Creating and Modifying
a VMFS Datastore
A datastore is a
manageable storage entity, usually used as a repository for virtual machine
files including log files, scripts, configuration files, virtual disks, and so
on.
VMFS is a proprietary file system VMware designed
for virtual machines. VMFS is well suited for storing a small number of large
data files like virtual disks. These files are mostly used by a single host.
VMFS differs from other filesystem formats like FAT16/FAT32 and so on in that
it can be accessed by multiple hosts connected to the same SAN LUN.
You can set up a VMFS datastore on any SCSI-based
storage device that the host can access. VMFS volume creation, extension, and
expansion requires first partitioning operations and the VMFS volume
operations.
