Abstract: A method performed by a networking switch in an object storage system. The method includes receiving a first packet from a network comprising an object ID and a data object. The method includes generating a replica for the data object. The method includes generating an object ID for the replica of the data object. The method includes determining a destination storage node for the replica of the data object. The method includes sending a second packet from the networking switch to the destination storage node. The second packet includes the object ID for the replica of the data object and the replica of the data object.

Abstract: Examples described herein relate to a network interface device comprising circuitry to receive an access request with a target logical block address (LBA) and based on a target media of the access request storing at least one object, translate the target LBA to an address and access content in the target media based on the address. In some examples, translate the target LBA to an address includes access a translation entry that maps the LBA to one or more of: a physical address or a virtual address. In some examples, translate the target LBA to an address comprises: request a software defined storage (SDS) stack to provide a translation of the LBA to one or more of: a physical address or a virtual address and store the translation into a mapping table for access by the circuitry. In some examples, at least one entry that maps the LBA to one or more of: a physical address or a virtual address is received before receipt of an access request.

Abstract: Provided are a method and apparatus for programming non-volatile memory using a multi-cell storage cell group to provide error location information for retention errors. Each storage cell in the non-volatile memory is programmed with threshold voltage levels and each storage cell is programmed from bits from a plurality of pages. A memory controller organizes the storage cells into storage cell groups, each storing m bits of information programmed with the threshold voltage levels. A determination is made of one threshold voltage level to use for each of the storage cells in the storage cell group to program a selected k bits in the storage cell group with threshold voltage levels defining one of a plurality of valid states. The threshold voltage levels for at least one of the storage cells of the storage cell group in any two valid states differ by at least two threshold voltage levels.

Abstract: A method is described. The method includes performing the following with a storage end transaction agent within a storage sled of a rack mounted computing system: receiving a request to perform storage operations with one or more storage devices of the storage sled, the request specifying an all-or-nothing semantic for the storage operations; recognizing that all of the storage operations have successfully completed; after all of the storage operations have successfully completed, reporting to a CPU side transaction agent that sent the request that all of the storage operations have successfully completed.

Abstract: To reduce the cost of ensuring the integrity of data stored in distributed data storage systems, a storage-side system provides data integrity services without the involvement of the host-side data storage system. Processes for storage-side data integrity include maintaining a block ownership map and performing data integrity checking and repair functions in storage target subsystems. The storage target subsystems are configured to efficiently manage data stored remotely using a storage fabric protocol such as NVMe-oF. The storage target subsystems can be implemented in a disaggregated storage computing system on behalf of a host-side distributed data storage system, such as software-defined storage (SDS) system.

Abstract: Provided are a method and apparatus for endurance friendly programming using lower voltage thresholds. A non-volatile memory has storage cells organized as pages programmed using a first number of threshold voltage levels. The storage cells are organized into storage cell groups to which data is written. Each storage cell group is programmed to store a first number of bits of information. A memory controller selects a second number of bits of information from pages less than the first number of bits of information. The memory controller programs the storage cells of the storage cell group using threshold voltage levels from a second number of threshold voltage levels, wherein the second number of threshold voltage levels is less than the first number of threshold voltage levels and comprises a lowest of the first number of threshold voltage levels.
