Tout d'abord, il s'agit de la fonction technique Device Transmit Emphasis pour Gen 3 PHY. Elle permet de se concentrer sur le dispositif \u00e9metteur, mettant ainsi SATA au m\u00eame niveau que d'autres solutions d'entr\u00e9e-sortie lors de la mesure de leurs caract\u00e9ristiques. Cette fonction devrait aider lors des tests et de l'int\u00e9gration des interfaces de nouveaux appareils.<\/p>\n<p>Deuxi\u00e8mement, les sp\u00e9cifications SATA ont introduit la fonction de d\u00e9finition d'ordre des commandes NCQ ou Defined Ordered NCQ Commands. Cela permet \u00e0 l'h\u00f4te de sp\u00e9cifier les relations entre les commandes dans la file d'attente et \u00e9tablit l'ordre dans lequel ces commandes sont trait\u00e9es.<\/p>\n<p>La troisi\u00e8me nouvelle extension de la r\u00e9vision SATA 3.5 est la fonction de limitation de dur\u00e9e des commandes Command Duration Limit Features. Celle-ci vise \u00e0 r\u00e9duire les latences en permettant \u00e0 l'h\u00f4te de d\u00e9finir des cat\u00e9gories de qualit\u00e9 de service gr\u00e2ce \u00e0 un contr\u00f4le plus d\u00e9taill\u00e9 des propri\u00e9t\u00e9s des commandes. De plus, cette fonction aide \u00e0 aligner SATA sur les exigences de \u00ab Fast Fail \u00bb, \u00e9tablies par le projet Open Compute (OCP) et sp\u00e9cifi\u00e9es dans la norme du Comit\u00e9 Technique INCITS T13. Par cons\u00e9quent, cette nouvelle r\u00e9vision de SATA int\u00e8gre toutes les derni\u00e8res mises \u00e0 jour de la norme T13.<\/p>\n<p><center><\/center><\/p>\n<p>Enfin, les sp\u00e9cifications SATA R\u00e9vision 3.5 ont inclus des corrections et des clarifications des sp\u00e9cifications SATA 3.4.<\/p>\n<p>On s'attend \u00e0 ce que l'optimisation du traitement des commandes et la correction des erreurs dans la nouvelle version SATA Revision 3.5 contribuent \u00e0 r\u00e9duire le nombre de cas de \u00ab bouchons \u00bb lors de la transmission intensive de donn\u00e9es via l'interface SATA, ce qui ne peut que \u00eatre bienvenu.<\/p>\n<p><strong>Source :<\/strong><\/p>\n<ul class=\"related\">\n<li><noindex><a rel=\"nofollow noopener noreferrer\" href=\"http:\/\/www.cdrlabs.com\/\"
