Une nouvelle \u00e9tude de<\/a> TrendForce indique que les applications d’IA d’inf\u00e9rence g\u00e9n\u00e8rent des volumes de donn\u00e9es massifs, mettant \u00e0 rude \u00e9preuve l’\u00e9cosyst\u00e8me mondial du stockage. Les disques durs \u00ab\u00a0Nearline\u00a0\u00bb sont d\u00e9sormais en p\u00e9nurie, avec des d\u00e9lais de livraison allant de quelques semaines \u00e0 plus d’un an. Cette p\u00e9nurie oblige les fournisseurs de services cloud \u00e0 r\u00e9\u00e9valuer leurs architectures de stockage hi\u00e9rarchis\u00e9es.<\/p>\n

Les disques durs \u00ab\u00a0Nearline\u00a0\u00bb sont un type sp\u00e9cial de disque dur con\u00e7u pour le stockage de donn\u00e9es \u00e0 grande \u00e9chelle, comme dans les centres de donn\u00e9es et le stockage dans le cloud. Le terme \u00ab\u00a0nearline\u00a0\u00bb signifie qu’ils ne sont pas aussi rapides qu’un disque \u00ab\u00a0hot\u00a0\u00bb ou \u00ab\u00a0en ligne\u00a0\u00bb utilis\u00e9 pour un acc\u00e8s imm\u00e9diat et fr\u00e9quent, mais qu’ils sont beaucoup plus rapides qu’un stockage \u00ab\u00a0hors ligne\u00a0\u00bb comme une bande magn\u00e9tique. Les lecteurs Nearline sont optimis\u00e9s pour offrir un \u00e9quilibre entre une capacit\u00e9 \u00e9lev\u00e9e, une bonne fiabilit\u00e9 et un bon rapport co\u00fbt-efficacit\u00e9. Ils sont indispensables pour des applications telles que les sauvegardes de donn\u00e9es, le stockage d’archives et le stockage de fichiers volumineux qui n’ont pas besoin d’\u00eatre accessibles instantan\u00e9ment, mais qui doivent tout de m\u00eame \u00eatre facilement disponibles.<\/p>\n

La pression de l’IA sur le stockage des donn\u00e9es<\/h2>\n

Traditionnellement, les donn\u00e9es froides (par exemple, les sauvegardes et les archives) sont stock\u00e9es sur des disques durs en raison de leur faible co\u00fbt. Mais avec le resserrement de l’offre, les FSC envisagent d’utiliser des disques SSD comme alternatives, note TrendForce. Alors que les disques SSD sont d\u00e9j\u00e0 utilis\u00e9s pour les donn\u00e9es \u00ab\u00a0chaudes\u00a0\u00bb et \u00ab\u00a0ti\u00e8des\u00a0\u00bb, la p\u00e9nurie conduit certains FSC \u00e0 envisager de les d\u00e9ployer pour les donn\u00e9es \u00ab\u00a0froides\u00a0\u00bb, malgr\u00e9 des co\u00fbts plus \u00e9lev\u00e9s.<\/p>\n

Selon TrendForce<\/a>, les disques SSD<\/a> Quad-Level Cell (QLC) se pr\u00e9sentent comme des substituts potentiels. Ils offrent non seulement des performances sup\u00e9rieures et une consommation d’\u00e9nergie inf\u00e9rieure d’environ 30 % \u00e0 celle des disques durs, mais aussi une plus grande densit\u00e9. TrendForce pr\u00e9voit que les livraisons de disques SSD QLC de grande capacit\u00e9 pourraient conna\u00eetre une croissance exponentielle en 2026.<\/p>\n

Cependant, la transition n’est pas simple. \u00ab\u00a0Si les CSP pr\u00e9voient d’utiliser des disques SSD QLC pour le stockage de donn\u00e9es froides, ils devront prendre en compte les ajustements des algorithmes de gestion des donn\u00e9es, la compatibilit\u00e9 entre les piles logicielles et les calculs pr\u00e9cis du co\u00fbt total de possession\u00a0\u00bb, pr\u00e9vient<\/a> TrendForce.<\/p>\n

L’IA conduit \u00e0 un changement critique<\/h2>\n

Pour les lecteurs d’ECInews, ce d\u00e9veloppement met en \u00e9vidence un changement critique dans l’infrastructure des donn\u00e9es provoqu\u00e9 par la croissance de l’IA. Elle met en \u00e9vidence les opportunit\u00e9s \u00e9mergentes pour les fournisseurs de stockage et souligne les d\u00e9fis auxquels sont confront\u00e9s les CSP pour r\u00e9pondre \u00e0 la demande.<\/p>\n","protected":false},"excerpt":{"rendered":"
