Abstract

The embodiment of the invention discloses a memory array operation method and device. The method may comprise the steps of receiving an operation instruction issued by a target business object for a cache of a memory array, wherein service objects supported by the memory array are divided into at least one performance group, and traffic allowed to be operated is pre-calculated for each performance group; selecting a target performance group to which the target business object belongs from the at least one performance group and judging whether the traffic allowed to be operated of the target performance group has residual traffic or not; if the traffic allowed to be operated of the target performance group has the residual traffic, responding to the operation instruction; and if the traffic allowed to be operated of the target performance group has no residual traffic, refusing the operation instruction. According to the embodiment of the method and the device, the performance deterioration problem of integrated memory can be solved.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a method and device for operating a storage array. Background technique [0002] With the development of storage technology, storage arrays often support multiple functions, such as: supporting converged storage of Network Attached Storage (NAS) and Storage Area Network (SAN), or supporting both local access and Heterogeneous logical unit number (Logical Unit Number, Lun) storage, or there are often many different services inside the storage array. For example, customers may configure thin provisioning (thin) Lun, normal (thick) Lun, and snapshot services at the same time. And Lun implemented based on Redirect On Write (ROW) technology. Moreover, existing storage arrays often provide a cache (Cache) function to speed up read and write efficiency. However, the cache resources of the storage array may be shared by many business objects, and the performance of different b...
