3. Select the type of the replica pair you want to create and configure parameters by referring to Table 1.

   Table 1 Parameter description

   Parameter		Description	Example Value
   Type		Type of the replica pair The supported types are IDC-to-cloud, Cross-region and Cross-AZ.	Cross-AZ
   Scenario		Select the replication scenario you want to set up. The supported scenarios are H2C (private cloud disaster recovery to public cloud) and V2C (VMware disaster recovery to public cloud). NOTE: This field shows up only when you are creating an IDC-to-cloud replica pair.	H2C
   Name		Name of the replica pair The name can contain letters, digits, underscores (_), hyphens (-), or periods (.), can be no more than 64 characters long, and cannot contain spaces.	Site-replication-001
   Production Site NOTE: You only need to configure the production site when creating a cross-region or cross-AZ replica pair.	Region	Region where the production site resides NOTE: You only need to select a region when creating a cross-region replica pair.	-
   	AZ	AZ where the production site servers reside NOTE: You only need to select an AZ when creating a cross-region or cross-AZ replica pair.	AZ1
   	Network	VPC where the production site servers reside	VPC01
   Disaster Recovery Site	Region	Region where the disaster recovery site resides Select the region you selected when you set up the disaster recovery network. For details, see Preparation: Set Up a Disaster Recovery Network on the Cloud. NOTE: You only need to select a region when creating an IDC-to-cloud or a cross-region replica pair.	-
   	AZ	AZ where the disaster recovery site servers reside	AZ2
   	Network	VPC where the disaster recovery site servers reside	VPC02

   1. Cross-AZ: The production site and disaster recovery site are located in different AZs of the same region.
