I-InfiniBand yintsebenziswano ephezulu yokusebenza, injongo yokwenza intsebenziswano eninzi ngokusekelwe kwindlela yokucwangcisa intshukumo ebizwa ngokuthi "intsimbi yokuguqula." I-InfiniBand ("IB" ngcaciso emfutshane) yenzelwe ukusetyenziswa kwiisetyenziselwano ze-I / O ezinjengeinkcukacha zokugcina indawo (SAN) okanye kumanethiwekhi eqoqo. Liye libe yindlela ehamba phambili kwiikhomputha ezisebenzayo. Amanqaku angaphezu kwama-500 aphezulu kwihlabathi asebenzisa i-InfiniBand, ngaphezu kwe- Gigabit Ethernet .
Imbali ye-InfiniBand
Ukusebenza kwi-InfiniBand yaqala ngo-1990 phantsi kwamagama ahlukeneyo ngamaqela amabini ahlukeneyo amashishini adibanisa imigangatho yobugcisa kwinkqubo yokuhlangana. Emva kokuba amaqela amabini ahlanganiswe ngo-1999, "i-InfiniBand" ekugqibeleni yavela njengegama lwakhiwo olutsha. I-1.0 ye-InfiniBand Architecture standard yapapashwa ngo-2000.
I-InfiniBand isebenza njani
Iinkcukacha ze-InfiniBand Architecture layers 1 ukuya kwi-4 ye- OSI model . Ikhupha iimfuno zezinto eziphathekayo ze-hardware, kunye neendlela ezixhomekeke kuzo uxhumano kunye neendlela ezingenanto zokuthutha ezifana ne- TCP kunye ne- UDP . I-InfiniBand isebenzisa i- IPv6 yokujongana nokucwangciswa kwenethiwekhi.
I-InfinBand isebenza ngemisebenzi yokuthumela imiyalezo yezicelo ezibizwa ngokuba yi- I / O yesiteshi ezithatha iifayile zokusebenza kwenethiwekhi ukwenzela ukufezekiswa kwezinga eliphezulu kwiindawo ezizodwa. Inika amandla okwenza izicelo ezimbini ezincedisayo ze-Infiniband ukudala ishaneli esithethayo ngokuthumela nokufumana imigca ebizwa ngokuba yiPaue Peirs. Imephu yemigca kwiindawo zeememori ezifikeleleke kwisicelo ngasinye sokwabelana kwedatha (esibizwa ngokuba yi-Remote Direct Access Access okanye i-RDMA).
Inethiwekhi ye-InfiniBand inezixhobo ezine eziphambili:
- Gateway
- Iimodareli zeeSikethi zeMidlalo
- Abaphathi be-Subnet
- Tshintsha
Njengamanye amasango othungelwano , i-InfiniBand Gateway ibandakanya inethiwekhi ye-IB ngaphandle kwamanethiwekhi asekuhlaleni.
I-Adapter yeeSikethi zeHlabathi zidibanisa i-InfiniBand zixhobo kwi-IB, njengezinye iindidi zamasiko ezixhumo .
I- software ye- Subnet Manager ilawula ukuhamba kweendlela kwi-Intanethi ye-InfiniBand. Isixhobo ngasinye se-IB siqhuba ummeli we-Subnet Manager ukuba axhumane noMphathi oyiNtloko.
I-InfiniBand Switches yinto efunekayo yenethwekhi, ukwenzela ukuqokelela iifowuni ukuba zibambisane ngokudibanisa ezahlukeneyo. Ngokungafani ne-Ethernet kunye ne-Wi-Fi, amanethiwekhi e-IB awasebenziseli ii-routers .
Ukukhawuleza kangakanani kwi-InfiniBand?
I-InfiniBand isekela isantya se-intanethi ye-gigabit, ukuya kwi-56 Gbps nangaphezulu ngokuxhomekeke kwindlela yokucwangcisa kwayo. I-teknoloji yendlela ye-teknoloji ifaka inkxaso kwi-Gbps ezili-100 kunye nokukhawuleza ngokukhawuleza kwiinguqulelo ezizayo.
Imida ye-InfiniBand
Izicelo ze-InfiniBand zikuncitshiswe kumaqela angaphezu kwamagqabantshintshi kunye nezinye iinkqubo ezizodwa zenethiwekhi. Iimangalo zentengiso ngaphandle, i-InfiniBand ayilungiselelwe ukuxhunyezwa kwedatha yenkcazelo ngokubanzi ngendlela engathatha indawo ye-Ethernet okanye iFiber Channel kuma-datacenters ye-intanethi. Ayisebenzisi izikhokelo zentando yenethiwekhi yomdabu njengeTCP / IP ngenxa yokunciphisa ukusebenza kwale protocol, kodwa ngokwenza oko akuxhasi izicelo eziqhelekileyo.
Akukabikho iteknoloji engundoqo kwinqanaba kuba iilayibrari zeprogram zeprogram ezinjenge- WinSock zinakwenziwa ukuba zisebenze ne-InfiniBand ngaphandle kokubingelelwa ngenzuzo yokusebenza kwakhiwo.
