Chifukwa chiyani chowonjezeracho chasinthidwa?
Mainjiniya ochokera ku Open Compute Project (OCP) standard kumbuyo mu 2013. Adalongosola mawonekedwe osinthika komanso otseguka a 21-inch wide data racks. Njirayi yawonjezera kugwiritsa ntchito bwino malo opangira rack mpaka 87,5%. Poyerekeza, ma rack 19-inchi, omwe ali muyeso masiku ano, ndi 73% yokha.
Kuphatikiza apo, mainjiniya asintha njira yogawa magetsi. Chatsopano chachikulu chinali basi ya 12-volt yomwe zidazo zimalumikizidwa. Icho chinathetsa kufunika koyika mphamvu yake yokha pa seva iliyonse.
Inatulutsidwa mu 2015 . Lili ndi opanga ku chitsanzo cha 48-volt ndikuchepetsa chiwerengero cha ma transformer, omwe amachepetsa mphamvu yamagetsi ndi 30%. Chifukwa cha izi, mulingo wakula kwambiri mumakampani a IT. Racks anayamba mwachangu makampani akuluakulu a IT, makampani olankhulana ndi mafoni ndi mabanki.
Posachedwapa, Madivelopa abweretsa mawonekedwe atsopano - Open Rack v3. Malinga ndi olemba ntchito ya OCP, ikupangidwira malo osungira deta omwe amakonza deta ya machitidwe a AI ndi ML. Mayankho a hardware omwe akugwiritsidwa ntchito mwa iwo ali ndi mphamvu zambiri zowonongeka. Kuti agwire bwino ntchito, adafunika kupanga mapangidwe atsopano.
Zomwe zimadziwika kale za Open Rack v3
Madivelopa amazindikira kuti mulingo watsopanowu udzakhala wosinthika komanso wosunthika kuposa v2, ndipo utenganso zabwino zonse kuchokera kumitundu yam'mbuyomu - kugwiritsa ntchito mphamvu, modularity, compactness. Makamaka, kuti ipitiliza kugwiritsa ntchito magetsi a 48-volt.
Mapangidwe a ma racks atsopano adzafunika kupititsa patsogolo kayendedwe ka mpweya ndi kutaya kutentha. Mwa njira, machitidwe amadzimadzi adzagwiritsidwa ntchito kuziziritsa zida. Mamembala a OCP pa mayankho angapo m'derali. Makamaka, mabwalo olumikizana ndi madzi, zosinthira zotenthetsera zoyika pa rack, ndi makina omiza akupangidwa.

Specification Madivelopa , yomwe m'tsogolomu Open Rack v3 idzachepetsa mtengo wa machitidwe a IT m'malo opangira deta. Ku Schneider Electric kuti mtundu wachiwiri wa ma racks ukuchepetsa kale mtengo wokonza seva ndi 25% poyerekeza ndi mapangidwe achikhalidwe. Pali chifukwa chokhulupirira kuti mawonekedwe atsopanowa adzawongolera chiwerengerochi.
Pakati pa zofooka za muyezo, akatswiri zovuta zosinthira zida ndi zipinda zamakina pazofunikira zake. Pali kuthekera kuti mtengo wokonzanso zipinda za seva udzapitilira phindu lomwe lingakhalepo pakukhazikitsa kwawo. Pachifukwa ichi, Open Rack imayang'ana kwambiri malo atsopano a data.

Zambiri pazoyipa mawonekedwe a yankho. Zomangamanga zotseguka sizimapereka chitetezo ku fumbi. Kuphatikiza apo, zimawonjezera mwayi wowononga zida kapena zingwe.
Ntchito zofanana
M'mwezi wa Marichi, chidziwitso china cha ma racks chinatulutsidwa - (Tsitsani fayilo ya PDF kuti muwone mawonekedwe). Chikalatacho chidapangidwa ku Open19 Foundation, komwe kuyambira 2017 sinthani njira zopangira ma data center. Tinakambirana za bungweli mwatsatanetsatane mu .
Muyezo wa Open19 System Level umalongosola mawonekedwe achilengedwe chonse cha ma racks ndikuyika zofunikira pamapangidwe a netiweki ndikugwiritsa ntchito mphamvu. Gulu la Open19 likuwonetsa kugwiritsa ntchito zomwe zimatchedwa makola a njerwa. Ndiwo ma module okhala ndi ma chassis angapo momwe mungayikitsire zida zofunika - ma seva kapena makina osungira - mosakanikirana mosagwirizana. Komanso pamapangidwewo pali mashelufu amphamvu, zosintha, zosinthira maukonde ndi makina owongolera chingwe.
Pozizira, njira yomiza imagwiritsidwa ntchito. madzi owuma mwachindunji-to-chip. Olemba malingaliro kuti kamangidwe ka Open19 kumapangitsa kuti pakhale mphamvu zamagetsi pakatikati pa data ndi 10%.
Akatswiri amakampani a IT amakhulupirira kuti mtsogolomo, ma projekiti ngati Open19 ndi Open Rack apangitsa kuti zitheke kupanga mwachangu malo osinthika a data kuti agwire ntchito ndi mayankho a IoT, amathandizira pakupanga ukadaulo wa 5G ndi makompyuta ozungulira.
