================
|
|
|
|
Beginning with version 5.1, Fuel can configure Mellanox ConnectX-3 Pro network
|
|
adapters to accelerate the performance of compute and storage traffic.
|
|
This implements the following performance enhancements:
|
|
- Compute nodes use SR-IOV based networking.
|
|
- Cinder nodes use iSER block storage as the iSCSI transport rather than the
|
|
default iSCSI over TCP.
|
|
|
|
These features reduce CPU overhead, boost throughput, reduce latency, and
|
|
enable network traffic to bypass the software switch layer (e.g. Open vSwitch).
|
|
Starting with version 6.1, Mellanox plugin can deploy those features over
|
|
Infiniband network as well.
|
|
|
|
*Requirements*
|
|
|
|
The Mellanox ConnectX-3 Pro adapters family supports up to 40/56GbE.
|
|
To reach 56 GbE speed in your network with ConnectX-3 Pro adapters, you must
|
|
use Mellanox Ethernet / Infiniband switches (e.g. SX1036) with the additional
|
|
56GbE license. The switch ports should be configured specifically to use 56GbE
|
|
speed. No additional configuration is required on the adapter side.
|
|
For additional information about how to run in 56GbE speed, see [HowTo
|
|
Configure 56GbE Link on Mellanox Adapters and Switches](http://community.mellanox.com/docs/DOC-1460).
|
|
|
|
For detailed setup configuration and BOM (Bill of Material) requirements please see
|
|
[Fuel Ethernet cloud details](https://community.mellanox.com/docs/DOC-1474) or
|
|
[Fuel Infiniband cloud details](https://community.mellanox.com/docs/DOC-2036).
|
|
|
|
*Limitations*
|
|
|
|
- OVS bonding and Mellanox SR-IOV based networking over the Mellanox ConnectX-3 Pro
|
|
adapter family are not supported.
|
|
- In order to use the SR-IOV feature, one should choose KVM hypervisor and
|
|
"Neutron with Vlan segmentation" in the Network settings tab.
