How to Check Virtual SAN Health 

If you want to make the right choice for your business, then you should consider choosing your personal virtual storage network. You put the entire burden of duty on yourself by choosing this. Now, only you will choose the level of service you offer to your clients. 

You are in charge of your vSAN. You will be in charge of maintaining a frequent eye on the storage area network’s performance and swiftly resolving issues as they arise. 

What do you need to know about virtual SAN?  

As the name suggests, this is a virtual representation of the storage network. You start using several simultaneously connected virtual machines instead of using a physical network of storage machines. 

You can set rules on how you would like the machines to allocate and also store all the data. The difference between a physical SAN and a virtual SAN is that you can monitor and resolve any issues that occur without disrupting the entire storage. Plus, you don’t have to turn off storage to troubleshoot.  

What should you be monitoring?  

Although a virtual SAN has many benefits, the administrator needs to take care of the health of key components regularly. This means that the hardware and software must run like clockwork, as well as all your settings.  

In addition, the administrator also needs to take care of the following:  

  1. Health. Health checks include checks for compatibility, service operation, network stability, storage health, data encryption, and so on;  
  2. Performance. The administrator should monitor throughput, latency, speed, and so on. It all depends on how the hardware and software work. The better the hardware, the more productive the software will run;  
  3. Devices. Although this storage is virtual, it does require some basic hardware to run. It is required to create shared storage pools. As a result, close attention must also be paid to all equipment components. 


The health of the virtual SAN is one of the most crucial aspects that an administrator has to monitor. It may be examined by utilizing the health service. Checks may be used to discover both minor and major issues that may have an impact on performance as well as to monitor the status of the cluster components. 

You could discover a diverse range of issues throughout the inspections. Some of these could be serious enough to result in myriads of minor issues. The administrator needs to understand how to fix the identified problems, because fixing one serious problem can immediately get rid of a dozen nested issues.

In addition, there may be other problems that are not related to each other. Thus, the specialist must understand how the system works. The knowledge base, which includes thorough information on each sort of issue, its causes, and solutions, is always available to the administrator in case of confusion or inexperience. 

Numerous elements affect the system’s overall health. As a result, these tests are separated into categories, each of which includes a different health check. 

By performing checks, you will be able to obtain the following information:  

  • Equipment compatibility. This enables you to keep track of how each cluster component is doing and confirm that the appropriate drivers, software, and hardware are being used; 
  • Efficiency;  
  • Network status; 
  • Physical disk failures; 
  • Encryption and information safety;  
  • Proper work of the cluster;  
  • Use of capacity; 
  • Build recommendations;  
  • Target service to track the status of execution and network configuration; 
  • Encryption of data, both at rest and in transit;  
  • The file service’s performance; 
  • Hosts’ current state and their settings. 

Performing health checkups 

The administrator must first visit the virtual SAN cluster. You should click the “Monitor” tab, which is located on the top line following the “Summary” tab. You should choose “Skyline Health” from the drop-down menu under the “vSAN” section on the left to access all the various categories for health tests. You have the option of checking the health in every way or choosing only the areas you need to keep an eye on right now. 

Yellow and red indicators will emerge as soon as the scan begins if there are any issues or faults. When a symbol is yellow, it means there are warnings, whereas red icons mean there have been some failures. 

If the check takes a long time, then at the top right, you can click on “Silence Alert” so that you are not distracted by notifications. After the check is over, you can view all the complaints about the operation of your network.  

Next to the “Overview” section, you will find the “Info” section, where you can open the knowledge base and find an article that describes the issues you are having. There you will also find information on how to fix any error.  

You can click the “Retest” option to see the most recent results if necessary. 

How to look up previous health checkups

Checks’ whole history is kept. You can look into check histories for certain periods if you need to look into recurring problems. You may only look at the history of cluster health checks, though.

You don’t need to do anything because this function is automatically activated. You can disable this functionality if you don’t require it. To accomplish this, locate the “Configure” tab behind the “Monitor” tab. Choose “vSAN” and “Services” next. You may click “Disable” next to “Historical Health Service.” Remember that if you disable it, all previous data will be lost. 

The storage period for all data is 30 days. You can choose periods, but the beginning of the chosen period cannot be set to begin earlier than thirty days from the present day. 

You can see the summary status for each check that was carried out for the chosen period by looking at the check history. You will have the same green, yellow, and red symbols indicated as with a typical check. Green means that everything is in order. Yellow is a warning and red is a failure. All information about checks will be displayed in the form of a table.  


By choosing a virtual SAN, you assume responsibility for its correct operation. The administrator must promptly monitor performance, run routine device checks, and execute cluster health checks to manage to address issues that might negatively impact your job. The sooner potential issues are identified, the sooner they may be fixed.
