OceanStor Pacific series file services can connect to mainstream computing servers and provide standard NAS protocol access capabilities by providing standard NFS protocol, SMB protocol, POSIX interface protocol and MPI interface protocol.
- A . True
- B . False
For a block storage system, to achieve disaster recovery scenarios over long distances and with limited network bandwidth, which of the following methods can be used for remote replication?
- A . FS asynchronous remote replication
- B . LUN synchronous remote replication
- C . FS synchronous remote replication
- D . LUN asynchronous remote replication
The file system quota feature is called SmartQuota. This technology can control resources for three types of resource users: (), users, and user groups.
The two-site three-center disaster recovery solution adopts the "active-active + synchronous + asynchronous parallel" networking architecture. Which of the following is wrong about its disaster switching processing?
- A . After the off-site disaster recovery center takes over the business from the LUN, the disaster recovery center array will record the differential data for subsequent incremental recovery, shortening the time for business switchback.
- B . Array A in production center fails, but array B in production center continues to provide services.
- C . When both the arrays in production center A and production center B fail, the off-site disaster recovery center should first resume operations.
- D . After the failure of array B in production center, array A in production center continues to provide services.
The active-active replication network between arrays must use a dual-switch networking method, that is, there are two independent networks from each host to the array to ensure that when any network fails, it will not interfere with the normal use of the other network.
- A . True
- B . False
In a company data center, the host system installed Huawei multipath software and connected to the storage device through multiple links. There was a LUN on the storage device that was mapped to multiple hosts at the same time, but some hosts could not access the LUN. The storage engineer enabled the multipath software load balancing function and selected the FIFO (First Input First Output) mode to solve the problem.
- A . True
- B . False
Which of the following descriptions of DMEIQ’s intelligent analysis are correct? (Multiple choice)
- A . Intelligently identify equipment performance anomalies and provide analysis suggestions to nip performance issues in the bud and ensure stable business operation.
- B . DMEIQ uses AI to dynamically analyze changes in hard drive logs and fluctuations in hard drive performance indicators. It also combines Huawei’s built-in hard drive location log correlation analysis to ensure more accurate predictions and provide a lifespan estimate.
- C . Full-stack visualization from VM to storage to quickly discover storage network performance issues.
- D . Quickly diagnose database performance anomalies and locate the root cause of the problem.
Huawei OceanStor scale-out storage provides a three-tier distributed storage architecture. Which of the following items belong to this architecture? (Multiple choice)
- A . Storage hardware layer
- B . Storage engine layer
- C . Storage Interface Layer
- D . Storage service layer
Due to technological changes, dynamic scaling and frequent changes in storage services have brought higher capability requirements to operation and maintenance.
- A . True
- B . False
The two-site three-center disaster recovery solution adopts the "synchronous + asynchronous cascade" networking mode. Disk array A is deployed in the production center, disk array B is deployed in the disaster recovery center in the same city, and disk array C is deployed in the disaster recovery center in a different location.
Which of the following is wrong about the introduction of this networking method?
- A . Disk array A and disk array B establish synchronous remote replication
- B . The data of disk array B is synchronized to array C regularly
- C . Disk array B and disk array C establish synchronous remote replication
- D . The production center A and the disaster recovery center B are interconnected through FC links
