    Abstract: A method and system for performing data manipulation on a storage device is disclosed. A data manipulation command is created on a computing device, wherein the computing device is separate from the storage device. The computing device is a client or a server that requests services of a storage system to store data on a storage medium. The computing device and the storage device are connected over a network. The computing device executes a host application, and its data is stored on the medium. The computing device issues a command to the storage device to be performed on the data. The storage device executes the command and sends the result to the computing device. As a result, the data is not sent to the computing device for manipulation.

    Abstract: A system and method are provided for estimating compressibility of data in a storage device. This is accomplished by actually running a compression algorithm on at least one data element in a storage device, without necessarily storing the compressed data. By this feature, the results of the compression may be compared with the original data element, to gauge an extent to which a compression algorithm is effective in compressing data in the storage device. To this end, in various embodiments, a user may be better able to estimate compression algorithm effectiveness before actually implementing the same.

    Abstract: The present invention provides a streaming media cache configured to select a timing interval, chosen from a set of one or more predetermined timing intervals, for each client that requests a data stream from the streaming media cache. Illustratively, clients requesting data streams below a predetermined bit rate (“bandwidth”) are assigned longer timing intervals than clients requesting data streams above the predetermined bit rate. More specifically, because the server can accommodate a larger number of relatively low-bandwidth clients than relatively high-bandwidth clients, the server selects timing intervals of longer duration for the relatively low-bandwidth clients so it may have more time to schedule send times for their requested packets.

    Abstract translation: 本发明提供一种流媒体缓存，其被配置为从为流媒体高速缓存请求数据流的每个客户端选择从一组或多个预定定时间隔中选择的定时间隔。 说明性地，请求数据流低于预定比特率（“带宽”）的客户端被分配比客户端更长的定时间隔，该客户端请求高于预定比特率的数据流。 更具体地说，由于服务器可以容纳比相对较高带宽的客户端更多数量的相对低带宽的客户端，所以服务器为相对低带宽的客户端选择较长持续时间的定时间隔，因此可以有更多的时间调度发送时间 他们要求的数据包。

    Abstract: A storage server is configured to receive a request to store a data block from a client. The request to store the data block is serviced by the storage server by compressing the data block into a compression group which includes a number of compressed data blocks. The storage server stores the compression group in a non-volatile memory and flushes the compression group from the non-volatile memory to a physical storage device in response to reaching a consistency point. By compressing data to be stored in system memory of a storage servers the amount of data that can be processed during a given time period by a data storage system is increased. Furthermore, an increase in performance can be achieved at a lower cost, since the cost of additional physical system memory modules can be avoided,

    Abstract translation: 存储服务器被配置为从客户端接收存储数据块的请求。 存储数据块的请求由存储服务器通过将数据块压缩成包括多个压缩数据块的压缩组来服务。 存储服务器将压缩组存储在非易失性存储器中，并响应于达到一致性点将压缩组从非易失性存储器刷新到物理存储设备。 通过压缩要存储在存储服务器的系统存储器中的数据，数据存储系统在给定时间段内可以处理的数据量增加。 此外，可以以更低的成本实现性能的提高，因为可以避免额外的物理系统存储器模块的成本，

    Abstract: A storage server maintains an active file system and at least one read-only, persistent point-in-time image (RPPI) of the active file system. The booting time of the storage server is reduced by delaying the mounting of the RPPI(s) until the storage server receives a request to access a corresponding RPPI after the storage server has already booted.

    Abstract: Provided is a method and system for reducing duplicate buffers in buffer cache associated with a storage device. Reducing buffer duplication in a buffer cache includes accessing a file reference pointer associated with a file in a deduplicated filesystem when attempting to load a requested data block from the file into the buffer cache. To determine if the requested data block is already in the buffer cache, aspects of the invention compare a fingerprint that identifies the requested data block against one or more fingerprints identifying a corresponding one or more sharable data blocks in the buffer cache. A match between the fingerprint of the requested data block and the fingerprint from a sharable data block in the buffer cache indicates that the requested data block is already loaded in buffer cache. The sharable data block in buffer cache is used instead thereby reducing buffer duplication in the buffer cache.
