Abstract

The invention discloses a control method and system for a cluster storage network parallel load. The method comprises the steps of when the data request of a client end is detected, determining the storage nodes of the cluster storage network of a data block for storing and corresponding to the data request; obtaining the maximum link transmission band width of the cluster storage network, allocating a corresponding band width for each determined storage node according to the obtained maximum link transmission band width and the number of the determined storage nodes; and controlling the allocated band width of each determined storage node, and sending the data slot of the data block corresponding to the stored data request to the client end to generate the whole data block. The control method and system for the cluster storage network parallel load enable each storage node to be in a balanced state in the resource competing by sending each determined storage node to the client end according to the allocated band width, so the data request of the client end is timely sent, the finishing time of the data request is shortened, and the real throughput of the client end is improved.

Description

technical field [0001] The invention relates to the field of cluster storage, in particular to a method and system for controlling parallel loads of a cluster storage network. Background technique [0002] The cluster storage network is generally built on the standard high-speed and low-latency TCP / IP Ethernet, and in order to obtain high data storage reliability, scalability and storage performance, the cluster storage network usually divides data blocks into strips (called striping) is stored on multiple storage nodes, so when the client requests to read a data block, all storage nodes in the cluster storage network that store the data fragments of the data block currently requested to read will be synchronized In response, this communication mode is also called many-to-one (M:1) communication mode. [0003] In the (M:1) communication mode, due to the limited bandwidth of the switch cache or the data transmission link from the client to the switch, when multiple storage n...
