OVHcloud Metal Instances - IOPS

Go back to list

Filter:


I/O Per Seconds is one of the most used value to evaluate the performance of a volume, raw SSD, magnetic or Block Storage. The average and maximum IOPS gives a good preview of what will be the speed of a database or any disk-intensive task.

To measure IOPS, we use the well known tool Flexible I/O Tester (FIO) the following configuration:

  • 4KB blocks
  • Random access
  • Read then Write
  • Direct access to device without filesystems
  • libaio engine

Cloud Mercato's assertions

Block storage and Local SSD are of course not directly comparable. The first one is a real Cloud service with its flexibility and ecosystem, when the second is a classical hardware provided to you.

As we can see, the physical device offer the best performance for OVHcloud:

  • 650K IOPS in read
  • 325K IOPS in write
