Baenjiniere ba tsoang ho Open Compute Project (OCP) standard morao ka 2013. O hlalositse moralo oa modular le o bulehileng oa liraka tsa setsi sa data tse 21-inch. Mokhoa ona o re lumelletse ho eketsa karo-karolelano ea sebaka sa rack se sebelisoang hantle ho 87,5%. Ha ho bapisoa, bakeng sa li-racks tsa 19-inch tse tloaelehileng kajeno, ke 73% feela.
Ho feta moo, baenjiniere ba ile ba fetola mokhoa oa ho tsamaisa motlakase. Ntho e ncha e ka sehloohong e ne e le bese ea 12-volt eo thepa e hokahaneng le eona. E ile ea felisa tlhokahalo ea ho kenya matla a eona bakeng sa seva ka seng.
E hlahisitsoe ka 2015 . Bahlahisi ho eona ho ea ho mohlala oa 48-volt le ho fokotsa palo ea li-transformer, tse fokotsang tšebeliso ea matla a rack ka 30%. Ka lebaka la likarolo tsena, maemo a se a atile indastering ea IT. Liraka li ile tsa qala ho sebetsa ka mafolofolo likoporasi tse kholo tsa IT, lik'hamphani tsa mehala le libanka.
Haufinyane tjena, bahlahisi ba hlahisitse tlhahiso e ncha - Open Rack v3. Ho ea ka bangoli ba morero oa OCP, e ntse e ntlafatsoa bakeng sa litsi tsa data tse ngata tse sebetsanang le lits'ebetso tsa AI le ML. Litharollo tsa hardware tse kentsoeng ho tsona li na le matla a phahameng a ho senya matla. Bakeng sa ts'ebetso ea bona e atlehileng, ho ne ho hlokahala moralo o mocha oa rack.
Seo se seng se tsejoa ka Open Rack v3
Bahlahisi ba hlokomela hore maemo a macha a tla fetoha habonolo le a bokahohleng ho feta v2, hape a tla nka tsohle tse ntle ho tsoa liphetolelong tse fetileng - ts'ebetso ea matla, modularity, compactness. Ka ho khetheha, hore e tla tsoelapele ho sebelisa matla a 48-volt.
Moqapi oa li-racks tse ncha o tla tlameha ho ntlafatsa ho potoloha ha moea le ho senya mocheso. Ka tsela, litsamaiso tsa metsi li tla sebelisoa ho pholisa lisebelisoa.

Baetsi ba lintlha , eo nakong e tlang Open Rack v3 e tla fokotsa litšenyehelo tsa mekhoa ea IT litsing tsa data. Ka Schneider Electric hore mofuta oa bobeli oa li-racks o se o ntse o ka fokotsa litšenyehelo tsa tlhokomelo ea seva ka 25% ha e bapisoa le meralo ea setso. Ho na le lebaka la ho lumela hore tlhaloso e ncha e tla ntlafatsa palo ena.
Har'a mefokolo ea maemo, litsebi bothata ba ho fetola lisebelisoa le likamore tsa mochini ho latela litlhoko tsa eona. Ho na le monyetla oa hore litšenyehelo tsa ho nchafatsa likamore tsa li-server li tla feta melemo e ka bang teng ea ts'ebetsong ea tsona. Ka lebaka lena, Open Rack e shebane haholo le litsi tse ncha tsa data.

Ho feta ho mathata moralo likarolo tsa tharollo. Mehaho ea liraka tse bulehileng ha e fane ka tšireletso lerōleng. Ho feta moo, monyetla oa lisebelisoa tse senyang kapa likhoele oa eketseha.
Merero e ts'oanang
Ka March, tlhaloso e 'ngoe ea li-racks e ile ea lokolloa - (ho sheba lintlha tseo u li hlokang ho khoasolla faele ea PDF). Tokomane e ntlafalitsoe ho Open19 Foundation, moo ho tloha ka 2017 tiisa mekhoa ea ho theha litsi tsa data. Re buile haholoanyane ka mokhatlo ona ka .
Tekanyetso ea Open19 System Level e hlalosa sebopeho sa bokahohle bakeng sa liraka le ho beha litlhoko tsa sebopeho sa marang-rang le tšebeliso ea matla. Sehlopha sa Open19 se fana ka maikutlo a ho sebelisa seo ho thoeng ke masaka a litene. Ke li-module tse nang le li-chassis tse 'maloa tseo ho tsona u ka behang lisebelisoa tse hlokahalang - li-server kapa litsamaiso tsa polokelo - ka motsoako o sa reroang. Moralo ona o boetse o kenyelletsa lishelefo tsa motlakase, li-switches, li-switches tsa marang-rang le sistimi ea taolo ea likhoele.
Sisteme ea ho qoelisoa e sebelisoa bakeng sa ho pholisa. ho toba ka ho toba ka metsi a omileng. Bangoli ba mohopolo hore meralo ea Open19 e eketsa katleho ea matla a setsi sa data ka 10%.
Litsebi tsa indasteri ea IT li lumela hore nakong e tlang, merero e kang Open19 le Open Rack e tla etsa hore ho khonehe ho aha kapele litsi tsa data tse feto-fetohang bakeng sa ho sebetsa le tharollo ea IoT mme e tla kenya letsoho ntlafatsong ea mahlale a 5G le komporo ea moeli.
