# Optimiser les performances d’Amazon FSx pour Lustre sur les nœuds (EFA)
<a name="fsx-csi-tuning-efa"></a>

Cette rubrique décrit comment configurer le réglage Elastic Fabric Adapter (EFA) avec Amazon EKS et Amazon FSx pour Lustre.

**Note**  
Pour plus d’informations sur la création et le déploiement du pilote CSI FSx pour Lustre, consultez [Déployez le pilote FSx for Lustre](fsx-csi-create.md).
Pour optimiser les nœuds standard sans EFA, voir [Optimisez les performances FSx d'Amazon for Lustre sur les nœuds (non EFA)](fsx-csi-tuning-non-efa.md).

## Étape 1. Créer un cluster EKS
<a name="create-eks-cluster"></a>

Créez un cluster à l’aide du fichier de configuration fourni :

```
# Create cluster using efa-cluster.yaml
eksctl create cluster -f efa-cluster.yaml
```

Exemple `efa-cluster.yaml` :

```
#efa-cluster.yaml

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig

metadata:
  name: csi-fsx
  region: us-east-1
  version: "1.30"

## Étape 2. Créer un groupe de nœuds
<a name="create-node-group"></a>

Créez un groupe de EFA-enabled nœuds :

```
# Create node group using efa-ng.yaml
eksctl create nodegroup -f efa-ng.yaml
```

**Important**  
Ajustez ces valeurs pour votre environnement dans la section`# 5. Mount FSx filesystem`.  

```
FSX_DNS="<your-fsx-filesystem-dns>" # Needs to be adjusted.
MOUNT_NAME="<your-mount-name>" # Needs to be adjusted.
MOUNT_POINT="</your/mount/point>" # Needs to be adjusted.
```

Exemple `efa-ng.yaml` :

```
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig

metadata:
  name: final-efa
  region: us-east-1

managedNodeGroups:

## (Facultatif) Étape 3. Vérifier EFA
<a name="verify-efa-setup"></a>

Accéder au nœud via SSH :

```
# Get instance ID from EKS console or {aws} CLI
ssh -i /path/to/your-key.pem ec2-user@<node-internal-ip>
```

Vérifier EFA :

```
sudo lnetctl net show
```

Consultez les journaux de configuration :

```
sudo cat /var/log/cloud-init-output.log
```

Voici un exemple de sortie attendue pour `lnetctl net show` :

```
net:
    - net type: tcp
      ...
    - net type: efa
      local NI(s):
        - nid: xxx.xxx.xxx.xxx@efa
          status: up
```

## Exemple de déploiement
<a name="example-deployments"></a>

### a. Créer claim.yaml
<a name="_a_create_claim_yaml"></a>

```
#claim.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: fsx-claim-efa
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: ""
  resources:
    requests:
      storage: 4800Gi
  volumeName: fsx-pv
```

Appliquez la réclamation :

```
kubectl apply -f claim.yaml
```

### b. Créer pv.yaml
<a name="_b_create_pv_yaml"></a>

Mettre à jour le :`<replaceable-placeholders>`

```
#pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: fsx-pv
spec:
  capacity:
    storage: 4800Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteMany
  mountOptions:
    - flock
  persistentVolumeReclaimPolicy: Recycle
  csi:
    driver: fsx.csi.aws.com
    volumeHandle: fs-<1234567890abcdef0>
    volumeAttributes:
      dnsname: fs-<1234567890abcdef0>.fsx.us-east-1.amazonaws.com
      mountname: <abcdef01>
```

Appliquez le volume persistant :

```
kubectl apply -f pv.yaml
```

### c. Créer pod.yaml
<a name="_c_create_pod_yaml"></a>

```
#pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: fsx-efa-app
spec:
  containers:
  - name: app
    image: amazonlinux:2
    command: ["/bin/sh"]
    args: ["-c", "while true; do dd if=/dev/urandom bs=100M count=20 > data/test_file; sleep 10; done"]
    resources:
      requests:
        vpc.amazonaws.com/efa: 1
      limits:
        vpc.amazonaws.com/efa: 1
    volumeMounts:
    - name: persistent-storage
      mountPath: /data
  volumes:
  - name: persistent-storage
    persistentVolumeClaim:
      claimName: fsx-claim-efa
```

Appliquez le pod :

```
kubectl apply -f pod.yaml
```

## Commandes de vérification supplémentaires
<a name="verification-commands"></a>

Vérifiez que Pod monte et écrit sur le système de fichiers :

```
kubectl exec -ti fsx-efa-app -- df -h | grep data
# Expected output:
# <192.0.2.0>@tcp:/<abcdef01>  4.5T  1.2G  4.5T   1% /data

kubectl exec -ti fsx-efa-app -- ls /data
# Expected output:
# test_file
```

Connectez-vous au nœud en SSH pour vérifier que le trafic passe par EFA :

```
sudo lnetctl net show -v
```

Le résultat attendu affichera les interfaces EFA avec les statistiques de trafic.
