Hauv kev tsim qauv ntawm x86 platforms, ob qho kev sib txawv tau tshwm sim uas sib ntxiv rau ib leeg. Raws li ib qho version, peb yuav tsum txav mus rau kev sib koom ua ke suav thiab tswj cov peev txheej rau hauv ib lub nti. Qhov thib ob txoj hauv kev txhawb nqa kev faib tawm ntawm lub luag haujlwm: lub processor yog nruab nrog lub tsheb npav ua haujlwm siab uas tsim cov khoom siv hluav taws xob peripheral scalable ecosystem. Nws tsim lub hauv paus ntawm Intel C620 system logic topology rau qib siab platforms.
Qhov tseem ceeb sib txawv los ntawm yav dhau los Intel C610 chipset yog kev nthuav dav ntawm kev sib txuas lus ntawm cov processor thiab cov khoom siv nrog rau hauv PCH nti los ntawm kev siv PCIe txuas nrog rau cov tsoos DMI tsheb npav.
Cia peb saib ze dua ntawm kev tsim kho tshiab ntawm Intel Lewisburg sab qab teb choj: dab tsi hloov pauv thiab hloov pauv txoj hauv kev tau nthuav dav nws lub zog hauv kev sib txuas lus nrog cov txheej txheem?
Kev hloov pauv hloov pauv hauv CPU-PCH kev sib txuas lus
Raws li ib feem ntawm evolutionary mus kom ze, lub ntsiab kev sib txuas lus channel ntawm CPU thiab sab qab teb choj, uas yog lub tsheb npav DMI (Direct Media Interface), tau txais kev txhawb nqa rau PCIe x4 Gen3 hom nrog kev ua tau zoo ntawm 8.0 GT / S. Yav dhau los, hauv Intel C610 PCH, kev sib txuas lus ntawm cov txheej txheem thiab cov txheej txheem logic tau ua hauv PCIe x4 Gen 2 hom ntawm 5.0 GT / S bandwidth.
Kev sib piv ntawm qhov system logic functionality ntawm Intel C610 thiab C620
Nco ntsoov tias lub subsystem no muaj kev saib xyuas ntau dua li cov chaw nres nkoj hauv PCIe ntawm lub processor, feem ntau yog siv los txuas GPUs thiab NVMe drives, qhov twg PCIe 3.0 tau siv los ntev thiab kev hloov mus rau PCI Express Gen4 tau npaj.
Kev hloov pauv hloov hauv CPU-PCH kev sib txuas lus
Kev hloov pauv hloov pauv suav nrog qhov sib ntxiv ntawm PCIe CPU-PCH kev sib txuas lus tshiab, hu ua Additional Uplinks. Lub cev, cov no yog ob lub PCI Express chaw nres nkoj ua haujlwm hauv PCIe x8 Gen3 thiab PCIe x16 Gen3 hom, ob qho tib si 8.0 GT / S.
Rau kev sib cuam tshuam ntawm CPU thiab Intel C620 PCH, 3 tsheb npav siv: DMI thiab ob lub PCI Express ports
Vim li cas thiaj yuav tsum tau kho qhov kev sib txuas lus uas twb muaj lawm nrog Intel C620? Ua ntej, mus txog 4x 10GbE network controllers nrog RDMA functionality tuaj yeem muab tso rau hauv PCH. Qhov thib ob, lub cim tshiab thiab sai dua ntawm Intel QuickAssist Technology (QAT) coprocessors, uas muab kev txhawb nqa kho vajtse rau compression thiab encryption, yog lub luag haujlwm rau encrypting network kev khiav tsheb thiab kev sib pauv nrog cov subsystem cia. Thiab thaum kawg, "lub cav ntawm innovation" - , uas tsuas yog muaj rau OEMs.
Scalability thiab yooj
Cov cuab yeej tseem ceeb yog lub peev xwm xaiv tsis tau tsuas yog PCH kev sib txuas topology, tab sis kuj tseem yog qhov tseem ceeb ntawm cov peev txheej sab hauv ntawm cov nti hauv kev nkag mus rau cov kev sib txuas lus ceev nrog lub hauv paus processor (processors). Tsis tas li ntawd, nyob rau hauv tshwj xeeb EPO (EndPoint nkaus xwb hom), PCH kev twb kev txuas yog nqa tawm nyob rau hauv cov xwm txheej ntawm ib txwm PCI Express ntaus ntawv uas muaj 10 GbE cov kev pab cuam thiab Intel QAT. Nyob rau tib lub sijhawm, qhov classic DMI interface, nrog rau ntau qhov Legacy subsystems, pom hauv cov xim dub hauv daim duab, yog neeg xiam.
Sab hauv architecture ntawm Intel C620 PCH nti
Hauv txoj kev xav, qhov no ua rau nws tuaj yeem siv ntau dua ib qho Intel C620 PCH nti hauv ib qho system, scaling 10 GbE thiab Intel QAT functionality kom tau raws li qhov yuav tsum tau ua. Tib lub sijhawm, Txoj Cai Lij Choj uas xav tau tsuas yog nyob rau hauv ib daim ntawv luam nkaus xwb tuaj yeem qhib rau ntawm ib qho ntawm PCH chips tau teeb tsa.
Yog li, qhov kawg hais hauv kev tsim qauv yuav yog tus tsim tawm platform, ua raws li ob qho tib si thev naus laus zis thiab kev lag luam raws li qhov chaw ntawm txhua yam khoom tshwj xeeb.
