I-Mini SAS HD SFF-8643 ukuya ku-4 SATA 7P Yekhebula Yokuxhuma Yeseva Yesilisa

Yiziphi izici zezintambo ze-SAS nezintambo ze-SAS

Ikhebula le-SAS liyindawo yokugcina imidiya yediski iyithuluzi elibaluleke kakhulu, yonke idatha nolwazi kufanele kugcinwe kumidiya yediski. Isivinini sokufunda sedatha sinqunywa isikhombimsebenzisi sokuxhuma semidiya yediski. Esikhathini esidlule, besilokhu sigcina idatha yethu ngokusebenzisa i-SCSI noma i-SATA interface nama-hard drive. Kungenxa yokuthuthukiswa okusheshayo kobuchwepheshe be-SATA kanye nezinzuzo ezihlukahlukene ukuthi abantu abaningi bazocabangela ukuthi kukhona yini indlela yokuhlanganisa kokubili i-SATA ne-SCSI, ukuze izinzuzo zombili zidlalwe ngesikhathi esifanayo. Kulokhu, i-SAS iye yavela. Amadivayisi okulondoloza axhumene nenethiwekhi angahlukaniswa cishe abe izigaba ezintathu ezinkulu, okungukuthi, ekupheleni okuphakathi nendawo kanye nasekupheleni (Near-Line). Amadivayisi esitoreji asezingeni eliphezulu ikakhulukazi isiteshi se-Fiber. Ngenxa yesivinini sokudlulisa esisheshayo sesiteshi se-Fiber, amathuluzi amaningi we-fiber optical fiber yokugcina ephezulu asetshenziswa ekugcinweni kwesikhathi sangempela komthamo omkhulu wedatha yokhiye wezinga lomsebenzi. Idivayisi yokugcina yebanga eliphakathi kakhulu ingamadivayisi e-SCSI, futhi inomlando omude, isetshenziswa ekugcinweni kwenqwaba yedatha ebalulekile yezinga lezentengiso. Ifushanisiwe njenge-(SATA), isetshenziswa ekugcinweni kwenqwaba yedatha engabalulekile futhi ihloselwe ukufaka isipele sedatha yangaphambilini kusetshenziswa itheyiphu. Inzuzo engcono kakhulu yamadivayisi wesitoreji se-Fiber Channel ukudluliswa okusheshayo, kodwa inenani eliphezulu futhi kunzima ukuyigcina; Amadivayisi e-SCSI anokufinyelela okusheshayo uma kuqhathaniswa nenani eliphakathi nendawo, kodwa inwetshiwe kancane, ikhadi ngalinye le-SCSI lixhuma kufika ku-15 (isiteshi esisodwa) noma amadivaysi angu-30 (ama-dual-channel). I-SATA ubuchwepheshe obuthuthuka ngokushesha eminyakeni yamuva. Inzuzo yayo enkulu ukuthi ishibhile, futhi ijubane alinensa kakhulu kune-SCSI interface. Ngokuthuthuka kobuchwepheshe, isivinini sokufunda idatha se-SATA siyasondela futhi sidlula isixhumi esibonakalayo se-SCSI. Ukwengeza, njengoba i-hard disk ye-SATA iya ishibhile futhi ibiza kakhulu, ingasetshenziswa kancane kancane ukulondoloza idatha. Ngakho-ke isitoreji sebhizinisi lendabuko ngoba ucabangela ukusebenza nokuzinza, ne-SCSI hard disk kanye nesiteshi se-fiber optic njengesikhulumi esikhulu sokugcina, i-SATA isetshenziselwa kakhulu idatha engabalulekile noma ikhompyutha yomuntu siqu yedeskithophu, kodwa ngokukhuphuka kobuchwepheshe be-SATA kanye nemishini ye-SATA. abavuthiwe, le modi iyashintshwa, abantu abaningi baqala ukunaka i-SATA le ndlela yokuxhuma isitoreji sedatha ye-serial.
