🥇Vula I-Rack v3: yini ongayilindela esilinganisweni esisha se-server rack Architecture

Izothola isicelo kuzikhungo zedatha ye-hyperscale.

Kungani i-spec ibuyekeziwe?

Onjiniyela abavela ku-Open Compute Project (OCP) yethula inguqulo yokuqala ejwayelekile emuva ngo-2013. Uchaze idizayini eyimodulayo nevulekile yamaracks esikhungo sedatha esibanzi esingama-intshi angu-21. Le ndlela ikhuphule ukusetshenziswa ngempumelelo kwendawo yokubeka ama-rack yafinyelela ku-87,5%. Ngokuqhathanisa, ama-racks angu-19-intshi, okuyizinga elijwayelekile namuhla, angama-73% kuphela.

Ukwengeza, onjiniyela baye bashintsha indlela yokusabalalisa amandla. Into emisha eyinhloko kwakuyibhasi engu-12-volt lapho okokusebenza kuxhunywe khona. Isuse isidingo sokufaka ugesi wayo kuseva ngayinye.

Ikhishwe ngo-2015 inguqulo yesibili yezinga. Iqukethe onjiniyela sebewelile kumodeli ye-48-volt futhi yehlisa inani lama-transformer, okunciphisa ukusetshenziswa kwamandla kwama-rack ngo-30%. Ngenxa yalezi zici, izinga selisakazeke kabanzi embonini ye-IT. Ama-Racks aqale ngokusebenza sebenzisa izinkampani ezinkulu ze-IT, izinkampani zezokuxhumana namabhange.

Muva nje, abathuthukisi bethule ukucaciswa okusha - I-Open Rack v3. Ngokusho kwababhali bohlelo lwe-OCP, lwenzelwe izikhungo zedatha ezinomthwalo omkhulu ezicubungula idatha yezinhlelo ze-AI ne-ML. Izixazululo ze-hardware ezisetshenziswa kuzo zinezinga eliphezulu lokuchithwa kwamandla. Ukuze zisebenze ngempumelelo, kwakudingeka umklamo omusha wama-racks.

Yini osekwaziwa nge-Open Rack v3

Abathuthukisi bayaqaphela ukuthi izinga elisha lizoguquguquka futhi liguquguquke kune-v2, futhi lizothatha konke okuhle kakhulu ezinguqulweni zangaphambilini - ukusebenza kahle kwamandla, i-modularity, ukubumbana. Ngokuqondene, eyaziwayoukuthi izoqhubeka nokusebenzisa amandla kagesi angu-48-volt.

Ukwakhiwa kwama-racks amasha kuzodinga ukuthuthukisa ukujikeleza komoya kanye nokukhipha ukushisa. Ngendlela, izinhlelo eziwuketshezi zizosetshenziselwa ukupholisa imishini. Amalungu e-OCP seziyasebenza ngezixazululo eziningana kule ndawo. Ikakhulukazi, amasekhethi okuxhumana oketshezi, izishintshi zokushisa ezifakwe kuma-rack, nezinhlelo zokucwilisa ziyathuthukiswa.

Okuthunyelwe

Imininingwane Onjiniyela isimangalo, okuzothi esikhathini esizayo i-Open Rack v3 izokwehlisa izindleko zezinhlelo ze-IT ezikhungweni zedatha. Kwa Schneider Electric kubaliweukuthi inguqulo yesibili yama-rack isivele yehlisa izindleko zokulungisa iseva ngo-25% uma kuqhathaniswa nemiklamo ye-rack yendabuko. Kunesizathu sokukholelwa ukuthi ukucaciswa okusha kuzothuthukisa lesi sibalo.

Phakathi kokushiyeka kwezinga, ochwepheshe aba ubunzima bokulungisa imishini namagumbi omshini ngokuvumelana nezidingo zawo. Kukhona okungenzeka ukuthi izindleko zokuvuselela amagumbi eseva zizodlula izinzuzo ezingaba khona kusukela ekusetshenzisweni kwawo. Ngalesi sizathu, i-Open Rack igxile kakhulu ezikhungweni zedatha ezintsha.

Okuningi kokubi hlanganisa izici zokuklama zesixazululo. Isakhiwo se-rack evulekile ayinikezi isivikelo othulini. Futhi, kwandisa amathuba okulimaza imishini noma izintambo.

Amaphrojekthi afanayo

NgoMashi, kwakhululwa enye imininingwane yama-racks - I-Open19 System Level (Landa ifayela le-PDF ukuze ubuke imininingwane). Lo mbhalo wakhiwe ku-Open19 Foundation, lapho kusukela ngo-2017 ngiyazama lungisa izindlela zokwenza izikhungo zedatha. Sixoxe kabanzi ngale nhlangano ku okunye kokuthunyelwe kwethu.

Izinga le-Open19 System Level lichaza isici sefomu lendawo yonke lama-rack futhi libeka izidingo zesakhiwo senethiwekhi nokusetshenziswa kwamandla. Ithimba le-Open19 liphakamisa ukusebenzisa lokho okubizwa ngokuthi amakheji ezitini. Zingamamojula anama-chassis amaningana lapho ungabeka khona i-hardware edingekayo - amaseva noma izinhlelo zokugcina - ngokuhlanganiswa okungahleliwe. Futhi ekwakhiweni kukhona amashalofu wamandla, ukushintshwa, ukushintshwa kwenethiwekhi kanye nesistimu yokuphatha ikhebula.

Ukupholisa, kusetshenziswa isistimu yokucwilisa. ukupholisa ketshezi amanzi omile aqonde ngqo ku-chip. Ababhali bemiqondo gubhaukuthi i-Architecture ye-Open19 ithuthukisa ukusebenza kahle kwamandla kwesikhungo sedatha kukonke ngo-10%.

Ochwepheshe bezimboni ze-IT bakholelwa ukuthi esikhathini esizayo, amaphrojekthi afana ne-Open19 ne-Open Rack azokwenza kube nokwenzeka ukwakha ngokushesha izikhungo zedatha eziguquguqukayo zokusebenza nezixazululo ze-IoT, zibe negalelo ekuthuthukisweni kobuchwepheshe be-5G kanye ne-peripheral computing.
