What kinds of environments are not recommended for using Scale-Out?
Applies to
- ONTAP 9
- Server Message Block (SMB 3.x)
- Scale-Out
Answer
Scale-Out is always active in SMB 3.x environments, there are scenarios where it may not function as expected:
- In Hyper-V environments, improper configuration of the Witness protocol or DataLIF placement can prevent clients from reconnecting properly during failover.
- In MPIO configurations, using the “Round Robin with Subset” policy may cause temporary I/O interruptions during node failures. In such cases, the “Failover Only” policy may be more appropriate.
