The diagram above shows a simple VCL configuration with 1 management node and
2 VMware ESXi hosts. Network storage is not used.
The local disks on the VM hosts are used to store all of the files used by
running VMs including the VM's working directory and the master vmdk image.

This example is identical to the one above except that the repository located
on the management node's local disk is not exported via NFS. Because of this,
images must be transferred using SCP instead of vmkfstools. This is less
desirable than mounting the repository directly on the VM hosts because images
cannot be copied and converted in a single step. Images are stored in the
repository in the 2GB sparse format. This allows the images to be copied via
SCP while only transferring the data stored in the image, not the entire size
of the hard drive stored in the image. VMware ESXi cannot run VMs using vmdk
images stored in the 2GB sparse format. Images are converted to the vmfs thin
format so that they can be loaded on VMware ESXi. This adds extra time to the
load process if an image does not exist in the VM's local datastore (Virtual
Disk Path) and must be copied from the repository. It also requires additional
space in the VM host's local datastore (Virtual Disk Pa
th) becuase 2 copies of the image exist while it is being converted.
Note that the VM host profile Repository Path parameter is set to the path on
the management node's hard drive. The code first checks if the path exists on
the VM host. If not, it assumes the repository is not mounted directly on the
VM host and the Repository Path value refers to a location on the management
node.

A datastore to be used as the VM Working Directory Path named "vmpath" is also
mounted on each VM host. However, the location to which each VM host points
should be different. In the example above, vmhost-a-01 points to th the
/vmpath01 directory on the network storage and vmhost-a-02 points to the
/vmpath02 directory. These locations may be different network storage
filesystems or may be different directories on the same network filesystem.
Even though the mounts on the VM hosts point to different locations, the
datastore names configured under ESXi are identical. This allows you to use
the same VCL VM host profile for all of the VM hosts.
