Amadivayisi Esitoreji, Ama-Disk Arrays kanye Nezinhlelo Zokugcina, SAN, NAS

A STORAGE DEVICE or also known as STORAGE MEDIUM is any computing hardware that is used for storing, porting and extracting amafayela wedatha nezinto. Amadivayisi esitoreji angabamba futhi agcine ulwazi okwesikhashana futhi unomphela. Zingaba ngaphakathi noma ngaphandle kukhompuyutha, kuseva noma kunoma iyiphi idivayisi yekhompyutha efanayo.

​

Ukugxila kwethu ku DISK ARRAY okuyinto yehadiwe equkethe iqembu elikhulu lama-hard disk drive (HDD). Ama-disk arraray angase aqukathe amathreyi e-disk drive amaningana futhi abe nezakhiwo ezithuthukisa isivinini kanye nokwandisa ukuvikeleka kwedatha. Isilawuli sesitoreji sisebenzisa isistimu, ehlanganisa umsebenzi ngaphakathi kweyunithi. Ama-disk array awumgogodla wezindawo zesimanje zokugcina zokuxhumana. I-disk array ithi a DISK STORAGE SYSTEM equkethe amadrayivu ediski amaningi futhi ihlukanise11imemori ye-cacc 5 ethuthukisiwe ne-5 enclosure 8 idiski ethuthukisiwe. 3194-bb3b-136bad5cf58d_RAID kanye nokwenza ngokoqobo. I-RAID imele i-Redundant Array of Inexpensive (noma Independent) Disks futhi isebenzisa amadrayivu amabili noma ngaphezulu ukuze kuthuthukiswe ukusebenza nokubekezelela amaphutha. I-RAID inika amandla ukugcinwa kwedatha ezindaweni eziningi ukuze kuvikelwe idatha ekonakaleni futhi inikeze abasebenzisi ngokushesha.

Ukuze ukhethe Idivayisi efanelekile Yesitoreji Sebanga Lemboni yephrojekthi yakho, sicela uye esitolo sethu samakhompyutha sezimboni NGOKUCHOFOZA LAPHA.

Dawuniloda incwajana yethuKALA UHLELO LOKUBAMBISANA

​

Izingxenye zohlelo olujwayelekile lwediski zifaka:

 

Izilawuli ze-Disk array

 

Izinkumbulo zenqolobane

 

Izivalo zediski

 

Izimpahla zamandla

​

Ngokuvamile ama-disk array ahlinzeka ngokutholakala okukhuphukile, ukuqina kanye nokugcinwa ngokusetshenziswa kwezingxenye ezengeziwe, ezingasasebenzi njengezilawuli, izinsiza zamandla, amafeni, njll., ngezinga lokuthi wonke amaphuzu awodwa okwehluleka akhishwe ekwakhiweni. Lezi zingxenye isikhathi esiningi ziyashintshashintsha.

​

Ngokuvamile, ama-disk array ahlukaniswe ngezigaba:

​

I-NETWORK ATTACHED STORAGE (NAS) ARRAYS : I-NAS iyidivayisi yokugcina ifayela ezinikele ehlinzeka abasebenzisi benethiwekhi yendawo (LAN) ngesitoreji sediski esimaphakathi, esihlanganisiwe ngoxhumano olujwayelekile lwe-Ethernet. Idivayisi ngayinye ye-NAS ixhunywe ku-LAN njengedivayisi yenethiwekhi ezimele futhi yabelwe ikheli le-IP. Inzuzo yayo eyinhloko ukuthi isitoreji senethiwekhi asikhawulelwe kumthamo wokugcina wedivayisi yekhompyutha noma inombolo yamadiski kuseva yendawo. Imikhiqizo ye-NAS ngokuvamile ingabamba amadiski anele ukusekela i-RAID, futhi izinto zikagesi eziningi ze-NAS zinganamathiselwa kunethiwekhi ukuze kunwetshwe isitoreji.

