Protecting Workloads with Global Network Backing Using Site Recovery Manager

Many thanks to Dimitri Desmidt from VMware, NSBU for providing the Design details of Multi-Location and Federation.

Preface

Starting NSX-T version 3.0.2 workloads with NSX-T global network backing (L2 stretched segment) can be protected and recovered using Site Recovery Manager (SRM). More details on Multi-Locations with Federation are available here.

Note: This post does not contain the installation and configuration details of NSX-T federation, vSphere Replication and Site Recovery Manager. Hence, it is necessary to meet the following pre-requisite to achieve the goal of protecting workloads with global segments using SRM.

Pre-requisite

  • Understanding of NSX-T Federation and its configuration is necessary.
  • Understanding the installation and configuration of vSphere Replication and Site Recovery Manager (SRM) is necessary.

Limitations

SRM is not currently supported with Federation with VM Tags, Segment Ports, or Segment Ports Tags. As mentioned in the Design Guide for Multi-Locations here:

  • Currently recovered VMs via SRM does not recover their NSX VM Tags.
  • Recovered VMs will receive new Segment Ports on the new LM.
  • If the Federation Security is based on VM Tags, Segment Ports or Segment Ports Tags then the recovered compute VMs in another location (London in our example here) do not have their Continue reading

Give The Network Designer That Came Before You A Break

When you take over a network as a technical lead, you often run into design elements that make you do a spit-take. They did WHAT? Really? Were they...stupid? Clueless? Stupid AND clueless? Maybe they were, but I argue that you should give those humans that came before you a break. You weren't there. You don't know what constraints they were operating under. Since you don't know those things, it's hard to pass fair judgement. Unfair judgement? Oh, yeah. All day long, and you can even feel righteous while doing so. Super smug.

Understanding GNS3 Appliances – Video

The labbing tool GNS3 has a capability called “appliances” but it may not mean what you think it means. GNS3 co-founder and developer Jeremy Grossman and networking instructor David Bombal talk with Ethan Banks about what appliances mean in the context of this software. You can listen to the full episode, “Heavy Networking 556: The […]

Tech Bytes: SD-WAN Helps Medical Imaging Company Get The Picture Faster (Sponsored)

This Tech Bytes podcast explores how SimonMed, a medical imaging company, turned to an SD-WAN deployment from Silver Peak to reduce image delivery time from minutes to seconds, improve performance of VoIP, and begin a migration from expensive MPLS circuits.

Who Shoulders the Supercomputing Resiliency Burden?

While the related topics of fault tolerance and resiliency do not garner the same attention as performance and efficiency, being able to recover from and work around failures, especially as applications take over ever-large and increasingly heterogenous machines, is more important than ever. …

Using Velero to Protect Cluster API

Cluster API (also known as CAPI) is, as you may already know, an effort within the upstream Kubernetes community to apply Kubernetes-style APIs to cluster lifecycle management—in short, to use Kubernetes to manage the lifecycle of Kubernetes clusters. If you’re unfamiliar with CAPI, I’d encourage you to check out my introduction to Cluster API before proceeding. In this post, I’m going to show you how to use Velero (formerly Heptio Ark) to backup and restore Cluster API objects so as to protect your organization against an unrecoverable issue on your Cluster API management cluster.

To be honest, this process is so straightforward it almost doesn’t need to be explained. In general, the process for backing up the CAPI management cluster looks like this:

  1. Pause CAPI reconciliation on the management cluster.
  2. Back up the CAPI resources.
  3. Resume CAPI reconciliation.

In the event of catastrophic failure, the recovery process looks like this:

  1. Restore from backup onto another management cluster.
  2. Resume CAPI reconciliation.

Let’s look at these steps in a bit more detail.

Pausing and Resuming Reconciliation

The process for pausing and resuming reconciliation of CAPI resources is outlined in this separate blog post. To summarize that post here for convenience, the Cluster Continue reading

Webinars in 2021

After deciding to take a slightly longer coffee break I went through the list of outstanding projects trying to figure out which ones I could complete in first half of 2021, which ones I’ll get to “eventually” and what’s a lost cause.

Guest Speakers

Irena is telling me that I should stop inviting guest speakers – our calendar is full until June 2021. Here’s what we have planned and what we got done at the time of the last update (January 30, 2021).

The Week in Internet News: U.K. Investigating Google Chrome’s Privacy Push

No more cookies: Google’s Chrome browser has announced a plan to replace tracking cookies with a system that shares less information with advertisers, but the U.K.’s Competition and Markets Authority is worried that more user privacy would have a “significant impact” on news websites and on the digital advertising market, the BBC reports. The agency has warned that publishers’ profits could drop if they no longer run personalized advertisements.

A vulgar display of content: The Chinese National Office Against Pornographic and Illegal Publications has fined short video app Douyin, a sister app to TikTok, for spreading “obscene, pornographic and vulgar information,” the South China Morning Post says. The app was fined “tens of thousands of yuan,” the regulator said. Regulators said they received more than 900 reports related to pornographic and vulgar content on Douyin in the past year.

The sports car Internet: Gigabit Internet service is coming to rural Kansas and Missouri with funding from the Federal Communications Commission’s Rural Digital Opportunity Fund, FlatlandKC.org reports. The site compared gigabit speeds to a fast sports car. The FCC has selected 180 winning bidders to receive $9.2 billion in funding to provide increased Internet access to 5.2 million Continue reading

Save the Date for DockerCon Live 2021!

Untangling Compliance: Working Toward a Global Framework

Untangling Compliance: Working Toward a Global Framework

As part of Cloudflare’s recent Privacy Week we hosted a series of fireside chats on security, privacy, and compliance. Many of these conversations touched on the intricate legal debate being held in Europe around data sovereignty. Here are some of the highlights.

To learn more about the solutions Cloudflare launched to help businesses navigate their compliance needs — including the new data localization suite — see our recent blog post here.

Untangling Compliance: Working Toward a Global Framework

We have to agree to go down a common road, a common path. And this common path can really only consist of saying: let's sit down together again. I'm talking about the European Commission and, above all, the new administration in the United States. We are all waiting for them expectantly.

And then we look at what our common fundamental values are and see if we don’t simply come together better than we have in the past. After all, our fundamental values are the same: human rights, democracy, the rule of law. You have to concede that there are some differences in understanding when it comes to interpreting what privacy means — Continue reading
