Ingabe i-multi-bay enclosure ingahlangabezana nezidingo zakho zendawo yokugcina yangaphandle ye-RAID?
Ukufakwa kwangaphandle kwe-RAID kuyindlela ethandwayo yokukhulisa amakhompyutha wakho isitoreji esitholakalayo ngenkathi ufaka ukwanda kokwenza noma ukuvikelwa kwedatha, noma kokubili. Iminye yemibuzo eyinhloko yokuphendula uma ufuna uhlelo lokugcina isitoreji se-RAID, imisebenzi ye-RAID izokwenziwa kanjani, ku-software noma nge-hardware ezinikezele.
Kungani i-RAID Inclosure yangaphandle?
Masibe sobala, uma injongo yakho eyinhloko kuphela yokwandisa inani lemishini yokushayela etholakalayo, ungathola idrayivu eyodwa yangaphandle ingaba inketho engabizi kakhulu. Ukushayela okukodwa kwangaphandle kuhambisana kakhulu; ingasetshenziselwa indawo yokugcina eyengeziwe, njengedrayivu yokusekelayo, noma ukufaka ezinye izinhlelo zokusebenza zokusebenza.
Ngaphandle kolunye uhlangothi, i-RAID esekelwe, izoklanywa ukuphatha amashayeli amaningi futhi unikeze umsebenzisi amandla okulungisa ukufakwa kokukodwa kokukodwa noma ngaphezulu kokulungiswa kwe-RAID.
Thola okuningi kulesi sihloko: Kuyini i-RAID?
Ukufakwa kwe-RAID kungalungiswa ukuze unikeze amazinga aphezulu okusebenza kunokuba atholakale avela kumashayeli angashadile, angakwazi futhi ukuhlinzekela ukulungiswa kwedatha, ukuqinisekisa ukuthi idatha yakho iyatholakala ngisho noma idrayivu ihluleka . Izinhlelo ze-RAID nazo zingalungiswa kokubili ukusebenza nokuvikelwa kwedatha.
I-Software noma i-Hardware Based RAID Controller
Inhliziyo yomsindo we-RAID ungumlawuli, owenza umyalo wokusabalalisa idatha futhi kusukela kumashayela akha i-RAID. Abalawuli be-RAID bangaba yi-hardware esekelwe, besebenzisa i-chip eyakhelwe ku-RAID enclosure, noma isofthiwe esekelwe, isebenzisa amandla e-computing ekhompyutheni yakho ukulawula ukuthi idatha ifundwa noma ibhalwa kanjani.
Ukuhlakanipha okujwayelekile kuye kwaba ukuthi abalawuli be-hardware-based basuke benenzuzo ekusebenzeni, bakwazi ukwenza izibalo ezidingekayo ukuze baqondise idatha kudatshulwa ku-RAID ngaphandle kokuletha ukungena kokusebenza. Amasistimu asekelwe kwi-software ngokuvamile ayabiza kakhulu futhi angenza ngokwanele amazinga amathathu we-RAID adumile, i- RAID 0 (i-Striped for speed) , i- RAID 1 (Idatha ehlanganisiwe ye-redundancy) , ne- RAID 10 (isethi esenzelwe ukushayela) . Kodwa bekunenkinga yokusebenza ngamazinga amaningi we-RAID.
Amazinga aphezulu we-RAID afana ne-RAID 3 no- RAID 5 avikela idatha ngokusebenzisa izibalo eziyinkimbinkimbi ukuze kuvezwe idatha yohlu ebhalwe phansi eceleni kwe-flow flow data ngesikhathi esisodwa kubhekwa njengengcindezi enkulu kumasistimu asekelwe kwesofthiwe futhi kwaholela ekunciphiseni amazinga okusebenza kunalokho okwabonwa ngabalawuli be-RAID asekelwe kwi-hardware.
