M-Series can use a mix of 3.5” and 2.5” disk enclosures at the same time.
M300 supports up to 144 disk drives and up to 7 disk enclosures. Note that even if a disk drive slot is
not populated, it is still counted. (M300 supports up to 144 disk drive slots.)
<Example 1> M300: The total number of disk enclosures exceeds the maximum supported
number of disk enclosures
Model number Product name Cable length Remarks
NF9120-SJ54 SAS Cable （5m） 5m
2 x SAS cables (DAC-DE / DE-DE)

When the base unit and one or more disk enclosures will be in different racks, a SAS cable (1m) will
not be long enough, necessitating the SAS cable (5m) in the table below.
6 x 3.5” Disk enclosures
2 x 2.5” Disk enclosures
This configuration has 8 disk enclosures

M300 supports up to 144 disk drives. I’d like to configure M300 with 132 disk drives.
1 x 3.5” DAC + 6 x 3.5” DEs + 2 x 2.5” DEs
12 disk drive slots in DAC＋72 disk drive slots in 3.5” DEs ＋ 48 disk drive slots in
2.5” DEs = 12 ＋ 72 ＋ 48 = 132 disk drive slots. All slots are populated.
