Intshayelelo
Kule minyaka yomsebenzi wam kwintsimi ye-IT kwaye ngokukodwa kwiintengiso ze-IT, ndibone iiprojekthi ezininzi zokulinga, kodwa ezininzi zazo ziphelile zingenanto kwaye zithatha ixesha elibalulekileyo.
Ngexesha elifanayo, ukuba sithetha ngokuvavanya izisombululo ze-hardware, ezifana neenkqubo zokugcina, kwi-demo nganye inkqubo ngokuqhelekileyo kukho uluhlu lokulinda malunga nonyaka ngaphambili. Kwaye lonke uvavanyo kwishedyuli lunokuzisa ukuthengiswa okanye, ngokuchaseneyo, bonakalise ukuthengiswa. Akukho sizathu sokuqwalasela imeko apho uvavanyo aluchaphazeli ukuthengisa, ekubeni uvavanyo nalo alunangqiqo - kukuchitha ixesha kunye nokuchitha ixesha kwinkqubo yedemo.
Ke, unokwenza njani yonke into ngobulumko kwaye wenze yonke into yenzeke?
Ukulungiselela
Iinjongo zomqhubi wenqwelomoya
Uqala phi umqhubi wenqwelo-moya? Akunjalo ngezixhobo zokudibanisa kwi-rack, akunjalo. Ngaphambi kokuba nawuphi na umsebenzi kwisixhobo uqalise, amaphepha ayenziwa. Kwaye siqala ngokuchaza iinjongo zomqhubi wenqwelomoya.
Injongo yomqhubi wenqwelomoya kukuphelisa inkcaso kumthengi wokugqibela. Akukho zichaso - akukho pilothi efunekayo. Ewe Ewe kanye.
Kodwa zeziphi iindidi eziphambili zenkcaso esinokuzibona?
* Siyathandabuza ukuthembeka
*Sinamathandabuzo malunga nokusebenza
* Siyathandabuza ukuqina
* Siyathandabuza ukuhambelana kunye nokukwazi ukusebenza kunye neenkqubo zethu
* Asikholelwa kwizilayidi zakho kwaye sifuna ukuqiniseka xa siqhuba ukuba inkqubo yakho inokwenza konke oku
* Konke oku kuya kuba nzima kakhulu, iinjineli zethu sele zixakekile kwaye kuya kuba nzima kubo
Lilonke, ekugqibeleni sifumana iintlobo ezintathu eziphambili zovavanyo lomqhubi kwaye, njengemeko ekhethekileyo yomqhubi, ubungqina bengcamango (i-PoC - ubungqina bengcamango):
* Uvavanyo lomthwalo (+ scalability)
* Uvavanyo olusebenzayo
* Uvavanyo lokunyamezela impazamo
Kwimeko ethile, kuxhomekeke kumathandabuzo omthengi othile, umqhubi we-pilot unokudibanisa iinjongo ezahlukeneyo, okanye, ngokuchaseneyo, omnye wabo unokuba khona.
Umqhubi wenqwelomoya uqala ngoxwebhu oluchaza ngesiRashiya esicacileyo isizathu sokuba olu vavanyo lwenziwa. Kukwabandakanya neseti yeenqobo ezilinganisekayo ezenza kube lula ukutsho ngokungafihlisiyo ukuba ngaba umqhubi wenqwelomoya uphumelele ngempumelelo okanye yintoni kanye kanye engakhange ipasiswe. Iikhrayitheriya ezinokulinganiswa zinokuba ngamanani (ezifana nokubambezeleka kwi-ms, IOPS) okanye i-binary (ewe/hayi). Ukuba umqhubi wenqwelo-moya wakho unexabiso elingenakulinganiswa njengekhrayitheriya, akukho njongo kumqhubi wenqwelo-moya, sisixhobo sokukhohlisa kuphela.
Izixhobo
Ulingo lunokuqhutywa kwizixhobo zedemo zomthengisi/umhambisi/iqabane okanye kwizixhobo zabathengi. Ukuthetha ngokuthe ngqo, umehluko uncinci, indlela eqhelekileyo iyafana.
Owona mbuzo uphambili malunga nezixhobo PHAMBI kokuba umqhubi aqale kukuba ingaba iseti epheleleyo yesixhobo ikhona (kubandakanywa iiswitshi, iintambo zedatha, iintambo zombane)? Ngaba izixhobo zilungele ukuvavanywa (iinguqulelo ze-firmware ezichanekileyo, yonke into ixhaswa, zonke izibane ziluhlaza)?
