1. A method of data storage resource access on a network device, the method comprising:
receiving data allocation information on how network traffic processor data is distributed across a plurality of data storage resources in the network device;
connecting a set of direct memory access channels to the plurality of data storage resources based on the received data allocation information, wherein a given data storage resource in the plurality of data storage resources is connected to multiple direct memory access channels in the set of direct memory access channels; and
receiving host commands for accessing the plurality of data storage resources using the set of direct memory access channels, wherein the data allocation information on how the network traffic processor data is distributed across the plurality of data storage resources comprises:
expected data allocation information indicative of an expected data distribution across the plurality of data storage resources, or
types of the received host commands.
