Les disques SSD NVMe™ performants facilitent les charges de travail des entreprises

L'adoption de NVMe™ dans le centre de données continue de croître car les applications et les charges de travail modernes exigent davantage de performances. Les SSD NVMe haute performance sont conçus pour le stockage primaire des serveurs HPC et le stockage primaire dans les baies de stockage externes.

Détails sur le produit

Les disques SSD NVMe™ performants facilitent les charges de travail des entreprises
Les disques SSD NVMe haute performance ciblent les charges de travail de calcul en nuage et d'entreprise qui nécessitent une faible latence vers les données et une haute disponibilité des données. Ces applications comprennent l'analyse des données en temps réel, l'informatique en nuage, les bases de données OLTP/OLAP, l'intelligence artificielle (IA), l'apprentissage automatique, la reconnaissance des formes et la virtualisation. Le disque Ultrastar DC SN840 est la troisième génération de SSD NVMe de Western Digital pour les centres de données avec PCIe Gen 3.1 (double port), NVMe 1.3, fournissant jusqu'à 3 470/3 300 Mo/s en lecture/écriture séquentielle et jusqu'à 503 000 IOPS en lecture/écriture aléatoire mixte 70/30.

Leadership en matière de double port
Le disque Ultrastar DC SN840 étend le leadership de Western Digital en matière d'architecture à double port en intégrant verticalement des contrôleurs flash éprouvés. La haute disponibilité à double port prend en charge deux chemins redondants vers le SSD et est essentielle pour garantir l'accès aux données en cas de défaillance du chemin de données.
