Access zones best practices

You can avoid configuration problems on the PowerScale cluster when creating access zones by following best practices guidelines.

Best practice Details
Create unique base directories. To achieve data isolation, the base directory path of each access zone should be unique and should not overlap or be nested inside the base directory of another access zone. Overlapping is allowed, but should only be used if your workflows require shared data.
Separate the function of the System zone from other access zones. Reserve the System zone for configuration access, and create additional zones for data access. Move current data out of the System zone and into a new access zone.
Create access zones to isolate data access for different clients or users. Do not create access zones if a workflow requires data sharing between different classes of clients or users.
Assign only one authentication provider of each type to each access zone. An access zone is limited to a single Active Directory provider; however, OneFS allows multiple LDAP, NIS, and file authentication providers in each access zone. It is recommended that you assign only one type of each provider per access zone in order to simplify administration.
Avoid overlapping UID or GID ranges for authentication providers in the same access zone. The potential for zone access conflicts is slight but possible if overlapping UIDs/GIDs are present in the same access zone.