Noma kunjalo, izinhlelo zokucubungula zanamuhla zisebenzisa ama-process cores amaningi, kanye nezinhlelo zokusebenza zanamuhla ezisebenzisekayo izinqubo eziyinhloko zezinhlelo zokusebenza zisuse kakhulu inhlawulo yokusebenza kumasistimu we-RAID-based, okungenani amazinga ayisisekelo we-RAID ka-0, 1, 3 , 5, no-10.
I-RAID ye-Software-Based
Amasistimu we-RAID asebenzisa ukulawulwa kwesofthiwe anezici ezilandelayo:
- Izindleko ezincishisiwe: Ngenxa yokuthi i-RAID enclosure ingasebenzisa ama-chipsets ejwayelekile, isiklamo nokukhiqiza kugcinwa phansi kwi-RAID enclosure. Izindleko zekhompyutha zingase zibe ziphansi njengezero, ngoba izinhlelo eziningi zokusebenza zihlanganisa ukwesekwa okwakhelwe ngaphakathi kumazinga ayisisekelo we-RAID ngokuvamile 0, 1, 10. Uma udinga i-RAID 3, noma i-5, kunezinhlelo zokusebenza zesofthiwe zendleko ezengeziwe ezingatholakala ukunakekela izidingo zakho.
- Ukungafani: Izilawuli ze-RAID ezisuselwe ku-Software zivumela ukuguquguquka okukhulu ekulungiseleleni ukuthi umshayeli ngamunye ngaphakathi kwesikhangiso uzosetshenziswa. Ngaphakathi kwendawo yokushayela emine; ungaba nezinqola ezintathu ezilungiselelwe njenge-striped umugqa wokusebenza, ne-1 enkulu drive yokusekela. Ungakwazi futhi ukulungisa amashayeli amane njengemigqa emibili emele, isethi emigqa yokuhlelwa kwevidiyo, kanye nesethi ehlanganisiwe yama-multimedia amatafula. Iphuzu lokuthi yilokho ukushayela okufakiwe okusetshenziselwa khona kuphelele kuwe.
- Ukusebenza: Amasistimu we-RAID asekelwe kwi-software asetshenziselwa izigcawu eziyisisekelo ezinemizila noma izigcawu ezihlanganisiwe azikwazi ukubona isijeziso sokusebenza . Noma kunjalo njengoba inani lezinjini ezisetshenziselwa ukukhula, noma amazinga we-RAID anzima kakhulu, izinhlelo zokusebenza ze-RAID ezisekelwe kwesofthiwe zingaqala ukuphazamisa ukusebenza kohlelo lwe-RAID, kanye nokusebenza jikelele kwekhompyutha.
- Ngaphezulu: I-RAID esekelwe kwi-Software isebenzisa i- CPU eyodwa noma ngaphezulu , kanye ne-RAM engathinta ezinye izinqubo eziqhutshwa kukhompyutha yakho. Ubukhulu bomthelela buncike ezingeni le-RAID elisetshenzisiwe, kanye nenombolo yamashayela akha i-RAID.
- I-Bootable: Lokhu kuyinkinga evumelanisiwe, isofthiwe esithile se-RAID isebenza kahle ngokubamba iqhaza ukusuka ku-RAID, futhi abanye banezinkinga. Uma izinhlelo zakho zibandakanya ukuthutha kusuka ohlwini lwakho lwe-RAID qinisekisa futhi uhlole ukuthi isofthiwe ye-RAID ohlela ukuyisebenzisa isekela ukuxhuma.
I-RAID eyakhiwe nge-Hardware
Ukufakwa kwe-RAID okusebenzisa isilawuli se-RAID esekelwe kwi-hardware sinemikhakha elandelayo:
- Izindleko: ukuvalwa kwe-RAID okusekelwe kwi-Hardware kuzothola ukukhokhelwa kwentengo uma kuqhathaniswa nezindawo eziningi zokungena nge-RAID ezakhiwe ngaphakathi. Noma kunjalo, umehluko entengo ingaba mncane. I-hardware eyisisekelo ye-RAID esekela kuphela ama-striped, ahlanganisiwe noma ahamba phambili ahamba phambili ane-premium yezindleko ezincane, kuyilapho abalawuli be-RAID basekelwe kwi-hardware abeseka amazinga we-RAID angeziwe kanye nokushayela okuningi ngaphakathi kwe-akhawunti kungase kube ne-premium yentengo enkulu.
