User and Group Quotas
The following table lists the maximum number of supported quota rules per NAS volume for each system.
Table 13. Supported Quota Configurations
Feature Maximum per System
Quota rules 1024
Quota usage entries 100,000
Quota directories 30,000
NOTE:
• Quotas for Active Directory (AD) and NIS/LDAP users are independent of each other, even if users are mapped
automatically or manually. For NAS volumes with mixed security styles, separate quotas should be set for AD and
NIS/LDAP users.
• For NAS volumes with NTFS or UNIX style permissions, one unique quota should be set for each user. For mapped
users, the usage and limits are applied using the target identity and are shared with the native Windows or UNIX
account.
• In general, Dell recommends using the NTFS security style in mixed environments.
