My Journey from Infrastructure Admin to Cloud Architect: Understanding vSAN Fault Domains

As an infrastructure admin, I have always been fascinated by the underlying technology that powers our virtualized environment. Recently, I had the opportunity to delve deeper into vSAN and its concepts, specifically the Fault Domain (FD) concept. In this blog post, I will share my journey of understanding vSAN FDs and how they can be used to protect our cluster against rack or site failures.

What are Fault Domains in vSAN?

In vSAN, a Fault Domain (FD) is a grouping of hosts that provides protection against a rack or site failure. Each FD can have one or more ESXi hosts, and usually, it is used to protect the cluster against a single rack or site failure. vSAN will never place components of the same object in the same FD. If the whole FD fails (e.g., a top-of-rack switch failure or a site disconnection), we will still have a majority of votes for the object to be available.

The Smallest Fault Domain is the Host Itself

If we don’t configure any FD in vCenter, every ESXi host will become a kind of FD, because we will never have components of the same object on the same host… even if the host has more than one disk group. So, the smallest FD is the host itself.

Protecting against Rack Failures

In vSAN, the smallest number of FDs required to protect against a single rack failure is 3. To achieve this, we can place two ESXi hosts per rack and have five FDs in total (3x VMDK + 2x witness). With this configuration, we can ensure that even if one rack fails, the other racks will still be available to provide access to our virtual machines.

Using Fault Domains for Protection

To protect against two rack failures, we can use a mirroring policy with FTT=2. This requires five FDs (3x VMDK + 2x witness). With this configuration, we can ensure that even if two racks fail, the other racks will still be available to provide access to our virtual machines.

Another important aspect to consider is that vSAN distributes components automatically, so the concept of FD might be a way to influence where the components are placed. For example, if we have five racks and ten ESXi hosts, we could place two hosts per rack and use FDs to protect against rack failures.

Stretched Clusters for Additional Protection

In some cases, it may be desirable to protect against a single rack failure using a stretched cluster concept. In this approach, vSAN will think of Rack 1 as a Preferred Site and Rack 2 as a Secondary Site, and will use Primary Failures To Tolerate of 1 to mirror components between those “sites.” This provides an additional layer of protection against rack failures.

Witness Host for Split Brain Scenario

When using a stretched cluster, it is essential to have a witness host that is hosted outside or on a standalone tower host that does not require a third rack. This witness host will protect the cluster against a split brain scenario.

Conclusion

In conclusion, Fault Domains are an essential concept in vSAN that provide protection against rack or site failures. Understanding how to configure FDs and use them for protection is crucial for any infrastructure admin or cloud architect. By using FDs, we can ensure that our virtual machines remain available even in the event of a failure. Additionally, stretched clusters and witness hosts can provide additional layers of protection against rack failures.

Troubleshooting vRealize Orchestrator Authentication Issues with vCO-App Containers

As a VMware vRealize Automation and Orchestrator expert, I recently encountered an issue while attempting to change some settings on several instances of vRealize Orchestrator embedded within vRealize Automation 8.8.1 appliances. Specifically, I was unable to successfully authenticate to the vRealize Orchestrator Control Center interface using the “root” user credentials. Although I could authenticate to the virtual appliance consoles with the same credentials, the inability to access the Control Center UI was puzzling.

After conducting a thorough search of the VMware Knowledge Base, I came across an article that shed some light on my issue: vRealize Orchestrator 8.x cluster root password update fails in vRSLCM with error code LCMVACONFIG80003 or LCMVROVACONFIG100025. Although the article wasn’t a perfect match to my specific issue, it described a situation where changes to the “root” credentials on a vRealize Orchestrator appliance might not be synced to the vco-app container running within the appliance.

To resolve the issue, I executed a command to sync the password to the vco-app container, as documented in the article. The command is as follows:

“`

vco-app sync-password –password

“`

Where `` is the new password that you want to use for the “root” credentials.

After executing the command from one of the three vRealize Automation cluster nodes, the CLI logged that three vco-app containers had been destroyed. Within a few minutes, the containers were recreated, and the Control Center UI was again available. I then attempted to authenticate to the vRealize Orchestrator Control Center using the “root” credentials for the specific appliance from which I executed the command, and I was successful!

The exact cause of the issue is still unknown, but executing the above command corrected my issue and allowed me to access the Control Center UI using the current “root” credentials. As a precautionary measure, I plan to keep this command handy after the next round of password updates just in case the issue pops up again.

In summary, if you encounter authentication issues with vRealize Orchestrator and the vco-app container, try executing the `vco-app sync-password` command to sync the password to the vco-app container. This may resolve any issues related to password synchronization and allow you to access the Control Center UI using the current “root” credentials.

As a cloud architect, I’ve had the opportunity to work with a variety of technologies and solutions, but one of the most fascinating journeys has been my transition from infrastructure administration to cloud architecture. In this blog post, I’ll share my experiences and lessons learned from this journey, specifically focusing on a recent case study that highlights the importance of understanding vSAN stretched cluster design considerations.

Recently, I was working on a project where we had to design a highly available and scalable virtualized infrastructure for a client. We decided to use vSAN as our storage solution, and after researching and testing different configurations, we settled on a stretched cluster design. However, during the implementation phase, we encountered an issue that made us question the limitations of this design.

The issue arose when one of the hosts in the cluster became unresponsive and disconnected from the vCenter server. We tried to add a new witness host to replace the failed host, but found that we were unable to do so due to a limitation in vSAN’s design. Specifically, vSAN requires all hosts to be connected to the vCenter server before initiating reconfiguration operations, such as adding or removing witness hosts.

This limitation is intended to ensure that vSAN collects enough information from all hosts before initiating any changes, which helps prevent data corruption and ensures a smooth upgrade process. However, in our case, this limitation became a problem because we were unable to replace the failed host with a new witness host until the unresponsive host was brought back online.

At first, we thought this was a major issue that could potentially cause downtime and affect the availability of our infrastructure. However, after further research and testing, we discovered that vSAN can still rebuild data on other hosts even if one host is not responding. This means that we can still maintain the high availability and scalability of our infrastructure, even in the event of a host failure.

While this was a relief, it also raised some questions about why anyone would want to change witness hosts exactly when a host is not responding. After all, if a host is not available, vSAN will rebuild data on other hosts anyway, so why bother changing the witness host at that time? The answer lies in the fact that sometimes, maintenance and upgrades are unavoidable, and having the ability to change witness hosts during these times can be beneficial.

For example, if a host is scheduled for an upgrade or maintenance, it would be wise to change the witness host before the maintenance window begins. This ensures that the cluster remains highly available and scalable even during the maintenance period. Additionally, having the ability to change witness hosts as needed can help improve the overall reliability and availability of the infrastructure.

So, what’s the takeaway from this case study? The most important lesson I learned is the importance of understanding vSAN stretched cluster design considerations before implementing such a solution. While vSAN offers many benefits, such as high availability and scalability, it also has limitations that must be considered when designing and implementing a highly available infrastructure.

In conclusion, my journey from infrastructure administration to cloud architecture has been a rewarding one, filled with opportunities to learn and grow. The case study of our experience with vSAN stretched cluster design considerations highlights the importance of understanding the limitations and capabilities of storage solutions like vSAN. By doing so, we can design and implement highly available and scalable infrastructures that meet our clients’ needs and provide a solid foundation for their businesses.