- Ukuzibandakanya: Izinhlelo ze-RAID ezisuselwe ku-Hardware zibonakala ohlelweni lokusebenza lokusingathwa njengediski elilodwa. Lokhu kuvumela uhlelo lwe-RAID ukuthi lubonakale kukhompyutha oluxhunyiwe kuyo. I-upshot yizinhlelo ze-RAID ezisekelwe kwi-hardware zithuthwa kalula phakathi kwamakhompyutha nezinhlelo zokusebenza.
- Ukusebenza: Nakuba i-RAID yesofthiwe neye-hardware ingaba nezinombolo ezifanayo zokusebenza zamazinga ayisisekelo abanjwe emigqagqabeni, uma uhambela emazingeni we-RAID aphezulu, amasistimu asekelwe kwi-hardware avame ukuphinda afinyelele ama-software abo asekelwe kwisofthiwe. Lokhu kusebenza okuthuthukisiwe akukhawulelwanga ekubhaleni nasekufundeni idatha nje kuphela kodwa futhi kubonisa lapho idatha ehlanganisiwe ye-RAID idinga ukuvuselelwa ngenxa yokuhluleka kokushayela. Izinhlelo ze-RAID ezisuselwe ku-Hardware zivame ukwenza inqubo yokwakha kabusha ngokushesha futhi amasistimu asekelwe kwisofthiwe.
- Ngaphezulu: Ukuvalwa kwe-RAID okusekelwe ngaphandle kwe-hardware akumele kuveze umthelela kumprosesa noma ngaphezulu kwe-RAM kwikhompyutha yokusingatha.
- I-Bootable: Ngokujwayelekile, izinhlelo ze-RAID ezisekelwe kwi-hardware zingasetshenziswa njengoba isistimu yakho yebhobhothi inikezela uxhumano kwikhompyutha yakho isebenzisa uhlobo lwe-port ukuthi uhlelo lokusebenza lusekela ukuthutha kusuka. Ama-USB 3 ne-Thunderbolt amabhukwana kufanele asebenze ngokujwayelekile kodwa hlola uhlelo lokusebenza nomkhiqizi wekhompyutha ukuqinisekisa.
Iziphakamiso ze-RAID
- I-RAID esekelwe kwi-software ithola izithupha lapho amandla okushayela egcina izindleko futhi ukusetshenziswa kwakho kwe-RAID kuzobekwa kuphela ku- RAID 0 (emigqabeni), i-Raid 1 (ikhonjisiwe), noma i-RAID 10 (isethi esenzelwe ukushayela) . Lolu hlobo lwe-RAID uhlelo luyisinqumo esihle kubasebenzisi basekhaya abazosebenzisa uhlelo lwe-RAID ngesistimu eyodwa yekhompuyutha.
- I-RAID esekelwe engxenyeni yekhwalithi iyona yokukhetha kokubili ama-setup we-RAID, afana asetshenziswa ku-RAID 3 noma i-RAID 5 efaka ama-bits obuhle ayenziwa futhi aqhathaniswa nesikhathi sangempela njengoba idatha ithunyelwa futhi kusukela ku-RAID. I-RAID esekelwe ngekhwalithi iyisinqumo esihle sezinhlelo eziyisisekelo eziyisisekelo ze-RAID 0 ne-RAID 1 uma ufuna i-RAID enclosure ikwazi ukuzimela ngaphandle kwekhompiyutha ephethe, ikunika ikhono lokuhambisa uhlelo phakathi kwamakhompyutha amaningi.
