Abstract: A method for indexing dirty data in a storage system page includes: obtaining a point quantity of storage points in the storage page and dirty data distribution information; creating a bitmap based on the point quantity and dirty data distribution information; creating an extended segment set based on the dirty data distribution information, and obtaining the number of current extended segments in the extended segment set; obtaining, according to the point quantity, a first storage cost for indexing dirty data using the bitmap in the target storage page; obtaining, according to the number of current extended segments and the segment capacity, a second storage cost for indexing dirty data using the extended segments in the target storage page; and determine, according to the first storage cost and the second storage cost, to index the dirty data in the target storage page by means of the bitmap or the extended segments.

Abstract: Disclosed in the present disclosure is a data caching method and apparatus, the data caching method includes the following steps: receiving a data request message sent by a user terminal; if detecting that a cache apparatus does not include the target access data requested by the data request message, then sending the target access data in a storage apparatus to the user terminal; extracting parameter information of the target access data in the storage apparatus, and determining whether the parameter information matches a preset parameter condition; and, if the parameter information matches the preset parameter condition, then transmitting the target access data to the cache apparatus.
