1,000th post – The story behind virtuallyGhetto

by 6 Comments


After publishing my previous article, I realized my next blog post (this article) would be number 1,000, which is pretty insane! It has been an amazing 8 years of sharing and engaging with the VMware community and I just want to thank everyone that has supported me over the years.

Although I have a number of technical blog posts in the backlog, I thought I might do something fun and different for post #1,000. One question that I have gotten over the years, especially when talking to customers and partners in-person is, what is the story behind the name of my blog, virtuallyGhetto? I sometimes even get funny looks as customers are introducing me to their colleagues and management team when they mention the name of my blog 🙂

Learning more about the Nitro platform which will power VMware Cloud on AWS Outposts

by Leave a Comment

With the big announcement last week between AWS and VMware, I know a number of folks have been wanting to learn more about the underlying hardware that currently powers the AWS Cloud including VMware Cloud on AWS and eventually the new VMware Cloud on AWS Outposts offering. Historically, AWS has not shared much information about their own hardware platform, but have started to talk more openly about their systems in the last two years.

At reInvent 2018, I had attended an awesome deep dive session Powering Next-Gen EC2 Instances: Deep Dive into the Nitro System by Anthony Liguori, a Sr. Principal Engineer who lead both the Nitro and Outposts development. This was a great talk providing some insights into the development of Nitro and the various components that makeup the system such as the Nitro cards, which provides hardware offload for both Storage and Networking and new in this years session, the Nitro Security Chip, which actually reminds me of the new Apple T2 Security Chip. Below is the recording for those that were not able to attend, definitely recommend a watch!

VMware Cloud on AWS reInvent sessions posted

by Leave a Comment

In case you missed the big news this week at Amazon's reInvent conference, Pat Gelsinger (CEO of VMware) and Andy Jassy (CEO of AWS) announced together on stage VMware Cloud on AWS Outposts and VMware Cloud Foundation for EC2. For more details regarding the announcements, check out these two blog posts:

VMware had a number of VMware Cloud on AWS (VMC) sessions at reInvent and most of them have already been posted online. Below is the current list and I will update it as new sessions are posted.

Given the amount of excitement and interests from customers on both VMware Cloud on AWS Outposts and VMware Cloud Foundation for EC2, session (ENT215) was repeated at reInvent to give some more information about the two solutions. In addition, you can also check out these two theCube interviews from each of our executives talking about both offerings.

Supermicro E300-9D (SYS-E300-9D-8CN8TP) is a nice ESXi & vSAN kit

by 10 Comments

Supermicro kits such as the E200-8D is a very popular platform amongst the VMware community and with powerful Xeon-based CPUs and support for up to 128GB of memory, it is perfect for running a killer vSphere/vSAN setup!

Earlier this Fall, Supermicro released a "big daddy" version to the E200-8D, dubbed E300-9D and specifically, I want to focus on the 8-Core model (SYS-E300-9D-8CNTP) as this system actually listed on the VMware HCL for ESXi! The E300-9D can support up to half a terabyte of memory and with the 8-Core model, you have access to 16 threads. The E200-8D is also a supported platform by VMware, you can find the VMware HCL listing here.


I was very fortunate to get my hands on a loaner E300-9D (8-Core) unit, thanks to Eric and his team at MITXPC, a local bay area shop specializing in embedded solutions. In fact, they even provided a nice vGhetto promo discount code for my readers awhile back, so definitely check it out if you are in the market for a new lab. As an aside, when doing a quick search online, they also seem to be the only ones actually selling the E300-9D (8-Core) system which you can find here and in general, they seem to be priced fairly competitively. This is not an endorsement for MITXPC, but recommend folks to compare all prices when shopping online, especially as today is Black Friday in the US and Cyber Monday is just a few days away.

Can a VM in the VMC Compute Network access the SDDC Management Network?

by Leave a Comment

Similiar to an on-premises vSphere deployment, VMware Cloud on AWS follows good security practices by isolating and preventing access to the SDDC Management Network including Virtual Machines running in the Compute Network. With that said, the SDDC can be configured to enable access to the SDDC Management Network for either all or subset of workloads running in the Compute Network.

I have seen this request come up a few times, usually around proof of concepts, lack of on-premises infrastructure or wanting to run completely isolated within VMC for Dev/Test purposes. Below are the step by step instruction on setting this up for both an NSX-V and NSX-T based SDDC. Once enabled, customers can access the vCenter vSphere UI from within the specified Virtual Machine(s) including using tools like OVFTool or PowerCLI for importing new or existing workloads.

Note: Please refer to this blog post here to determine if you are running an NSX-V or NSX-T based SDDC.

Heads Up – Apple Mac Pro 6,1 fails to boot after upgrading to ESXi 6.7 Update 1

by 4 Comments

We had a number of customers report that after upgrading their Apple Mac Pro 6,1 to the latest ESXi 6.7 Update 1 release, the system failed to boot and the following error was seen on the console:

Shutting down firmware services...
Mutiboot buffer is too small.
Unrecoverable error

A few customers made the observation that this was in result of a newer version of the Apple Firmware that was included in the Mac Pro 6,1 systems which seemed to have cause this problem. In addition, this also impacts brand new installations of ESXi 6.7 Update 1 on new Mac Pro 6,1 that includes a newer version of the Firmware. At this time, is it NOT recommended to upgrade to ESXi 6.7 Update 1 if you are running the Mac Pro 6,1. A request has already been made to the VMware HCL team to remove Mac Pro 6,1 for ESXi 6.7 Update 1 and hopefully should be reflected by later this evening.

Note: This issue can also affect the Apple Mac Mini, which is not an officially supported platform for ESXi.

In the mean time, VMware has published KB 59660 which provides a workaround that may help customers who have upgraded their Mac Pro 6,1 to ESXi 6.7 Update 1 to rollback to the previously installed version of ESXi. Please refer to the KB for more details and you can subscribe to the article for future updates regarding this issue.
