Microsoft Windows Server 2012 provided RAID solution:
Installing Microsoft Windows Server 2012 utilizing the on-board SATA controller doesn’t provide data redundancy. In the event you want data redundancy, you can use the software raid functionality provided by the Microsoft Windows Server 2012 operating system.
- Go to disk management.
- Right click on the disks and convert it to dynamic disk.
- Right click on the volume for which you want redundancy and create “Mirrored Volume” or “RAID-5 volume”
Note: Redundancy can be provided for both data and operating system volume but the latter supports only “Mirrored Volume”. For more information about using operating system raid solution refer to Microsoft documents
