Storage system capable of managing a plurality of snapshot families and method of snapshot family based read
Abstract:
A method for a snapshot family based reading of data units from a storage system, the method comprises: receiving a read request for reading a requested data entity, searching in a cache memory of the storage system for a matching cached data entity, if not finding the matching cached data entity then: searching for one or more relevant data entity candidates stored in the storage system; selecting, out of the one or more relevant data entity candidates, a selected relevant data entity that has a content that has a highest probability, out of contents of the one or more relevant data entity candidates, to be equal to the content of the requested data entity; and responding to the read request by sending the selected relevant data entity.
Abstract(Chinese):

一种用于从存储系统读取数据单元的基于快照家族的方法，所述方法包括：接收读取请求的数据实体的读取请求，在存储系统的高速缓冲存储器中搜索匹配的缓存数据实体，如果没有找到 所述匹配缓存数据实体然后：搜索存储在所述存储系统中的一个或多个相关数据实体候选者; 从所述一个或多个相关数据实体候选者中选择具有所述一个或多个相关数据实体候选者的内容中具有最高概率的内容的所选相关数据实体等于所请求的内容的内容 数据实体; 以及通过发送所选择的相关数据实体来响应所述读取请求。