Ukulandelelana okuchanekileyo kwezenzo emva kokumisela iinjongo zokuvavanya kukulungiselela ngokupheleleyo izixhobo zokuvavanya PHAMBI kokuba zinikezelwe kumthengi. Ewe kunjalo, kukho abathengi abathembekileyo ngaphandle kokungxama, kodwa oku kuhlukile. Ezo. isethi epheleleyo kufuneka ihlanganiswe kwindawo yeqabane, yonke into ihlolwe kwaye ihlanganiswe. Inkqubo kufuneka isebenze kwaye kufuneka uqinisekise ukuba yonke into iyasebenza, isoftware isasazwa ngaphandle kweempazamo, njl. Kuya kubonakala kungekho nto inzima, kodwa aba-3 kwaba-4 abaqhubi baqala ngokujonga iintambo okanye ii-transceivers ze-SFP.
Ngokwahlukileyo, kufuneka kugxininiswe ukuba njengenxalenye yokujonga inkqubo yedemo, kufuneka uqiniseke ukuba icocekile. Yonke idatha yovavanyo lwangaphambili kufuneka icinywe kwisistim ngaphambi kokudluliselwa. Kungenzeka ukuba uvavanyo lwenziwe kwidatha yangempela, kwaye kunokubakho nantoni na apho, kubandakanywa iimfihlo zorhwebo kunye neenkcukacha zomntu.
Inkqubo yovavanyo
Ngaphambi kokuba izixhobo zidluliselwe kumthengi, inkqubo yokuvavanya kufuneka ilungiswe ehlangabezana neenjongo zokuvavanya. Uvavanyo ngalunye kufuneka lube nesiphumo esinokulinganiswa kunye neendlela ezicacileyo zokuphumelela.
Inkqubo yokuvavanya inokulungiswa ngumthengisi, iqabane, umthengi, okanye ngokudibeneyo - kodwa rhoqo PHAMBI kokuqala kweemvavanyo. Kwaye umthengi kufuneka asayine ukuba wanelisekile yile nkqubo.
Abantu
Njengenxalenye yokulungiselela umqhubi, kuyimfuneko ukuvumelana ngemihla yomqhubi kunye nobukho babo bonke abantu abayimfuneko kunye nokulungela kwabo ukuvavanywa, zombini kwicala lomthengisi / iqabane kunye nenxalenye yomthengi. Owu, bangaphi abaqhubi beenqwelo-moya abaqalayo nomntu oyintloko kumqhubi womthengi ukuya ekhefini ngosuku emva kokufakwa kwezixhobo!
Imimandla yoxanduva/yokufikelela
Inkqubo yokulinga kufuneka iqonde ngokucacileyo kwaye ichaze ngokucacileyo uxanduva lwabo bonke abantu ababandakanyekayo. Ukuba kuyimfuneko, ukufikelela kude okanye ngokomzimba komthengisi / iinjineli zeqabane kwiinkqubo zomthengi kunye nedatha ilungelelaniswe nenkonzo yokhuseleko lomthengi.
Umqhubi wenqwelomoya
Ukuba sigqibe onke amanqaku angaphambili, ke eyona nto ikruqulayo ngumqhubi wenqwelomoya ngokwakhe. Kodwa kufuneka ibaleke ngokungathi ikwiziporo. Ukuba akunjalo, ngoko ke inxalenye yolungiselelo yajijwa.
Ukugqitywa kolingelo
Ekugqityweni kolingelo, uxwebhu luyalungiswa ngovavanyo olwenziweyo. Ngokufanelekileyo, kunye nazo zonke iimvavanyo kwiprogram enophawu lokutshekisha lwePASS eluhlaza. Kunokwenzeka ukuba ulungiselele umboniso kubaphathi abaphezulu ukwenza isigqibo esifanelekileyo ekuthengeni okanye ukubandakanywa kuluhlu lweenkqubo ezivunyiweyo zokuthengwa.
Ukuba awunalo uxwebhu ezandleni zakho ekupheleni kovavanyo kunye noluhlu lweemvavanyo ezigqityiweyo kunye namanqaku aphumeleleyo, umqhubi we-pilot akaphumelelanga kwaye akufanelekanga ukuba aqaliswe konke.
