If one storage device is down between two storage devices, the Storage Cluster function fails over transparently to the other storage device.
Configuration and Management of Storage Cluster
Storage Cluster and its settings can be configured and checked through the Web Console.
There are two ways of failover to storage device as follows:
Automatic Failover
The life of storage devices is monitored and if any failure in one storage device, switchover to the other storage device is automatically done.
Manual Failover
Failover is directed and performed through the Web Console.
