    <description>&lt;P&gt;&lt;SPAN&gt;For the 1st Question :&lt;BR /&gt;As per the docs it says you can for 4 mgmt domains or 4 workload domain but we can't federate WLD with mgmt.&amp;nbsp;domains. The&amp;nbsp;main reason for this is to keep management components separate from WLD components.&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN&gt;2nd Question :&amp;nbsp; i think it design choice I would assume but within those 2 regions you could have 2 AZ's.&amp;nbsp; So, would be 4 management domains.&lt;/SPAN&gt;&lt;/P&gt;</description>

      <description>&lt;P&gt;The following documentation says:-&lt;/P&gt;&lt;P&gt;&lt;A href="https://docs.vmware.com/en/VMware-Cloud-Foundation/4.4/vcf-admin/GUID-E515E638-5212-49D2-979A-99A8496876AD.html" target="_blank"&gt;https://docs.vmware.com/en/VMware-Cloud-Foundation/4.4/vcf-admin/GUID-E515E638-5212-49D2-979A-99A8496876AD.html&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&lt;EM&gt;You can federate the management domain NSX Data Center or a VI workload domain NSX Data Center. &lt;STRONG&gt;Since &lt;SPAN&gt;VMware Cloud Foundation&lt;/SPAN&gt; (VCF) supports a maximum of four federated NSX Managers,&lt;/STRONG&gt; you can federate four management domains or four VI workload domains. More than four VI workload domains can be federated if they share an NSX Manager&lt;/EM&gt;&lt;/P&gt;&lt;P&gt;We plan for 3 separate instances of vCF with both Management and Workload domains federated. Is this supported?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The following documentation says:-&lt;/P&gt;&lt;P&gt;&lt;A href="https://docs.vmware.com/en/VMware-Cloud-Foundation/4.3/vcf-management-domain-design/GUID-11177D00-C8BE-4CEC-B997-659CC03B6D12.html" target="_blank"&gt;https://docs.vmware.com/en/VMware-Cloud-Foundation/4.3/vcf-management-domain-design/GUID-11177D00-C8BE-4CEC-B997-659CC03B6D12.html&lt;/A&gt;&lt;/P&gt;&lt;P&gt;Regions are geographically separate, with a maximum round-trip latency between them of 150 ms. &lt;STRONG&gt;If you plan to use NSX Federation between regions, VMware Cloud Foundation supports a maximum of &lt;U&gt;two regions&lt;/U&gt;&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;We plan for 3 regions with NSX-T federation. NSX-T happily supports 3 sites / regions so why does vCF limit this option or is this even correct with regard to federating NSX-T instances in a vcf management or workload domain.&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks for replying. I appreciate your reply. I'm reading this differently however.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;EM&gt;&lt;STRONG&gt;Since &lt;SPAN&gt;VMware Cloud Foundation&lt;/SPAN&gt; (VCF) supports a maximum of four federated NSX Managers,&lt;/STRONG&gt; you can federate four management domains &lt;U&gt;&lt;STRONG&gt;or&lt;/STRONG&gt;&lt;/U&gt; four VI workload domains.&lt;/EM&gt;&lt;/P&gt;&lt;P&gt;I have highlighted the &lt;U&gt;&lt;STRONG&gt;or&lt;/STRONG&gt;&lt;/U&gt; in the above statement myself. Its important as it suggest this is an either or statement.&lt;/P&gt;&lt;P&gt;It suggest to me that any one instance of vCF supports a &lt;STRONG&gt;maximum&lt;/STRONG&gt; of &lt;U&gt;&lt;STRONG&gt;4&lt;/STRONG&gt;&lt;/U&gt; federated NSX Managers. NSX-T Managers would not be federated across Management and Workload as this would not make any sense as these are discrete vSphere vCenters and NSX-T Managers.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Therefore for example where I wish to federate NSX- Management across two other sites I will have three federated NSX-T Managers in that instance of vCF. Then when I wish to federate NSX-T Managers for the workload domains across 2 additional sites I will have an additional three federated NSX-T Managers for a TOTAL of 6 federated NSX-T Managers. The question I have is whether this is possible. The statement suggests not. This is difficult to understand as no such limitation exists in NSX-T.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The next issue...&lt;/P&gt;&lt;P&gt;Regions are geographically separate, with a maximum round-trip latency between them of 150 ms. &lt;STRONG&gt;If you plan to use NSX Federation between regions, VMware Cloud Foundation supports a maximum of &lt;U&gt;two regions&lt;/U&gt;&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;This is a terminology question I expect. I wish to use 3 vCF instances in three separate sites. Is this supported. when federating each site. Again NSX-T has no limitations but the documentation suggest vCF does!? Why.&lt;BR /&gt;&lt;/P&gt;</description>

      <description>&lt;P&gt;Worth checking with VMware (TAM or support call) about the two regions, I only see that mentioned in v4.3 docs so maybe it no longer applies?&lt;/P&gt;&lt;P&gt;We haven't done federation yet (but are due to shortly) but only have two regions and a single Management + VI WLD in each so are within the limits. Even if we had multiple VI WLDs we would generally just have them sharing an NSX Manager - it sounds like you have multiple VI WLDs within a deployment and each has a dedicated NSX Manager?&lt;/P&gt;</description>
