RAID
Intego yibanze ya RAID nugutanga ubushobozi bwo murwego rwohejuru rwo kubika hamwe namakuru yumutekano arenze kuri seriveri nini. Muri sisitemu, RAID igaragara nkigice cyumvikana, ariko igizwe na disiki nyinshi zikomeye (byibuze ebyiri). Itezimbere cyane amakuru yinjira muri sisitemu yo kubika icyarimwe kubika no kugarura amakuru muri disiki nyinshi. Iboneza byinshi bya RAID bifite ingamba zuzuye zo kugenzura / kugarura, harimo no kugaragariza indorerwamo. Ibi byongera cyane kwihanganira amakosa ya sisitemu ya RAID kandi bitezimbere sisitemu ihamye no kugabanuka, niyo mpamvu ijambo "Kurengana."
RAID yahoze ari ibicuruzwa byihariye muri domaine ya SCSI, bigarukira ku ikoranabuhanga ryayo ndetse nigiciro cyayo, byadindije iterambere ryayo ku isoko ryo hasi. Uyu munsi, hamwe no gukura kwiterambere rya tekinoroji ya RAID nimbaraga zihoraho zakozwe nababikora, abashinzwe ububiko barashobora kwishimira cyane sisitemu IDE-RAID ihendutse cyane. Nubwo IDE-RAID idashobora guhura na SCSI-RAID mubijyanye no gutekana no kwizerwa, ibyiza byayo mumikorere ya disiki imwe irashimishije cyane kubakoresha benshi. Mubyukuri, kubikorwa bya buri munsi buke-buke, IDE-RAID irarenze ubushobozi.
Bisa na modem, RAID irashobora gushyirwa mubikorwa nka software yuzuye, igice cya software / igice-cyuma, cyangwa ibyuma byuzuye. Porogaramu yuzuye RAID bivuga RAID aho imikorere yose ikemurwa na sisitemu y'imikorere (OS) na CPU, nta muntu uwo ari we wese ugenzura / gutunganya (bakunze kwita RAID co-processor) cyangwa chip ya I / O. Muri iki kibazo, imirimo yose ijyanye na RAID ikorwa na CPU, bikavamo imikorere mike muburyo bwa RAID. Semi-software / igice-ibyuma RAID ibura cyane cyane chip yo gutunganya I / O, bityo CPU na progaramu ya shoferi bashinzwe iyi mirimo. Byongeye kandi, imiyoboro ya RAID igenzura / gutunganya ikoreshwa muri kimwe cya kabiri cya software / igice cya kabiri cya RAID muri rusange ifite ubushobozi buke kandi ntishobora gushyigikira urwego rwo hejuru rwa RAID. Ibyuma byuzuye RAID ikubiyemo RAID igenzura / gutunganya hamwe na chip yo gutunganya I / O, ndetse ikubiyemo na buffer array (Array Buffer). Itanga imikorere myiza muri rusange hamwe na CPU ikoreshwa muri ubu bwoko butatu, ariko ikazana nigiciro kinini cyibikoresho. Ikarita ya IDE RAID yambere hamwe na kibaho cyababyeyi ukoresheje HighPoint HPT 368, 370, na chip ya PROMISE byafatwaga nkigice cya software / kimwe cya kabiri cyuma RAID, kuko cyabuze gutunganya I / O. Byongeye kandi, imiyoboro ya RAID igenzura / itunganya ibicuruzwa biva muri ibyo bigo byombi yari ifite ubushobozi buke kandi ntishobora gukora imirimo itoroshye yo gutunganya, bityo ntishyigikire urwego rwa RAID 5.Urugero rugaragara rwibikoresho byuzuye RAID ni ikarita ya AAA-UDMA RAID yakozwe na Adaptec. Igaragaza urwego rwohejuru rwihariye rwa RAID hamwe na Intel 960 yihariye I / O itunganya, ishyigikira byimazeyo urwego rwa RAID 5. Igaragaza ibicuruzwa byateye imbere IDE-RAID iboneka ubu. Imbonerahamwe 1 igereranya software isanzwe RAID hamwe nibikoresho bya RAID mubikorwa byinganda.
