Tutorials on the console

The SafeKit high availability cluster management console

First use of SafeKit

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.

Edit failover scripts

In a high availability cluster, the critical application must restart automatically. This tutorial shows how to edit start and stop scripts in the SafeKit console to include start and stop of the critical application. The Configuration tab is demonstrated.

Monitoring a high availability cluster

This tutorial shows what happens when a server crashes in the SafeKit cluster management console. The Monitoring tab is demonstrated.

Set a replication network

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.

Troubleshooting with the cluster management console

When the SafeKit console presents a red server, it means that the solution is no more high available. This tutorial shows how to manage a problem in a cluster and how to restart a high availability module. The Control tab is demonstrated.

Set a heartbeat timeout

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.

Add a ping checker

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.

Real-time file replication and application failover example with Microsoft Paint (mirror module)

This tutorial shows how to implement easily real-time file replication and application failover on the example of Microsoft Paint.
For more information on the implementation, see how Evidian SafeKit implements simply real-time file replication and application failover? Example on Microsoft Paint.

Apache load balancing and failover (farm module)

This tutorial shows how to implement easily Apache load balancing and failover inside a farm cluster. This demonstration works on Windows, Linux or AIX. Configuration, Apache load balancing ans failover are demonstrated in this video.
For more information on the implementation, see how Evidian SafeKit implements simply a farm cluster with Apache load balancing and failover on Windows, Linux or AIX?

Microsoft SQL Server 2012 cluster with replication and failover (mirror module)

This tutorial shows how to implement easily a Microsoft SQL Server 2012 cluster.
Configuration, real-time database replication and automatic failover are demonstrated in this video.
For more infomation on the implementation, see how Evidian SafeKit implements simply a Microsoft SQL Server 2012 cluster with replication and failover?

Hyper-V 2012 R2 cluster with replication, failover and load balancing (N mirror modules)

This tutorial shows how to implement easily a Hyper-V 2012 R2 cluster. Configuration, real-time VM replication, automatic failover, migration of a VM and load balancing of VMs are demonstrated in this video on 2 VMs.
For more information on the implementation, see how Evidian SafeKit implements simply a Hyper-V cluster 2012 R2 with replication, failover and load balancing of VMs?
