1. An information processing system that includes a plurality of nodes having a processor and a storage device, the information processing system comprising:
a storage configured to process data that a node cluster receives from or outputs to the storage device; and
a management unit including a physical port and configured to manage the storage,
the storage, and the management unit operating on the processor,
wherein the management unit is configured to create a tenant and assign the node cluster and a resource of the storage to the tenant,
each node cluster including a different logical initiator port logically associated with the node cluster that uses the physical port of the management unit,
tenant information related to the tenant is associated with the initiator port used by the respective node cluster assigned to the tenant, and
the management unit is configured to determine the tenant to which the node cluster is assigned from an ID of the initiator port of the node cluster when an access request is issued from the node cluster, and
determine whether access from the node cluster to the storage is possible based on the tenant to which the resource of the storage and the node cluster are assigned and permit or prohibit the access.
