Pour r\u00e9pondre \u00e0 cette demande croissante,\u00a0Texas Instruments (TI)\u00a0collabore avec\u00a0NVIDIA\u00a0sur une nouvelle g\u00e9n\u00e9ration de technologies de gestion de l\u2019\u00e9nergie et de d\u00e9tection, con\u00e7ues pour les syst\u00e8mes de distribution \u00e0\u00a0courant continu haute tension (CCHT) de 800 V.<\/h3>\n

Une r\u00e9ponse aux d\u00e9fis \u00e9nerg\u00e9tiques de l\u2019IA<\/span><\/h4>\n

Les centres de donn\u00e9es modernes, en particulier ceux d\u00e9di\u00e9s \u00e0 l\u2019IA, voient leur consommation \u00e9nerg\u00e9tique par rack passer de\u00a0100 kW aujourd\u2019hui \u00e0 plus de 1 MW\u00a0dans un avenir proche. Une telle mont\u00e9e en puissance rend les architectures actuelles, notamment les syst\u00e8mes 48 V, obsol\u00e8tes. \u00c0 titre d\u2019exemple, alimenter un rack de 1 MW en 48 V n\u00e9cessiterait pr\u00e8s de\u00a0200 kg de cuivre, un poids et un encombrement difficilement soutenables \u00e0 grande \u00e9chelle.<\/span><\/p>\n

C\u2019est dans ce contexte que l\u2019architecture\u00a0800 V CCHT\u00a0s\u2019impose comme une solution d\u2019avenir. Elle permet une\u00a0densit\u00e9 de puissance accrue, une\u00a0efficacit\u00e9 de conversion optimis\u00e9e, et une\u00a0r\u00e9duction significative de la taille et du poids\u00a0des syst\u00e8mes d\u2019alimentation. Cette approche ouvre la voie \u00e0 des centres de donn\u00e9es plus\u00a0scalables, plus\u00a0fiables, et mieux adapt\u00e9s aux exigences de l\u2019IA.<\/span><\/p>\n

Une collaboration strat\u00e9gique entre TI et NVIDIA<\/span><\/h4>\n

Selon\u00a0Jeffrey Morroni, directeur R&D en gestion de l\u2019\u00e9nergie chez TI, \u00ab un changement de paradigme est en cours \u00bb. Il souligne que les infrastructures 48 V, autrefois consid\u00e9r\u00e9es comme le prochain d\u00e9fi, sont d\u00e9sormais d\u00e9pass\u00e9es par les besoins colossaux de l\u2019IA. Gr\u00e2ce \u00e0 l\u2019expertise de TI en conversion d\u2019\u00e9nergie et \u00e0 la ma\u00eetrise de NVIDIA en mati\u00e8re d\u2019IA, cette nouvelle architecture 800 V devient une r\u00e9alit\u00e9.<\/span><\/p>\n

Gabriele Gorla, responsable de l\u2019ing\u00e9nierie des syst\u00e8mes chez NVIDIA, ajoute que les\u00a0syst\u00e8mes d\u2019alimentation \u00e0 semi-conducteurs\u00a0sont essentiels pour faire \u00e9merger des infrastructures IA haute performance. L\u2019objectif : alimenter efficacement la prochaine g\u00e9n\u00e9ration de\u00a0centres de donn\u00e9es IA \u00e0 grande \u00e9chelle.<\/span><\/p>\n
