Abstract
A network storage server receives multiple write requests from a set of clients via a network and internally buffers multiple data blocks written by the write requests. At a consistency point, the storage server commits the data blocks to a nonvolatile mass storage facility. The consistency point process includes using a storage operating system in the network storage server to compress the data blocks, encrypt selected data blocks, and store the compressed and (possibly) encrypted data blocks in the nonvolatile mass storage facility. Data blocks can also be fingerprinted in parallel with compression and/or encryption, to facilitate subsequent deduplication. Data blocks can be indexed and classified according to content or attributes of the data. Encryption can be applied at different levels of logical container granularity, where a separate, unique cryptographic key is used for each encrypted data container.
