An ode to joy – or why you don’t have to mourn the free ESXi

by

An ode to joy, or why you don’t have to mourn the free ESXi. An obituary.

But before I go into depth here, I would like to declare the following:

This blog post is reflecting my personal opinion. Based on my knowledge and experience, as well as the things I have read on the internet and heard from people directly and discussed with them, I have written this blog post.

The title of this blog post says a lot. At least I think so. And I’m glad you stumbled across this blog post or clicked the link wherever it has been posted. In the last few days, there has been a lot of reading about the fact that VMware by Broadcom has canceled the free ESXi hypervisor. And yes, that may not be the fine English way to mash such a product. I don’t even know if there is a “good” way to do something like that.

Yes. It’s bad that the “free ESXi” has been canceled. At least according to what I read about on X (Twitter) and some IT news portals. People were (and still are) angry about this move of thinning out the product portfolio. I never used this free version, and I wasn’t even aware that this was such a big thing. But that doesn’t count here.

Yes. There are alternative hypervisors, like Hyper-V, Proxmox, and others, and they are free. You can run virtual machines even on storage systems like TrueNAS or Unraid (the last one does cost some bucks). And a free hypervisor, I don’t care about the flavor, might be just enough for some people. They may run a homelab with some VMs, maybe some production services for their home network like Pi-Hole, to name one.

But this is it.

vExpert Applications are open

by

The vExpert applications for 2024 are open now. Nice! But what is this?

Some vendors have special programs for the IT folks around the world. These programs are designed for ambassadors and evangelists. Microsoft with its MVP, Veeam with the Vanguards, and many more.

As benefits, you may get early access to beta versions, marketing information, they help you promote your blog posts and many other great things. The VMware vExpert program is VMware’s global evangelism and advocacy program.

There is no certification exam for becoming a vExpert, no course requirement. It is kind of an award or an accreditation. You have to apply for the vExpert program, and a committee will review your application, and then accept your application or reject it.

Do I have what it takes?

Yes! The vExpert program is about “giving back”. You work in your job, you do great things, and help your users and customers. You’ve got experience in IT technology and working for some years already in that area. You may work at VMware, at a partner, or you may be a VMware customer.

Giving back means sharing your knowledge. Did you fix a problem? Blog about it! Did you set up a new solution for a customer? You may speak about it at VMworld! If you’re not a writer, then there are various groups on social media, or you can find forums like the VMTN (and many other non VMware related forums). There are a lot of users, both partners, and customers, asking for help. Help them with your experience and knowledge! You may have written a book about VMware solutions, or you’re focusing on a specific VMware product. Maybe you are a public speaker or a VMUG leader. You have the knowledge, you have experience, share it!

How can I apply?

It is very easy to apply. There are two applications per year. One is starting during the summertime, and one is starting in early December. Both application windows are open for some days. After this period, the committee will close the applications and start their voting. This may take some time too. The results for the December applications are usually announced in February, the summer application will be announced somewhen in August.

If you’re already a vExpert or even a VCDX, you have to reapply. There are also vExpert sub-programs, like Application Modernization, HCX, Cloud Management, and many others, that you can apply for if you’ve been awarded a vExpert.

The December vExpert applications are open now, and the results will be announced in February 2024 (my guess). And it might be one of the most eagerly awaited emails, at least if you read about it on some blogs, or see it popping up on Twitter.

Click here to apply for vExpert 2024!

Can I get help?

Yes! VMware announced the vExpert PRO program. There are more than 100 vExpert PROs around the world that are helping you. They can help you with mentoring, tell you what you have to do, and outline the process of the applications. Just reach out to the vExpert PRO close to your area!

What benefits can I get from the vExpert program?

If you check the list on the vExpert website, you can see that there are a lot of benefits. I’m not listing every point here, but I’d like to mention at least some of them.

You will be part of a global network roughly 1600 other vExperts. They are on social media, Twitter, active on blogs and forums. There is also a Slack channel for vExperts. You’ll get a certificate signed by the VMware CEO. One of my personal favorites is the access to 365 day eval licenses for most of the VMware products, like vSphere, vSAN, etc. Throughout the year, you got the opportunity to join private webinars with VMware partners. You will be featured on the vExpert Directory. Also before VMware Explorer (former VMworld), there are pre-launch briefings for bloggers, which means that you may get a sneak peek at some products or announcements. Also, at the VMware Explore event, there will be vExpert parties both in the US and Europe locations. And I tell you, these parties are awesome!

