Umahluko phakathi kwe-SAS kunye ne-SATA

Intsingiselo ye-SATA kunye ne-SAS

I-SATA, eyaziwa ngokuba yi-Serial Advanced Technology Attachment, i-interface yebhasi edibanisa i-adapter yebhasi yomkhosi kwi-hard drive.Kwi-2001, iKomiti ye-Serial ATA, eyenziwe ngabavelisi abakhulu abafana ne-Intel, i-APT, i-Dell, i-IBM, i-Seagate, kunye ne-Maxtor, yaseka ngokusemthethweni inkcazo ye-serial ATA 1.0, eyona nto ihamba phambili kwii-hard drives namhlanje nakwixesha elizayo.

SAS, ekwaziwa njengeUthotho oluncamatheleyo kwi-SCSI, sisizukulwana esitsha sobuchwepheshe be-SCSI esisebenzisa iteknoloji ye-serial ukufezekisa isantya esiphezulu sothumelo kunye nokuphucula indawo yangaphakathi ngokunciphisa imigca yokudibanisa.I-SAS lujongano olutsha kraca oluphuhliswe emva kojongano olunxuseneyo lwe-SCSI.Olu jongano lunokuphucula ukusebenza, ukufumaneka, kunye ne-scalability yenkqubo yokugcina, kunye nokubonelela ngokuhambelana ne-SATA hard drives.

Abasebenzisi abaninzi abaqhelananga kakhulu nee-SAS hard drives kunye ne-Sata hard drives.Ngapha koko, ii-hard drives zoomatshini zinokwahlulwa ikakhulu zibe zii-SATA hard drives kunye ne-SAS hard drives ngokwendlela yokujongana kwazo.

I-SAS hard drive lunxibelelwano olutsha kraca oluphuhliswe emva kojongano olunxuseneyo lwe-SCSI.I-node yokugcina i-hard disk ye-Sata iquka i-MCI yolawulo lwememori kunye nomlawuli we-SATA hard disk.2. Iimpawu ezahlukeneyo: I-SAS hard drive ithatha iteknoloji ye-serial, ekhokelela kwisantya esiphezulu sokudluliselwa.Unxibelelwano lwe-ATA hard disk luthatha iprotocol yeSATA, eyahlulahlulwe ngokwamaleko womzimba, umaleko wekhonkco, umaleko wothumelo, kunye nomyalelo womyalelo ngokwemisebenzi yawo.

Umahluko phakathi kwe-SATA kunye ne-SAS
1. Umahluko ophambili: I-SAS hard disk lujongano olutsha kraca oluphuhliswe emva kojongano olunxuseneyo lwe-SCSI.I-node yokugcina i-hard disk ye-Sata iquka i-MCI yolawulo lwememori kunye nomlawuli we-SATA hard disk.
2. Iimpawu ezahlukeneyo: ii-SAS hard drives zisebenzisa iteknoloji ye-serial ukufezekisa isantya esiphezulu sokudlulisa kunye nokuphucula indawo yangaphakathi ngokunciphisa imigca yokudibanisa.Unxibelelwano lwe-ATA hard disk luthatha iprotocol yeSATA, eyahlulahlulwe ngokwamaleko womzimba, umaleko wekhonkco, umaleko wothumelo, kunye nomyalelo womyalelo ngokwemisebenzi yawo.
3. Umahluko wenjongo: i-SAS hard drive: ukuphucula ukusebenza kakuhle, ukufumaneka, kunye nokunciphisa inkqubo yokugcina, kunye nokubonelela ngokuhambelana ne-SATA hard drives.I-hard drive ye-Sata ithatha indlela yokudibanisa i-serial, kwaye i-serial ye-ATA yebhasi isebenzisa izibonakaliso zewotshi ezifakwe ngaphakathi, ezinamandla okulungisa iimpazamo kunye neenzuzo zesakhiwo esilula kunye nenkxaso yokutshintsha okushushu.

Kwiimeko zesicelo, ii-SATA hard drives zisetyenziselwa ukugcinwa komthamo ophezulu.Xa kuthelekiswa nebanga lasekhaya leSATA, ibakala leshishini leSATA hard drives sele linengqibelelo eyaneleyo yedatha kunye nokhuseleko lwedatha, kodwa kusekho umsantsa kwi-IO processing xa kuthelekiswa neSAS.I-SAS hard drives zisetyenziswa kakhulu kwizicelo zenqanaba leshishini, ezinokuhlangabezana nokusebenza okuphezulu kunye nokuthembeka okuphezulu kwezicelo.
