Openstack Flavors
This page covers flavors in OpenStack and describes the pre-defined ones found in this cloud.
To re-clarify what flavors are: flavors encapsule a pre-defined set of compute resources like
VCPUs, RAM and other settings to apply to an instance upon creation.
Flavor types
At the moment we differentiate between two flavor types which are identified by their prefix
of either m1 or c1. The m1 type flavors are based on the generic flavor type of AWS and are
used for general purpose instances that do not require a lot of compute power. The c1 type flavors
are used for instances that expect more CPU bound tasks. Therefore, they double the provided VCPUs
over their m1 counterparts.
Note
You will also see flavors with an exclamation mark next to it. These are exceeding your current quota and can therefore not be used for instance creation.
Currently provided flavors
The table below shows the currently available flavors. These are subject to change as new use cases arise.
| Name | VCPUS | RAM | Total Disk | Root Disk |
|---|---|---|---|---|
| m1.nano | 1 | 512 MB | 10 GB | 10 GB |
| m1.micro | 1 | 1 GB | 10 GB | 10 GB |
| m1.small | 1 | 2 GB | 10 GB | 10 GB |
| m1.medium | 2 | 4 GB | 10 GB | 10 GB |
| m1.large | 2 | 8 GB | 10 GB | 10 GB |
| c1.large | 4 | 8 GB | 10 GB | 10 GB |
| c1.xlarge | 8 | 16 GB | 10 GB | 10 GB |
| m1.xlarge | 4 | 16 GB | 10 GB | 10 GB |
| m1.2xlarge | 8 | 32 GB | 10 GB | 10 GB |
Additional Flavors
If these flavors do not meet your requirements, you can contact the h_da cloud team via the Matrix group or open a ticket. However, please understand that we cannot create flavors for every niche use. Flavors should be as general as possible and remain universally applicable.
