Le matériel
Je voulais un serveur petit, silencieux et à très faible consommation électrique.
J'ai choisi un OLIMEX (clone de RASPBERRY) qui apporte les avantages suivants :
- Avoir un vrai port SATA
- Avoir une mémoire interne EMMC pour stocker le système
- Permettre le SSH via USB
J'y a ajouté un disque SSD de 128 Giga, et j'ai un serveur qui consomme moins de 3 Watts avec des performances largement suffisantes pour répondre à mon besoin (pas de graphique ni de calculs lourds)
