Kupa Simba Rakagadzikana reNVIDIA H200: Mashandisirwo Anoitwa MaCapacitors Kuvimbika kweNext-Generation AI Servers

Sezvo huwandu hwekudzidziswa kwemamodeli makuru uye fungidziro huri kuramba huchikura, makadhi eAI accelerator ari kupinda nekukurumidza muchikamu chitsva chekushandisa simba rakawanda kwazvo, simba rakawanda kwazvo, uye voltage yakaderera zvakanyanya.

Chizvarwa chitsva cheAI GPUs, chinomiririrwa neNVIDIA H200, chawedzera kushandiswa kwesimba rekadhi rimwe chete kusvika padanho re700W. Dambudziko guru nderekuchinja kubva pa "simba remakombiyuta pacharo" kuenda kusimba rekupa simba rehurongwa (PDN). Mumamiriro ezvinhu aya, zvikamu zvisingashande, kunyanya ma capacitor, zviri kufamba kubva kumashure kuenda pakati.

Mapoinzi Matatu Ekurwadziwa Kwenyika Chaiwo Akaunzwa neH200

Kune mainjiniya ehardware, H200 haisi GPU ine simba guru chete, asi bvunzo yakazara ye "mamiriro ekushanda akanyanya":

1. Mutoro Wenguva Pfupi: Kuchinja pakati pemutoro usina basa newakazara muAI computing kunoitika mumasekonzi mashoma, nepo core current ichisvetuka pakarepo kusvika kumazana kana kunyange zviuru zveamperes. Chero mhinduro inononoka inokonzera kudzikira kwevoltage, zvichikanganisa zvakananga kugadzikana kwecomputer.

2. Kupisa Kwakawanda uye Kushanda Kwenguva Refu: Simba re700W rinoshandiswa zvakanyanya mukati mepakeji uye nzvimbo yemodule. GPU inoshanda munzvimbo inodziya zvakanyanya ye85–105°C kwenguva yakareba uye inoda kushanda kwemaawa makumi maviri nemana pazuva, zvichiita kuti mudziyo ushande kwenguva yakareba.

3. Zvipingamupinyi zveMukati: GPU neHBM zvinotora nzvimbo yakawanda yebhodhi, zvichisiya nzvimbo shoma yemagetsi nemidziyo yekuparadzanisa. Kukwanisa kwakawanda, saizi diki, uye ESL/ESR yakaderera zvinova zvinodiwa zvakaoma.

Mhinduro dzeYMIN

Mumasystem akadaro, ma capacitor haasisiri "midziyo yekusefa" chete, asi zvivakwa zvakakosha zvekugadzirisa simba remakomputa:
Rutsigiro rweSimba Renguva Pfupi (Kubvisa Simba): MaCapacitor anopa muripo wemagetsi akakosha panguva pfupi VRM isati yapindura, zvichidzivirira kudonha kwemagetsi.

Kudzvinyirirwa kweRipple: Ruzha rwemagetsi runodzorwa mukati memazinga e millivolt pamagetsi akaderera kwazvo ekushanda e 0.7–0.8V, zvichiita kuti kuve nechokwadi chekuti kuverenga kwakarurama.

Kuvimbisika kwesimba remagetsi: Kuchengetedza kugadzikana kwenguva refu kwenetwork yemagetsi pasi pekupisa kwakanyanya, mutoro wakakwira, uye mamiriro ekushanda kwenguva refu.

Mumapuratifomu ekumhanyisa AI akadai seH200, kuvimbika kwecapacitor kunotsanangura zvakananga kusimba kwesimba remakombiyuta. Kune YMIN, macapacitor haasi zvikamu zvakazvimiririra chete, asi sisitimu yesimba inoshanda pamwe chete munzira yese yekupa simba reAI server.

Nzira yeKugadzirisa YMIN AI Server Capacitor

Takatarisana nematambudziko eH200 level, mhando imwe chete ye capacitor haichakwani.

YMIN inopa mhinduro yakakwana ye capacitor inosanganisira "simba remagetsi → bhodhi → GPU → system backup":

Mufananidzo 1: Dhayagiramu yemagetsi yeYMIN AI Server capacitor solution

YMIN inowana rutsigiro rwakagadzikana kune mitoro inodarika nguva, kupisa kwakanyanya, uye kushanda maawa makumi maviri nemana pazuva, mazuva manomwe pasvondo nekushandisa matekinoroji akasiyana-siyana e capacitor mukubatana pakati pemazinga akasiyana emagetsi uye mabhendi ema frequency.

Mhedziso: Munguva yesimba remakombiyuta, kugadzikana kwakakosha zvakaenzana.

Makwikwi esimba reAI computing haasiri ekugadzira maGPU chete uye magadzirirwo, asiwo ekuvimbika kwema network emagetsi. Mumapuratifomu epamusoro eAI akadai seH200, mashandiro uye hupenyu hwe capacitor imwe chete zvinogona kusarudza kugadzikana kwekushanda kwesevha. YMIN inotarisa pakupa mhinduro dze capacitor dzakavimbika uye dzinogara kwenguva refu dzema AI servers, ichiva nechokwadi chekuti watt yega yega yesimba recomputer yakavakirwa pahwaro hwesimba rakasimba.