​

INETWORK YENDAWO YOKUGCINA (SAN) ARRAYS : Aqukethe uhlu olulodwa lwediski olulodwa noma ngaphezulu olusebenza njengendawo yokugcina idatha ehanjiswa ngaphakathi nangaphandle kwe-SAN. Amalungu afanayo esitoreji axhumeka kungqimba lwendwangu ngamakhebuli agijima esuka kumadivayisi akusendlalelo sendwangu ukuya kuma-GBIC kuzimbobo ohlwini. Kukhona ikakhulukazi izinhlobo ezimbili zenethiwekhi yendawo yokugcina, okuyimodular ama-SAN array kanye ne-monolithic SAN arrays. Zombili zisebenzisa imemori yekhompyutha eyakhelwe ngaphakathi ukusheshisa kanye nokufinyelela kwenqolobane kumadrayivu ediski ahamba kancane. Lezi zinhlobo ezimbili zisebenzisa inqolobane yememori ngokuhlukile. Amalungu afanayo e-Monolithic ngokuvamile anenkumbulo yenqolobane eyengeziwe uma kuqhathaniswa namalungu afanayo e-modular.

​

1.) MODULAR SAN ARRAYS : Lezi zinokuxhunywa kwembobo okumbalwa, zigcina idatha encane yamaseva futhi ixhumeka kumaseva amancane ambalwa. Benza ukuthi umsebenzisi ofana nezinkampani ezincane akwazi ukuqala kancane ngamadrayivu ediski ambalwa futhi andise inombolo njengoba izidingo zokulondoloza zikhula. Anamashalofu okubamba amadrayivu ediski. Uma ixhunywe kumaseva ambalwa kuphela, ama-modular SAN array angashesha kakhulu futhi anikeze izinkampani ukuguquguquka. Ama-Modular array e-SAN angena kumarack ajwayelekile angu-19”. Ngokuvamile zisebenzisa izilawuli ezimbili ezinememori yenqolobane ehlukene endaweni ngayinye futhi zifanekisela inqolobane phakathi kwezilawuli ukuvimbela ukulahleka kwedatha.

​

2.) MONOLITHIC SAN ARRAYS : Lawa amaqoqo amakhulu amadrayivu ediski ezikhungweni zedatha. Angagcina idatha eyengeziwe kakhulu uma kuqhathaniswa nezinhlaka ezifanayo ze-SAN futhi ngokuvamile axhume kuma-mainframes. Amalungu afanayo e-Monolithic SAN anezilawuli eziningi ezingabelana ngokufinyelela okuqondile kunqolobane yememori yomhlaba wonke esheshayo. Amalungu afanayo e-Monolithic ngokuvamile anezimbobo ezibonakalayo ezengeziwe ukuze axhumeke kumanethiwekhi wendawo yokugcina. Ngakho amaseva engeziwe angasebenzisa amalungu afanayo. Ngokujwayelekile ama-monolithic array abaluleke kakhulu futhi anokwesekwa okuphakeme okwakhelwe ngaphakathi nokuthembeka.

​

UKUSETSHENZISWA KWESITOREJI ARRAYS : Kumodeli yesevisi yesitoreji esisetshenziswayo, umhlinzeki unikeza umthamo wesitoreji kubantu ngabanye noma izinhlangano ngesisekelo sokukhokha ngakunye. Le modeli yesevisi ibizwa nangokuthi isitoreji lapho kudingeka khona. Lokhu kusiza ukusetshenziswa kahle kwezinsiza futhi kunciphisa izindleko. Lokhu kungabiza kakhulu ezinkampanini ngokususa isidingo sokuthenga, ukuphatha kanye nokugcina ingqalasizinda ehlangabezana nezidingo eziphezulu ezingaba ngaphezu kwemikhawulo edingekayo yamandla.

​

I-STORAGE VIRTUALIZATION : Lokhu kusebenzisa i-virtualization ukunika amandla ukusebenza okungcono nezici ezithuthuke kakhulu ezinhlelweni zokugcina idatha yekhompyutha. I-Virtualization yesitoreji ukuhlanganisa okusobala kwedatha kusuka kuhlobo olufanayo noma ezinhlotsheni ezahlukahlukene zamadivayisi wesitoreji kulokho okubonakala kuyidivayisi eyodwa ephethwe kusuka kukhonsoli emaphakathi. Isiza abaphathi besitoreji ukuthi benze ikhophi yasenqolobaneni, bagcine kungobo yomlando kanye nokuthola kalula kalula nangokushesha ngokunqoba inkimbinkimbi yenethiwekhi yendawo yokugcina (i-SAN). Lokhu kungafezwa ngokusebenzisa i-virtualization ngezinhlelo zesofthiwe noma ngokusebenzisa i-hardware ne-software hybrid appliances.
