# Flavors
OpenStack flavor entity defines compute virtual server parameters such as:
* virtual server specifications
* vCPU count
* memory amount
* storage size (both distributed, ephemeral)
* defines QoS (IOPs, network bandwith, ...)
* grants access to additional resources (hardware cards for instance GPU)
* defines set of compute hypervisors where can be virtual server scheduled
## Flavor types
We differentiate following flavor types:
* Standard flavors `standard.*` focused on high availability, support for (live) VM migration but lower performance.
* HPC flavors `hpc.*` are focused on performance (NUMA, local ephemeral disks), access to premium HW (GPUs).
## Most frequently used flavors
| Flavor name | CPU | RAM (GB) | HPC | SSD | Disc throughput (MB/s) | IOPS | Average throughput (MB/s) | GPU |
|-------------------------------------------|------|----------|------|------|------------------------|------------|----------------------------|-----|
| elixir.hda1 | 30 | 724 | Yes | No | Unlimited | Unlimited | Unlimited | No |
