Multi-tenancy requirements

Server and Cluster Administration Guide for Hitachi NAS Platform

Part Number

Requirements for enabling and using multi-tenancy mode.

In order to enable and use multi-tenancy mode, the following requirements must be met:

  • The per-EVS security license must be installed.
  • All EVSs present on the NAS server or cluster must be configured with individual security settings.

    If you want to convert a NAS server to use multi-tenancy, contact technical support.

  • An EVS may use a VLAN interface, or an aggregation interface, but VLANs configured with the vlan command are not supported. VLAN interfaces are configured using the vlan-interfaces command.

    Scripts are available to convert the VLANs to VLAN interfaces, but these scripts should not be used without technical support guidance.

    Note: When multiple EVSs are used for a tenant, no policing of ag interface or VLAN interface usage is performed. The NAS server administrator must ensure that EVSs for different tenants do not use the same network interface. If EVSs for different tenants do use the same interface, traffic for one tenant could be seen on a different tenant's network (this situation would be no different than if a switch was configured incorrectly).
  • No cluster name space (CNS) may be configured (an EVS name space is supported).
  • Active Directory Server (ADS) entries must be used instead of NT domains.
    Note: When multi-tenancy is enabled, NetBIOS is disabled and NT4 domains cannot be used.
  • For clusters, all nodes must be running a version of software that supports multi-tenancy
  • When enabling multi-tenancy mode for a cluster, all cluster nodes must be online.
