VNXe systems do not support stand alone CIFS servers. Along similar lines, you need to have DNS, NTP servers in your environment to be able to setup the system. This is a known customer concern though.
When we use celerra ,there is a stand alone mode with cifs. Is AD a must for VNXe CIFS shares?  In a small enviroment , there is no AD,no NTP,no DNS.Then can VNXe work is this enviroment?
CIFS use stand alone mode
