DISASTER RECOVERY HDD with no damage after restart to more severe disturbances. It was found that the main cause of these problems was the high noise level caused by the discharge of the agent during the extinguishing process. To answer this challenge, Silent Extinguishing Technology is now available to ensure quiet and safe extinguishing in data centres and server rooms. This technology reliably protects IT operations and minimizes the risk of business interruptions following a fire extinguishing system discharge. Integrated Solutions Effective fire safety systems are a fundamental requirement in achieving maximum system uptime and availability. the cooling system is shut down after pre-alarm while the point-type detectors verify the presence of combustion and trigger the extinguishing system. ASD systems are available that are based on a dual wavelength technology to verify that particles aspirated in very low concentrations actually are smoke from a fire. Full integration of the device into the fire safety or management system ensures the safest operation possible because all the ASD warnings and possible maintenance messages are available at the management level so corrective measures can be taken. Efficient Extinguishing The most important factor when designing an extinguishing system in a data centre environment is to make sure that the chosen agent extinguishes the fire without harming sensitive electronic equipment. For this reason, water should be avoided at all times. Furthermore, the agent must be environmentally friendly, safe for people working in the protected area, and not harm the HDDs in operation. Both clean agent and inert gas systems can be excellent and reliable systems if they are properly designed and commissioned. Even though dry extinguishing systems are the best choice to protect data centres, the latest technological findings show that in very rare cases computers and HDDs can face problems after the extinguishing process has been triggered. These problems may range from automatic shutdown of a 12 NETCOMMS europe Volume V Issue 5 2015 Electronic security and safety solutions can help protect a data centre and in doing so protect an organisation’s application availability, its confidentiality, its integrity and, ultimately, its ability to function. Integration of security and safety measures is one of the prime methods of enhancing business continuity through protection of business-critical data. Central management of operational systems provides a more efficient and dynamic use of resources, focusing them when and where they are needed. Fire safety and security can be integrated through danger management stations. This allows for centralized supervision and alarm handling from a number of different sources, including fire detection, video surveillance, access control and intrusion detection. The benefits of integrating fire safety and security are numerous: video surveillance allows the danger zone to be viewed immediately, offering a visual means of verifying and assessing the situation; integrated access control provides monitoring of escape routes and the means to quickly open or close doors, an important part of the evacuation process; integrated intrusion detection means that data and electronic equipment is protected not only from the threat of fire, but also against unobserved theft or sabotage. All of this through a single, centralised station that guides personnel through the step-bystep processes to be followed in the event of an incident. This integrated view of what is happening not only helps to resolve an incident, but also provides the capability to learn from incidents, which is crucial in enabling process adaptation in the very dynamic risk landscapes which characterise today’s business environments. Although safety and security are not a direct part of IT operations, they definitely help to ensure the business continuity environment of a data centre. The Best Solution To ensure the highest possible safety and security, it is important to control the interfaces and use the latest scientific findings for the best solution. Systems with real interoperability from a single source are therefore the preferable option in such a mission critical environment as a data centre, requiring
