When the IT department of the Calgary Police Service learned about a new programme for body-worn video cameras—that would start with 50 cameras and then grow to over 1,500—it realised its current storage system wouldn’t be able to keep up. The new cameras generated 2.3 gigabytes per hour, or 18.4 gigabytes per shift, meaning the IT team would need to build a new solution to handle the almost one petabyte of video content the department would soon be managing.

The IT team discovered it could meet the new needs and keep costs low by expanding an existing resource and adding auto-tiering software. “One of the coolest things about this project is that it let us expand an existing resource rather than having to start from scratch,” explains Corey Dunn, Technical Services Manager, Calgary Police Service.

The Calgary Police Service upgraded to an enterprise Scalar i6000 library and partitioned it to support multiple applications. One virtual library holds the department’s backups—the second is a video archive.  They selected Quantum Stornext software for archiving because it manages large video files and large numbers of files. It automatically moves data between different storage tiers for extremely high capacity at very low cost. And it creates multiple copies for protection.

“Surveillance data must be kept under our direct control … and it must be protected,” explains Dunn. “But most of it will never be looked at again. So it does not make any sense at all to keep it on live disk. With Stornext, we don’t have to. It lets us use our existing resource, our library, to store all that data at a cost that was far, far lower than any disk-only solution we saw.”

All the body-camera video is ingested directly into a Stornext environment, landing on Quantum high-performance disk where it’s kept for 30 days. In the background, Stornext automatically creates two copies of the files on tape. One stays in the library archive. The second is moved off-site.

Stornext allows users to view any files through a single, file-system interface, whether they are on disk or tape, and it will allow the department to manage nearly a petabyte of data with only 240Tb of disk.

“Stornext’s ability to let us use a small amount of disk …was just what we needed to keep this project’s costs under control. It also gives us protection and long-term retention, something that was a real headache with disk-only systems.”

The new system has proven to be only half the cost of a disk-only approach.  Other advantages include tape archives for long-term security and accessibility, and the Scalar i6000 scales easily using capacity-on-demand, and it can be partitioned to support multiple applications. Optional dual robotics provide redundancy and keep performance high. Military-grade tape encryption and key management provide security. And its Extended Data Life Management proactively ensures that data is readable.

“We know that the recording technology will change and that we need to avoid being locked into one vendor,” says Dunn. “Because it provides a file-system interface, Stornext will work with many different camera systems—that gives us a choice.”
