Cov lus piav qhia luv luv ntawm cov khoom siv hluav taws xob rov ua dua
Cov khoom siv hluav taws xob rov ua dua yog hom hluav taws xob siv hauv lub network server. Nws yog tsim los ntawm ob lub zog tib yam khoom siv. Kev sib xyaw ic tswj cov khoom siv hluav taws xob los ua cov kev pabcuam hauv web. Thaum muaj teeb meem tshwm sim nyob rau hauv ib lub hwj chim mov, lwm lub hwj huam mov tuaj yeem ua haujlwm tam sim ntawd. Tom qab disassembled thiab txhim kho cov khoom siv fais fab, ob lub zog siv hluav taws xob sib koom ua ke. Cov khoom siv hluav taws xob rov ua dua yog txhawm rau txhim kho qhov scalability ntawm lub vev xaib server zoo dua. Ntxiv rau network servers, disk array system daim ntawv thov kuj muaj ntau heev.
RPS fais fab mov (RedundantPowerSystem, redundant fais fab system software) ua ib feem ntawm sab nraud DC fais fab mov ntawm lub network hloov
RPS tuaj yeem siv los ua pawg neeg rau zaub mov fais fab rau lub network hloov lossis xaim routers:
L Yog tias RPS thiab cov khoom siv hluav taws xob siv tib lub zog AC lub zog thiab kev faib khoom, thaum lub zog sab hauv ntawm cov khoom siv hluav taws xob pom qhov txawv txav, RPS tuaj yeem rov ua dua DC lub zog hluav taws xob rau cov khoom lag luam uas muaj teeb meem nyuaj los xyuas kom meej. kev ua haujlwm ib txwm muaj ntawm cov cuab yeej siv khoom lag luam;
L Yog tias RPS thiab cov khoom siv hluav taws xob siv cov khoom siv hluav taws xob sib txawv ntawm AC lub zog thiab kev xa tawm, nws kuj tuaj yeem muab cov khoom siv hluav taws xob DC rov qab thaum cov khoom siv hluav taws xob sab nraud AC fais fab mov ntawm cov khoom siv hluav taws xob ua rau muaj teeb meem nyuaj los xyuas kom meej tias cov khoom siv hluav taws xob sab nraud. tag nrho cov cuab yeej siv tshuab.
Dab tsi yog qhov khoom siv hluav taws xob rov ua dua? Qhov txawv ntawm ib qho khoom siv hluav taws xob rov qab thiab UPS fais fab mov?
Cov txheej txheem npaj uas tuaj yeem siv rau kev siv hluav taws xob rov ua dua feem ntau suav nrog ntim rov ua dua, rov ua dua qhov txias txias, sib piv tam sim no N+1 cov ntaub ntawv thaub qab cov ntaub ntawv, rov qab cov ntaub ntawv kub thaub qab thiab lwm txoj hauv kev. Volume redundancy txhais tau hais tias lub peev xwm loj heev ntawm cov khoom siv hluav taws xob ntau tshaj qhov tshwj xeeb load, uas tsis yog qhov tseem ceeb tshaj plaws rau kev txhim kho kev ruaj ntseg.
Rov qab rov qab txias txias txhais tau hais tias cov khoom siv hluav taws xob yog tsim los ntawm ntau cov tswj modules nrog tib txoj haujlwm. Thaum txhua yam zoo li qub, ib qho ntawm cov khoom siv hluav taws xob tau siv. Thaum nws ua tsis tiav, cov ntaub ntawv thaub qab module tuaj yeem khiav tam sim ntawd. Qhov tsis zoo ntawm hom no yog tias muaj lub sijhawm luv luv rau kev hloov pauv hluav taws xob, uas tuaj yeem yooj yim ua rau muaj qhov sib txawv ntawm qhov kev khiav hauj lwm voltage xav tau los ntawm kev ua haujlwm.
N+1 thaub qab nrog kev sib koom ua ke tam sim no txhais tau hais tias cov khoom siv hluav taws xob yog tsim los ntawm ntau cov qauv zoo ib yam, thiab txhua lub module txuas nrog rau tib lub sijhawm los ntawm OR diodes, thiab txhua lub module muab lub zog rau cov khoom siv hauv kev lag luam tib lub sijhawm. Cov tswv yim zoo li no tsis yooj yim rau kev puas tsuaj rau cov khoom siv hluav taws xob thaum lub zog hluav taws xob muaj teeb meem nyuaj, tab sis qhov cuam tshuam luv luv ntawm qhov kawg ntawm qhov kawg yog qhov yooj yim heev los cuam tshuam tag nrho cov modules. Rov qab kub rov qab txhais tau hais tias cov khoom siv hluav taws xob yog tsim los ntawm ntau lub modules thiab tuaj yeem ua haujlwm tib lub sijhawm, tab sis tsuas yog ib qho ntawm lawv muab lub zog rau cov khoom siv hauv kev lag luam, thiab lwm qhov yog khoob. Thaum muaj teeb meem nrog lub ntsiab fais fab mov, cov ntaub ntawv thaub qab tuaj yeem ua haujlwm tam sim ntawd, thiab cov zis hluav taws xob hloov pauv me me heev.
