Disk azinazo RAID: ntoni na nokuba kutheni kubalulekile?

abasebenzisi abaninzi baye weva into enjalo njengoko RAID kwimiboniso kwidiski, kodwa kusenziwa bambalwa kakhulu abantu ngoku ukucinga ukuba yintoni na. Kodwa njengoko kuvela, akukho nto esintsonkothileyo apha. Makhe sihlolisise kakuhle eli gama, oko kukuthi, phezu iminwe, ngokusekelwe ulwazi ingcaciso kuthelekiswa nommi.

Yintoni ma idiski RAID?

Okokuqala, cinga unyango ngokubanzi olunikwayo iimpapasho online. Azinazo Disk - inkqubo yokugcina yonke, kuqulethe inyanda ezimbini okanye ngaphezulu drives hard, abasebenzi, okanye ukunyusa isantya lokufikelela kulwazi olugcinwe, okanye ngenxa phindwa, umzekelo, xa ugcine iikopi zeenkcukacha.

Kule mali ngokubambisana yokumkisa ngokwemiqathango yofakelo isondlo akanayo izithintelo. konke kuxhomekeke kwinani kokufakelwa axhaswa motherboard. Eneneni, kutheni kusetyenziswa kwimiboniso idiski RAID? Kubalulekile ukuqaphela ukuba ngakwicala lophuhliso technology (ngokuphathelele drives ezizezi nzima), baye kudala emkhenkceni ngaxa lithile (edibanise isantya ka 7200 rpm. / Min, ubungakanani cache, njalo njalo. D.). Okungaphandle kulo mba Akayomizekelo SSD kuphela, kodwa ukwandisa kuphela ngobuninzi obuvelisiweyo ikakhulu. Ngelo xesha ekuvelisweni iziqhubekisi okanye neeplanga RAM phambili obuphathekayo. Ngaloo ndlela, ukusetyenziswa RAID-kwimiboniso ikhutshwa Ukukhula ukwanda xa ungena kwi hard disk.

Azinazo Disk RAID: iintlobo, injongo

Ke kwimiboniso ngokwabo, ukuba zibe phantsi kwemiqathango ethile lahlulwe yokunombola esetyenzisiweyo (0, 1, 2, njalo njalo. D.). inombolo ngamnye ingqinelana ukuya ekuphunyezweni omnye wale misebenzi ibango.

Eyona iphambili kule yokuhlela ezi kwimiboniso disk kunye amanani 0 no-1 (emva koku, kuya kuqondwa kutheni), kuba wabelwe kubo ingxaki enkulu.

Xa ukwenza lens kunye drives ngaphezulu elidityaniswe ekuqaleni ukusebenzisa setup BIOS, apho icandelo wada wabiliswa uphela RAID uqwalaselo, wabeka ixabiso. Kubalulekile ukuqaphela ukuba drives ezidityanisiweyo kufuneka zifane parameters ngokwemiqathango umthamo, interface, uqhagamsheleko, cache, njalo-njalo. D.

RAID 0 (Striping)

Zero ma disk ukulunga zenzelwe ukuba bakhawulezise ukufikelela data egcinwa (ukubhala okanye ukufunda). Baya kudla banokuba ngokubambisana drives ezimbini ukuya kwezine.

Kodwa apha ingxaki enkulu kukuba xa ucima data kwi diski, iyalahleka, kunye nabanye. Ulwazi oluthile lurekhodwa ineebloko khosi kwidiski nganye, kwaye ukunyuka komsebenzi kisekiyo ngqo inani drives (oko kukuthi, idiski ezine kabini ngokukhawuleza kangangoko ezimbini). Kodwa nantsi ukulahleka kwengcaciso kunxulumene kuphela yokuba iiyunithi ibe drives ezahlukeneyo, nangona umsebenzisi i "Explorer," ukubona iifayile kwi ukubonisa yesiqhelo.

RAID 1

ma Disk kunye nokonyulwa olunye kuba kudidi Ibukusa (zibonise), nikhonze ukuba asindise kunale data.

Lwaba ethetha, kwimeko enjalo umsebenzisi ulahlekelwa intsebenzo ethile, kodwa kunokuba kuhle ukuba kunye yokuduka data ukusuka kwicandelo elinye, ziya kugcinwa kwenye.

RAID 2 nangaphezulu

Ma amanani 2 ngasentla nenjongo ezimbini. Kwelinye icala, ukuba yenzelwe ukuba ubhale ingcaciso kwelinye - zisetyenziselwa ukulungisa impazamo.

Ngamanye amazwi, le hlobo kwimiboniso zokugcina oludibanisa izakhono RAID 0 kunye RAID 1, kodwa abasebenzisi phakathi ikhompyutha akumnandanga ithandwa enkulu, nangona isiseko umsebenzi wabo ukusetyenziswa ikhowudi Hamming.

Yintoni kungcono ukuba ukusebenzisa practice?

Kakade ke, ukuba ikhompyutha yakho ibimele ukuba asebenzise iinkqubo resource-olunzulu, ezifana nemidlalo mihla, kubhetele ukusebenzisa lens RAID 0. Ukuba usebenza inkcazelo ebalulekileyo ekufuneka zigcinwe nangayiphi na indlela, kuya kufuneka ukuba isicelo kwimiboniso RAID 1. Ngenxa yokuba iqelana lamanani ezimbini okanye ethandwayo okanye akazange, ukusetyenziswa kwazo kuxhomekeke kuphela ngumsebenzisi. Hi ndlela leyi, ukusetyenziswa uluhlu null kuyasebenza kwaye ke xa kunokwenzeka ukuba umsebenzisi rhoqo usindanisa iifayile yemultimedia kwi khompyutha, nithi, iimovie okanye umculo bitrate eliphezulu i MP3 okanye FLAC umgangatho.

Xa abanye kuya kufuneka sithembele ukhetho lwabo kunye neemfuno. Ivela koku kwaye kuya kuxhomekeka nokusetyenziswa uluhlu ethile. Kakade, xa ucwangcisa Umatshini kungcono ukunika kuqala disks SSD xa kuthelekiswa kulimo hard diski drives sele ekuqaleni ukurekhodwa ephakamileyo isantya sokufunda. Kodwa kufuneka kufana twatse ngokugqithisileyo iimpawu zazo kunye parameters, okanye indibanisela lokujikeleza ekhohlo nje akuyi kusebenza. Kwaye le yenye yezona meko ibalulekileyo. Ngoko kuyimfuneko ukuba ziwuthathele ingqalelo lo mba.
