c4.large.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:

CPU

RAM

8.0 GB

100GB Ultra-High I/O
