DPDK and Open vSwitch Installation on Debian 10

DPDK stands for Data Plane Development Kit. The DPDK project consists of libraries to accelerate packet processing workloads running on a wide variety of CPU architectures. Open vSwitch can use the DPDK library to operate entirely in userspace. Thanks to it, performance of Open vSwitch increases. The tutorial help you to build and install Open vSwitch using DPDK datapah on Debian 10 Buster. The second part discuses DPDK and Open vSwitch configuration and compare performance of Open vSwitch applicance with enabled/disabled DPDK.

Note: You can download my Debian 10 Buster VMDK image with installed DPDK 18.11.2 and Open vSwitch 2.11.1 for quick testiing of Open vSwitch/DPDK functionality. If you do so, you can skip the tutorial and continue with Part 2 - DPDK/Open vSwitch Configuration.

Ampere preps an 80-core Arm processor for the cloud

Ampere Computing, the semiconductor startup led by former Intel president Renee James that designs Arm-based server processors, is preparing to launch its next-generation CPU by mid-2020.The upcoming chip will have 80 cores, much more than the 32-core processor the company shipped last year and vastly more than x86 CPUs by Intel and AMD. Ampere’s design is different. Instead of multiple threads per core, each core is single threaded.[Get regularly scheduled insights by signing up for Network World newsletters.] Jeff Wittich, Ampere’s senior vice president of products, said that was by design, to avoid some of the CPU vulnerabilities that crept into x86 chips but also to avoid the “noisy neighbor” problem in cloud service-provider networks.To read this article in full, please click here

You Still Need a Networking Engineer for a Successful Cloud Deployment

You’ve probably heard cloudy evangelists telling CIOs how they won’t need the infrastructure engineers once they move their workloads into a public cloud. As always, whatever sounds too good to be true usually is. Compute resources in public clouds still need to be managed, someone still needs to measure application performance, and backups won’t happen by themselves.

Even more important (for networking engineers), network requirements don’t change just because you decided to use someone else’s computers:
