Building Management System Software (BMS)

Redundancy and high availability with Evidian SafeKit

What is a building management
system (BMS)?

A building management system (BMS) brings the automatic centralized control of building's HVAC (heating, ventilation and air conditioning), electrical, lighting...

A building management system increases safety for building residents, reduces energy consumption and reduces operating and maintenance costs.

Why a BMS software
is critical?

A BMS software controls fire system, electrical distribution panels, water consumption, air conditioning systems, lighting control.

Life safety in the building is directly associated to the correct execution of the BMS software.

And that’s why, the system must be always available for building operators who must react immediately to the slightest incident.

SafeKit brings two solutions for redundancy and high availability of a BMS 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 BMS 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...).


Redundancy and high availability at the virtual machine level

In this type of solution, the BMS 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 BMS software

The advantage of this solution is that there is no restart scripts to write per application. This solution is generic for any BMS 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.


More comparison between VM HA vs Application HA


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 (same as 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 guide
