Abstract

This application discloses a storage device cluster. The storage device cluster can support some storage devices to go offline and upgrade the memory without interrupting the business. After the storage device comes online again, it will detect whether there is a new The unactivated memory, and determine whether the memory activation conditions are met, if so, activate the unactivated memory on each storage device in the cluster, otherwise limit the storage device to use the unactivated memory, so as to ensure that each storage device in the cluster The activated memory size is always the same. In the end, the purpose of online dynamic adjustment of device memory size is achieved, the capital cost of replacing or adding new devices due to business increase is reduced, and business interruption caused by device replacement is also avoided. In addition, the present application also provides a storage device cluster management method, device and storage device, the functions of which are corresponding to those of the above storage device cluster.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular to a storage device cluster, a management method and device for a storage device cluster, and a storage device. Background technique [0002] In today's era of information explosion, the amount of user data is increasing rapidly, and new business functions are rich and colorful. This also ushers in new challenges for the SAN storage devices at the back end of the server. SAN storage devices also need to upgrade software or add more Business functions. When the device software is upgraded and business functions are added to a certain extent, the size of the running memory may not be sufficient. In order to maximize the value of original old assets, computer room operators are generally unwilling to simply discard old assets and replace them with new equipment. [0003] To sum up, at present, due to data growth and business increase, the storage device cluster has t...
