A database server needs both high write performance and redundancy, and the budget allows four identical disks. Which RAID level fits, and what capacity results?
Un serveur de base de données a besoin à la fois de bonnes performances en écriture et de redondance, et le budget permet quatre disques identiques. Quel niveau de RAID convient, et quelle capacité obtient-on ?
Answers
ARAID 0, giving the capacity of all four disks and full redundancyLe RAID 0, qui donne la capacité des quatre disques et une redondance complète
BRAID 5, giving the capacity of one diskLe RAID 5, qui donne la capacité d'un seul disque
CRAID 1 across all four disks, giving four times the capacityLe RAID 1 sur les quatre disques, qui donne quatre fois la capacité
DRAID 10: two mirrored pairs striped, giving half the total capacityLe RAID 10 : deux paires en miroir agrégées, qui donnent la moitié de la capacité totale
