The Network Collective crew—Jordan, Eyvonne, and I—will be at Cisco Live this week. You can normally find me hanging around the certifications or social media lounge, or just walking around the floor talking to folks. I’m presenting at the CCDE techtorial on Sunday.
NSX Data Center has shown for some time now (see VMworld 2016 NSX Performane Session (NET 8030) that it can drive upwards of 100G of throughput per node for typical data center workloads. In that VMworld session, we ran a live demo showing the throughput being limited by the actual physical ports on the host, which were 2 x 40 Gbps, and not by NSX Data Center.
Typically, in physical networking, performance is measured in raw packets per seconds to assure variety of traffic at variable packet sizes be forwarded between multiple physical ports. While in virtualized data center this is not a case, as hypervisor hosts only have to satisfy few uplinks, typically no more than four physical links. In addition, most of the virtualized workload use TCP protocol. In that case. ESXi hypervisor fowards the TCP data segments in highly optimized way, thus not always based on number of packets transferred but the amount of data segment forwarded in software. In typical data center workloads, TCP optimizations such as TSO, LRO and RSS or Rx/Tx Filters help drive sufficient throughput at hardly any CPU cost. TSO/LRO help move large amounts of Continue reading
The initial release of the SevOne SD-WAN Monitoring software will give insights into Cisco-Viptela SD-WAN environments, but it will soon be extended to support other SD-WAN vendors.
Severalnines has spent the last several years writing blogs and crafting content to help make your open source database solutions highly available. We are fans of highscalability.com and wanted to post some links to our top resources to help readers learn more how to make MySQL, MongoDB, MariaDB, Percona and PostgreSQL databases scalable.
The Full Stack Engineer’s Guide to Network Programmability with Python will provide learners with an inductive and comprehensive introduction to the Python programming language to include the various data types, control flow structures, functions, methods, classes, objects, reading and writing files, data storage using MySQL, and regular expressions. We will also cover on- and off-box Python automation and explore the guest shell in IOS-XE!
White box beat Dell EMC in terms of data center server revenue and units shipped in the first quarter of 2018.
The Linux Foundation Executive Director Jim Zemlin acknowledges that there are “still small pockets of deep mistrust of Microsoft in the open source community.”
One trial used the OIF's FlexEthernet client interface standard, the other was based on Ciena's WaveLogic Ai platform.
The BT executive just last month announced plans to slash 13,000 jobs as part of a broader corporate restructuring. Investors were not happy.
Verizon debuts software-defined secure branch; Microsoft takes data centers underwater; and T-Mobile, Nokia complete 5G data session.
Juniper Appformix is a telemetry platform thats multi-vendor, cross layer, built-in machine learning and
with fancy visualisation. Its designed simplify operations and closed-loop automation. In the era of multi-cloud, we need tools that run on-prem or in cloud and support OpenStack, K8s, VMware, Azure, Google, Amazon networks with integration into virtual machines, containers, overlay networks and physical devices.
The ability to draw data from a wide range of sources creates data flood that can overwhelm you. Appformix has machine learning and a range of automation functions to simplify and organise this diverse data flood. The increasing complexity of networks as the the edge of the network expands in multiple dimensions – on and off premises, virtual edge, overlay networks as well the physical devices must all operate in cahoots.
Appformix is automating this operational load so you aren’t getting calls at 2am. Thats a very fine thing.
Sumeet Singh, VP/GM for Juniper AppFormix, kicks off the discussion with a quick intro to Appformix, we cover the key features and the approach of the product before we move into use cases and what customers are using today. Surprisingly, this includes WAN operations in addition to DC/Cloud.
Hey, it's HighScalability time:
Slovenia. A gorgeous place to break your leg. Highly recommended.
Do you like this sort of Stuff? Please lend me your support on Patreon. It would mean a great deal to me. And if you know anyone looking for a simple book that uses lots of pictures and lots of examples to explain the cloud, then please recommend my new book: Explain the Cloud Like I'm 10. They'll love you even more.
Savvius’ suite of packet monitoring technology will be integrated with LiveAction’s monitoring platforms to give a more complete view into network environments.
