- Umehluko oyisisekelo phakathi kokushintsha okuphethwe nokungaphethwe ngokuya ngobunkimbinkimbi benethiwekhi.
- Ukuhlaziywa kwezindinganiso ze-10GBASE-T, SFP+ kanye ne-Multigigabit (NBASE-T).
- Izindlela zokukhetha ezisekelwe ekuminyaneni kwembobo, amandla okushintsha, kanye nokusebenza kahle kwamandla.
- Izincomo zehadiwe ezivela kumabhrendi ahamba phambili njengeNetgear, QNAP, D-Link, kanye ne-TP-Link.
Uma uke wazizwa sengathi inethiwekhi yakho yendawo iyasilela lapho uhambisa amafayela amakhulu noma uphatha imishini ebonakalayo, kungenzeka ukuthi ufinyelela imikhawulo yesivinini se-Gigabit sendabuko. Ezweni lanamuhla, lapho ukulungiswa kwe-4K, amadivayisi e-NAS asebenza kahle kakhulu, kanye ne-Wi-Fi 7 kuyinto evamile, ukuthuthukela ku- Iswishi ye-Gigabit eyi-10 (10GbE) Akuyona nje into efiselekayo kubathandi, kodwa kuyisidingo sokugwema labo abacasulayo amabhodlela ezivimbela ukukhiqiza.
Ukungena emkhakheni we-10 Gbps kungabonakala sengathi kuyi-labyrinth ngenxa yenani elikhulu lama-acronym kanye nezincazelo zobuchwepheshe. Kusukela ku-copper yakudala kuya ku-fiber optics, kanye nokufaka izinketho ze-hybrid, ukukhetha ihadiwe efanele kuhilela ukuqonda hhayi isivinini kuphela, kodwa futhi indlela ithrafikhi ephathwa ngayo Futhi kuzoba namuphi umthelela ekusetshenzisweni kukagesi ehhovisi lakho noma ekhaya lakho? Sizohlaziya kahle konke okudingeka ukwazi ukuze uthenge kahle.
Imiqondo eyisisekelo: Iyini ngempela iswishi ye-10GbE?
Kalula nje, sikhuluma ngedivayisi exhumanisa imishini kunethiwekhi yendawo, evumela idatha ukuthi igeleze ngesivinini esiphezulu sama-gigabits ayi-10 ngomzuzwana. Ngokungafani nezishintshi ezijwayelekile, la madivayisi asebenzisa i- umthamo omkhulu wokushintsha ukuze ukuxhumana phakathi kwamaseva noma izindawo zokusebenza kube ngokuphazima kweso, kunciphisa ukubambezeleka okuncane.
Ukuze lokhu kusebenze, iswishi kumele ikwazi ukuphatha ukugeleza kwamaphakethe ngaphandle kokuletha ukubambezeleka. Lokhu kubalulekile ezindaweni i-high performance computing (HPC) noma amaqoqo e-Beowulf, lapho ama-node kumele ashintshanise ulwazi ngesivinini esikhulu ukuze uhlelo lwefayela, njenge-NFS, lungabi yindawo ebuthakathaka yokwakheka.
Uma siqhathanisa i-Gigabit Ethernet (1GbE) ne-10G, umehluko mkhulu kakhulu. Akukhona nje ukuthi ishesha ngokuphindwe kayishumi, kodwa futhi ivumela i- ukukhuliswa okubushelelezi kakhuluNakuba ukushintsha kwe-1G kushibhile futhi kwanele ukuphequlula noma ukusebenzisa i-Office, ukushintsha kwe-10G kuyinjini edingekayo ekuhleleni ividiyo yobungcweti, ukuhlaziywa kwe-Big Data, kanye nokwenza i-virtualization ibe nkulu.
Ukuphathwa Kwenethiwekhi: Kuphethwe Noma Kuxhunywe Ku-Plug-and-Play?
