VMware vSphere and Live Volume
53 Dell EMC SC Series: Synchronous Replication and Live Volume | CML1064
As depicted in Figure 45, a Live Volume replication exists between SC Series A and SC Series B. Two
vSphere hosts are mapped to the Live Volume on each array. The Primary Live Volume is located on SC
Series A, and the Fixed preferred path (Figure 44) on each vSphere host is configured to use a path to SC
Series A as the preferred path.
Uniform Live Volume replication
If planned downtime will impact SC Series A, the preferred path for the vSphere hosts could be configured for
SC Series B. When the Live Volume is configured for automatic role swap, this change in preferred paths will
trigger the Live Volume to swap roles making SC Series B the Primary Live Volume controller, allowing SC
Series A to be taken offline without a disruption to virtual machines on that Live Volume.
8.5 Multi-site MPIO configuration
In a multi-site or non-uniform stretched cluster configuration, each vSphere host is zoned and mapped only to
its local corresponding array (see Figure 46).
