Ndezvipi zvinhu zveSAS tambo uye tambo dzeSAS

SAS tambo ndiyo nzvimbo yekuchengetedza yedhisiki midhiya ndiyo inonyanya kukosha mudziyo, data rese uye ruzivo runofanira kuchengetwa padhisiki midhiya. Iyo yekumhanyisa yekuverenga data inotsanangurwa nekubatanidza interface yedhisiki media. Munguva yakapfuura, tagara takachengeta data redu kuburikidza neSCSI kana SATA interfaces uye hard drive. Imhaka yekukurumidza kukura kweSATA tekinoroji uye zvakanakira zvakasiyana izvo vanhu vazhinji vanozofunga kana paine nzira yekubatanidza ese SATA neSCSI, kuitira kuti zvakanakira zvese zviri zviviri zvinogona kuridzwa panguva imwe chete. Muchiitiko ichi, SAS yakabuda. Netiweki midziyo yekuchengetedza inogona kukamurwa kuita zvikamu zvitatu zvikuru, zvinoti, yepamusoro-yepakati-yepakati uye padyo-kumagumo (Near-Line). Yepamusoro-yekupedzisira yekuchengetedza michina inonyanya Fiber chiteshi. Nekuda kwekukurumidza kufambisa kumhanya kweFiber chiteshi, akawanda epamusoro-ekupedzisira ekuchengetedza optical fiber zvishandiso zvinoshandiswa kune yakakura-chaiyo-chaiyo-nguva yekuchengetedza yebasa-level kiyi data. Iyo yepakati-renji yekuchengetera mudziyo inonyanya kushandiswa neSCSI zvishandiso, uye zvakare ine nhoroondo refu, ichishandiswa mukuchengetwa kwehuwandu hwekutengesa-level yakakosha data. Yakapfupikiswa se (SATA), inoshandiswa pakuchengetwa kwehuwandu hwe data isiri-yakakosha uye inoitirwa kutsiva yapfuura data backup uchishandisa tepi. Iyo yakanakisa mukana weFiber Channel yekuchengetera zvishandiso inokurumidza kutapurirana, asi ine mutengo wakakwira uye yakaoma kuchengetedza; SCSI zvishandiso zvine kukurumidza kuwana uye yepakati mutengo, asi ishoma kuwedzeredzwa, yega yega SCSI interface kadhi inobatanidza kusvika gumi neshanu (imwe chiteshi) kana makumi matatu (mbiri-channel) zvishandiso. SATA tekinoroji inokurumidza kukura mumakore achangopfuura. Kubatsira kwayo kukuru ndeyekuti yakachipa, uye kumhanya hakuna kunonoka kupfuura iyo SCSI interface. Nekuvandudzwa kwetekinoroji, kumhanya kweSATA yekuverenga data kuri kusvika nekupfuura iyo SCSI interface. Mukuwedzera, sezvo SATA's hard disk iri kudhura uye ichidhura, inogona kushandiswa zvishoma nezvishoma kuchengetedza data. Saka chinyakare bhizinesi rekuchengetedza nekuti tichifunga nezvekuita uye kugadzikana, neSCSI hard disk uye faibha optic chiteshi seyo huru yekuchengetera chikuva, SATA inonyanya kushandiswa kune isiri-yakakosha data kana desktop komputa yega, asi nekukwira kweSATA tekinoroji uye SATA midziyo yakakura, iyi modhi iri kuchinjwa, vanhu vazhinji vakatanga kuterera SATA iyi serial data yekuchengetedza nzira yekubatanidza.
