And even more benefits of Silent Bricks!

Consistent safety when expanded with Silent Bricks: this advantage was mentioned several times in our conversations with customers in person and at the IBC trade fair. Fair is fair: not everyone is aware of this benefit, but it turns out to be of great importance. Suppose you own a RAID system, a standard storage system that you can expand simply by adding hard drives. Such a system is generally configured to allow two hard drives to fail without losing data. A RAID6 array thus has a redundancy of two hard disks, regardless of how many hard disks in total are connected in the array . Some users create a mirrored RAID6 for extra security, with twice as many hard drives, four of which are then allowed to fail. In such a system, if a hard disk fails, the system notices it and automatically grabs one of the spare disks. An excellent solution, unless another second and third hard disk fail before the first failed disk is completely “rebuilt.

Safety declines

If the storage needs grow, with a RAID you can simply install additional hard drives and expand the array. But the redundancy remains the same: two hard drives may fail. And then it doesn’t matter if the array includes 10 or 100 hard drives – two may fail. It is abundantly clear that with increasing numbers of hard drives, the probability of more than two hard drives failing increases – and so does the risk of data loss. By extension, the system is becoming increasingly unsafe. You can avoid this only if you add not hard disks but complete new RAID arrays with their own redundancy before the expansion.

Add redundancy

With Silent Bricks, however, the system remains equally secure with each addition of a new brick. In fact, each brick with its 12 hard disks already has that redundancy, whether dual, triple or quadruple, in it. Thus, the percentage security always remains the same; in fact, the overall system redundancy increases with each brick. A point that really struck us in the conversations!
