Evidian SafeKit
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.
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.
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.

What are the needs in terms of high availability?
A short video that presents the needs in terms of high availability.
High availability for dummies with Microsoft Paint :-)
A video showing how SafeKit works with Microsoft Paint.
Software cluster versus hardware cluster
This video compares the SafeKit clustering software versus hardware clustering solutions.
Business Continuity and Disaster Recovery with a single software
This video shows how business continuity and disaster recovery can be simply implemented with SafeKit without the need of a replicated SAN.
High availability cluster between a laptop and a netbook
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.
Hyper-V Replication and Automatic Failover of VM Checkpoints and Settings
This video shows replication of VM checkpoints and settings (another video shows the replication of full VMs).
Active-active cluster with real-time replication
This video shows an active-active cluster with real-time replication built with 2 SafeKit mirror modules.
Clustering with load balancing and mirroring
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.
Synchronous replication vs asynchronous replication
This video shows that no transactions are lost with synchronous replication on Microsoft Message Queuing while data are lost with asynchronous replication.
Virtual IP address with load balancing and failover
This video shows how a virtual IP address with load balancing and failover works on Apache.
Heartbeat, failover, quorum
This video shows how the split brain problem is solved for a cluster in a network isolation situation on the Microsoft SQL Server application.
Automatic failback after a failover
This video shows replication of Microsoft Message Queuing with an automatic failback after a failover. Data are resynchronized while being modified.
Master / slaves dependency between modules
This video shows a master / slaves dependency between modules in a SafeKit high availability cluster.
Partners, the success with SafeKit
This platform agnostic solution is ideal for a partner reselling a critical application and who wants to provide a redundancy and high availability option easy to deploy to many customers.
With many references in many countries won by partners, SafeKit has proven to be the easiest solution to implement for redundancy and high availability of building management, video management, access control, SCADA software...

Advanced clustering architectures
Several modules can be deployed on the same cluster. Thus, advanced clustering architectures can be implemented:
- the farm+mirror cluster built by deploying a farm module and a mirror module on the same cluster,
- the active/active cluster with replication built by deploying several mirror modules on 2 servers,
- the Hyper-V cluster or KVM cluster with real-time replication and failover of full virtual machines between 2 active hypervisors,
- the N-1 cluster built by deploying N mirror modules on N+1 servers.
