SCSI, CERC SATA, And CERC ATA RAID Controllers

When using a SCSI, CERC SATA, or CERC ATA RAID controller, the controller calculates the maximum virtual disk size based on your RAID level selection and the available physical disk space provided by all suitable physical disks attached to the controller. For example, if the controller contains 12 physical disks with available space and you have specified a RAID 5, then the controller calculates the maximum virtual disk size based on the disk space provided by the 12 physical disks, because the 12 physical disks can be included in a RAID 5.
