Huawei H13-629 Exam Success: HCIE-Storage (Written) Complete Study and Preparation Tips

In the scenario where the actual RPO indicator requires zero, you can choose to synchronize remote replication.

Synchronous remote replication canbe used to map the main and secondary storage of the two sets of LUN mapping to the host to create a scenario volume.

Synchronous remote replication on the remote disaster recovery can be well done.

Because synchronous remote replication does not usesnapshots, after synchronous remote replication is interrupted abnormally, the data on the primary LUN needs to be resumed in reply.Start synchronization to the slave site.

When using the InfoEqualizer function, you need to configure DNS. If you use an external DNS server, when configuring the DNS server, there is a setting of "reverse lookup zone name", network ID setting in this tab, you need to input network ID in reverse order.

When there is a DNS server in the user network, the DNS server in the user network does not need to configure the forwarding record. When the user network without DNS service server, configure the InfoEqualizer DNS IP address as the DNS server's address on the client.

The root domain name is the domain name InfoEqualizer configured for the cluster. This domain name must be configured as the fully qualified domain name, that is, the domain name that includes the root node.

The domain name of the partition is configured as the relative domain name, and the root domain name of the InfoEqualizer is automatically taken as the suffix of the domain name, and the full name of the domain name is formed with maximum support of 32 partitions.

Stop the current production business

Add the remote device to the original production array

With the disaster recovery array as the master LUN and the original production array as the slave LUN, create the remote replication relationship between the DR and the production end and wait for the initial synchronization to be completed.

Make an incremental synchronization.

Delete theoriginal production array consistency group.

Parallel dual-stack by way of parallel support (SAN) and file system (NAS)

Use unified storage pool technology

The mode of operation of the array can be in-controller load balancing or inter-controller load balancing.

Load Balancing Mode Including wheel training algorithm, the maximum queue depth algorithm, the maximum workload algorithm.

After the connection is interrupted between the LUN home controller and the host, the host accesses the LUN through the peer controller. In this case, the over-trail software defaults the switched home controller of the LUN to the remote controller.

When multipath detects a preferred controller failure recovery, the I / O is resumed immediately at the preferred controller by default.
