Diagnostics and Troubleshooting Reference Manual – Virtual SAN
A virtual machine deployed on a Virtual SAN datastore is comprised of a set of
objects. These are the VM Home Namespace, the VMDK, VM Swap when the VM is
powered on and Snapshot Delta VMDKs when snapshots are taken on the VM. New
to version 6.0 is the virtual machine snapshot memory, which is now instantiated as
its own object when a virtual machine snapshot is taken and memory is also
selected:
Each of the objects is comprised of a set of components. For example, if
NumberOfFailuresToTolerate=1 is set in the VM Storage Policy, then some of the
objects would be mirrored/replicated, with each replica (and witness) being a
component.
If NumberOfDiskStripesPerObject is greater than 1 in the VM Storage Policy, then
each stripe is also said to be a component of the object.
