I-Mini SAS vs OCuLink vs MCIO, impendulo yakho iyini?
Esikhungweni sedatha sesimanje kanye nezinkambu zekhompyutha ezisebenzayo kakhulu, izixazululo ezintathu zokuxhumeka okusheshayo -Ikhebula le-Mini SAS SFF-8643, Ikhebula le-PCIE Oculink SFF 8611 4I, futhiIkhebula le-MCIO- bashintsha ukwakheka kokudluliselwa kwedatha phakathi kwamadivayisi. Nakuba lawa makhebula aklanywe kahle angase abukeke efana, aphethe imisebenzi ehlukene yephrothokholi futhi anikeza izinketho ezahlukene zokuxhumanisa ngesivinini esikhulu zamaseva, ama-array esitoreji, namadivayisi okusheshisa.
IIkhebula le-Mini SAS SFF-8643, njengesixazululo sokuxhumeka esivuthiwe, ibilokhu isetshenziswa ensimini yokugcina izinto iminyaka engaphezu kweshumi. Ekuqaleni yakhelwe iphrothokholi ye-SAS, isekela ukudluliswa kwedatha yeziteshi eziningi. Namuhla, i-Ikhebula le-Mini SAS SFF-8643isiphenduke isixhumi esibonakalayo se-multi-protocol, esikwazi ukuthwala amasignali e-PCIe ngaphezu kwezinhlelo zokusebenza zendabuko ze-SAS. Izinhlelo eziningi zokugcina ezisezingeni lebhizinisi zisathembele ku-Ikhebula le-Mini SAS SFF-8643s yokwandisa i-hard disk, ikhebula ngalinye linikeza i-bandwidth yesiteshi esisodwa efika ku-12Gb/s noma i-24Gb/s. Lapho belungiselela ama-array esitoreji, onjiniyela bavame ukusebenzisa izintambo eziningi ze-Mini SAS SFF-8643 ukuqinisekisa ukungasebenzi kahle kanye ne-bandwidth. Naphezu kokuncintisana okuvela ezindinganisweni ezintsha,Ikhebula le-Mini SAS SFF-8643iyaqhubeka nokudlala indima ebalulekile ezikhungweni eziningi zedatha ngenxa yokuzinza kwayo kanye nokuhambisana kwayo.
Ngokungafani ne-Ikhebula le-Mini SAS SFF-8643, iIkhebula le-PCIE Oculink SFF 8611 4Iiyisisombululo soxhumano esilungiselelwe iphrothokholi ye-PCI Express. LokhuIkhebula le-PCIE Oculink SFF 8611 4Iinomklamo omncane, okwenza ifaneleke kakhulu ekusetshenzisweni okuncishisiwe isikhala.Ikhebula le-PCIE Oculink SFF 8611 4Iiqukethe iziteshi ezine zesivinini esikhulu futhi isekela imininingwane ye-PCIe 3.0, 4.0, ngisho ne-5.0. Emkhakheni wekhompyutha esheshisiwe yi-GPU,Ikhebula le-PCIE Oculink SFF 8611 4Iivame ukusetshenziselwa ukuxhuma i-host kuma-accelerator angaphandle. Uma kuqhathaniswa nezixazululo zendabuko, i-Ikhebula le-PCIE Oculink SFF 8611 4Iinikeza ubuqotho besignali obuphezulu. Inani elikhulayo lamaseva e-AI liyawasebenzisaIzintambo ze-PCIE Oculink SFF 8611 4Iukwakha ama-topology asheshayo aguquguqukayo. Uma ukhethaIkhebula le-PCIE Oculink SFF 8611 4Is, onjiniyela kumele banake kakhulu ukuhambisana kwenguqulo, njengoba izintambo zezizukulwane ezahlukene ze-PCIe zingase zibe nomehluko wezimpawu zikagesi.
