Quota Considerations
1. For NAS volumes with mixed security styles, a unique quota must be set for both the
Windows (Active Directory) users and UNIX (LDAP or NIS) users. The quotas for the
Windows and UNIX user will be independent of each other even if the users are
mapped (automatically or manually).
2. For NAS volumes with NTFS or UNIX style permissions, only one unique quota must
be set. User mapping functionality handles cross protocol interoperability. The UNIX
and Windows user shares the same quota for both Windows and UNIX accounts that
are mapped.
3. In general, mixed security style is not recommended. It is recommended to use NTFS
in mixed environments.
