Live Volume use cases
99 Dell EMC SC Series: Synchronous Replication and Live Volume | CML1064
11 Live Volume use cases
This section exhibits additional examples of how Live Volume can be used in a variety of environments. Live
Volume is not limited to these use cases.
11.1 Zero-downtime SAN maintenance and data migration
With Live Volume, maintenance activities can be performed without downtime on an SC Series array. This
includes tasks such as taking an array offline to move its location, perform service-affecting enclosure or disk
firmware updates, and migrate the volume to a new SAN.
The requirements for this operation include:
• MPIO installed and appropriately configured on the host computers
• Server(s) properly zoned into both SC Series arrays
• Server(s) configured on both arrays
• At least a 1 Gb low-latency replication link between arrays
Summary: In advance of a planned outage, Live Volume can non-disruptively migrate volumes from one SC
Series array to another, enabling continuous operation for all applications — even after one array has
completely powered down.
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:
• Redefine remote site as primary for all volumes on local site
• Shut down local site
• Reverse process after planned outage is completed
Maintaining availability of applications and services during scheduled maintenance
