In Huawei OceanStor hybrid flash storage, the data, logs, and modification information of a database application are stored in the primary LUDN1, primary LUN2, and primary LUN3 respectively, and asynchronous remote replication is created for the three primary LUNs. When the primary LUIN2 fails, the database can be started normally through the primary storage system after the data of the primary storage system is restored using the secondary storage system.
- A . True
- B . False
In the OceanStor 9000 system, the InfoEqualizer partition cannot be P.
- A . True
- B . False
Distributed storage can be used as an independent network element to connect to eSight and OceanStor services.
- A . True
- B . False
Distributed storage, file storage and object storage can share storage space with block storage and switch freely.
- A . True
- B . False
When building a large-scale FC storage network, you will encounter the scenario of FC switch cascading, when multiple FC switches are cascaded.
Which of the following scenarios will cause the switch to isolate the E Port? (Multiple choice)
- A . FC switch name conflict
- B . Conflict occurs in the zones of the FC switch
- C . The IP address of the FC switch conflicts
- D . The FC switch domain ID conflicts
Which of the following businesses can use SmartTier features to improve storage system performance and reduce user costs? (Multiple choice)
- A . ERP
- B . Data Mining
- C . Online shopping
- D . Data warehouse
Which of the following statements about Thin LUN are correct? (Multiple choice)
- A . After enabling the SmartThin feature, users can create a Thin LUN that is larger than the maximum physical available space in the storage pool.
- B . Thin LUN cannot be directly converted to Thick LUN
- C . All LUNs in a storage pool need to enable SmartThin.
- D . Thin LUN consumes very little storage capacity when it is created.
Which of the following descriptions of high-performance technology in HyperMetro is correct? (Multiple choice)
- A . In the preferred array mode, when the host service accesses the space, I/O will only be load-balanced and delivered on the preferred array path set by the user. If this mode is configured, the arbitration server mode cannot be configured.
- B . HyperMetro uses the host I/O granularity to add distributed range locks to the LBA intervals between host I/O accesses for concurrent mutual exclusion, thereby achieving the purpose of two-way real-time synchronization. This solution can save unnecessary data transmission bandwidth between arrays and effectively reduce the number of data transmissions.
- C . HyperMetro optimizes the data transmission between arrays at the protocol level through the FastWrite function and applies the First Burst Enabled function of the SCSI protocol, reducing the number of link transmission intersections for write data by half.
- D . Simplified copy uses hardware chips to quickly identify the data copy source. Find the zero data, and during the copy process, specially mark the all-zero data, and only transmit a small special page to the other end instead of the full data.
Which of the following descriptions of HyperMetro’s arbitration server mode is wrong? (Multiple choice)
- A . It is recommended that the arbitration server be deployed in a data center with good storage performance. When arbitration is required, high-performance storage can more easily win and continue to provide services.
- B . In arbitration server mode, if a site has priority in obtaining genres, you can also configure site priority. The priority array has the priority to win the genre. If the heartbeat is interrupted but other functions are normal, the priority array will win the genre.
- C . The active-active domain contains array A, array B, and the arbitration server. If array A and the arbitration server fail at the same time, array B survives and continues to provide services.
- D . If the arbitration server fails, the business will continue to operate normally.
A customer’s business application uses a Huawei OceanStor hybrid flash storage system with three pools, all of which are 8D+1P RAID5. One day, a business interruption occurred, and engineers found some scenarios that caused the failure by analyzing the logs.
Which of the following scenarios will cause interruption of host access to storage services? (Multiple choice)
- A . In a fully redundant network environment, the master controller is reset.
- B . The POOL where the service is located contains only ThinLUNs and no snapshots, LIN copies, clones, or services are configured. The log contains information indicating that the POOL space is full.
- C . When the BST (bad track mark) function is disabled, BST bad tracks appear on the LUN.
- D . The log contains the following printouts:
[2014-01-19 08:04:40] [Receive a disk-fault event of the disk (328) of pool (2) from Ctrl.]
[2014-01-19 08:40:35] [Receive a disk-fault event of the disk (613) of pool (3) from Ctrl.]
