About Multitenancy
Multitenancy enables a single physical FluidFS cluster to be partitioned into several separate service entities (tenants) and manage
each one individually. FluidFS v6 supports up to 100 tenants. When multitenancy is enabled, the user interface is optimized and
includes the tenants view.
Network connections – Each tenant utilizes exclusive IP addresses (virtual IPs). Users who have access to the tenant’s VIP can
only see that tenant’s NFS exports, SMB shares, and so on.
Authentication and user repositories – Each tenant utilizes its own authentication and user repositories. Each tenant can dene
and use the following settings:
• DNS conguration – The DNS conguration of the default tenant serves the cluster services (such as NTP).
• Active Directory – Each tenant can join a dierent Active Directory. Two tenants can also join the same Active Directory (with
separate tenant computer objects in Active Directory).
• LDAP or NIS
• Local users and groups
• User mapping
Reusing of same name in dierent tenants – Multitenancy supports using the same SMB share name and the same local user or
group name.
Volume Replication – Administrators can dene between which tenants volume replication is allowed.
Managing tenants – FluidFS v6 adds a new type of administrator called tenant administrators. A tenant administrator has the ability
to:
• See (but not update) all of the general cluster settings
• Manage tenants they have been granted Tenant Administrator access to, including all the NAS volumes that belong to those
tenants
• Receive email events that are relevant to the entire cluster and to the tenants they have been granted Tenant Administrator
access to, such as power-down events
Using Multitenancy With Existing Features
Multitenancy interoperates with the following existing FluidFS features:
Antivirus – SMB shares are isolated to their tenant. If any shares have antivirus enabled, they utilize the virus scanners that are
dened at the clusterwide level.
