3.5-inch Drive Model
Up to twelve 3.5-inch Drives
Up to twelve 3.5-inch Drives plus two 2.5-inch Drives
NOTE:
All hard drives within a RAID array should be of the same capacity and rotation speed. Also, hard
drives in the back side (slot 12 to 13) must be in a separate RAID array than RAID arrays of hard
drives in the front side (slot 0 to 11) for configuration 4.3.4 to 4.3.6.
Dedicated Hot Spare / Global Hot Spare are supported by using RAID controller card (PCI Express).
However, Global Hot Spare is not supported on the configuration 4.3.4 to 4.3.6. Also, hard drives in
the back side cannot be used as Hot Spare drives of a RAID array of hard drives in the front side and
front side drives cannot be used as Hot Spare drives of a RAID array of hard drives in the back side.
To configure a large-capacity RAID array, it is recommended to configure in RAID 6 or RAID 60 in
order to minimize the risk of becoming multiple hard drives failure during the RAID rebuilding process.
It is recommended to set RAID array configuration drives less than eight in order to minimize the risk
of becoming multiple hard drives failure.
