Abstract: 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.

Abstract: 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.

Abstract: A method of operating a storage system is provided. The method includes establishing a security context between a client and the storage system, the security context comprising a single ticket for multiple nodes within the storage system. The method includes distributing a first request to a first blade within the storage system and distributing a second request to a second blade within the storage system. The distributing the first request and the second request includes determining a node for handling the first request and the second request based on data within the single ticket.

Abstract: 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.

Abstract: The method generates a first deduplication map (DDM) level of a DDM pyramid. The DDM pyramid identifies locations of data stored in the persistent storage resource of the deduplication system. The method further determines a first false positive rate target for a first index summary (IS) level of an index pyramid based on a memory footprint for the first IS level and an aggregate false positive rate target for the index pyramid. The first IS level accelerates lookup into the first DDM level. The first false positive rate target indicates a rate that a hit for a value found in the first IS level is not found in the first DDM level. The method also generates the first IS level with a first false positive rate based on the determined first false positive rate target.
