Kufambisa kuverenga kwezvitsauko zvinotevera mubhuku rino, heano mamwe akakosha edhisiki array kuchengetedza mazwi. Kuchengetedza kuwirirana kwezvitsauko, tsananguro dzakadzama dzehunyanzvi hadzizopihwe.
SCSI:
Pfupi kune Diki Computer System Interface, yakatanga kugadzirwa muna 1979 seye interface tekinoroji yemakomputa-makomputa asi ikozvino yakatakurwa zvizere kumaPC akajairwa nekufambira mberi kwekombuta.
ATA (AT Attachment):
Iyo inozivikanwawo seIDE, iyi interface yakagadzirirwa kubatanidza bhazi reAT komputa rakagadzirwa muna 1984 zvakananga kune akasanganiswa madhiraivha uye ma controller. Iyo "AT" muATA inouya kubva pakombuta yeAT, yaive yekutanga kushandisa ISA bhazi.
Seri ATA (SATA):
Inoshandisa serial data kuendesa, kuendesa chete chidimbu chimwe che data pawachi kutenderera. Nepo ma ATA hard drives agara ashandisa parallel transfer modes, ayo anogona kutapukirwa nekukanganiswa kwechiratidzo uye kukanganisa kugadzikana kwehurongwa panguva yekumhanyisa data data, SATA inogadzirisa nyaya iyi nekushandisa serial yekuchinjisa modhi ine chete 4-waya tambo.
NAS (Network Attached Storage):
Iyo inobatanidza midziyo yekuchengetedza kune boka remakomputa uchishandisa yakajairwa network topology senge Ethernet. NAS inhengo-chikamu chekuchengetedza nzira yakanangana nekugadzirisa kudiwa kuri kukura kwekuwedzera kwekuchengetedza huwandu mumapoka ebasa uye masangano-padanho redhipatimendi.
DAS (Yakananga Yakanamirwa Kuchengeta):
Zvinoreva kubatanidza midziyo yekuchengetera yakananga pakombuta kuburikidza neSCSI kana Fiber Channel nzvimbo. Zvigadzirwa zveDAS zvinosanganisira zvigadziriso zvekuchengetedza uye zvakasanganiswa maseva akareruka anogona kuita mabasa ese ane chekuita nekuwana faira uye manejimendi.
SAN (Storage Area Network):
Inobatana neboka remakomputa kuburikidza neFiber Channel. SAN inopa akawanda-anotambira yekubatanidza asi haishandise yakajairwa network topologies. SAN inotarisa pakugadzirisa nyaya dzine chekuita nekuchengetedza munzvimbo dzemabhizinesi uye inonyanya kushandiswa munzvimbo dzekuchengetedza.
Array:
Inoreva dhisiki system inoumbwa nemadhisiki akawanda anoshanda mukufanana. A RAID controller anosanganisa akawanda dhisiki kuita array achishandisa yayo SCSI chiteshi. Mumashoko akapfava, array idhisiki system ine madhisiki akawanda anoshanda pamwechete achienderana. Izvo zvakakosha kuti uzive kuti dhisiki dzakasarudzwa sezvipfuyo zvinopisa hazvigone kuwedzerwa kune array.
Array Spanning:
Zvinosanganisira kubatanidza nzvimbo yekuchengetera maviri, matatu, kana mana dhisiki arrays kugadzira zvine musoro dhiraivha ine inoenderera yekuchengetedza nzvimbo. RAID controllers inogona kutarisa akawanda arrays, asi imwe neimwe array inofanira kuva nenhamba yakafanana yemadhisiki uye yakafanana RAID level. Semuenzaniso, RAID 1, RAID 3, uye RAID 5 inogona kuiswa kuti iite RAID 10, RAID 30, uye RAID 50, zvichiteerana.
Cache Policy:
Iyo inoreva caching zano reRAID controller, inogona kunge iri Cached I/O kana Direct I/O. Cached I/O inoshandisa nzira dzekuverenga nekunyora uye kazhinji inochengeta data panguva yekuverenga. Yakananga I / O, kune rumwe rutivi, inoverenga data nyowani zvakananga kubva kudhisiki kunze kwekunge dhisiki yedata ichidzokororwa kuwanikwa, mune iyo kesi inoshandisa ine mwero kuverenga zano uye caches iyo data. Muzviitiko zvekuverenga zvisina kurongeka, hapana data rakachengetwa.
Kuwedzerwa Kwesimba:
Kana iyo chaiyo yekugona sarudzo yakaiswa kuti iwanikwe mune yeRAID controller yekukurumidza kumisikidza utility, mutongi anogadzika virtual disk nzvimbo, achibvumira mamwe emuviri madhisiki kuti awedzere munzvimbo chaiyo kuburikidza nekuvakazve. Kuvaka patsva kunogona kungoitwa pane imwechete inonzwisisika drive mukati meiyo imwe array, uye kuwedzera kwepamhepo hakugone kushandiswa mune yakatambanudzwa array.
Channel:
Iyo inzira yemagetsi inoshandiswa kuendesa data uye kutonga ruzivo pakati pevaviri dhisiki controller.
