J'essaie de faire fonctionner le NIC bonding avec balance-rr pour que trois ports NIC soient combinés, de sorte qu'au lieu d'obtenir 1 Gbps, nous obtenions 3 Gbps. Nous faisons cela sur deux serveurs connectés au même commutateur. Cependant, nous n'obtenons que la vitesse d'un seul lien physique.
Nous utilisons un Dell PowerConnect 5324, version SW 2.0.1.3, version Boot 1.0.2.02, version HW 00.00.02. Les deux serveurs sont sous CentOS 5.9 (Final) et utilisent l'hyperviseur OnApp (CloudBoot).
Le serveur 1 utilise les ports g5-g7 dans le canal de port 1. Le serveur 2 utilise les ports g9-g11 dans le canal de port 2.

Savez-vous si le PowerConnect supporte le teaming balance-rr ? De nos jours, de nombreux commutateurs ne prennent plus en charge cette fonction et s'appuient davantage sur la norme LACP 802.3ad pour lier les cartes réseau.
