Rebuilding a High-Capacity SSD Array

When a 3.84TB drive fails, the rebuild takes longer than with smaller drives. During that time the array has reduced protection, particularly in RAID 5. Good practice includes:

• Replacing the failed drive as soon as possible
• Using RAID 6 for arrays of many large drives
• Monitoring rebuild progress in HPE Smart Storage Administrator
• Keeping a cold spare for critical servers

Controller Pairing

Gen10 servers commonly host large SATA SSD arrays on controllers such as the HPE 804338-B21 P816i-a, which supports RAID 6 and larger drive counts.
