Basic Configuration Rules
When you are configuring your S12S subsystems, the following are
some basic rules that should be followed.
NOTE:
Please adhere to these basic configuration rules. They are
provided for your convenience to ensure that your storage system
will run smoothly and effectively.
When cabling, pay attention to signal quality and avoid electronic
noise from adjacent interfaces.
A spare drive should have a capacity equal or larger than the
largest drive that it is expected to replace. If the capacity of the
spare is smaller than the capacity of the drive it is expected to
replace, then the controller will not proceed with the failed drive
rebuild.
Enclosure ID:
There is a rotary ID switch on every expansion enclosure that is
manually configured using a flat blade screwdriver. The
enclosure ID on JBODs starts from 1 to 4, (usually the numbering
starts from one closest to the managing RAID enclosure).
The dual-controller S12S-R1032 connects to a maximum of
3
JBODs.
The single-controller S12S-G1032 connects to a maximum of
4
JBODs.
Make sure a unique ID is assigned to each JBOD so that the disk
drives can be properly addressed.
