Tsanangudzo Yekuchengetedzwa Kwemakambani Masangano uye Network Yakachengetedzwa Kuchengetedzwa
Kuchengetedza nzvimbo mitambo (SANs) uye nhandare yakachengetedzwa kuchengetedzwa (NAS) zvose zviri zviviri zvinopa matanho ekuchengetedza maitiro. A NAS imwe chipfeti yekuchengetedza iyo inoshanda pamatafura e data, apo SAN inzvimbo yekunzvimbo dzakawanda dzezvigadzirwa.
Kusiyanisa pakati peNAS neSAN kunogona kuonekwa pakufananidza kukanda kwavo uye kuti vanobatana sei nehurongwa, uyewo kuti mamwe magetsi anotaura sei navo. Zvisinei, iyo mbiri dzimwe nguva inoshandiswa pamwe kuumba izvo zvinozivikanwa seSAN yakabatana.
SAN vs. NAS Technology
Chimwe chikamu cheNAS chinosanganisira hardware yakazvitsaurira iyo inobatanidza kune inzvimbo yekambani , kakawanda kuburikidza nehutano hweEthernet . Iyi seva yeNAS inonyatsosimbisa vatengi uye inochengetedza mafaira ekufambisa nenzira yakafanana nemasipiresi emafaira, kuburikidza nemitemo yakagadzirwa zvakanaka.
Kuti kuderedze mari inowanzoitika nemasipiresi emafaira, maNAS maitiro anowanzoshanda purogiramu yekushanda yakaiswa pane hardware isina kuoma uye kushaikwa kwezvipfeko zvakadai sekuona kana keyboard uye panzvimbo ino zvinotungamirirwa kuburikidza nechigadzirwa cheshandisi.
A SAN inowanzoshandisa Fiber Channel inosangana uye inobatanidza seti yezvigadzirwa zvekuchengetedza zvinokwanisa kugovana dhana.
Zvinokosha NAS neSAN Benefits
Mutevedzeri weimba kana bhizinesi rebhizimisi rinogona kuunganidza imwe NAS yedhiyo kune imwe nzvimbo yenzvimbo. Chigadziro chacho pachayo node yehutano , yakawanda semakombiyuta uye mamwe maTCP / IP maikirwo, ose anochengetedza pachake kero yeP IP uye anokwanisa kutaurirana nemamwe maikirwe emagetsi.
Zvichipa kuti mambure akabatanidza chigadziro chekuchengetedza akabatanidzwa kumatareti , mamwe mazvigadzirirwo emutambo iwoyo anenge achiwana nyore nyore (zvichipiwa kuti mvumo yakakodzera inogadzirirwa). Nemhaka yehutano hwavo, NAS mazano anopa nzira iri nyore yevashandisi vakawanda kuti vawane data yakafanana, iyo inokosha mumamiriro ezvinhu apo vashandi vari kubatanidzwa pamapurojekiti kana kushandisa imwechete yekambani.
Kushandisa purogiramu yeprogram inopiwa neNAS hardware, network administrator inogona kugadzira zvinyorwa zvinotsvaga kana zvinyorwa zvekunyora uye mafaira emapakati pakati peNAS nedzimwe dzose dzakabatana. Nokudaro, chigadzirwa cheNAS chinobatsirawo nokuda kwechikonzero chinopesana: kubudisa dunhu rekushandisa kune network network storage chikafu chikuru chekuchengetedza chigadziko.
Izvi zvinobatsira kwete kungovimbisa kuti vashandi havasi kurasikirwa ne data, sezvo NAS inogona kutsigirwa purogiramu yenguva dzose zvisinei nokuti kugona kwemushandi-kukwanisa kugadzirisa, asiwo kupa mamwe maikirwe emagetsi nzvimbo yekuchengeta mafayela makuru, kunyanya mafaira makuru anowanzogoverwa pakati pevamwe vashandisi veseve.
Pasina NAS, vashandisi vanofanira kuwana imwe (kazhinji inononoka) zvinoreva kutumira data kune mamwe maikirwo pamutambo, kufanana neam email kana mumuviri nekutyaira . NAS inobata akawanda gigabytes kana tadabytes yedata, uye vatungamiri vanogona kuwedzera humwe ruzivo rwekuchengetedza kumaketheni avo nekuisa mamwe madivayiri eNAS, kunyange zvazvo NAS imwe neimwe inoshandisa zvakasununguka.
Vatungamiri vemabhizimisi makuru ehurumende vanogona kutoda akawanda tetabytes ye centralized file yekuchengetedza kana zvakanyanya zvikuru-speed file kushandiswa kwemabasa. Paunenge uchiisa uto rezvikwata zvakawanda zveNAS haisi nzira yakakodzera, vatungamiri vanogona panzvimbo panzvimbo yekuisa SAN ine yepamusoro-performance disk array kuti ipe kudikanwa kwekudiwa nekushanda.
Zvisinei, maSAN haasi nguva dzose mumuviri. Iwe unogonawo kuumba SANS (VSANs) zvakasarudzwa zvinorondedzerwa neprogram ye software. Virtual SANs zviri nyore kuchengetedza nekupa zviri nani zvishoma nezvishoma sezvo iine hardware yakasununguka uye inodzorwa zvachose ne nyore nyore kuchinja software.
SAN / NAS Convergence
Sokutengeserana kwekombiyuta seTCP / IP uye Ethernet inowedzera pasi pose, dzimwe sangano reSAN dziri kuita shanduko kubva kuFiber Channel kuenda kune imwecheteyo IP-based nzira inoshandisa NAS. Uyewo, nekuvandudzika nokukurumidza kwekodhidhikiti yekuchengetedza, matsva anhasi eNAS anopa kupa ruzivo uye kushanda kwaimbova kungoita ne SAN.
Izvozvi makambani maviri emakambani akaendesa kushanduka kwechikamu cheNAS uye SAN inoswedera kunzvimbo yekuchengetedza, kuchengetedza nekugadzira zvakakwirira-refu, yakakwirira-kukwanisa, nzvimbo yakagadzirwa nemagetsi.
Apo SAN neNAS zvakabatanidzwa pamwe chete mune imwe nhumbi nenzira iyi, dzimwe nguva inonzi "unonzi SAN yakabatana," uye kazhinji ndeyekuti iyo chiyero chimbo cheNAS chinoshandisa chete tekinoloji imwechete seri kweSAN.
