Recently, the server encountered a small problem. I had to redo raid. I found an article on the Internet. I felt very careful. I 'd like to share it with you. Record the record when the server is reinstalled and share it with you. Hardware RAID 5: Recently, I personally assembled a 1u rack-mounted storage server with an 8-hard drive using a dual-core P4 820d processor. During the assembly process, I create

The full name of the disk array is: Redundant Arrays of Inexpensive Disks, raid, which roughly means a cheap redundant disk array. Raid can use a technology (software or hardware) to integrate multiple smaller disks into a larger disk device. This larger disk not only expands the storage space, data protection is also

So how can we solve the bottleneck of hard disk access speed? Creating a raid array with multiple hard disks is a better solution. However, due to the lack of practical experience, many network administrators only have vague concepts about RAID technology, we will share with you the basic raid knowledge and the most co

What is RAID (redundant Arrays of independent disks,raid, disk array)?The disk array is made up of many inexpensive disks, combined into a large disk group, which uses individual disks to provide data with the added effect to improve the performance of the entire disk system. Using this technique, the data is cut into
