Instructions
On Dynamic Pool creation wizard, there is a minimum number of drives that need to be selected to create the Pool. This number directly depends on the RAID type selected, and a warning will be provided if the minimum drive count is not satisfied. The table below shows the relationship between the RAID type, the RAID width, and the minimum number of drives to create the Pool. This table only shows the smallest RAID widths supported, and the minimum number of drives it takes to create them. As an example, the smallest RAID 5 RAID width the system supports is a 4+1. The smallest Dynamic Pool created with the RAID 5 4+1 configuration is 6 drives. The minimum drive count includes the number of drives specified in the RAID width, plus an extra drive to satisfy the spare space requirements.