Rau qee qhov kev ua haujlwm tsis muaj kev cuam tshuam ntev li ntev tau, cov software txhim khu kev qha zoo, xws li kev sib txuas lus hauv chaw nres tsheb cov khoom siv, * cov khoom siv hauv kev lag luam, network servers, thiab lwm yam, feem ntau sim kom muaj cov khoom siv hluav taws xob zoo. Cov qauv tsim hluav taws xob rov ua dua tshiab yog qhov tseem ceeb ntawm no, thiab ua lub luag haujlwm tseem ceeb hauv kev nthuav dav software. Cov khoom siv hluav taws xob tsis zoo feem ntau yog nruab nrog ob lub zog siv hluav taws xob. Thaum cov khoom siv hluav taws xob ua rau muaj teeb meem nyuaj, lwm yam khoom siv hluav taws xob tuaj yeem muab tso rau hauv kev ua haujlwm tam sim ntawd, tsis tas yuav tsum nres tag nrho cov kev ua haujlwm ib txwm muaj ntawm cov khoom siv hauv kev lag luam. Qhov no zoo ib yam li lub tswv yim tseem ceeb ntawm UPS fais fab mov: thaum lub tshuab hluav taws xob ua haujlwm raug kaw, lub zog hluav taws xob tau hloov los ntawm lub roj teeb lithium rechargeable. Qhov sib txawv tseem ceeb ntawm cov khoom siv hluav taws xob rov qab thiab UPS yog tias nws tau siv los ntawm cov khoom siv hluav taws xob sib txawv tib lub sijhawm, thaum UPS yog lub zog siv hluav taws xob, thiab lwm qhov yog standby txhua lub sijhawm thiab nyob qhov twg, thiab nws yuav hloov pauv. thaum xav tau.
Ib txwm redundant fais fab txuas txuas
Cov qauv siv hluav taws xob siv hluav taws xob siv hluav taws xob tsim hluav taws xob yog tias ob lossis ntau lub zog siv hluav taws xob yog anodized raws li lawv cov kev sib txuas diodes, thiab tso tawm rau lub zog hluav taws xob lub tsheb npav nyob rau hauv ib qho" LOSSIS" txoj kev. Ib lub zog hluav taws xob tuaj yeem ua haujlwm ntawm nws tus kheej, thiab ntau lub zog hluav taws xob tuaj yeem ua haujlwm ua ke. Thaum ib qho ntawm cov khoom siv hluav taws xob ua rau muaj teeb meem nyuaj, nws tsis yooj yim rau kev puas tsuaj rau cov khoom siv hluav taws xob vim lub unidirectional conduction yam ntxwv ntawm lub diode.
Nyob rau hauv qhov tshwj xeeb redundant fais fab mov system software, qhov dav dav tam sim no kuj loj, uas tuaj yeem lav ntau ntau A. Kev xav txog tag nrho cov txiaj ntsig ntawm lub diode nws tus kheej, Schottky diodes nrog qis poob thiab tam sim no loj heev feem ntau siv, xws li SR1620 ~ SR1660 (nyob voltage 16A). Feem ntau, cov kav dej kub tau nruab rau ntawm hom diode no kom dissipate cua sov kom ntau li ntau tau.
Cov txheej txheem ib txwm siv ntawm diodes muaj lub zog hluav taws xob yooj yim, tab sis nws qhov kev tsis txaus siab: lub zog loj poob, kub hnyav, yuav tsum tau hloov cov kav dej kub kom dissipate cua sov, thiab tuav lub ntim loj. Vim tias lub zog hluav taws xob hluav taws xob feem ntau muaj ntau qhov tam sim no, lub diode yog nyob rau hauv hom kev coj mus rau pem hauv ntej feem ntau, thiab qhov ua tau zoo los ntawm nws qhov poob tsis tuaj yeem tsis quav ntsej. Schottky diode nrog qhov poob tsawg kawg kuj muaj 0.45V. Thaum qhov tam sim no loj, xws li 12A, yuav muaj lub zog poob ntawm 5W. Yog li ntawd, nws yog ib qho tsim nyog los daws qhov teeb meem ntawm kev tshem tawm cua sov.
Tam sim no txoj kev npaj siv hluav taws xob rov ua dua tshiab tam sim no yog siv lub zog MOSFETs los hloov cov diodes hauv cov khoom siv hluav taws xob ib txwm muaj. Lub on-off internal kuj ntawm MOSFET tuaj yeem ncav cuag ntau mΩ, uas txo qhov poob zoo heev. Hauv kev siv lub zog siab, tsis yog tsuas yog kev ua haujlwm siab ua tiav, tab sis kuj vim tias tsis tas yuav txuag cov yeeb nkab hluav taws xob hluav taws xob, ntau qhov chaw ntawm pcbpcb Circuit Court board tau txais kev cawmdim, thiab cov khoom siv cua sov ntawm cov khoom siv kuj raug txo. . Siv MOSFET nyob rau hauv lub hwj chim Circuit Court kom ntau li ntau tau kom muaj kev integrated ic manipulation.
