Live Volume use cases
102 Dell EMC SC Series: Synchronous Replication and Live Volume | CML1064
11.4 On-demand load distribution
In this use case, Live Volume transparently distributes the workload, balances storage utilization, or balances
I/O traffic between two SC Series arrays.
Configuration: SC Series arrays must be connected using high-bandwidth and low-latency connections,
especially when synchronous replication is used with Live Volume.
Operation: In an on-demand, operator-driven process, Live Volume can transparently move volumes from
one SC Series array to another. The applications operate continuously. This enables several options for
improved system operation:
• Distribution of I/O workload
• Distribution of storage
• Distribution of front-end Ioad traffic
• Reallocation of workload to match capabilities of heterogeneous systems
On-demand local distribution
11.5 Cloud computing
In this use case, Live Volume transparently distributes the workload, balances storage utilization, or balances
I/O traffic between multiple SC Series arrays within a data center, enabling continuous flexibility to meet
changes in workload and to provide a higher-level system up time.
Configuration: Live Volumes can be created between any two SC Series arrays in a data center. Each array
can have many Live Volumes, each potentially connecting to a different array.
