LAN ihinduranya na SAN ihindura, itandukaniro irihe?

LAN na SAN bihagaze kumurongo wibanze hamwe nububiko bwibibanza, kandi byombi nuburyo bwambere bwo guhuza imiyoboro ikoreshwa cyane muri iki gihe.

LAN ni ikusanyirizo rya mudasobwa hamwe na peripheri bisangiye itumanaho ryitumanaho cyangwa ridafite umugozi kuri seriveri iherereye mubice bitandukanye. Ku rundi ruhande, SAN mu muyoboro, itanga umurongo wihuse kandi igenewe imiyoboro yigenga, ituma imiyoboro idahwitse ya seriveri nyinshi hamwe n’ibikoresho bitandukanye bisangiwe.

Nkibyo, ibice bibiri byingenzi bikoreshwa murusobekerane rwa mudasobwa ni LAN ihinduranya na SAN. Nubwo LAN ihindura hamwe na SAN byombi ni inzira zombi zo gutumanaho amakuru, zifite itandukaniro, reka rero turebe neza hepfo.

1 Guhindura LAN ni iki?

Guhindura LAN ni uburyo bwo guhinduranya paki ikoreshwa mugukwirakwiza paki hagati ya mudasobwa kuri LAN murusobe rwakarere. Ubu buhanga bugira uruhare runini mugushushanya imiyoboro kandi birashobora kunoza imikorere ya LAN no kugabanya inzitizi zumurongo. Hariho ubwoko bune bwo guhinduranya LAN:

Guhindura byinshi;
Igice cya 4 guhinduranya;
Igice cya 3 guhinduranya;
Igice cya 2 guhinduranya.

Nigute LAN ihindura ikora?

LAN ihinduranya ni Ethernet ihindura ikora ishingiye kuri protokole ya IP kandi itanga uburyo bworoshye bwo guhuza hagati yabohereje nabakira binyuze mumurongo uhuza ibyambu nibihuza. Iyi gahunda ituma umubare munini wabakoresha ba nyuma basangira ibikoresho byurusobe. LAN ihindura ikora nka paki ihinduranya kandi irashobora gukemura icyarimwe amakuru icyarimwe. Ibyo babikora basuzuma aho berekeza kuri buri cyiciro cyamakuru hanyuma bagahita berekeza ku cyambu runaka kijyanye nigikoresho cyakiriwe.

Uruhare rwibanze rwa LAN ni ukuzuza ibikenewe byitsinda ryabakoresha kugirango bashobore guhuriza hamwe umutungo basangiye kandi bavugane nta nkomyi. Ukoresheje ubushobozi bwabahindura LAN, igice kinini cyurugendo rwurusobe rushobora kuba mubice bigereranijwe bya LAN. Iki gice kigabanya neza LAN muri rusange, bigatuma habaho ihererekanyamakuru ryoroshye no gukora urusobe.

2 SAN ihindura iki?

Ububiko bwibibanza Umuyoboro wa SAN guhinduranya nuburyo bwihariye bwo gukora imiyoboro hagati ya seriveri hamwe n’ibidendezi bisangiwe hagamijwe gusa korohereza ihererekanyamakuru ryerekeye ububiko.

Hamwe na SAN ihindura, birashoboka gukora imiyoboro minini, yihuta yo kubika imiyoboro ihuza seriveri nyinshi kandi ikagera ku makuru menshi, akenshi igera kuri petabytes. Mubikorwa byabo byibanze, SAN ihindura neza guhuza traffic hagati ya seriveri nibikoresho byabitswe mugusuzuma paki no kubayobora kumwanya wateganijwe mbere. Igihe kirenze, urusobe rwibibanza byahinduwe byahindutse kugirango bishyiremo ibintu byateye imbere nko kurenga inzira, gusuzuma imiyoboro, hamwe no kwihuta kwagutse.

Nigute Umuyoboro wa Fibre ukora?
Umuyoboro wa Fibre ni ikintu cyingenzi mubice byabitswe SAN ifasha kohereza amakuru neza hagati ya seriveri nibikoresho byabitswe. Ihindura ikora mugukora umuvuduko wihuse wigenga wagenewe kubika amakuru no kugarura.

Muri rusange, Umuyoboro wa Fibre uhinduranya ibyuma na software byihariye byo gucunga no kuyobora amakuru yimodoka. Ikoresha protocole ya Fibre, protocole ikomeye kandi yizewe itumanaho igenewe ibidukikije bya SAN. Nkuko amakuru yoherejwe kuva kuri seriveri kubikoresho byabitswe naho ubundi, bikubiye mumurongo wa Fibre, byemeza ubudakemwa bwamakuru no kohereza byihuse.

