Kuj sim ua tsis tiav-txiav ib lub hauv paus chaw nres tsheb thaum lub sijhawm hloov pauv hloov tshiab thiab paub meej tias cov ntawv cuam tshuam tuaj tos cov kev pab cuam los ntawm cov tsev nyob ib sab. Qhov no ua pov thawj tias 20% redundancy ua tau tiag tiag.
Thaum Tej Yam Tsis Zoo
Cov teeb meem no tshwm sim ntau zaus.
Cov ntawv tsis teb:yog tias LED tsis flashes, lub roj teeb tsis tau qhib ua haujlwm - rov ua dua qhov ua kom ua tiav. LED flashes tab sis tsis muaj kev hloov pauv txhais tau hais tias daim ntawv lo tej zaum yuav tawm ntawm qhov ntau. Ib nrab lossis garbled zaub hloov tshiab taw qhia rau RF cuam tshuam - sim sib txawv thiab yos hav zoov rau kev sib tw 2.4GHz qhov chaw. Cov ntsiab lus qub uas yuav tsis hloov tshiab yog yuav luag ib txwm muaj teeb meem hauv kev tswj hwm software.
Base chaw nres tsheb teeb meem:tsis muaj hwj chim LED txhais tau tias PoE tsis sib tham -xyuas qhov chaw nres nkoj hloov tau txhawb PoE + thiab xyuas cov cable txiav. Lub hwj chim tab sis tsis muaj kev sau npe software yog kev teeb tsa hauv lub network - IP assignment, firewall rules, VLAN settings. Kev tsis sib haum xeeb nyob rau hauv ib cheeb tsam qhia txog kev tiv thaiv ciam teb los ntawm lub hauv paus chaw nres tsheb. Tag nrho cov ntawv nyob rau hauv ib cheeb tsam ua tsis tau ib txhij feem ntau txhais tau hais tias lub hauv paus chaw nres tsheb nws tus kheej tuag.
System- theem teeb meem:kev hloov tshiab queuing tab sis tsis ncav cov ntawv qhia txog kev sib txuas lus ntawm cov neeg rau zaub mov thiab cov chaw nres tsheb hauv paus - tshawb xyuas txoj hauv kev network thiab rov pib ESL cov kev pabcuam. Cov nqi tsis raug txawm hais tias qhov tseeb cov ntaub ntawv txhais tau hais tias kev sib koom ua ke synchronization tau tawg - khawb rau hauv API cav. Cov lus teb qeeb qeeb rau kev ua haujlwm ntawm cov ntaub ntawv, tshwj xeeb tshaj yog ntawm kev xa tawm loj dua. Disappearing bindings qhia cov ntaub ntawv kev noj nyiaj txiag - rov qab los ntawm kev thaub qab tam sim.
Cia Nws khiav
Tsis muaj kev saib xyuas thoob ntiaj teb, tab sis tsis quav ntsej qee yam ua rau muaj teeb meem.
Txhua hnubkev saib xyuas yuav tsum tau ua kom tiav los ntawm kev ceeb toom rau cov ntawv sau offline, roj teeb tsawg, thiab hloov kho tsis tau.Txhua lub lim tiam, tshuaj xyuas cov ntawv ceeb toom xwm txheej thiab tshawb xyuas txhua yam offline ntau tshaj ib hnub.Txhua hli, tshuaj xyuas cov ntawv hauv lub cev hauv thaj chaw muaj plua plav-cov chaw ua mov ci tsis muaj npe nrov-thiab qhov chaw- kuaj xyuas qhov tseeb.Txhua xyoo, tshuaj xyuas seb qhov kev hloov pauv hauv khw puas tau cuam tshuam cov chaw nres tsheb hauv paus thiab npaj hloov roj teeb.
Ntawm cov roj teeb: cov ntawv lo tsis yog cov neeg siv- tuaj yeem siv tau, yog li tag nrho lub tsev tau hloov pauv thaum lub roj teeb poob. Tsis txhob tos rau qhov ua tsis tiav. Thaum 10% ntawm lub nkoj qhia cov lus ceeb toom tsis tshua muaj roj teeb, tso qhov kev txiav txim hloov. Kev txiav txim thaum muaj xwm ceev raug nqi ntau dua thiab cov ntawv tuag thaum lub sij hawm tshaj tawm tsim teeb meem.
Deployment Scale
Kev xa me menyob rau hauv 500 daim ntawv lo xav tau 1-2 lub hauv paus chaw nres tsheb, ib hnub ntawm kev teeb tsa nrog ob tus neeg, thiab huab hosting. Cov phiaj xwm pib zoo rau pab pawg tshiab rau ESL.
Kev xa tawm nruab nrablos ntawm 500 mus rau 3,000 daim ntawv lo xav tau 3-8 lub hauv paus chaw nres tsheb, 2-4 hnub nrog 4-6 tus neeg pab pawg, thiab cov phiaj xwm tiag tiag.
Cov khw muag khoom lojnrog 3,000-15,000 daim ntawv lo txawv. Npaj rau 8-25 lub hauv paus chaw nres tsheb, 1-2 lub lis piam, pab pawg ntawm 8-12, thiab cov servers hauv tsev rau kev ntseeg tau. Kev xa mus rau theem thiab kev tswj xyuas qhov project yog qhov tsim nyog.
Enterprise scalesaum 15,000 daim ntawv lo-flagships, cov khw loj loj- txhais tau tias 25+ chaw nres tsheb hauv paus, 2-4 lub lis piam, 15+ pab pawg neeg uas muaj lub luag haujlwm tshwj xeeb, thiab rov ua dua tshiab. Tau txais kev pab cuam rau kev xa tawm thawj zaug ntawm qhov ntsuas no.
Quality Assurance Checklist
