Normal Mode (Single) - AMS Venus T5 mini DS-2250J User Manual

Model: DS-2250J
XOR engine in the Raid Enclosure generates parity block. In RAID 3 mode, Parity Block will be
stored in the same hard drive. While in RAID 5 mode, Parity Block will be spread over all of the
different hard drives.
The Raid Enclosure will also make use of same size disk space in each hard disk under RAID 3(or
RAID 5) condition. (In RAID 3 or 5 modes, failure in a hard disk will cause the RAID Enclosure to
enter degraded-mode. Host controller still could read/write data through the Raid Enclosure
normally without knowing any defects. Users have to replace the defective hard disk. The Raid
Enclosure then will enter identical-rebuild mode automatically.)
2.7 Normal Mode
(Single)
Normal mode means all of the configured hard drives exist and the Raid Enclosure is not in
rebuild condition. Users can see the original hard drives from the host which supports port
multiplier technology.
(Note: If the host controller does not support Port Multiplier function, only one hard drive
on the operating system will be detected. The RAID tool is useful in this case.)
