Nova flavors

In NERC OpenStack, flavors define the compute, memory, and storage capacity of nova computing instances. In other words, a flavor is an available hardware configuration for a server.

Currently, our setup supports the following flavors

Each flavor includes enforced quotas for disk limits through maximum disk read, write, and total bytes per second and disk limits through maximum disk read, write, and total I/O operations per second. They also include enforced network bandwidth limits through inbound and outbound average.

So, while launching a VM choose the flavor for your instance that fits your requirements and use-cases.
