| *1 | : | Use of RAID0 is not recommended because it is not redundant. For RAID0 configurations, data may be lost due to the failure of a single drive. |
| *2 | : | Fujitsu original RAID level that provides the high speed rebuild function, and striping with double distributed parity. |
| *3 | : | The maximum number of RAID groups that can be registered (for the RAID1 configuration). |
| *4 | : | The maximum number of volumes that can be created in a TPP is calculated by subtracting the number of RAID groups that configure the relevant TPP from the maximum number of volumes that can be created in the ETERNUS DX. |
