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
In a synchronous replication scenario, an application's peak write throughput is 16 MB/s, average
write throughput is 500 KB/s, average write 1/0 size is 8 KB, private information overhead is about
11%, and the FC network bandwidth utilization rate is 70%. The throughput of the disaster recovery
network must be at least ( ).
A physical standby database is kept synchronized with the primary database, through Redo Apply,
which recovers the redo data received from the primary database and applies the redo to the
physical standby database. Which of the following disaster recovery technologies is working as the
As shown in the figure, the main features of this backup network mode are:
A. Backup tasks will consume a lot of LAN resources.
B. Backup tasks will consume few LAN resources.
C. Backup tasks will consume a lot of CPU resources of the production system.
D. Backup tasks will consume few CPU resources of the production system.
In Huawei OceanStor 9000, the CA that processes write requests divides data into strips based on the
protection level and writes data strips into non-volatile dual in-line memory modules (NVDIMMs) if
the corresponding nodes. Then these nodes calculate and write parity strips into their NVDIMMs.
After all these nodes have successfully written parity strips, the write operation is successful.
Which commands are used to view SCSI controller information in RHEL5.5 (with Qlogic QLE2562-CK
In an application scenario, the I/O service model is random read, and the I/O size is about 100 KB.
Then, which is the proper stripe depth for LUNs on the storage system?
A. 8 KB
B. 16 KB
C. 64 KB
D. 128 KB
In an OceanStor V3 storage system, a disk domain has multiple types of disks. If one SAS disk is
added to the disk domain, all disks of the disk domain will participate in data balancing.
To use the storage space of OceanStor V3 more efficiently, a customer has specified file system
quotas for different departments. If a soft quota alarm is generated for the file system used by
department A, which methods can be used to clear the alarm and ensure that new data can be
