A. NameNode is the metadata request processing node of HDFS

B. NameNode is the data read request processing node of HDFS

C. NameNode switching will cause metadata service interruption

D. Only one Active NameNode provides metadata services

A. Before configuring basic services, import the license

B. When the data of the user application is stored in multiple luns, a lun group can be created to facilitate management

C. If you need to specify a specific port to connect to a service host, you need to create a port group to complete related operations

D. The business host is a cluster, and all hosts in the cluster are added to the same host for reference.

A. FALSE

B. TRUE

A. FALSE

B. TRUE

A. FALSE

B. TRUE

A. The customer needs to provide 9 management network IP addresses, of which 8 are used for IPMI management and 1 is used for OM management.

B. The customer needs to provide 49 IP addresses that can communicate with the client application client, of which 16 are used for static front ends, 32 are used for dynamic front ends, and 1 is used for InfoEqualizer DNS IP

C. The customer management network must communicate with the InfoEqualizer DNSIP of Huawei OceanStor 9000 to access Huawei OceanStor 9000 storage through domain names.

D. The customer needs to provide 16 IP addresses for the back-end IP of Huawei OceanStor 9000 system, and needs to provide a gateway.

A. Huawei Oceanstor9000 provides object storage service and is compatible with Amazon S3AP.

B. Huawei Oceanstor9000 supports simultaneous access to the same data in the same area from multiple nodes.

C. OceanstorDFS, a distributed file system developed by Huawei, supports the storage of large amounts of unstructured data.

D. Huawei Oceanstor9000 adopts the hardware of general x86 architecture and supports to expand from 3 nodes to 288 nodes.

A. raid5

B. raid3

C. raid6

D. raido

A. Determine the business requirements of each node, and carry out IP address planning and network end

B. Binding and other fixed management nodes support active-standby deployment mode

C. Make sure the port type of the storage node is 10GE Ethernet port

D. Calculate network bandwidth according to business requirements

A. The actual physical space occupied by the eDevLUN in the local storage system is the storage space required by the data volume

B. eDevLUN refers to third-party heterogeneous device volumes connected to Huawei storage

C. Application servers can access data on external LUNs through eDevLUNs

D. The eDevLUN consists of two parts: the actual data volume and the metadata volume, and the corresponding relationship between the metadata and the actual data is established through the mapping relationship

A. FALSE

B. TRUE

A. The relationship between the controllers in the cluster is equal. When a controller fails, the cluster switches the business to the controller with the lighter load according to the load of each controller.

B. The active-active member LUNs on the two sets of storage arrays in the cluster form a virtual active-active LUN through the real-time mirroring technology to keep the data of the active-active member LUNs in the two data centers consistent in real time.

C. All storage in the cluster provides undifferentiated parallel access to application servers.

D. FC or IP can be used as the communication link between site A and site B in the cluster: FC link can provide higher transmission efficiency: IP link is easy to deploy and has no distance limitation.
