    • 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。

    • Disclosed herein are cylinder forming apparatuses for making nonwoven webs. In one embodiment, a cylinder forming apparatus has a first source configured to dispense a first fluid flow stream, and a second source configured to dispense a second fluid flow stream, wherein at least the first fluid flow stream comprises a fiber; an arcuate mixing partition downstream from the one or more sources, the arcuate mixing partition positioned between the first and second flow streams, the apparatus defining one or more openings that permit fluid communication between the two flow streams; and a cylindrical receiving region situated downstream from the sources and proximal to the first flow stream and designed to receive at least a combined flow stream and form a nonwoven web by collecting fiber from the combined flow stream. Methods of using the apparatuses are also disclosed.
    • 本文公开了用于制造非织造纤维网的圆筒形成装置。 在一个实施例中,圆筒形成装置具有构造成分配第一流体流动流的第一源和被配置为分配第二流体流动流的第二源,其中至少第一流体流包括纤维; 一个或多个源下游的弧形混合分隔件,位于第一和第二流动之间的弓形混合分隔件,该装置限定允许两个流动流之间的流体连通的一个或多个开口; 以及位于源的下游并且靠近第一流动流的圆柱形接收区域,并被设计成接收至少一个组合的流动流并通过从组合的流动流收集纤维形成非织造纤维网。 还公开了使用该装置的方法。
