Hot-swap Function
The DNS-346 supports hot-swap drive trays. You can eject or insert 3.5” SATA hard drive(s) when the DNS-346 is operating.
However, if the hard drives are created into various levels of RAID, you cannot hot swap all the hard drives at the same time. Hot swapping all the hard drives will cause a loss of
data, and the RAID volume will need to be re-created again. Different levels of RAID required various numbers of hard drives remaining in the DNS-346.
Standalone/JBOD/RAID O:
The data will be lost and the volume will crash, if any of the hard drives are hot swapped.
RAID 1:
You can hot swap the hard drives as long as one of the hard drives in the mirror is still in the DNS-346. Removal of all hard drives will result in a loss of all data and
volume will have crashed.
RAID 5:
In a RAID 5 volume, it is only possible to hot swap 1 hard drive at a time without losing all data. This is because a RAID 5 volume can only tolerate the loss of 1 hard
drive and still continue to work. After hot swapping a hard drive, the volume must first be rebuilt before another hard drive can be hot swapped, otherwise this will also
result in a loss of all data and the RAID volume will have crashed.
RAID 10:
RAID 10 is a stripe of mirrors. You cannot hot swap the paired hard drives at the same time. This means Hard Drive 1 and Hard Drive 2, or Hard Drive 3 and Hard Drive
4 cannot be hot swapped at the same time. Otherwise, you will lose all data and the RAID volume will have crashed.
You can check the RAID configuration from the Setup -> Disk Management page on the Web UI. When hot swapping hard drives, you will see the changes in the Disks column.
Hot swap one of the hard drives, make sure the Disk number has disappeared from the Disks column, and then hot swap the next hard drive.
Storing non-English Character Files
By default the DNS-346 will support Unicode which is an industry standard allowing computers to consistently represent and manipulate text expressed in most of the world’s
writing formats.
