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. ## Key players list in BMS The key players in BMS are: * Honeywell International Inc. (US) * Johnson Controls (Ireland) * Schneider Electric (France) * Siemens (Germany) * United Technologies (US) * ABB (Sweden) * Azbil Corporation (Japan) * Delta Controls (India) * LARSEN & TOUBRO LIMITED (India) * Mitsubishi Electric Corporation (Japan) * Robert Bosch GmbH (Germany) * Singapore Technologies Engineering Ltd (Singapore) * DEXMA SENSORS, S.L. (Spain) * Eagle Technology (India) * Legrand (France) * Lutron Electronics Co., Inc. (US) * Technovator International Limited (Singapore) * Airedale Air Conditioning (UK) * BuildingIQ (US) * ACUITY BRANDS LIGHTING, INC. (US) * GridPoint (US) ## 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](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20168%2074'%3E%3C/svg%3E)![Redundancy at the application level for a BMS software](https://safekit.eviden.com/wp-content/uploads/2023/02/application-ha-4.png) This solution requires a technical understanding of the application. You need to define which services to restart, specify the application folders to replicate, and configure a virtual IP address for failover. But this solution is platform agnostic and works with applications inside physical machines, virtual machines, in the Cloud. Any hypervisor is supported (VMware, Hyper-V...). ### Examples * Video management: [Milestone (Management, SQL, Log, Event)/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/milestone-xprotect-corporate-high-availability-synchronous-replication-failover/) * Video management: [Genetec (SQL)/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/genetec-sql-server-the-simplest-high-availability-cluster-with-synchronous-replication-and-failover-between-two-redundant-servers/) * Access control: [Nedap (AEOS, SQL)/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/nedap-high-availability-synchronous-replication-failover/) * New application (define services to restart, application folders to replicate, a virtual IP address for failover): [Windows](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/windows-high-availability-software-synchronous-replication-failover/), [Linux](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/linux-high-availability-software-synchronous-replication-failover/) ### 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](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%20184%20107'%3E%3C/svg%3E)![Redundancy at the virtual machine level for a BMS software](https://safekit.eviden.com/wp-content/uploads/2023/02/vm-ha-4.png) The advantage of this solution is that it does not require a technical understanding of the application; you only need to define the location of the VM files where the application is installed. This solution is generic for any BMS software. However, it works only 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. ### Examples * Building management: [Siemens Desigo CC/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/siemens-desigo-cc-redundancy-high-availability-cluster-active-active/) * Video management and access control: [Siemens Siveillance suite/SafeKit](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/siemens-siveillance-redundancy-high-availability-cluster-active-active/) * New application (define the location of the VM files folder where the application is installed): [Windows/Hyper-V](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/hyper-v-replication-automatic-failover-load-balancing/), [Linux/KVM](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/linux-kvm-high-availability-replication-automatic-failover-load-balancing/) More comparison between [VM HA vs Application HA](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/vm-ha-vs-application-ha/#vm-ha-vs-application-ha) ## SafeKit, a recognized solution on the security market ### Milestone has chosen SafeKit SafeKit is deployed in 30+ countries with the video management software of Milestone. [SafeKit is validated by Milestone](https://www.milestonesys.com/technology-partner-finder/evidian/milestone-redundancy-and-high-availability/) for redundancy and high availability of the management server. SafeKit is the best solution because it is purely software, completely hardware-agnostic. ### Solution preferred by Siemens SafeKit is available in the [Siemens marketplace](https://xcelerator.siemens.com/global/en/all-offerings/products/safekit.html) with its [Siveillance suite](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/siemens-siveillance-redundancy-high-availability-cluster-active-active/) (video and access control) and with its SCADA software: [Desigo CC](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/siemens-desigo-cc-redundancy-high-availability-cluster-active-active/) (building management), [SIMATIC WinCC](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/siemens-simatic-wincc-redundancy-high-availability-cluster-active-active/), [SIMATIC PCS 7](https://safekit.eviden.com/products/high-availability-software-for-application-clustering/siemens-simatic-pcs-7-redundancy-high-availability-cluster-active-active/). SafeKit is deployed by Siemens in Australia, France, the Netherlands, Qatar, Switzerland, the UAE, the UK, the US. ### SafeKit recommended by Nedap Nedap, a key player in physical access control, recommends SafeKit for redundancy and high availability of its AEOS application.
