- Ukuhlaziywa kokwakhiwa kwesilawuli esisebenzayo esikabili ukuqinisekisa ukuqhubeka kwesevisi okungaphazanyiswa.
- Ukusetshenziswa kobuchwepheshe be-NVMe bonke ukuze kukhuliswe i-IOPS futhi kuncishiswe ukubambezeleka ezindaweni ezibalulekile emsebenzini.
- Amasu okuthuthukisa idatha asebenzisa izinhlelo zamafayela ze-Btrfs zesizukulwane esilandelayo kanye nokudluliselwa kwedatha okuthuthukisiwe.
Uma sikhuluma ngengqalasizinda yesimanje yezobuchwepheshe, isivinini asiseyona into eza kuqala; manje okubaluleke kakhulu ukuthi uhlelo alunciphi ngisho nomzuzwana . Kulesi simo, isitoreji se-NVMe esinezakhiwo ezisebenzayo sesibe yitshe eliyigugu kulezo zinkampani ezingakwazi ukukhokhela izinsizakalo zazo ukuthi zime ngenxa yokwehluleka kobuchwepheshe.
Ngokungafani nezinhlelo zendabuko, lapho omunye umlawuli elala khona ngenkathi omunye esebenza, lapha sinesistimu lapho womabili amaprosesa esebenza khona ngesikhathi esisodwa. Lokhu akuyona nje intuthuko yezobuchwepheshe, kodwa ushintsho oluhambisana nombono oluvumela ukuphathwa kwemininingwane eminingi ngendlela emangalisayo, efanele labo abaphatha izizindalwazi zokuthengiselana noma izindawo ezisindayo ze-virtualization.
Ukwakhiwa Okusebenzayo: Ngale Kokuphindaphindwa Okulula
Ezweni lesitoreji sebhizinisi, umqondo we-active-active usho ukuthi bobabili abalawuli baphatha izicelo zokufaka nezokukhipha ngesikhathi esisodwa. Uma eyodwa yehluleka, enye imunca ngokushesha ithrafikhi ngaphandle kokuthi umsebenzisi aqaphele lutho. Ukuqinisekisa ukuthembeka, kusetshenziswa izendlalelo eziqinile zokuvikela, njenge-triple parity RAID (RAID-TP), esebenza njengesivikelo ekulahlekelweni kwamadiski amaningi ezinhlelweni ezinabantu abaningi.
Iphuzu elibalulekile ukusetshenziswa kwebhuloho elingafihli lutho (i-NTB). Le ngxenye yehadiwe ivumela ukubhala kwememori ukuthi kuvumelaniswe ngesivinini esigcwele phakathi kwabalawuli. Ngaphandle kwayo, uma isilawuli esisodwa sihluleka ngokuzumayo, ungaba nedatha engaguquki noma eyonakele, okungaba yinhlekelele yangempela enkampanini yezinsizakalo zezezimali noma yezempilo.
Ngaphezu kwalokho, ukuze kwenziwe ukuphatha kube lula, kufakwe amachweba okuphatha angaphandle kwebhendi (OOB). Empeleni, lesi isiteshi sokuxhumana esizimele esivumela ochwepheshe ukuthi bafinyelele futhi baphathe imishini bekude noma ngabe inethiwekhi yedatha eyinhloko yonakele noma iphansi, ngaleyo ndlela bagweme ukuya esikhungweni sedatha ngokungadingekile.
Ukugxuma ku-All-NVMe kanye nokusebenza okudlulele
Iphrothokholi ye-NVMe iqede zonke izithiyo, yasusa izithiyo ezibangelwa ama-hard drive amadala noma ngisho nama-SATA SSD. Ngokusekela lonke uhlelo kumemori yesivinini esiphezulu, ehlala njalo , ifinyelela izibalo ezimangalisayo, ifinyelela ku-IOPS eyizigidi ezimbili kanye nokusebenza okulandelanayo okusondela ku-30 GB/s.
Lawa mandla awusizo kakhulu kwisitoreji esiyinhloko sendawo. Kungakhathaliseki ukuthi udinga i-SAN yamabhulokhi noma i-NAS yamafayela, ukuhlanganisa kokubili epulatifomu eyodwa kwenza kube lula ukusebenza, yize kudinga umphathi we-IT ukuthi alinganise ngokucophelela izinsiza ukuqinisekisa ukuthi amaphethini okufinyelela ahlukene awangqubuzani.
Ukuze kuvinjelwe ukulungiswa kungabi yikhanda elibuhlungu, amathuluzi afana ne-Continuous Availability Manager avumela i-firmware kanye nezibuyekezo zesofthiwe ukuthi zenziwe ngaphandle kwesikhathi sokungasebenzi . Lokhu kumnandi ezindlebeni zanoma yimuphi u-CIO, njengoba amafasitela okulungisa eyeka ukuba yiphupho elibi kakhulu lezokuthutha.