Guhindura SAN ikora nkumupolisi wumuhanda kandi ikagena inzira nziza yamakuru yo kunyura muri SAN. Irasuzuma inkomoko hamwe na aderesi ya Fibre Umuyoboro wa Fibre kugirango uyobore neza paki. Iyi nzira yubwenge igabanya ubukererwe nubucucike, byemeza ko amakuru agera aho yerekeza vuba kandi yizewe.

Byibanze, Umuyoboro wa Fibre uhindura gahunda yo gutembera kwamakuru muri SAN, ugahindura imikorere nubwizerwe mubidukikije byibanda cyane.

3 Bitandukaniye he?

Kugereranya LAN ihinduranya na SAN irashobora kandi gutekerezwa nko kugereranya SAN ihinduranya umuyoboro, cyangwa umuyoboro wa Fibre uhindura kuri Ethernet. Reka turebe itandukaniro nyamukuru riri hagati ya LAN na SAN.

Itandukaniro
LAN yahinduwe yabanje gukorerwa impeta ya token na FDDI hanyuma isimburwa na Ethernet. Guhindura LAN bigira uruhare runini mugutezimbere imikorere rusange ya LAN no gukemura neza ibibazo bihari. LAN irashobora guhuza bidasubirwaho ibikoresho bitandukanye nka seriveri ya dosiye, printer, ububiko bwububiko, desktop, nibindi, hamwe na LAN irashobora gucunga neza urujya n'uruza hagati yibi bice bitandukanye.

Kandi SAN ihinduranya yagenewe imiyoboro ikora cyane kugirango yizere kohereza-gutinda no gutakaza amakuru. Yateguwe neza kugirango acunge neza imitwaro iremereye, cyane cyane mumikorere ya Fibre ikora cyane. Yaba umuyoboro wa Ethernet cyangwa Fibre, ububiko bwibibanza byahinduwe byeguriwe kandi bigashyirwa mubikorwa kugirango bikore traffic traffic.

Itandukaniro ryimikorere
Mubisanzwe, LAN ihindura ikoresha umuringa na fibre kandi ikora kumurongo wa IP ishingiye kuri Ethernet. Igice cya 2 LAN guhinduranya itanga inyungu zo kohereza amakuru byihuse hamwe nubukererwe buke.

Nibyiza cyane mubiranga nka VoIP, QoS na raporo yumurongo. Igice cya 3 LAN ihindura itanga ibintu bisa nkibiyobora. Kubijyanye na Layeri 4 LAN Hindura, ni verisiyo yambere ya Layeri 3 LAN Hindura itanga izindi porogaramu nka Telnet na FTP. Byongeye kandi, LAN Switch ishyigikira protocole harimo ariko ntabwo igarukira kuri SNMP, DHCP, Apple Talk, TCP / IP.

SAN ihindura yubaka ku musingi wububiko bwa iSCSI, ikubiyemo umuyoboro wa Fibre hamwe nikoranabuhanga rya iSCSI. Ikintu cyingenzi cyingenzi nuko SAN ihindura itanga ubushobozi bwo kubika hejuru ya LAN. Umuyoboro wa Fibre urashobora kandi kuba Ethernet.

Byaba byiza, Ethernet ishingiye kuri SAN ihinduka yakwegurira gucunga traffic traffic murusobe rwububiko bwa IP, bityo bigatuma imikorere iteganijwe. Na none, muguhuza ibice bya SAN, hashobora gushyirwaho umuyoboro mugari wa SAN kugirango uhuze seriveri nyinshi nibyambu.

4 Nahitamo nte uburyo bwiza?

Iyo usuzumye LAN na SAN, guhitamo LAN ihinduka cyangwa SAN ihinduka cyane. Niba ibyo ukeneye birimo protocole yo kugabana dosiye nka IPX cyangwa AppleTalk, noneho IP ishingiye kuri IP ishingiye kuri IP niyo ihitamo neza kububiko. Ibinyuranye, niba ukeneye switch kugirango ushyigikire Fibre Umuyoboro ushingiye kububiko, birashoboka ko uhuza ububiko bwurusobe.

Guhindura LAN byorohereza itumanaho muri LAN muguhuza ibikoresho murusobe rumwe.

Ku rundi ruhande, umuyoboro wa fibre uhinduka, ukoreshwa cyane cyane muguhuza ibikoresho byo kubika na seriveri kugirango ubike neza kandi ushakishe amakuru. Ihinduranya riratandukanye mubiciro, ubunini, topologiya, umutekano, nubushobozi bwo kubika. Guhitamo hagati yabo biterwa nibisabwa byihariye byo gukoresha.

Guhindura LAN ntibihendutse kandi byoroshye kuboneza, mugihe SAN yahinduwe ihenze cyane kandi bisaba iboneza ryinshi.

Muri make, LAN ihinduranya na SAN ihinduranya ni ubwoko butandukanye bwo guhinduranya imiyoboro, buri kimwe kigira uruhare rwihariye murusobe.
