Wanquan R630 Server assembled RAID5 array

Essay

Yesterday the leader let me to a server to do the system, itself as development I have some challenges. And what the leader says, how do you try to do it?

In the afternoon to the computer room to find the server was just to install a system to finish, and I understand the server itself has a system, thought to take the system disk put into the dual-machine installation is, the leader said to do raid, asked me to do which version, fortunately I checked the information on the system in the morning, the original colleagues mentioned RAID5, Check the following information in the morning, when the leader said without hesitation said to do raid5~ actually I do not know how to do, mainly do not know why choose RAID5

Talk about your special situation, itself because the Bois does not turn off the authentication of the PXE, causing the Mac ADDRESS and the DHAP dynamic IP prompt when booting, must be manually operated to enter the system.

It is not clear whether it is for this reason, the system can not pop up the self-test information, so also can not enter into the Ctrl+h Webbois, then still do not know how to be good,

The SATA MODE in Bois has been incorrectly changed from IDE to SW RAID (all RAID-related configurations are selected).

The result is that the hard drive is not found when you start

Very depressed, and I also mistakenly hot-swappable two hard drives, because when I select the IDE in the stat MODE is the following ports 1 [Ports2 are not installed I think is the problem of hard disk, so hot Plug and unplug two hard disk ... Once again plugged in when the hard drive lights turned red, then frightened, thinking that they have broken the hard drive ~ ~ ~, really blind cat met dead rats, of which two hot-swappable hard drives have a system disk ... Then the remaining five in the re-boot when the system is not found, there is no pop-up MAC address and other information, a direct pop-up hint ctrl+h into the Webois, almost gave up the Buddha and found a solution, and this setup method can be found on the Internet. Very happy to start the happy set raid ...

Clear Configuration---- New configuration-- Manual Configuration. And so on, the default system starts from the CD-ROM when it is set up, and the system disk that is placed in the long Windows Server R2 begins to work, and when the system is installed, everything is over. The results told the leadership after the leadership said it should be 7 hard drives, the other two will certainly be able to use ... Helpless, re-do ..... But there is a little bit of confidence.

itself has been conceived, re-clear the configuration and so on. The facts are not so satisfying ...

Add two hard drives (bright red) in the I set to Clear configuration----new configuration--Manual configuration: Selecting to group is not selectable because the status is unconfiguration good: Helpless, began to think, check the information of the steps. Online post describes the need to set the Properties property, set and then set to make GLOBAL HSP prompt exception, unable to set

Later found that the data is required import rules, helpless, in the re-acquisition of hard disk status when it does prompt, import rules All import failed, helpless under try clear key results found clear after unexpectedly good ... Bois the original two red light of the hard drive turned green. Everything... Continue the leading edge. Continue to Webbois setup and finally get it done ... Hereby RECORD:

RAID Introduction--excerpt from huaqing Huaqing teaches you to assemble RAID5 and RAID1 server technology application _ pacific Internet Pconline

With Huaqing Plain English said, the so-called RAID0 is two hard disk to synthesize a hard disk, for example, two 80G hard disk, made RAID0 mode, become a large 160G hard disk, theoretically hard drive transmission speed is doubled, but this mode security is very low, once a hard drive is broken, All data in two hard drives is reimbursed, so it is best not to use this mode on the server.

The so-called RAID1 is two hard disks to do each other synchronous backup (mirroring), such as two 80G hard disk, made RAID1 mode, the total capacity or 80G unchanged, hard drive transmission speed has not changed, but two hard disk data kept in sync, exactly the same, once one of the hard drive is broken, by another hard drive, The server is still working properly, this mode is very safe, so now a lot of low-end servers to take this RAID mode, this mode is simple and practical, with low hardware costs can be achieved, I like. As for RAID5, the past has been the patent of high-end servers, even today, you turn over many brand-name server price list, in the 120,000-yuan product is also difficult to find RAID5 figure, the use of RAID5 can take into account raid0 speed, capacity and RAID1 security, It's a perfectly sound disk array solution.

Capacity: free space = number of disks n-1, one of which is specifically used to verify, when storing data, the check disk is not stored in the data) (Raid 5 does not have a separate parity disk, all the calibration information scattered on all disks, just in storage space for N-1)

Note:RAID 5 RAID 5 arrays must have the same capacity for all disks, and when the capacity is not the same, the minimum capacity will prevail. The best hard disk speed, otherwise it will affect performance, and free space = number of disks n-1, one of which is specifically used to verify, when the data is stored, the check disk will not be deposited data) (Raid 5 does not have a separate parity disk, all the calibration information scattered on all disks, Just N-1 on the storage space)

System in operation is to use Ctrl+h to enter the Webbois settings, if all the disks are normal state, does not exist because hot plug causes the hard drive light to turn red words can be added to the workgroup and then accept the last save

Operation Steps:

RAID5 configuration settings detailed plots:

The first step, an all-in-one drive, restarts the computer to the Boot interface ( You can see three virtual disks ) such as:

The second step, by the interface prompt: Output ctrl+h key combination into the RAID card webbios Management Interface

Check "Start" to enter the RAID card management configuration interface such as :

Step three, press tab to move the cursor to the Configuration Interface option and enter the Configuration Management wizard and click "Next" as:

Press the tab key to move the cursor to select the first ' clear Configuration ' to clear the previous old RAID card configuration as

Click "Yes" to confirm. Select the second option "new configuration" and click "Next" as

Click "Yes" to enter the RAID settings to proceed to the next step.

Select the first item "Manual Configuration" as

Click "Next" to set up the next steps such as:

Select the hard disk to which you want to join the virtual Disk group, and then click "Add to Array" and add it to the corresponding list of the right virtual disks .

Click "Accept DG" after adding the hard drive ( You can continue to add multiple sets of virtual disks, similar to this operation )

After allocating the hard disk and creating the Virtual Disk group, click "next" to set up the next

After the RAID level parameter option appears on the left , Click "Add toSPAN" for adding the logical disk to the right list box ( Add a raid Virtual disk group at a time, such as:

Click "next" to proceed to the next step, with the RAID attribute parameter settings such as:

After setting the appropriate parameters such as (note the parameter settings):

After you click "Accept" after setting up, thelist bar appears to add the virtual disk as:

If you need to add more virtual disks to configure, click "Back" to return, as shown in:

This step is selected with the previous operation : drive group:1 ,drivegroup:2 ..... (Note that you can only and configure one virtual disk group at a time ; back to the first virtual disk operation) after adding the configuration, click "Next" Next Step

For example, click on the "Accept" pop-up interface as follows:

Click "Yes" To confirm the save configuration , and the popup interface prompts you to initialize the RAID as follows:

Click "Yes" to confirm RAID initialization ( Note: The configuration saves several raid The group pops up a few times on this tip screen ).

and jump to the initialization mode selection interface such as:

and select "Slow Initialize" (Fast initialization and automatic in the background) click "go" to start the initialization ( usually start in a few minutes or so ) Also pop-up interface prompts such as:

Click "Yes"to confirm the start of initialization. Automatically jump back to the interface as follows:( the initialization progress bar must be initialized before you can restart the computer )

Click "Home" to return to the main interface, choose to exit the restart system (or press Ctrl+alt+del to restart directly)
