    摘要： A plurality of storage nodes in a single chassis is provided. The plurality of storage nodes in the single chassis is configured to communicate together as a storage cluster. Each of the plurality of storage nodes includes nonvolatile solid-state memory for user data storage. The plurality of storage nodes is configured to distribute the user data and metadata associated with the user data throughout the plurality of storage nodes such that the plurality of storage nodes maintain the ability to read the user data, using erasure coding, despite a loss of two of the plurality of storage nodes. A plurality of compute nodes is included in the single chassis, each of the plurality of compute nodes is configured to communicate with the plurality of storage nodes. A method for accessing user data in a plurality of storage nodes having nonvolatile solid-state memory is also provided.

    摘要： A storage controller coupled to a multi-tenant storage array receives a request from a client device to write a data block to a volume resident on the storage array, wherein the client device is associated with a tenant of the storage array. The storage controller determines a tenant identifier associated with the tenant, generates a hash value for the data block based at least in part on the data block and the tenant identifier, and performs at least one data deduplication operation on the data block using the hash value by determining whether the hash value matches with any of the plurality of previous hash values that are identified in a deduplication map. Responsive to determining that the hash value does not match with any of the plurality of previous hash values that are identified in the deduplication map, the hash value is stored in the deduplication map.

    摘要： Determining active membership among storage systems synchronously replicating a dataset, where determining active membership includes: detecting, by a particular storage system of the storage systems, a communication fault with one or more of the storage systems, where the particular storage system is configured to request mediation from a mediation target; determining that at least one of the one or more storage systems is configured to request mediation from the mediation target responsive to the communication fault; and responsive to determining that one or more of the storage systems is configured to request mediation from the mediation target, determining whether to request mediation from the mediation target.

    摘要： Mediating between storage systems synchronously replicating a dataset, including: requesting, by a first storage system in response to detecting a triggering event, a lock for a shared resource from a mediation service; requesting, by a second storage system in response to detecting the triggering event, the lock for the shared resource from the mediation service; and responsive to acquiring the lock from the mediation service, the first storage system, instead of the second storage system, processing data storage requests directed to the dataset that is synchronously replicated across the first storage system and the second storage system.

    摘要： A method for proactively rebuilding user data in a plurality of storage nodes of a storage cluster is provided. The method includes distributing user data and metadata throughout the plurality of storage nodes such that the plurality of storage nodes can read the user data, using erasure coding, despite loss of two of the storage nodes. The method includes determining that one of the storage nodes is unreachable and determining to rebuild the user data for the one of the storage nodes that is unreachable. The method includes reading the user data across a remainder of the plurality of storage nodes, using the erasure coding and writing the user data across the remainder of the plurality of storage nodes, using the erasure coding. A plurality of storage nodes within a single chassis that can proactively rebuild the user data stored within the storage nodes is also provided.

    摘要： Handling fingerprint collisions in a storage system that includes one or more storage devices, including: determining whether a fingerprint associated with a first data segment matches a fingerprint associated with a data segment stored within the storage system; responsive to determining that the fingerprint associated with the first data segment matches the fingerprint associated with the data segment stored within the storage system, determining whether the first data segment matches the data segment stored within the storage system; and responsive to determining that the first data segment does not match the data segment stored within the storage system, resolving a fingerprint collision between the first data segment and the data segment stored within the storage system.
