What are datastores in VMware?
Datastores in VMware vSphere are storage containers for files. They could be located on a local server hard drive or across the network on a SAN. Datastores hide the specifics of each storage device and provide a uniform model for storing virtual machine files.

How do I access vmfs datastore?
Accessing VMFS Datastore from Windows You can download Open Source VMFS Driver here: https://code.google.com/archive/p/vmfs/.

What happens when datastore runs out of space?
When a datastore runs out of space, thin-provisioned virtual disks can no longer dynamically grow to accommodate additional storage demand. When VMware ESX detects this condition, virtual machines in need of additional storage are instantly paused to prevent guest operating systems from failing.
How do I free up space on my datastore?
Remove ISO files from the datastore….To solve the problem permanently:
- Add disks to the server and expand the VMFS, or create a new datastore.
- Add a NFS datastore.
- Remove unnecessary VMs.
- Setup a working monitoring , setup alarms, do not overprovision datastores, or switch to eager-zeroed disks.
How do I check storage on ESXi?

- Read the data from the device where device is a value found in step 3:
What is the difference between datastore and database?
A data store is a repository for persistently storing and managing collections of data which include not just repositories like databases, but also simpler store types such as simple files, emails etc. A database is a series of bytes that is managed by a database management system (DBMS).
What is the difference between NFS and VMFS datastores?
Like we stated above, VMFS is a block level file system, while NFS is a file level file system. When creating a VMFS Datastore, the VMFS file system is created by the vSphere, while the NFS file system is on Storage side and is only mounted has a shared folder on the vSphere.

Where are VMFS files stored?
VMFS deposits files in a storage container called a datastore, a separate filesystem that runs on top of a volume. Datastores reside on a block-based device such as iSCSI. Virtual machine disks (VMDKs) are housed in the datastore.
