Precautions for creating a remote link for a V3 series unified storage system
The precautions for creating a remote link for a V3 series unified storage system V300R002 are as follows: 1. If a Fibre Channel network is used, set Link Type to FC. If an IP network is used, set Link Type to iSCSI. 2. If the storage systems at the two ends are of different versions, initiate link creation from the storage system with the later version. Otherwise, the link creation fails.

Average bandwidth of V3 remote replication
For the two links of asynchronous remote replication, one is the service link connecting the server and primary storage and the other is the replication link connecting the primary storage to the secondary storage. You need to consider average bandwidth and ensure that the average bandwidth of service links must be smaller than the average bandwidth of replication links. Otherwise, if data delivery is faster than data replication, data will be overstocked, resulting in remote replication interruption.

Configuring the HyperMetro feature for V3 series unified storage systems
If the HyperMetro feature is configured, two data centers serve as a backup for each other. If one data center fails, services are automatically switched to the other data center without data loss or service interruption. For the procedure of configuring the HyperMetro feature, see http://support.huawei.com/enterprise/docinforeader.action?contentId=DOC1000084209&idAbsPath=7919749|7941815|21430818|21462748|21041235.
