Data center network with packet spraying

A system comprising:

• a plurality of network devices, including a source network device and a destination network device;
• a switch fabric comprising a plurality of core switches;
• a destination access node coupled to the switch fabric and at least the destination network device;
• and
• a source access node coupled to the switch fabric and at least the source network device, wherein the source access node is configured to provide network accessible storage for use by an application executing on one of the plurality of network devices, and wherein the source access node is configured to:
• enable establishment of a logical tunnel over a plurality of data paths across the switch fabric between the source access node and the destination access node, and
• spray a data flow of packets, received from the source network device, over the logical tunnel to the destination access node, wherein to spray the data flow of packets, the source access node directs each of the packets within the data flow to one of the data paths based on an amount of data previously transmitted on each of the plurality of data paths.
