Input: Question: What year was the tech company that made the products used by U2 on their concerts found? Passage:The concerts were digitally recorded by 28 HD cameras, both human operated and robotic, collecting about 500 gigabytes of audio/video per hour—roughly a terabyte (TB) per show. To handle their data storage needs, U2 used several products from EMC Corporation, the first time the company had a musical client. To archive uncompressed footage and access it on-demand during the shows' production, the tour staff used an EMC VNXe3200 portable flash storage unit worth about US$25,000. It was configured with 22.9 TB of storage but was expandable up to 450 TB. After each show, tour staff used an EMC Data Domain 2500 system to back up footage. With storage up to 6.6 petabytes and an hourly throughput of 13.4 TB, the Data Domain system could complete a nightly backup before the crew disassembled the stage. On previous tours, U2 relied on USB flash drives for storage. Video imagery was loaded onto the set's video screens with two d3 Technologies d3 4×4 media servers. Due to the need to load video on the fly, all storage was locally networked, as a cloud storage configuration would have increased latency. EMC's solution satisfied certain requirements dictated by the band, such as: mobility through a flight case form factor; expandable storage; and the capability to handle the large data loads from many cameras.
