RAID 5 and RAID 6 can meet the requirements as they both improve data reliability by storing parity data on different disks. RAID 0 and RAID 3 do not store parity data on different disks, so they would not meet the bank's requirements.

The statements that describe the high reliability of the Huawei OceanStor all-flash storage system are A. It supports clusters consisting of multiple controller enclosures to improve the availability of the storage system, B. Interconnect I/O modules shorten failover time when a controller fails to provide better reliability, as compared with common I/O modules, and D. When a controller fails, l/Os of the faulty controller are redirected to another controller The host is unaware of the fault and services remain running properly. Statement C. Standard I/O modules shorten failover time when a controller fails to provide better reliability, as compared with interconnect I/O modules is false.

In active-standby mode, only one controller works at a time and if one controller is faulty, services are not affected. In active-active mode, both controllers are active and the service failover is more efficient than in active-standby mode.

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.
