Configuring replication
21 Dell EMC SC Series: VMware Site Recovery Manager Best Practices | 2007-M-BP-V
abstraction layer to the replication to allow mapping of an abstracted volume derived across two SC Series
arrays.
SRM support for stretched storage with Live Volume was added in DSM 2016 R1 and further improved in
DSM 2016 R3.11. Supported configurations are asynchronous replication or synchronous high availability
replication with non-uniform storage mapping to hosts. For more information about use cases and integrating
stretched storage with SRM, see the Site Recovery Manager Administration guide at VMware Documentation.
The use of Live Volume stretched storage in protection groups requires asynchronous or synchronous high
availability replication and non-uniform storage mapping. Live Volume automatic role swap and automatic
failover must be disabled.
The following are not supported in conjunction with SRM: synchronous replication in high consistency mode,
uniform storage mapping, managed replication, consistency groups, Live Volume automatic role swap, and
Live Volume auto failover.
Using Unisphere Central to perform Activate Disaster Recovery of a Live Volume managed replication is a
good use case for remote disaster recovery of a Live Volume. However, Live Volume managed replications
are not explicitly supported with vSphere SRM. Live Volume managed replication volumes are activated using
Unisphere Central.
5.5 Data consistency while replicating the frozen snapshot
Figure 6 and the steps that follow describe the consistency states of replications during plan execution while
replicating a frozen snapshot.
