Disaster Recovery with VMware NSX-V and Zerto Note, this is a reposting of the blog that I initially posted here on humairahmed.com. In a prior blog, VMware NSX and SRM: Disaster Recovery Overview and Demo, I described and demoed how VMware NSX and SRM with vSphere Replication combined provide for an enhanced disaster recovery (DR) solution.

In episode 10 we look at how to take the first steps towards automating your network. What tools should you use? Should you learn a programming language? And if so, which one? Should you buy or build your automation? Do you need to become a full fledged programmer in addition to being a network engineer? Our excellent panel of guests addresses all of the above and more!

The annual Africa Peering and Interconnection Forum (AfPIF) kicked off at the Azalai Hotel in Abidjan, Ivory Coast.
The first day is known as “Peering Coordinators Day” where peering managers from various networks, operators, and policy makers meet and deliberate on the various ways to exchange content locally, lower the cost of connectivity, and increase the number of internet users in the region.
Having decided it’s time to learn how to code, and having chosen the right language to use, the next step is to find some resources and start programming that masterpiece. But what’s the best way to learn that language?
On the Solarwinds Thwack Geek Speak blog I spoke about how I started learning to code, and look at some of the different resources out there to kickstart your programming mastery. Please do take a trip to Thwack and check out my post, “New Coder: Getting Started and Finding Your Path“.
Please see my Disclosures page for more information about my role as a Solarwinds Ambassador.

Hiding the information from network core is important. But why hiding the information is important ? What type of information we are trying to hide ? Why from network core only ? How we can hide the information from network core ? Let’s start, why information hiding is important. One of the […]

One of the engineers going through my Ansible for Networking Engineers online course sent me this question:
In the Introduction section, you mention a use case of upgrading software. Do you have an example playbook?
Unfortunately, I don’t. Upgrading software is one of those things that’s almost impossible to simulate in a virtual lab.

We’ve already mentioned this a few times this year, but we’ve just published an more in-depth article about NAT64check over on the RIPE Labs and APNIC websites.
NAT64check is a tool developed by the Internet Society, Go6, SJM Steffann and Simply Understand that allows you to enter the URL of a particular website, and then run tests over IPv4, IPv6 and NAT64 in order to check whether the website is actually reachable in each case, whether identical web pages are returned, and whether all the resources such as images, stylesheets and scripts load correctly. The rationale behind NAT64check is also explained, how it works, and how you can use it.
If you just want to take a look at the tool, then please go to either https://nat64check.go6lab.si/ or https://nat64check.ipv6-lab.net/, type the URL you wish to check into the box at the top of the page, and the result should be returned within a few seconds. It’s simple and easy, and will help you identify what needs to be done to make your website accessible with IPv6.
Deploy360 also want to help you deploy IPv6, so please take a look at our Start Here page to learn more.

From day one, Cumulus Networks has always believed in making data center networking easier and better. To us, that never stopped at just an operating system. Our goal has always been to unify the entire stack on Linux and bring web-scale principles to all aspects of the data center networking process — from network to operations; from host to switch. This was one of the many key drivers behind our introduction of NetQ, a fabric validation system designed to make network operator’s lives easier by ensuring the network is behaving as intended. Today, we launch the next critical step in web-scale networking — Cumulus Host Pack.
Host Pack offers software essentials that bring the host into the network. It optimizes visibility and connectivity into Cumulus Linux network fabric from end to end. Your entire stack can now be unified with the same language and the same tooling using the Linux networking model. Host Pack ensures real-time reliability and uptime to the container by leveraging NetQ to enhance visibility of the host. In addition to visibility, Host Pack enhances network scalability and connectivity by enabling the host to be part of the layer 3 network, while completely supporting popular layer 2 Continue reading
By now, VxLAN is becoming the standard way of tunneling in the Datacenter.
Using VxLAN, i will show how to use the CSR1Kv to extend your Datacenter L2 reach between sites as well.
First off, what is VxLAN?
It stands for Virtual Extensible LAN. Basically you have a way of decoupling your vlan’s into a new scheme.
You basically map your VLAN into a VNI (Virtual Network Identifier), which in essence makes your VLAN numbering scheme locally significant.
Also, since the numbering for VNI’s is a 24 bit identifier, you have alot more flexibility than just the regular 4096 definable VLAN’s. (12 Bits .1q tags)
Each endpoint that does the encapsulation/decapsulation is called a VTEP (VxLAN Tunnel EndPoint). In our example this would be CSR3 and CSR5.
After the VxLAN header, the packet is further encapsulated into a UDP packet and forwarded across the network. This is a great solution as it doesnt impose any technical restrictions on the core of the network. Only the VTEPs needs to understand VxLAN (and probably have hardware acceleration for it as well).
Since we wont be using BGP EVPN, we will rely solely on multicasting in the network to establish who is the Continue reading
Make sure to include the network in your data protection planning.
Professor Satoshi Matsuoka, of the Tokyo Institute of Technology (Tokyo Tech) researches and designs large scale supercomputers and similar infrastructures. More recently, he has worked on the convergence of Big Data, machine/deep learning, and AI with traditional HPC, as well as investigating the Post-Moore Technologies towards 2025.
He has designed supercomputers for years and has collaborated on projects involving basic elements for the current and more importantly future Exascale systems. I talked with him recently about his work with the Tsubame supercomputers at Tokyo Tech. This is the first in a two-part article. For background on the Tsubame 3 system …
