Kernel-level SMB3 for Linux?

[AveryFreeman]

Hi,

kind of an odd question - I know SMB3 is being touted as a VM datastore-worthy transfer protocol on Windows Server platforms with RDMA / SR-IOV capabilities, etc. but is the same thing available for Linux? Do I understand it in that 'Samba' for Linux is a userland-only protocol and doesn't perform kernel-level IO operations like Windows and Solaris, or is there a kernel-level SMB equivalent available for Linux that is comparable to the Windows version in terms of IOPs?

Thanks!

Samba server v4 has some basic support for smb3, but no rdma features (Samba3/SMB2 - SambaWiki).

I don't know if kernel vs user space iops would make a difference, I think that pcie/sas/sata latency is higher than the time the samba server needs for processsing requests, but I'm not a linux system developer so this can be wrong.
