Nouvelle prometteuse pour le Cloud hyperscale et les adeptes du Leaf & Spine : le nouveau commutateur Tomahawk \u00ae<\/strong><\/a> du constructeur am\u00e9ricain affiche une (colossale) puissance de traitement r\u00e9seau de\u2026 25,6 Tbits\/s. Cela repr\u00e9sente 256 ports 100 GbE pris en charge par un syst\u00e8me \u00e0 puce unique. La strat\u00e9gie habituelle de conception du g\u00e9ant industriel s’applique donc. Toutefois, il est possible de r\u00e9organiser autrement la bande passante disponible : 64 ports 400 GbE, par exemple.<\/p>\n

De quoi g\u00e9n\u00e9rer un choc de performance des architectures r\u00e9seau des Datacenters, avec de nombreux b\u00e9n\u00e9fices annexes. En effet, le StrataXGS \u00ae Tomahawk \u00ae 4 est particuli\u00e8rement repr\u00e9sentatif d\u2019une tendance globale \u00e0 la simplification drastique des architectures r\u00e9seaux physiques par consolidation\/suppression des agr\u00e9gats. Avec, \u00e0 la cl\u00e9, de substantielles \u00e9conomies d\u2019\u00e9nergie et une exploitation facilit\u00e9e. Autre enjeu crucial adress\u00e9 : la r\u00e9duction de la latence r\u00e9seau. En cause ici, l’am\u00e9lioration des performances du stockage et l\u2019hyper-distribution de la puissance de calcul. Ces \u00e9volutions ne n\u00e9cessitent pas seulement l’\u00e9limination des congestions, mais aussi la simplification des cha\u00eenes de liaison.<\/p>\n","protected":false},"excerpt":{"rendered":"
