Ukukhetha i-Fiber Umkhopha kwezinto zakho Server Isidingo
A iswitchi se-fiber yilisebe esibalulekile kwi-infrastruktura ye-server, ekhuluma ngokulayisha idatha phakathi kwezisevisi, amagcino olawo, nezinhlobo zokuxhumana ngokusebenzisa amakhebula e-fiber-optic. Inikeza izigaba ezinkulu, izibele ezide, nezokuphila ngokungcono kunazo ezinye i-Ethernet switches, okwenza yinto esingakananiyo kuzo zikhombisi ezifanelekayo. Kodwa noma kukhona amatholakale amaningi, ungakhetha kanjani i-right iswitchi se-fiber ngokuthiwa yinto onayo? Ake sibheke ngokucacile amatholakale okukhetha, kusukela kuspeedu nezindlu ku-skalabiliti nezokuphila.
1. Qinisekisa i-Speed (Data Rate) Esiyidingekayo
Izishayeli zemifibha zenza ngokwezindleko ezahlukene, futhi ukukhetha okulungile kubangelwa ngelithi inca elikhona ledata lekweyisebenzela leserver.
- 1 Gbps (Gigabit) : Kufanele kwezindlela ezincane ezine-traffic edata encane, njengamadivazini amancane noma amakhaya. Ishayeli yemifibha ye-1 Gbps isebenza kakadelela kumisebenzi emibi: ukwabelana kwefile, imeyili yamaserver, noma ukuxhumeka kwezinkampani ezimbalwa kumaserver omkhulu.
- 10 Gbps : Indawo ephakeme kakhulu kwezomphakathi futhi kwezinkampani ezikhulu. Inquma letraffic ephakeme, njengekulandelana kwezinhlobo zedatha, ukusebenzisa kakhulu, noma ukulayisha idatha phakathi kweziserver. Ishayeli yemifibha ye-10 Gbps iyazi ukusebenza ngokugcwele noma lapho abasebenzisi abaningi bafike kumaserver ngasinye.
- 40 Gbps ne-100 Gbps : Yandwe ukwenziwa kwezinkampani ezikhulu noma kwezindawo zokugcina idatha. Lezi zishayeli zemifibha ezinezindleko eziphakeme zinquma ledata ephakeme, njengokusebenzisa kakhulu kwezinhlobo ezinhle, ukusebenzisa izinto ezikhoyo kumawebhu, noma ukusebenzisa idatha ngokushesha. Zifanele kwezinkampani ezineziserver ezingu-100 noma kwezilayini ezikhulu.
Ukuhlanganisa ubukhawulezwe be-fiber switch kuzindlela zakho zokusebenzisa idatha ukuvikela ukungena kwezindlela. I-switch eshiyekileyo yobukhawulezwe yobukhawuleza konke kwezinhleke, noma kube nezikhala eziphezulu kakhulu kungena amaphela kakhulu.
2. Bala inombolo yezithuba eziyadingekayo
Inombolo yezithuba eziyakhiwe kwi-fiber switch iba yinani lezilawuli (i-server, ukugcinwa, ezinye i-switches) ongayakha ngokwesibonelo.
- Izinyathelo ezincane (1–5 i-server) i-fiber switch enezithuba ezingama-8–16 iyafanele. Lokhu kuvumela ukukhipha i-server, isilawuli sokugcinwa, kunoma i-router ngekuthi kungena kakhulu.
- Izinyathelo ezijwayelekile (6–20 i-server) khetha izithuba ezingama-24–48. Lokhu kuvumela ukukhipha i-server eziningi, kunoma ukuxhumeka kwezinhlelo zokubamba kabusha noma izinhlelo eziphambene. Isibonelo, i-fiber switch enezithuba ezingama-48 ingaxhuma i-server ezi-20, izith storage drive ezi-10, nezith workstation ezi-18 ngokuhle.
- Izinyathelo ezikhulu (20+ i-server) khetha i-fiber switch enezithuba ezingama-48+, noma sebenzisa amakhala amabili asetile ngokulandelana. Ukusetshenziswa kuvumela ukukhipha amakhala ngokulandelana kwekuthi kungaba yisimo esisodwa, ukuphatha ngokwesibonelo futhi ukongeza inani eliphezulu lezithuba.
Faka phakathi kwama-ports angama-20-30% ekuhlukeni ukuthuthukiswa kwamanje. Isibonelo, uma uneedi ya-ports e20 manje, iswitch yefayibha enama-ports angama-24-32 iseba indawo ukufaka amaserver foma izinto eziningi emuva kanti.
