuit may apply a RAID level to the first storage device and the second storage device. The RAID circuit may be configured to receive a request using the byte level protocol and to access data on the first storage device.
