OVHcloud Link Aggregation

What is OVHcloud Link Aggregation?

With the OVHcloud Link Aggregation (OLA) feature, you will get continuous uptime for your services and a very high bandwidth network for critical applications and distributed infrastructures. This technology is exclusive to the world of bare metal. You can use it to create a high-availability infrastructure with up to 10Gbps* of bandwidth between servers.

You can enable this option via the OVHcloud Control Panel in just a few clicks, to boost your server’s availability.

OVHcloud Link Aggregation technology was designed by our teams to increase the availability of dedicated servers that host critical applications.

Redundancy mechanisms have existed for a number of years, and are implemented on most network infrastructures. But these are limited at an active element level, i.e. switches. We have chosen to go even further, and extend this redundancy mechanism to your dedicated servers.

*You can reach 10Gbps by signing up to the "vRack additional private bandwidth" and "OVHcloud Link Aggregation" options.

Improved availability

You get a highly available dedicated server, with a double connection. This means you avoid any potential service interruptions linked to one of the two network links going down.

Very high bandwidth

By setting the function to nominal and enabling the OLA feature, your bandwidth will be doubled. By default, you will have two 2Gbps links on the vRack private network.

Maximum security

Enabling the OLA feature automatically isolates your dedicated server from the public network, meaning that it cannot be accessed publicly via the internet.

How does it work?

Once you have enabled this feature on your server, you can group your two network links (public and private) into a single link. You automatically get a redundant virtual private link that is very high-frequency. Your server will also be completely isolated from the public network, blocking any attempts to connect via the internet as a result. By setting the function to nominal, you can use the two network links to transfer your data between servers. If one of the two links goes down, traffic is automatically redirected to the working link without any service interruptions. This means that your users won’t experience any downtime.
