    <title>topic Does vSphere Replication pre-allocate disk space for replicated VMs? in vSphere Replication Discussions</title>

    <description>&lt;P&gt;Does vSphere Replication pre-allocate disk space for replicated VMs?&lt;BR /&gt;&lt;BR /&gt;Here's my scenario.&amp;nbsp; I'm setting up replication for a VM that is 6TB.&amp;nbsp; At the recovery site I see datastore A has 8TB free,&amp;nbsp; I choose that datastore. VSR is happy.&lt;BR /&gt;&lt;BR /&gt;Someone else comes along a few minutes later and sets up replication for another VM that is 4TB.&amp;nbsp; They see datastore A has 8TB and they choose that. VSR is also happy. VSR doesn't seem to say "Hey, I have this 6TB replicating so you can't stick your 4TB VM there" when you setup replication for the second VM.&amp;nbsp;&lt;BR /&gt;&lt;BR /&gt;Now, throw on top of this DRS.&amp;nbsp; Before the 6TB VM finishes the initial sync, DRS comes along and throws a few TB of other VMs on datastore A so now, the 6TB replication fails.&lt;BR /&gt;&lt;BR /&gt;Am I doing something wrong?&amp;nbsp; Does VSR not communicate with DRS? If you're replicating a 6TB VM, shouldn't VSR set aside that space so other VMs don't end up on that datastore before replication finishes?&lt;/P&gt;</description>

      <description>&lt;P&gt;Vsphere replication should communicate with storage DRS.&lt;/P&gt;&lt;P&gt;&lt;A href="https://docs.vmware.com/en/vSphere-Replication/8.6/com.vmware.vsphere.replication-admin.doc/GUID-B2004022-83C2-4D82-B9E1-24616CFBDD99.html#:~:text=vSphere%20Replication%20can%20operate%20with,without%20affecting%20the%20replication%20process" target="_blank"&gt;https://docs.vmware.com/en/vSphere-Replication/8.6/com.vmware.vsphere.replication-admin.doc/GUID-B2004022-83C2-4D82-B9E1-24616CFBDD99.html#:~:text=vSphere%20Replication%20can%20operate%20with,without%20affecting%20the%20replication%20process&lt;/A&gt;.&lt;/P&gt;&lt;P&gt;If possible you can also choose to have separate datastores for specifically using VSR.&lt;/P&gt;</description>
