D\u00e9marrer l’installation d’un clusteur de 3 serveurs d\u00e9di\u00e9 chez OVH.
Pour l’exemple j’ai choisi des serveurs d\u00e9di\u00e9s avec 64Go Ram et diff\u00e9rentes configurations de disques dur (SSD 2*480Go, Sata 4*2TO).
La 1\u00e8re \u00e9tape consiste \u00e0 installer les serveurs et le choix du partitionnement \/ syst\u00e8me de fichier ZFS permet ainsi de profiter des fonctions pratiques comme les r\u00e9plications et snap shot …<\/p>\n
