Lub sij hawm SAN hauv computer network feem ntau yog hais txog thaj tsam chaw sib tham tiam sis kuj tuaj yeem xa mus rau qhov chaw sib tham.
Ib cheeb tsam network thaj chaw yog ib hom ntawm cheeb tsam network (LAN) tsim los tswj xyuas cov ntaub ntawv loj thiab muaj kev khaws cov ntaub ntawv digital. TU SAN xws li txhawb cov ntaub ntawv cia, nqi thiab kev sib txuas ntawm kev lag luam tes hauj lwm uas siv cov kev ua lag luam siab, ntau disk arrays thiab interconnect tshuab.
Cov tes hauj lwm cia ua hauj lwm txawv dua li cov kev sib txuas ntawm cov neeg siv khoom-kev pab cuam vim yog qhov tshwj xeeb ntawm lawv cov haujlwm. Piv txwv, cov tuam txhab hauv tsev feem ntau pom cov neeg siv saib hauv Internet, uas muaj feem me me ntawm cov ntaub ntawv ua rau cov sij hawm sib txawv, thiab tuaj yeem kho qee qhov kev thov yog tias lawv tshwm sim tau poob. Cia tes hauj lwm, los ntawm kev sib piv, yuav tsum tau siv cov nqi loj heev ntawm cov ntaub ntawv tsim tawm hauv tej kev thov thiab tsis muaj peev xwm them tsis tau ib yam ntawm cov ntaub ntawv.
Ib qhov system hauv cheeb tsam yog ib pawg ntawm cov neeg siv kev ua haujlwm siab siv rau kev faib ua daim ntawv thov kom ceev ceev hauv zos cov kev ua haujlwm los pab txhawb kev sib txig sib luag thiab cov khoom siv tawm rau lwm cov neeg siv.
Fiber Channel thiab iSCSI
Qhov ob hom kev sib txuas lus sib txuas lus rau cov koom tes cia - Fiber Channel thiab Internet Me Computer Systems Interface (iSCSI) - muaj ob qho tib si tau siv hauv SAN thiab sib tw nrog lwm cov ntau xyoo.
Fiber Channel (FC) los ua qhov kev xaiv rau SAN network thaum nruab nrab ntawm xyoo 1990 mus. Cov kab ke Fiber Channel network muaj cov cuab yeej tshwj xeeb uas hu ua Fiber Channel keyboards uas txuas qhov chaw cia rau SAN thiab Fiber Channel HBAs (tus tswv tsev pib hu ua bus connectors) uas txuas cov keyboards no rau cov neeg siv Internet. FC txuas cov ntaub ntawv cov nqi ntawm 1 Gbps thiab 16 Gbps.
iSCSI yog tsim los ua tus nqi qis dua, qis dua qhov kev kawm rau Fiber Channel thiab pib zuj zus hauv qhov chaw nruab nrab thaum nruab nrab ntawm xyoo 2000s. iSCSI ua haujlwm nrog Ethernet keyboards thiab sib txuas sib txuas ua ke tsis siv cov cuab yeej tshwj xeeb uas ua rau cov haujlwm cia ua haujlwm. Nws muab cov ntaub ntawv ntawm 10 Gbps thiab siab dua.
iSCSI Appeals tshwj xeeb tshaj yog rau cov lag luam me uas feem ntau tsis muaj cov neeg ua haujlwm tau txais kev pabcuam hauv kev tswj fibre Technology. Ntawm qhov tod tes, cov koom haum twb paub txog Fiber Channel ntawm keeb kwm tsis xav tias yuav tsum qhia kom paub iSCSI rau hauv lawv qhov chaw. Lwm daim ntawv hu ua FC Fiber Channel nyob Ethernet (FCoE) tau tsim los txo cov nqi ntawm FC cov kev daws teebmeem los ntawm qhov kev xav tau yuav khoom muas khoom HBA. Tsis yog txhua qhov Ethernet hloov qhov kev pab txhawb FCoE, li cas los xij.
SAN khoom
Cov neeg paub zoo txog cov chaw kaw khoom hauv network yog EMC, HP, IBM, thiab Brocade. Ntxiv nrog rau cov keyboards hauv FC thiab HBAs, cov neeg muag khoom tseem muag cov chaw cia khoom thiab khib nyiab rau lub cev tawm suab. Tus nqi ntawm cov cuab yeej siv li ntawm ob peb txhiab li txog txhiab tus las.
SAN thiab NAS
SAN tshuab zoo ib yam, tiam sis txawv txav ntawm lub network txuas (NAS) technology. Thaum SANs feem ntau siv cov kev cai sib tham tsawg-npaum li kev xa tawm cov block blocks, tus NAS ntaus ntawv feem ntau ua haujlwm tshaj TCP / IP thiab tuaj yeem ua tau yooj yim rau hauv computer lub computer network .
