Three-stage cost-efficient disaggregation for high-performance computation, high-capacity storage with online expansion flexibility

A method comprising:

• assigning, by a network switch, a minimal bandwidth allowance for each of a plurality of traffic routes in a disaggregated network, the disaggregated network comprising a plurality of compute nodes, storage heads, and storage devices;
• weighting, by the network switch, each traffic route based on a traffic route priority;
• monitoring, by the network switch, a current bandwidth utilized by the disaggregated network;
• distributing, by the network switch, future packets according to the weighting if the current bandwidth is indicative of a low or average workload;
• and
• guaranteeing, by the network switch, minimal bandwidth for a subset of the traffic routes if the current bandwidth is indicative of a high workload, the subset of traffic routes selected based on the origin or destination of the route comprising a compute node.
