Ndemanga ya yosungirako malo osungirako ndi malo osungirako zinthu
Malo osungirako malo osungirako zinthu (SANs) ndi malo osungirako malonda (NAS) onsewa amapereka njira zothetsera malonda. NAS ndi chipangizo chosungiramo chimodzi chomwe chikugwira ntchito pa mafayilo a deta, pamene SAN ndi malo ochezera a zipangizo zambiri.
Kusiyanitsa pakati pa NAS ndi SAN kungaoneke poyerekeza kanyumba kawo ndi momwe akugwirizanirana ndi dongosolo, komanso momwe zipangizo zina zimalankhulira nawo. Komabe, nthawi zina amagwiritsidwa ntchito palimodzi kuti apange zomwe zimadziwika ngati SAN yogwirizana.
SAN vs. NAS Technology
Chigawo cha NAS chimaphatikizapo chipangizo chodzipereka chomwe chimagwirizanitsa ndi intaneti , nthawi zambiri kudzera mu mgwirizano wa Ethernet . Seva iyi ya NAS imatsimikiziranso makasitomala ndipo imayendetsa mafayilo mofanana mofanana ndi ma seva a fayilo, kupyolera muzinthu zolumikizidwa bwino.
Kuti muchepetse ndalama zomwe zimachitika ndi ma seva apamwamba, zida za NAS zimayendetsa kayendedwe ka zinthu zomwe zimakhala zosavuta komanso zovuta zowoneka ngati khungu kapena makanema ndipo m'malo mwake zimagwiritsidwa ntchito pogwiritsa ntchito osatsegula.
A SAN amagwiritsira ntchito kwambiri Fiber Channel ndipo amagwirizanitsa zida zosungirako zomwe zimatha kugawa deta wina ndi mnzake.
Chofunika kwambiri cha NAS ndi SAN Benefits
Wotsogolera nyumba kapena makina ochepa a bizinesi akhoza kugwirizanitsa chipangizo chimodzi cha NAS ku intaneti. Chipangizo chomwecho ndi nambala yachinsinsi , monga makompyuta ndi zipangizo zina za TCP / IP , zonse zomwe zimakhala ndi adilesi yawo ya IP ndipo zingathe kuyankhulana bwino ndi zipangizo zina.
Popeza kuti makina omwe amasungirako chipangizocho akuphatikizidwa pa intaneti , zipangizo zina zonse zomwe zimagwiritsidwa ntchito pamtaneti womwewo zimakhala zosavuta kuzigwiritsa ntchito (kupatsidwa kuti zilolezo ziyenera kukhazikitsidwa). Chifukwa cha chikhalidwe chawo, zida za NAS zimapereka njira zosavuta kuti ogwiritsa ntchito angapeze deta yomweyi, yomwe ndi yofunika kwambiri pamene anthu akugwirizanitsa ntchito kapena kugwiritsa ntchito makampani omwewo.
Pogwiritsa ntchito pulogalamu yamapulogalamu opangidwa ndi NAS hardware, wolamulira wogwiritsa ntchito makina angathe kukhazikitsa zolemba zowonjezera kapena zolembedwa pamanja pakati pa NAS ndi zipangizo zina zogwirizana. Choncho, chipangizo cha NAS chimathandizanso pa chifukwa chosiyana: kusungunula deta yapafupi ku chipangizo chotetezera kusungirako chidebe chokwanira kwambiri.
Izi ndizothandiza osati kungoonetsetsa kuti ogwiritsira ntchito samasokoneza deta, popeza NAS ikhoza kuthandizidwa pa ndondomeko ya nthawi zonse mosasamala kanthu za kuthekera kwa wogwiritsa ntchito mapeto, komanso kupereka zipangizo zina zamakono malo oti asunge mafayela aakulu, makamaka mafayilo akuluakulu omwe nthawi zambiri amawagawa pakati pa ogwiritsa ntchito intaneti.
Popanda NAS, ogwiritsa ntchito ayenera kupeza wina (nthawi zambiri amachedwetsa) amatanthawuza kutumiza deta kuzinthu zina pa intaneti, monga ma imelo kapena thupi ndi magetsi . NAS imatenga ma gigabytes ambiri kapena ma terabytes a deta, ndipo olamulira akhoza kuwonjezera mphamvu yongosungira kumtunda wawo mwa kukhazikitsa zipangizo zina za NAS, ngakhale kuti NAS iliyonse imagwira ntchito mosiyana.
Olamulira a maofesi akuluakulu amalonda angafunike maofesi ambiri otetezera mafayilo kapena otchuka kwambiri. Pamene kukhazikitsa gulu lazinthu zambiri za NAS sizothandiza, otsogolera angathe kukhazikitsa SAN omwe ali ndi ma diski akuluakulu kuti apange zofunikira komanso zofunikira.
Komabe, SANs si nthawi zonse zakuthupi. Mukhozanso kupanga SANs (VSANs) zomwe zimafotokozedwa ndi pulogalamu ya pulogalamu. SANs zabwino zimakhala zosavuta kusamalira komanso kupereka bwino kwambiri popeza ali hardware omwe amadziimira okhaokha ndipo amawongolera kwathunthu ndi mapulogalamu osavuta kusintha.
SAN / NAS Convergence
Monga ma tekinoloje a intaneti monga TCP / IP ndi Ethernet ikufalikira padziko lonse, mankhwala ena a SAN akusintha kuchoka ku Fiber Channel kupita ku njira yomweyo ya IP yomwe imagwiritsa ntchito NAS. Ndiponso, ndi kusintha kofulumira mu teknoloji yosungirako disk, zipangizo zamakono za NAS tsopano zimapereka mphamvu ndi ntchito zomwe poyamba zinkatheka ndi SAN.
Zotsatira ziwirizi zimayambitsa kusintha kwa NAS ndi SAN kuyandikira kusungirako mafakitale, ndikupanga bwino kupanga makina apamwamba kwambiri, omwe ali pamtunda.
Pamene SAN ndi NAS akuphatikizidwa pamodzi mu chipangizo chimodzi motere, nthawi zina amatchedwa "SAN ogwirizana," ndipo nthawi zambiri zimakhala kuti chipangizo ndi chipangizo cha NAS chomwe chimagwiritsira ntchito telojiya yomweyo kumbuyo kwa SAN.
