Dell VxRail Network Planning Guide
Decide on an IP address scheme
For VxRail 8.0.210 and later, you can deploy VxRail with IPv6 and Dual Stack, in addition to IPv4.
The following table provides the supported IP addressing option for VxRail versions:
| VxRail versions | Supported IP addressing |
|---|---|
| VxRail versions earlier than 8.0.210 | Single-stack IPv4 |
| VxRail 8.0.210 and later | Single-stack IPv4 |
| Single-stack IPv6 | |
| Dual-stack IPv4/IPv6 |
The option to use with VxRail impacts the data center preparations and how the VxRail cluster is deployed.
If you deploy VxRail using single-stack IPv4:
- Reserve IPv4 addresses on all VxRail networks.
- Verify that connectivity to data center services and external services supports IPv4.
If you deploy VxRail using single-stack IPv6 :
- Reserve IPv6 addresses on all VxRail networks.
- Verify that connectivity to data center services and external services supports IPv6.
If you deploy VxRail using dual-stack IPv4/IPv6:
- Reserve IPv4 and IPv6 addresses for the VxRail external management network.
- Verify that connectivity to required data center services (DNS, NTP) supports IPv4 and IPv6.
- Verify that connectivity to data center services (DNS, NTP) supports IPv4 or IPv6.
- External connectivity can be either IPv4 or IPv6.
