Data migration and namespace management across domains in multi-domain clustered file systems

A method of providing load balancing in a multi-domain network to affect sustainability goals, comprising:

• partitioning a clustered network into a number of separate domains, wherein each domain contains resources including processors, memory, storage devices, as well as data deduplication and compression services;
• presenting a single global namespace for the network is presented to a user or backup process by combining all of the namespaces in the domains;
• monitoring environmental operating conditions of each node in the clustered network;
• detecting nodes having operating conditions exceeding defined tolerances;
• and
• providing a multi-domain manager component having a load balancer to migrate data and processes from nodes exceeding the defined tolerances to other nodes not exceeding the defined tolerances.

A system for migrating data and balancing loads in a multi-domain network, comprising:

• a clustered network partitioned into a number of separate domains, wherein each domain contains resources including processors, memory, storage devices, as well as data deduplication and compression services;
• a single global namespace for the network presented to a user or backup process by combining all of the namespaces in the domains;
• a multi-domain manager component having an analytics engine to facilitate analytics-driven migration of data among nodes in different domains;
• and
• a load balancer component monitoring environmental operating conditions of each node in the clustered network, detecting nodes having operating conditions exceeding defined tolerances, and migrating data and processes from nodes exceeding the defined tolerances to other nodes not exceeding the defined tolerances.
