A.The request is sent in the sequence of the cache in the primary storage, disks in the primary storage, cache in the secondary storage and disks in the secondary storage.

B.The request is sent to the cache in the primary storage, and the cache sends it to the cache in the secondary storage.

C.The request is sent to the cache in the primary and secondary storage at the same time,

D.The request is sent to the cache in the primary storage, and then multi-time-segment caching is enabled to synchronize the request to the cache in the secondary storage.

A.When one of the mirror copies fails, the business on the LUN is not affected in any way, and the host side can still work normally

B.can configure other value-added features for LUNs that are protected by volume mirroring to provide multiple protections for data

C.provides two mirror copies of a LUN, and the data in these two copies is exactly the same

D.This continuously protected LUN can be the LUN of a third-party storage system

A.After creating an asynchronous remote replication relationship, you need to do an initial synchronization.

B.When adding a secondary LUN for asynchronous remote replication, the system automatically creates and activates a snapshot of the primary and secondary LUN.

C.In the asynchronous remote replication process, after the write I/O of the primary LUN is successful, the primary array returns the write I/O success to the host.

A.The source and target LUNS belong to the same controller.

B.The target LUN has no value-added services.

C.The target LUN is not mapped to any host.

D.The target LUN is not smaller than the source LUN.

A.Node throughput

B.CPU usage

C.User group

D.Node-connections
