Lub sij hawm SAN hauv kev sib txuas hauv computer feem ntau yog hais txog kev sib txuas hauv cheeb tsam tab sis kuj tuaj yeem xa mus rau qhov system cheeb tsam networking.
Ib qhov chaw cia khoom yog ib hom kev sib txuas hauv cheeb tsam hauv cheeb tsam (LAN) uas tswj cov ntaub ntawv loj thiab khaws cov ntaub ntawv digital. A SAN feem ntau txhawb nqa cov ntaub ntawv khaws cia, rov qab thiab rov ua dua ntawm kev lag luam tes hauj lwm siv cov servers siab kawg, ntau lub disk arrays thiab kev sib txuas thev naus laus zis.
Storage Networks vs. Client-Server Networks
Cov chaw khaws cia ua haujlwm sib txawv ntawm cov neeg siv khoom-neeg rau zaub mov sib txuas vim qhov tshwj xeeb ntawm lawv cov haujlwm ua haujlwm. Piv txwv li, hauv tsev tes hauj lwm ib txwm muaj cov neeg siv tshawb hauv Is Taws Nem, uas muaj cov ntaub ntawv me me ntawm lub sijhawm sib txawv. Lawv kuj tuaj yeem xa rov qab qee qhov kev thov yog tias lawv tshwm sim poob.
Cia cov tes hauj lwm, los ntawm kev sib piv, tswj cov ntaub ntawv ntau hauv kev thov ntau thiab tsis tuaj yeem them taus cov ntaub ntawv poob. Lub system cheeb tsam network yog ib pawg ntawm cov khoos phis tawj ua haujlwm siab. Nws tsim nyog rau kev faib cov ntawv thov uas xav tau kev ua haujlwm hauv zos ceev ceev los txhawb kev sib koom ua ke thiab tso tawm rau cov neeg siv sab nraud.
Fibre Channel vs. iSCSI
Ob txoj kev sib txuas lus tseem ceeb rau kev sib txuas lus - Fiber Channel thiab Internet Small Computer Systems Interface (iSCSI) - tau tshwm sim hauv SANs thiab sib tw nrog ib leeg rau ntau xyoo.
Fibre Channel (FC) tau dhau los ua qhov kev xaiv rau SAN networking thaum nruab nrab-1990s. Ib txwm Fiber Channel tes hauj lwm muaj cov khoom siv tshwj xeeb uas hu ua Fiber Channel keyboards uas txuas cov chaw cia rau SAN. Fiber Channel HBAs (tus tswv tsheb npav adapters) txuas cov keyboards no rau cov khoos phis tawj server. FC kev sib txuas muab cov ntaub ntawv tus nqi ntawm 1 Gbps thiab 16 Gbps.
iSCSI yog tus nqi qis dua, kev ua haujlwm qis dua rau Fiber Channel thiab pib loj hlob hauv cov koob npe thaum nruab nrab-2000s. iSCSI ua haujlwm nrog Ethernet keyboards thiab kev sib txuas ntawm lub cev es tsis txhob siv cov khoom siv tshwj xeeb tsim tshwj xeeb rau kev khaws cia ua haujlwm. Nws muab cov ntaub ntawv tus nqi ntawm 10 Gbps thiab siab dua.
iSCSI thov tshwj xeeb rau cov lag luam me uas feem ntau tsis muaj cov neeg ua haujlwm siab rau tswj hwm Fiber Channel thev naus laus zis. Cov koom haum twb tau ntsib hauv Fiber Channel yuav tsis qhia iSCSI rau hauv lawv ib puag ncig. Lwm daim ntawv ntawm FC hu ua Fiber Channel hla Ethernet (FCoE) lowers tus nqi ntawm FC cov kev daws teeb meem los ntawm kev tshem tawm qhov xav tau los yuav HBA kho vajtse. Tsis yog txhua qhov hloov pauv Ethernet txhawb FCoE, txawm li cas los xij.
kab hauv qab
Nyob zoo cov neeg tsim khoom ntawm thaj chaw cia khoom siv suav nrog EMC, HP, IBM, thiab Brocade. Nrog rau FC keyboards thiab HBAs, cov neeg muag khoom muag cov chaw cia khoom thiab khib nyiab rau lub cev disk media. Tus nqi ntawm SAN cov cuab yeej muaj txij li ob peb puas mus txog txhiab las.
SAN vs. NAS
SAN thev naus laus zis zoo ib yam tab sis txawv ntawm lub network txuas nrog cia (NAS) thev naus laus zis. Thaum SANs ib txwm siv cov txheej txheem qis qis rau kev hloov cov disk blocks, NAS ntaus ntawv feem ntau ua haujlwm dhau TCP / IP thiab tuaj yeem sib txuas nrog cov khoos phis tawj hauv tsev yooj yim.
