It’s been a long wait for Part 8 but I was able to release it today! If you are interested on how to network performance test your storage environment this session might help. The purpose of this session is to show how to interconnect two MikroTik switches and ensure their performance is optimal when compared to a single switch. The two NAS devices in this session have different physical capabilities and by no means is this a comparison of their performance. The results are merely data points. Users should work with their vendor of choice to ensure best performance and optimization.
I’ve been building White box PCs since the early 90’s and if you seen my home lab blogs and videos its a passion that has continued on for so many years. When I look for a case, I’m usually looking for practicality and usability as it relates to the indented design. As a DIY home lab builder, using commodity cases is normal but unique cases for home labs are not always easy to find. When I do look for unique Home Lab case ideas, I usually run into lists of the gamer builds that are not so much meant for Home Labs. In this blog I wanted to compile a list of cases that are a bit more unique but someone might want to use for a home lab. For each case, I listed out some of my thoughts around home lab use cases. Of course, deeper research will be needed to determine if they fit your indented use.
USE CASE: Could be used for a stackable home lab or workstations
- ~1U Formfactor | ++ Coolness factor | Portability | Light Weight | Low Noise
- The slide out system tray makes for easy access to internal components, especially when stacked
- Tight form factor limiting options
- Sometimes limited SFX Power Supplies Options
- ITX Standard might be hard for Home Lab deployments
- Limited to 3 Drives
USE CASE: Sure this may look like a standard PC Case, but what’s unique about this case is the MANY ways it can be configured and re-configured. Because of this unique flexibility it would work well as a Workstation or ESXi Host.
- MANY case configurations options
- Want even more space? Look at the Define 7 XL
- Supports ATX and some E-ATX configurations
- Clean case design with 3 Color Options
- Horizontal and vertical PCI Slots
- Wire management
- Air Filters
- 9 Fan Connections
- Lots of Disk space
- No 5.25″ disk bays
- No front facing USB or external ports (all on top)
- It’s big and the XL even bigger
- Some options sold separately
USE CASE: With so many disk options could see this case being used for FreeNAS or even a vSAN cluster
- LOTS of disk space 5 x 3.5 and 1 2.5
- MINI-ITX / Small form factor
- PCI Low Profile slot
- Upright or Lie-down configurations
- Check out the manufacture site for more and similar case designs
- Does require SFX power supply
- The size may limit flexibility
- Only one PCI slot
- No 5.25″ disk bays
With so many 10Gbe Switch options out there for VMware Home Labs I thought I would take some time to create a list of some of the more common options.
Where did I get this data?
William Lam started the VMware Community Homelab project a few years ago. It allows Home Lab users to enter their information around their Home lab. To date the VMware Home Lab community have entered over 125 different VMware Home Labs. When a user registers they provide a URL link which leads to their home lab build-of-materials (BOM) or a description of the users home lab. Its a great resource when you are looking to see what others are doing. This was my primary data source for the results below.
On to the Results!
Over this past weekend, I took some time to review all VMware Community Homelab project links and specifically documented all the folks that noted their 10Gb Switch. I found where 25 users listed the use of a 10Gbe Switch. As I went to each link I documented the switch, its 10Gb Port count, who made it, the model, a current price, and a helpful link.
Here are the TOP 3 most popular and a curious switch:
#1 – With a user count of 7 the Ubiquity Unifi US-16-XG was the most used switch by a single model. Additionally, I noticed many of their other products in users home labs.
#2 – MikroTik with a user count of 8 across 4 different models. Their products are know to be very cost effective for 10Gbe so its no wonder they are in the top 3.
#3 – Our surprise result with a user count of 4 across 2 models is Netgear. But, its no surprise that Netgear has been making great home lab products for decades and they seem to be a bit popular in this 10Gbe arena.
Lastly, a curious switch I noted was the Brocade Communications BR-VDX6720-24-R VDX 6720. With 24 Ports of SFP+ 10Gbe its got me curious why you can find these on Ebay for ~$150. This is one switch I’ll have to look into.
This table contains to total results and extra information :

Update: Here are a few switches that folks mentioned to me in their comments but were not part of the VMware Community HomeLab listing:
- Brocade icx-6610 ~$200 | 16x10G ports, 2x40G ports, 48x1G
- TP-Link TL-SG3428XMP $600 | 24xPOE 1G + 4xSFP+
- Netgear XS508M $600 | 8 x 10Gbe RJ45 1 x shared SFP+
- Ubiquity USW-Pro-Aggregation $899 | Layer 3 switch with (28) 10G SFP+ ports and (4) 25G SFP28 ports.
