Qhov sib txawv tseem ceeb ntawm SAN thiab NAS yog SAN yog qhov thaiv qib cov ntaub ntawv khaws cia thaum NAS yog cov ntaub ntawv qib cov ntaub ntawv khaws cia.
Niaj hnub no thev naus laus zis tau nce siab heev uas tau ua rau peb lub neej yooj yim dua thiab xis nyob. Txhua yam tau ploj mus rau digital tam sim no, yav dhau los cov neeg siv los ua lawv txoj haujlwm manually thiab ntawm cov ntaub ntawv thiab txuag thiab teeb tsa tag nrho nws nyuaj heev tab sis tam sim no thev naus laus zis tau ua rau txhua yam yooj yim thiab yooj yim rau peb siv. Kev nce qib hauv kev siv thev naus laus zis coj nws mus rau theem ntxiv los ntawm kev tsim kho thev naus laus zis thiab txawm tias ua raws li peb cov kev xav tau nce ntxiv ntawm kev khaws cia thiab ua cov ntaub ntawv ntau thiab cov ntaub ntawv. Tom qab kev cia ncaj qha, qhov chaw cia khoom network thiab kev sib txuas nrog lub network tau qhia ua kom peb cov kev paub txog kev suav tau siv tau ntau dua.
SAN yog dab tsi?
SAN stands for Storage Area Network. Nws yog ib qho khoom siv cia. Nyob rau hauv lwm yam lus, nws yog ib tug network ntawm cia disks. Lub hom phiaj ntawm kev tsim cov chaw cia khoom network yog los tswj cov ntaub ntawv loj. Rau qhov ntawd, SAN txuas ntau lub tshuab server mus rau ib qho chaw khaws cia tseem ceeb. Cov tes hauj lwm no siv thev naus laus zis ntawm fiber ntau channel fabrics tshwj xeeb uas tsim los rau kev sib txuas lus cia xav tau.
Daim duab 01: SAN
Muaj ntau qhov zoo ntawm SAN. Ua ntej, nws yooj yim rau kev tswj hwm cov haujlwm thiab ua kom yooj yim rau kev tswj thiab kho txhua lub tuam txhab khaws cia. Qhov thib ob, nws tso cai rau sib koom cov ntaub ntawv los ntawm ntau lub tshuab. Nws txuag lub sijhawm thiab cov txiaj ntsig ntawm cov neeg siv khoom thiab tseem ua rau kom muaj peev xwm siv tau. Nyob rau hauv luv luv, Storage Area Networks yog ceev dua thiab txhim khu kev qha rau kev nkag tau tshaj li lwm yam cia li.
NAS yog dab tsi?
NAS sawv cev rau Network-Atached Storages uas yog cov chaw cia khoom nyob deb. NAS tseem muab ntau yam zoo rau cov neeg siv. Cov ntaub ntawv nkag tau sai dua thiab muaj kev teeb tsa yooj yim. Ntxiv rau qhov ntawd, NAS txo tus nqi server thiab txo tus nqi txuas ntxiv. Raws li qhov tshwm sim, nws ua rau kom muaj peev xwm tswj tau cov ntaub ntawv khaws cia.
Figure 02: NAS
Tsis tas li ntawd, NAS yog txoj hauv kev yooj yim rau khaws cov ntaub ntawv thiab cov ntaub ntawv thaum sib koom cov ntaub ntawv ntawm ntau lub khoos phis tawj. Hauv luv luv, NAS yog tus nqi qis dua thiab yooj yim rau cov neeg siv dua SAN.
Qhov txawv ntawm SAN thiab NAS yog dab tsi?
SAN vs NAS |
|
| Ib lub computer network uas muab kev nkag mus rau kev sib sau ua ke, thaiv qib cov ntaub ntawv khaws cia. | Ib theem cov ntaub ntawv khaws cia server txuas nrog lub khoos phis tawj network muab cov ntaub ntawv nkag mus rau pawg neeg sib txawv ntawm cov neeg siv khoom. |
| Stands for Storage Area Network. | Stand rau Network-Atached Cia. |
| Level of Data Storage | |
| Siv Thaiv qib. | Siv cov ntaub ntawv qib. |
| Kev tswj hwm | |
| Kev tswj hwm SAN nyuaj dua NAS. | Tswj NAS yooj yim dua SAN. |
| Tus nqi | |
| SAN yog qhov dav dua NAS. | NAS yog tus nqi qis dua qhov chaw cia hauv cheeb tsam rau nws cov neeg siv los tswj thiab ua haujlwm. |
| Txoj Kev Sib Txuas | |
| Tsuas yog chav kawm server SCSI lossis Fiber Channel tuaj yeem txuas rau SAN. | Txhua lub tshuab uas tuaj yeem txuas rau LAN tuaj yeem siv NFS, CIFS lossis HTTP raws tu qauv los txuas rau NAS thiab faib cov ntaub ntawv. |
| Kev tsim nyog | |
| Tsim nyog rau kev lag luam loj thaub qab lub hom phiaj. Haum rau cov neeg siv khoom loj. | Haum rau kev lag luam me me thaub qab lub hom phiaj. |
Summary – SAN vs NAS
Peb lub ntiaj teb thiab thev naus laus zis hloov pauv tas li, thiab txhua lub sijhawm peb yuav tsum ua raws li kev tsim kho tshiab thiab thev naus laus zis tshiab. SAN thiab NAS yog cov thev naus laus zis niaj hnub no uas ua rau peb txoj haujlwm thiab lub neej yooj yim dua los ntawm kev txuag lub sijhawm, kev siv zog, nyiaj txiag thiab kev txawj ntse. Qhov txawv ntawm SAN thiab NAS yog tias SAN yog qhov thaiv qib cov ntaub ntawv khaws cia thaum NAS yog cov ntaub ntawv qib cov ntaub ntawv khaws cia.
