Product Manual Technology Background
The disk array’s data capacity is equal to the number of disk drive members multiplied by the
smallest drive’s capacity. For example, one 100 GB and three 120 GB drives form a 400 GB (4 x
100 GB) disk array instead of 460 GB.
If physical drives of different capacities are used, there is unused capacity on the larger drives.
RAID 0 logical drives on
Vess consist of one or more physical drives.