Format:
Ndiyo maitiro ekunyora zero pane ese data nzvimbo dzemuviri dhisiki (hard drive). Mafomati ibasa chairo remuviri iro rinosanganisirawo kuenderana kwekutarisa dhisiki yepakati uye kumaka isingaverengeki uye yakaipa zvikamu. Sezvo akawanda madhiraivha akaomarara akatofomatidzwa pafekitori, kufomatidza kunongodiwa chete kana dhisiki zvikanganiso zvikaitika.
Hot Spare:
Kana dhisiki razvino rinoshanda rikatadza, isina basa, powered-on spare disk pakarepo inotsiva dhisiki rakakundikana. Iyi nzira inozivikanwa sehot sparing. Madhisiki anopisa haachengete chero data remushandisi, uye anosvika sere dhisiki anogona kusarudzwa seanopisa spares. Iyo inopisa spare dhisiki inogona kutsaurirwa kune imwe chete yakadzoserwa array kana kuve chikamu chehot spare disk pool kune ese array. Kana dhisiki kukundikana kunoitika, iyo firmware yemutongi inotsiva iyo yakakundikana dhisiki nehot spare disk uye inovakazve data kubva kune yakakundikana disk kuenda kune inopisa spare disk. Iyo data inogona kungovakwa patsva kubva kune yakarebesa logic drive (kunze kweRAID 0), uye inopisa spare disk inofanira kunge iine kukwana kwakakwana. Iyo system administrator inogona kutsiva iyo yakakundikana dhisiki uye sarudza yekutsiva dhisiki seyakatsva inopisa spare.
Hot Swap Disk Module:
Hot swap mode inobvumira vatariri vehurongwa kutsiva yakundikana disk drive pasina kuvhara sevha kana kukanganisa network masevhisi. Sezvo masimba ese uye tambo dzekubatanidza dzakabatanidzwa pane sevha yekumashure, kupisa kupisa kunosanganisira kungobvisa dhisiki kubva kune drive cage slot, iri nzira yakatwasuka. Zvadaro, iyo yekutsiva inopisa dhisiki inoiswa mune slot. Kupisa tekinoroji yekuchinja inongoshanda mukumisikidzwa kweRAID 1, 3, 5, 10, 30, uye 50.
I2O (Intelligent Input/Output):
I2O iindasitiri yakajairwa dhizaini yekuisa / kubuda subsystems yakazvimirira yetiweki inoshanda sisitimu uye haidi rutsigiro kubva kune ekunze zvishandiso. I2O inoshandisa zvirongwa zvemutyairi zvinogona kukamurwa kuita Operating System Services Modules (OSMs) uye Hardware Device Modules (HDMs).
Kutanga:
Iyo ndiyo maitiro ekunyora zero pane data nzvimbo yeane musoro dhiraivha uye kugadzira inoenderana parity mabhiti kuunza zvine musoro dhiraivha munzvimbo yakagadzirira. Initialization inodzima yapfuura data uye inogadzira parity, saka zvine musoro dhiraivha inosangana nekutarisa kunoenderana panguva iyi. Mutsara usina kutangwa haushandiswe nekuti hausati wagadzira kuenzanirana uye zvinozokonzera kukanganisa kwekutarisa.
IOP (I/O processor):
Iyo I / O processor ndiyo nzvimbo yekuraira yeRAID controller, ine basa rekuraira kugadzirisa, kuendesa data paPCI neSCSI mabhazi, RAID kugadzirisa, disk drive kuvaka, cache manejimendi, uye kukanganisa kudzoreredza.
Logic Drive:
Iyo inoreva kune chaiyo dhiraivha mune array iyo inogona kutora anopfuura imwechete yemuviri dhisiki. Madhiraivha anonzwisisika anokamura madhisiki muhurongwa kana kuti akatambanudzwa munzvimbo dzinoramba dzichichengeterwa dzakagoverwa pamadhisiki ese ari muhurongwa. A RAID controller anogona kuseta kusvika ku8 zvine musoro madhiraivha emhando dzakasiyana, ine inokwana imwechete inonzwisisika drive inodiwa pane array. Kupinza/kuburitsa mashandiro anogona kuitwa chete kana zvine musoro dhiraivha iri online.
Izwi Rinonzwisisika:
Iyo idhisiki chaiyo inogadzirwa nemadhiraivha anonzwisisika, anozivikanwawo se disk partitions.
Mirroring:
Iyo imhando yekudzokororwa uko data pane imwe dhisiki inoratidzirwa pane imwe dhisiki. RAID 1 uye RAID 10 inoshandisa mirroring.
Parity:
Mukuchengetedza data uye kutapurirana, kuenzana kunosanganisira kuwedzera imwe diki kune byte kutarisa kukanganisa. Inowanzo gadzira data yakawandisa kubva kune mbiri kana kupfuura yepakutanga data, iyo inogona kushandiswa kuvakazve yepakutanga data kubva kune imwe yekutanga data. Nekudaro, data reparity haisi kopi chaiyo yedata rekutanga.
MuRAID, iyi nzira inogona kushandiswa kune ese madhisiki madhiraivha mune array. Parity inogona zvakare kugoverwa kune ese madhisiki muhurongwa mune yakatsaurirwa parity kumisikidzwa. Kana dhisiki ikakundikana, iyo data padhisiki yakakundikana inogona kuvakwa zvakare uchishandisa iyo data kubva kune mamwe madhisiki uye parity data.
