Yintoni umahluko phakathi kweentambo ze-DAC kunye ne-AOC?

Qhoboshela intambo ngqo,ebizwa ngokuba yi-DAC. Ngeemodyuli ze-transceiver ezitshintshatshintshayo ezishushu ezifana ne-SFP+, QSFP, kunye ne-QSFP28.

Ibonelela ngesisombululo se-interconnects esingabizi kakhulu nesinoxinano olukhulu kwii-interconnects ezikhawulezayo ukusuka kwi-10G ukuya kwi-100G ukuya kwii-transceivers ze-fiber optics.

Xa kuthelekiswa nee-transceivers ze-optics, iintambo ezincamathisela ngqo zibonelela ngesisombululo esingabizi kakhulu esixhasa iiprotokholi ezininzi eziquka i-40GbE, i-100GbE, i-Gigabit kunye ne-10G Ethernet, i-8G FC, i-FCoE, kunye ne-Infiniband.

Intambo ye-Optical esebenzayo, ebizwa ngokuba yi-AOC.

I-AOC zii-transceivers ezimbini ezidityaniswe kunye ngentambo yefayibha, nto leyo eyenza indibano enenxalenye enye. Njenge-DAC, i-Active Optical Cable ayinakwahlulwa.

Nangona kunjalo, i-AOC ayisebenzisi iintambo zobhedu kodwa iintambo zefayibha ezivumela ukuba zifikelele kumgama omde.

Iintambo ze-Active Optical zinokufikelela kumgama ukusuka kwiimitha ezi-3 ukuya kwi-100, kodwa zihlala zisetyenziswa kumgama ofikelela kwiimitha ezingama-30.

Itekhnoloji ye-AOC iye yaphuhliswa kwiindleko ezahlukeneyo zedatha, ezifana ne-10G SFP+, 25G SFP28, 40G QSFP+, kunye ne-100G QSFP28.

I-AOC ikwakho njengeentambo eziphumayo, apho icala elinye lendibano lahlulwe laba ziintambo ezine, nganye iphela ngesixhobo sokudlulisa idatha esincinci, okuvumela ukuqhagamshela inani elikhulu leeports kunye nezixhobo.

KwiZiko leDatha lanamhlanje, kufuneka i-bandwidth engaphezulu ukuxhasa ukusetyenziswa kwe-server virtualization apho oomatshini abaninzi be-virtual badityaniswe khona kwiseva enye ye-host ebonakalayo. Ukuze kuhlangatyezwane nenani elikhulayo leenkqubo zokusebenza kunye nezicelo ezihlala kwiiseva nganye, i-virtualization ifuna ukudluliselwa kwedatha okwandisiweyo kakhulu phakathi kweeseva kunye neeswitshi. Kwangaxeshanye, ubungakanani kunye nohlobo lwezixhobo ezihlala kwinethiwekhi zinyuse kakhulu inani ledatha ekufuneka idluliselwe kwiinethiwekhi zendawo yokugcina (ii-SAN) kunye ne-Network Attached Storage (i-NAS). Olu setyenziso lusetyenziswa kakhulu kwizicelo ze-I/O ezikhawulezayo kwiimarike zokugcina, zothungelwano, kunye neze-telecom, iiSwitshi, iiseva, ii-routers, amakhadi e-network interface (ii-NIC), ii-Host Bus Adapters (ii-HBA), kunye ne-High Density kunye ne-High Data Throughput.

I-KCO Fiber ibonelela nge-AOC kunye ne-DAC Cable ekumgangatho ophezulu, enokuhambelana ngokupheleleyo ne-100% noninzi lwee-brand switch ezifana neCisco, HP, DELL, Finisar, H3C, Arista, Juniper, … Nceda unxibelelane neqela lethu lezentengiso ukuze ufumane inkxaso engcono malunga nemiba yobugcisa kunye nexabiso.
