The DFS Deutsche Flugsicherung GmbH (German Air navigation Services) is a government-owned company responsible for all air traffic control in Germany. With headquarters in Langen, near Frankfurt, DFS employs 5,200 staff, runs operations at four control centres and 19 international and regional airports across the country..

Because system availability is vital to the safe handling of air traffic, DFS has implemented a fail-over solution by running Heartbeat on a pair of clustered servers at all international airports in Germany. The solution consists of two servers equipped with HW-Raid, DRBD and Heartbeat 2.x as cluster software. The application on these servers delivers important weather, runway and airport information to the air traffic controllers at 19 international Airports in Germany.

We have ported the application from a proprietary UNIX/Cluster Solution to Linux and Heartbeat and saved a considerable amount of money while maintaining the same level of reliability and gaining flexibility by using the Heartbeat/DRBD combination.

Our Wireless Data Manager (WDM) handles private-MMP and public-GPRS data sent from our trucks worldwide. We have 150+ WDM boxes distributed in most countries. Their primary use is to serve handheld devices for package delivery. I chose HA so that upstream hosts can connect to a single IP address instead of using clustering. This was after much discussion of other solutions such as load balancing (LB), and disaster recovery (DR).

We have a routing table which we could have shared using DRBD, but we chose instead to use anonymous-ftp for three reasons: 1) we are behind a firewall, 2) less key management, 3) we control the read/writes to this shared file.

Linux-HA (heartbeat) has been embraced by our group since the user interface is simple, solid, extendable and gives 15-second failover performance. We will probably add fencing via a STONITH device in the near future.

MAN Nutzfahrzeuge AG is one of the most important subsidiary companies of the MAN AG. Our business is it to build trucks and busses, which are shipped to the whole world. IT services and infrastructure across the group are consolidated in our data processing centers.

We are now running Heartbeat in conjunction with DRBD in production since the beginning of 2003. This stable solution, known from expierence, makes it possible to provide highly available services and to guarantee this fact to our customers in service level agreements. The Heartbeat cluster solution is one part of our three tier architecture, with a loadbalanced cluster in front and an Oracle DB at the backend. It provides the application server for our central document management system which powers the whole intranet of our enterprise. Besides that the HA environment consists of an NFS server and an administration tool called CfEngine. For each of these services we configured an own resource group with its own IP addresses, filesystems and so on.

Thanks to the Heartbeat team for this great piece of software and the support given through the mailing list. Keep it up!

SideStep uses heartbeat in an LVS cluster with mon & ldirectord. Future plans for linux clusters include file servers & various other projects. Great product.

Our connection to the internet is handled by 2 Debian GNU/Linux servers(stable edition) communicating with heartbeat from Debian repository. In case of a failure at our main transparent proxy/internet gateway server, the backup server takes over the proxy's IP address, thus providing the port with a reliable connection to the internet.

Using a keepalive of 1 second and deadtime of 3 seconds, tests have shown that in case of a failure, the network connection can be offline for as little as half a second or for as long as 5 seconds, for the IP takeover change to finish.
