Use soft RAID-1 on FreeBSD

Have you ever thought of making soft RAID for low-end servers? You may have thought about the redundancy of your workstation with disk mirroring without purchasing a hard RAID control card. Have you ever had painful configuration experiences that deterred you from soft RAID on Unix systems? The FreeBSD 5.3 and higher versions are added to Gmirror (8); it lets yo

Disk management-RAID 1

1. What is RAID1? RAID1, which can be called an image, writes data to multiple disks. For example, if A group of data is called A, data exists like this: A and A. In this way, data security is high, but performance is poor. Two or more groups of N disks are used as images for each other. In some multi-threaded operating systems, the read speed is good, and the write speed is slightly reduced. Unless the primary disk and image with the same data are d

System Disk categoryIn Windows 2000 Server, disks are classified into basic disks and dynamic disks.Basic disks comply with the partition-oriented solution in the disk organizational structure of Windows NT Server 4.0. When you install the Windows 2000 Server operating system, the system automatically initializes the physical disk as a basic disk. You can create and delete primary partitions, extended partitions, and logical partitions on a basic disk. You cannot create disk images.A Dynamic Dis
