RE: Upgrade T110 II Hard Drive space
The S100 software RAID controller does not support 4 TB hard drives' capacity. The most viable option is to upgrade to the hardware based RAID controller H200 which has support for drives of greater than 2 TB capacity. However, migration of Virtual Disks from software base controllers to hardware based controller e.g; S300 -> H200 is not supported. Therefore, to upgrade to H200 controller, if considered; you will need to backup your data and recreate another VD on the new controller with existing drives.
