Pehea e koho ai i ka PLP Capacitor kūpono loa no nā AI Server SSDs? He loiloi piha o nā Conductive Polymer Tantalum Electrolytic Capacitors a me nā Solid-Liquid Hybrid Aluminum Electrolytic Capacitors

 

Ma nā kikowaena AI, ʻo SSD ka ʻāpana koʻikoʻi no ka mālama ʻana a me ka loaʻa ʻana o ka ʻikepili, a pili pololei kā lākou hana i ka hoʻomaʻamaʻa a me ka pono o ka inference. Me ka hoʻohana nui ʻia ʻana o nā interfaces PCIe 5.0/6.0, ua piʻi nui ka hoʻohana ʻana i ka mana SSD a me nā koi o kēia manawa koke, e hana ana i ke koho ʻana o nā capacitors Power Loss Protection (PLP) he mea nui no ke kūpaʻa o ka ʻōnaehana.

ʻOi loa aku ma lalo o nā kūlana o ke kiʻekiʻe o ka mahana, ke kaumaha kiʻekiʻe, a me ka hana mau 24/7, pono nā capacitors e hoʻokō i nā koi he nui i ka manawa like, me ka ESR haʻahaʻa, ka nui o ka capacitance kiʻekiʻe, ke ola lōʻihi, a me ke kūpaʻa o ka mahana kiʻekiʻe. A i ʻole, hiki ke nalowale ka ʻikepili, ka palaho firmware, a i ʻole nā ​​​​​​pōʻino ʻōnaehana.

No ke aha e pili pololei ai ke koho ʻana o ka Capacitor i ka hana SSD a me ke ola

Ke loaʻa i kahi SSD kahi pio uila koke, pono ka capacitor PLP e hoʻokuʻu i kona ikehu i mālama ʻia i loko o nā milliseconds e hōʻoia i ke kākau palekana ʻana o ka ʻikepili i ka hoʻomanaʻo flash NAND. Inā kiʻekiʻe loa ka ESR o ka capacitor, e hāʻule nui ka voltage i ka wā o ka hoʻokuʻu ʻana, e alakaʻi paha i ka hāʻule ʻana o ke kākau ʻana. Inā lawa ʻole ka capacitance a i ʻole e palaha nui ka waiwai capacitance i nā mahana kiʻekiʻe, ʻaʻole hiki iā ia ke hāʻawi i ka manawa paʻa kūpono. Eia kekahi, i nā SSD M.2 compact (e laʻa, 5mm ka mānoanoa), ua kaupalena pinepine ʻia ke kiʻekiʻe o ka capacitor ma lalo o 1.9mm, a ʻo ka pono volumetric (waiwai CV) e hoʻoholo pololei inā hiki ke hoʻokō ʻia ka mālama ikehu lawa i loko o kahi palena.

Nā Hoʻonā Capacitor YMIN

Ke uhaki nei i nā bottlenecks mālama e hoʻokō i nā pono o ka wā AI

Hoʻonā A: Nā Capacitors Electrolytic Tantalum Polymer Conductive - He Benchmark no ka Hana Lewa Loa

ʻO nā capacitors electrolytic tantalum polymer conductive TQD series a YMIN, me kā lākou hoʻolālā lahilahi loa (1.5mm), he kūpono loa ia no nā SSD M.2 lahilahi loa, e hoʻoponopono ana i ka pilikia palena wahi. ʻO ke kumukūʻai CV kiʻekiʻe (1.0μF/mm³) a me ke kūpaʻa wela kiʻekiʻe o nā capacitors tantalum e hōʻoiaʻiʻo ana ʻoiai i loko o kahi liʻiliʻi loa, hiki iā lākou ke hāʻawi i ka ikehu pale mana lawa no ka SSD, e hōʻoiaʻiʻo ana i kāna hana paʻa no ka manawa lōʻihi ma lalo o ke ana wela kiʻekiʻe a me nā wahi ukana kiʻekiʻe.

Lahilahi loa a me ka nui o ka mānoanoa: ʻOMoʻo TQDhiki ke haʻahaʻa e like me 1.5mm ke kiʻekiʻe a he kiʻekiʻe kona waiwai CV e like me 1.0μF/mm³, e lilo ia i koho kūpono no nā SSD M.2 lahilahi loa.

Paʻa a Paʻa: He ʻano paʻa hou, he ʻano nui piha me ke ola e ʻoi aku ana ma mua o 100,000 mau hola ma 75°C, a ua hala i nā hoʻāʻo pālua 85°C, e mālama ana i ke kūpaʻa ma lalo o nā kūlana mahana a me ka haʻahaʻa kiʻekiʻe no ka wā lōʻihi.

Hana Paʻa: Hōʻike ka ʻikepili pakuhi i nā loli liʻiliʻi i ka capacitance (C) a me ke kū'ē ʻana o ka moʻo like (ESR) me ka manawa a me ka mahana, e hāʻawi ana i ka palekana mau a hilinaʻi hoʻi.

Ola lōʻihi a me ke kūpaʻa kiʻekiʻe o ke aniau: He ʻano paʻa piha me ka lōʻihi o ke ola i manaʻo ʻia e ʻoi aku ma mua o 100,000 mau hola ma 75°C. ʻO nā ana pale makū he nui e hōʻoia i ka hala ʻana o ka huahana i nā hoʻāʻo mahana a me ka makū pālua he 85°C, kūpono no ka hana paʻa ma lalo o nā ukana wela kiʻekiʻe no ka manawa lōʻihi.

Kiʻi 1: Ka Hoʻololi LC o kahi Capacitor Tantalum 35V 68μF i ka hala ʻana o ka manawa

Kiʻi 2: ʻO ka loli ESR o kahi capacitor tantalum 35V 68μF i ka hala ʻana o ka manawa

Kiʻi 3: Ka loli o ΔC/Co i ka hala ʻana o ka manawa no kahi capacitor tantalum 35V 68μF

Koho B: Nā Capacitors Electrolytic Aluminum Hybrid Polymer - He Koho Kiʻekiʻe no ka Hilinaʻi Kiʻekiʻe a me ke Kumukūʻai Kūpono

No nā SSD papa ʻoihana e koi ana i nā mana nui, ʻo nā capacitors electrolytic alumini hybrid polymer a ymin kahi koho kūpono ma muli o ko lākou kumukūʻai kiʻekiʻe. Hāʻawi lākou i kahi ola lōʻihi loa o 10,000 mau hola ma 105 ℃, e mālama ana i ka ESR haʻahaʻa a me ke kūpaʻa maikaʻi o ka mana ʻoiai ma nā wahi me nā loli wela koʻikoʻi.

Lōʻihi a paʻa: Ke hāʻawi nei ma mua o 10,000 mau hola o ka hana ma 105 ℃, e hoʻokō ana i nā pono hana lōʻihi o nā kikowaena.

Pili ka ʻōnaehana: ʻO ke ʻano hāʻule he "kaapuni hāmama," e hāʻawi ana i ka ʻoi aku ka palekana no nā ʻōnaehana mālama ʻikepili waiwai nui i hoʻohālikelike ʻia me ke ʻano kaapuni pōkole.

Ka pōmaikaʻi o ke kumukūʻai: Hoʻonui nui i nā kumukūʻai BOM me ka hoʻokō ʻana i ka hana like, e lilo ia i koho maikaʻi loa no nā SSD nui a me nā SSD ʻoihana nui.
