Izicelo:
Izintambo ze-MINI SAS zisetshenziswa kakhulu kumakhompyutha, ekudluliseni idatha kanye nakumadivayisi eseva.
ISIXHUMANISI:
Isiphetho sesixhumi esibonakalayo se-MINI SAS Slimline SFF-8654 8i 4.0:
Lolu uhlobo lwesixhumi esibonakalayo esincane futhi esincane, esivame ukusetshenziselwa ukuxhuma imishini yeseva yangaphakathi ukuze kongiwe isikhala. Phakathi kwazo, i-"8i" isho ukuthi ineziteshi zokufaka/zokukhipha ezingu-8, ezivumela ukudluliselwa kwesignali yeziteshi eziningi futhi zinikeza isisekelo sokudluliselwa kwedatha ngesivinini esikhulu. Isixhumi esibonakalayo se-SFF-8654 sihambisana nezinga le-SAS 4.0 futhi sinomkhawulokudonsa wokudlulisa kanye nesivinini esiphezulu, okungahlangabezana nesidingo seseva sokudluliselwa okusheshayo kwenani elikhulu ledatha.
Isiphetho sesixhumi esibonakalayo se-SAS HD 2X 8643:
I-SAS HD (High Density) iyi-interface ye-SAS enobukhulu obuphezulu. I-"2X" isho ukuthi ine-interface ezimbili ezinjalo. I-8643 iyindinganiso yemodeli ethile yalesi sixhumi. Lesi sixhumi sivame ukusetshenziselwa ukuxhuma amadivayisi afana nama-hard disk nama-array esitoreji, futhi sinokuthembeka okuphezulu nokuzinza, futhi singasekela ukudluliselwa kwedatha okusheshayo kanye nesitoreji.

Yiziphi izici zezintambo ze-SAS kanye nezintambo ze-SAS
Ikhebula le-SAS liyinkambu yokugcina yemidiya yediski iyidivayisi ebaluleke kakhulu, yonke idatha nolwazi kufanele lugcinwe kumidiya yediski. Isivinini sokufunda idatha sinqunywa yi-interface yokuxhuma yemidiya yediski. Esikhathini esidlule, besilokhu sigcina idatha yethu ngokusebenzisa izixhumi ze-SCSI noma ze-SATA kanye nama-hard drive. Kungenxa yentuthuko esheshayo yobuchwepheshe be-SATA kanye nezinzuzo ezahlukahlukene ukuthi abantu abaningi bazocabanga ukuthi ikhona yini indlela yokuhlanganisa i-SATA ne-SCSI, ukuze izinzuzo zazo zombili zidlalwe ngesikhathi esisodwa. Kulesi simo, kuvele i-SAS. Amadivayisi okugcina axhunyiwe angahlukaniswa cishe ngezigaba ezintathu ezinkulu, okungukuthi, i-middle-end ephezulu kanye ne-near-end (Near-Line). Amadivayisi okugcina aphezulu ikakhulukazi ayi-Fibre channel. Ngenxa yesivinini sokudlulisa esisheshayo se-Fibre channel, amadivayisi amaningi okugcina i-optical fiber asetshenziswa ekugcinweni kwedatha yokhiye wezinga lomsebenzi omkhulu. Idivayisi yokugcina ephakathi nendawo ikakhulukazi amadivayisi e-SCSI, futhi inomlando omude, isetshenziswa ekugcinweni kwedatha ebalulekile yezinga lokuhweba. Ifushaniswe ngokuthi (SATA), isetshenziswa ekugcinweni okukhulu kwedatha engabalulekile futhi ihloselwe ukufaka esikhundleni sekhophi yokusekelayo yedatha yangaphambilini kusetshenziswa itheyiphu. Inzuzo engcono kakhulu yamadivayisi okugcina i-Fibre Channel ukudluliswa okusheshayo, kodwa inentengo ephezulu futhi kunzima ukuyinakekela; Amadivayisi e-SCSI anokufinyelela okusheshayo kanye nentengo ephakathi, kodwa anwetshiwe kancane, ikhadi ngalinye lesikhombimsebenzisi se-SCSI lixhuma amadivayisi afinyelela ku-15 (isiteshi esisodwa) noma angu-30 (amashaneli amabili). I-SATA ubuchwepheshe obuthuthuka ngokushesha eminyakeni yamuva. Inzuzo yayo enkulu ukuthi ishibhile, futhi ijubane alinciphi kakhulu kunesikhombimsebenzisi se-SCSI. Ngokuthuthuka kobuchwepheshe, isivinini sokufunda idatha se-SATA siyasondela futhi sidlula isikhombimsebenzisi se-SCSI. Ngaphezu kwalokho, njengoba i-hard disk ye-SATA ishibhile futhi ibiza kakhulu, ingasetshenziswa kancane kancane ekulondolozeni idatha. Ngakho-ke isitoreji sebhizinisi sendabuko ngoba uma sicabangela ukusebenza nokuzinza, nge-SCSI hard disk kanye ne-fiber optic channel njengesikhulumi esiyinhloko sokugcina, i-SATA isetshenziswa kakhulu kwidatha engabalulekile noma kwikhompyutha yomuntu siqu yedeskithophu, kodwa ngokukhula kobuchwepheshe be-SATA kanye nemishini ye-SATA evuthiwe, le modi iyashintshwa, abantu abaningi baqala ukunaka i-SATA ngale ndlela yokuxhumeka kwedatha yochungechunge.
