Umehluko phakathi kwe-SAS ne-SATA

SASkanye ne-SATA yizicaciso ezimbili ze-interface hard drive, zombili zisebenzisa ubuchwepheshe be-serial, kodwa kukhona umehluko omkhulu ngokuhambisana, isivinini, intengo, njalonjalo.

I-SAS, i-Serial Attached SCSI, noma i-Serial Attached SCSI, isizukulwane esisha sobuchwepheshe be-SCSI esisebenzisa ubuchwepheshe be-serial ukuze kutholwe izivinini zokudlulisa eziphezulu kanye nokuthuthukisa isikhala sangaphakathi ngokunciphisa imigqa yesixhumanisi, njll.Lesi sixhumanisi singathuthukisa ukusebenza, ukutholakala kanye nokulinganisa kwezinhlelo zokugcina futhi sinikeze ukuhambisana namadrayivu aqinile e-SATA.

Ukuhambisana okuhlukile:

1. Kusendlalelo somzimba, i-interface ye-SAS kanye ne-SATA interface iyahambisana ngokugcwele, i-SATA hard disk ingasetshenziswa ngokuqondile endaweni ye-SAS, ngokwezinga le-interface, i-SATA ingaphansi kwe-SAS, ngakho isilawuli se-SAS singakwazi ukulawula ngokuqondile i-SATA hard disk, kodwa i-SAS ayikwazi ukusetshenziswa ngokuqondile endaweni ye-SATA, ngoba isilawuli se-SATA asinakho ukulawula i-SAS hard disk control;

2. Kusendlalelo sephrothokholi, i-SAS iqukethe izinhlobo ezintathu zezivumelwano, ezisetshenziselwa ukudluliswa kwedatha ngokuya ngamadivayisi ahlukene axhunyiwe.I-Serial SCSI Protocol (SSP) isetshenziselwa ukudlulisa imiyalo ye-SCSI;i-SCSI Management Protocol (SMP) isetshenziselwa ukunakekela nokuphatha amadivaysi axhunyiwe;kanye ne-SATA Channel Protocol (STP) isetshenziselwa ukudlulisa idatha phakathi kwe-SAS ne-SATA.Ngakho-ke, ngokubambisana kwalezi zivumelwano ezintathu, i-SAS ingahlanganiswa ngaphandle komthungo ne-SATA kanye namanye amadivaysi e-SCSI.

Isivinini esihlukile:

1. Ijubane le-SAS ngu-12Gbps/S;

2. Ijubane le-SATA ngu-6Gbps/S.

Intengo ehlukile:

Intengo ye-SAS ibiza kakhulu kune-SATA.
