Gutanga Ingufu Zihamye kuri NVIDIA H200: Uburyo Capacitors Isobanura Kwizerwa kwa Seriveri za AI zo mu Gihe Gikurikira

Uko urwego rw'amahugurwa manini n'isuzumabumenyi bikomeje kwaguka, amakarita accelerator ya AI arimo kwinjira vuba mu cyiciro gishya cy'ikoreshwa ry'ingufu nyinshi cyane, umuriro mwinshi cyane, na voltage nke cyane.

Itsinda rishya rya AI GPU, rihagarariwe na NVIDIA H200, ryashyize ingufu zikoreshwa ku ikarita imwe ku rwego rwa 700W. Ikibazo nyacyo ni uguhinduka kuva ku "ngufu z'ikoranabuhanga ubwazo" kugera ku buryo buhamye bwo gutanga ingufu ku rwego rwa sisitemu (PDN). Muri uru rwego, ibice bidakora, cyane cyane capacitors, birimo kuva inyuma y'ishusho bijya mu gice cy'imbere.

Ingingo eshatu z'ububabare bw'isi nyakuri zazanywe na H200

Ku bahanga mu byuma, H200 si GPU ikomeye cyane gusa, ahubwo ni ikizamini cyuzuye cy' "imiterere y'imikorere ikabije":

1. Umutwaro w'igihe gito cyane: Guhinduranya hagati y'umutwaro utagira icyo ukora n'umutwaro wuzuye muri mudasobwa ya AI bibaho mu masegonda make, aho umuyoboro w'amashanyarazi uhita uzamuka ukagera kuri amagana cyangwa ibihumbi bya ampere. Uburyo ubwo aribwo bwose bwo gusubiza buhoro buzatuma voltage igabanuka, bigira ingaruka ku buryo butaziguye ku mikorere ya mudasobwa.

2. Ubushyuhe bwinshi n'imikorere y'igihe kirekire: Ikoreshwa ry'ingufu rya 700W rigizwe n'ahantu hato cyane ho gupakira no gukoresha module. GPU ikora ahantu hari ubushyuhe bwinshi bwa 85–105°C mu gihe kirekire kandi isaba gukora amasaha 24/7, ibi bikaba bisaba cyane igihe cyose igikoresho kimaze.

3. Imbogamizi z'umwanya: GPU na HBM byiganje mu mwanya munini w'ibyuma, bigatuma ahantu hato cyane ho gutanga amashanyarazi n'ibikoresho byo gukuraho. Ubushobozi bwinshi, ingano nto, na ESL/ESR nkeya biba ibisabwa bikomeye.

Ibisubizo bya YMIN

Muri ubwo buryo, capacitors ntabwo zikiri "ibikoresho byo kuyungurura" gusa, ahubwo ni ibikorwa remezo by'ingenzi mu gutuma ingufu ziguma neza:
Inkunga y'Ingufu z'Igihe Gito (Gukuraho): Capacitors zitanga indishyi y'amashanyarazi y'ingenzi mu kanya gato mbere yuko VRM isubiza, bikarinda kugwa k'amashanyarazi.

Guhagarika imirasire y'amazi: Urusaku rw'amashanyarazi rugenzurwa mu rugero rwa millivolt ku muvuduko uri hasi cyane wa 0.7–0.8V, bigatuma imibare iba ikora neza.

Icyizere cyo ku rwego rwa sisitemu: Kubungabunga umutekano w'umuyoboro w'amashanyarazi mu gihe kirekire mu gihe cy'ubushyuhe bwinshi, umutwaro mwinshi, n'igihe kirekire cyo gukora.

Mu buryo bwo kwihutisha AI nka H200, kwizerwa kwa capacitor ni byo bigaragaza neza uburyo ingufu za mudasobwa zikomeza. Kuri YMIN, capacitors si ibice byigenga gusa, ahubwo ni sisitemu y'ingufu ikorana mu buryo bufatika mu nzira yose y'amashanyarazi ya seriveri ya AI.

Uburyo bwo gukemura ikibazo cya YMIN AI Server Capacitor

Uhanganye n'ibibazo byo mu rwego rwa H200, ubwoko bumwe bwa capacitor ntibukihagije.

YMIN itanga igisubizo cyuzuye cya capacitor gikubiyemo "amashanyarazi → urwego rw'ikibaho → GPU → backup ya sisitemu":

Ishusho ya 1: Ishusho y'amashanyarazi ya YMIN AI Server capacitor solution

YMIN igeraho ishyigikira imizigo ihoraho y’igihe gito cyane, ubushyuhe bwinshi, no gukora amasaha 24/7 binyuze mu gukoresha ikoranabuhanga ritandukanye rya capacitor mu guhuza urwego rw’amashanyarazi n’imirongo y’amajwi.

Umwanzuro: Mu gihe cy'ingufu za mudasobwa, guhagarara neza nabyo ni ingenzi.

Irushanwa ry’ingufu za mudasobwa za AI ntirikiri ku buryo bwo gukora no kubaka GPU gusa, ahubwo rinareba uburyo bwo kwizerwa bw’imiyoboro y’amashanyarazi. Mu buryo bwa AI bwo ku rwego rwo hejuru nka H200, imikorere n’igihe cya capacitor imwe bishobora kugena uburyo seriveri yose ihagaze neza. YMIN yibanda ku gutanga ibisubizo byizewe kandi birambye bya capacitor kuri seriveri za AI, igenzura ko watt yose y’ingufu za mudasobwa yubakwa ku rufatiro rw’ingufu ruhamye.
