Kungenzeka ukuthi muva nje ngaphezu kweyodwa kini owake wezwa igama elithi DAS. Kuyinto esizwa njalo futhi kaningi, futhi lokho kutholakala kubhulogi abaningi. Ngakho-ke, kuhle ukwazi ukuthi leli gama lisho ukuthini nokuthi lisho ukuthini kuleli cala. Ngenkathi kungahle kube khona abanye abasebenzisi abanomqondo othile, kepha bafuna ukwazi kabanzi.
Okulandelayo sikutshela ukuthi yini i-DAS, lisho ukuthini leli gama. Siphinde sisho ukuthi yiziphi izici eziyinhloko esizithola kokukodwa. Ngakho-ke kuyacaca ukuthi yini esingayilindela kokukodwa. Okungasiza kakhulu iningi lenu.
Yini i-DAS
I-DAS sekuyigama elidumile, elivela ekumiseni amagama asetshenziswayo lapho sihlukanisa izakhiwo ezihlukile zokugcina ezisetshenziselwa ukwenza ikhompyutha. Esimweni esinjalo, I-DAS isichazamazwi se-Direct Attached Storage, okuthi uma silitolikela olimini lwesiSpanishi singalichaza njengesitoreji esixhumene ngqo. Kuyindlela engcono yokuchaza lezi zinhlobo zemikhiqizo.
Sithola amadivayisi amaningi kulesi sigaba. Singafaka ezinye ezifana ama-hard drive, ama-optical disc drives (CD, DVD, BD), izinti ze-USB, ama-solid state disk drives, kanye nezinhlelo ezindala ezingasasetshenziswa namuhla, njenge-floppy drives, isibonelo. Ngakho-ke yisigaba esibanzi impela, esifaka phakathi imikhiqizo eminingi.
Yize into ejwayelekile ukuthi uma sikhuluma nge-DAS, sibhekisa ngaphezu kwakho konke kulokhu okukhethwa kukho, okuyi-HDD ne-SSD. Yize imboni nayo iguqukile futhi leli gama belilokhu likhula noma lisetshenziswa ngendlela ehlukile. Kusukela namuhla siyabona ukuthi zingaki izinkampani ezisebenzisa leli gama ukuchaza indawo ebiyelweyo, enamandla okwakha izindlu eziningana ze-SSD noma ze-HDD. Yinto esiyibona iya ngokwanda emakethe namuhla.
Izici ze-DAS
Lapho nje sesinombono oqondile wokuthi leli gama lisho ukuthini, kunezinto eziningi esingazilindela ku-DAS. Esikhundleni salokho, uchungechunge lwezici le mikhiqizo evame ukuletha ngokujwayelekile, okuyizinto ezisisizayo ukuthi sizikhombe kulesi sigaba semikhiqizo. Kunezinombolo zazo okufanele sizikhumbule, ngoba zibaluleke kakhulu kulokhu. Impela iningi lazo lizwakala lijwayelekile kuwe, ngoba yizo ezichaza kahle yonke into eyi-DAS namuhla, njengoba kuqondwa:
- Bavumela ukufinyelela okusheshayo kulo lonke ulwazi olugciniwe noma olugciniwe
- Bavumela ukuxhumeka ebhokisini noma ngendlela yangaphandle (ngetheku le-USB, noma kusifundi sediski)
- Banokuxhumana okuqondile neseva noma indawo yokusebenza, ngokusebenzisa i-adaptha yebhasi ye-Host (HBA)
- Ayikho i-hardware yenethiwekhi phakathi kwedivayisi nekhompyutha
- Usekela ukwahlukanisa noma ukufometha
- Ayahambisana nokuhlangana kwebhasi.Amakhompyutha we-SATA, eSATA, SAS noma SCSI yiwona avame kakhulu, kodwa futhi namanye afana ne-ATA, PATA noma IEEE 1394, phakathi kwamanye amaningi.
I-DAS inezinzuzo eziningi ezibalulekile. Enye yezinto ezibaluleke kakhulu intengo, ngoba zitholakala kalula, ukuze abasebenzisi abaningi bakwazi ukufinyelela eyodwa, ezinhlokweni zayo ezahlukahlukene. Ngaphezu kwalokho, njengoba kunezinhlobo eziningi, kulula ukuthola eyodwa elingana necala ngalinye, elibalulekile njalo.
Ngaphezu kwalokho, zizinzile futhi zivikela imininingwane esiyigcina kuzo. Intengo yayo iphansi, kepha futhi izindleko zesondlo zabasebenzisi ziphansi impela, hhayi ukusho cishe u-zero, okungangabazeki okubenza babe inketho enhle abangayicabangela kulokhu. Ngakho-ke i-DAS yinto enezinzuzo eziningi.