Njengesizukulwane sakamuva sezindinganiso zokuxhumanisa ezisheshayo,Ikhebula le-MCIOimelela ubuhlakani obubalulekile kubuchwepheshe bokuxhuma. Lokhu kumelela ubuhlakani obubalulekile kubuchwepheshe bokuxhuma.Ikhebula le-MCIOyamukela umklamo wokuxhumana onemigqa emibili, osekela ukudluliselwa kwesignali enobukhulu obuphezulu. Uma kuqhathaniswa nezimbili zangaphambilini,Ikhebula le-MCIOinganikeza iziteshi eziningi endaweni efanayo, okwenza ifaneleke kakhulu ezinhlelweni zokusebenza ze-bandwidth ephezulu. Amabhodi amaningi e-server esizukulwane esisha aseqalile ukuhlanganiswaIkhebula le-MCIOizixhumi zokuxhumana, ezithatha indawo yezixazululo zokuxhumeka zendabuko. Uma ufakaIkhebula le-MCIO, indlela yayo yokunamathisela eyingqayizivele idinga ukucatshangelwa ukuqinisekisa ukuxhumana okuthembekile. Ngokuthandwa kwe-PCIe 5.0 kanye ne-6.0, isabelo semakethe seIkhebula le-MCIOkulindeleke ukuthi ikhule ngokushesha. Abaphakeli bayathuthukaIkhebula le-MCIOubude obuhlukahlukene ukuze kuhlangatshezwane nezidingo zezakhiwo ezahlukene ze-rack. Izikhungo zedatha zesikhathi esizayo cishe zizosebenzisa kabanziIkhebula le-MCIOukwakha amanethiwekhi okuxhumana ngesivinini esikhulu.
Ekusetshenzisweni kwangempela, lezi zinhlobo ezintathu zezintambo zivame ukuhlangana ndawonye engqalasizinda efanayo. Isibonelo, iseva ye-AI ingasebenzisa i-Ikhebula le-PCIE Oculink SFF 8611 4Iukuxhuma ama-GPU,Ikhebula le-Mini SAS SFF-8643ukuxhuma isitoreji sendawo, kanyeIkhebula le-MCIOukuze kuxhunywe ngesivinini esikhulu ngaphakathi kwe-chassis. Onjiniyela kumele baqonde izici kanye nemikhawulo yohlobo ngalunye lwe-Ikhebula le-Mini SAS SFF-8643, Ikhebula le-PCIE Oculink SFF 8611 4I, kanye ne-MCIO Cable ukuklama ukwakheka kwesistimu okuhle kakhulu.
Ukukhetha okufaneleIkhebula le-Mini SAS SFF-8643, Ikhebula le-PCIE Oculink SFF 8611 4InomaIkhebula le-MCIOkudinga ukucabangela izici eziningi: izidingo zephrothokholi, izidingo ze-bandwidth, ibanga lokudlulisela, imikhawulo yesikhala, kanye nokucatshangelwa kwezindleko. Ngokuvamile, ukwanda kwesitoreji sendabuko kuvame ukukhethaIzintambo ezincane ze-SAS SFF-8643, ukuxhumana okuqondile kwamadivayisi e-PCIe kufanelekileIzintambo ze-PCIE Oculink SFF 8611 4I, kanye nezinhlelo zokusebenza ze-bandwidth ephezulu kakhulu ziya ngokuya zithandwa kakhuluAmakhebula e-MCIO.
Njengoba amazinga okudlulisa idatha eqhubeka ekhuphuka,Izintambo ezincane ze-SAS SFF-8643, Izintambo ze-PCIE Oculink SFF 8611 4I, futhiIkhebula le-MCIOzonke ziyashintsha. Izinguqulo zesikhathi esizayo zingase zisekele amaza aphezulu, ukusetshenziswa kwamandla okuphansi, kanye nemisebenzi yokuphatha enamandla. Kungakhathaliseki ukuthi ukhetha ini, ukufakwa nokugcinwa okufanele kwalezi zintambo ezinembile kubalulekile - kufaka phakathi irediyasi yokugoba efanele, ukukhululeka ekucindezelekeni, kanye nokuvikela ngogesi, okuthinta ngqo ukuzinza nokusebenza kwesistimu.
Ngomongo wokuvuselelwa kobuchwepheshe okusheshayo,Ikhebula le-Mini SAS SFF-8643s, Ikhebula le-PCIE Oculink SFF 8611 4Is, kanyeIkhebula le-MCIOAma-s akha i-trio yezixhumanisi ezisheshayo, ngayinye idlala indima ehlukile ezimweni ezithile zohlelo lokusebenza. Ukuqonda izici zobuchwepheshe kanye nemingcele yohlelo lokusebenza yalezi zintambo kubalulekile ekwakheni ingqalasizinda yesikhungo sedatha esebenza kahle futhi ethembekile.
