Product Overview
I-Trusted® TMR Expander Processor Module ihlala kwiindawo zokubeka iprosesa yeTrusted Expander Chassis kwaye ibonelela ngojongano 'lwekhoboka' phakathi kwe-Expander Bus kunye ne-Expander Chassis Backplane.I-Expander Bus ivumela iinkqubo ezininzi ze-chassis ukuba ziphunyezwe kusetyenziswa uqhagamshelwano lwentambo ye-Unshielded Twisted Pair (UTP) ngelixa igcina i-fault tolerant, high bandwidth Inter-Module Bus (IMB) amandla.

IModyuli ibonelela ngesiqulatho sempazamo kwiBhasi ye-Expander, iModyuli ngokwayo kunye ne-Expander
I-Chassis, iqinisekisa ukuba iziphumo zezi mpazamo zinokuthi zenziwe zasekhaya kunye nokufumaneka kwenkqubo kwandiswe.Imodyuli iyanyamezela impazamo ngoyilo lweHIFT TMR.Uxilongo olubanzi, ukubeka iliso kunye novavanyo lubonelela ngokuchongwa kwempazamo ngokukhawuleza.I-Hot-standby kunye nemodyuli esecaleni
uqwalaselo luyaxhaswa, luvumela amacebo okulungisa oluzenzekelayo kunye nezandla Amanqaku:

• I-Triple Modular Redundant (TMR), ukunyamezela iimpazamo (3-2-0) ukusebenza.
• Uyilo lwe-Hardware eSetyenziselwe iFault (HIFT).
• I-hardware ezinikeleyo kunye nenkqubo yovavanyo lwesoftware ebonelela ngokukhawuleza kakhulu ukuqaphela iimpazamo kunye
amaxesha okuphendula.
• Ukuphatha iimpazamo ezizenzekelayo ngaphandle kwenkathazo eyothusayo.
• Ukutshintshwa okushushu.
• Iimpawu zePhaneli ePhambili ezibonisa impilo kunye nobume bemodyuli.

1.1.Isishwankathelo
Iprosesa ye-TMR ye-Expander yidizayini yokunyamezela impazamo esekelwe kwi-architecture ye-TMR ehlelwe kwi-lock-step configuration.Umzobo we-1 ubonisa, ngokwemigaqo elula, isakhiwo esisisiseko se-TMR Expander Processor.
IModyuli ineengingqi ezintathu ezingundoqo zokukhusela (i-FCR A, B kunye no-C).I-FCR nganye ephambili iqulethe i-interfaces kwi-Expander Bus kunye ne-Inter-Module Bus (IMB), i-interface esebenzayo / yokulinda enye i-TMR Expander Processor kwi-Chassis, ingqiqo yokulawula, i-transceivers yonxibelelwano kunye nombane.
Unxibelelwano phakathi kweModyuli kunye neProcessor yeTMR kusetyenziswa iModyuli ye-Expander Interface Module kunye nebhasi ye-Expander ephindwe kathathu.I-Expander Bus iphindwe kathathu, i-point-to-point architecture.Itshaneli nganye ye-Expander Bus iquka umyalelo ohlukeneyo kunye neendaba zokuphendula.Ukuvota kubonelelwe kwi-Expander Bus Interface ukuqinisekisa ukuba iziphene zentambo ziyanyamezelwa, kwaye intsalela ye-Expander Processor isebenza ngendlela ephindwe kathathu, nokuba kukho iimpazamo zentambo.
Unxibelelwano phakathi kweModyuli kunye neeModyuli ze-I / O kwi-Expander Chassis ihamba nge-IMB kwi-Backplane ye-Expander Chassis.I-IMB iyafana naleyo ngaphakathi kwi-Controller Chassis, ebonelela ngokunyamezela okufanayo, unxibelelwano oluphezulu lwe-bandwidth phakathi kwe-Interface Modules kunye ne-TMR Processor.Njengakwi-Expander Bus Interface zonke iintengiselwano zivotelwe, iimpazamo zokubekwa kwindawo kwi-IMB xa zinokuthi zenzeke.
I-FCR yesine (i-FCR D) inikezela ngokubeka iliso okungabalulekanga kunye nokubonisa imisebenzi kwaye ikwayinxalenye ye-inter-FCR ye-Byzantine yokuvota.
Ukwahlulwa kubonelelwa phakathi kwe-FCR naphi na apho kufuneka khona ujongano, ukuqinisekisa ukuba iziphene azikwazi ukusasaza phakathi kwazo.

1.2.Ukusasazwa kwamandla
Imodyuli ye-TMR Expander Processor ifumana amandla ayo ombane angaphakathi ukusuka kwi-dual redundant +24 Vdc amandla anikezelwe ngesidibanisi semodyuli esuka kwiTrusted Expander Chassis Backplane.I-FCR nganye ifumana izinto ezifunekayo ngokuzimeleyo.
