This tutorial shows how to use the SafeKit console the first time after the download of the SafeKit package. You will see how to set-up the IP addresses of the servers in the cluster, how to set a replicated directory and a virtual IP address. The Configuration tab is demonstrated.
SafeKit is making real-time replication of data. This tutorial shows how to set a replication network in the cluster management console. The Configuration tab is demonstrated.
The heartbeat timeout determines how much time a secondary server waits when the primary server crashes before restarting an application. The default timeout value is 30 seconds and is set to 15 seconds in this videos. The Advanced Configuration tab of the cluster management console is demonstrated.
This tutorial shows how to add a ping checker to an external router in a high availability module. If the router cannot be accessed by a server, the module goes to the WAIT red state on this server, When the router is accessible, the module on the server is automatically restarted and goes to a green state. The Advanced Configuration tab of the cluster management console is demonstrated in this video.
A short video that presents the needs in terms of high availability.
A video showing how SafeKit works with Microsoft Paint.
This video compares the SafeKit clustering software versus hardware clustering solutions.
This video shows how business continuity and disaster recovery can be simply implemented with SafeKit without the need of a replicated SAN.
Understand in 5 minutes the simplicity of the SafeKit high availability solution and the resulting cost-savings with a demonstration of a Windows cluster implemented by a laptop and a netbook.
This video shows replication of VM checkpoints and settings (another video shows the replication of full VMs).
This video shows an active-active cluster with real-time replication built with 2 SafeKit mirror modules.
This video shows a combination of load balancing, replication and failover with a farm module and a mirror module. A failover dependency between the farm and the mirror modules is demonstrated.
This video shows that no transactions are lost with synchronous replication on Microsoft Message Queuing while data are lost with asynchronous replication.
This video shows how a virtual IP address with load balancing and failover works on Apache.
This video shows how the split brain problem is solved for a cluster in a network isolation situation on the Microsoft SQL Server application.
This video shows replication of Microsoft Message Queuing with an automatic failback after a failover. Data are resynchronized while being modified.
This video shows a master / slaves dependency between modules in a SafeKit high availability cluster.
This platform agnostic solution is ideal for a partner with a critical application and who wants to provide a high availability option easy to deploy to many customers.
This clustering solution is also recognized as the simplest to implement by our partners.

Several modules can be deployed on the same cluster. Thus, advanced clustering architectures can be implemented:
