6 Dell EMC SC Series: Synchronous Replication and Live Volume | CML1064
Executive summary
Preventing the loss of data or transactions requires a reliable method of continuous data protection. In the
event of a disaster or unplanned outage, applications and services must be made available at an alternate
site as quickly as possible. A variety of data mobility methods, including asynchronous replication, can
accomplish the task of providing offsite replicas. Synchronous replication sets itself apart from the other
methods by guaranteeing transactional consistency between the protected site and the recovery site.
While remote replicas have traditionally provided a data protection strategy for disaster recovery, the disaster
itself and the execution of a disaster recovery (DR) plan involves a period of downtime for organizations.
Replicas along with storage virtualization can provide other types of data mobility that fit a broader range of
proactive high availability use cases without an outage.
This guide focuses on two of the main data protection and mobility features available with Dell EMC™ SC
Series storage: synchronous replication and Live Volume. In this paper, each feature is discussed and use
cases are highlighted where these technologies fit independently or together.
