Schimb\u0103ri evolu\u021bionare \u00een comunica\u021bia CPU-PCH<\/h2>\n

\n\u00cen cadrul abord\u0103rii evolu\u021bionare, canalul principal de comunicare CPU cu podul sudic, care este bus-ul DMI (Direct Media Interface), a primit suport pentru modul PCIe x4 Gen3 cu o performan\u021b\u0103 de 8.0 GT\/S. Anterior, \u00een Intel C610 PCH, comunica\u021bia \u00eentre procesor \u0219i logica sistemului se realiza \u00een modul PCIe x4 Gen 2 cu o l\u0103\u021bime de band\u0103 de 5.0 GT\/S.<\/p>\n

Observ\u0103m c\u0103 acest subsistem este semnificativ mai conservator dec\u00e2t porturile PCIe integrate ale procesorului, de obicei utilizate pentru conectarea GPU-urilor \u0219i a unit\u0103\u021bilor de stocare NVMe, unde PCIe 3.0 este deja utilizat pe scar\u0103 larg\u0103, iar tranzi\u021bia c\u0103tre PCI Express Gen4 este preconizat\u0103.<\/p>\n

Schimb\u0103ri revolu\u021bionare \u00een comunica\u021bia CPU-PCH<\/h2>\n

\nPrintre schimb\u0103rile revolu\u021bionare se num\u0103r\u0103 ad\u0103ugarea unor noi canale PCIe pentru comunica\u021bia CPU-PCH, numite Additional Uplinks.

\nPentru interac\u021biunea CPU \u0219i Intel C620 PCH sunt folosite 3 bus-uri: DMI \u0219i dou\u0103 porturi PCI Express<\/em><\/p>\n

De ce a fost necesar\u0103 revizuirea topologiei existente a comunica\u021biilor cu Intel C620? \u00cen primul r\u00e2nd, \u00een cadrul PCH pot fi integrate p\u00e2n\u0103 la 4 controlere de re\u021bea 10GbE cu func\u021bionalitate RDMA. \u00cen al doilea r\u00e2nd, criptarea traficului de re\u021bea \u0219i a transferului de date cu subsistemul de stocare este responsabilizat\u0103 de o nou\u0103 genera\u021bie mai rapid\u0103 de coprocesoare Intel QuickAssist Technology (QAT), care ofer\u0103 suport hardware pentru comprimare \u0219i criptare. \u0218i, \u00een cele din urm\u0103, \u201emotorul inova\u021biei\u201d \u2014 Innovation Engine<\/a><\/noindex>, care va fi disponibil doar pentru produc\u0103torii OEM.<\/p>\n

Scalabilitate \u0219i flexibilitate<\/h2>\n

\nO caracteristic\u0103 important\u0103 este posibilitatea de a alege op\u021bional nu doar topologia de conectare a PCH-ului, ci \u0219i priorit\u0103\u021bile resurselor interne ale cipului \u00een accesarea canalelor de comunica\u021bie rapide cu procesorul (procesorii). \u00cen plus, \u00een modul special EPO (EndPoint Only Mode), conectarea PCH-ului se face \u00een statusul unui dispozitiv PCI Express obi\u0219nuit, care con\u021bine resurse de 10 GbE \u0219i Intel QAT. \u00cen acest caz, interfa\u021ba clasic\u0103 DMI, precum \u0219i o serie de subsisteme Legacy, ar\u0103tate pe diagram\u0103 cu negru, sunt dezactivate.<\/p>\n

Teoretic, aceasta permite utilizarea \u00een sistem a mai mult de un cip Intel C620 PCH, scal\u00e2nd func\u021bionalitatea 10 GbE \u0219i Intel QAT \u00een conformitate cu cerin\u021bele de performan\u021b\u0103. \u00cen acest fel, func\u021biile Legacy, necesare doar \u00eentr-un singur exemplar, pot fi activate doar pe unul dintre cipurile PCH instalate.<\/p>\n
