GLB: GitHub's open source load balancer
The article states:>"Each server has a bonded pair of network interfaces, and those interfaces are shared between DPDK and Linux on GLB director servers."What's the distinction between DPDK and Linux here? It wasn't clear to me why SR-IOV is needed in this design. Does DPGK need to "own" the entire NIC device is that? In other words using DPDK and regular kernel networking are mutually exclusive option on the NIC? Is that correct?
