This step-by-step article describes how to mirror the system and boot partition in Windows Server This scenario is based on the assumption that the system and boot files are located on disk 0 and that disk 1 is unallocated space. The memory dump file is written only to the boot hard disk.

Windows Server can continue to work with a mirrored system disk configuration even if one of the disks in the mirror is removed. However, the memory dump file cannot be written to the remaining system disk in the mirror. You must schedule a system restart for the memory dump file to be written to the remaining hard disk.

On the View menu, point to Top, and then click Disk List. In the right pane, the attributes of each disk in the system are displayed. At the bottom of the right pane, a color-coded graphical view of the disks on the system is displayed:. Any disks that you are upgrading must contain at least 1 megabyte MB of free space at the end of the disk for the upgrade to succeed.

Disk Management automatically reserves this free space when it creates partitions or volumes on a disk, but disks with partitions or volumes that are created by other operating systems may not have this free space available. You must be logged on as an administrator or a member of the Administrators group to complete this procedure.

If your computer is connected to a network, network policy settings may also prevent you from completing this procedure. A dialog box opens in which any disk on your system that is available for mirroring is displayed.

One stores the data which is being used, and another keeps a copy of the previous one. If your disks not dynamic, please see "Regarding Basic Disk convert to Dynamic Disk" for more information. To set up software RAID, do as following:. Open Server Disk Management.

Right-click one of the volumes on the dynamic disk and select the "Add Mirror". In software RAID 1, due to some reasons, you may need to convert dynamic disk back to basic disk.

To convert dynamic disk back to basic in Server Disk Manager, you have to delete all existing partitions before conversion. A software RAID 5 requires three disks at least; it not only can enhance the efficiency of the disk but also provide the best fault-tolerant.

A RAID 5 is a fault-tolerant volume in which the data is striped across an array of three or more disks. Parity a calculated value that can be used to reconstruct data after a failure is also striped across the disk array.

If a physical disk fails, the portion of the RAID 5 that was on that failed disk can be recreated from the remaining data and the parity. At least 3 disk will be required. About software RAID RAID is a technology that allows a volume partition uses together with the space on the multiple disks, in this way, disk's utilization and system performance can be improved.

How to set up s oftware RAID 1 step by step? To set up software RAID, do as following: 1. Then, open a window. Please tick another dynamic disk, and click "Add Mirror" button: 3. After completing, you will see the following screen.
