The document discusses the challenges of proprietary control software in data centers, emphasizing the need for modern solutions due to outdated systems and complex architectures. It presents OBIX, an open-source project focused on building control systems using XML and web services, enabling real-time access and vendor independence. The implementation of OBIX offers scalable architectures, remote access control, and real-time monitoring capabilities for enhanced operational efficiency.

The Challenge
•Data Centre's are one of the last bastions of proprietary control software
•SCADA (Supervisory Control and Data Acquisition) and BMS (Building Management Systems) have not progressed in many years
•Many are based on obsolete operating systems
•Control and telemetry systems are usually very vendor specific and hard to customise

Complex Architectures
•Lots of old serial commsbased devices
•RS-232, RS-485, Modbus are very common
•Some proprietary protocols
•Demanding requirements

The Solution
•oBIXbegan its life in April of 2003 as theCABA XML/Web Services Guideline Committee
•oBIXhas taken on a life of its own, currently a technical committee at the Organisation for the Advancement of Structured Information Standards (OASIS)
•OASISis a global, non-profit consortium that focuses on the development and adoption of e-business standards

oBIXImplementation
•Multilayer distributed (scalable) architecture with tiny footprint
•Delivering real-time power monitoring and telemetry data
•Maintains privacy / security (customer exclusive servers)
•Enables remote access control (locking / unlocking racks)
•Receive real-time data to enable real-time decision making
•Sync adapters filter and distribute the data in real-time

Access Control
•Remote locking with front and rear door powered by oBIXprovides access, security and control
•The virtual and physical access levels of users can be managed and controlled by administrators
•Provide time frame specific records of any action, virtual or physical within the allocated data spaces
•Watch processes provide inter- server messaging
