An IP you can transfer between servers

When you have a dedicated server with OVH, you can get failover IPs to host your projects, SSL certificates, etc. The failover IP can be switched from one server to another in a few seconds. This provides you with an uninterrupted hosting solution, and helps to overcome the headache of hardware failure, system overruns and all kinds of infrastructure problems. In order to take full advantage of the failover IP's potential, your hosting solutions must be configured with the failover IP (as opposed to the server's static IP).
So if you switch the failover IP from one server to another, you keep the entire configuration linked to that failover IP. You are responsible for copying your projects and configuration files from one server to the other. Since the configuration files are linked to the failover IP, and therefore the data and configurations remain the same, everything will keep working once you have switched the failover IP to the new server. You don't need to reconfigure all your projects with your new server's static IP.

Server change/Server upgrade

Your projects are hosted on dedicated server A (fixed IP A) and are configured with failover IP Z.


Failover IP if your dedicated server is changed

You may order a new server if server A isn't powerful enough to support your projects. Here it is described as server B, with fixed IP B.

Failover IP if your dedicated server is changed

You need to make copies of your projects and configuration files from server A to B. Then...

... you can change the routing of failover IP Z from server A to server B. As your projects' data and your configuration files are linked to the failover IP, they will continue to work on server B. You don't need to make any configuration changes (DNS, APACHE, SMTP, POP3, MySQL ...).

Working in a main server and a backup server

You have two servers: A and B. Server A is your main server, server B is your backup server.
Your projects are configured on failover IP Z, routed to server A. You can regularly copy your projects from server A to B.

Failover IP when a hardware failure causes the service to switch servers

Failover IP when a hardware failure causes the service to switch servers

Lorsque vous avez le serveur A en panne, vous basculez le routage de l'IP fail-over Z du serveur A vers le serveur B. Le serveur B est de nouveau opérationnel. Vous avez le temps de réparer le serveur A.

Lorsque le serveur A est réparé, vous copiez les données du serveur B vers le serveur A puis vous rebasculez le routage de l'IP fail-over Z du serveur B vers le serveur A. Le serveur A est de nouveau opérationnel.

The advantage of this solution is twofold:

  • It enables you to back up the data on server A
  • You can use server B of server A goes down

Hosting multiple projects

If you host multiple websites, you can host them on server A by using two failover IPs. Some of your websites will be hosted on failover IP Y and the rest on failover IP Z.

Failover IP in the case of a subscription to an additional server

Lorsque votre serveur A n'est plus assez puissant pour héberger les sites des IP fail-over Y et Z, vous pouvez prendre un nouveau serveur B, puis basculer uniquement le routage l'IP fail-over Z sur le serveur B. Le serveur A étant délesté d'une partie de son travail, il est de nouveau opérationnel.

Domaine applicable au Fail-Over

Vous pouvez basculer des IP depuis un serveur vers un autre serveur dans un même datacenter. Le basculement d'IP entre des datacenters différents est permis si les datacenters sont situés dans le même pays.
