    • 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 logical container.
    • 网络存储服务器通过网络从一组客户端接收多个写入请求,并且内部缓冲由写入请求写入的多个数据块。 在一致性点,存储服务器将数据块提交到非易失性大容量存储设备。 一致性处理包括使用网络存储服务器中的存储操作系统来压缩数据块,加密所选择的数据块,并将压缩和(可能)加密的数据块存储在非挥发性大容量存储设施中。 数据块也可以与压缩和/或加密并行进行指纹化,以便于后续重复数据删除。 数据块可以根据数据的内容或属性进行索引和分类。 加密可以应用于逻辑容器粒度的不同级别,其中每个加密的逻辑容器使用单独的唯一密码密钥。
