The next traditional version (five-year mainstream, five-year extended support) of Windows Server became generally available (GA) in October at Ignite US. But because this skipped the traditional release-to-manufacturing (RTM) step, hardware manufacturers still needed to test and validate their server hardware. So this blocked some features (like Storage Spaces Direct) from installation ... DPDK is a software acceleration technique comprised of a software library and drivers which reduce CPU overhead caused by interrupts sent each time a new packet arrives for processing. Instead, DPDK implements a polling process for new packets with a key benefit of significantly improving processing performance while eliminating PCI overhead and Oct 06, 2020 · DPDK needs poll mode drivers to operate. Poll mode drivers are shared objects in /usr/lib64. See the full list of supported NICs at dpdk.org NICs. You must know which kernel module each NIC is using and choose a poll mode driver that corresponds to your NICs.
