Methods and systems for managing distributed storage servers are described. The storage servers may be selected and divided into multiple sequences and multiple virtual node groups. Each sequence of the multiple sequences may include a predetermined number of storage servers, and each virtual node group may include a set of storage servers of the multiple sequences. Data may be transferred to storage severs of a virtual node group. If the storage servers have instantaneous or temporary malfunctions, the data may be transferred to temporary storage servers and then transferred back the storage servers after being revived. If the storage servers have permanent malfunctions, the data may be transferred to the temporary storage servers. The storage servers may be replaced using the temporary storage servers.

Implementing Web access includes finding a Web module and a Web module method associated with a client request. Based on a parameter declaration of the Web module method, a Web server obtains from a Web context request data that is used to invoke the Web module method. The Web server then stores in a Web context a return value and renders a displayed Web page based on the Web context. In some aspects, implementing Web access further includes analyzing the parameter declaration of the Web module methods and finding a data scope and a data item associated with the request data. In some aspects, implementing Web access further includes generating a Web module instance in response to determination that the instance does not exist.
