Mini SAS HD SFF-8644 Poj Niam nrog Shield rau 4X SATA 7P Server Hard Disk High-Speed ​​Conversion Cable

Dab tsi yog cov yam ntxwv ntawm SAS cables thiab SAS cables

SAS cable yog qhov chaw cia ntawm disk media yog cov cuab yeej tseem ceeb tshaj plaws, tag nrho cov ntaub ntawv thiab cov ntaub ntawv yuav tsum muab khaws cia rau hauv disk media. Kev nyeem ceev ntawm cov ntaub ntawv yog txiav txim siab los ntawm kev sib txuas interface ntawm disk media. Yav dhau los, peb ib txwm khaws peb cov ntaub ntawv los ntawm SCSI lossis SATA interfaces thiab hard drives. Nws yog vim muaj kev txhim kho sai ntawm SATA thev naus laus zis thiab ntau yam zoo uas ntau tus neeg yuav xav txog seb puas muaj txoj hauv kev los ua ke ntawm SATA thiab SCSI, kom qhov zoo ntawm ob qho tib si tuaj yeem ua si tib lub sijhawm. Hauv qhov no, SAS tau tshwm sim. Cov khoom siv sib txuas sib txuas tuaj yeem muab faib ua peb pawg loj, uas yog, high-end nruab nrab-kawg thiab ze-kawg (Nyob ze-Line). High-end cia li yog cov fiber ntau channel. Vim qhov kev sib kis ceev ceev ntawm Fiber channel, feem ntau high-end cia khoom siv fiber ntau tau siv rau lub peev xwm loj ntawm lub sijhawm khaws cia ntawm cov ntaub ntawv tseem ceeb ntawm cov haujlwm. Cov cuab yeej cia nruab nrab feem ntau yog SCSI cov cuab yeej, thiab nws tseem muaj keeb kwm ntev, tau siv hauv kev khaws cia loj ntawm kev lag luam-qib cov ntaub ntawv tseem ceeb. Cov ntawv luv li (SATA), nws yog siv rau kev khaws cia loj ntawm cov ntaub ntawv tsis tseem ceeb thiab npaj los hloov cov ntaub ntawv yav dhau los thaub qab siv daim kab xev. Qhov zoo tshaj plaws ntawm Fiber Channel cia cov khoom siv yog kev sib kis ceev, tab sis nws muaj tus nqi siab thiab yog ib qho nyuaj rau tswj; SCSI cov cuab yeej muaj kev nkag tau yooj yim thiab tus nqi nruab nrab, tab sis nws txuas ntxiv me ntsis, txhua daim npav SCSI interface txuas mus txog 15 (ib channel) lossis 30 (dual-channel) khoom siv. SATA yog ib qho kev txhim kho sai sai hauv xyoo tas los no. Nws qhov txiaj ntsig loj tshaj plaws yog tias nws pheej yig, thiab qhov nrawm tsis qis dua li SCSI interface. Nrog rau kev txhim kho thev naus laus zis, SATA cov ntaub ntawv nyeem ceev tau nce mus thiab dhau ntawm SCSI interface. Tsis tas li ntawd, raws li SATA lub hard disk tau txais pheej yig dua thiab kim dua, nws tuaj yeem maj mam siv rau cov ntaub ntawv thaub qab. Yog li kev lag luam ib txwm khaws cia vim tias xav txog qhov ua tau zoo thiab kev ruaj ntseg, nrog SCSI hard disk thiab fiber optic channel ua lub ntsiab cia platform, SATA feem ntau yog siv rau cov ntaub ntawv tsis tseem ceeb lossis desktop tus kheej lub computer, tab sis nrog kev nce ntawm SATA technology thiab SATA cov cuab yeej. paub tab, hom no tau hloov pauv, ntau thiab ntau tus neeg pib mob siab rau SATA qhov kev sib txuas ntawm cov ntaub ntawv khaws cia.
