Mobility
The Data Mobility feature allows you to non-disruptively move data on extents or devices to other extents or devices in the
same cluster, or from devices in one cluster to devices in another cluster. Mobility contains wizards that allow you to create
mobility jobs, and view the status and progress of those jobs. You create a mobility job to specify where to move data from
(source) and where to move data to (target). Use data mobility to perform these tasks:
● Consolidate data centers.
● Move and relocate applications and data over distance.
● Migrate data faster between data centers.
● Alleviate heavy I/O to a specific storage volume that was originally configured with a large number of extents.
● Retire a storage volume.
● Relocate a "hot" device from slower to faster storage.
Data mobility workflow
1. Launch the appropriate wizard to create and start the mobility job.
2. Monitor the status of the job through completion.
3. Once completed, commit the job to complete the operation and move the data.
4. Remove the record of the mobility job (optional).
Types of data mobility operations
● Device — Moves data from one device to another device (within a cluster or across clusters).
● Batch — Groups extent or device mobility jobs into a batch job, which is then executed as a single job. The GUI does
not support batch mobility jobs. To create a batch mobility job, use the CLI. See the CLI Guide for metro nodefor more
information.
