The distributed storage system is a large number of common PC servers interconnected through the Internet to provide storage services as a whole. What are the characteristics?




Accept answer 1:

Characteristics of Distributed Storage System

(1) Large capacity, the system nodes can use general-purpose X86 architecture storage servers as building units, and storage nodes can be expanded horizontally and infinitely according to user needs, and form a unified shared storage pool;

(2) High performance, providing aggregated IOPS and throughput several times higher than traditional storage. In addition, it can grow linearly with the expansion of storage nodes. The dedicated metadata module can provide very fast and accurateData retrieval and positioning to meet the needs of fast response of front-end business;

(3) High reliability, the entire system has no single point of failure, and data security and business continuity are guaranteed.Each node can be regarded as a hard disk, and there are special data protection strategies between node devices, which can realize device-level redundancy of the system, and can replace damaged hard disks or node devices online;

(4) Easy to expand. The system can support online seamless dynamic horizontal expansion. In the case of adopting the redundancy strategy, the online and offline of any storage node has no impact on the front-end business, and it is completely transparent.And the system can choose automatic load balancing after expanding new storage nodes, and the pressure of all data is evenly distributed on each storage node;

(5) Easy to integrate, compatible with any brand of X86 architecture general storage server, it can be easily implemented in a standard IP/IB network environment without changing the original network architecture;

(6) Easy to manage, the entire system can be configured and managed through a simple WEB interface, the operation and maintenance is simple, and the management cost is extremely low. An administrator can easily manage a PB-level storage system.
