Eth card planning¶
This page describes how to plan network adapters based on different network solution combinations before creating a workload cluster. Please complete Cluster Deployment Plan and network card planning before cluster deployment.
Overlay scheme only¶
When the application Pod in the cluster only needs to use a single CNI and does not need to provide external access, only the component Calico/Cilium needs to be deployed, and the network card planning is also relatively simple. The specific network card planning is as follows:
| Deployment Environment | Infrastructure | Number of NICs | NIC Description | Purpose |
|---|---|---|---|---|
| PoC environment | Physical machine Virtual machine Public cloud | 1 physical network card/Bond network card | Access mode access, the network card where the default route is located 1 | Bearer K8s management traffic, Calico Pod traffic |
| Production environment | Physical machine Virtual machine Public cloud | 1 or 2 physical network cards/Bond network cards | NIC 1: Access mode access, the network card where the default route is located< br />NIC 2 2 (optional): Access mode access | NIC 1: carry K8s management traffic, Calico Pod traffic NIC 2: Hwameistor data replicas synchronize traffic across nodes |
Overlay + Underlay scheme¶
When the cluster deployment application needs to use a combination of multiple CNIs and Underlay CNI (Macvlan/SR-IOV) IP to provide external communication, the network component combination that can be used is Calico + SpiderPool + Multus + Macvlan/SR-IOV (the same cluster can Deploy Macvlan and SR-IOV CNI at the same time). The specific network card planning is as follows:
| Deployment Environment | Infrastructure | Number of NICs | NIC Description | Purpose |
|---|---|---|---|---|
| PoC environment | Physical machine Virtual machine | 1 physical network card / Bond network card | Access mode access, the network card where the default route is 1 | Carrying K8s management traffic, Calico Pod Traffic, Underlay CNI (Macvlan) Pod Traffic |
| Production environment | Physical machine Virtual machine | 2 physical NICs/Bond NICs | NIC 1: Access mode access, the network card where the default route is located NIC 2 1: Trunk mode access | NIC 1: carrying K8s management traffic, Calico Pod traffic NIC 2: carrying Underlay CNI (Macvlan/SR-IOV) Pod Traffic |
| Production environment | Physical machine Virtual machine | 3 physical network cards/Bond network cards | NIC 1: Access mode access, the network card where the default route is located NIC 2 2: Trunk mode access NIC 3 (optional): Access mode access | NIC 1: carrying K8s management traffic, Calico Pod traffic NIC 2: carrying Underlay CNI (Macvlan/SR-IOV) Pod traffic NIC 3: Hwameistor data copy cross-node synchronization traffic |
