InfiniBand ndi makina opanga makina ambiri omwe amagwiritsidwa ntchito kwambiri pogwiritsa ntchito makina osinthira omwe amatchedwa "chosinthika." InfiniBand ("IB" mwachidule) inakonzedwa kuti igwiritsidwe ntchito m'maselo a I / O monga malo osungirako malo (SAN) kapena magulu a masango. Yakhala yowunikira kutsogolo pa kompyuta yamakono apamwamba. Ambiri opambana mazana asanu ndi awiri padziko lonse lapansi amagwiritsa ntchito InfiniBand, kuposa momwe amagwiritsa ntchito Gigabit Ethernet .
Mbiri ya InfiniBand
Ntchito ya InfiniBand inayamba mu zaka za m'ma 1990 pansi pa mayina osiyanasiyana ndi magulu awiri ogulitsa makampani omwe amapanga miyezo yowunikira machitidwe osiyanasiyana. Magulu awiriwa atagwirizanitsidwa mu 1999, "InfiniBand" pamapeto pake adatchedwa dzina la zomangamanga. Tsamba la 1.0 la Standard InfiniBand Architecture linafalitsidwa mu 2000.
Momwe Ntchito Imathandizira
Mafotokozedwe a InfiniBand Architecture magawo a 1 mpaka 4 a OSI chitsanzo . Zimaphatikizapo zofunikira zowonongeka za thupi ndi deta, komanso zimagwiritsa ntchito njira zoyendetsa zogwiritsa ntchito zogwirizana ndi TCP ndi UDP . InfiniBand imagwiritsa ntchito IPv6 poyang'ana pa makina ochezera.
InfinBand imagwiritsa ntchito mauthenga pa mauthenga omwe amatchedwa Channel I / O yomwe imawonjezera machitidwe opangira mauthenga kuti akwaniritse machitidwe apamwamba m'madera apadera. Zimapereka mwayi wothandizira awiri ogwira ntchito yotchedwa infiniband kuti apange njira yolankhulirana yolumikizana ndi kutumiza ndi kulandira mapepala omwe amalembedwa Mipukutu. Mapu a mapepala kumalo osungirako malingaliro omwe amawonekera pa ntchito iliyonse yogawa deta (yotchedwa Remote Direct Memory Access kapena RDMA).
Mndandanda wa InfiniBand uli ndi zigawo zikuluzikulu zinayi:
- Chipatala
- Makanema Adapters Channel
- Oyang'anira pa subnet
- Sintha
Monga njira zina zamagetsi , InfiniBand Gateway imalowetsa ma intaneti ndi mabungwe apakati.
Makanema Adapters Channel amagwirizana ndi InfiniBand zipangizo ku IB, monga mitundu yambiri yamakono a mapulogalamu .
Pulogalamu yamagetsi ya subnet imayendetsa magalimoto kuyenda pamtunda wa InfiniBand. Dongosolo lililonse la IB limayendetsa Wothandizira Mauthenga a Subnet kuti alankhule ndi Woyang'anira wamkulu.
InfiniBand Switches ndi chinthu chofunikira pa intaneti, kuti athe kugwiritsa ntchito zipangizo kuti aziphatikizana pazosiyana. Mosiyana ndi Ethernet ndi Wi-Fi, mabungwe a IB samagwiritsa ntchito maulendo .
Kodi Mwamsanga ndi InfiniBand?
InfiniBand imathandizira ma intaneti gigabit maulendo, mpaka 56 Gbps ndi apamwamba malingana ndi kukonzekera kwake. Mapulogalamu apakompyuta amaphatikizapo kuthandizira ma 100 Gbps ndi kuthamanga msanga m'zosinthidwa zamtsogolo.
Zofooka za InfiniBand
Mapulogalamu a InfiniBand amangokhala ochepa chabe pazinthu zamagulu ndi machitidwe ena apadera. Malonda amatsutsa, InfiniBand siinapangidwe kuti zitha kugwiritsira ntchito deta yolumikiza njira zomwe zingasinthe Ethernet kapena Fiber Channel pa intaneti. Sagwiritsira ntchito zida zamtundu wa protocol monga TCP / IP chifukwa cha kuchepa kwa machitidwe awa, koma pochita zimenezi sichikuthandizira machitidwe ambiri.
Sindinayambe kugwiritsa ntchito luso lamakono chifukwa makalata ovomerezeka a pulogalamu yamakono monga WinSock sangathe kugwira ntchito ndi InfiniBand popanda kupereka nsembe zopindulitsa za zomangamanga.
