Caution:
When correcting a power supply mismatch, replace only
the power supply with the flashing indicator. Swapping the
opposite power supply to make a matched pair can result
in an error condition and unexpected system shutdown. To
change from a High Output configuration to an Energy
Smart configuration or vice versa, you must power down
the system.
Caution:
The AC power supplies, which come with the system,
support both 220 V and 110 V input voltages. When two
identical power supplies receive different input voltages,
they can output different wattages, and trigger a
mismatch.
Caution:
Combining AC and DC power supplies is not supported and
triggers a mismatch.
StorNext M330
Metadata Array
The StorNext M330 features a single Metadata Array.
StorNext M330 Metadata Array
The StorNext M330 Metadata Array features a- 24-drive 2U storage
enclosure. The StorNext M330 metadata array contains SAS hard disk
drives and provides storage for the StorNext File System metadata and
journal. The first drive of the metadata array is a global hot spare, and
the next six are configured into three 1+1 RAID-1 mirrors. These
mirrored sets are split into two stripe groups (SGs): SG0 combines three
Alternating green and amber
When hot-adding a power supply, this indicates that the
power supply is mismatched with the other power supply (a
high-output power supply and an energy smart power supply
are installed in the same system). Replace the power supply
that has the flashing indicator with a power supply that
matches the capacity of the other installed power supply.