My personal view

I’m working for about 23 years in IT now, including my apprenticeship. I learned many things, and I’m still learning. I had the chance to gain insights into different industries during my work. When I was awarded a vExpert for the first time, I felt honored. It meant a lot to me to be one of only a few hundred to receive such an award. It showed also that my efforts are worth it, and that they have been noticed. I was working on a partner level for many years, helped my customers to build their infrastructure, helped them with troubleshooting. Now, I’m working at a customer, fighting with daily business problems, architecting data centers, migrating workloads, and designing cloud concepts. I just recently applied to a new job and switched my focus from managing datacenters to managing VMware Horizon VDI workloads. But I still have strong bounds to the datacenter, as I am an infrastrucutre guy, and will ever be an infrastructure guy.

Some people kept smiling at my vExpert status because they didn’t believe in certifications, accreditations, etc. But that didn’t bother me. I did my thing. I wrote blog posts, and I still write (even if not as often or regularly as I want). I’m active in forums and help people with troubleshooting. And I’ve always stood up for one thing. I’m grateful for becoming a vExpert, it meant a lot to me, and it still does.

Personally, I have the feeling that, especially in contact with technical support, it enables a different level of communication if the other person recognizes my status as vExpert. A problem may escalate upwards faster, and you may have faster access to 3rd level support. Things like this. But also during projects, when I’m in contact with internal customers and external consultants, they recognize my status and see that I’m not just some random IT technician or IT dude. I know some stuff, I’m experienced, and someone voted for me so I could become a vExpert. As mentioned, it’s not a certification exam you can learn for. It is the personal commitment that shines through here.

How to create custom (storage) reports on your Synology NAS

by

The vExperts had the chance to attend an exclusive online session recently together with Synology. The topic was “Flexible VM backup and recovery solutions with Synology”. Josue Guzman, Technical Account Manager at Synology, showed us how to set up and use the VM backup solution. He demoed also the whole backup and restore process. And especially the instant restore option, where the Synology NAS mounts itself as an NFS datastore into your ESXi host was awesome.

Many thanks to Corey Romero and the vExpert team for organizing all these cool sessions!

But I’m not going to recap the session here. I just want to pick up the thread because there is a not-inconsiderable amount of space required with backup. And if you also have specific RTO and RPO that have to hold data for a certain period of time, then the storage requirement can be quite large.

And that’s exactly the thread I want to pick up. When you’re working with Synology NAS systems, you may know how cumbersome it sometimes is to get the size of the various (shared) folders you have on your NAS. Sure, you can do “right-click => select Properties” on every folder, note it down somewhere, and then you can add all the values together. But who wants that?

But there is a much nicer and more elegant way to get the folder size. And at the end, you even see colored pie charts. Well, are you curious now?

How to remove a host from a vSAN cluster

by

This blog post, I call blog posts like these “quick & dirty posts”, will show you today how to remove an ESXi host permanently from your vSAN cluster. Yes. Permanently. Forever.

Usually, you’re adding more capacity to a cluster, which means adding more hosts or disks to solve that problem. However, some legitimate reasons exist to remove an ESXi host from a vSAN cluster. Maybe you’re currently in the middle of a hardware renewal. The new hardware is already installed and running in production. And now, server by server, you’re removing the old hardware because you’re on track with the workload migration. The same counts for adding a cluster with nodes that have more “meat by the bone”, more compute power, and storage capacity. Nodes that are running more energy-efficient than the old ones. You see, only two reasons, but there might be many more.

But let’s dive into this topic now.

How to remove an ESXi host from a vSAN cluster?

We’re starting with making sure that the cluster and the disk groups have enough space to have one host removed. If the cluster is fine, let’s move on to remove the host.

Place the host into maintenance mode

Right-click the host, choose “Maintenance Mode”, then “Enter Maintenance Mode”.

How to add a new host to a vSAN cluster

by

This blog post, I call blog posts like these “quick & dirty posts”, will show you today how to add an ESXi host to your vSAN cluster. You may need additional compute power, and/or storage capacity. Or you want to implement another storage policy to leverage storage efficiency and more failures to tolerate (RAID 5 / RAID 6 erasure coding). Maybe you want to create a stretched cluster, which needs an even number of vSAN nodes on each side plus a vSAN witness. So many reasons to add another vSAN node.

But let’s dive into this topic now.

How to add a new host to a vSAN cluster?

In my vSAN cluster, based on the Express Storage Architecture (ESA), I’ve got six hosts currently. I want to add another host to the cluster because of the computing and storage power. How to do this?

Right-click your cluster and choose “Add Hosts…”. So far, nothing special.
