Disk Redundant Backup

Availability:

This feature was introduced in M2000 V200R002.

Description:

The local disks of the M2000 support the RAID 1 backup mode (1+1 disk mirroring).
The supported redundancy solutions vary according to disk array types. Sun 6140, Sun 3320,
OceanStor S3100, and OceanStor S3200 disk arrays support the RAID 5+Hotspare mode. Sun
6180, OceanStor S2600, and OceanStor S3900 disk arrays support the RAID 10+Hotspare

mode.

Dual Plane Communication

Availability:
This feature was introduced in M2000 V200R002.

Description:
The M2000 supports the dual-plane networking of operation and maintenance, and two
independent communication links form an O&M network. The M2000 automatically monitors
the communication status of both channels. The routine communication is performed on the
active plane. If the active plane is faulty, the M2000 automatically switches the
communication to the standby plane to ensure the reliability of the O&M network.
