Mukuvaka kwe x86 mapuratifomu, maitiro maviri akabuda anopindirana. Zvinoenderana neimwe vhezheni, isu tinofanirwa kuenda kune kubatanidza komputa uye kutonga zviwanikwa mune imwe chip. Yechipiri nzira inosimudzira kugoverwa kwemabasa: iyo processor yakashongedzerwa nebhazi rinoshanda kwazvo rinoumba peripheral scalable ecosystem. Inoumba hwaro hweIntel C620 system logic topology yemapuratifomu epamusoro.
Musiyano wakakosha kubva kune yakapfuura Intel C610 chipset ndiko kuwedzera kweiyo nzira yekutaurirana pakati pe processor uye peripherals inosanganisirwa muPCH chip kuburikidza nekushandiswa kwePCIe link pamwe neyakajairwa DMI bhazi.
Ngatitarisei zvakanyanya magadzirirwo eIntel Lewisburg maodzanyemba zambuko: ndedzipi nzira dzekushanduka-shanduka uye dzechimurenga dzakawedzera masimba ayo mukutaurirana nema processor?
Evolutionary shanduko muCPU-PCH kutaurirana
Sechikamu chenzira yekushanduka-shanduka, nzira huru yekukurukurirana pakati peCPU nezambuko rezasi, rinova bhazi reDMI (Direct Media Interface), rakawana rutsigiro rwePCIe x4 Gen3 modhi nekuita kwe8.0 GT/S. Pakutanga, muIntel C610 PCH, kutaurirana pakati pe processor uye system logic yakaitwa muPCIe x4 Gen 2 modhi pa5.0 GT/S bandwidth.
Kuenzanisa kweiyo system logic kushanda kweIntel C610 uye C620
Ziva kuti iyi subsystem yakanyanya kuchengetedza kupfuura yakavakirwa-mukati PCIe ports ye processor, inowanzo shandiswa kubatanidza maGPU neNVMe madhiraivha, uko PCIe 3.0 yakashandiswa kwenguva yakareba uye shanduko kuenda kuPCI Express Gen4 yakarongwa.
Shanduko dzekuchinja muCPU-PCH kutaurirana
Shanduko dzekuchinja dzinosanganisira kuwedzera kwePCIe CPU-PCH nzira dzekutaurirana, dzinodaidzwa kuti Kuwedzera Uplinks. Panyama, aya maviri PCI Express madoko anoshanda muPCIe x8 Gen3 uye PCIe x16 Gen3 modhi, ese 8.0 GT/S.
Pakudyidzana pakati peCPU neIntel C620 PCH, mabhazi matatu anoshandiswa: DMI uye maviri PCI Express ports.
Nei zvaive zvakafanira kudzokorora yaivepo yekutaurirana topology neIntel C620? Chekutanga, kusvika ku4x 10GbE network controllers ine RDMA mashandiro anogona kubatanidzwa muPCH. Kechipiri, chizvarwa chitsva uye chinokurumidza cheIntel QuickAssist Technology (QAT) coprocessors, iyo inopa tsigiro yehardware yekumanikidza uye encryption, ine basa re encrypting network traffic uye kuchinjana neiyo yekuchengetedza subsystem. Uye pakupedzisira, "injini yekuvandudza" - , iyo inongowanikwa kune maOEMs.
Scalability uye kuchinjika
Chinhu chakakosha kugona kusarudza kwete chete PCH yekubatanidza topology, asiwo zvinokosheswa zvemukati zviwanikwa zvechip mukuwana nzira dzekukurumidzira dzekukurukurirana nepakati processor (processors). Uye zvakare, mune yakakosha EPO (EndPoint Chete Mode), iyo PCH yekubatanidza inoitwa muchimiro cheyakajairwa PCI Express mudziyo une gumi GbE zviwanikwa uye Intel QAT. Panguva imwecheteyo, iyo yekare DMI interface, pamwe nenhamba yeNhaka subsystems, inoratidzwa mutema mudhiyagiramu, yakaremara.
Kuvaka kwemukati kweIntel C620 PCH chip
Mune dzidziso, izvi zvinoita kuti zvikwanise kushandisa inopfuura imwe Intel C620 PCH chip muhurongwa, kuyera 10 GbE uye Intel QAT mashandiro kuti asangane nekuita zvinodiwa. Panguva imwecheteyo, Legacy mabasa anongodiwa mukopi imwe chete anogona kugoneswa chete pane imwe yakaiswa PCH chips.
Saka, iyo yekupedzisira kutaura mukugadzira ichave yemugadziri wepuratifomu, ichiita pahwaro hwezvose zviri zviviri tekinoroji uye zvekushambadzira zvinhu zvinoenderana nekumisikidzwa kwechimwe nechimwe chigadzirwa.
