The Mechanism
Managing a RAID 60 array requires an extraordinary amount of computational power. The hardware RAID controller card must simultaneously manage block-level striping across multiple groups while constantly processing complex dual-parity calculations. Because of this workload, RAID controller processors run incredibly hot and rely heavily on internal NVRAM and fast cache memory.
The Impact on RAID 60
If the controller's cooling fan fails or the card suffers an electrical surge, the hardware can burn out entirely. Furthermore, a sudden power failure can cause a "Write Hole." If the system loses power precisely while writing data to the disks but before the corresponding dual-parity blocks can be written to the drives, the parity math becomes desynchronized.
Without a functioning Flash-Backed Write Cache (FBWC) or a healthy Battery Backup Unit (BBU) to preserve and flush that cached data safely once power is restored, the entire RAID 60 metadata structure can become corrupted, making all drives appear unformatted.
