InfiniBand ke setsebi se holimo-ts'ebetso, se nang le mekhoa e mengata ea meralo ea marang-rang e itšetlehileng ka mochine oa lifofane o atisang ho bitsoa "switched fabric". InfiniBand ("IB" ka nako e khutšoanyane) e ne e etselitsoe hore e sebelisoe meketeng ea I / O e kang ho boloka sebaka sa marang-rang (SAN) kapa marang-rang a lihlopha. E fetohile molao-motheo o ts'oanang oa k'homphieutha e sebetsang hantle. Baholo-holo ba fetang 500 ba fetang ka ho fetisisa ba lefatše ba 500 ba sebelisa InfiniBand, ho feta ho sebelisa Gigabit Ethernet .
Histori ea InfiniBand
Ho sebetsa ho InfiniBand ho qalile lilemong tsa bo-1990 tlas'a mabitso a fapaneng ka lihlopha tse peli tse ikemetseng tsa indasteri tse thehiloeng litekanyetso tsa lisebelisoa tsa mekhoa ea tsamaiso. Ka mor'a hore lihlopha tsena tse peli li kopane ka 1999, "InfiniBand" qetellong e ile ea e-ba lebitso la mohaho o mocha. Version 1.0 ea Standard standard ea InfiniBand Architecture e phatlalalitsoe ka 2000.
How InfiniBand Works
Lintlha tse khethehileng bakeng sa likaroloana tsa InfiniBand Architecture tsa 1 ho isa ho tse 4 tsa mokhoa oa OSI . E akaretsa litlhoko tsa lisebelisoa tsa 'mele le tsa data-link, hape e na le li-protocols tse tsamaisanang le ho tsamaisana le ho se tsamaisane le TCP le UDP . InfiniBand e sebelisa IPv6 bakeng sa ho sebetsana le mocheso oa marang-rang.
InfinBand lisebelisoa tsa tšebeletso ea melaetsa bakeng sa likopo tse bitsoang " I-O-Channel" tse fetisang mekhoa ea ts'ebetso ea marang-rang e le ho finyella ts'ebetso e phahameng libakeng tse khethehileng. E fana ka bokhoni ba lik'hamphani tse peli tsa Infiniband tse khonang ho theha mocha o buisanang oa ho romella le ho amohela marulelo a bitsoang Mehla ea Lihlopha. Lebala la lihlopha tsa marang-rang ho libaka tsa mohopolo tse fumanehang ho e mong le e mong oa kopo ea ho arolelana lekunutu (e bitsoang Remote Direct Memory Access kapa RDMA).
Inthanete ea InfiniBand e na le likaroloana tse 'nè tse ka sehloohong:
- Seterata
- Li-Adapter tsa Channel Channel
- Baokameli ba Subnet
- E fetoha
Joaloka mekhoa e meng ea marang-rang , InfiniBand Gateway e kenyeletsa marangrang a IB ho marang-rang a sebakeng seo.
Li-Adapter tsa Channel Channel li kopanya liphahlo tsa InfiniBand ho lesela la IB, joaloka mefuta e meng ea setso ea li -adapter tsa marang-rang .
Software ea Manager ea Subnet e tsamaisa sephethephethe ho InfiniBand network. Mong le e mong mochine oa IB o tsamaisa Moemeli oa Mookameli oa Subnet ho buisana le Mookameli oa Bohareng.
InfiniBand Switches ke ntho e hlokehang ea marang-rang, ho etsa hore pokello ea lisebelisoa e khone ho nyalana ka likarolo tse fapaneng. Ho fapana le Ethernet le Wi-Fi, marang-rang a IB ha a sebelise li-routers .
How Fast is InfiniBand?
InfiniBand e tšehetsa maqhubu a li-gigabit a mangata, ho fihlela ho 56 Gbps le ho ea holimo ho latela mokhoa oa eona. Tsela ea theknoloji e kenyelletsa ts'ehetso ea 100 Gbps le e lebelo ka potlako liphetolelong tse tlang.
Meeli ea InfiniBand
Lik'homphieutha tsa InfiniBand li 'nile tsa fokotseha feela ho li-supercomputers tsa lihlopha le mekhoa e meng ea marang-rang e khethehileng. Khoebo e bolela ntle ho moo, InfiniBand e sa etsoa bakeng sa ho etsa marang-rang a ho etsa lits'ebeletso tsa ho etsa lits'ebetso ka mokhoa o ka nkeloang sebaka ka Ethernet kapa Fiber Channel ho Internet datacenters. Ha e sebelise mekhoa e tloaelehileng ea marang-rang ea protocol joaloka TCP / IP ka lebaka la meeli ea ts'ebetso ea li-protocol, empa ha e etsa joalo ha e tšehetse mekhoa e tloaelehileng.
Ha e e-s'o fetohe theknoloji e tloaelehileng kahobane karolo e tloaelehileng ea li-library tsa software tse kang WinSock e ke ke ea etsoa ho sebetsa le InfiniBand ntle le ho nyehela melemo ea ts'ebetso ea mohaho.
