Problems solved by technology
Whether it is vertical expansion by adding multiple expansion cabinets for SAN storage devices to increase storage capacity, or horizontal expansion by increasing the number of SAN storage devices to improve storage performance, the storage performance of the overall SAN storage system is often only that of a single storage device. The upper limit of performance, it is difficult to break through the bottleneck of bandwidth performance provided externally

The invention discloses a distributed storage system. The system comprises a shunt device and multiple storage devices, the shunt device is connected with each storage device, the shunt device is usedfor dividing target data when a storage request aiming at the target data is received, and multiple target data blocks are obtained; aiming at each target data block, the target storage device storing the target data block is determined, and the target data block is sent to the target storage device, so that the target storage device receives and stores the target data block, wherein the target storage device is one of the multiple storage devices. According to the technical scheme, the upper limit of the storage performance of the storage system is the sum of the upper limits of the performance of the multiple storage devices, the capacity of providing storage services for outsiders can be improved, the system is externally shown as one storage device taking the shunt device as a representative, and configuration information of other devices does not need to be changed for the storage system. The invention further discloses a distributed storage method. The corresponding advantages are achieved.
Description
technical field [0001] The present invention relates to the technical field of storage, in particular to a distributed storage system and method. Background technique [0002] With the increase of Internet business volume, the rapid growth of access volume and data flow, the storage capacity of the storage system also increases accordingly. [0003] In recent years, SAN storage system has become more prominent among many storage systems. The main equipment of the SAN storage system includes storage switches and SAN storage devices. In a SAN storage system, multiple servers can be connected to a SAN storage device through a storage switch, and the SAN storage device provides storage services. [0004] When a SAN storage system provides external storage services, there is usually a bottleneck in the bandwidth performance provided by a single SAN storage device. Whether it is vertical expansion by adding multiple expansion cabinets for SAN storage devices to increase storage...
