Hands on with new AMD “NUC” platform from ASRock

11/16/2019 by William Lam 3 Comments

It has been rumored for some time now that AMD would be re-entering the embedded/small form factor (SFF) market and with their latest generation of Ryzen CPUs, timing could not be more perfect. With the rise of Edge and IoT workloads, new constraints like cost, footprint, low to no tech-touch and power consumption is now top of mind more than ever for customers.

At VMware, we certainly see interests from customers across this spectrum whether it is a traditional "ROBO" environment running a handful of Virtual Machines for a supermarket or retail chain to an industrial site such as an oil rig or factory to mobile infrastructure like a car, ship or even a submarine. On top of these use cases, personal and development labs continue to be extremely popular amongst our customer base for learning and training purposes.

Today, the Intel NUC is still by far the most popular platform due to its size, portability, cost and low power consumption for running VMware vSphere, vSAN & NSX. The idea of an AMD "NUC" kit which includes a chassis, motherboard and CPU is something that that many folks have been asking for. With the market mostly dominated by Intel, I certainly welcome AMD re-entering this market as this will certainly drive new solutions and innovations in this market. With that said, AMD has re-entered into this market and this is initially through partnerships with several OEMs/manufacturers.

Podcasts I listen to

11/12/2019 by William Lam 2 Comments

In many of my conversations with customers, partners and colleague at this past VMworld, various topics about VMware software and solutions came up as you would expect. However, there were also many other topics that were discussed such as career, education, kids, tv shows, movies and podcasts.

One question that kept coming up over and over was around which podcasts I listen to on a regular basis? Like most, I listen to podcasts to help past the time while commuting into work, especially with our lovely Bay Area traffic. I also try to use this time as an opopournity to expose myself to other things happening outside of our immediate industry whether that is Bio, Retail, Healthcare, Economics, etc. I always enjoy learning about new things, especially the stories and innovations on how certain companies or things came to be, which is always super fascinating is usually the result of being passionate and having perseverance. Below are the podcasts that I listen to on a regular basis, a few like Worklife, Serverless Chats, Command-Line Heroes and TED Talks are recent ones which I have added and have only listening to a handful of episodes but they seem interesting so far.

I am also curious if there are other podcasts folks from the community would recommend? If so, please leave a comment as I am always on the look out for new shows!

VMworld EU 2019 officially wrapped up 45min ago (as of writing this) and this was another amazing VMworld. I really enjoyed all the great conversations from customers, partners and fellow VMware colleagues. Although many of us are running around the entire week for sessions and meetings, we certainly appreciate it when folks stop us and just hi or even ask for a picture.

I also want to personally thank everyone who attended my sessions and hopefully you got something out of it. Please consider leaving feedback on the VMworld Survey on what you enjoyed and things that we can improve upon for future VMworlds. Now that I am officially done, I figure I would have a beer and do some quick scripting.

Simliar to VMworld US, the VMworld team has already processed and published a number of recordings! Similar to past years, I have put together a nice summary page that contains all the session recordings links separated out by the different categories which you can find by visiting http://vmwa.re/vmworld2019.

Customizing the NSX-T Login UI

10/29/2019 by William Lam Leave a Comment

I have been doing some automation with NSX-T 2.5 lately and for troubleshooting and validation purposes, I obviously make use of the NSX-T UI. After each new deployment I need to login to verify a few things. Out of pure laziness, I really would like to be able to login with just a single click for development purposes. I certainly could use password manager but it would still be a couple of clicks but I was looking something slightly quicker and that could easily work in a number of environments that I have.

Looking around the filesystem of the NSX Unified Appliance, I found the structure for the login UI to be fairly similiar (thanks to VMware Clarity) to that of the vCenter Server Appliance (VCSA). I found that I could apply the same techniques I had used to customize the VCSA Login UI including setting up pre-filled credentials (no recommended for obvious reasons) on the NSX-T Appliance.

How to debug NSX-T API Automation with PowerCLI?

10/25/2019 by William Lam Leave a Comment

I recently needed to deploy the latest version of NSX-T (2.5) for some work I was doing with Project Pacific and of course it was related to Automation 🙂 It has been some time since I have touched the NSX-T Manager API (2.0) and although most of my existing code still worked, there were some things that broke due to API deprecation and also net new functionality that I needed to use.

I normally use PowerCLI for my Automation work and/or for prototyping purposes, not only is it easy to do but PowerCLI is still one of the most popular tool used by our customers and it means that they can easily benefit from my work. However, one of my pet peeves when working with the NSX-T APIs and PowerCLI is simply the lack of useful error messages. Here is the generic error message that you would normally see even checking the $Error[0].Exception.ServerError variable, it generally does not contain anything useful or actionable.

A server error occurred: 'com.vmware.vapi.std.errors.invalid_request': . Check $Error[0].Exception.ServerError for more details.

Here is a concrete example where I am attempting to create a new Transport Zone but I am purposing leaving out a required parameter and as you can see from the output, the same generic error message is shown and not very actionable.

I normally debug NSX-T API issue whether it is a syntax or usage problem by SSH'ing to the NSX-T Manager and monitoring the actual API logs to figure out what is actually going. It usually has exactly what I am looking for in terms of the actual server error message along with details on how to fix the problem.

Automate disabling @channel & @here notifications using private Slack API

10/17/2019 by William Lam Leave a Comment

Slack is a popular communication and collaboration tool which has been adopted by many organizations including the one I work for. I am a fan of Slack and use it on a regular basis. Like most users, I am a member of several different workspaces and a ton of different channels.

I think most Slack users would agree that one of the most commonly miss-used feature of Slack is the @channel and @here notifications which allows a user to broadcast a message that notifies everyone within a specific channel. I most often see this when a user is looking for immediate assistance and think that this is the best way to get help, it is not. In some cases, inpatient uses end up spamming multiple channels which can have up to 1K+ members! As you can imagine, this type of behavior is usually not well received.

This is the modern day "reply-all" email storms that I am sure many of you have at experienced at least once if not many more times within your organization 🙂 Slack does provide a few ways of disabling notification, either within the workspace but this would disable the feature completely and I do see value in this feature when used correctly or disabling notifications on a per-channel basis as shown in the screenshot below.
