A system and method for managing tables in a storage system is described.

Flash system having multiple fingerprint tables

Tiering snapshots across different storage tiers, including: creating a snapshot of a dataset, wherein the snapshot includes user data and metadata; offloading the snapshot of the dataset to a first storage level storage system; and migrating, in accordance with a lifecycle policy and via one or more copy offload operations, the snapshot from the first storage level storage system to a second storage level storage system.

Tiering snapshots across different storage tiers

A storage system stores objects in a bucket at a storage device of the storage system. Each of the objects has a corresponding version. A processing device generates a snapshot of the bucket. The snapshot captures the corresponding version of each of the objects at a time associated with the generation of the snapshot.

Bucket versioning snapshots

A system and method comprising: receiving a request to write data stored at a first range of a first volume to a second range of a second volume, where first metadata for the first range of the first volume is associated with a range of physical addresses where the data is stored in the storage system; and responsive to receiving the request: creating second metadata for the second range of the second volume, wherein the second metadata is associated with the range of physical addresses where the data is stored in the storage system; and associating the second volume with the second metadata.

Lightweight copying of data using metadata references

A storage system has filtered views of data. The storage system receives a read request for a filtered view of data in memory. The read request is associated with one or more permissions for viewing the data. The storage system identifies a subset of the data, based on the one or more permissions. The storage system provides the filtered view. The filtered view includes the subset of the data.

Utilizing data views to optimize secure data access in a storage system

A method of operating an object-based storage system, practiced by the storage system, is provided. The method includes establishing a plurality of buckets for objects, in the storage system and establishing a plurality of bucket views in the storage system, each bucket view supporting access to objects of one of the plurality of buckets. The method includes accessing an object of a bucket through one of the plurality of bucket views.

Bucket views

An apparatus for artificial intelligence acceleration is provided. The apparatus includes a storage and compute system having a distributed, redundant key value store for metadata. The storage and compute system having distributed compute resources configurable to access, through a plurality of authorities, data in the solid-state memory, run inference with a deep learning model, generate vectors for the data and store the vectors in the key value store.

Search acceleration for artificial intelligence

A method including, responsive to receiving a request identifying a volume and indicating a command to take a snapshot of the volume, mapping a second logical grouping of data to reference the first logical grouping of data, and remapping the first volume to map to the second logical grouping of data instead of the first logical grouping of data such that the first volume remains addressable with similar access permissions before and after creating the snapshot. The method also includes, in response to receiving a write request targeting the second logical grouping, splitting the second logical grouping into a plurality of ranges including a first range and a second range; wherein the first range of the second logical grouping maps to the first logical grouping, and the write request is performed on the second range of the second logical grouping.

Generating volume snapshots

A method of replication in a distributed storage system, performed by the distributed storage system is provided. The method includes managing a first index for data or metadata in a first storage system, the first storage system having a first partitioning scheme. The method includes managing a second index for data or metadata in a second storage system, the second storage system having a second partitioning scheme. The method includes replicating the data or metadata from the first storage system to the second storage system, translating an identifier of the data or metadata from the first storage system, and mapping the replicated data or metadata into the second partitioning scheme, via the translating of the identifier of the data or metadata from the first storage system.

Data replication in a storage system

Optimizing generalized transfers between storage systems including identifying, by a first storage system, a request to transfer source data from the first storage system to a second storage system, wherein the first storage system implements a first storage architecture and the second storage system implements a second storage architecture; identifying difference information between the source data that is stored on the first storage system using the first storage architecture and existing data that is stored on the second storage system using the second storage architecture; and transferring, in dependence upon the difference information, a subset of the source data from the first storage system to the second storage system.

Optimizing generalized transfers between storage systems

Writing data using references to previously stored data

Pattern matching using hash tables in storage system

Attributing consumed storage capacity among entities storing data in a storage array includes: identifying a data object stored in the storage array and shared by a plurality of entities, where the data object occupies an amount of storage capacity of the storage array; and attributing to each entity a fractional portion of the amount of storage capacity occupied by the data object.

Tracking storage consumption in a storage array

A method for tracking valid and invalid sequence numbers in a storage system, performed by a processor, is provided. The method includes establishing a table as a key value store in memory in the storage system. The table has sequence numbers as keys and represents valid sequence numbers and invalidated sequence numbers of an open-ended sequence relating to storage of data or metadata in the storage system. The method includes adding to the table an entry that records a first plurality of consecutive sequence numbers, as a first range-valued key associated with a first value indicating the first plurality of consecutive sequence numbers is valid. The method includes adding to the table an entry that records a deletion of a second plurality of consecutive sequence numbers, as a second range-valued key associated with a second value indicating the second plurality of consecutive sequence numbers is invalid.

Sequence invalidation consolidation in a storage system

Protecting data stored on a storage system through the use of different storage levels, including: creating a snapshot of a dataset stored on a storage system, wherein the snapshot includes user data and metadata, and wherein the metadata describes the storage layout of the dataset, offloading the snapshot to a first storage level storage system, and migrating, in accordance with a lifecycle policy, the snapshot from the first storage level storage system onto a second storage level storage system.
