How to Configure vSAN Step by Step

In this series of vSAN we already know now what is vSAN and how it works. vSAN provides the storage policies which is then assigned to each vm or vmdk object. vSAN storage policies we have discussed in the last post. If you haven’t visited yet links are available in the end of this post for all the vSAN related articles. Make sure you have VMware vSAN compatible hardware servers and the disks required one flash and one hdd is minimum per ESXi Host.

Before configuring vSAN we required vSAN VMk to be configured which we have seen in the last post on how to configure vSAN VMkernel step by step. vSAN VMkernel requires on all the hosts which are participating in the vSAN. So if you have missed any host make sure to create a vSAN VMkernel to avoid the configuration issues later.

In this post we will see on the first time how to configure vSAN on the cluster. Where we already having an cluster running in the vCenter Server. So we will be configuring the vSAN on the cluster.

Step 1:
Login to vSphere Web Client.
Choose the cluster on which you want to configure vSAN.
Go to Configure Tab > Click General under vSAN.
Click on Configure button.


Step 2:
vSAN Configuration wizard will open.
Choose the services which you want to configure with vSAN.
We will see on the services part later in this series. Right now we will be focusing only on configuring vSAN.
Click Next.


Step 3:
Here you will see the Network validation results which will show the vSAN VMkernel status.
If all are configured then you can go ahead and click Next.
If any host is missing then create the vSAN VMkernel first.
Click Next.


Step 4:
This is the important part of the vSAN Configuration. Here you will be selecting the disks which you want to use with vSAN.
Make sure you have one SSD and one HDD disks in each of the ESXi Hosts.
vSAN will automatically claim the disks for the vSAN Datastore. If you want to manually configure then choose the disk which you want to use as cache or capacity.
Make sure the disk configuration is properly configured in all the hosts.
Click Next.


Step 5:
Review all the configuration you have done.
Here you will get the overview about the storage capacity of the datastore such as vSAN Datastore capacity and total cache.
Click Finish to start the configuration process.


Once you click Finish you will see multiple operations going on in the recent tasks for vSAN Creation.


It will take few minutes to complete the configuration based on the environment.
Once it is configured you will see that vSAN is turned On.
You can see features and various information about the vSAN here.



If you want to see the vSAN Datastore then go to the datastore view.
You will find vsanDatastore is created.
Click on the datastore to view its information.



That’s it. Using this way you can easily configure the vSAN in your environment. Before configuring in production make sure you have full filled all the requirements of the vSAN to avoid the future issues.
