Optical fiber network card, optical fiber Ethernet network card lossis optical fiber Ethernet adapter. Cov khoom sib kis tau yog TCP / IP Ethernet raws tu qauv, uas feem ntau txuas nrog cov kab hluav taws xob channel hloov mus rau fiber ntau cable. Cov hom interface tau muab faib ua qhov chaw nres nkoj kho qhov muag thiab chaw nres nkoj hluav taws xob. Optical ports feem ntau xa cov ntaub ntawv los ntawm cov kab hluav taws xob fiber ntau. Lub tshuab sib txuas hauv nruab nrab yog feem ntau SFPs thiab GBICs, thiab qhov cuam tshuam sib txuam yog SC thiab LC. Lub interface ntawm hom hluav taws xob chaw nres nkoj feem ntau yog DB9 tus pin lossis HSSDC.
100m optical fiber network daim npav yog network txuas nrog 100Mbps Fast Ethernet optical fiber nkag, txhawb tag nrho duplex, Ib nrab duplex; nws yog qhov tshwj xeeb tshaj yog rau cov chaw uas qhov kev ncua deb ntawm cov ntaub ntawv nkag kis tau dhau qhov kev nkag mus ntawm chav kawm 5 cable (100m), thiab tuaj yeem hloov tag nrho cov qauv network ntawm sab nraud photoelectric converter nrog RJ45 interface Ethernet daim npav, muab cov neeg siv nrog kev daws teeb meem ntawm fiber ntau tsev thiab fiber ntau rau desktop. Tus neeg siv tuaj yeem xaiv cov kev sib txuas ntawm cov kab hluav taws xob fiber ntau (suav nrog txuas, ib hom / ntau hom kho qhov muag, ua haujlwm nyob deb, thiab lwm yam) raws li daim ntawv thov teeb meem.
32/64 ntsis PCI npav network interface daim npav yog siv los tsim kev sib txuas ntawm PC lossis server thiab hloov mus daws cov teeb meem kev daws teeb meem ntawm server network card hauv Intranet hom. Cov khoom muab cov hluav taws xob fiber ntau kis nruab nrab interface, 32/64 ntsis / 66MHz compact PCI npav interface, uas muaj tseeb txhawb kev xa khoom tau zoo; kev sib txuas lus sib txuas tswj nti txo lub siab ntawm CPU cov ntaub ntawv ua; ntxiv rau, nws tseem muab VLAN tag, cov ntaub ntawv ntws tawm ua ntej, tswj hwm lub zog thiab lwm yam kev ua haujlwm ntse; tib lub sijhawm, cov tsev qiv ntawv tsav tsheb nplua nuj pab txhawb ntau lub operating system platform.
Vim li cas siv 10G NIC los tsim NAS cia lub network?
Hauv NAS cia network, txoj haujlwm tseem ceeb ntawm daim npav network yog pab NAS kom paub txog kev sib koom tes, thiab tso cai rau cov neeg siv tas los khaws thiab nyeem cov ntaub ntawv hauv NAS los ntawm daim npav network.
Tam sim no, nrog kev hloov kho thev naus laus zis, NAS nco nrog Gigabit ceev tsis tuaj yeem ua kom tau raws li qhov kev xa xov nrawm ntawm cov ntaub ntawv loj thiab cov ntaub ntawv multimedia. Nyob rau tib lub sijhawm, suav hais tias 10G network khoom siv (xws li 10G network hloov, 10G Optical modules, thiab lwm yam) tau siv dav hauv cov chaw loj thiab lwm cov teb, thiab 10G network kev ua lag luam tau paub tab, nws yog qhov yuav tsum tau hloov kho NAS muaj cia lub network rau 10G network.
Tam sim no, nyob rau hauv lub caij nyoog ntawm cov ntaub ntawv no tawg, qhov kev loj hlob ntawm cov ntaub ntawv tsis txaus ntseeg coj qhov kev tsis txaus siab tsis txaus ntseeg rau SMEs thiab cov tub txawg. Txawm hais tias huab cia, qhov kev pheej hmoo ntawm cov ntaub ntawv poob kuj tseem ntau. Yog li ntau lub chaw lag luam tig mus rau NAS cia.
