transmitting the second partial request to the second storage node.

11. The non-transitory computer-readable medium of claim 8 , further comprising program code executable by the processor for causing the processor to transmit the request to the storage node for:

subsequent to transmitting the request to the storage node, determining the storage node includes the data of the request; and

12. The non-transitory computer-readable medium of claim 8 , further comprising program code executable by the processor for causing the processor to:

receive the request from a queue of a plurality of requests for data operations; and

send the one or more parameters of the request to a ring buffer accessible by the second path of the smart NIC.

13. The non-transitory computer-readable medium of claim 12 , wherein the request is a first request and the routing information is first routing information, and further comprising program code executable by the processor for causing the processor to:

perform, by the first path, a first operation associated with the first request substantially contemporaneously with a second operation for a second request, wherein the first operation comprises:

receiving the first request from the queue; and

sending the first request to the second path, and

wherein the second operation comprises:

receiving second routing information for the second request from the second path;
