Disaster recovery end must be deployed, oracle rac cluster can not deploy oracle single node.

Oracle RAC grid production side of the file must be copied to the disaster recovery side.

Unable to copy the production side of the FRA file will be able to guarantee the normal provision of services at the northern end.

Production end of the oracle data files and log files can not be placed in the same consistency group.

Dynamic domain name, which returns the dynamic IP address of the node for the client, supports the failover function and is recommended for CIFS protocol sharing

Static domain name, which returns the domain name of the node's static external IP address to clients, is recommended for NFS protocol sharing

dynamic external IP address, node failure, the dynamic IP address can be automatically assigned to other working nodes, the client can pass againThis IP address is connected to the OceanStor 9000

static external IP address, the node fails, the client can not access the oceanstor 9000 through the IP address

Standalone SAN engine and stand-alone file engine

Parallel dual-stack by way of parallel support (SAN) and file system (NAS)

Use unified storage pool technology

file system can achieve deduplication data compression function
