Explanation:

Three-site triangle/multitarget replication

In three-site triangle/multitarget replication, data at the source storage array is concurrently
replicated to two different arrays at two different sites, as shown in the figure on the slide.
The source-to-bunker site (target 1) replication is synchronous with a near-zero RPO. The sourceto-remote site (target 2) replication is asynchronous with an RPO in the order of minutes. The
distance between the source and the remote sites could be thousands of miles.
This implementation does not depend on the bunker site for updating data on the remote site
because data is asynchronously copied to the remote site directly from the source. The
triangle/multitarget configuration provides consistent RPO unlike cascade/multihop solutions in
which the failure of the bunker site results in the remote site falling behind and the RPO
increasing. The key benefit of three-site triangle/multitarget replication is the ability to failover to
either of the two remote sites in the case of source-site failure, with disaster recovery

(asynchronous) protection between the bunker and remote sites. Disaster recovery protection is
always available if any one-site failure occurs.
