Abstract: Detection and reduction of unaligned input/output (“I/O”) requests is implemented by a storage server determining an alignment value for data stored by the server within a storage system on behalf of a first client, writing the alignment value to a portion of the volume that stores the data for the first client, but not to a portion of the volume that stores data for a second client, and changing a location of data within the portion of the volume that stores the data for the first client, but not a location of data in the portion of the volume that stores data for the second client, to an alignment corresponding to the alignment value. The alignment value is applied to I/O requests directed to the portion of the volume that stores the data blocks for the first client after the location of the data blocks has been changed.

Abstract translation: 检测和减少未对齐的输入/输出（“I / O”）请求由存储服务器实现，该存储服务器代表第一客户机确定存储系统内的服务器所存储的数据的对准值，将对准值写入一部分 存储第一客户端的数据的卷，而不存储存储第二客户端的数据的卷的一部分，以及改变存储第一客户端的数据的卷的部分内的数据的位置，但是 不是将存储第二客户端的数据的卷的部分中的数据的位置设置为与对齐值相对应的对齐。 在数据块的位置已经改变之后，对齐值被应用于指向存储第一客户端的数据块的卷部分的I / O请求。
