Example of disk space requirements calculations

Assumptions:

  • In average, a business user makes 10 calls per day with a duration 5 minutes. This results into 1,000 minutes per user per month (assuming 20 working days).
  • File format is MP3 stereo 32kbps, i.e. 0.24MB/minute

Approximate disk space requirements (see assumptions):

Total users 30 days storage 1 year storage 3 year storage 7 year storage
50 12 GB 144 GB 432 GB 1,000 GB
100 24 GB 288 GB 864 GB 2,000 GB
200 48 GB 576 GB 1,728 GB 4,000 GB
500 120 GB 1,440 GB 4,320 GB 10,000 GB
1,000 240 GB 2,880 GB 8,640 GB 20,000 GB
2,000 480 GB 5,760 GB 17,280 GB 40,000 GB

Screen recording storage requirements

Screen recording compression is configurable under Administration -> Screen Recording -> Screen Recording Settings.

A default bitrate is 256kbps, which is the best balance between video quality and file size.

Bitrate Size per minute Hours per TB
256kbps 1.92 MB/minute 9,102 hours/TB
