Abstract

The invention provides an all-flash system data management method and system, the all-flash system comprises a plurality of nodes, the method comprises the following steps: two adjacent nodes form a domain logically, and the first node and the last node also form a domain logically to form a closed loop; one node is selected in each domain to create a simple volume, the node for creating the simple volume in each domain is a main node, and the other node is a standby node; each node belongs to two domains, and a main node of one domain is also a standby node of the other domain; when a request for accessing the simple volume is received, request processing is carried out through a node for creating the simple volume; when one node in the domain fails, a normal node of the associated domain is added into the domain where the node fails; when the node with the fault recovers to be normal, the node is added into the original domain again; and the associated domain is another domain where the standby node in the same domain as the fault node is located. The reliability and availability of the storage system are improved.

Description

technical field [0001] The invention relates to the technical field of data center data management, in particular to a data management method and system for an all-flash system. Background technique [0002] Thin volume is a data management method designed to optimize the utilization of storage space. Unlike the fixed-size storage space allocated to users at one time, thin volume only allocates the storage space actually used by users. In a dual-controller environment, two storage nodes form a storage system, one of which acts as the primary node for the thin volume, processing read and write requests, metadata transactions, etc., and the other node acts as the standby node for the thin volume, to back up the primary Metadata for the thin volume on the node. When a node of the dual controller fails, all thin volumes are processed by a single node, which not only degrades performance, but also cannot guarantee metadata security. Contents of the invention [0003] Aiming a...