Lona umbuzo wokuqala omkhulu lapho uthenga. amaswishi angalawulwa Ziyindlela elula kakhulu: zixhume futhi ziyasebenza. Zilungele amanethiwekhi amancane lapho ungafuni khona ubunzima bokuhlela noma yini. Imikhiqizo efana ne-TP-Link ne-Netgear inikeza amamodeli ancintisana kakhulu kulesi sigaba, afanele labo abafuna ukusebenza okuluhlaza ngaphandle kwezinkinga zobuchwepheshe.
Ngakolunye uhlangothi, ukushintsha okulawulekayo (Okuhlakaniphile noma Okuphethwe Ngokugcwele) Lawa amadivayisi akuvumela ngempela ukuthi uthuthukise inethiwekhi. Anikeza imisebenzi ye-Layer 2 kanye ne-Layer 3 eyigugu kumphathi. Ungenza i- Ukucushwa kwe-VLAN ukuze kuhlukaniswe ithrafikhi (isibonelo, hlukanisa inethiwekhi yezivakashi kunethiwekhi yeseva), lungiselela i-QoS ukuze ibeke phambili izwi kune-IP futhi iqaphe isimo sembobo ngayinye usebenzisa i-SNMP noma izixhumi zewebhu.
Phakathi kwezinketho ezilawulekayo, sithola "ezihlakaniphile", eziyindawo ephakathi nendawo. Zinikeza imisebenzi eyisisekelo efana... ukuhlanganisa isixhumanisi kanye nokulawulwa kwesiphepho, kodwa ngokulungiselelwa okunembile kakhulu nokulula kunezinkinobho eziyinhloko ezenzelwe izikhungo ezinkulu zedatha.
Ubuchwepheshe bokuxhuma: Ithusi, I-Fiber kanye ne-Multigigabit
Akuwona wonke amachweba e-10G adalwe ngokulinganayo. Ubuchwepheshe I-10GBASE-T Isebenzisa izintambo zenethiwekhi ze-RJ-45 ezijwayelekile. Ukuze uyisebenzise, kuzodingeka wazi ukuthi umehluko phakathi kwezintambo ze-Cat6a noma ngaphezuluNakuba i-Cat 6 ingasebenza amabanga amafushane (ngaphansi kwamamitha angu-45), iyindlela elula kakhulu ngoba iyahambisana nalokho osunakho kakade ekhaya.
Uma ufuna ukusebenza okuphezulu kanye nokusetshenziswa kwamandla okuphansi, ama-port I-SFP+ Ziyisihluthulelo. Lezi zivumela ukusetshenziswa kwezintambo ze-fiber optic noma ze-DAC (Direct Attach Copper), okuyizintambo ezimfushane ezenzelwe ukuxhuma amaseva ku-rack efanayo nge-latency encane. Amaswishi amaningi anamuhla ahambisana amachweba ahlanganisiweokukuvumela ukuthi ukhethe phakathi kwe-RJ-45 noma i-SFP+ kuye ngokuthi yini oyidingayo nganoma yisiphi isikhathi.
Umkhuba onamandla kakhulu uyindinganiso I-NBASE-T noma i-MultigigabitLezi zishintshi azigxili ngqo kusuka ku-1G ziye ku-10G, kodwa kunalokho zisekela isivinini esiphakathi esingu-2.5Gbps kanye no-5Gbps. Lokhu kubalulekile ukuze kuzuzwe ngokugcwele amanethiwekhi e-Wi-Fi asheshayo 6 kanye no-7, ezidlula umgoqo we-Gigabit kodwa ezingafinyeleli ku-10G, ngaleyo ndlela zivimbele ikhebula ekubeni yimbangela yenkinga.
