During the bring-up process, you are required to provide company domain, management network, and vSAN, VXLAN, vMotion, data center network settings. You must collect this information before starting the bring-up process.

Table 1. Description of Networks

Title

Description

Management network

Network that provides public access to Cloud Foundation components in the management domain.

vMotion network

Network for vMotion across hosts.

vSAN network

Network for vSAN and vSphere HA inter-host communication.

VXLAN network

Network for internal communication between Cloud Foundation management components.

Data center network

Network used to access customer VMs from your corporate network.

VMware recommends that you print this table and fill in the required values. Keep this printout handy during the bring-up process.

Table 2. Information Required for Bring-Up

Category

Information Required

Example

Rack Details

Physical Rack name

Rack names allow you to map the IDs SDDC Manager assigns to a host or a switch with the physical rack containing the host or switch. You need to specify the rack name during bring-up and while adding a rack. A best practice is to specify the name affixed to the physical rack along with location details such as the datacenter the rack is located in.

ABC

Company name

MyCompany

Company Department

My department

Root DNS Domain

Must be the same as the domain defined in DNS naming system.

mycompany.local

Cloud Foundation Sub-domain

Each Cloud Foundation system must have a unique sub-domain.

vcf01-domain.mycompany.local

SSO Domain

mycompany.local

VMware Cloud Foundation License Key

11111-11111-11111-11111-11111

Management Network

vMotion Network

vSAN Network

For each network, you must provide values for VLAN ID, subnet, subnet mask, gateway, and excluded addresses (optional). You can either use system generated values for these, or specify your own values.

VLAN ID

Supported VLAN range is 24-3967.

24

Subnet

10.0.24.0

Subnet Mask

255.255.252.0

Gateway

10.0.24.1

Primary DNS (management network only)

10.172.40.1

Secondary DNS (management network only)

10.172.40.2

NTP (management network only)

10.172.40.100

Exclude IP Address Ranges (Optional)

If you have already used a set of IP addresses in your deta center or do not want to use certain IP addresses, you can exclude them from Cloud Foundation provisioning.

VXLAN Network

VLAN ID

Supported VLAN range is 24-3967.

102

Subnet

10.0.102.0

Subnet Mask

If you intend to specify a large IP subnet mask (for example, /22) for VXLAN during the bring-up phase of installation and subsequently to be used for new VI/VDI workload domain configurations, the following recommendations apply.

  • Cloud Foundation uses the NSX Unicast Replication mode by default, which may result in ESXi host overhead when a high number of ESXi hosts belong to a single subnet.

  • VXLAN ESXi host overhead also depends on the amount of multi-destination broadcast, unknown unicast, and multicast (BUM) traffic.

  • To avoid high ESXi host overhead, it is recommended that you use a dedicated IP subnet/VLAN for VXLAN for each VI/VDI workload domain.

For more information about the NSX Unicast Replication mode, see Add a Transport Zone in the NSX product documentation.

255.255.252.128

Gateway

10.0.102.1

Exclude IP Address Ranges (Optional)

If you have already used a set of IP addresses in your deta center or do not want to use certain IP addresses, you can exclude them from Cloud Foundation provisioning.

Data Center Network

VLAN ID

Supported VLAN range is 24-3967.

225

Subnet

10.0.225.0

Subnet Mask

255.255.252.224

Gateway

10.0.225.1

Exclude IP Address Ranges (Optional)

If you have already used a set of IP addresses in your deta center or do not want to use certain IP addresses, you can exclude them from Cloud Foundation provisioning.

Data Center Uplink

Uplink Type

Choose L2 or L3. If you choose L3, you will also need the upstream router (next hop) information.

L2

Uplink LAG

Enable or disable uplink LAG (Link Aggregation Group). LAG aggregates multiple links into a single bundle. You can enable this option if the speeds on the ports in your environment match. For example, if you have 4 uplink ports at 10G, you can get up to 40G with LAG enabled.

Yes

Uplink Ports

For 10 Gb ports, specify 43 to 46.

For 40 Gb ports, specify 51 to 54.

43, 44

Uplink speed

Specify 1 G, 10 G, or 40 G

10 G
