| OpenShift Data Foundation Storage | As per platform | It is used to manage shared storage for the Cloud Native SBC. |
Supported NICs and Drivers
In private virtual infrastructures, Cloud Native SBC supports the following interface input-output modes, ethernet controller, drivers, and traffic type based on input-output modes.
Supported Interface Input-Output Modes for Private Virtual Infrastructures
- Para-virtualized
- SR-IOV
Supported Ethernet Controller, Driver, and Traffic Type based on Input-Output Modes
The following table lists supported Ethernet Controllers (chipset families) and their supported driver that ORACLE supports for the Cloud Native SBC deployments. Reference the host hardware specifications, where you run your hypervisor, to learn the Ethernet controller in use.
Note:
The Cloud Native SBC does not support media interfaces when media interfaces of different NIC models are attached to the same pod(Signaling/Media/Transcode Engine) in a SR-IOV network mode.Supported Virtual Network Interfaces and Drivers for Paravirtualization
For paravirtualization network mode, the following vNIC types are supported. You can use any make/model NIC card on the host as long as the hypervisor presents it to the virtual machine as one of these vNIC types.
Table 2-2 Virtual Network Interface
| Virtual Network Interface | DPDK Driver | Interface |
|---|---|---|
| KVM (PV) | virtio | Media Interface |
Supported Ethernet Controllers and Drivers for SR-IOV
For accelerated media/signaling using SR-IOV mode use the following card types.
Table 2-3 Ethernet Controller
| Ethernet Controller | Driver | SR-IOV |
