Seagate Briefing: Optimizing Video Surveillance System Reliability and Performance How much effect do environmental conditions have on a digital video surveillance system's reliability? For a specific example, the following graph displays the predicted annual failure rate (AFR) of Seagate® SV35 Series™ hard drives as a function of case temperature and power-on hours (POH): AFR AFR vs. Hard Drive Case Temperature 1.80% 1.60% 1.40% 1.20% 1.00% 0.80% 0.60% 0.40% 0.20% 0.00% POH = 8760 POH = 2400 30 40 50 60 70 80 Hard Drive Case Temperature in oC As can be seen, failure rates dramatically increase as drive case temperatures escalate. Dealers and system integrators, installers and even customers must be educated about proper operational conditions for video surveillance equipment if they are to mitigate damage to electronics and other equipment brought on by exposure to harsh conditions. Where can I learn more about proper operational conditions for my digital surveillance equipment? Seagate provides partners and customers with a range of educational tools that can be used to help inform people on drive opportunities, risk areas and best practices. Seagate maintains a library of technology papers that can aid in this educational effort. Are there other factors beyond the operational environment that impact digital surveillance system reliability? Proper enclosure or chassis design is a key factor in achieving optimal reliability. Electronic systems must be housed in well-designed enclosures specifically engineered for proper temperature management and vibration control or compensation. Because hard drives are critical components in digital surveillance systems, Seagate has developed its Design Services Center, which provides dedicated engineering expertise to help customers evaluate system enclosures for best practices in temperature and vibration/shock management. What is Seagate doing to help optimize hard drive reliability in digital surveillance systems? Seagate philosophy on improving products for a given storage segment is one of engagement. Intimate knowledge about the specific needs of a given storage segment is only achieved by actively engaging with customers and partners on a focused, low-level basis. This philosophy is reflected in the introduction of the SV35 Series drive, the first drive specifically designed and optimized for the video surveillance market. The SV35 Series drive represents a significant investment by Seagate in the engineering and support resources for a growing market. Such commitments result in valuable learning and advances in technology, functionality, performance and reliability that simply don't occur as quickly without a focused approached. How does the SV35 Series drive differ from other Seagate products? It is a well-known fact that IT component manufacturers design and market products by usage model or segment. Desktop, notebook, server and emerging consumer electronics have been the platforms manufacturers design around from processors to hard drives. But Seagate recognized that the surveillance DVR does not fit any of these platforms, forcing surveillance customers to choose the "best-fit" hard drive product for their solutions. Seagate SV35 Series "purpose-built" drives were developed to specifically address the needs of the surveillance DVR market. Below is a comparison of several Seagate drive products specialized to service different segment niches. 2
