- The IP address scheme must be a public IP address range.
- The IP address must be fixed (no DHCP).
- The IP addresses cannot be in use.
- The IP address range must all be in the same subnet.
- You can manually assign the IP addresses to the ESXi hosts.
- You can have the IP addresses auto-assigned during VxRail initial build.
- Decide if you want to reserve additional IP addresses for VxRail management to assign to VxRail nodes in the future for expansion purposes in a single rack. When a new node is added to an existing VxRail cluster, it assigns an IP address from the unused reserve pool, or prompts you to enter an IP address manually if none are in reserve and unused.
- Decide whether you are going to use the VMware vCenter Server instance that is deployed in the VxRail cluster or use an external VMware vCenter Server already operational in your data center.
- If you use the VMware vCenter Server instance that is supplied by VxRail, you must reserve an IP address for VMware vCenter Server.
- Decide if you are going to use VMware vSphere Log Insight that can be deployed in the VxRail cluster.
- For VxRail version 7.0 and earlier, if you use the VMware vCenter Server instance that is deployed in the VxRail cluster, you have the option to deploy VMware vSphere Log Insight on the cluster. You can also choose to connect to an existing syslog server in your data center, or no logging at all. If you choose to deploy VMware vSphere Log Insight in the VxRail cluster, you must reserve one IP address.
- VMware vRealize Log Insight is not an option for deployment during the initial VxRail configuration process starting with version 7.0.010.
- If you use an external VMware vCenter Server already operational in your data center for VxRail, VMware vSphere Log Insight cannot be deployed.
Use the following table to determine the number of public IP addresses required for external connectivity:
|VxRail Node||One per VxRail Node|
|VMware vCenter Server|| |
|VMware vSphere Log Insight|| |
Request your networking team to reserve a subnet range that has sufficient open IP addresses to cover VxRail initial build and any planned future expansion.
|Network configuration table||Action|
|Row 8||Enter the subnet mask for the VxRail External Management network.|
|Row 9||Enter the default gateway for the VxRail External Management network.|
