MINI SAS HD SFF-8087 rau 4X SATA Txoj Cai Lub Siab Ceev Server Sab Hauv Kev Sib Txuas Hlau Harness

Cov yam ntxwv ntawm SAS cables thiab SAS cables yog dab tsi?

SAS cable yog qhov chaw khaws cia ntawm cov disk media yog qhov tseem ceeb tshaj plaws, txhua cov ntaub ntawv thiab cov ntaub ntawv yuav tsum khaws cia rau ntawm cov disk media. Qhov ceev nyeem ntawm cov ntaub ntawv yog txiav txim siab los ntawm qhov sib txuas ntawm cov 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 technology thiab ntau yam zoo uas ntau tus neeg yuav xav txog seb puas muaj txoj hauv kev los sib xyaw ua ke ob qho tib si SATA thiab SCSI, yog li qhov zoo ntawm ob qho tib si tuaj yeem ua si tib lub sijhawm. Hauv qhov no, SAS tau tshwm sim. Cov khoom siv khaws cia networked tuaj yeem faib ua peb pawg loj, uas yog, high-end nruab nrab-kawg thiab ze-kawg (Near-Line). Cov khoom siv khaws cia high-end feem ntau yog Fibre channel. Vim yog qhov ceev ceev ntawm Fibre channel, feem ntau cov khoom siv khaws cia optical fiber ntau yog siv rau qhov muaj peev xwm loj tiag tiag khaws cia ntawm cov ntaub ntawv tseem ceeb ntawm cov haujlwm. Cov khoom siv khaws cia nruab nrab yog SCSI cov khoom siv, thiab nws kuj muaj keeb kwm ntev, siv rau hauv kev khaws cia ntawm cov ntaub ntawv tseem ceeb ntawm kev lag luam. Lub npe luv ua (SATA), nws yog siv rau kev khaws cia cov ntaub ntawv tsis tseem ceeb thiab yog siv los hloov cov ntaub ntawv thaub qab yav dhau los siv daim kab xev. Qhov zoo tshaj plaws ntawm Fibre Channel cia khoom siv yog kev sib kis ceev, tab sis nws muaj tus nqi siab thiab nyuaj rau kev tswj hwm; SCSI cov khoom siv muaj kev nkag mus sai thiab tus nqi nruab nrab, tab sis nws tsis ntev dua me ntsis, txhua daim npav SCSI interface txuas txog li 15 (ib txoj kab) lossis 30 (ob txoj kab) cov khoom siv. SATA yog ib qho thev naus laus zis uas tab tom loj hlob sai hauv xyoo tas los no. Nws qhov zoo tshaj plaws yog tias nws pheej yig, thiab qhov ceev tsis qeeb dua li SCSI interface. Nrog rau kev txhim kho thev naus laus zis, SATA qhov kev nyeem ntawv ceev tau los txog thiab dhau SCSI interface. Tsis tas li ntawd, vim SATA lub hard disk pheej yig dua thiab kim dua, nws tuaj yeem siv rau kev thaub qab cov ntaub ntawv. Yog li ntawd, cov chaw cia khoom lag luam ib txwm muaj vim tias xav txog kev ua tau zoo thiab kev ruaj khov, nrog SCSI hard disk thiab fiber optic channel ua lub platform cia khoom tseem ceeb, SATA feem ntau siv rau cov ntaub ntawv tsis tseem ceeb lossis lub khoos phis tawj desktop, tab sis nrog kev nce ntawm SATA thev naus laus zis thiab SATA cov khoom siv paub tab, hom no tau hloov pauv, ntau thiab ntau tus neeg pib them sai sai rau SATA txoj kev sib txuas cov ntaub ntawv cia khoom no.
