Disk array Graphics tutorial, what is a disk array

　　The disk array (redundant Arrays of inexpensive disks,raid) has the meaning of "inexpensive and redundant disk arrays". the principle is to use array method to do disk group, with the design of data distributed arrangement, improve the security of data. The disk array is made up of many inexpensive, small, stable, slow disks, combined into a large disk group, and the added effect of providing data with individual disks increases the performance of the entire disk system. At the same time, the technology is used to cut data into many sections, which are stored on each hard disk. The disk array can also take advantage of the idea of the same bit check (Parity check), when any hard disk in the array fails, the data is still readable, and when the data is refactored, the data is calculated and then reset to the new hard drive.

Nothing to do, group a RAID 0, feel good, the speed has been significantly improved, load the game and start the program speed improved

Single disc speed chart below:

RAID0 speed diagram below:

The hard drive is this, two Seagate 500g single disc

　　Step method

1, the following said steps, because the board is not the same, enter and set the method is different, the following to my p55a-ud3r for example, the Intel board settings are basically the same:

First after the power is opened B I o s in the P O s T, press the <d e l e t e> key to enter the B I o s setup program. To make R A I D, enter

"integrated peripherals" the "pch SATA contrp mode" option to "raid (XHD), exit the BIOS program settings and save the settings results.

The following figure

2, and then you need to enter the RAID Setup program to set the following steps:

　　Step One:

After the BIOS post screen, before entering the operating system, there will be a screen like the following, press the <Ctrl>+<I> key to enter

The RAID Setup program.

Step Two:

The main screen of the P55 RAID Setup program appears when <Ctrl>+<I> is pressed.

Create a disk array (create RAID vpume)

Press <Enter> on the "create raid vpume" option to make a RAID disk.

Step Three:

Entering the "create vpume menu" screen, you can customize the name of the disk array in the "name" option, with the words most

The number can be 16 letters, but can not have special characters, set good after the <e N T E r> key. Select the R a I d mode to make (R a I D

Level). RAID mode options are: RAID 0, RAID 1, Recovery, RAID 10, and RAID 5 (selectable raid modes

Depends on the total number of hard drives installed. After you select good RAID mode, press <Enter> to continue with the steps that follow.

Step Four:

In the "d i s k s" option, select the hard drive to make the disk array. If only two hard drives are installed, the two hard drives will be automatically set to the disk array.

Next, select the disk window size (Strip size), which ranges from 4 KB to 128 KB. When the settings are complete, press <Enter> to set the disk array capacity (Capacity).

Step Five:

After setting the disk array capacity, press <e N T e r> to move to "c R e a t e Vo l u m e" (build disk) option. In "c r e a T E

Vo l u m e"Press the <e N T e r> key to start making the disk array. When the confirmation message appears, make sure that the disk array is made by

<y>, cancel please press <N>.

3, after the completion of the "disk/vpume information" can see the set up a good disk array details, such as disk array mode, window size, disk array name and disk array capacity, and so on, the following is my array information.

4, the final setup is completed in the main screen press <Esc> button or select "5. exit", and then press <Enter> to exit the RAID Setup program.

Press down to make the SATA RAID/AHCI driver floppy disk and install the operating system, after installing Intel's RAID program, you can view raid information and management,

Speed-seeking friends can open the write-back cache, but it may cause a sudden power outage when the hard drive data is not saved, I did not open.

Well, that's probably it .... Thank you for seeing this ....

5, another AMD method, take 770t-ud3p as an example, because the board with more people, I used to use this time ago, AMD settings are similar:

6, first in the power supply, the BIOS in the post, press the <Delete> key can enter the BIOS Setup main screen, and then enter

"Integrated peripherals" to confirm that "Onchip SATA Contrpler" is turned on.

Set the Onchip SATA type option to raid; set the Onchip SATA type to raid and Onchip

SATA PORT4/5 Type "is set to as SATA type."

7, and then enter the raid BIOS, set RAID mode:

The system starts after the BIOS post (power-on Self test post) screen, before entering the operating system, it appears as

Click the <Ctrl> + <F> key to enter the RAID BIOS Setup program as shown in the picture.

8. Press <Ctrl> + <F> key into the RAID Setup program-the Main menu window appears.

(main menus): Main Menu

If you want to view disk information in the disk array, press <1> to enter the view Drive Assignments screen.

If you are setting up a disk array, press <2> to enter the Define LD screen.

If you want to remove the disk array, press <3> to enter the delete LD screen.

If you would like to see the SATA control port configuration, press <4> to enter the "Contrpler Configuration" screen.

9. To establish a disk array, press <2> in the main menu to enter the Define LD window. This feature allows users to

Manually specify the hard disk to be used as the disk array and define the disk array mode, as required by the individual.

10. Use the up and down keys to move to a logical disk group and press the <Enter> key to enter the disk array Settings screen.

11, the following began to make RAID0:

1. Under the RAID mode item, press the <SPACE> key to select RAID 0.

2. Use the arrow keys to move to the "stripe block" item, and then press the <SPACE> key to switch to the desired chunk size. (Default value:

MB, recommended set to 128K)

3. Then under the "Drives Assignments" project, use the up and down keys to select disks to join the disk array.

4. Press the <SPACE> key or <Y> key on the selected disk "assignment" to switch to "Y". This operation will make the magnetic

Disk into the array of disks you want to make. Total DRV also displays the number of disks added to the array.

5. After the completion of the set, press <Ctrl> + <Y> key to save the set value will appear as shown in the picture.

6. Press <Ctrl> + <Y> key to select clear master boot record, or press other key to ignore this option. The following will appear as shown

The picture shown.

7. Press <Ctrl> + <Y> key to select a custom disk capacity, or press the other key to choose the maximum disk capacity.

8. After the completion of the production will return to the "Define LD Menu" screen. In this screen you can see the newly created disk array.

9. Press <Esc> key to return to main menu. To exit the raid BIOS Utipty, press the <Esc> key.

12. View disk status

The View drives Assignments window shows whether the disk connected to the AMD SB710 controller is designated as a disk array

Members. After entering this window, you will see the disk array to which they belong under the disk's assignment item.

If the disk does not establish a disk array, it appears as free.

13, the next can be SATA RAID/AHCI driver floppy disk production and installation of the operating system, after the installation of AMD driver and RAID management program, you can view the raid or Achi and NCQ settings management, the following figure:
