Environment

Live migration or protection of Windows and Linux workload
PlateSpin Protect 10.x and above
PlateSpin Forge 3.x and above
PlateSpin Migrate 9.x and above

Situation

Windows/ Linux source workload being live migrated with Platespin Migrate or protected with Platespin Protect/Forge is running an application (database) which has a high transaction rate resulting in high disk IO. The migration/sync job of such workload will fail or not complete for extremely long period.

Resolution

It is recommended to keep disk IO low on source workload during migration/sync job. In rare situation, it may require stopping the application/services responsible for such high IO on source temporarily while sync job runs.

Cause

This is a limitation of Platespin block-based driver and the behavior is by design. The driver cannot handle a very high rate of changes to disk blocks.
