Problems solved by technology

The disadvantage of this RAID implementation method is that the test of the RAID function inevitably involves the compilation and burning of the BIOS, which is tedious and time-consuming.
In addition, the operation of the RAID Option ROM may be interfered by other parts of the BIOS. If a problem occurs during the operation, it is not conducive to locating the cause of the error.

Embodiment Construction

[0012] refer to figure 1 Shown is an operating environment diagram of a preferred embodiment of the redundant array of independent disks (RAID) implementation and testing method of the present invention. This RAID implementation method is applied to the computer 100 . The computer 100 includes a processor 10 and a south bridge chip 20 mounted on a motherboard. The south bridge chip 20 is installed with a hard disk controller 21 and a universal serial bus (universal serial bus, USB) controller 22 . Wherein, the hard disk controller 21 is connected to the optical drive 30 and one or more hard disks, such as figure 1 Hard disks 40 and 50 in. The USB controller 22 is connected with a U disk 60 . The U disk 60 stores a RAID Option ROM program 61 for driving the hard disk controller 21 and providing a RAID configuration interface.

[0013] In this embodiment, the hard disk controller 21 is a serial advanced technology attachment (SATA) controller, and the hard disks 40 and 50 a...

Abstract

The invention provides a method for realizing and testing a redundant array of independent disks (RAID). In the method, an RAID Option ROM (Read Only Memory) is independently operated in an environment provided by a DOS (Disk Operating System), and the RAID Option ROM is not required to be contained in BIOS (Basic Input Output System) Firmware, so that the time for setting up the BIOS Firmware can be reduced, and the RAID Option ROM is prevented from being interfered by other parts of a BIOS during the process of operating the RAID Option ROM. Furthermore, in the DOS environment, after a logic disk of the RAID is successfully set up, the functions of the logic disk of the RAID can be immediately verified through setting the logic disk of the RAID as a startup disk of an operating system.

Description

technical field [0001] The invention relates to an implementation and testing method of a redundant array of independent disks (RAID). Background technique [0002] A redundant array of independent disks (RAID) is a redundant array composed of multiple hard disks. The multiple hard disks combined by RAID are used as an independent large-scale storage device under the operating system. The benefits of using RAID technology in the storage system are mainly as follows: First, by organizing multiple hard disks together as a logical volume, it can provide Hard disk spanning function; second, by dividing data into multiple data blocks (Block) and writing / reading multiple hard disks in parallel, the speed of accessing hard disks can be improved; third, providing fault tolerance through mirroring or verification operations. [0003] At present, many computer motherboards integrate the RAID implementation function. Usually, the onboard RAID implementation function is realized under...
