Njengoba ubukhulu bokuqeqeshwa kwamamodeli amakhulu kanye nokuqagela kuqhubeka nokukhula, amakhadi okusheshisa e-AI angena ngokushesha esigabeni esisha sokusetshenziswa kwamandla aphezulu kakhulu, amandla kagesi aphezulu kakhulu, kanye ne-voltage ephansi kakhulu.
Isizukulwane esisha sama-AI GPU, amelelwe yi-NVIDIA H200, sinyuse ukusetshenziswa kwamandla kwekhadi elilodwa kwaya ezingeni lika-700W. Inselele yangempela ukushintsha kusuka “kumandla okusebenzisa ikhompyutha uqobo” kuya ekuzinzeni kwenethiwekhi yokulethwa kwamandla ezingeni lesistimu (PDN). Kulesi simo, izingxenye ezingasebenzi, ikakhulukazi ama-capacitor, zisuka ngemuva kwezigcawu ziye enkabeni.
Amaphuzu Amathathu Obuhlungu Emhlabeni Wangempela Alethwe yi-H200
Konjiniyela behadiwe, i-H200 akuyona nje i-GPU enamandla kakhulu, kodwa isivivinyo esiphelele "sezimo zokusebenza ezimbi kakhulu":
1. Umthwalo Owesikhashana Owedlulele: Ukushintshana phakathi komthwalo ongasebenzi kanye nomthwalo ogcwele ekubalweni kwe-AI kwenzeka ngemizuzwana emi-nano, lapho ugesi oyinhloko ugxuma khona manjalo uye kumakhulu noma ngisho nezinkulungwane zama-ampere. Noma yikuphi ukusabela okuhamba kancane kuzobangela ukwehla kwamandla kagesi, okuthinta ngqo ukuzinza kwekhompyutha.
2. Ubuningi Bokushisa Okuphezulu kanye Nokusebenza Kwesikhathi Eside: Ukusetshenziswa kwamandla angu-700W kugxile ngaphakathi kwephakeji encane kakhulu kanye nesikhala semojuli. I-GPU isebenza endaweni yokushisa ephezulu engu-85–105°C isikhathi eside futhi idinga ukusebenza okungaphazanyiswa amahora angu-24/7, okubeka izidingo eziphezulu kakhulu esikhathini sokuphila kwedivayisi.
3. Izithiyo Zesikhala: I-GPU ne-HBM zithatha indawo enkulu ebhodini, zishiya indawo encane kakhulu yezinsiza zikagesi namadivayisi okuxhumanisa. Amandla aphezulu, usayizi omncane, kanye ne-ESL/ESR ephansi kuba yizidingo eziqinile.
Izixazululo ze-YMIN
Kulezi zinhlelo, ama-capacitor awaseyona nje "imishini yokuhlunga," kodwa ayingqalasizinda ebalulekile yokuqina kwamandla ekhompyutha:
Ukusekelwa Kwamandla Esikhashana (Ukuhlukanisa): Ama-capacitor ahlinzeka ngesinxephezelo samandla abalulekile ngokushesha ngaphambi kokuba i-VRM iphendule, okuvimbela ukuwa kwamandla kagesi.
Ukucindezela Ukuqhekeka: Umsindo wokunikezwa kwamandla ulawulwa ngaphakathi kwamazinga e-millivolt nge-voltage yokusebenza ephansi kakhulu engu-0.7–0.8V, okuqinisekisa ukunemba kokubala.
Isiqinisekiso sokuthembeka kwezinga lesistimu: Ukugcina ukuzinza kwesikhathi eside kwenethiwekhi yokunikezwa kwamandla ngaphansi kwezimo zokushisa eziphakeme, umthwalo ophezulu, kanye nezimo zokusebenza zesikhathi eside.
Kumapulatifomu okusheshisa i-AI njenge-H200, ukuthembeka kwe-capacitor kuchaza ngqo ukusimama kwamandla okusebenzisa ikhompyutha. Ku-YMIN, ama-capacitor akuzona nje izingxenye ezizimele, kodwa kunalokho uhlelo lwamandla olusebenza ngokubambisana kuyo yonke indlela yokunikezwa kwamandla yeseva ye-AI.
Indlela Yesixazululo Se-YMIN AI Server Capacitor
Njengoba sibhekene nezinselele zezinga le-H200, uhlobo olulodwa lwe-capacitor alusanele.
I-YMIN inikeza ikhambi eliphelele le-capacitor elihlanganisa “ukunikezwa kwamandla → izinga lebhodi → i-GPU → isipele sesistimu”:
Umfanekiso 1: Umdwebo wokunikezwa kwamandla wesisombululo se-capacitor se-YMIN AI Server
I-YMIN ithola ukwesekwa okuzinzile kwemithwalo yesikhashana eyedlulele, ukushisa okuphezulu, kanye nokusebenza amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto ngokusebenzisa ubuchwepheshe obuhlukahlukene be-capacitor ngokusebenzisana kuwo wonke amazinga e-voltage ahlukene kanye nama-frequency band.
Isiphetho: Esikhathini samandla okusebenzisa ikhompyutha, ukuzinza kubaluleke ngokulinganayo.
Umncintiswano wamandla okubala e-AI awuseyona nje izinqubo zokukhiqiza ze-GPU kanye nezakhiwo, kodwa futhi uphathelene nokuthembeka kwamanethiwekhi okuphakelwa kwamandla. Kumapulatifomu e-AI aphezulu njenge-H200, ukusebenza kanye nesikhathi sokuphila kwe-capacitor eyodwa kunganquma ukuzinza kokusebenza kweseva yonke. I-YMIN igxile ekuhlinzekeni ngezixazululo ze-capacitor ezithembekile nezizinzile zamaseva e-AI, ukuqinisekisa ukuthi wonke ama-watt wamandla okubala akhiwe esisekelweni samandla esizinzile.
