NetApp’s public-safety solutions provide efficient, high-performance storage for capturing and managing data from video surveillance.
Law enforcement agencies around the country are rapidly adopting body cameras and in-car video surveillance. Advances in IP video surveillance technology have made these cameras less expensive, easier to implement and more capable of capturing high-quality images. These tools can help increase officer safety while providing an impartial view of events.
However, deploying IP video cameras is only the first step in video surveillance adoption. Law enforcement agencies must be prepared to handle the massive amounts of data produced by high-resolution video.
“IP video surveillance places significant burdens on the IT environment — particularly the storage infrastructure,” said Craig Alger, Director of Professional Services, ProSys. “The amount of storage capacity needed depends upon a number of factors, including the number of cameras, the image resolution and frame rate, and the type of video compression technology used. While low-resolution video has fairly modest storage requirements, today’s high-definition, full-motion video streams consume a lot of storage.”
Another factor is data retention. Law enforcement agencies are retaining video surveillance data for months or even years to meet legal and regulatory compliance requirements, further increasing storage demands.
“In order to address these challenges, agencies need cost-efficient storage that can readily scale to accommodate video data growth and enable easy access to video evidence. The storage platform must also be highly reliable and provide the performance needed to support data-intensive video surveillance applications. Robust data protection is required to ensure high levels of data integrity. NetApp’s public safety solutions deliver these capabilities,” Alger said.
Density and Scale
NetApp has developed a validated reference architecture that combines NetApp E-Series storage systems with industry-leading cameras, video management software and video appliances. Video data captured at the “edge” on servers and storage located close to the cameras can be efficiently transferred to the “core” centralized storage used for long-term archival and analytics.
“The NetApp solution is more than just storage — it creates a digital evidence management system that consolidates multiple channels of video data onto a centralized storage platform,” said Alger. “It provides a tightly integrated solution that enables law enforcement agencies to store video evidence efficiently and retrieve it quickly for improved response times during emergencies.”
NetApp E-Series block storage delivers both industry-leading density and cost-effective scalability. By packing multiple petabytes of data into a 19-inch 40U rack, NetApp enables law enforcement agencies to reduce space, power and cooling requirements by 25 percent. NetApp-E-Series storage systems also feature a modular architecture that makes it easy to scale out storage capacity and performance.
“A scale-out architecture is ideal for video surveillance for a number of reasons,” Alger said. “It eliminates the need to overprovision storage and optimizes storage utilization. It also supports video evidence retrieval requirements by allowing both active and archived data to be stored within a single, scalable platform.
“NetApp E-Series storage maximizes these efficiencies to accommodate the ever-increasing growth of video surveillance data. Simply choose the E-Series model that meets your capacity and performance requirements and scale as needed by adding shelves.”
The NetApp E5600 is a hybrid array that leverages conventional disk drives with highly optimized flash storage to deliver the performance and throughput needed for I/O-intensive applications. It delivers up to 825,000 IOPS and sustains 12GBps data transfers to disk. It is supported by NetApp’s SANtricity operating system, which features adaptive caching algorithms for maximum IOPS and throughput.
“In order to support a large number of simultaneous video streams, as well as enable ready access to stored video data, law enforcement agencies need optimized storage performance,” Alger said. “NetApp’s seventh-generation controller technology is field-proven for use with digital evidence management solutions, ensuring that video data can be retrieved quickly.”
The E5600 supports a variety of host and network interface options, and provides greater than “five 9s” reliability with fully redundant I/O paths and automated path failover. SANtricity Storage Management software, Dynamic Disk Pools and thin-provisioning technology make the E5600 easy to deploy and manage. Full-disk encryption and SANtricity Remote Mirroring provide advanced data protection and disaster recovery capabilities.
“Video surveillance has complicated the IT environment in law enforcement agencies. A single high-resolution camera can generate 1TB to 3TB of data per month. Agencies not only need the capacity to support those data volumes but the performance to access evidence efficiently,” said Alger.
“NetApp’s public-safety solutions remove much of the complexity and risk from video surveillance deployments. Agencies gain a flexible, easy-to-manage storage infrastructure with the density and scale to meet video storage demands.”
