Embodiment Construction

[0022] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0023] like figure 1 , figure 2 As shown, the system of the present invention includes a volume management node (SuMaster), a metadata management node (Master), a block data storage node (Data Node), a user mount client (MountClient) and a management monitoring center (NMC).

[0024] The volume management node maintains the information of all metadata server sub-clusters, and provides the metadata server identification, IP address and port number information for the mounting client, including the main volume management server (SuperMaster) and the backup volume management server (Slave SuperMaster). , The standby volume management server provides external services through the same VIP (virtual IP), and the primary and secondary volume management servers add configuration and maintain a unified state through the monitoring center.

[0025] The metadat...

Abstract

The invention discloses a super-large-scale low-cost storage system. The system comprises a volume management node, a metadata management node, a block data storage node, a user mount client and a management monitoring center. According to the system, the problems, such as poor usability, low integration level, weak expansibility and relatively high cost, in the conventional storage scheme are solved, and the super-large-scale low-cost storage system which is high in reliability, excellent in performance, easy to maintain, strong in expansibility and high in density is realized. According to the system established by the invention, the volume management node and the metadata management node both adopt a dual-computer hot standby mode, and thus, the system reliability is improved greatly.

Description

technical field [0001] The invention relates to the technical field of computer and network information, in particular to an ultra-large-scale low-cost storage system. Background technique [0002] With the rapid development of the information age, the explosive growth of the amount of information has become a feature of the times, and the subsequent problem is the storage of massive data. The traditional hard disk storage is obviously difficult to meet the demand. The DAS that appeared later (Direct-Attached Storage--direct-connected storage) storage method solves the problem of storing data volume, but separate DAS storage forms islands. When a storage capacity is saturated, even other DAS devices have spare capacity. Buying a new storage device, and adding a new server also requires a new DAS, the storage cost is high, and later NAS (Network Attached Storage--Network Attached Storage) and SAN (Storage Area Network--storage network) solved the problem. However, as the amo...
