A customer has an environment that spans two data centers in a campus environment. The
primary storage is HP 3PAR 10400, and data is replicated between sites with an RPO of zero.
Recent bad weather has caused flooding near the customer site and the customer is questioning
whether they have adequate protection. You suggest creating a data center at a remote location
and actively replicating the data to it. The customer is concerned that the remote link to the third
site will have insufficient bandwidth and will create a local replication bottleneck.
Which statement addresses the customer concerns?
A.
Synchronous Long Distance will schedule data replication outside high latency periods
autonomic array
B.
Data is transmitted in a continuous stream with write order being handled by the target array.
C.
Remote Copy uses multiple connections over the same link from multiple volumes.
D.
Over provisioning of the remote link will ensure enough bandwidth is always available for
replication.
Explanation:
A. Primary array sync to campus secondary (Target 1) and Synchronous Long Distance (SLD) to the remote secondary (Target 2). SLD combines synchronous and periodic asynchronous replication to replicate a Remote Copy group to two separate target arrays.
