2. M300 Component Selection (13)
<Example 2> M300:The sum of disk drive slots exceeds the maximum supported disk drives 144.
M300 supports up to 144 disk drives and up to 7 disk enclosures. I’d like to
configure M300 with 144 disk drives and 7 disk enclosures as follow.
1 x 3.5” DAC (12) + 2 x 3.5” disk enclosures (2 x 24) +
5 x 2.5” DE: 4 DEs are full of disks (4 x 24). One DE is half full (1 x 12).
Is this configuration supported? → No, it is not supported.
Max. number of disk drives of 3.5” DAC: 12
Max. number of disk drives of 2.5” DE: 24
Number of disk drive slots in DAC: 12
Sum of disk drive slots in 3.5” DEs: 2 x 12 = 24
Sum of disk drive slots in 2.5” DEs: 5 x 24 = 120
Total: 156
This configuration has 144 disk drives, but 156 disk
drives slots that exceed 144 disk drive slots which
M300 supports the maximum.
This configuration is not supported.
Use with the same caution for other M-Series
models.
