Comme annonc\u00e9 \u00e0 l'\u00e9poque, les livraisons des barrettes Optane ont commenc\u00e9 au deuxi\u00e8me trimestre 2019, et \u00e0 ce moment-l\u00e0, nous avions accumul\u00e9 suffisamment d'informations qui faisaient d\u00e9faut lors de l'annonce. Alors, sous le cut, les sp\u00e9cifications techniques et les mod\u00e8les d'utilisation <noindex><a rel=\"nofollow\" href=\"https:\/\/www.intel.com\/content\/www\/us\/en\/products\/memory-storage\/optane-dc-persistent-memory.html\">Optane DC Persistent Memory<\/a><\/noindex>, ainsi que diff\u00e9rentes infographies.<br \/>\n<noindex><a rel=\"nofollow\" name=\"habracut\"><\/a><\/noindex><br \/>\nAinsi, comme indiqu\u00e9, les modules Optane DC Persistent Memory (Optane DC PM) s'installent dans des slots DIMM DDR4 standard, mais leur utilisation n\u00e9cessite le support du contr\u00f4leur de m\u00e9moire, donc ce type de m\u00e9moire ne peut \u00eatre utilis\u00e9 pour le moment qu'avec les processeurs Intel Xeon Scalable Gold ou Platinum de deuxi\u00e8me g\u00e9n\u00e9ration. Un module Optane DC PM peut \u00eatre install\u00e9 par canal m\u00e9moire, soit jusqu'\u00e0 6 modules par socket, ce qui fait un total de 3 To ou 24 To sur un serveur \u00e0 8 sockets.<\/p>\n<p><img decoding=\"async\" alt=\"Intel Optane DC Persistent Memory, un an apr\u00e8s\" src=\"\/wp-content\/uploads\/2019\/06\/5ab2c4ec05b77d285abeb177da82cc6b.png\" style=\"display:block;margin: 0 auto;\" \/><br \/>\n<br \/>\nOptane DC PM est disponible en modules de 3 tailles : 128, 256 et 512 Go \u2014 bien plus que les barrettes DDR DIMM disponibles actuellement. Il existe deux principales fa\u00e7ons de l'utiliser et d'interagir avec la m\u00e9moire traditionnelle.<\/p>\n<ul>\n<li><b>Mode m\u00e9moire<\/b> \u2014 ne n\u00e9cessite aucune modification des applications. Dans ce mode, Optane DC PM est utilis\u00e9 comme m\u00e9moire vive adressable principale, et le volume existant de DRAM traditionnelle comme cache pour Optane. Le mode m\u00e9moire permet de fournir aux applications un volume consid\u00e9rable de RAM \u00e0 un prix sensiblement inf\u00e9rieur, ce qui peut \u00eatre important lors de l'h\u00e9bergement de machines virtuelles, de grandes bases de donn\u00e9es, etc. Il convient de noter que dans ce mode, la m\u00e9moire persistante Optane DC est d\u00e9pendante de l'\u00e9nergie, car les donn\u00e9es qu'elle contient sont chiffr\u00e9es avec une cl\u00e9 qui est perdue lors du red\u00e9marrage.<\/li>\n<li><b>Mode d'acc\u00e8s direct<\/b> \u2014 les applications et les logiciels peuvent acc\u00e9der directement \u00e0 Optane DC PM, simplifiant ainsi la cha\u00eene d'appels. De plus, dans ce mode, il est possible d'utiliser les API existantes de stockage, ce qui permet de traiter la m\u00e9moire comme un SSD et, en particulier, de d\u00e9marrer \u00e0 partir de celle-ci. Le syst\u00e8me voit Optane DC PM et DRAM comme deux pools de m\u00e9moire ind\u00e9pendants. Votre avantage est un stockage de grande capacit\u00e9, non volatile, rapide et fiable pour les applications sensibles aux \u00e9changes de donn\u00e9es et aux besoins syst\u00e8mes. <\/li>\n<\/ul>\n<p>\nIl est \u00e9galement possible d'avoir une solution interm\u00e9diaire : une partie des modules Optane DC PM est utilis\u00e9e en mode m\u00e9moire, tandis qu'une autre partie fonctionne en mode d'acc\u00e8s direct. La diapositive suivante montre les avantages de l'utilisation de la m\u00e9moire persistante Intel Optane DC pour l'h\u00e9bergement de machines virtuelles.<\/p>\n<p><img decoding=\"async\" alt=\"Intel Optane DC Persistent Memory, un an apr\u00e8s\" src=\"\/wp-content\/uploads\/2019\/06\/ce5bbac059568b89df753f8c07318e67.png\" style=\"display:block;margin: 0 auto;\" \/><br \/>\n<br \/>\nVoici maintenant les sp\u00e9cifications techniques des modules de m\u00e9moire.<\/p>\n<p>Capacit\u00e9<br \/>\n 128 GiB<br \/>\n 256 GiB<br \/>\n 512 GiB<\/p>\n<p>Mod\u00e8le<br \/>\n NMA1XXD128GPS<br \/>\n NMA1XXD256GPS<br \/>\n NMA1XXD512GPS<\/p>\n<p>Garantie<br \/>\n 5 ans<\/p>\n<p>AFR<br \/>\n \u2264 0.44<\/p>\n<p>Endurance 100% \u00e9criture 15W 256B<br \/>\n 292 PBW<br \/>\n 363 PBW<br \/>\n 300 PBW<\/p>\n<p>Endurance 100% \u00e9criture 15W 64B<br \/>\n 91 PBW<br \/>\n 91 PBW<br \/>\n 75 PBW<\/p>\n<p>Vitesse 100% lecture 15W 256B<br \/>\n 6.8 GB\/s<br \/>\n 6.8 GB\/s<br \/>\n 5.3 GB\/s<\/p>\n<p>Vitesse 100% \u00e9criture 15W 256B<br \/>\n 1.85 GB\/s<br \/>\n 2.3 GB\/s<br \/>\n 1.89 GB\/s<\/p>\n<p>Vitesse 100% lecture 15W 64B<br \/>\n 1.7 GB\/s<br \/>\n 1.75 GB\/s<br \/>\n 1.4 GB\/s<\/p>\n<p>Vitesse 100% \u00e9criture 15W 64B<br \/>\n 0.45 GB\/s<br \/>\n 0.58 GB\/s<br \/>\n 0.47 GB\/s<\/p>\n<p>Fr\u00e9quence DDR<br \/>\n 2666, 2400, 2133, 1866 MT\/s<\/p>\n<p>Max.

Les 512 Go ne sont pas encore disponibles, probablement en raison d'une sortie ult\u00e9rieure. Ainsi, le co\u00fbt unitaire commence \u00e0 partir de $7 par Go, ce qui est comparable au prix d'un gigaoctet de m\u00e9moire serveur RDIMM.<br \/>\n<br \/>Source : <a content=\"nofollow\"