Ukusebenza kahle kwesikhala kanye nokunciphisa izindleko
Ukuba namandla amaningi okucubungula akusizi ngalutho uma isitoreji sigcwala ngokuphazima kweso. Yingakho ukudluliselwa okuthuthukisiwe kubalulekile. Ngokusebenzisa izinhlelo zamafayela ze-Btrfs zesizukulwane sakamuva, ungafinyelela isilinganiso sokunciphisa idatha esingu-5:1 . Lokhu kusho ukuthi ungaguqula umthamo ongahluziwe ube umthamo omkhulu osebenzayo, ofinyelela ku-8,25 PB kwezinye izimo.
Kunezindlela ezimbili zokubhekana nale nkinga: ukudluliselwa kwedatha okuqondile, okuhlanza idatha ngaphambi kokuyibhala, kanye nokucubungula idatha ngemva kwalokho, okwenza lokho kamuva. Lokhu kuhlanganiswa kusiza ukwehlisa izindleko eziphelele zobunikazi (TCO) ngokuthuthukisa isikhala se-rack kanye nokusetshenziswa kwamandla kwamamojula e-flash.
Ngaphezu kwalokho, ukufaka amazinga okuzenzakalelayo kuyisisombululo esihlakaniphile sedatha engasasetshenziswa njalo. Uhlelo luhambisa idatha engasetshenziswa kakhulu iye kuma-tier ashibhile , okushiya isitoreji se-NVMe esibizayo nesisheshayo kuphela sezinhlelo zokusebenza ezisebenza ngokugcwele ngesikhathi sangempela.
Ukuvikelwa kwedatha kanye nokuphepha okuhlanganisiwe
Ezweni lapho ukuhlaselwa kwe-ransomware kuyinto evamile, akwanele ukuthi uhlelo lusheshe; kumele luqiniswe. Ukusebenzisa ama-drive okuzibethela (ama-SED) kanye nokubethela okugcwele kuqinisekisa ukuthi idatha ephumulile ivikelwe ekufinyeleleni okungagunyaziwe.
Ngakolunye uhlangothi, ubuchwepheshe be-WORM (Write-Once Read-Many) kanye nezithombe ezingaguquki ziyizindlela zokugcina zokuzivikela. Lezi zici zivimbela idatha ukuthi isuswe noma iguqulwe ngendlela enonya, okuvumela izinkampani ukuthi zithole ulwazi lwazo ngokushesha futhi zinciphise i-RPO (Return on Perception) ibe ngamazinga amancane.
Ukuhlanganiswa kwamafu kanye nokwenza kube ngokoqobo
Asikwazi ukukhohlwa indawo yamafu, lapho i-Azure ihlanganise khona ukwesekwa kwe-NVMe ukuthuthukisa imishini yayo ebonakalayo. Ukushintsha kusuka ku-SCSI kuya ku-NVMe kuma-VM esizukulwane esilandelayo kuvumela amaseva ewebhu nezinhlelo zokusebenza zokuhlaziya ukucubungula ulwazi ngokubambezeleka okuphansi kakhulu.
Ngenxa yezinto ezintsha ezifana ne-Azure Boost, izinqubo ze-virtualization zisuswa ku-hypervisor ziye ku-hardware ezinikele. Lokhu kwenza ukusebenza kwamadiski aphethwe kube lula kakhulu, uma nje kusetshenziswa izithombe zesistimu yokusebenza ezihambisanayo kanye nemishini ebonakalayo ye-Generation 2.
Kulabo abasebenzisa izinhlelo ezindala noma zasekhaya, kunezindlela zomugqa womyalo (SSH) zokuzama ukumisa ama-NVMe SSD njengamavolumu esitoreji esikhundleni sezinqolobane ezilula, yize lokhu kunezingozi futhi kudinga ulwazi oluthuthukisiwe lokuhlukanisa kanye nokuphathwa kwe-RAID kusetshenziswa i-mdadm ezindaweni ze-Linux.
Ukuhlangana kokwakhiwa okusebenzayo, isitoreji se-flash yonke, kanye nezendlalelo zokuphepha ezingaguquki kuchaza inkathi entsha yengqalasizinda yedatha, okuvumela izinhlangano ukuthi zikhulise imisebenzi yazo ngaphandle kokwesaba ukwehluleka kwehadiwe kanye nokwenza ngcono yonke i-euro etshalwe kumthamo osebenzayo kanye nokusebenza okuqhubekayo.
