SCADA Software

Redundancy and high availability with Evidian SafeKit

What is a SCADA
system?

SCADA systems make it possible to control industrial processes, to interact directly with devices such as sensors, valves, pumps, motors, through human-machine interface software.

Why a SCADA software
is critical?

If the SCADA software is down, the production of a factory stops.

That’s why, the SCADA software must be always available for operators who must react immediately to the slightest incident.

SafeKit brings two solutions for redundancy and high availability of a SCADA software

Redundancy and high availability at the application level

In this type of solution, only application data are replicated. And only the application is restared in case of failure.

Redundancy at the application level for a SCADA software

With this solution, restart scripts must be written to restart the application. This solution is platform agnostic and works with applications inside physical machines, virtual machines, in the Cloud. Any hypervisor is supported (VMware, Hyper-V...).

  • Solution for a new application (restart scripts to write): Windows, Linux

Redundancy and high availability at the virtual machine level

In this type of solution, the SCADA software is put inside a virtual machine. The full Virtual Machine (VM) is replicated and restarted (Application + OS).

Redundancy at the virtual machine level for a SCADA software

The advantage of this solution is that there is no restart scripts to write per application. This solution is generic for any SCADA software. It works with Windows/Hyper-V and Linux/KVM but not with VMware. This is an active/active solution with several virtual machines replicated and restarted between two nodes.

Comparison

Built-in Hyper-V replication

Built-in Hyper-V replication

  • Asynchronous replication => data loss
  • Manual failover (no automatic failover)
  • Not a high availability solution

Microsoft clustering (idem with VMware HA)

Microsoft clustering / Hyper-V solution

  • Requires a shared disk
  • Price of the shared disk and its installation (SAN, iSCSI)
  • Configuration complexity of Windows failover cluster (AD…)
  • Remote sites = replicated storage

Evidian SafeKit

SafeKit / Hyper-V solution

  • Simple and economical
  • Synchronous replication => no data loss
  • Automatic failover and failback
  • No shared disk
  • Free trial and quick installation here
