LAN neSAN zvinomiririra Local Area Network neStorage Area Network, zvichiteerana, uye ese ari maviri ndiwo masisitimu makuru ekuchengetedza ari kushandiswa zvakanyanya nhasi.
LAN muunganidzwa wemakomputa nezvinhu zvinoshandisa waya kana waya zvinobatana nemaseva ari munzvimbo dzakasiyana dzenzvimbo. SAN iri mu network, kune rumwe rutivi, inopa kubatana nekukurumidza uye yakagadzirirwa network dzakavanzika, zvichibvumira kubatana kwemaseva akawanda nemidziyo yakasiyana-siyana yekuchengetera yakagovaniswa.
Saka, zvinhu zviviri zvakakosha zvinoshandiswa pakubatanidza network yemakombiyuta iLAN switches neSAN switches. Kunyangwe LAN switches neSAN switches dziri nzira dzekutaurirana data, dzine musiyano, saka ngatinyatsoongororai pazasi.
1 Chii chinonzi LAN switching?
Kuchinjana kweLAN inzira yekuchinjana mapaketi inoshandiswa pakutumira mapaketi pakati pemakombiyuta ari paLAN mukati me network yemunharaunda. Iyi nzira inoita basa rakakosha mukugadzira network uye inogona kuvandudza kushanda kweLAN zvakanyanya uye kuderedza zvipingamupinyi zvebandwidth. Kune mhando ina dzekuchinjana kweLAN:
Kuchinjana kweMLS muzvikamu zvakawanda;
Kuchinja kwechikamu chechina;
Kuchinja kwechikamu chechitatu;
Kuchinja kwechikamu chechipiri.
Switch yeLAN inoshanda sei?
LAN switch iEthernet switch inoshanda zvichibva paIP protocol uye inopa kubatana kunochinjika pakati pevatumi nevanogamuchira kuburikidza nenetwork yakabatana yemaports nemalink. Iyi gadziriro inobvumira nhamba huru yevashandisi vekupedzisira kugovera zviwanikwa zvenetwork. LAN switches dzinoshanda sema packet switches uye dzinogona kubata data transmissions dzakawanda panguva imwe chete. Dzinoita izvi nekuongorora kero yekuenda kwedata rega rega uye nekuiendesa pakarepo kune imwe port ine chekuita nechinhu chaunoda kugamuchira.
Basa guru reLAN switch nderekuzadzisa zvinodiwa neboka revashandisi kuitira kuti vagone kuwana pamwe chete zviwanikwa zvakagovaniswa uye kutaurirana zviri nyore. Nekushandisa kugona kweLAN switches, chikamu chikuru che network traffic chinogona kuwanikwa muzvikamu zveLAN zvishoma. Kupatsanurwa uku kunoderedza kuzara kweLAN, zvichikonzera kutamiswa kwedata uye kushanda kwenetwork zviri nyore.
2 Chii chinonzi SAN switching?
Kuchinja kweStorage Area Network SAN inzira yakakosha yekugadzira hukama pakati pemaseva nemapombi ekuchengetera akagovaniswa nechinangwa chekubatsira kutamisa data rine chekuita nekuchengetera.
Nemaswichi eSAN, zvinokwanisika kugadzira manetwork makuru ekuchengetera zvinhu anobatanidza maserver akawanda uye kuwana data rakawanda, kazhinji kusvika kumapetabytes. Mukushanda kwavo kwekutanga, maswichi eSAN anonyatso gadzirisa traffic pakati pemaseva nemidziyo yekuchengetera zvinhu nekutarisa mapaketi uye kuatungamira kune endpoints dzakatarwa. Nekufamba kwenguva, maswichi ekuchengetera nzvimbo yenetwork akashanduka kuti asanganise maficha epamusoro akadai se path redundancy, network diagnostics, uye automatic bandwidth sensing.
Maswichi eFibre Channel anoshanda sei?
Chinja cheFibre Channel chinhu chakakosha mu network yenzvimbo yekuchengetera data SAN inobatsira kutumira data zvakanaka pakati pemaseva nemidziyo yekuchengetera data. Chinja ichi chinoshanda nekugadzira network yakazvimirira inokurumidza kugadzirirwa kuchengetedza nekutora data.
Pachinyanya kukosha, switch yeFibre Channel inoshandisa hardware nesoftware yakasarudzika kuti itarisire uye itungamirire traffic yedata. Inoshandisa protocol yeFibre Channel, protocol yekutaurirana yakasimba uye yakavimbika yakagadzirirwa SAN environments. Sezvo data richitumirwa kubva kuseva kuenda kumudziyo wekuchengetera uye zvinopesana, rinoiswa mumafuremu eFibre Channel, zvichiita kuti data rive rakasimba uye rinokurumidza kutumirwa.
Switch yeSAN inoshanda semupurisa wemumugwagwa uye ndiyo inosarudza nzira yakanakisisa yekufambisa data kuburikidza neSAN. Inoongorora kero dzekwakabva nedzekwakaenda muFibre Channel frames kuti ikwanise kufambisa mapaketi zvakanaka. Kufambisa uku kwakangwara kunoderedza kunonoka uye kuzara, zvichiita kuti data risvike kwariri kuenda nekukurumidza uye zvakavimbika.
