Flavors are declined in several versions offering different levels of performances. The suffix -perf1 or -perf2 behind a flavor means different level of iops and write speed.
Example :
| flavor | max performances |
|---|---|
| a8-ram16-disk20-perf1 | iops: 500. read and writes : 200MB/s |
| a8-ram16-disk20-perf2 | iops: 1000. read and writes : 400MB/s |
Warning
the -perf2 flavors are only available upon request, please contact our support to enable it for your project.
You can see all flavor properties using the command:
openstack flavor list --long
$ openstack flavor list --long

The important fields are
| Field | Description |
|---|---|
| RAM | Memory size in MB |
| Disk | Size of disk in GB. 0 means that the disk is the same size as the image |
| Ephemeral | Size of a second disk. See the ephemeral disks section for more details |
| VCPUs | Number of virtual cores |
GPUs
You can have a dedicated NVidia GPU T4 attached to your VM using flavors prefixed with nvt4
Warning
the nvt4 flavors are only available upon request, please contact our support to enable it for your project.
