Hello Wolfi,  That is correct , currently VNXe does not support Quotas but you should be able to use Windows Quotas for your requirement but again all troubleshooting for this will have to initiated from Windows end EMC will not be able to help with that.
 Hi,   IHAC who has 2 VNXe1350s for CIFS (so Shared Folders) purposes only. Now he was not necessarily delighted when i told him that VNXe neither supports quota trees nor user quotas. I have guided him how to create Shares on subfolders that he had previously created and how to get to the Windows quota Management tab after mounting the root of a given filesystem (e.g. \\cifs-server\users$ to drive z:\) to a host in order to Limit the space for the users' homedrives. He hated it since their users' help desk Needs to script Standard procedures like creating a new user's homedirectory and Setting a quota for it.   Now the question: is the Windows GUI just the vehicle through which i have to define user quotas b/c UEMCLI and VNXe Unisphere don't provide means to do so, but the actual quota will be defined on the VNXe somewhere? I haven't found anything in the Manuals referring to user quotas, so since there is no command to do anything in this regard. So i'm assuming that the VNXe just is agnostic towards quotas and they will have to define a process that keeps quota Management and Information outside the storage that's carrying the filesystems that a being quoted.   right?   thanks in advance for any hint.   Wolfi
