Kubalulekile ukuhlukanisa phakathi kwemiqondo ye "port" kanye "nesixhumi".Izimbobo zamadivayisi wehadiwe zibizwa nangokuthi i-interfaces, amasignali azo kagesi achazwa ngokucaciswa kwesixhumi esibonakalayo, futhi inombolo incike ekwakhiweni kwe-Controller IC (okuhlanganisa ne-RoC).Kodwa isixhumi esibonakalayo noma imbobo, kufanele incike kusimo esibonakalayo - ikakhulukazi izikhonkwane nezengezo, zingadlala indima yokuxhuma, bese zenza umzila wedatha.Ngakho-ke izixhumi ze-interface, ezihlala zisetshenziswa ngababili: uhlangothi olulodwa ku-hard drive, i-HBA, ikhadi le-RAID, noma i-backplane "iqhuma" kanye nolunye uhlangothi ohlangothini olulodwa lwekhebula.Ngokuqondene nesixhumi sesamukeli (isixhumi sesitsha) nesixhumi sepulaki (isixhumi sepulaki), kuncike ekucacisweni kwesixhumi esithile.
Izintambo ze-SATA nezixhumi zilula.Imbobo eyodwa ihambisana nesixhumi esibonakalayo esisodwa, futhi ikhebula linoxhumano olulodwa kuphela.I-SAS, ngakolunye uhlangothi, isekela izixhumanisi ezine ezibanzi kusukela ekuqaleni futhi ivumela izimbobo zezixhumanisi ezingafika kwezine eziwumngcingo ukuthi zihlanganiswe zibe imbobo eyodwa ebanzi, futhi ukucaciswa kwesixhumi okuhambisanayo kuyenziwa.Ngenxa yalokho, kunezinhlobo okungenani ezimbili zezixhumi ze-SAS interface.Ngaphezu kwalokho, kunenqwaba yezintambo ze-SAS ezingahlanganiswa.Izinhlobonhlobo zezintambo ze-SAS zikhulu nakakhulu uma ucabangela izinguquko ekubunjweni kwezixhumi ze-interface abakhiqizi bamakhompyutha abazenzele izintambo.
I-SAS iqala ichaza isixhumi esibonakalayo se-hard drive, futhi ukucaciswa kwayo yi-SFF-8482.I-interface ye-SAS hard drive interface iyafana nesixhumi esibonakalayo se-SATA hard drive, ngaphandle komklamo wayo wokukhiya ukhiye oqinile ukuvimbela i-SAS ukuthi ingaxhumeki ezinhlelweni zokushayela ze-SATA, futhi izintambo zedatha ye-SATA azikwazi ukuxhunywa ngokuqondile kuma-hard drive e-SAS.Kodwa izintambo ze-SAS ziyahambisana nama-hard drive e-SATA.
Isixhumi SangaphakathiI-Mini SAS 4i (SFF-8087)
