Supermicro Home Lab Group Buy

by // 35 Comments

Happy New Years everyone! I was supposed to get this out right before the holidays but #babylam got really sick and I had to put this on hold.

Back in November I threw out an idea on Twitter to see if the #vCommunity would be interested in doing a group buy for some Supermicro kits, especially for those looking to upgrade their personal home labs to take advantage of all the new VMware goodies such as vSAN, NSX and PKS for example.

Within minutes, I had several dozen replies and it was clear that folks were definitely interested in refreshing their lab, especially with a smaller and more modern platform. Over the last few weeks, I have been working with MITXPC (who I have worked with before) on putting together some packages that would appeal to the majority of the community. Initially, I was thinking about three options: system-only (no memory/storage), system with memory (no storage) and system with memory and storage. To be clear, system means complete chassis with CPU and motherboard included. Please see the product links below for more details.

Is a DNS server still required when using a Static IP for VCSA?

by // 7 Comments

When deploying a vCenter Server Appliance (VCSA), customers have two options for setting up a static network address: using either a hostname (Fully Qualified Domain Name) or just a static IP Address (e.g. no DNS). In the first option when using an FQDN, it should be no surprise that you need to also specify a valid DNS Server which the VCSA UI/CLI Installer will automatically validate both the forward and reverse address. This is the most common deployment model for customers in both production as well as for development environments such as a vSphere home lab.

In the second scenario, where a static IP Address is used, a DNS server is not required because we are NOT using an FQDN for the hostname but rather an IP Address. Having said that, if you have ever used the VCSA UI or CLI, you will find that the DNS Server entry is actually a required field and you can not proceed without providing an address.

VCSA UI Installer:

VCSA CLI Installer:

"network": {
    "ip_family": "ipv4",
    "mode": "static",
    "ip": "192.168.30.151",
    "dns_servers": [
        "192.168.30.1"
    ],
    "prefix": "24",
    "gateway": "192.168.30.1",
    "system_name": "192.168.30.151"
}

As mentioned earlier, we know that it should not be required but currently the VCSA Installer is a bit overly cautious in its pre-checks and does require a value today. This is something that has already been shared internally and the team will be relaxing this requirement in the future.

With that said, this leads us back to the original question posed in the blog title, do we need a valid DNS server when using a static IP for the VCSA?

1,000th post - The story behind virtuallyGhetto

by // 11 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 🙂
