VMware-View Replica and Snapshot

I have a VM(windows7), I have created a snapshot of it,, Then on Vmware View I created a new Pool , going through Pool creation wizard ,I selected the location  of the VM and the Snapshot, at the end of the wizard, I ended up with a Replica in Vcenter.
I would like to know what is the Replica made of. I checked the size of the VM disk, the snapshot, and the Replica, they all have different sizes... I believe the Linked clone (new VMs that get created automatically later), are based on the Existing snapshot I selected on the  Pool creation wizard, in addition to the Replica.

Example:

VM (Base)
Snapshot
Replica

First VM = will be created from Replica + Snapshot
Second VM = how is it going to be created ??

Any VM-view EE to put up a clear picture on how this mechanism work ?


Thank you

We've been through this before....

see here

vmware view snapshot and replica

The Replica is the object which the VDI VMs are made from.

So all Linked Clones are created from Replica and Snapshot, the 1st the 2nd, and the last....

Here is a picture, to demonstrate

In no-persistent VM (when user logs off, the linked clone VM is deleted) it will make sense, because all linked clone VMs may  write to the same Snapshot. and  the Replica will be the Base disk (that the linked close use as OS)


In Persistent VM(where user gets the same VM each time), will the linked clone VM be writing to the same snapshot as other VMs ?  or will it have separate snapshots from other Linked clones but the same Replica as other linked clone VMs ?
Just remember for every linked clone there is a separate snapshot for EVERY VDI CLONE, that is the LINKED CLONE part to the Master Replica.

As for Replica, that could be the same parent which is being read from e.g. Parent, but other replicas could be generated depending upon numbers.

But each individual VM is writing to it's own snapshot. not shared.
