SAS (Serial Attached SCSI), kev twb kev txuas me me computer system interface. SAS yog lub caij tshiab ntawm SCSI cov cuab yeej siv. Nws yog tib yam li qhov nrov Serial ATA (SATA) hard disk. Nws siv kev siv tshuab ua kom muaj kev sib kis ceev dua thiab pab kho qhov chaw sab nraud los ntawm txoj kev txuas cov kab txuas. SAS yog tus tshiab interface tsim tom qab sib txuam nrog SCSI. Qhov interface no yog tsim los txhim kho qhov kev ua tau zoo, qhov muaj, thiab kev sojntsuam ntawm qhov system thiab muab kev sib haum nrog Serial ATA (SATA) nyuaj drives.
SAS interface tshuab rov qab tshaj SATA. Tom qab lub vaj huam sib luag ntawm SAS system tau txuas nrog lub dual-port, kev kawm siab SAS los sis muaj peev xwm, qis dua SATA tsav. Vim tias qhov chaw nres tsheb ntawm SAS tsav zoo li qhov chaw nres nkoj zoo ib yam ntawm SATA tsav, SAS drives thiab SATA drives yuav muaj nyob rau hauv ib qho chaw ceev cia. Txawm li cas los xij, nws yuav tsum raug sau tseg tias SATA system tsis sib haum nrog SAS, yog li SAS tsav tsis tuaj yeem raug txuas nrog SATA pob txha. Vim cov kev sib tw ntawm SAS, IT neeg ua haujlwm siv tau cov disks uas muaj ntau yam kev sib tshuam los ua kom tau raws li lub peev xwm lossis kev ua haujlwm ntawm ntau cov ntawv. Yog li no, thaum cog cov tshuab cia, lawv muaj ntau qhov yooj yim kom muaj txiaj ntsig zoo ntawm kev siv nyiaj cia.
SAS technology kuj muaj qhov kom zoo dua ntawm simplifying sab hauv kev tsim. Cia cov khoom lag luam yog tam sim no nqis peev ntau nqi los txhawb kev sib txawv xws li Fiber Channel arrays, SATA arrays, etc., thiab SAS connectivity technology yuav txo cov nqi tsim los ntawm kev sib koom ua ke.
