Infrastructure Automation validates various prerequisites for each site before beginning the actual deployment.

Different sites have different prerequisites that must be fulfilled before beginning the actual deployment. Infrastructure Automation validates all these prerequisites to ensures easy and fast deployment.

Host

  • All hosts in a domain are homogeneous.
  • Each host has a minimum of one solid-state disk (SSD) and three solid-state disk/hard disk drives for vSAN.
  • Each host requires two physical NICs connected to the same physical switch.

Physical Switch

  • Jumbo Frames enabled on the Physical Switch.
  • DHCP enabled on the NSX host overlay network.
  • Each ESXi server has a minimum of two physical NICs connected to the switch in trunk mode. Access to all the VLANs on the trunk port.

Domain

  • Each domain has a minimum of four hosts.
  • DNS name configured for all the appliances in all the domains.
  • ESXi servers are installed for each domain through the PXE server or ISO image.
  • A common web server to access the software images at the central site.
  • Central and regional sites have the internet connectivity.

Network

  • TCA/TCA-CP will require an unrestricted communication to connect.tec.vmware.com and hybridity-depot.vmware.com over port TCP 443 for license activation and updates.
  • Time synchronization through NTP for all VLANs.
  • Unique VLANs are created for following:
    Network MTU Description
    Management Network 1500 Used to connect the management components of the software like vCenter, ESXi, NSX Manager, VMware Telco Cloud Automation, and VMware Telco Cloud Automation Control Panel.
    vMotion Network 9000 Used for the live migration of the virtual machines. It is a L2 routable network and used only for the vMotion traffic within a data center.
    vSAN 9000 Used for the vSAN traffic. It is a L2 routable network and used only for the vMotion traffic within a data center.
    NSX Host Overlay Network 9000 Used for the NSX Edge overlay traffic. Requires a routable with Host overlay VLAN in the same site. This network requires a DHCP server to provide IPs to the NSX host overlay vmk interfaces. The DHCP pool should equal the number of ESXi hosts on this network.
    NSX Edge Overlay Network 9000 Used for the overlay traffic between the hosts.
    Uplink 1 9000 Used for the uplink traffic. Uplink 1 is in the same subnet as the Top of Rack (TOR) switch uplink address.
    Uplink 2 9000 A redundant path for the uplink traffic. Uplink 2 is in the same subnet as the Top of Rack switch uplink address.
  • Each ESXi server has a minimum of two physical NICs connected to the switch in trunk mode. Access to all the VLANs on the trunk port.
  • Name resolution through DNS for all appliances in all the domains.
  • DNS records for all appliances with forward and reverse resolution. DNS records which use prefix are as follows:
    DNS Host Name Static Prefix
    ESXi Hosts (an entry for each ESXi host) No static prefix. For example, esxi-01-mydomain.
    Virtual Center No static prefix. For example, vcenter-mydomain.
    vRealize Operations Manager Optional. No static prefix. For example, vro-mydomain.
    NSX Manager No static prefix. For example, nsxmgr-mydomain.
    nsx001 Static prefix. For example, nsx-001-mydomain.
    nsx002 Static prefix. For example, nsx-002-mydomain.
    nsx003 Static prefix. For example, nsx-003-mydomain.
    nsx-edge001 Static prefix. For example, nsx-edge001-mydomain.
    nsx-edge002 Static prefix. For example, nsx-edge002-mydomain.
    Telco Cloud Automation No static prefix. For example, tca-mydomain.
    Telco Cloud Automation Control Panel No static prefix. For example, tca-cp-mydomain.
    SDDC Manager No static prefix. For example, sddcmgr-mydomain.
    Cloud Builder No static prefix. For example, cloudbuilder-mydomain.
    Kubernetes Boot Strapper No static prefix. For example, tkg-bs-mydomain.
