LAN na SAN bisobanuye Local Area Network na Storage Area Network, uko bikurikirana, kandi byombi ni byo buryo bw'ibanze bwo kubika amakuru bukoreshwa cyane muri iki gihe.
LAN ni uruhurirane rwa mudasobwa n'ibikoresho byo mu itumanaho bifitanye isano n'itumanaho rikoresha insinga cyangwa umugozi kuri seriveri ziri mu turere dutandukanye tw'isi. SAN mu muyoboro, ku rundi ruhande, itanga uburyo bwo guhuza bwihuta kandi yagenewe imiyoboro yihariye, ituma seriveri nyinshi zihuzwa neza n'ibikoresho bitandukanye byo kubika amakuru.
Bityo rero, ibice bibiri by'ingenzi bikoreshwa mu buryo buhuza umuyoboro wa mudasobwa ni swichi za LAN na swichi za SAN. Nubwo swichi za LAN na swichi za SAN byombi ari imiyoboro yo gutumanaho amakuru, bifite itandukaniro, reka turebere hamwe hano hasi.
1 Guhindura LAN ni iki?
Guhindura LAN ni uburyo bwo guhindura paki bukoreshwa mu kohereza paki hagati ya mudasobwa kuri LAN mu muyoboro w’aho uherereye. Ubu buryo bugira uruhare runini mu gushushanya umuyoboro kandi bushobora kunoza cyane imikorere ya LAN no kugabanya imbogamizi za bandwidth. Hari ubwoko bune bwo guhindura LAN:
Guhinduranya MLS mu byiciro byinshi;
Guhinduranya urwego rwa 4;
Guhinduranya urwego rwa 3;
Guhinduranya urwego rwa 2.
Guhindura LAN bikora gute?
Guhindura LAN ni switch ya Ethernet ikora ishingiye kuri protocole ya IP kandi itanga uburyo bworoshye bwo guhuza abatuma n'abakira binyuze mu muyoboro w'ibyambu n'amasano bihujwe. Iyi gahunda yemerera umubare munini w'abakoresha gusangira umutungo wa network. Guhindura LAN bikora nk'udushya twa packet kandi bishobora gucunga kohereza amakuru menshi icyarimwe. Ibi babikora basuzuma aderesi y'aho buri frame y'amakuru iherereye hanyuma bahita bayiyobora ku muyoboro runaka ujyanye n'igikoresho cyakira.
Inshingano y'ibanze ya switch ya LAN ni ukuzuza ibyifuzo by'itsinda ry'abakoresha kugira ngo bashobore kubona hamwe umutungo rusange kandi baganire neza. Mu gukoresha ubushobozi bwa switch za LAN, igice kinini cy'urujya n'uruza rw'itumanaho gishobora gushyirwa mu bice bito bya LAN. Uku gutandukanya LAN kugabanya neza urujya n'uruza rw'amakuru muri rusange, bigatuma kohereza amakuru no gukora neza kw'itumanaho birushaho koroha.
2 Guhindura SAN ni iki?
Guhindura SAN mu buryo bw’ikoranabuhanga ni uburyo bwihariye bwo guhuza seriveri n’ububiko rusange hagamijwe koroshya kohereza amakuru ajyanye n’ububiko.
Ukoresheje swichi za SAN, birashoboka gukora imiyoboro minini kandi yihuta yo kubika amakuru ihuza seriveri nyinshi kandi ikabona amakuru menshi, akenshi ikagera kuri petabytes. Mu mikorere yayo y'ibanze, swichi za SAN zihuza neza urujya n'uruza rw'abantu hagati ya seriveri n'ibikoresho byo kubika amakuru binyuze mu kugenzura paki no kuziyobora ku mpera zagenwe. Uko igihe cyagiye gihita, swichi zo kubika amakuru mu gace k'umuyoboro zagiye zihinduka kugira ngo zishyiremo ibintu bigezweho nko gusibanganya inzira, gusuzuma amakuru mu muyoboro, no kumenya amakuru mu buryo bwikora.
Ni gute swichi za Fibre Channel zikora?
Ihinduranya rya Fibre Channel ni igice cy'ingenzi muri SAN y'aho kubika amakuru, ifasha kohereza amakuru neza hagati ya seriveri n'ibikoresho byo kubika amakuru. Ihinduranya rikora binyuze mu gukora umuyoboro wihariye wihuta cyane wagenewe kubika no kugarura amakuru.
Mu by’ingenzi, switch ya Fibre Channel ikoresha ibikoresho na porogaramu byihariye kugira ngo icunge kandi iyobore urujya n’uruza rw’amakuru. Ikoresha protocole ya Fibre Channel, protocole ikomeye kandi yizewe y’itumanaho igenewe ibidukikije bya SAN. Uko amakuru yoherezwa kuva kuri seriveri ijya ku gikoresho cyo kubika amakuru, ndetse n’ibindi, ishyirwa mu mashusho ya Fibre Channel, bigatuma amakuru ahora neza kandi yihuta cyane.
Iyi switch ya SAN ikora nk'umupolisi wo mu muhanda kandi ikagena inzira nziza yo gukoresha amakuru muri SAN. Isuzuma aho amakuru aturuka n'aho agana muri Fibre Channel frames kugira ngo ikore neza mu gukwirakwiza amakuru. Iyi nzira y'ikoranabuhanga igabanya gutinda no gucucikana kw'amakuru, ikerekana ko amakuru agera aho agana vuba kandi mu buryo bwizewe.
