Live Volume overview
35 Dell EMC SC Series: Synchronous Replication and Live Volume | CML1064
• Supports asynchronous or synchronous replication and included features such as:
- Snapshots
- High consistency and high availability modes
- Mode migration
- DR activation for Live Volume managed replications
• Supports an additional asynchronous or synchronous Live Volume replication to a third array created
and dynamically managed by Live Volume
• Provides automatic or manual Live Volume failover and restore in the event of an unplanned outage
at a primary Live Volume site
• Includes VMware vSphere Metro Storage Cluster (vMSC) certification with SCOS 6.7 and newer
Live Volume is designed to fit into existing physical and virtual environments without disruption or significant
changes to existing configurations or workflow. Physical and virtual servers see a consistent, unchanging
virtual volume. Volume presentation is consistent and transparent before, during, and after migration. The
Live Volume role swap process can be managed automatically or manually and is fully integrated into the
array and Dell Storage Manager. Live Volume operates asynchronously or synchronously and is designed for
application high availability during planned migration, resource balancing, disaster avoidance, and disaster
recovery use cases.
A Live Volume can be created between two SC Series arrays residing in the same data center or between
two well-connected data centers with Fibre Channel or iSCSI replication connectivity.
Using Unisphere Central for SC Series, a Live Volume and an optional Live Volume managed replication can
be created. For more information on creating a Live Volume, see the appropriate Dell Storage Manager User
Guide provided with the DSM software.
