Sena se lumella mekhatlo ho eketsa bokhoni ba eona ba polokelo ntle le ho reka le ho boloka li-server tse theko e boima.

Mokhoa o mong oa bohlokoa ke ts'ebetsong ea meralo ea li-software-defined storage (SDS). Sena se kenyelletsa ho arola software ho hardware ho li-server tsa polokelo, ho lumella ho fetoha ha maemo ho laola le ho lokisa mehloli ea polokelo. SDS e boetse e thusa ho kopanngoa ha mefuta e fapaneng ea polokelo, joalo ka li-hard disk drive, solid-state drives, le polokelo ea leru, ho ba meaho e le 'ngoe.

Ka mokhoa o ts'oanang, litharollo tsa polokelo ea data li ntse li tsoela pele mabapi le ts'ebeliso ea litsamaiso tsa lifaele tse ajoang. Litsamaiso tsena li lumella ho laola lintlha tse ngata tse ajoang ho li-server tse ngata, ho ntlafatsa ho fokotseha ha data le ho fumaneha. Mehlala e meng ea litsamaiso tsa lifaele tse ajoang tse tsebahalang li kenyelletsa Hadoop Distributed File System (HDFS) le GlusterFS. Litsamaiso tsena tsa lifaele tse ajoang li sebelisa mokhoa o thehiloeng ho thibela ho arola hantle le ho boloka data ho pholletsa le li-server tse fapaneng.

10. Mokhoa oa ho khetha seva e nepahetseng ea polokelo ea data bakeng sa khoebo ea hau

Ha u khetha seva e nepahetseng ea polokelo ea data bakeng sa khoebo ea hau, ho bohlokoa ho nahana ka lintlha tse 'maloa tsa bohlokoa. Taba ea pele, ho bohlokoa ho lekola litlhoko tsa polokelo tsa k'hamphani ea hau hajoale le tsa nakong e tlang.

14. Bokamoso ba li-server tsa polokelo ea data: tsoelo-pele ea theknoloji

Tsoelo-pele ea theknoloji ho li-server tsa polokelo ea boitsebiso e fetotse tsela eo re laolang le ho boloka boitsebiso ka eona. Ho fetoha ha li-server ho entse hore ho be le keketseho e kholo ea bokhoni ba polokelo, hammoho le phihlello ea data e potlakileng le e sebetsang haholoanyane.

E 'ngoe ea likhatelo-pele tse hlokomelehang nakong e tlang ea li-server tsa polokelo ea data ke ts'ebetsong ea mekhoa e sa fetoheng ea polokelo, joalo ka li-drive tse tiileng (SSD) le memori ea flash. Litheknoloji tsena li fana ka linako tsa phihlello tse potlakileng le ho tšoarella ho hoholo ha li bapisoa le li-hard drive tsa setso.

Ho feta moo, li-server tsa polokelo ea data li lebelletsoe ho amohela theknoloji ea polokelo ea leru ka bophara. Sena se tla lumella lintlha tse ngata ho fihlella le ho bolokoa hole, ho nolofatsa tšebelisano 'moho le ho arolelana tlhahisoleseling ka nako ea nnete. Leru le boetse le fana ka phetoho e kholoanyane le scalability, ho lumella sebaka sa polokelo hore se lokisoe ha litlhoko tsa polokelo li fetoha. Ka bokhutšoanyane, bokamoso ba li-server tsa polokelo ea data bo re fa bokhoni bo boholo, lebelo, le ho fetoha ha maemo taolong ea tlhahisoleseling.

Ka bokhutšoanyane, li-server tsa polokelo ea data ke lisebelisoa tsa hardware tse etselitsoeng ho boloka boitsebiso bo bongata ka mokhoa o sireletsehileng le habonolo. Li-server tsena li bohlokoa bakeng sa likhoebo le mekhatlo e hlokang ho laola le ho boloka lintlha hantle. Ba fana ka matla a polokelo a hlokahalang ho sebetsana le boitsebiso bo bongata le ho fana ka lisebelisoa tse ka tšeptjoang ho tšehetsa mesebetsi ea khoebo.

Li-server tsa polokelo ea data li sebelisa mahlale a tsoetseng pele joalo ka RAID (Redundant Array of Independent Disks) ho netefatsa botšepehi ba data le ho sireletsa khahlanong le liphoso tse ka bang teng. Li boetse li fana ka likarolo tse kang redundancy, scalability, le ho fumaneha ho phahameng ho finyella litlhoko tsa kajeno tsa polokelo ea data.

Ka kholo e tsoelang pele ea Big Data le tlhokahalo e ntseng e eketseha ea polokelo, Li-server tsa polokelo ea data li fetohile karolo ea bohlokoa ea lisebelisoa tsa theknoloji. Li lumella mekhatlo ho laola le ho fumana boitsebiso bo bongata ka botšepehi le ka katleho.

Qetellong, Li-server tsa polokelo ea data ke lisebelisoa tsa bohlokoa ho netefatsa polokelo e bolokehileng ebile e ka tšeptjoa ea data libakeng tsa khoebo. Bokhoni ba bona ba ho fana ka bokhoni bo boholo ba polokelo, ts'ireletso ea data, le scalability li ba etsa khetho ea bohlokoa bakeng sa k'hamphani efe kapa efe e batlang ho laola le ho sebelisa lintlha tsa bona tsa bohlokoa ka botlalo.
