Disk drive structure
◗
There are four methods to configure disk drive structure. Select
preferred method.
Normal mode
Select this mode to use four 250GB hard drives individually.
Spanning mode
Select this mode to combine four 250GB hard drives as a one 1TB
hard drive.
Mirroring Mode RAID 1 (250GB×2)
Two pairs are created from the 4 drives as two separate 250 GB
shares. Data stored on each pair is mirrored automatically to the drive it
is paired with. Therefore, should a single drive fail, data is not lost as it
is also located on the mirrored drive of the pair. Drive replacement and
rebuilding of the Mirror should occur as soon as possible though. After
setting this mode, file transfer speed becomes slow down temporarily
flashing DIAG lamp.
RAID5 mode
Select this mode to combine three 250GB hard drives as one 750GB
hard drive. Other hard drive is used to store parity check data. When
one drive is damaged, other drives supports damaged drive until
replacing damaged hard drive. After setting this mode, file transfer
speed becomes slow down temporarily flashing DIAG lamp.
Caution:If you change the hard drive structure, the system formats
all the drives. Please backup stored data in the hard drives before
changing the hard drive structure.
