Abstract: Disclosed are systems, computer-readable mediums, and methods for receiving client quality of service values associated with a first client. Client metrics of a volume in a storage system are determined for the first client. The client metrics reflect usage of the storage system by the first client. A client load value based is determined upon the client metrics. A quality of service management policy for the first client is determined from a plurality of quality of service management policies based upon the client load value. Each quality of service management policy comprises a formula based on a quality of service parameter. A client target performance value is determined based upon the formula of the quality of service management policy and the received client quality of service values. Performance of the storage system is adjusted for the first client based upon the client target performance value.

Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving a write request that includes data and a client address at which to store the data. The data is segmented into the one or more storage units. A storage unit identifier for each of the one or more storage units is computed that uniquely identifies content of a storage unit. A mapping between each storage unit identifier to a block server is determined. For each of the one or more storage units, the storage unit and the corresponding storage unit identifier is sent to a block server. The block server stores the storage unit and information on where the storage unit is stored on the block server for the storage unit identifier. Multiple client addresses associated with a storage unit with the same storage unit identifier are mapped to a single storage unit.

Abstract: Disclosed are systems, computer-readable mediums, and methods for transforming data in a file system. As part of a recycling process, a determination is made that transformations should be attempted. A data block is determined to be in use by at least one user of the storage system. If a transformation should be attempted on the data block is determined. Parameters associated with the performance of the file system can be used in this determination. A type of transformation to be done is determined. The data block is transformed based upon the selected transformation. The transformed data block is written to the storage system. As part of the recycling process, the transformation requires no additional input/output requests.
