(single choice) Which load balancing method does the Huawei OceanStor 9000 InfoEqualize feature not support?
(multiple choice) The value of Huawei OceanStor 9000 InfoTier is reflected in:
(multiple choice) In an OceanStor 9000 system, the total number of nodes is 10, and the data protection levels that can be configured for it are:
(Judgment) FusionStorage Block uses a unique data block slicing technology and data based on DHT Hash
The routing algorithm can evenly distribute the data of the volume to the fault domain of a larger resource pool, so that each volume can obtain a larger
IOPS and MBPS performance also makes the load of each hardware resource relatively balanced.
(multiple choice) The value of Huawei OceanStor 9000 InfoTier is reflected in:
(multiple choice) OceanStor 9000 adopts Erasure code technology to protect data. If a site has 6 nodes,
And the customer wants to ensure that the data can be recovered even if three disks are broken in one strip, the redundancy protection levels that can be adopted are:
File-level deduplication is also called single-instance storage (SIS). It checks the attributes of the files to be stored according to the index and compares them with the stored files.
For comparison, if there is no identical file, store it and update the index, otherwise only store the pointer to the existing file.
In a backup structure with a primary backup domain and multiple branch backup domains, the following description is wrong:
(single choice) Among the following OceanStor 9000 software features, which feature can provide file system snapshots?
Before deploying Huawei's active-active solution, the customer's current multi-selection network information that needs to be collected includes: (multiple selection)
(multiple choice) The daily inspection performance indicators of the big data storage system include:
(Judgment) Through Huawei OceanStor 9000 Device Manager, we can view the real-time OPS performance indicators of the system.
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.
(single choice) In which of the following situations, the Huawei OceanStor 9000 system will not start load balancing?
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.
