SIOS Technology provides high availability (HA) clustering solutions to protect critical Building Management and Security (BMS) systems like HVAC, access control, and video surveillance from downtime and failures. Unlike traditional clustering that relies on shared storage, SIOS’s SANless clustering eliminates single points of failure, reduces complexity, and supports flexible deployment across Windows, Linux, physical, virtual, and cloud environments. Proven in complex environments like stadiums and airports, SIOS ensures uninterrupted BMS operations, near-zero downtime patch management, and continuous protection for essential facility systems.