Chaizvoizvo, maswichi eFibre Channel anoronga kuyerera kwedata muSAN, zvichivandudza mashandiro uye kuvimbika munzvimbo dzine data rakawanda.
3 Vakasiyana sei?
Kuenzanisa switch yeLAN ne SAN switch kunogonawo kufungidzirwa sekufananidza switch yeSAN ne network switch, kana Fibre Channel switch ne Ethernet switch. Ngatitarisei musiyano mukuru uripo pakati pe LAN switches ne SAN switches.
Kusiyana Kwekushandisa
MaLAN switch akagadzirwa pakutanga ekushandisa ma token ring ne FDDI networks uye akazotsiviwa ne Ethernet. MaLAN switch anoita basa rakakosha mukuvandudza kushanda zvakanaka kwemaLAN uye kugadzirisa matambudziko aripo ebandwidth. MaLAN anogona kubatanidza zvishandiso zvakasiyana-siyana zvakaita semafaira servers, maprinta, ma storage arrays, ma desktops, nezvimwewo, uye maLAN switch anogona kugadzirisa traffic pakati pema endpoints aya akasiyana.
Uye switch yeSAN yakagadzirirwa network dzinoshanda zvakanyanya kuti ive nechokwadi chekuti data harina nguva yakawanda uye harina kurasikirwa. Yakagadzirwa nokungwarira kuti ikwanise kubata zvinorema zvekutengeserana, kunyanya mu network dzinoshanda zvakanyanya dzeFibre Channel. Ingave Ethernet kana Fibre Channel, network dzenzvimbo yekuchengetera dzakatsaurirwa uye dzakagadziriswa kuti dzibate traffic yekuchengetedza.
Kusiyana Kwekushanda
Kazhinji, maLAN switch anoshandisa copper nefiber interfaces uye anoshanda paIP-based Ethernet networks. Layer 2 LAN switching inopa mabhenefiti ekukurumidza kutamisa data uye kunonoka kushoma.
Inobudirira muzvinhu zvakaita seVoIP, QoS uye bandwidth reporting. Maswichi eLayer 3 LAN ane zvinhu zvakafanana nemarouters. Kana iri Layer 4 LAN Switch, ishanduro yepamusoro yeLayer 3 LAN Switch inopa mamwe maapplication akadai seTelnet neFTP. Pamusoro pezvo, LAN Switch inotsigira maprotocol anosanganisira asi asingagumiri kuSNMP, DHCP, Apple Talk, TCP/IP, uye IPX. Zvose zviri zviviri, LAN Switch imhinduro yenetworking isingadhuri, iri nyore kushandisa uye yakanakira zvinodiwa nebhizinesi ne networking yepamusoro.
Maswichi eSAN anovakirwa pahwaro hwemanetwork ekuchengetera eiSCSI, anosanganisira matekinoroji eFibre Channel neiSCSI. Chinhu chakakosha ndechekuti maswichi eSAN anopa kugona kwakanyanya kwekuchengetedza kupfuura maswichi eLAN. Maswichi eFibre Channel anogonawo kuva maswichi eEthernet.
Zvakanaka kuti switch yeSAN yakavakirwa paEthernet ishandiswe mukutarisira traffic yekuchengetera mukati me network yeIP storage area, nokudaro ichivimbisa kushanda kwakajairika. Zvakare, nekubatanidza switch dzeSAN, network yakakura yeSAN inogona kuumbwa kuti ibatane maseva akawanda uye nzvimbo dzekuchengetera.
4 Ndingasarudza sei switch chaiyo?
Pakufunga nezveLAN vs. SAN, kusarudza switch yeLAN kana SAN kunova kwakakosha. Kana zvaunoda zvinosanganisira maprotocol ekugovana mafaira akadai seIPX kana AppleTalk, saka switch yeLAN yakavakirwa paIP ndiyo sarudzo yakanakisa yemudziyo wekuchengetera. Kusiyana neizvi, kana uchida switch iyi kuti itsigire Fibre Channel-based storage, switch yekuchengetera nzvimbo yenetwork inokurudzirwa.
Maswichi eLAN anoita kuti kutaurirana kuve nyore mukati meLAN nekubatanidza zvishandiso zviri mukati me network imwe chete.
Kune rumwe rutivi, maswichi eFibre Channel anonyanya kushandiswa kubatanidza zvishandiso zvekuchengetera kumaseva kuti zvikwanise kuchengetwa zvakanaka uye kudzoserwa kwedata. Maswichi aya anosiyana pamutengo, kukura, topology, kuchengetedzeka, uye kugona kuchengetwa. Sarudzo pakati pawo inoenderana nezvinodiwa zvekushandisa.
Maswichi eLAN akachipa uye ari nyore kugadzirisa, nepo maswichi eSAN achidhura zvakanyanya uye anoda magadzirirwo akaomarara.
Muchidimbu, maswichi eLAN nemaswichi eSAN marudzi akasiyana eswichi dzenetwork, imwe neimwe ichiita basa rakasiyana munetwork.
