A failover group is a combination of ports that are used for IP address failover in a storage system, and IP address failover ensures service continuity and improves the reliability of paths for accessing file systems. IP address failover applies to all storage network architectures, not just IP SAN. Fallback means that the standby port takes over services when the active port fails, and then the active port takes over services again after it recovers.

The main functions of the business continuity solution are to minimize the impact on the business service, ensure zero data loss and zero service interruption, and improve the utilization rate of the disaster recovery equipment. Predicting the disaster occurrence accurately is not a function of the business continuity solution.

A and C are true statements about the ports of a Huawei OceanStor all-flash storage device. Bond ports, VLANs, and logical ports are created based on available Ethernet ports, while multiple Ethernet ports of the same controller are bonded to form a bond port to increase the bandwidth. The networks and services between VLANs are physically isolated, which improves the security and reliability of service data. Multiple logical ports can be created for a bond port, but only one logical port can be created for an Ethernet port.

The IP SAN can use the existing IP network, and it supports the iSCSI protocol. The FC SAN must be configured with dedicated iSCSI HBAs for servers, and the FC HBA used by the FC SAN cannot convert SCSI packets into FC packets.
