Flavor Specifications

In the OpenStack context the term “flavor” refers to a hardware profile that can be used for a virtual machine. In Optimist we have set up various standard hardware profiles (flavors). These have different limits, which are listed below for all available flavors.

Migrating between Flavor Types

To change the flavors of existing instances, the OpenStack “Resize Instance” Option can be used either via the Dashboard or the CLI. This will result in a reboot of the Instance but the content of the instance will be preserved.

This does not apply to l1 (localstorage) flavors For more information please see Storage → Localstorage

Deprecated Flavor Types

The following Flavor Types are currently considered deprecated and the removal of these flavor families is planned for the near future. We will regularly check if these flavors are still in use, if not, we will set them to private in order to to avoid new instances being created with them.

• m1-Family (Deprecated)
• e1-Family (e = equal) (Deprecated)
• r1-Family (r = ram) (Deprecated)
• Memory Flavors (Deprecated)
• Windows Flavors (Deprecated)
