cDOT cluster share limit (cifs NFS) 8.3

Patrick-Cui — Wed, 04 Jun 2025 19:59:17 GMT

I've been unable to find out what the limitation of a single Cifs share is on FAS8040, 4 nodes? Also the number of individual files supported?
Can anyone point me in the right direction?

This offical site gave a little information.

This page is good but for different model.

http://community.netapp.com/t5/Network-Storage-Protocols-Discussions/2040-CIFs-maximums/td-p/60328

the cifs limits of the fas2040 are
Max nr. of connections = 44'000
Max nr. of shares = 88'000
Max nr. of share connections = 176'000
Max nr. of open files = 880'000
Max nr. of locked files = 970'112
Max nr. of locks = 1'940'224

I am not aware of any protocol related limit on number of files in a volume. There is max directory size and theoretical limit on number of files in a volume. The latter is derived from the minimal file size of 4K; and max directory size can be increased in principle (although not recommended).

Thanks for response. There do has limition of # of filer - 31.88m - I foudn it, however, my question is regarding how many concurrent connections to the CIFS share, locked files, opened files and so on. For sure, as the hardware is limited, the supported # of clients is not unlimited.

For windows server - filer, we can simply run a command to have the number, net config server, the output like this,
