Uyini Umehluko phakathi kwezintambo ze-DAC ne-AOC?

Namathisela Ikhebuli Eqondile,ebizwa nge-DAC. Ngamamojula we-transceiver ashintshwayo ashisayo afana ne-SFP+, QSFP, ne-QSFP28.

Ihlinzeka ngesixazululo esingabizi kakhulu, esine-high-density interconnects isixazululo se-high-speed interconnects kusuka ku-10G kuya ku-100G kuya kuma-transceivers e-fiber optics.

Uma kuqhathaniswa nama-transceivers optics, izintambo zokunamathisela eziqondile zinikeza isisombululo esingabizi kakhulu esisekela izivumelwano eziningi ezihlanganisa i-40GbE, 100GbE, Gigabit & 10G Ethernet, 8G FC, FCoE, ne-Infiniband.

Ikhebula le-Optical elisebenzayo, ebizwa nge-AOC.

I-AOC ngama-transceiver amabili axhunywe ndawonye ngentambo yefayibha, enza umhlangano onengxenye eyodwa. Njenge-DAC, i-Active Optical Cable ayikwazi ukuhlukaniswa.

Kodwa-ke, i-AOC ayisebenzisi izintambo zethusi kodwa izintambo zefiber ezivumela ukuthi zifinyelele amabanga amade.

AmaCable Optical Asebenzayo angafinyelela amabanga ukusuka kumamitha ama-3 ukuya kumamitha ayi-100, kepha avame ukusetshenziselwa ibanga elingafika kumamitha angama-30.

Ubuchwepheshe be-AOC benzelwe amanani amaningana wedatha, njenge-10G SFP+, 25G SFP28, 40G QSFP+, ne-100G QSFP28.

I-AOC iphinde ibe khona njengezintambo zokuphumula, lapho uhlangothi olulodwa lomhlangano luhlukaniswe lwaba izintambo ezine, ngayinye inqanyulwe yi-transceiver yezinga elincane ledatha, okuvumela ukuxhuma inombolo enkulu yamachweba namadivayisi.

Ezikhungweni Zedatha zanamuhla, umkhawulokudonsa owengeziwe uyadingeka ukuze kusekelwe ukusetshenziswa kwe-virtualization yeseva lapho imishini eminingi ebonakalayo ihlanganiswa kuseva eyodwa yokusingatha ngokomzimba. Ukuze kuhlangatshezwane nenani elikhula njalo lamasistimu okusebenza nezinhlelo zokusebenza ezihlala kumaseva angawodwana, ukwenziwa nge-virtual kudinga ukudluliswa kwedatha okwandiswe kakhulu phakathi kwamaseva namaswishi. Ngesikhathi esifanayo, inani nohlobo lwamadivayisi ahlala kunethiwekhi kukhulise ngokumangalisayo inani ledatha okudingeka idluliselwe futhi isuke kumanethiwekhi endawo yokulondoloza (ama-SAN) kanye Nesitoreji Esinamathiselwe Senethiwekhi (NAS). Uhlelo lokusebenza ikakhulukazi lwezinhlelo zokusebenza ze-I/O ezinesivinini esikhulu endaweni yokugcina, inethiwekhi, kanye nezimakethe zezokuxhumana, Amaswishi, amaseva, amarutha, amakhadi esixhumi esibonakalayo senethiwekhi (NICs), Ama-Adaptha Amabhasi Okusingatha (ama-HBA), kanye Nokuminyana Okuphezulu kanye Nokusebenzisa Idatha Ephezulu.

I-KCO Fiber inikeza i-AOC yekhwalithi ephezulu kanye nekhebuli ye-DAC, engasebenzisana ngo-100% nokushintsha okuningi komkhiqizo njenge-Cisco, HP, DELL, Finisar, H3C, Arista, Juniper, … Sicela uxhumane nethimba lethu labadayisi ukuze uthole ukwesekwa okungcono kakhulu mayelana nezindaba zobuchwepheshe kanye nenani.
