Isixazululo Sesikhungo Sedatha

Isistimu yezintambo zegumbi lesikhungo sedatha yakhiwe izingxenye ezimbili: isistimu yezintambo zenethiwekhi ye-SAN kanye nesistimu yezintambo zenethiwekhi.Ebunjiniyela bezinhlelo zamakhompiyutha, kufanele bahloniphe igumbi elingaphakathi kwezintambo zokuhlela nokuklama okuhlangene, umzila webhuloho lezintambo kufanele uhlanganiswe ekamelweni lenjini kanye nezinye izinhlobo zamapayipi, ibhuloho, ukuze kuqinisekiswe ukuqaliswa kokusetshenziswa kohlelo kunengqondo futhi kuhlelekile. .Ubunjiniyela bekhebula besikhungo sedatha obunokuvumelana nezimo, ukunwebeka ukuze kuzuzwe ukuphathwa kwezintambo okungafuneki, lonke uhlelo lwekhebula oluhlelekile kufanele lube yisixazululo esiphelele sokugwema ukuvela kwephuzu elilodwa lokwehluleka.

Kwamukelwe: ipulaki nokudlala, ukuminyana okuphezulu, ukunwebeka, izixazululo zesistimu yekhebula enqanyuliwe, ukuphathwa kwesistimu ye-modular kanye nokuhlanganisa ngaphambi kokunqanyulwa kunganciphisa isikhathi sokufaka, kubone inethiwekhi yefiber yesikhungo sedatha ihamba ngokushesha, yengeze futhi ishintshe.uhlelo lungasetshenziswa emikhiqizweni eminingi ye-fiber optical ingasetshenziswa ekulahlekeni okuphansi kwesixhumi se-fiber optical kanye ne-fiber e-goba engazweli (i-bending radius 7.5mm), ukuze kuzuzwe i-backbone optical fiber attenuation kanye nokusebenza kokugoba.

Ama-fiber jumpers asetshenziselwa ukusebenzisa ukuxhumana noma ukuxhumanisa图片1

kukhebula ehleliwe, evame ukusetshenziswa ngokuhambisana namamojula okubona esikhungweni sedatha ukuze kuzuzwe ukuxhumana phakathi kwamadivayisi.
Isixazululo ku-10G optical module interconnection
Manje, izikhungo eziningi zedatha zisasetshenziswa i-10G Ethernet, futhi ukuthuthukiswa kwe-module optical kusuka ku-module enkulu ye-XFP optical kancane kancane ithuthukiswe ibe yi-module yamanje ye-SFP + optical module.Ichweba le-SFP+ optical module liyi-duplex LC interface, ngaleyo ndlela i-SFP+ optical module ingafinyelela ukuxhumana nge-duplex LC fiber optic jumper yokushintsha okubili, ama-routers, amaseva noma amakhadi esixhumi esibonakalayo senethiwekhi.Sihlinzeka ngekhwalithi ephezulu ye-duplex LC fibre optic jumpers, ikhebula le-optical liyatholakala ngemodi eyodwa kanye nemodi eminingi esebenza endaweni ehlukahlukene yokuxhumana kwenethiwekhi ye-10G.

Isixazululo ku-40G optical module interconnection
Ngemuva kweminyaka eminingana yentuthuko, i-40G Ethernet manje isishanela umhlaba, 40I-G QSFP + imojuli ye-optical isiphenduke inkanyezi ekhulayo yemakethe yemojula yokubona.Ngokungafani ne-10G SFP+ optical module, imbobo ye-40G QSFP+ optical module ikakhulukazi i-MPO/MTP interface edinga i-MPO/MTP fiber optic jumper ukuze kuzuzwe ukuxhumana.Sihlinzeka nge-single/multi-mode MPO/MTP fibre optic jumper, uhlobo lwejazi lutholakala ku-PVC, LSZH, OFNP njll. Ngaphezu kwalokho, siphinde sinikeze ibhokisi lokusabalalisa le-MPO/MTP ukukusiza ukuthi uthuthukele kalula kunethiwekhi ye-40G/100G.

Qaphela: uxhumano olude phakathi kwamamojula we-40G QSFP + optical ngokuvamile asebenzisa i-fiber yemodi eyodwa, ngaleyo ndlela i-40G QSFP + imojuli ye-optical kuhlelo lokusebenza lokudlulisa ibanga elide i-duplex LC interface ukuze ibone ukuxhumana nokusetshenziswa kwe-duplex LC single mode fibre optic jumper. .Nokho, i-40GBASE-PLRL4 QSFP+ imojula yokubona ivame ukusetshenziswa ne-12-core MPO/MTP single mode fibre optic jumper.
Njengoba sazi, imbobo eyodwa ye-40G QSFP+ (4 x 10 Gbps) ingalungiselelwa kuziteshi ze-fiber ezingu-4 x SFP+, ngakho-ke singasebenzisa i-MPO/MTP-LC fiber optic jumper ukuze sixhume kalula ku-10G kanye nemishini yenethiwekhi ye-40G.

Isixazululo ku-100G optical module interconnection
I-2016 ingashiwo ukuthi iyingqopha-mlando ku-100G Ethernet, kulo nyaka, i-CXP, i-CFP, i-CFP2, i-CFP4, i-QSFP28 namanye amamojula we-100G optical avela ngokungapheli emakethe.Njengomphakeli ochwepheshe, Inkampani Yethu nayo inganikeza lezi zixazululo zokuxhumanisa ezilandelayo ze-100G:

Ukuxhumana phakathi kwe-CFP/CFP optical modules
I-24-core MPO/MTP i-fiber optic jumper ehlinzekwe yi-RAISEFIBER iyisixazululo esifanele ekuxhumaneni phakathi kwamamojula okusebenza we-CXP/CFP, umdwebo ongezansi ubonisa uhlelo lokuxhuma olunemininingwane:

Ukuxhumana phakathi kwe-QSFP28 optical modules
Isimiso sokusebenza se-QSFP28 optical module sifana ne-40G QSFP +'s, kodwa umehluko wukuthi izinga lokudlulisela lesiteshi ngasinye se-fiber optic se-QSFP28 module optical yi-25Gbps, izinga lokudlulisela iziteshi ezine ze-fiber zingafinyelela ku-100G.I-12-core MPO/MTP i-fiber optic jumper iyadingeka ukuze kuzuzwe isixhumanisi se-fiber optic yemodi eminingi ye-QSFP28, futhi i-duplex LC yemodi eyodwa ye-fiber optic jumper iyadingeka ukuze kuzuzwe isixhumanisi se-fiber optic yemodi eyodwa ye-QSFP28 (sebenzisa i-100GBASE-LR4 QSFP28 module optical) .

Ukuxhumana phakathi kwe-CXP/CFP ne-10G SFP+ module optical
Ngenxa ye-CXP/CFP optical module isebenzisa iziteshi ze-fiber optic eziyi-10 x 10Gbps ukuze ibone ukudluliswa kwe-100G, ngakho-ke singasebenzisa i-MPO/MTP (24-core) LC fiber optic jumper ukuxhuma ku-CXP/CFP kanye ne-10G SFP+ module optical ukuze sisebenzise uxhumano. phakathi kwe-100G kanye ne-10G imishini yenethiwekhi.
