OVHcloud Link Aggregation

Get a redundant, high-bandwidth private network for critical applications and distributed infrastructures

To ensure service continuity, redundancy mechanisms are already implemented on most network infrastructures, but stop at switches.

OVHcloud Link Aggregation (OLA) goes even further. You can use it to aggregate your server’s physical network links (public and private), and group them together as a single virtual link attached to the private network. You can then increase your server’s availability and private bandwidth.

  • This technology is exclusive to OVHcloud for bare-metal products: in just a few clicks, you can get optimal redundancy and physical network link aggregation.
  • You get a high-speed private network, with up to 50Gbps unlimited and guaranteed on the High Grade* range.
  • Service included and free with Infrastructure, Scale and High Grade servers. Simply enable the feature via the OVHcloud Control Panel.

Improved availability

You can use OLA technology to aggregate all physical network links on your server — up to four links on the Scale and High Grade ranges. This way, you can avoid any potential service interruptions resulting from the loss of one or more network links — so you get optimal availability and resilience for your infrastructure.

Very high bandwidth

By enabling OLA on the new Scale and High Grade ranges, you can aggregate the four 25G physical network links. You can then get up to 50Gbps guaranteed private bandwidth*. In addition to this throughput capacity, both ingress and egress traffic are always unlimited** at OVHcloud.

*See the compatibility table for the ranges.
**Excludes datacentres located in the Asia-Pacific region.

Maximum security

With OLA technology, you can aggregate interfaces by connecting them to the private network. Your infrastructure is more secure, as it is isolated from the public network. It can offer you an additional layer to preserve your data.

Infrastructure Servers

The servers in the Infrastructure range have a private interface, and a public one. With OLA, you can aggregate the two physical network links to the private network. You can reach speeds of up to 10Gbps with the combined benefits of the vRack private network and OVHcloud Link Aggregation technology.

Scale and High Grade Servers

Scale and High Grade servers have four physical network links by default: two public links, and two private links. With OLA technology, you can quickly aggregate both private and public physical network links.

For maximum redundancy, you can aggregate the four server links on the private network, and isolate your infrastructure from the public network. By doing this, you can get an unlimited, guaranteed 25Gbps high-speed private network for Scale, and 50Gbps unlimited and guaranteed for High Grade.


What are the requirements for enabling OLA?

First, the feature needs to be enabled from the OVHcloud Control Panel, or via an API. Next, the network interface aggregation needs to be configured on the server’s operating system.

Which dedicated servers are compatible with the OVHcloud Link Aggregation feature?

Our Infrastructure, Scale and High Grade ranges are compatible. With Infrastructure dedicated servers, you can aggregate two physical network links. With the Scale and High Grade ranges, you can aggregate up to four physical network links.

Is the OLA feature free?

Yes, this is a free feature included with all Infrastructure, Scale and High Grade servers. You just need to enable it via the OVHcloud Control Panel.

If I aggregate all my links on the private network, how do I access my server?

By enabling OLA, your server is isolated from the public network. As a result, you will need to use the IPMI tool to access your server. Monitoring will also be disabled for your server.
