What type of RAID configuration is used primarily to ensure data redundancy in PowerEdge servers?

The primary focus of RAID 1 is to ensure data redundancy through mirroring. In a RAID 1 configuration, data is duplicated across two or more disks, so if one disk fails, the other disk(s) still contain a complete copy of the data. This setup provides a reliable safeguard against data loss due to hardware failure and allows for continued access to information even in the event of a drive malfunction.

RAID 1 is particularly beneficial in environments where data integrity is critical, as it allows for quick recovery of information without any loss. In contrast, while other RAID configurations like RAID 5 and RAID 10 also provide redundancy, they do so in different ways that may involve more complex setups or a mix of performance and redundancy, but RAID 1 maintains a straightforward approach that focuses entirely on ensuring that data remains available through duplication.
