Configuring HyperMetro

This section describes how to configure the HyperMetro feature.

• Creating a Replication Cluster
  Creating a replication cluster includes creating a replication control cluster and a replication service cluster, configuring the replication network, and authenticating the replication cluster. You must create a replication cluster in both primary and secondary storage systems.
• Creating a Quorum Server
  This operation enables you to create a third-party quorum server for HyperMetro domains. When the communication between storage devices in a HyperMetro pair becomes abnormal, the quorum server decides which site continues to provide services, thereby greatly improving service continuity.
• Creating a HyperMetro Domain
  After configuring a remote device and a quorum server, you need to create a HyperMetro domain for the remote and local devices, and the quorum server. When creating a HyperMetro domain, determine the relationships among the local device, remote device, and quorum server in the domain.
• Creating a HyperMetro Pair
  This section describes how to define HyperMetro relationships and data synchronization properties between the storage resources on two storage systems, achieving active-active storage. In the event of a disaster, the arbitration mechanism of HyperMetro determines the site that can continue providing storage services to implement DR.
• Creating a HyperMetro Consistency Group
  If an application or one type of services requires multiple HyperMetro volumes and a preferable service site needs to be determined by the system or quorum server upon faults, you need to add HyperMetro pairs of the owning volumes of the application and services to a same HyperMetro consistency group for unified maintenance.
