Ka meralo ea li-platform tsa x86, ho hlahile mekhoa e 'meli e tlatsanang. Ho latela mofuta o mong, re hloka ho fetela ho ho kopanya lisebelisoa tsa komporo le ho laola chip e le 'ngoe. Mokhoa oa bobeli o khothaletsa kabo ea boikarabello: processor e na le bese e sebetsang hantle e etsang "peripheral scalable ecosystem". E theha motheo oa Intel C620 system logic topology bakeng sa li-platform tsa boemo bo holimo.
Phapang ea mantlha ho tsoa ho chipset ea Intel C610 e fetileng ke katoloso ea mocha oa puisano lipakeng tsa processor le li-peripherals tse kenyellelitsoeng ho chip ea PCH ka ts'ebeliso ea likhokahano tsa PCIe hammoho le bese ea setso ea DMI.
Ha re shebisiseng boqapi ba borokho bo ka boroa ba Intel Lewisburg: ke mekhoa efe ea phetoho le phetoho e atolositseng matla a eona a ho buisana le li-processor?
Liphetoho tsa phetoho puisanong ea CPU-PCH
E le karolo ea mokhoa oa ho iphetola ha lintho, mocha o moholo oa puisano pakeng tsa CPU le borokho bo ka boroa, e leng bese ea DMI (Direct Media Interface), e fumane tšehetso bakeng sa mokhoa oa PCIe x4 Gen3 ka ts'ebetso ea 8.0 GT / S. Pejana, ho Intel C610 PCH, puisano lipakeng tsa processor le logic ea sistimi e ne e etsoa ka mokhoa oa PCIe x4 Gen 2 ho bandwidth ea 5.0 GT/S.
Papiso ea ts'ebetso ea logic ea tsamaiso ea Intel C610 le C620
Hlokomela hore subsystem ena e baballa haholo ho feta likou tsa PCIe tse hahelletsoeng ka har'a processor, tseo hangata li sebelisetsoang ho hokahanya li-drive tsa GPU le NVMe, moo PCIe 3.0 e sebelisitsoeng nako e telele mme ho reriloe phetoho ea PCI Express Gen4.
Liphetoho tsa phetoho puisanong ea CPU-PCH
Liphetoho tsa phetoho li kenyelletsa tlatsetso ea liteishene tse ncha tsa puisano tsa PCIe CPU-PCH, tse bitsoang Li-uplink tse eketsehileng. Ka 'mele, tsena ke likou tse peli tsa PCI Express tse sebetsang ka mekhoa ea PCIe x8 Gen3 le PCIe x16 Gen3, ka bobeli 8.0 GT/S.
Bakeng sa tšebelisano lipakeng tsa CPU le Intel C620 PCH, ho sebelisoa libese tse 3: DMI le likou tse peli tsa PCI Express.
Hobaneng ho ne ho hlokahala ho nchafatsa topology e teng ea puisano le Intel C620? Ntlha ea pele, ho fihlela ho balaoli ba marang-rang ba 4x 10GbE ba nang le ts'ebetso ea RDMA ba ka kopanngoa le PCH. Taba ea bobeli, moloko o mocha le o potlakileng oa li-coprocessors tsa Intel QuickAssist Technology (QAT), tse fanang ka tšehetso ea hardware bakeng sa compression le encryption, li na le boikarabello ba ho patala sephethephethe sa marang-rang le phapanyetsano le sistimi ea polokelo. 'Me qetellong, "enjene ea boqapi" - , e tla fumaneha feela ho li-OEM.
Scalability le ho tenyetseha
Thepa ea bohlokoa ke bokhoni ba ho khetha ka boikhethelo eseng feela topology ea khokahano ea PCH, empa hape le lintho tse tlang pele ho lisebelisoa tsa ka hare tsa chip ho fihlella likanale tsa puisano tse potlakileng le processor e bohareng (bahlahisi). Ho phaella moo, ho EPO e khethehileng (EndPoint Only Mode), khokahanyo ea PCH e etsoa boemong ba mochine o tloaelehileng oa PCI Express o nang le lisebelisoa tsa 10 GbE le Intel QAT. Ka nako e ts'oanang, sebopeho sa DMI sa khale, hammoho le li-subsystem tse 'maloa tsa Lefa, tse bonts'itsoeng ka botšo setšoantšong, li holofetse.
Mehaho ea ka hare ea chip ea Intel C620 PCH
Ka khopolo, sena se etsa hore ho khonehe ho sebelisa Intel C620 PCH chip e fetang e le 'ngoe tsamaisong, ho eketsa ts'ebetso ea 10 GbE le Intel QAT ho finyella litlhoko tsa tshebetso. Ka nako e ts'oanang, mesebetsi ea Legacy e hlokahalang ka kopi e le 'ngoe feela e ka lumelloa ho e' ngoe ea li-chips tsa PCH tse kentsoeng.
Kahoo, polelo ea ho qetela ea moralo e tla ba ea moqapi oa sethala, ea sebetsang motheong oa lintlha tsa theknoloji le tsa papatso ho latela boemo ba sehlahisoa se seng le se seng.
