The invention discloses a block-level distributed storage system and a data reading-writing method thereof. The storage system comprises a client, a meta server, a block server and at least one piece of physical storage equipment, wherein the client is used for initiating various applications by a user; the meta server is connected with the client, and is used for providing a virtual disk virtualized from the physical storage equipment and forwarding I / O (Input / Output) from the client to the physical storage equipment; the block server is communicated with the meta server, and is used for providing a physical storage space in which a block is taken as a unit; and the at least one physical storage equipment is used for providing a practical physical storage space. The distributed storage system is based on the physical storage equipment, and is of block level, so that any operation system or file system can be conveniently managed; and moreover, data do not pass through a file system, so that the data transmission speed is increased.
Description
technical field [0001] The invention relates to a storage system and an application method thereof, in particular to a block-level distributed storage system and a data reading and writing method thereof. Background technique [0002] At present, most information systems are centered on servers and clients, and storage systems are located in peripheral devices. However, in recent years, with the acceleration of the social informatization process, the amount of information has increased sharply, the number of web pages is in units of 100 million, and the storage capacity of each enterprise has increased exponentially. [0003] A distributed storage system (Distribute Storage) is to store data in a distributed manner on multiple independent physical storage devices (eg, disks). Compared with this, the traditional network storage system uses a centralized storage server to store all data. The storage server becomes the bottleneck of system performance and the focus of reliabil...
