Embodiment Construction

[0068] figure 1 It is a flowchart of an embodiment of the data arrangement processing method of the present invention, such as figure 1 As shown, the method of the present embodiment includes:

[0069] Step 101 , monitor each created LUN, and obtain current performance attribute information of each LUN.

[0070] Step 102 , for each LUN, from the current performance attribute information of the LUN, obtain the current performance attribute value that is the same as the performance attribute in the target performance attribute values ​​configured by the user corresponding to the LUN.

[0071] Step 103, when the current performance attribute value is not equal to the user-configured target performance attribute value corresponding to the LUN, according to the current performance attribute information of each LUN, obtain the average IO access data volume of each LUN.

[0072] In this embodiment, the current performance attribute information includes: number of write IOs, read IO...

Abstract

The present invention provides a data arrangement and processing method, device and server. The method includes obtaining the current performance attribute information of each LUN; The current performance attribute value with the same performance attribute value as the target performance attribute value; when the current performance attribute value is not equal to the target performance attribute value, obtain the average IO access data volume of each LUN according to the current performance attribute information of each LUN; and Obtain the average read IO latency and average write IO latency of each LUN; then perform data processing on each LUN based on the obtained disk access IOPS and disk access bandwidth of each LUN and the number of disk resources occupied by each LUN. The distribution process is performed so that for each LUN after distribution, the current performance attribute value of the LUN is equal to the target performance attribute value of the LUN.

Description

technical field [0001] The present invention relates to storage technology, in particular to a method, device and server for arranging and processing data. Background technique [0002] In the field of storage technology, for large-capacity data storage, a Redundant Array of Inexpensive Disks (Redundant Arrays of Inexpensive Disks; RAID for short) technology is used. The RAID technology encapsulates the underlying real disk into a logical unit number (Logical Unit Number; LUN for short). When data is stored, the LUN is divided into multiple sub-areas, and the data stored in the LUN is stored separately in the multiple sub-areas, where each sub-area becomes a partition. A partition table is used to record the location and capacity of the underlying actual disk corresponding to each partition. When reading and writing data, it is necessary to find the corresponding location of the underlying actual disk according to the guidance of the partition table, and perform data readi...