- Ubiquity USW-Aggregation $270 | L2 8x 10Gb SFP+
- Dell S4112T $1500-$5000 | Multi-function Rack Switch See docs
- D-LINK DX-1210-10TS $1200 | 8 x 10Gbe RJ50 2 x 10Gbe SFP+
- Dell X4012 ~$500-1500 | 12 x 10Gbe SFP+
It was a bit of a surprise the the following switch vendors were not mentioned by users: Linksys, Aruba (now HPE), Juniper, and Extreme Networks.
For a really good list of Network Switch and Router vendors check out this wiki page.
Lastly, it should be noted, there is a another way for Home lab users to enter their BOMs. Most recently a VMware fling known as Solution Designer is allowing Home lab users to enter their data. Here is a quick description of the new service:
The Solution Designer Fling provides a platform to manage custom VMware solutions. Building a custom VMware solution involves many challenging tasks. One of the most difficult is continuous manual verifications: checking the interoperability of multiple VMware products and performing compatible hardware validations. Solution Designer seeks to resolve these issues by automating repetitive manual steps and collecting scattered resources in a single platform.
Note: The only downside to this fling is you can only see your data and not others.
To sum it up, I’m sure this table is less then 100% accurate when it comes to VMware Home Labs. In viewing the listings on the VMware Community Home lab project, I found many dead user links and incomplete BOMs. The list above is more about how many folks are using which switch vs. the specifics of the switch. The specifics are something you might want to review at a deeper level. However, its a good start and the table above should come in handy if you are looking to compare some common 10Gbe switches for your home lab.
Thanks for reading and if I missed your switch, please do comment below and I’ll be glad to add it!
In this Quick NAS Topic video I go over how to install VirutalHere USB Server on the LOCKERSTOR 10 and its client on my Windows 10 PC. This enables the client to establish a link to the a USB NULL Model Cable which is connected directly into the NAS. Once established I’m able to use putty to create a serial SSH connection.

In this Quick NAS Topic video and the steps further below, I use docker to create a ubuntu container with Linux tools and iperf3.
This video is a supplement for the 10Gbe Home NAS Lab Part 7. In Part 7 I show how to use these containers to network performance test the 3 NAS devices I have.
- Create your own Docker Account – https://hub.docker.com/signup
- My Docker Repository – https://hub.docker.com/u/vmexplorer
- A Blog around using a Docker Image that has Iperf3 but limits you to server mode only.
Docker Ubuntu/iperf3 Basic Steps: Items in-between [ ] and the brackets should be removed
- On the NAS:
- Ensure devices can access the inet OR not covered in this blog, you’ll need to manually import and export images, etc.
- Ensure Docker-ce and if needed Shell-in-a-box and portainer are installed and basic configuration is done. The Synology didn’t need shell in a box or portainter
- Test Docker Install
- docker -v << Shows the version
- docker images << Show the images that are available
- docker ps << Shows the running containers
- Elevate local privileges to run docker commands
- It may be necessary to use ‘sudo’ in front of docker commands to get them to execute, followed by the admin/root password. Example: sudo docker ps
- Download and run Ubuntu
- docker pull ubuntu << Image is located here https://hub.docker.com/_/ubuntu
- docker run -it ubuntu bash << Creates an instance of this image for us to modify and opens up the terminal
- Update the Ubuntu running container
- apt-get -y update
- apt-get install iproute2
- apt-get install net-tools
- apt-get install iputils
- apt-get install iputils-ping
- apt-get install -y iperf3
- Test with ping and iperf3 -v
- Do not exit
- Commit and push the new image
- docker ps -l << Check for the latest running container, and note the Container ID of the container that was just updated with these steps
- docker commit [Container ID] [repository name]/[insert-container-name]
- docker images << will validate that the image is now there
- docker push [repository name]/[Container you want to push]
- Testing Steps
- Check Product Interoperability Matrix (VCSA, ESXi, NSX, vRNI, VRLI)
- Check VMware Compatibility Guide (Network Cards, JBOD)
- Ensure the vSAN Cluster is in a health state
- Backup VM’s
- Ensure your passwords are updated
- Document Basic Host settings (Network, vmks, NTP, etc.)
