Example embodiments relate to protocol agnostic storage access with a software defined network (SDN). A method may include receiving, at a SDN enabled switch, an initialization packet to access a storage volume. The method may include determining, at the SDN enabled switch, a storage protocol used by the initialization packet, adding a protocol tag indicative of the storage protocol to the initialization packet, and sending the initialization packet to a SDN controller. The method may include identifying, at the SDN controller, a storage application based on the protocol tag and sending the initialization packet to the storage application. The storage application may be one of a plurality of storage applications, each associated with a different storage protocol. The method may include performing, by the storage application, protocol-specific tasks.
