VMware has recently announced the vSphere 7 with the ESXi 7 & other solutions. So if you have already installed ESXi 7 in your environment than in that case you may observe this change as sometimes local datastore is not visible in ESXi. Don’t worry this is related to ESXi architecture changes so nothing to worry about. We will help you to learn in which case you will see local datastore in ESXi 7 & in which case you won’t be able to see local datastore.
So when we were testing ESXi 7 in our LAB we have found that we unable to see the local datastore in ESXi in some cases but in some cases we were able to see the local datastore. In this post we will help you with 2 scenarios in which you will see the local datastore & how you can actually view more about it.
What is Local datastore:
Local datastore is nothing but local disk of your physical server where your ESXi gets installed, ESXi system partitions gets created & you will get some free space local datastore to use it for storage of virtual machine files, ISO etc. But it is not recommended to use the the local datastore for your Production Virtual Machines. This local datastore gets created automatically you don’t have to create it manually.
Scenario 1: Here we have installed ESXi 7 & we can see that we don’t have any local datastore visible.
In this scenario 1 we have installed ESXi on the 60 GB disk & tested it further for the same.
We can see in Storage Devices that our local disk is present where ESXi is installed. Here we can view more details about it.
Now If we go to Partition Details , Here you can see all the partitions on the ESXi host & there is no VMFS partition available.
Hence there is no VMFS partition on the ESXi host you won’t be able to see the local datastore & use it.
Scenario 2: Here we have installed ESXi 7 & we can see that we have local datastore visible:
In Scenario 2 we have installed ESXi 7 on the 142 GB disk & tested it further for the same.
ESXi is showing the local datastore size of 13.75 GB.
We can see in Storage Devices that our local disk is present where ESXi is installed & we can view more details about it.
Now If we go to Partition Details , Here you can see all the partitions on the ESXi host & there is one VMFS partition of 14 GB. So that is our local datastore which is visible to us. Remaining space is used by the ESXi system storage management.
As you all are aware now that how we can see the local datastore of the ESXi & where we can see it’s partition details. Our goal for this post is to only clear your doubts so that in future whenever you install fresh ESXi on the server you are already aware about this fact & you don’t worry about it.
ESXi has it’s own system storage partitions which are used for different purposes & they are assigned specific sizes to each partition. So in case of ESXi 7 if any of the local disk size is below 128 GB you won’t get the local datastore but if the size is more than 128 GB than you can see that you have local datastore available after the system partition size is utilized. This is due to the system storage partition change in the ESXi architecture.
In this post we have used the VMware Blogs ESXi 7 System storage changes blog post as a reference.
Below is the official link of the post from VMware where you can read in detail about it:
