Abstract: A network adapter receives a request to store a data block. The data block is sent from the network adapter to a compression module. The compression module generates a compressed data block from the data block. The compressed data block or a reference to the compressed data block is stored in a buffer cache. The compressed data block is stored in nonvolatile memory. It is determined that the compressed data block should be flushed a storage device. In response to determining that the compressed data block should be flushed to the storage device, the compressed data block is flushed from the nonvolatile memory to the storage device.

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 server, 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，可以增加数据存储系统在给定时间段内可处理的数据量。 此外，由于可以避免额外的物理系统存储器模块的成本，因此可以以更低的成本实现性能的提高。

Abstract: Partially overwriting a compression group without decompressing compressed data can consumption of resources for the decompression. A storage server partially overwrites the compression group when a file block identifier of a client's write request resolves to the compression group. The compression group remains compressed while the partial overwriting is performed.
