A bank has more than XX customers and XX corporate customers.

Data loss will be huge and business disruption may result in significant financial loss.

Business interruption has a huge impact, and the interruption time in business deployment is less than 2 hours.

Clients want to build two live-action data centers in the same city to realize the key business activities such as RTO 2.

5 devices TOE NIC A0, B1, and A0, B3 inserted into the PCIe slot will not affect the system. Deployment will not affect the network bandwidth, so it cannot be adjusted.

The signal cables are long and need to be strapped to the cabinet or placed on the bottom tray.

Label NODE 01 A0-0 The signal cable is inserted in the network port A0-1. The signal cable labeled NODE01 B3-1 is inserted in the network position B3-0, due to the same network card two network port peer, you can place the wrong line, you cannot adjust.

CE6850 switch connected to two stacked copper cables, one of which is needed to post-cold more cold, because it does not affect the network interoperability. You can base this software debugging.

The namespace is automatically created when HUAWEI OceanStor 9000 is started with the same name as the system namespace.

Namespaces as the root directory of the entire system can not be shared and visited, only if ask the subdirectories below it can be shared and visited.

A unified namespace provide users with a unified storage resource pool to achieve the centralized management of storage space and distribution.

Each file share directory is a subdirectory of the namespace.

Disaster recovery end must be deployed, oracle rac cluster can not deploy oracle single node.

Oracle RAC grid production side of the file must be copied to the disaster recovery side.

Unable to copy the production side of the FRA file will be able to guarantee the normal provision of services at the northern end.

Production end of the oracle data files and log files can not be placed in the same consistency group.

To check the cluster node use the command:olsnodes -n

To check the cluster status use the command:crsctl check cluster -allcrsctl check crs

To check cluterware resource status use the command:crsctl stat ser -t

To check oracle ASM operating status use the command:ocrcheck

To improve the reliability of the video data storage device, the user turns on the securevideo feature of the data disk using a 4 + 1 protection level

The user turns on the securevideo feature, with two data corruptions if the data disk uses a 4 + 1 protection level and only 3 for a write operation

Users open the securevideo feature data consistency scanning, the system does not complete the data files, will be cleaned up

After the user turns on the securevideo feature, the file corruption event has been reported while reading and writing files, and the data recovery failure alarm is no longer reported

The shared disk file system uses the GPT format that caused the quorum disk to fail Online

The quorum disk can not be online due to the cluster feature that does not enable multipathing software

The MSCS Cluster service does not bring the volume resource online. The resource disk can not be online

Heartbeat network timeout causes arbitration disk and resource disk probability online

Synchronous remote replication and asynchronous remote replication should use the progress of the bitmap

The local storage system does not occupy the local storage system when using LUNs in heterogeneous storage systems

For external LUNs, the local storage system can set value-added functions such as remote replication, snapshots, etc.

smartVirtualization uses multipathing software to connect heterogeneous storage in a multipath-redundant manner

smartVirtualization Dictate write data write efficiency is higher than the write-back efficiency

Use 3-tier Tier, 1TB high performance layer, 4TB performance layer, 10TB capacity layer, and configure LUN1 to allocate high-performance layer capacity first, LUN2 preferentially allocates performance layer capacity and LUN3 preferentially allocates capacity layer capacity

Use 3-tier Tier, 1TB high-performance layer, 4TB performance layer, 10TB capacity layer, configure LUN1 and LUN2 to migrate automatically, and LUN3 priority allocation of low-performance layer capacity

The use of 3-tier Tier, high-performance layer 1TB, performance layer is 4TB, capacity layer is 10TB, while configuring LUN1, LUN2, LUN automatic relocation. The LUN3 is migrated preferentially to the low-performance layer

Set the monitoring period of the Smart tier to 8:00 to 18:00 every day from Monday to Friday. The migration period is not overlapped with the monitoring period

A quota tree can be shared using a protocol. In addition, a quota tree that is being shared cannot be renamed or deleted.

You can move files (NFS protocol) or cut files (CIFS protocol) across quota trees.

A hard link cannot be established between two different quota trees.

An administrator can delete non-empty quota trees through CLI or GUI.

All controller nodes are in normal state

The number of partitions created has not reached the limit

Engine remaining cache of not less than 256M

Create a partition read and write cache the same size

It does not consume any host resources.

It is lower in migration cost than gateway-layer solutions such as those based IBM SVC, and EMC VPLEX.

It requires services to stop only once, and the service stopping occurs after the migration.

It delivers higher migration speed than host-layer solutions.

True

False

After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated at the same time

Disaster recovery data stored in the Cache, not yet written to the hard disk

When creating a snapshot on the disaster recovery end LUN The production end is copying data to the disaster recovery end

The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy. The incremental data is abnormally interrupted during the synchronization process and has not been recovered
