Regarding Simpana's global deduplication, which one of the following statements is correct?
(single choice) Among the following OceanStor 9000 software features, which feature can provide file system snapshots?
Initiate quiescing of the application before the snapshot, and then trigger the hardware storage snapshot to create an application-consistent snapshot copy. Via snapshot
The backup copy is used for data backup, eliminates the data backup time window, does not interrupt the production system business at all, and achieves the difference of data
Save it locally and improve the reliability of the data.
What are the advantages of parallel data deduplication: (multiple choice)
(single choice) Which load balancing method does the Huawei OceanStor 9000 InfoEqualize feature not support?
In the Huawei remote replication solution, which of the following statements is correct?
1. Synchronous remote replication technology can achieve RTU=U, RPO=0,
2. Write data directly to the local storage, and quickly roll back and restore data through snapshot technology
E. A.1 wrong 2 right
F. B. 1 wrong 2 wrong
G. C. 1 pair 2 pairs
H. D. 1 right 2 wrong
What thresholds can be set for eReplication? (multiple choice)
In the use of OceanStor BCManager eReplication for disaster recovery switchover and fallback testing, the production end and disaster recovery
Both end arrays must support the snapshot feature.
(Judgment) Through the Huawei OceanStor 9000 Device Manager, we can view the real-time OPS performance indicators of the system.
In the following description of the asynchronous remote replication of the OceanStor V3 storage array, which one is wrong?
During the installation of Commserver, if cS and Agent are on the same network segment, there is no need to configure the hosts file.
Pieces.
The peak write bandwidth of an application is 10MB/s, the average write bandwidth is 200KB/s, and the average write IO size is 4KB (private
The information overhead is about 11%, and the bandwidth utilization rate is 70%). Use FC networking and set to synchronous remote replication mode (consider private
If there is information overhead), which is the correct requirement for network bandwidth?
The LUN size relationship between production storage and disaster recovery storage configuration remote replication is: the capacity of the secondary LUN is greater than or equal to the capacity of the primary LUN.
(multiple choice) Which of the following is correct in IDC's description of the characteristics of big data?
Huawei's end-to-end active-active data center solution is divided into 6 logical levels, namely storage layer, computing layer, application layer, and network layer.
Network layer, transport layer and security layer, the design points of each layer include: (multiple choice)