3. Bheka Ukuthi Kuhlanganisa Nenethiwekhi Yakho
Isiwitshi sefayibha kufanele sisebenze ngendlela ethulwane nenethiwekhi yakho esikhundleni, kanye nezicabhu, amaserver kanye nezinhla yokugcina izinhloso.
-
Uhlobo lwefayibha (singil-mohla vs. multi-mohla) :
- Ifayibha ephakathi kwezindle: Isendula izicabhu eziphezulu, isebenza kizindle ezincane (kuya kuma-550 methe). Iyincane kakhulu foma isebenziswa kakhulu kizindle zokusebenza noma izinhlanzeli zethu enezicabhu eziphakathi kwezindle. Sicabangela ukuthi isiwitshi sefayibha yakho sisebenze nezindle zokusebenza uma izicabhu zakho zilula leyo.
- Ifayibha yomohla omnye: Isendula izicabhu ezincane, isithunyelwe izinhloso kizindle ezide (kuya kuma-10+ kilomethe). Iyisizo esihle ukuxhuma amaserver kuzindle ezahlukene noma izinhlanzeli ezikhulu. Khetha isiwitshi sefayibha onesuporta yomohla omnye ukuze usebenze kizindle ezide.
- Iziphrothokholi : Imiphiqo yonke ye-fiber iyavikela izimiso eziphambene ne-TCP/IP, kepha bheka uma unecala lezinye. Isibonelo, uma usebenzisa i-SAN (Izinhlelo Zokugcinwa Kwamathina) kugcinwa kwamathina, qinisekisa ukuthi imiphiqo ye-fiber iyavikela i-Fibre Channel (FC) noma i-FCoE (Fibre Channel over Ethernet).
- Ukuhlanganiswa Kwamathina Nezilawuli : Qinisekisa ukuthi izimpendulo zakho, izinhlelo zokugcinwa, nezinye iindlela zenkqubo enenxa yeziyindlwana (Izindawo ze-SFP noma SFP+) ezifanayo neleli mpheqo. Iziphanti ezingafani zingakuthiwa kuzindlela noma ukushisa okuphansi.
4. Thumela Okuphezulu Kwekulayishwa Kwamanye Amaqha
Isithuthi samathina sakudala kuzoba kuholela, ngakho le mpheqo ye-fiber kufanele kuthole ukuthi kuhole.
- Ukuhlanganiswa Okudonselwa : Imiphiqo ye-fiber ekuhlanganeni iyavumela ukuthi uhlangane nezinyai imiphiqo (kuya kwe-8-10) kwenye indlela, ibophelelwa ngumoya oyedwa. Lokhu kuncipha kakhulu kunokuthenga mpheqo enkulu emuva kanti kwenza ukuthola kuyindle. Isibonelo, ukuqala nampheqo engenxa ye-24 nokuwengeza enye engenxa ye-24 emuva kuneza amagenxa angu-48 noma kungabonakali ukuthola kabusha yonke indlela.
- Imodi yokuthiwa ngokuvula : Buka imishini yemeyili enezinhlobo ezingavuleki, lapho ungayengeza amaphoyinti noma uthole ukhula (isb., kusukela ku-10 Gbps ku-40 Gbps) ngokushintsha imodi. Lokhu kuthula ukuthi ubeke kabusha yonke imishini lapho izidingo zakho zilishwa.
- Ukuthuthwa kwezinhlobo ezingu-3 : Sicela imishini iyasebenza ngokuvulekile uma ungene amaserveri. Imishini yemeyili engcono kufanele inamandla wokusebenza oyanayo ukuphatha izinhlobo ezingu-2 fana nezin-3 kanye nezin-3 zezinhlobo zakho zasemukelweni, ukungena ngokulula kokuqhunyelwa kwamathimekhi ngenkathi kuthole ukuvula.
5. Velela Iziphawuli Zokuthembekile
Ukubekwa kwamaserveri kudinga ukuthi kungabi naliphi na isikhathi sokuthiwa, ngakho imishini yemeyili kufanele iyithembekelekele—noma lapho isebentelwa ngokugcwele.
- Imithomba yokudla engama-2 : Imishini yemeyili enemithomba yamandla eziyi-2 iyagcina ukuthi isebene uma enye ingelile. Lokhu kuyinkimbinkimbi kwezimali zasemzimbeni noma ezihospitalini, lapho isikhathi sokuthiwa singelisa amanani noma ukulahleka komsindo.
- Izinhlobo ezishintshwayo ngokusheshayo : Izicathami ezijikelezayo njengefan isiyo kanye nezinhlayiya zokuvula zokungena zisetshenziswa ngaphandle kokuvula ukuvula okuphazamise kwezinsuku. Uma ifan isiyo iyagelela, ungayishintshela ngenkathi iswithi iyasebenza.
