A customer's database application is running on an OceanStor V3 storage system. The database uses
six LUNs. The customer wants to migrate data from the OceanStor V3 storage system to an OceanStor
18000 series storage system based on the functions provided at the storage side. Which statements
Which statement about SmartMigration functions is false during a SmartMigration-based migration?
When the data migration solution based on remote replication is used, services must be suspended
at least once.
Huawei HyperMetro active-active disaster recovery supports heterogeneous storage. Therefore, an
OceanStor V3 storage system and a Huawei certified third-party storage system can work in active-
active mode based on HyperMetro.
An application's peak write throughput is 10 MB/s, average write throughput is 280 KB/s, average
write I/O size is 4 KB, and the network bandwidth utilization rate is 70%. If OceanStor V3 storage
systems are used to implement data disaster recovery based on asynchronous replication,
Synchronization Method is set to Timed wait when synchronization begins, and the value of Interval
is 4 hours, the expected duration to synchronize data is no more than 1 hour. So the minimum
network throughput should be (_).
A. 1600 KB/s
B. 400 KB/s,
C. 15 MB/s
D. 10 MB/s