NAS yog dab tsi?
Lub npe tag nrho ntawm NAS yog network txuas cia. Hauv ntej, NAS yog qhov chaw khaws cia. NAS pab kiag li tuaj yeem khaws thiab faib cov ntaub ntawv los ntawm ntau lub khoos phis tawj. Nws tuaj yeem nkag mus rau nws cov ntaub ntawv hauv thaj chaw npog ntawm lub network khaws cia, thiab nws kuj tuaj yeem nkag mus saib chaw nyob hauv Is Taws Nem.
NAS raws li lub chaw khaws ntaub ntawv, nws txoj haujlwm tseem ceeb yog chaw cia khoom, sib sau lub tsev lossis chaw ua haujlwm ntaub ntawv. Qhov sib txawv loj tshaj ntawm NAS cia thiab tsis yog NAS yog kev sib koom ntawm cov chaw cia, uas ntau lub zog tuaj yeem pom tau hais tias: cov ntaub ntawv sib txuas, kev sib qhia duab, cov nkauj music, lub tsev qiv ntawv video, rub tawm, cov ntaub ntawv thaub qab thiab lwm yam.
Peb yam ntxwv ntawm NAS cia:
1. Muaj peev xwm loj - NAS cia nws muaj nws qhov tshwj xeeb kev nthuav dav. Piv nrog rau lwm cov khoom siv thev naus laus zis zoo, nws lub peev xwm cia muaj peev xwm loj heev. Nws tuaj yeem tso ntau lub hard disk peev xwm los nthuav cov qauv cia.
2. Kev siv cov ntaub ntawv: txhua cov cuab yeej tuaj yeem nkag mus rau cov ntaub ntawv khaws cia hauv NAS ntev li ntev tau lawv tuaj yeem txuas nrog NAS. Koj tuaj yeem nkag ncaj qha rau NAS hauv xov tooj ntawm tes, laptops, ntsiav tshuaj, TVs ntse thiab lwm yam khoom siv, ib yam li siv cov ntaub ntawv hauv zos, siv cov ntaub ntawv khaws cia hauv NAS. NAS cov cuab yeej muaj txiaj ntsig ntawm qhov rov qab siv dua, uas tuaj yeem paub qhov txuas ntxiv ntawm chaw ua haujlwm hauv LAN. Ntawd yog hais, thaum cov ntaub ntawv khaws cia hauv tib lub computer ntawm tib LAN, nws tuaj yeem nyeem tau sai.
3. Luag Lub Chaw NAS muaj cov ntaub ntawv muaj zog thaub qab muaj nuj nqi. Piv nrog rau lwm lub network khaws cia, nws xyuas kom cov ntaub ntawv muaj kev ruaj ntseg. Vim tias qhov chaw taws teeb nkag mus, cov neeg siv tuaj yeem rov qab cov ntaub ntawv rau NAS lub sijhawm txhua lub sijhawm, thiab txawm tias cov khoom siv davhlau ya nyob twg tau ploj lossis puas ntsoog, cov ntaub ntawv yuav tsis ploj, kom ntseeg tau tias muaj kev ruaj ntseg ntawm cov ntaub ntawv.
Tus qauv khaws cia hauv network tuaj yeem sib faib ua peb hom: Direct Attached Storage (DAS), Network Daim Ntawv Txuas Cia (NAS) thiab Chaw Thaj Chaw Cia (SAN).
Hom tau tsam:
NAS yog daim phiaj disk txuas nrog los ntawm network cable, uas muaj tag nrho cov yam ntxwv tseem ceeb ntawm disk array: muaj peev xwm loj, ua haujlwm siab thiab ntseeg siab tau.
