4. Disk roaming allows arrays to be moved from port to port, either within the same system or between systems. 5. See the system’s motherboard specifications for the supported device interface. RC-8.1 and RC-8.2 branches support only SATA. RC-9.1 and above release branches support SATA, M.2 NVMe SSD and HHHL NVMe SSD 6. Multiple RAID levels (array types) per disk allows the administrator to create different RAID levels on the same disks. For example: The administrator wants data redundancy for the user data, and creates a RAID1 set using part of the disks’ data. At the same time the administrator wants performance for the swap spaces, and creates a RAID0 array using the rest of the disks’ capacities (space). This feature is useful in collecting unused capacity from disks with different capacities. This feature increases data integrity for redundant array types, by logging areas of an array that have been written to. In the event of a system crash, the logged area’s consistency is checked and/or corrected. Without this feature, data corruption might occur. 7. Arrays can be instantly created and used by skipping the background consistency check. For certain types of redundant arrays this is a viable option and has no data integrity drawbacks. A consistency check can always be done at a later time. If an initialization is skipped when creating a RAID1, the array is not redundant until a consistency check is performed. 8. It is not recommended to add a Disk to the system and to the array while the system is operating.
