摘要： Embodiments of the present technical solution relate to the technique field of storage, and disclose a server and a method for the server to access a volume. The method comprises: determining, from a first list, a block that needs to be accessed according to an access offset of a volume that needs to be accessed; determining, from a second list, a storage controller corresponding to the block that needs to be accessed according to the determined block; and sending a data reading request or a data writing request to the storage controller corresponding to the block that needs to be accessed to process. Embodiments of the present invention can reduce time delay when the data reading request or the data writing request of the server reaches the block that needs to be accessed.

摘要翻译： 本技术方案的实施例涉及技术存储领域，并且公开了用于服务器访问卷的服务器和方法。 该方法包括：根据需要访问的卷的访问偏移从第一列表确定需要被访问的块; 根据所确定的块，从第二列表确定与需要被访问的块相对应的存储控制器; 以及将数据读取请求或数据写入请求发送到与需要访问的块对应的存储控制器进行处理。 当服务器的数据读取请求或数据写入请求到达需要访问的块时，本发明的实施例可以减少时间延迟。