- Backup VCSA via the Management Console > Backup
- NOTE: I used /n software SFTP server to receive backup files
Steps to update vCenter Server from 7U2d (7.0.2.00500) to 7U3a (7.0.3.00100):
- Downloaded VCSA 7U3a VMware-vCenter-Server-Appliance-7.0.3.00100-18778458-patch-FP.iso
- Use WinSCP to connect to an ESXi host and upload the update/patch to vSAN ISO-Images Folder
- Mount the ISO from step 1 to VCSA 7U2d VM
- NOTE: A reboot of the VCSA my be necessary for it to recognize the attached ISO
- Went to VCSA Management Console > Update > Check Updates should auto-start
- NOTE: It might fail to find the ISO. If so, choose CD ROM to detect the ISO
- Expanded the Version > Run Pre-Update checks
- Once it passed pre-checks, choose Stage and Install > Accept the Terms > Next
- Check ‘I have backed up vCenter Server…’
- NOTE: Clicking on ‘go to Backup’ will Exit out and you’ll have to start over
- Click Finish and allow it to complete
- Once done log back into the Management console > Summary and validate the Version
- Lastly, detach the datastore ISO, I simple choose ‘Client Device’
Change Boot USB to SSD and upgrade to ESXi 7U3 on Host at a time:
- Remove Host from NSX-T Manager (Follow these steps)
- In vCenter Server
- Put Host 1 in Maintenance Mode Ensure Accessibility (better if you can evacuate all data | run pre-check validation)
- Shut down the host
- Remove Host from Inventory (NOTE: Wait for host to go to not responding first)
- On the HOST
- Precautionary step – Turn off the power supply on the host, helps with the onboard management ability to detect changes
- Remove the old USB boot device
- Install Dell HBA330 and M.2/NVMe PCIe Card w/ 240GB SSD into the Host
- Power On the Host and validate firmware is updated (Mobo, Disk, Network, etc.)
- Here is how I updated the Dell HBA330 Firmware (SEE VIDEO HERE)
- During boot ensure the Dell HBA330 POST screen displays (optional hit CTRL-C to view its options)
- In the Host BIOS Update the boot disk to the new SSD Card
- ESXi Install
- Boot the host to ESXi 7.0U3 ISO (I used SuperMicro Virtual Media to boot from)
- Install ESXi to the SSD Card, Remove ISO, Reboot
- Update Host boot order in BIOS for the SSD Card and boot host
- In the ESXi DUCI, configure host with correct IPv4/VLAN, DNS, Host Name, enable SSH/Shell, disable IPv6 and reboot
- From this ESXi host and from another connected device, validate you can ping the Host IP and its DNS name
- Add Host to the Datacenter (not vSAN Cluster)
- Ensure Host is in Maintenance mode and validate health
- Erase all partitions on vSAN Devices (Host > Configure > Storage Devices > Select devices > Erase Partitions)
- Rename the new SSD datastore (Storage > R-Click on datastore > Rename)
- Add Host to Cluster (but do not add to vSAN)
- Add Host to vDS Networking, could be multiple vDS switches (Networking > Target vDS > Add Manage Hosts > Add Hosts > Migrate VMKernel)
- Complete the Host configuration settings (NTP, vmks)
- Create vSAN Disk Groups (Cluster > Configure > vSAN > Disk Management)
- Monitor and allow to complete, vSAN Replication Objects (Cluster > Monitor > vSAN > Resyncing Objects)
- Extract a new Host Profile and use it to build out the other hosts in the cluster
- ESXi Install – Additional Hosts
- Repeat Steps 1, 2, 3, and only Steps 4.1-4.10
- Attach Host Profile created in Step 4.15
- Check Host Profile Compliance
- Edit and update Host Customizations
- Remediate the host (the remediation will to a pre-check too)
- Optional validate host settings
- Exit Host from Maintenance mode
- Before starting next host ensure vSAN Resyncing Objects is completed
Other Notes / Thoughts:Host Profiles: You may be thinking “why didn’t he use ESXi Backup/Restore or Host Profiles to simply this migration vs. doing all these steps?”. Actually, at first I did try both but they didn’t work due to the add/changes of PCIe devices and upgrade of the ESXi OS. Backup/Restore and Host Profiles really like things to not change for them to work with out error. Now there are adjustments one could make and I tried to adjust them but in the end I wasn’t able to get them to adjust to the new hosts. They were just the wrong tool for the first part of this job. However, Host Profiles did work well post installation after all the changes were made. vSAN Erase Partitions Step 4.8: This step can be optional it just depends on the environment. In-fact I skipped this step on the last host and vSAN imported the disks with out issue. Granted most of my vm’s are powered off, which means the vSAN replicas are not changing. In an environment where there are a lot of powered on VM’s vSAN doing step 4.8 might be best. Again, it just depends on the environment state. If you like my ‘no-nonsense’ videos and blogs that get straight to the point… then post a comment or let me know… Else, I’ll start posting really boring content!
In this quick video I review how I updated the Dell HBA330 firmware using a Windows 10 PC.
This video was made as a supplement to my 2 Part blog post around updating my Home Lab Generation 7.
In this not so Quick NAS topic I cover how to expand a RAID 1 volume and migrate it to a RAID 5 storage pool with the Synology 1621+. Along the way we find a disk that has some bad sectors, run an extended test and then finalize the migration.

Well its that time of year again, time to deploy new changes, upgrades, and add some new hardware. I’ll be updating my ESXi hosts and vCenter Server to the latest vSphere 7 Update 3a from 7U2d. Additionally, I’ll be swapping out the IBM 5210 JBOD for a Dell HBA330+ and lastly I’ll change my boot device to a more reliable and persistent disk. I have 3 x ESXi hosts with VSAN, vDS switches, and NSX-T. If you want to better understand my environment a bit better check out this page on my blog. In this 2 part blog I’ll go through the steps I took to update my home lab and some of the rational behind it.
