Use the same generation drive type and capacity size when conguring RAID setting.
■
Add or replace a drive with another drive of the same gener
ation.
■
The spar
e drives associated with an arr
ay group consisting of rst generation Flash Module
Drives (FMD) must also be a rst generation FMD. The spare drives must have the same or
larger capacity as the FMD drives in the array group.
■
The spare drives associated with an array group consisting of Flash Module Drive (FMD) DC2
drives must also be an FMD DC2 of the same generation. The spare drives must have the
same or larger capacity as the FMD DC2 drives in the array groups.
Follow the listed examples:
●
Array group consisting of 1.6 TB FMD requires the same generation 1.6 TB FMD drive as a
spare.
●
Array group consisting of 3.2 TB FMD requires the same generation 3.2 TB FMD drive as a
spare.
●
Array group consisting of 1.6 TB FMD DC2 requires the same generation 1.6 TB FMD DC2
drive as a spare.
●
Array group consisting of 3.2 TB FMD DC2 requires the same generation 3.2 TB FMD DC2
drive as a spare.
●
Array group consisting of 6.4 TB FMD DC2 requires the same generation 6.4 TB FMD DC2
drive as a spare.
