Problems solved by technology

[0004] The traditional software implementation of the RAID system requires the support of the operating system. The RAID configuration information is stored in the system information instead of on the hard disk. However, when the system crashes and needs to be reinstalled, the RAID information will also be lost.

Abstract

The invention discloses a disk array controller set and relates to the technical field of disk arrays. The disk array controller set is characterized in that a first SATA disk (1), a second SATA disk (2), a third SATA disk (3) and a fourth SATA disk (4) are connected with a first SATA controller (5), a second SATA controller (6), a third SATA controller (7) and a fourth SATA controller (8) respectively; the first SATA controller (5), the second SATA controller (6), the third SATA controller (7) and the fourth SATA controller (8) are all connected with an input-output controller (9); the input-output controller (9) is connected with a disk array CPU (10); the disk array CPU (10) is connected with a DMA controller (11), a cache controller (12) and a storage controller (13). The disk array controller set is flexible and convenient to use and highly safe and reliable.

Description

technical field [0001] The invention relates to the technical field of disk arrays, in particular to a disk array controller. Background technique [0002] With the increasing popularity of computer applications, people's requirements for computer speed and performance are gradually increasing. In a complete computer system, CPU and memory are important, but the performance and speed of data storage devices also directly affect The performance of the entire system, and with the rapid increase in the amount of information, how to effectively and safely save and back up those valuable information becomes important. RAID is the abbreviation of Redundant Array of Inexpensive Disks. It distributes data on multiple disks in multiple channels, and uses parallel processing mechanism to coordinate multiple independent disks to achieve the purpose of improving storage speed and increasing storage capacity. In addition, disk arrays improve data security by increasing data redundancy. ...
