Problems with adding hard disks to the array, questions about disk arrays

What is a RAID Disk Array? How does it work? What is the difference between raid0 1 10? Let's have a good chat today!

When the disk is arrayed, the array card is also known as the read card, and the array card array mode has two read0 and read1

To do a disk array, an array card cable is required.

Let's see how to make it work.

Insert the array card into the PCI slot, and use the correct data cable to connect the disk to the display card. Start the machine, after the self-test, characters such as press control+f will appear on the screen, then press control + f to enter the disk array interface.

The first item is (auto setup......We're going to enter the array here, use the arrow keys to select the array mode, if you don't understand English, when you choose a certain mode, observe that the disk usage space will change, all of them will increase or decrease exponentially, and you can judge which mode we are using, but it is not accurate. Here I choose string (which is the reda0 mode) to save and exit. Prompt with control + y when confirming

Once you are in the system, open Device Manager and you will see the Read SCSI ......and so on literally and install it in the same way as installing new hardware.

Right-click on "My Computer" and select "Management" "Disk Manager", and you will see that there is a large capacity below the local disk and the status is Unassigned. Format it first, select the file system, right-click "New Partition" and follow the prompts. It can be managed as a disk by assigning a drive letter.

It can also be managed as a volume in a disk and as a folder. If the file system is NTFS, pay attention to the permission changes and settings.

1. Add 1 disk to RAID0, RAID0 should be rebuilt, and the data will be lost.

2. If you can't do this, you don't know what you want to achieve, you can do 2 raid0s, or find 4 disks with the same disk to do 1 raid0

3. In general, the more disks in RAID0, the faster the speed. However, array controllers will have a limit on the number of RAID disks.

Redundant arrays of inexpensive disks (RAID) means "cheap and redundant disks". The principle is to use the array method as a disk group, and cooperate with the design of data scattered arrangement to improve data security. A disk array is composed of a large number of cheap, small-capacity, high-stability, and slower disks combined into a large disk group, and the add-on effect generated by the data provided by individual disks improves the performance of the entire disk system.

At the same time, using this technology, the data is cut into many segments, which are stored on each hard disk. The array also uses the concept of parity check, which can still read out data if any hard drive in the array fails, and when the data is reconstructed, the data is calculated and re-placed into the new drive.

For more information, please see. Disk arrays are easy to store, and have nothing to do with improving system performance.

The disk array has at least two hard disks, and you need to install the array driver before you can install the system!

To put it simply, lest you don't understand, it is a few hard disks connected to the motherboard, you should have seen it, and there is a RAID card on the board, and the general server on the PCI is only used to do it, and after the array, the hard disk will read data 50MB s faster than the general hard disk

What RAID 0 is that it must be composed of two identical hard disks, that is, two hard disks into one hard disk and then use.

What is RAID0+1 RAID1 RAID5 etc., how is it composed, what are the functions, you can check the information on the Internet.

That's how fast the hard drive is! Use it as a hard drive in your system!

It's easy to understand, you can take two hard disks and try RAID 0 yourself!

To put it simply, combine two disks into one disk, and double the read speed and capacity.

Generally, this requires the support of the motherboard.
