Technology Short Take #46

Welcome to Technology Short Take #46. That’s right, it’s time for yet another collection of links and articles from around the Internet on various data center-related technologies, products, projects, and efforts. As always, there is no rhyme or reason to my collection; this is just a glimpse into what I’ve seen over the past few weeks. I hope you are able to glean something useful.

Setting up the Tools for Contributing to OpenStack Documentation

For non-programmers, making a meaningful contribution to an open source project can be difficult; this is as true for OpenStack as for other open source projects. Documentation is a way to contribute, but in the case of OpenStack there is a non-trivial setup required in order to be able to contribute to the OpenStack documentation. In this post, I’m going to share how to set up the tools to contribute to OpenStack documentation in the hopes that it will help others get past the “barrier to entry” that currently exists.

Learning NSX, Part 18: Routing Without Network Address Translation

This is part 18 of the Learning NSX blog series, in which I talk about using layer 3 (L3) routing with VMware NSX but without network address translation (NAT). This post describes a configuration that offers yet another connectivity option for OpenStack cloud administrators and operators.

Learning NSX, Part 17: Adding External L2 Connectivity

This is part 17 of the Learning NSX blog series. In this post, I’ll show you how to add layer 2 (L2) connectivity to your NSX environment, and how to leverage that L2 connectivity in an NSX-powered OpenStack implementation. This will allow you, as an operator of an NSX-powered OpenStack cloud, to offer L2/bridged connectivity to your tenants as an additional option.

Multi-Machine Vagrant with YAML

In this post, I’ll describe a technique I found for simplifying the use of multi-machine Vagrantfiles by extracting configuration data into a separate YAML file. This technique is by no means something that I invented or created, so I can’t take any credit whatsoever; this is an idea I first saw here. I wanted to share it here in the hopes that it might prove useful to a larger audience.

Questions for Photography Enthusiasts

It’s no secret that I’m something of a photography enthusiast. To me, photography is a relaxing puzzle of how to assemble all the various pieces—setting, lighting, exposure, composition, etc.—to create just the right image. I’m not an expert, but that’s OK; I just do this for fun and to relax. If you’d like to see a small sampling of some of the photos I’ve taken, I publish some of them here on 500px.com.

Learning NSX, Part 16: Routing to Multiple External VLANs

This is part 16 of the Learning NSX series, in which I will show you how to configure VMware NSX to route to multiple external VLANs. This configuration will allow you to have logical routers that could be uplinked to any of the external VLANs, providing additional flexibility for consumers of NSX logical networks.

Thinking About Intel Rack-Scale Architecture

You may have heard of Intel Rack-Scale Architecture (RSA), a new approach to designing data center hardware. This is an idea that was discussed extensively a couple of weeks ago at Intel Developer Forum (IDF) 2014 in San Francisco, which I had the opportunity to attend. (Disclaimer: Intel paid my travel and hotel expenses to attend IDF.)
