Problems solved by technology

It is conceivable that the back-end port board will be very busy at this time, and its processing speed is likely to become the bottleneck of the entire business
Moreover, this kind of bottleneck caused by the slowdown of the processing speed of the back-end port board is relatively hidden, and it is not easy to find out the cause
Even if the cause is found, it will be a time-consuming and labor-intensive task to reorganize the data

Embodiment Construction

[0028] Because the logical unit number of a virtual disk is irrelevant to the location of the physical disk, RAID type, and connection components, that is to say, the logical unit number of a virtual disk is only used to identify the virtual disk, which is irregular follow. Therefore, it is very difficult to perform appropriate allocation of virtual resources based only on the logical unit numbers of the virtual disks. Moreover, even if a virtual disk that meets the requirements is selected, it is very difficult to manage it in an orderly manner.

[0029] In order to solve the above technical problems, the embodiment of the present invention proposes a method for dividing disks to hosts, which can also be called a method for virtual disk allocation. The operation process of this method is as follows figure 2 As shown, it mainly includes the following steps:

[0030] Step 101: recording the physical location information of each virtual disk; and

[0031] Step 102: Allocate ...

Abstract

The invention discloses a method and device for partitioning discs into a host computer. The method comprises the following steps of: recording physical position information of each virtual disc; and distributing at least one virtual disc for the host computer according to the physical position information of each virtual disc. In the method and the device, the disc layout can be planned by using a simple method so as to balance the operation number of input and output (IO) of each physical disc and promote the data access performance.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method and device for dividing disks into hosts. Background technique [0002] At this stage, as a new storage medium, disk has gradually replaced paper storage medium as the main carrier of data storage. Using disks to store data can conveniently realize centralized storage and safe management of data. Generally, in order to allow the disk to better serve the host, the disk can be mounted on the host in the form of a Logical Unit Number (LUN, Logical Unit Number). figure 1 A storage structure is shown. Such as figure 1 As shown, the storage structure mainly includes a storage control unit and a physical disk for storage control. Wherein, the storage control unit provides two interfaces of a front-end port board (CHA) and a back-end port board (DKA). The CHA is used to connect at least one host, and the data exchange between each host and the disk is also completed through...
