What are extents in VMware?

What are extents in VMware?

VMFS filesystems allow one to have the filesystem spread across more than one storage volume (such as a SAN LUN). The additional volumes beyond the first such volume are called extents. VMware does not provide a mechanism to remove an extent from a VMFS filesystem once it has been added.

What is multi extent datastore?

Extents allow disk presented to a vSphere system to be added to VMFS datastore to extend the file system, this aggregates multiple disks together and can be useful in a number of scenarios. Using extents allows you to create datastores up to the maximum supported by vSphere for pre-VMFS-5 datastores.