Mu by’ukuri, swichi za Fibre Channel zitunganya urujya n’uruza rw’amakuru muri SAN, zigatuma imikorere n’ubwizerwe birushaho kuba byiza mu bidukikije birimo amakuru menshi.
3 Batandukanye bate?
Kugereranya switch ya LAN na switch ya SAN bishobora no gufatwa nko kugereranya switch ya SAN na switch ya network, cyangwa switch ya Fibre Channel na switch ya Ethernet. Reka turebe itandukaniro rikomeye riri hagati ya switch za LAN na switch za SAN.
Itandukaniro mu mikoreshereze
Imashini za LAN zabanje gukoreshwa ku miyoboro ya token ring na FDDI hanyuma ziza gusimburwa na Ethernet. Imashini za LAN zigira uruhare runini mu kunoza imikorere ya LAN no gukemura neza ibibazo bya bandwidth byari bihari. Imashini za LAN zishobora guhuza ibikoresho bitandukanye nka seriveri z'amadosiye, imashini zicapa, ububiko, mudasobwa, nibindi, kandi imashini za LAN zishobora gucunga neza urujya n'uruza rw'abantu hagati y'izi nzira zitandukanye.
Kandi switch ya SAN yagenewe imiyoboro ifite imikorere yo hejuru kugira ngo irebe ko amakuru adatinda cyane kandi nta gihombo atangwa. Yakozwe neza kugira ngo icunge neza imitwaro iremereye, cyane cyane mu miyoboro ifite imikorere yo hejuru ya Fibre Channel. Yaba Ethernet cyangwa Fibre Channel, imiyoboro ifite ububiko bw’amakuru yagenewe kandi itunganywa neza kugira ngo icunge urujya n’uruza rw’amakuru.
Itandukaniro mu mikorere
Ubusanzwe, swichi za LAN zikoresha umuringa na fibre kandi zikora ku miyoboro ya Ethernet ishingiye kuri IP. Guhindura LAN ya Layer 2 bitanga inyungu zo kohereza amakuru vuba no gutinda guke.
Irahebuje mu bintu nka VoIP, QoS na raporo ya bandwidth. Swichi za Layer 3 LAN zitanga ibintu bisa nka routers. Ku bijyanye na Layer 4 LAN Switch, ni verisiyo igezweho ya Layer 3 LAN Switch itanga porogaramu z'inyongera nka Telnet na FTP. Byongeye kandi, LAN Switch ishyigikira protocole zirimo ariko ntizigarukira kuri SNMP, DHCP, Apple Talk, TCP / IP, na IPX. Muri rusange, LAN Switch ni igisubizo cy'itumanaho gihendutse kandi cyoroshye gukoresha, gikwiriye cyane ku bigo n'ibikenewe mu mikoranire.
SAN switches zubakira ku rufatiro rw'imiyoboro y'ububiko ya iSCSI, irimo ikoranabuhanga rya Fibre Channel na iSCSI. Ikintu cy'ingenzi ni uko SAN switches itanga ubushobozi bwo kubika neza kurusha LAN switches. Fibre Channel switches ishobora kandi kuba Ethernet switches.
Byaba byiza, switch ya SAN ishingiye kuri Ethernet yagenewe gucunga urujya n'uruza rw'ububiko muri network ya IP storage area, bityo bigatuma habaho imikorere ishoboka. Nanone, binyuze mu guhuza switch za SAN, network nini ya SAN ishobora gushyirwaho kugira ngo ihuze seriveri nyinshi n'aho kubika amakuru.
4 Nigute nahitamo switch ikwiye?
Iyo utekereza ku guhindura LAN ugereranije na SAN, guhitamo switch ya LAN cyangwa switch ya SAN biba ingenzi cyane. Niba ibyo ukeneye birimo porogaramu zo gusangira dosiye nka IPX cyangwa AppleTalk, switch ya LAN ishingiye kuri IP ni yo mahitamo meza ku gikoresho cyo kubika. Ku rundi ruhande, niba ukeneye switch yo gushyigikira ububiko bushingiye kuri Fibre Channel, switch yo kubika ahantu hahurira umuyoboro irasabwa.
Imashini za LAN zoroshya itumanaho muri LAN binyuze mu guhuza ibikoresho biri muri network imwe.
Ku rundi ruhande, swichi za Fibre Channel zikoreshwa cyane cyane mu guhuza ibikoresho byo kubika kuri seriveri kugira ngo zibike neza kandi zigarure amakuru. Izi swichi ziratandukanye mu giciro, uburyo bwo kwaguka, imiterere y'aho ziherereye, umutekano, n'ubushobozi bwo kubika. Guhitamo hagati yazo biterwa n'ibisabwa byihariye byo gukoresha.
Guhinduranya LAN birahendutse kandi biroroshye kubishyiraho, mu gihe guhinduranya SAN bihenze cyane kandi bisaba uburyo bugoye bwo kubishyiraho.
Muri make, swichi za LAN na swichi za SAN ni ubwoko butandukanye bwa swichi za network, buri imwe ifite uruhare rudasanzwe muri network.
