The Immigrating dashboard let you visualize the top 20 most frequently migrated VM the last 7 days (manual, initiated by DRS or “self” vmotion – aka Storage vMotion Fast Suspend/Resume). If a cluster is heavily loaded or if the DRS migration threshold is too aggressive, some VM might be moved very often. Moreover, due to “self” vmotion, fully automated SDRS may also be source of immigrating messages in logs.


According to DRS Performance and Best Practices :

If the loads vary, DRS with a moderate threshold may achieve better throughput in the long run because it would recommend fewer migrations and hence incur a lower VMotion cost compared to DRS with an aggressive threshold.
