enabling smb3

Question

Currently we only run SMB versions 1/2 in our Isilon environment, i'm not sure why smb3 was not enabled by default. what are the consequences of turning on  'Support Smb3 Encryption' ? would that cause issues to windows 10/11 clients? my understanding is windows systems will attempt to negotiate to the highest SMB version and will failover to the lower one if there is an issue.  i did not notice any interruption in connectivty on our simulator and it seems pretty simple to enable/disable smb3 if required, is there meant to be any downtime expected with this?

Hi, Thanks for your question. What version of OneFS are you using? It shouldn’t create any disruption to enable it. Let us know if you have any additional questions.
