SAN for Video Surveillance Systems
It goes without saying—every video surveillance system needs efficient and reliable data storage. But that is not to say every video system requires large-scale, shared network storage to function optimally. High-performance video appliance NVRs built for video capture, analysis and recording often adequately support many small- to mid-size video surveillance environments. However, there are installations where a Storage Area Network (SAN) infrastructure brings new and needed levels of flexibility, scalability and protection.
Enterprise-class surveillance environments utilize large numbers of high-resolution cameras and extended video retention times, often 30-90 days, thus requiring a storage solution that is more robust and expandable than traditional NVRs. SAN is an optimal alternative. Here’s why.
At a certain point in an enterprise surveillance deployment’s growth, the capabilities and cost-effectiveness of a typical NVR solution are simply exceeded. SANs offer a more robust architecture that has the ability to scale over time, making it an excellent fit for a security application that needs room to expand, as business grows, and camera technology evolves.
A SAN enables enterprise-level security deployments to integrate multiple recording appliance (NVR) units into one shared storage network, using iSCSI or Fiber Channel connectivity through a network switch. All this happens at the block level for video recording and data accessibility, such that the recording appliances will register the storage allocated by the SAN as if it were directly connected. This way, the file system is maintained by that recording appliance. By using a SAN, all servers can access the storage network as a shared resource. This guarantees speed, efficiency, and simplified data management.
As surveillance infrastructure increases, storage systems or expansion units may be easily added over time to increase capacity, without an administrator having to re-architect the camera to NVR network. SAN architecture allows for greater flexibility to change VMS software or upgrade hardware without heavy lifting. SAN systems can also increase redundancy, eliminating a single point of failure often characteristic of simple NVR only environments.
Customers who use SAN architecture come in all shapes and sizes. Here are three examples of surveillance environments where customers should consider using a SAN:
At the end of the day, these three surveillance environment examples are unique; but SAN is optimized to effectively and reliable manage video storage for all of them.
Not all SAN storage options are the same. It matters that enterprise customers partner with manufacturers with a track record of success. A prime example is Arxys—whose data protection and data analytics appliances are purpose-built for video surveillance—and Seagate Technology—whose enterprise storage systems are optimized for demanding workloads and scalability. Arxys and Seagate have recently come together to deliver a SAN storage option specially designed for large enterprise video surveillance customers.
Specifically, Arxys’ DataX Prime X584E solution, which uses the Seagate Exos X 5U84 system, is built to support up to 1.3 petabytes (PB) of data in a single 5U enclosure. Users can easily accommodate data proliferation and expand the solution by adding three additional Exos X 5U84 systems for a total capacity of 4PB. Designed for advanced throughputs and read/write capabilities and up to 99.99% availability, this solution is ideal for demanding streaming environments and built for accessibility and scalability.
The Data X Prime X584E solution also features Seagate’s Advanced Distributed Automatic Protection Technology (ADAPT), which is based on parallel architecture that employs intelligent analytics to anticipate and respond to potential system failures. Put simply, ADAPT ensures data is dispersed across multiple drives, allocating more resources for rebuilds. This shortens the time needed for rebuilds, reduces the risk of data unavailability, and minimizes system downtime for customers. As a result, ADAPT can eliminate up to 95 percent of performance degradation during a disk drive rebuild when compared to traditional RAID solutions. Additionally, for heightened data protection, the Data X Prime X584E solution also includes Seagate Secure™ cybersecurity features, which satisfy both Federal Information Processing Standards and Trade Act Agreement requirements.
In a world where data is becoming increasingly complex, consider deploying a SAN option to enhance recording throughput, simplify data management, and future proof your system. To get the most out of your surveillance system, choose storage partners whose technology is engineered to lower the total cost of ownership.
