1. A computer-implemented method, comprising:
receiving a request for adding a target controlling unit into a processing system, the target controlling unit configured to provide physical processing resources to the processing system, and the processing system including at least one processor, a storage area network connected to the at least one processor, and a controller connected to the storage area network that includes at least one controlling unit;
in response to receiving the request, dividing, by one or more processors, a plurality of network nodes in the storage area network into a group of subnets based on a topology of the plurality of network nodes, the plurality of network nodes being connected to the at least one controlling unit in the processing system;
determining, by the one or more processors, a workload estimation for each subnet of the group of subnets that is to be caused by adding the target controlling unit to the processing system; and
removing, by the one or more processors, an unqualified subnet from the group of subnets to form an updated group of subnets, the unqualified subnet including at least one hot node having a traffic estimation above a predefined traffic threshold when the target controlling unit is connected to the unqualified subnet.
