Unlike most DNS load technologies, the OceanStor 9000 load balancing service directly integrates the DNS query function. Users do not need to deploy the DNS service. If any server fails, a switchover policy is configured to ensure normal access.
OceanStor 9000 manages the access IP addresses provided by nodes in the cluster in a unified manner, supports automatic IP address allocation for newly added nodes, (failover) failover for node IP addresses, and (failback) for fault recovery. You only need to configure an IP address pool for OceanStor 9000, you do not need to configure each node one by one. The management of the entire IP address becomes easier for users and is easy to handle during cluster capacity expansion.
