Abstract
Communication is arrested between a source data entity and a replicated data entity at a location declared in a DR mode. The DR mode is negotiated to a central replication management component as a DR mode entry event. The DR mode entry event is distributed, by the central replication management component, to each member in a shared group. The DR mode is enforced using at least one replication policy.
Claims19
A method of disaster recovery (DR) replication throttling in a computing environment by a processor device, comprising:
- sending, from a remote system including a replicated data entity, a request to a central replication management component to enter a DR mode as a result of a testing operation and negotiating the DR mode to the central replication management component as a DR mode entry event;
- arresting communication between a source data entity at a primary system and the replicated data entity at the remote system by configuring a first firewall at the remote system including the replicated data entity to all incoming replication activity from the source data entity;
- distributing, by the central replication management component, the DR mode entry event to each member in a shared group;
- configuring a second firewall at the source data entity at the primary system, in response to receiving the DR mode entry event from the central replication management component;
- and
- enforcing the DR mode by following one or more replication policies between a source system including the source data entity and a remote system, until a DR mode exit event is propagated to each member in the shared group.
