When it comes to hardware RAID, a reliable and robust storage system is the goal. However, what happens if the motherboard or controller fails?
The answer depends on the type of RAID system. In a RAID 1 system, the data is mirrored across two disks, so if the motherboard or controller fails, the data is still available. However, the system will have to be rebuilt, which means that the disks must be installed into a new motherboard or controller and then configured again.
In a RAID 5 system, the data is spread across multiple disks and protected by parity. If the motherboard or controller fails, the data is still available, but the system must be rebuilt like in a RAID 1 system.
In a RAID 6 system, the data is protected by two sets of parity. This provides extra protection, but if the motherboard or controller fails, the data is still available. However, the system must be rebuilt like in a RAID 1 and RAID 5 system.
In a RAID 10 system, the data is mirrored across two disks and spread across multiple disks. If the motherboard or controller fails, the data is still available, but the system must be rebuilt like in a RAID 1, RAID 5, and RAID 6 system.
In short, if the motherboard or controller fails in a hardware RAID system, the data is still available. However, the system must be rebuilt, which involves installing the disks into a new motherboard or controller and then reconfiguring the RAID system. This can be a time consuming and potentially costly process, so it’s important to ensure that your RAID system is properly backed up. This will enable you to quickly and easily restore the system in the event of a motherboard or controller failure.