Ukuhlaziywa kwehadiwe kanye nezincomo zomkhiqizo
Uma ufuna into engabizi futhi eqinile, Netgear Ine-series ye-XS708T, i-smart switch elinganiselayo kahle yamabhizinisi amancane naphakathi. Ngakolunye uhlangothi, uma udinga ukuguquguquka okukhulu, QNAP Imangaze ngamamodeli ayo omndeni we-QSW, amanye awo ahlanganisa ngisho namakhono eseva ye-NAS kanye nokuphathwa kwamandla okuthuthukisiwe, okuvumela ukuguquguquka okumangalisayo ekuxubeni kwamachweba ethusi ne-fiber.
Uma ufuna isabelomali esiqinile noma udinga i-desktop ethile, TP-Link Inikeza i-TL-SX105, imodeli encane, exhumanisayo nedlalwayo efanelekela kahle ukuxhumanisa iziteshi ezimbili zokusebenza ezinamandla. Engxenyeni yokuphatha yobungcweti, D-Link Ivelele ngochungechunge lwayo lwe-DXS, oluvumela i- ukuhlaziywa okuningiliziwe kwemishini yenethiwekhi kanye nomzila we-L3 ongaguquki ukuze kuthuthukiswe ukuxhumana phakathi kwama-VLAN.
Uma ukhetha, ungakhohlwa ukubheka ukupholisa imishiniAmaswishi e-10G ayashisa kakhulu. Uma uzowabeka egumbini lokuphumula, funa amamodeli angenalutho (ngaphandle kwefeni) ukugwema imisindo ecasulayo, yize lokhu kusho ukuthi idivayisi kumele ibe sendaweni enomoya omuhle ukuze igweme ukwehla kwezinga lokushisa.
Ukufakwa kanye nokwenza ngcono ukusebenza
Ukusetha iswishi ye-10G akukhona nje ukuxhuma izintambo. Uma usebenzisa i-rack, qiniseka ukuthi ushiya isikhala esanele sokugeleza komoya. Kumamodeli angenawo umoya, kunconywa ukugcina i- ibanga okungenani libe ngu-2 cm uzungeze i-chassis ukuze ukushabalalisa ukushisa okungenamsebenzi kukwazi ukwenza umsebenzi wawo kahle.
Ukuze uthole okuningi ngehadiwe, kubalulekile ukuhlela I-IGMP Ukusnuza Uma unezinsizakalo ze-IPTV noma ithrafikhi yokusakaza okuningi, lokhu kuvimbela inethiwekhi ukuthi ingaphumeleli ngokuthumela idatha kuzo zonke izimbobo lapho eyodwa kuphela eyidingayo. Ngokufanayo, ukusetshenziswa kwe Amafreyimu weJumbo (amafreyimu edatha amakhulu) angathuthukisa kakhulu ukusebenza kahle ekudlulisweni kwamafayela amakhulu phakathi kwamaseva ne-NAS.
Ungalishayi indiva ikhwalithi yekhebula. Ukusebenzisa ikhebula elidala echwebeni le-10G kungabangela ukulahleka kwephakethe noma isivinini sixoxiswane ngokuzenzakalelayo ku-1G, okukushiya unehadiwe ebizayo esebenza njengehadiwe eshibhile. isitifiketi sekhebula Kungumshwalense wokuphila wokutshalwa kwezimali kwenethiwekhi yakho.
Ukukhetha iswishi ye-10GbE kuncike ngokuphelele ekutheni ubeka phambili yini ubulula besistimu yokuxhuma nokudlala noma amandla endawo ephathwayo enama-VLAN nama-QoS. Ngenkathi amamodeli e-multigigabit enikeza indawo ephakathi nendawo engabizi kakhulu, ukushintshana ngamachweba e-SFP+ kanye ne-10GBASE-T kuqinisekisa ukuthi ingqalasizinda yakho ingasekela ukukhula kwedatha eminyakeni eyishumi ezayo ngokuqeda ukubambezeleka nokuvumela ukugeleza kwedatha okusheshayo phakathi kwamaseva nezindawo zokusebenza.
