Detecting and evenly distributing client connection loads among nodes
The InfoEqualizer feature employs a load detection mechanism that can allocate access requests based on load balancing policies.

OceanStor 9000 V100R001C01 data recovery for a failed node
OceanStor 9000 V100R001C01 recovers data for a failed node using the following methods: 1. If the failed node turns normal, OceanStor 9000 V100R001C01 recovers data changes within the offline duration to a normal node and ensures zero loss of original data on the failed node. 2. If the offline node requires an operation by the administrator, OceanStor 9000 V100R001C01 obtains the data on the failed node through calculations and writes the data to disks of other normal nodes.
