Dear Community,
Since ONTAP 9.4 [1] there is this new CIFS option "-max-credits" with a default of 128.
According to Microsoft [2] on Windows Servers this defaults to 8192.
The basic of SMB Credits as far as I know is, the server grants the client x-amount of credits, which the client can spend for requests to the server. By limiting the credits it should be possible to cap rouge clients. But how does this work?
What does the configured credit amount actually mean?
Is this for a specific timeframe? Is the amount for each client or for the whole Server?
Will the server grant the credits on client request? What does affect the grant of these credits?
How can this be monitored?
How to find out, if the configured max-credits are too high or too low?
Why has MS set the default to 8192 and NetApp only to 128?
Best regards
Oliver
