A growing amount of digital material from CCTV, crime photos and digital recording has led Humberside Police to install more capacity on their storage area network (San).
Roy Macdona, computer development manager of Humberside Police, said, "Ever since we moved over to San technology we are having exponential increases in demands for storage."
The increases are driven by the growth of digital media, with officers at the scenes of crimes using digital cameras, more CCTV being used, and officers wearing headcams. The force's former storage area network was not expandable enough for future requirements.
Macdona said the force has bought more capacity from Dell, meaning storage of data can be centralised - so it can be backed up and recovered a lot easier.
A lot of police data, such as evidence in a criminal case, needs to be kept for a lifetime or more in case of appeals. The force also relies heavily on e-mails, which also often need to be stored.
While they had not been losing data, Macdona said they were getting to a stage where space was starting to run out. The new addition to the San will keep the force going for four to five years, after which it will review the technology then available.
Macdona, who lost a computer suite in the June floods, moved his department into new premises a couple of weeks ago. He is also virtualising the network, with plans to run 35 servers on three boxes, plus another two boxes for resilience and backup.
He said, "This is keeping power and cooling costs down."
