− | == Mellanox Quantum Plugin ==
| |
− | Openstack Mellanox Quantum plugin supports Mellanox embedded switch functionality as part of the VPI (Ethernet/InfiniBand) HCA.
| |
− | Mellanox Quantum Plugin allows hardware vNICs (based on SR-IOV Virtual Functions) per each Virtual Machine vNIC to have its unique
| |
− | connectivity, security, and QoS attributes. Hardware vNICs can be mapped to the guest VMs through para-virtualization (using a Tap device), or directly as a Virtual PCI device to the guest, allowing higher performance and advanced features such as RDMA.
| |
| | | |
− | Hardware based switching, provides better performance, functionality, and security/isolation for virtual cloud environments.
| + | = Mellanox Quantum Plugin = |
− | Future versions of the plug-in will include OpenFlow API to control and monitor the embedded switch and vNICs functionality
| + | Mellanox support OpenStack Folsom/Grizzly releases with an open source networking components through Quantum, It delivers higher compute and storage performance and additional functionality such as NIC based switching to provide better security and isolation for virtual cloud environment. |
− | | |
− | This plugin is implemented according to Plugin-Agent pattern.

| |
− | * Openstack Mellanox Quantum Plugin implements the Quantum v2.0 API.
| |
− | * Mellanox Quantum Plugin processes the Quantum API calls and manages network segmentation ID allocation.
| |
− | * The plugin uses Databsase to store configuration and allocation mapping.
| |
− | * The plugin maintains compatibility to Linux Bridge Plugin support DHCP and L3 Agents by running L2 Linux Bridge Agent on Network Node.
| |
− | * Mellanox Openstack Quantum Agent (L2 Agent) should run on each compute node.
| |
− | * Agent should apply VIF connectivity based on mapping between a VIF (VM vNIC) and Embedded Switch port.
