Abstract: In an embodiment, a migration of a dataset from a source storage system to a target storage system is initiated, wherein at least one of the source storage system and the target storage system is a cloud-based storage system. The target storage system provides read/write access to the dataset before completing migration of the dataset from the source storage system to the target storage system.

Abstract: Solid state drives with multiple types of addressable memory, where the solid state drives include: a first memory component comprising a plurality of nonvolatile registers; a second memory component comprising flash memory; and one or more controllers configured to: receive a write operation, wherein the write operation indicates a first portion of data to be written to the flash memory and indicates a second portion of data to be written to one or more of the plurality of registers; and atomically write the first portion of the data to the flash memory and the second portion of the data to the one or more of the plurality of registers.

Abstract: A pod, the pod including the dataset, a set of managed objects and management operations, a set of access operations to modify or read the dataset, and a plurality of storage systems, where: management operations can modify or query managed objects equivalently through any of the storage systems, access operations to read or modify the dataset operate equivalently through any of the storage systems, each storage system stores a separate copy of the dataset as a proper subset of the datasets stored and advertised for use by the storage system, and operations to modify managed objects or the dataset performed and completed through any one storage system are reflected in subsequent management objects to query the pod or subsequent access operations to read the dataset.

Abstract: Prioritizing highly performant storage systems for servicing a synchronously replicated dataset: detecting a communication fault between two or more storage systems that are synchronously replicating a dataset; identifying a preferred storage system for winning mediation, including determining that the preferred storage system winning mediation would result in better performance than other storage systems winning mediation; and requesting, by the preferred storage system, mediation from a mediation target.

Abstract: Symmetric storage using a cloud-based storage system, including: receiving, at a cloud-based storage system among storage systems synchronously replicating a dataset, an I/O operation directed to the dataset; determining, in dependence upon the I/O operation, a metadata update describing a mapping of segments of content to an address within a storage object, wherein the storage object includes the dataset; and synchronizing metadata on another storage system of the storage systems by sending the metadata update from the cloud-based storage system to the other storage system to update a metadata representation on the second storage system in accordance with the metadata update.

Abstract: Probabilistic error correction in flash-based storage systems, including: determine that a number of data shards in a data stripe having an unrecoverable error correction code (UECC) error exceeds a number of failed shards allowable under a redundancy level of the data stripe; identifying, in a portion of data in a data shard having the UECC error, a plurality of low-confidence bits, including: performing multiple reads of the portion of data; identifying, as the plurality of low-confidence bits, a plurality of bits having values differing across the multiple reads; and correcting the portion of data by assigning corrected values to the one or more low-confidence bits.
