Izwi rokuti SAN mumakombiyuta ekutengesa yakawanda rinowanzoreva kunzvimbo yekuchengetedza nzvimbo yekutengesa asi rinogonawo kureva kushandiswa kwenzvimbo kunzvimbo.
Nzvimbo yekuchengetedza nzvimbo inonzi inzvimbo yemunharaunda yenzvimbo (LAN) yakagadzirirwa kutakura hurukuro dzekuwedzerwa kwemashoko uye kuchengetedzwa kwehuwandu hwehuwandu hwemagetsi. A SAN inowanzochengetedza kuchengetedza kwekuchengetedza, kutora uye kudzokorora pamabhizimisi mashandisi achishanda mapeji ekupedzisira, multiple disk arrays uye interconnect teknolojia.
Masangano ekuchengetedza anoshandiswa zvakasiyana nekushambadzirana nevatengi-server mitero nekuda kwehutano hwemabasa avo. Semuenzaniso, mapepa emisha anowanzoshandisa vanoshandisa kuongorora Indaneti, iyo inosanganisira zviduku zvishoma zvemari zvakagadziriswa panguva dzakasiyana, uye inogona kudzorera zvimwe zvikumbiro kana zvikaitika kuti dzarasika. Kuchengetedza mitambo, nekuenzanisa, inofanira kushanda yakawanda kwazvo ye data yakagadzirwa zvikumbiro zvakawanda uye haikwanisi kurasikirwa chero dhe data.
A system nzvimbo network inosanganisira mashizha emakombiyuta akakwirira anoshandiswa kugadziriswa kushandiswa kwezvirongwa zvinoda kukurumidza nzvimbo yebasa rekushanda kutsigira kuenzaniswa kwehutano uye kuwanikwa kune vashandisi vekunze.
Fiber Channel vs. iSCSI
Izvo zviviri zvinoshandiswa pakukurukurirana kwemichina yekuchengetedza mitambo - Fiber Channel neInternet Small Computer Systems Interface (iSCSI) - zvose zviri kushandiswa zvakanyanya muSAN uye dzakakwikwidzana mumwe nemumwe kwemakore akawanda.
Fiber Channel (FC) yakava sarudzo inotungamirira kuSAN mitambo mukati me1990. Traditional Fiber Channel network dzine hardware inonzi-purpose inonzi Fiber Channel switches iyo inounganidza kuchengetedza kune SAN plus Fiber Channel HBAs (mauto adapter mabhasi) anobatanidza izvi kushandura makombiyuta e server. FC kufambidzana kunopa dhidha yakaenzana pakati pe1 Gbps uye 16 Gbps.
iSCSI yakasikwa semari yakaderera, kushandiswa kwepasi kwakasiyana kune Fiber Channel uye yakatanga kukura mukuzivikanwa pakati pe2000. iSCSI inoshanda neEthernet switches uye kuwirirana kwepanyama panzvimbo yeiyo hardware chaiyo yakagadzirirwa zvakakwana kuchengetedza mabasa ekuchengetedza. Inopa huwandu hwemashoko e10 Gbps uye yakakwirira.
iSCSI zvikumbiro zvikuru kunyanya kumabhizimisi mashomanana avo kazhinji vasina vashandi vanodzidziswa muhutungamiri hweFiber Channel technology. Kune rumwe rutivi, masangano akatove akawana muFiber Channel kubva munhoroondo angave asinganzwi achimanikidzwa kuunza iSCSI munzvimbo yavo. Chimwe chimiro che FC chinonzi Fiber Channel pamusoro peEthernet (FCoE) chakagadzirirwa kuderedza mari yeC FC mhinduro nekubvisa kudiwa kwekutenga hardware yeHBA. Hasi yose Ethernet switches inotsigira FCoE, zvisinei.
SAN Products
Vadzivisi vanozivikanwa vekuchengetedza nzvimbo yemashandisirwo emitambo vanosanganisira EMC, HP, IBM, uye Brocade. Mukuwedzera kune FC switches neHBAs, vatengesi vanogadzirisawo nzvimbo dzekuchengetedza uye zvigaro zvekuchengetedza kwemaviri disk media. Mari inoshandiswa neSAN imomo kubva kune mazana mashomanana kusvika kune zviuru zvemadhora.
SAN vs. NAS
SAN teknolojia inofanana asi yakasiyana nedzimwe sangano rakachengetedzwa (NAS) teknolojia. Kunyange zvazvo veSAN vanogara vachishandisa zvidzidzo zvepamusoro-purogiramu zvekutengesa dhiki, chimbo cheNAS chinowanzoshanda pamusoro peTCP / IP uye chinogona kusanganiswa zvakanaka nyore nyore mumakombiyuta epamba .
