      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;i'm really interested to know that how many IDs exists for a VM???&lt;/P&gt;&lt;P&gt;i did some search and i found that there are 15 unique and specific IDs associated to each VM, is it correct??&lt;/P&gt;&lt;P&gt;if yes, what make them unique and guarantee that two VM on to different ESXi Host&amp;nbsp; won't have the same IDs??&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi,&lt;BR /&gt;to identify objects/entities in vSphere environment there are two properties which ensures its uniqueness:&lt;BR /&gt;- &lt;STRONG&gt;instanceUUID&lt;/STRONG&gt; (128-bit integer) &lt;EM&gt;[replacement for SMBIOS UUID]&lt;/EM&gt;&lt;BR /&gt;- &lt;STRONG&gt;MoRef ID&lt;/STRONG&gt; (vm-214; cluster-3 ...)&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;these are not only assigned to VMs but also to other VI "objects" like hosts, datacenters, clusters, datastores ...etc.&lt;BR /&gt;by combining instanceUUID with MoRef ID you can uniquely identify objects across multiple vCenter server instances.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;For more detailed and precise info look at these great posts:&lt;BR /&gt;&lt;A href="http://www.virtuallyghetto.com/2011/11/vsphere-moref-managed-object-reference.html" title="http://www.virtuallyghetto.com/2011/11/vsphere-moref-managed-object-reference.html"&gt;http://www.virtuallyghetto.com/2011/11/vsphere-moref-managed-object-reference.html&lt;/A&gt;&lt;BR /&gt;&lt;A href="http://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-1-overview.html" title="http://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-1-overview.html"&gt;Uniquely Identifying Virtual Machines in vSphere and vCloud Part 1: Overview | VMware vSphere Blog - VMware Blogs&lt;/A&gt;&lt;BR /&gt;&lt;A href="http://blogs.vmware.com/vsphere/tag/instanceuuid" title="http://blogs.vmware.com/vsphere/tag/instanceuuid"&gt;instanceUuid | VMware vSphere Blog - VMware Blogs&lt;/A&gt;&lt;BR /&gt;&lt;A href="http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&amp;amp;cmd=displayKC&amp;amp;externalId=1017126" title="http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&amp;amp;cmd=displayKC&amp;amp;externalId=1017126"&gt;VMware KB: Looking up Managed Object Reference (MoRef) in vCenter Server &lt;/A&gt;&lt;BR /&gt;&lt;A href="http://pubs.vmware.com/vsphere-50/topic/com.vmware.vddk.pg.doc_50/vddkBkupVadp.9.2.html" title="http://pubs.vmware.com/vsphere-50/topic/com.vmware.vddk.pg.doc_50/vddkBkupVadp.9.2.html"&gt;Design and Implementation Overview&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-size: 8pt;"&gt;_________________________________________________________________________________________&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN style="font-size: 8pt;"&gt;If you found this or any other answer helpful, please consider to award points.

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Thank you vNex that was very helpful, i'm working with couple of ESXi single hosts in my Datacenter and for now i don't have any vCenter infrastructure.&lt;/P&gt;&lt;P&gt;so without considering &lt;SPAN style="color: #666666; font-family: proxima-nova, Arial, sans-serif; font-size: 14px;"&gt; datacenters, clusters, datastores&lt;/SPAN&gt; i just need to find unique IDs assigned to a VM on a ESXi host. Also i would really appreciate if you can tell me that how many are they??&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;If you do not have vCenter server. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;One of the ways to know VM managed object reference (MO Ref)@VMs,datastores is to explore the managed object browser (mob) as follows:&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN&gt;Open browser &amp;gt;&amp;gt;open this URL&amp;gt;&amp;gt;"&lt;/SPAN&gt;&lt;A class="jive-link-external-small" href="https://"&gt;https://&lt;/A&gt;&lt;SPAN&gt;&amp;lt;Your ESXi host IP&amp;gt;/mob"&amp;nbsp; &amp;gt;&amp;gt;This will prompt you to enter ESXi credentials &amp;gt;&amp;gt;Then just explore.&lt;/SPAN&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
