High-performance storage pool organization method and device

Abstract

The invention discloses a high-performance storage pool organization method and device. The method includes the steps that an SSD, an SAS disk and an SATA disk are converted into a first RAID5 disk, a second RAID5 disk and a third RAID5 disk respectively through an RAID5 distributed odd-even check strategy; the three RAID5 disks are organized into a layered storage pool; storage spaces with the same capacity are obtained from three storage layers of the storage pool respectively and organized into a logical volume with three layers; all data needing to be read and written are written into the high-performance storage layer of the logical volume, and the access popularity of the data is calculated; if the access popularity of the data is smaller than a first popularity hreshold value and larger than a second hot degree threshold value, the data are migrated to the intermediate-performance storage layer of the logical volume. According to the method, on the basis of guaranteeing the large capacity of the storage pool, the read-write speed of the data is increased, and the safety of the data is improved.

Description

technical field [0001] The invention relates to the technical field of storage pools, in particular to a high-performance storage pool organization method and device. Background technique [0002] At present, in the era of rapid development of modern information, the data information is getting larger and larger, the requirements for information processing speed are getting higher and higher, and the requirements for data security are also getting higher and higher. In a traditional storage system, the back-end storage resources are based on one type of hard disk, such as SSD type hard disk, SAS hard disk or SATA hard disk. Only one type of hard disk is used in the storage pool, so the processing speed of information is reduced. Depends on the processing speed of this hard drive. [0003] Generally, if the storage pool uses SSD hard disks, the performance of the SSD hard disk itself is very good, but the capacity is small and expensive. Although the performance of the stora...

Problems solved by technology

[0003] Generally, if the storage pool uses SSD hard disks, the performance of the SSD hard disk itself is very good, but the capacity is small and expensive. Although the performance of the storage pool is good and the read and write speed is fast, the storage capacity is too low and the cost is too high. If the storage pool SAS hard disks or SATA hard disks are used. SAS hard disks have large capacity and low cost, but SAS hard disks have low performance. SATA hard disks also have large capacity and low cost, but SATA hard disks have lower performance, which will lead to storage pool costs. Low, large storage capacity, but the performance of the storage pool will be reduced, and the read and write speed will be slow

[0004] Moreover, the performance of storing data in the storage pool depends on a single storage medium, which has low performance, and verification affects the read and write requirements of the data. Moreover, SSD hard disks, SAS hard disks, or SATA hard disks are used, so the data on the hard disk is prone to data loss. In this case, the security of the data cannot be guaranteed, so the security of the data in the storage pool is very low
