A guideline of expanding time is shown in the following table.
Table 4-19 Guideline of initialization
RAID level Capacity of a disk array Rebuilding time for expansion
RAID 0 900GB (SAS: 300GB HDD x 3) Approximately 210 minutes
600GB (SAS: 200GB SSD x 3) Approximately 70 minutes
RAID 5 600GB (SAS: 300GB HDD x 3) Approximately 160 minutes
400GB (SAS: 200GB SSD x 3) Approximately 60 minutes
RAID 6 600GB (SAS: 300GB HDD x 4) Approximately 170 minutes
400GB (SAS: 200GB SSD x 4)" Approximately 60 minutes
Tip: The rebuilding time for expansion is proportional to the capacity of a
disk array regardless of the number of hard disks to add.