- IMTBF ephezulu : IMTBF (Mean Time Between Failures) iyinhloko yokuqala (kamathora) ethathwa ngokuthi yiziphi izinsuku eswithi sizobeke sisebenza ngaphandle kwezinkinga. Sicabanga iswithi sefiber esine MTBF ye-100,000+ amathora - izinombolo ezincane zithi kunezinkinga eziningi.
- Ukulungisa amaphoyinti : Izinto ezijwayelekayo njenge-CRC (Cyclic Redundancy Check) zithola kanye nezilungisa iziphoso zedatha lapho datha ithunyelwa, ukuthi datha ethe kancane. Lokhu kuyakhi kakhulu kweziserver ezisebenzisa datha ebaluleke (isb., imali yokubhalwa noma amaphayili wobudleke).
6. Ccabanga kuMeneji kanye nezinsiza zokulandela
Iswithi sefiber esikhululwe ukusebenzela kakhulu kubasebenzi be-IT sibambisana nezinsuku, ngakho-ke lapho kusekelwe kakhulu.
- Isikhombimsebenzisi esisebenziseka kalula : Bheka amaswithi ane-dashboard ebhwebhini noma i-CLI (Command Line Interface) ukukhwekha ngokulula. Ikhompiyitha lewebhu iyakhi kakhulu kubasebenzisi ababili, noma i-CLI iyafisa kakhulu kubasebenzisi abakhubonisi.
- Ukuphatha Kwesikhatsi Esasihlaleni : Ukunakwa ukulandela nokwenza utshintsho kwe-switch kusuka kuphi na (ngokusebenzisa i-VPN noma i-cloud) kungcono kwezimali ezahlukene. Isibonelo, i-IT team ingakhipha inkinga yokuqhagamshelana esibhedlela esinye ngaphandle kokuba ekuhlaleni.
- Imiyolo yokucokwa : Iifiber switches efinye ingathumela imiyolo (ngokuthumela i-imeyili, i-SMS, noma izicathami zokugxila kwenkqubo) ngokuchaphazela ukuphakama, iipoti ezingena noma ukuncipha kwezimali. Lokhu kuvumela ukuba udinge izinkinga ngaphambi kokuba kwenze ukungabi nesikhathi.
- Ukuthambekwa nezicathami zokugxilwa kwenkqubo : Qinisekisa ukuba iswitch iyasebenza ngokuxhomekeke kwi-SNMP (Simple Network Management Protocol) okanye i-Zabbix, ezingcwalisa izibalo (umehluko, umoya, iimfazwe) esimbeni esinye. Lokhu kwenza ukulandela inkqubo yakho yonke kube yimali.
Imibuzo Evame Ukubuzwa
Yeyiphi into ehlukileyo phakathi kwe-fiber switch ne-Ethernet switch?
Ifiber switch isebenzisa iifiber-optic cables, ekunikeza amanqaku aphezulu (up to 100 Gbps+) nokude lula (km vs. meters for Ethernet). Ii-Ethernet switches zisebenzisa iicopper cables, ezingaphantsi kakhulu kodwa zimhlophe kwaye zinezwe lula.
Kungakanani i-ports engidinga yabo ukwenza umntu wezimali encinci?
Kumaqo angama-5 kuya kuma-10 namacala angama-20 kuya kuma-30: i-24 ports. Lokhu kubuyela indawo kwezinye izinto zokugcina, i-router, kunye nezinye okuzakhiwa ngemva koko.
Ngaba kufuneka ndichagge iswitshi le-fiber enye noma le-ndawo ephethwe?
Le-ndawo ephethwe yincinci kunye inasebenza kiziko elincinci (ifuyile enye). Le-ndawo enye ngapandle kweziko elide (phakathi kwezifuyi noma kwezikhala) kodwa iyincinci.
Ngaba ndidinga iswitshi se-fiber esibonakalayo?
Kuzizo zibalulekileyo (ezilala, iindawo zokugcina idatha), yebo. Iswitshi esibuyileyo simelela ukuba inethiwekhi iyasebenza xa leyo ekuqaleni ayisebenzi. Kwezindlu encinci, ukubonakala kungasingasingi.
Malini into yengqikithi engqokelelayo ye-swtich?
Izindleko ziya kuya kuma-$200 (1 Gbps, 8-port) kuya kuma-$5,000+ (100 Gbps, 48-port enobubanzi). Thatha inkqubo yakho ngokwesikhi, i-ports, kunye nezidingo zokubaluleka.
