Sei iyo spec yakagadziridzwa?
Mainjiniya kubva kuOpen Compute Project (OCP) standard kumashure muna 2013. Akatsanangura modular uye yakavhurika dhizaini ye21-inch wide data center racks. Iyi nzira yakawedzera kushandiswa kunobudirira kweraki nzvimbo kusvika 87,5%. Kana tichienzanisa, 19-inch racks, iyo ndiyo chiyero nhasi, inongova 73%.
Pamusoro pezvo, mainjiniya akachinja nzira yekugovera magetsi. Iyo huru innovation yaive 12-volt bhazi umo michina yakabatana. Yakabvisa kukosha kwekuisa yayo yega magetsi kune yega yega server.
Yakabudiswa muna 2015 . Iine vagadziri kumuenzaniso we48-volt uye yakaderedza nhamba yevashanduri, iyo yakaderedza kushandiswa kwesimba re racks ne30%. Kutenda kune aya maficha, chiyero chave kupararira muindasitiri yeIT. Racks akatanga kushingaira makambani makuru eIT, makambani ekufonera uye mabhanga.
Munguva pfupi yapfuura, vanogadzira vakaunza imwe nyowani - Vhura Rack v3. Sekureva kwevanyori vechirongwa cheOCP, chiri kugadzirirwa nzvimbo dzakaremerwa dzedata dzinogadzira data yeAI neML masisitimu. Iyo hardware mhinduro dzakaitwa mavari dzine yakakwira simba dissipation density. Nokuda kwekushanda kwavo kunobudirira, dhizaini itsva yeraki yaidiwa.
Chii chinotozivikanwa nezve Open Rack v3
Vagadziri vanocherekedza kuti chiyero chitsva chichave chakanyanya kuchinjika uye chakasiyana-siyana kupfuura v2, uye zvakare ichatora zvese zvakanakisa kubva kune dzakapfuura shanduro - kushanda nesimba, modularity, compactness. Zvikuru sei, kuti icharamba ichishandisa 48-volt magetsi.
Magadzirirwo emagetsi matsva achada kuvandudza kutenderera kwemhepo uye kupisa kupisa. Nenzira, masisitimu emvura achashandiswa kutonhora michina. Nhengo dzeOCP pane dzakawanda mhinduro munzvimbo iyi. Kunyanya, maseketi ekusangana kwemvura, rack-akamisikidzwa kupisa kupisa, uye kunyudza masisitimu ari kugadzirwa.

Specification Developers , iyo mune ramangwana Vhura Rack v3 ichaderedza mari yeIT systems mu data centers. Ku Schneider Electric kuti iyo yechipiri vhezheni yemaracks yave kutodzikisa mari yekuchengetedza server ne25% zvichienzaniswa neyakajairwa rack magadzirirwo. Pane chikonzero chekutenda kuti iyo nyowani yakatarwa ichavandudza iyi nhamba.
Pakati pezvikanganiso zvechiyero, nyanzvi kuoma kwekugadzirisa midziyo uye makamuri emuchina kune zvaanoda. Pane mukana wekuti mutengo wekugadziridza maseva makamuri uchapfuura mabhenefiti kubva mukuita kwavo. Nechikonzero ichi, Vhura Rack inonyanya kutariswa pane nyowani data nzvimbo.

Zvizhinji kune zvakaipa dhizaini maficha emhinduro. Iyo yakavhurika rack architecture haipe dziviriro kubva kuguruva. Uyezve, inowedzera mukana wekukuvadza michina kana tambo.
Mapurojekiti akafanana
MunaKurume, imwe rondedzero yeracks yakaburitswa - ( Dhawunirodha faira rePDF kuti uone zvakatemwa). Gwaro iri rakagadzirwa muOpen19 Foundation, uko kubvira 2017 gadzirisa nzira dzekugadzira data data. Takataura nezvesangano iri zvakadzama mu .
Iyo Open19 System Level chiyero inotsanangura yepasirese fomu chinhu chemaracks uye inoseta zvinodiwa kunetiweki chimiro uye mashandisiro emagetsi. Chikwata cheOpen19 chinopa zano rekushandisa anonzi makeji ezvidhinha. Iwo mamodule ane akati wandei chassis maunogona kuisa iyo inodiwa Hardware - maseva kana ekuchengetedza masisitimu - mukusanganisa kusanganisa. Zvakare mukugadzira kune masherufu emagetsi, ma switch, network switch uye cable management system.
Kutonhodza, inonyudza system inoshandiswa. mvura yakaoma yakananga-ku-chip. Vanyori vepfungwa kuti iyo Open19 architecture inovandudza yakazara data centre simba rekuita ne10%.
Nyanzvi dzeindasitiri yeIT dzinotenda kuti mune ramangwana, mapurojekiti akaita seOpen19 uye Open Rack achaita kuti zvikwanise kukurumidza kuvaka nzvimbo dzedhata dzinochinjika dzekushanda neIoT mhinduro, zvinobatsira mukuvandudza tekinoroji ye5G uye peripheral computing.
