RAID 0
Q:
If I have 4 HDDs, can I create two sets of storage units by using RAID 0
mode?
A:
The RS-M4QO is designed to support 4 HDDs, but it cannot create or support
two sets of storage units under the RAID 0 mode.
RAID 1
Q:
If I inserted 4 HDDs into the RAID System to do RAID 1, and have already set
the HD Switch to 4 HDDs, why are only HDD 1 and HDD 2 LED lights staying
white?
A:
The RS-M4QO can only process two HDDs under the RAID 1 (Mirroring)
mode, under HDD 1 and HDD 2 slots only if all 4 HDDs are inserted. Based on
the chipset, it is not possible to process two sets of HDDs at the same time.
RAID 5
Q:
If I have inserted 4 HDDs, set the RAID Switch at RAID 5, but have the HD
Switch set at 3 HDDs. Will this work?
A:
Yes, you may do so, but the RAID System will automatically reset the RAID
mode to RAID 5+HotSpare. The RAID System is created to determine first on
the number of HDDs inserted into the System, then the RAID mode setting.
Occasionally, the System will still reflect a “healthy” status even though the
number of HDDs inserted is not the same as the HD Switch setting.
RAID 5 + HotSpare
Q:
Why is the HDD 1 LED light off when the RAID System is operating under the
RAID 5+HotSpare mode?
A:
Due to the chipset design, the System is created to recognize HDD slot no. 1
as the backup HDD. Therefore, when one of the HDDs fails, the backup HDD in
slot no. 1 will automatically start to rebuild to replace the failed disk.
