Embodiment Construction

[0030] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] figure 1 It is a schematic diagram of Lun distribution in a storage system in the prior art. like figure 1 As shown, the 8 vertical boxes represent the 8 physical hard disks in the storage system, and the 4 horizontal boxes represent Lun1, Lun2, Lun3 and Lun4 respectively. In the case of high random IO access, multi-Lun co...

Abstract

The embodiment of the invention provides a data object processing method and a device. The method comprises the following steps: obtaining the performance parameters which is input through a man-machine interface module of a memory system by a user and is needed by the creation of a data object; obtaining the maximum performance parameter corresponding to a physical hard disk which is not spanned by a preexisting data object in the memory system; selecting a physical hard disk spanned by the data object according to the performance parameters needed by the data object and the maximum performance parameter corresponding to the physical hard disk which is not spanned by the preexisting data object in the memory system; creating a data object according to the spare capacity of the physical hard disk spanned by the data object; and taking the data object as Lun and address areas, files or catalogs of the Lun, corresponding to a user access request. Due to the adoption of the technical scheme of the embodiment of the invention, the physical hard disk resources in the memory system can be utilized sufficiently in a maximum manner.

Description

technical field [0001] Embodiments of the present invention relate to the field of storage technology, and in particular, to a data object processing method and device. Background technique [0002] The storage system in the prior art includes a plurality of physical hard disks, and a plurality of data objects allocated to the host for convenience of use by the host, for example, the data object here may be a logical volume (Logical Unit Number; hereinafter referred to as Lun; also can be called a logical unit number). [0003] Normally, the distribution of data objects such as Lun follows the principle of automatic balance, and each data object in the storage system is evenly distributed to all physical hard disks in the storage system (or Raid group), that is, each Data objects span all physical hard disks in the storage system (or Raid group). In the storage system, according to the above-mentioned distribution method of data objects, the distribution method of all data...
