Network virtualization uses an encapsulation technology for the overlay network. Common encapsulation technologies include GRE, VXLAN, STT, and a promising new technology called Geneve.
Today, we will focus on Stateless Transport Tunnel (STT) and some of the benefits over GRE and VXLAN….
With the growth of network virtualization, it’s time to take a look back at Intel Data Plane Development Kit (DPDK). DPDK provides optimized Packet Processing on Intel® Architectures.
The following homepage and document from Intel® details DPDK capabilities…
VMware has a number of Engineering Tools available called “Flings” built by VMware engineers that are intended to be played with and explored as technical previews or simple diagnostic tools…

Not networking, but a little gotcha that caught me out today with very slow boot times for ESXi V5.5 associated with RDM’s and MSCS configured LUN’s mounted via VPLEX. Details in the following KB article associated with a volume flag called “perennially-reserved”… http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1016106
Throughput testing over 10 GbE has been an interesting exercise and Virtual Machines using the VMXNET3 adapter achieve impressive throughput while maintaining complete mobility around a VMware Cluster (vMotion/HA/DRS).
The following series of tests validate throughput when using VM’s configured to use SR-IOV…