There are two main parts to the blog:
- Part 1 – Change Rational for software and hardware changes – In this part I’ll explain some of my thoughts around why I’m making these software and hardware changes.
- Part 2 – Installation and Upgrade Steps – These are the high level steps I took to change and upgrade my Home lab
Part 1 – Change Rational for software and hardware changes:
There are three key changes that I plan to make to my environment:
- One – Update to vSphere 7U3a
- vSphere 7U3 has brought many new changes to vSphere including many needed features updates to vCenter server and ESXi. Additionally, there have been serval important bug fixes and corrections that vSphere 7U3 and 7U3a will address. For more information on the updates with vSphere 7U3 please see the “vSphere 7 Update 3 – What’s New” by Bob Plankers. For even more information check out the release notes.
- Part of my rational in upgrading is to prepare to talk with my customers around the benefits of this update. I always test out the latest updates on Workstation first then migrate those learnings in to Home Lab.
- Two – Change out the IBM 5210 JBOD
- The IBM 5210 JBOD is a carry over component from my vSphere 6.x vSAN environment. It worked well with vSphere 6.x and 7U1. However, starting in 7U2 it started to exhibit stuck IO issues and the occasional PSOD. This card was only certified with vSphere/vSAN 6.x and at some point the cache module became a requirement. My choices at this point are to update this controller with a cache module (~$50 each) and hope it works better or make a change. In this case I decided to make a change to the Dell HBA330 (~$70 each). The HBA330 is a JBOD controller that Dell pretty much worked with VMware to create for vSAN. It is on the vSphere/vSAN 7U3 HCL and should have a long life there too. Additionally, the HBA330 edge connectors (Mini SAS SFF-8643) line up with the my existing SAS break-out cables. When I compare the benefits of the Dell HBA330 to upgrading the cache module for the IBM 5210 the HBA330 was the clear choice. The trick is finding a HBA330 that is cost effective and comes with a full sized slot cover. Its a bit tricky but you can find them on eBay, just have to look a bit harder.
- Three – Change my boot disk
- Last September-2021, VMware announced boot from USB is going to change and customers were advised to plan ahead for these upcoming changes. My current hosts are using cheap SanDisk USB 64GB memory sticks. Its something I would never recommend for a production environment, but for a Home Lab these worked okay. I originally chose them during my Home Lab Gen 5 updates as I need to do testing with USB booted Hosts. Now that VMware has deprecated support for USB/SD devices it’s time to make a change. Point of clarity: the word deprecated can mean different things to different people. However, in the software industry deprecated means “discourage the use of (something, such as a software product) in favor of a newer or better alternative”. vSphere 7 is in a deprecated mode when it comes to USB/SD booted hosts, they are still supported, and customers are highly advised to plan ahead. As of this writing, legacy (legacy is a fancy word for vSphere.NEXT) USB hosts will require a persistent disk and eventually (Long Term Supported) USB/SD booted hosts will no longer be supported. Customers should seek guidance from VMware when making these changes.
- The requirement to be in a “Long Term Supported” mode is to have a ESXi host be booted from HDD, SSD, or a PCIe device. In my case, I didn’t want to add more disks to my system and chose to go with a PCIe SSD/NVMe card. I chose this PCIe device that will support M.2 (SATA SSD) and NMVe devices in one slot and I decided to go with a Kingston A400 240G Internal SSD M.2 as my boot disk. The A400 with 240GB should be more than enough to boot the ESXi hosts and keep up with its disk demands going forward.
Final thoughts and a important warning. Making changes that affect your current environment are never easy but are sometimes necessary. With a little planning it can make the journey a bit easier. I’ll be testing these changes over the next few months and will post up if issues occur. However, a bit of warning – adding new devices to an environment can directly impact your ability to migrate or upgrade your hosts. Due to the hardware decisions I have made a direct ESXi upgrade is not possible and I’ll have to back out my current hosts from vCenter Server plus other software and do a new installation. However, those details and more will be in Part 2 – Installation and Upgrade Steps.
Opportunity for vendor improvement – If backup vendors like Synology, asustor, Veeam, Veritas, naviko, and Arcoins could really shine. If they could backup and restore a ESXi host to dislike hardware or boot disks this would be a huge improvement for VI Admin, especially when they have tens of thousands of hosts the need to change from their USB to persistent disks. This is not a new ask, VI admins have been asking for this option for years, now maybe these companies will listen as many users and their hosts are going to be affected by these upcoming requirements.
During this Quick NAS Topic I review how to install and test a supported USB WiFi Network device into the DRIVESTOR 2 Pro.
