Open Telekom Cloud 2020 - FIO Bandwidth


Beside IOPS, we also used thoughput/bandwidth to qualify storage performance and like IOPS we used FIO to collect this metric. For this scenario, the following configuration has been used:

  • Block size: Small size of 1MB
  • Access: Read and write not mixed
  • Mode: Sequential avoiding necessary computation
  • No file system: Only infrastructure performance are relevant
  • Miscellaneous: We avoid most as possible buffers and cache
