True

False

During the startup of the OceanStor 9000, a namespace is automatically created with the same nameas that of the OceanStor 9000.

As the root directory of the entire system, a namespace cannot be shared or accessed, However, its subdirectories can be shared and accessed,

A unified namespace provides a unified storage resource pool where storage space can be centrally managed and allocated.

All shared directories are subdirectories in the unified namespace,

The console IP address conflicts with another IP address on the network.

The network port corresponding to the console IP address is not connected to a network cable or is in the shutdown state.

The user name and password have been changed.

A heartbeat link is down.

A power module runs properly ifits indicator is steady red.

The system is being started if the power indicator on the NAS service module blinks green.

The data transmission rate is 4 Gbit/s if the port indicator on the NAS service 10GE interface card is steady blue.

Data is being transmitted if the Active indicator of the management network port blinks orange.

The N8500 supports a maximum of two mirrors for a single file system.

Resources of different storage pools can be selected to implement file system mirroring.

File system mirroring allows users to select three mirroring layout types.

In the same service scenario, mirrored-stripe and striped-mirror provide the same data reliability and performance.

The cluster name can be set to9000cluster.

If the InfoLink license has not been purchased, you may skip the InfoLink DNS configuration.

The front-end network gateway will serve as the default gateway of all storage nodes after being configured.

The data redundancy ratio is thedefault ratio of all directories on the OceanStor 9000.

The maximum supported file system capacity is40 PB.

The maximum supported data recovery speed is 1 TB/hour.

Each node uses the cache on the node exclusively.

Thin provisioning and thick provisioning are both supported.

The bond4 mode has unbalanced load issues in the "gatewayed" topology.

The bond6mode allocates and adjusts loads based onthe workloads on the bond ports.

The bond6 mode supports fault tolerance whereas the bond4 mode does not.

The adaptive load balancing supported by the bond6 mode will definitely cause frequent switchovers among network adapters, increasing the systemoverhead.

Before installing software, configure switches on the back-end storage network and the management network.

The OceanStor Toolkit must be installed on all storage nodes.

The OceanStor SystemReporter can be installed on any Windows server with qualified hardware and software.

You must purchase a license for the OceanStor SystemReporter.

False

A create policy is used to determine the initial location where a newly created file is to be stored. Such a policy includes the following items:file storage path, file name, and UID/GID.

A relocate policy is used to determine the target location where a file is to be migrated.

A delete policy is used to determine when to delete a file from the system.

A modify policy is used to determine how to modify a file.

Data collection is implemented based on data sources. Attention must be paid to the use of structured and unstructured database technologies.

Data storage resolves the massive data storage issue. Attention must be paid to data variety and heterogeneous data convergence.

Data processing features high velocity.Attention must be paid to the parallel computing technology.

Data analysis and application highlight data value. Attention must be paid attention to data mining, business intelligence, and data search.

CIFS normal share enables a directory to be accessed by all users.

CIFS homedir share enables a directory to be accessed by all users.

In Normal mode, a client can access a share through only one VIP.

Compared with the Normal mode, the Cluster mode provides higher data reliability but lower performance.

The agent monitors the resources of each system and provides the status information for the HAD of each machine.

If a cluster node is abnormal or faulty, the HAD takes correct actions, for example, performing a failover.

The GAB implements a point-to-point communication mechanism. The master node sends the other cluster nodes the information that needs to be synchronized.

LLT is a MAC-layer protocol unrelated to IP layer.

Check whether the BBUs are faulty. If only one BBU is faulty, the current write policy of LUNs changes to write through.

Log in tothe ISM and check whether alarms indicating slow disk response exist.

Check on the ISM whether bit errors exist on Fibre Channel ports.

Check whether front-end service ports are functioning at the optimal rate. For example, check whether the port rate is 4 Gbit/s when the bandwidth is 8 Gbit/s.

Monitors GAB and checks the changes of cluster members.

Ensures the single view of cluster members.

Prevents multiple nodes from using a volume manger to access the shared storage.

Automatically recovers the master node if the cluster becomes abnormal.

You can classify nodes as needed. For each partition load balancing system, you can configure independent load balancing policies and independent access domain names.

The load balancing strategy can be based on: CPU, memory, bandwidth, network connections, node capability values

Oceanstor 9000 load balancing service support: round robin mode, CPU usage, number of node connections

The unit of FTP sharing is the directory, and the shared directory can be accessed by multiple clients.

Provides service node status for load balancing, and data access is evenly distributed within the cluster.