1.NAS yog yooj yim rau nruab thiab ceev
2. Yooj yim rau kev tswj
3. zoo heev scalability
4. Nws muaj cov lus teb tau nrawm dua thiab cov ntaub ntawv sib zog ntau dua
5. Txo cov kev xav tau ntawm tus neeg rau zaub mov tuaj yeem txo tus nqi ntawm tus neeg rau zaub mov, uas zoo rau kev nrov npe thiab kev siv cov khoom siv tau zoo.
system nyob rau hauv ib tug dav ntau
6. Txhawb nqa lub tshuab ua haujlwm sib txawv
Qhov tsis zoo:
1.NAS cov khoom siv thiab cov neeg siv tau sib txuas los ntawm cov qhauj network, yog li cov ntaub ntawv thaub qab lossis cia cov txheej txheem yuav nyob ntawm cov kab ke ntawm lub network. Qhov no yuav cuam tshuam uas cuam tshuam rau lwm cov kev siv network hauv cov lag luam sab hauv network; kev sib koom tes bandwidth ua lub ntsiab teeb meem txwv NAS kev ua tau zoo. Yog li no, cov ntaub ntawv xa mus kis ntawm NAS system tsis siab, thiab Gigabit Ethernet tsuas yog ncav cuag 30 ~ 50MB / s.
2.NAS scalability yog txwv los ntawm cov khoom siv me me. Nws yooj yim heev rau lwm qhov ntxiv rau NAS, tab sis nws tsis yooj yim los sib sau ua ke qhov chaw ntawm ob NAS khoom siv tau yooj yim, vim tias NAS cov khoom siv feem ntau muaj cov cim kev sib txuas hauv network, thiab kev nthuav dav ntawm qhov chaw cia tsawg. Nws tsuas yog muab cov chaw khaws ntaub ntawv thiab tsis tuaj yeem ua tiav raws li cov cai ntawm cov ntawv thov database.
3.NAS kev nkag mus yuav tsum tau ua cov qauv ntaub ntawv hloov dua siab tshiab, yog li nws tau nyob ntawm theem ntaub ntawv. Nws tsis haum rau cov qib thov qib, tshwj xeeb tshaj yog rau cov tshuab hlwb hlau uas xav tau cov khoom siv khoob.
4.Qhov tus nqi ntawm kev teeb tsa ntxov thiab khoom siv yog qhov siab.
Dab tsi xav tau los tsim kom tau 10 Gigabit NAS cia network?
Lub 10 Gigabit NAS cia lub network yog qhov tseem ceeb hauv cov khoom hauv qab no thiab cov khoom siv:
1. 10G Optical fiber network daim npav
10G fiber ntau daim npav network yog qhov tseem ceeb rau tsim 10 Gigabit NAS cia network. Yog li, nws yog qhov tsim nyog los xaiv qhov haum 10g NIC rau koj cov NAV ntim.
2. 10G network hloov
Hauv NAS cia network, 10G hloov network yog ib qho khoom nruab nrab los pab NAS cia thiab cov khoom siv davhlau ya nyob twg pom tau cov ntaub ntawv xa mus.
3. Cov khoom thauj kis tau tus mob: cov kab hluav taws xob fiber ntau cable thiab kho qhov muag
Thaum tsim lub 10 Gigabit NAS cia network, kom ntseeg tau tias lub tshuab xa khoom - cov hlua hluav taws xob thiab cov khoom siv hluav taws xob tau tshaj koj 10G network daim npav thiab 10g hloov. Raws li cov kev xav tau tiag tiag, koj tuaj yeem xaiv lub network jumper lossis fiber ntau jumper kom txuas cov sib hloov sib txuam thiab daim npav ua ke hauv lub network cia. Yog tias koj npaj tsim lub 10 Gigabit NAS cia network raws li cov kab hluav taws xob tooj liab uas twb muaj lawm, nws raug pom zoo kom koj siv CAT6 lossis cat6a network jumper ua tus xa cov khoom xa tuaj; yog tias koj cov cuab yeej yog SFP + 10g hloov lossis SMP + 10G daim npav network, koj yuav tsum siv cov fiber ntau jumper thiab 10G Optical module los txuas koj daim npav network thiab hloov. Yog tias qhov kis tau mus deb tsawg dua 10 Gigabit, koj kuj siv tau sf7 + hloov ncaj qha.
Yuav tsim li cas 10 Gigabit NAS cia network nrog kho qhov muag network?
