its common practice these days to disable SMB 1.0 for both security and performance reasons.
Having done this on a Windows 2012R2 server I find that I am unable to connect this server to the DXIv1000 via CIFS filesystem. A neighboring 2012R2 server with SMB 1.0 enabled is able to connect to the DXI.
Is it possible to use the DXI in an environment where SMB 1.0 has been disabled?
The only solution I have so far is to use NFS, which you can use on Windows Server 2012R2 with the mount command and NFS client feature installed.
Also note that if you are using SMB for file sharing among Windows machines, disabling SMB 1.0 on either the client or server makes file transfers about twice as fast. Its well worth disabling it if not only for security reasons!
Hopefully they will fix this, it'll probably improve throughput to the DXI.
Seeing that the DXI v1000 is on the 2.3.x.x firmware the workaround is to either switch to NFS or move the CIFS shares to a workgroup. If the CIFS shares are moved to workgroup then Quantum support can modify a file to remove smb1, however, this would require a support contract on the DXi v1000 to accomplish.
