Abstract

The invention provides an LUN data replication method and device which are applied to storage equipment. The storage equipment comprises a to-be-copied source LUN and a buffer area corresponding to the source LUN, and the buffer area is used for storing data records of to-be-copied data in the source LUN generated according to a write-in sequence and the to-be-copied data. In the application, the storage equipment supports a plurality of copy modes, the influence of the current copy mode on the front-end service performance of the storage device is determined by monitoring the use condition of the buffer corresponding to the source LUN in real time, and when it is determined that the current copy mode cannot meet the front-end service processing performance requirement, switching is carried out to other copying modes which can meet the front-end service processing performance requirements. Namely, the purpose of improving the overall performance of the storage equipment is achieved by dynamically adjusting the copying mode.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular to a method and device for duplicating LUN data. Background technique [0002] Storage devices generally have data protection features, and data replication, as a technology that can realize data protection, has been widely used in storage devices. [0003] At present, for data replication of logical unit numbers (English: Logical Unit Number, abbreviation: LUN) in storage devices, there are multiple replication modes available, for example, periodic replication mode, continuous replication mode according to the write order, and the like. The specific replication mode is usually pre-specified by the administrator. [0004] However, no matter which copy mode is specified, it is generally impossible for the single copy mode to meet the performance requirements of the storage device in real time. Contents of the invention [0005] In view of this, the present appli...
