c4.3xlarge.4 by T-Systems Open Telekom Cloud


I/O rate testing are conducted with local and block storages attached to the instance. We use the well-known open-source tool FIO. To express IOPS the following parameters are used:

  • 4K block
  • Random access
  • No filesystem (except for write access with root volume)
  • Avoidance of cache and buffer
Specifications:
