【CAUTION: The Number of Disk Enclosures】
M-Series can use a mix of 3.5" and 2.5" disk enclosures at the same time.
The sum of available disk drive slots in both base unit and disk enclosures must not exceed the
supported maximum number of disk drives. Note: Even if a disk drive slot is blank, it is still counted.
For example:
I would like to use 120 disk drives in base unit (3.5") and four disk enclosures (2.5").
1 x 3.5" base unit: 12 disk drives in base unit
5 x 2.5" disk enclosures: 24 disk drives in four disk enclosures. 12 disk drives in
one disk enclosure.
Is this supported?

M110 Disk Array supports disk drives up to 120. However,
the sum of available disk drive slots in base unit and disk

of disk drives (120).
