Abstract
A method, computer program product, and computer system for maintaining a federation of a plurality of appliances as a single subsystem, wherein maintaining the federation as the single subsystem may include maintaining a centralized discovery mechanism across the plurality of appliances, wherein a discovery service of the centralized discovery mechanism may return a list of all ports in the federation. Controller IDs for a predefined range of controller IDs may be allocated for a plurality of dynamic controllers per appliance of the plurality of appliances, wherein the controller IDs may be allocated as a response to a connect command from a host. An empty namespace list for the plurality of dynamic controllers on the plurality of appliances in the federation may be exposed. The host may receive a notification from at least one dynamic controller of the plurality of dynamic controllers on at least one appliance of the plurality of appliances in the federation. The host may obtain a list of namespaces hosted on the at least one appliance corresponding to the at least one dynamic controller.
