SAS-amasondo: isiqu, incazelo, izici lobuchwepheshe zedivayisi

Ukuthenga afanayo noma iseva nokugcina imininingwane, sima phambi ngikhethe onjani hard drive ezifakiwe. Ethandwa kakhulu kukhona lezi zinhlobo ezilandelayo hard drive: SAS, Sata futhi NL-SAS. Lezi zinhlobo ezintathu basonta kwisitoreji semidiya esheshayo, baqhubeka iningi idatha emhlabeni. Isihloko yethu igxile Uhlobo lokuqala. Sibheka iziphi SAS-ngemoto, kanye nemingcele zabo, futhi yini umehluko phakathi izinhlobo eziyisisekelo lezi amadivaysi.

izici lobuchwepheshe

SAS-amasondo esikhundleni SCSI-hlobo. Laba baye baba indinganiso entsha ulwazi isitoreji ibhizinisi-class. Of izinhlobo ezintathu SAS-ngemoto ezibhekwa enokwethenjelwa kakhulu, bayakwazi ukulondoloza ukusebenza ngendlela izimo zokusebenza ezinzima kakhulu. SAS ngemoto ukwenza uhlobo ngemoto NL ngcono kakhulu noma Sata. Inkomba imele nokwethenjelwa ipharamitha ezifana iphutha bit. It kunquma ukuthi kungenzeka iphutha elilodwa kancane kungenzeka idatha kwabezindaba. Izinga Iphutha uhlobo SAS HDD uqobo iyunithi 10 ¹⁶ izingcezu. Okungukuthi, kusho ukuthi ematfuba nephutha kungenzeka kwelinye kweziyishumi quadrillion izingcezu. Ngokwesibonelo, singaqhathanisa izinga nge value iphutha Sata hard disk uhlobo, lapho ke ingenye 10 ¹⁵ (noma omunye quadrillion). Njengoba singabona, ukuvikelwa Sata-HDD Nokho ubuye ngempela okusezingeni eliphezulu, lapho kukhona umbuzo mayelana nokuvikelwa idatha egcinwe, umehluko owodwa ukuze kubaluleke kakhulu.

SAS-amasondo ezivezwa ezindinganisweni kuqine kakhulu ekuthuthukiseni nezinye izinhlobo oshayelayo. Ngakho, lobu buchwepheshe libhekene Ngalesi sikhathi phakathi ukwehluleka, amahora ayizigidi ezingu-1.6 Sata-Technology - 1,2 million. Ngaphezu kwalezi nemingcele, abalawuli kanye ngemoto yalolu hlobo kufanele imiyalo abaningi enzelwe ukuze kuhlonzwe. Lezi zici ukwenza lobu buchwepheshe kahle ezingaphezu kuka Sata. Lokhu kubonakala ikakhulukazi ezimeni force majeure.

NL-ngemoto

Lokhu ubuchwepheshe "umdlali omusha" emakethe. NL-amasondo hybrid: Sata-HDD nge SAS uhlobo isixhumi. Okungukuthi, ijubane, nenhloko ukugcwaliswa othathwe Sata-ubuchwepheshe, esibonakalayo kuyahambisana ngokugcwele SAS. NL-ubuchwepheshe kubhekwe amadiski eliphansi in ukusebenza (ngenxa iphansana ijubane ukujikeleza). Nokho, kuyinto kuyavumelana ngokuphelele nalo nabo oda of the amaqembu, kanye multi-Ukusakaza nokusekelwa Sebawoti amaningi.

Tagirovannaya oda imiyalo ukuthumela multi-Ukusakaza

Kanyekanye Ukudidiyela amaqoqo multiple of isitoreji dokhumenti, futhi isitoreji isilawuli ngaphambilini Imininingwane idluliselwa kakhulu kahle. SAS-ubuchwepheshe sihlinzekela eziningana iziteshi esigcwele Duplex of idatha, okunikeza ukufinyelela okusheshayo ulwazi olugcinwe. Omunye-hard drive SAS-uhlobo zingalawulwa kusuka PC eziningana ngaphandle kokusebenzisa ukushintshwa.

isiphetho

Eqinisweni, i-SAS futhi Sata ubuchwepheshe zenzelwe ngezinhloso ezehlukene: lokuqala wokubekezelela iphutha kanye nokusebenza, kanti eyesibili - ukuqinisekisa iziqukathi. Ngakho abanayo ukuze bancintisane.
