## General FAQs

### 1. What devices are currently supported?

Currently, **ONLY Atlas A2 series**  (Ascend-cann-kernels-910b) are supported:

- Atlas A2 Training series (Atlas 800T A2, Atlas 900 A2 PoD, Atlas 200T A2 Box16, Atlas 300T A2)
- Atlas 800I A2 Inference series (Atlas 800I A2)

Below series are NOT supported yet:
- Atlas 300I Duo、Atlas 300I Pro (Ascend-cann-kernels-310p) might be supported on 2025.Q2
- Atlas 200I A2 (Ascend-cann-kernels-310b) unplanned yet
- Ascend 910, Ascend 910 Pro B (Ascend-cann-kernels-910) unplanned yet

From a technical view, vllm-ascend support would be possible if the torch-npu is supported. Otherwise, we have to implement it by using custom ops. We are also welcome to join us to improve together.

### 2. How to get our docker containers?

You can get our containers at `Quay.io`, e.g., [<u>vllm-ascend</u>](https://quay.io/repository/ascend/vllm-ascend?tab=tags) and [<u>cann</u>](https://quay.io/repository/ascend/cann?tab=tags).

If you are in China, you can use `daocloud` to accelerate your downloading:

1) Open `daemon.json`:

```bash
vi /etc/docker/daemon.json
```

2) Add `https://docker.m.daocloud.io` to `registry-mirrors`:

```json
{
  "registry-mirrors": [
        "https://docker.m.daocloud.io"
    ]
}
```

3) Restart your docker service:

```bash
sudo systemctl daemon-reload
sudo systemctl restart docker
```

After configuration, you can download our container from `m.daocloud.io/quay.io/ascend/vllm-ascend:v0.7.3rc2`.
