Kusiyana Pakati pa SAS ndi SATA

Tanthauzo la SATA ndi SAS

SATA, yomwe imadziwikanso kuti Serial Advanced Technology Attachment, ndi mawonekedwe a mabasi omwe amalumikiza adaputala ya basi yolowera ku hard drive.Mu 2001, Komiti ya Serial ATA, yopangidwa ndi opanga akuluakulu monga Intel, APT, Dell, IBM, Seagate, ndi Maxtor, adakhazikitsa ndondomeko ya Serial ATA 1.0, yomwe ndi njira yodziwika bwino yopangira ma hard drive lero ndi mtsogolo.

SAS, yomwe imadziwikanso kutiSeri Yophatikizidwa ndi SCSI, ndi mbadwo watsopano waukadaulo wa SCSI womwe umagwiritsa ntchito ukadaulo wapamwamba kwambiri kuti ukwaniritse kuthamanga kwambiri komanso kuwongolera malo amkati mwa kufupikitsa mizere yolumikizira.SAS ndi mawonekedwe atsopano opangidwa pambuyo polumikizirana SCSI.Mawonekedwewa amatha kupititsa patsogolo magwiridwe antchito, kupezeka, ndi scalability ya makina osungira, ndikupereka kuyanjana ndi ma hard drive a SATA.

Ogwiritsa ntchito ambiri sadziwa bwino ma hard drive a SAS ndi ma Sata hard drive.M'malo mwake, ma hard drive amawotchi amatha kugawidwa makamaka kukhala ma hard drive a SATA ndi ma hard drive a SAS molingana ndi mawonekedwe awo.

SAS hard drive ndi mawonekedwe atsopano opangidwa pambuyo pa mawonekedwe ofanana a SCSI.Sata hard disk yosungirako node imakhala ndi mawonekedwe owongolera kukumbukira MCI ndi chowongolera cha SATA hard disk.2. Makhalidwe osiyanasiyana: The SAS hard drive imatenga ukadaulo wa serial, zomwe zimapangitsa kuti pakhale kuthamanga kwambiri.Kuyankhulana kwa ATA hard disk kumatengera protocol ya SATA, yomwe imagawidwa kukhala wosanjikiza, wosanjikiza, wosanjikiza, ndi wosanjikiza wolamula malinga ndi ntchito zake.

Kusiyana pakati pa SATA ndi SAS
1. Kusiyana kwakukulu: SAS hard disk ndi mawonekedwe atsopano opangidwa pambuyo pa mawonekedwe ofanana a SCSI.Sata hard disk yosungirako node imakhala ndi mawonekedwe owongolera kukumbukira MCI ndi chowongolera cha SATA hard disk.
2. Makhalidwe osiyanasiyana: Ma hard drive a SAS amagwiritsa ntchito ukadaulo wa seriyo kuti akwaniritse kuthamanga kwambiri ndikuwongolera malo amkati mwa kufupikitsa mizere yolumikizira.Kuyankhulana kwa ATA hard disk kumatengera protocol ya SATA, yomwe imagawidwa kukhala wosanjikiza, wosanjikiza, wosanjikiza, ndi wosanjikiza wolamula malinga ndi ntchito zake.
3. Kusiyana kwa cholinga: SAS hard drive: kupititsa patsogolo mphamvu, kupezeka, ndi scalability ya makina osungira, komanso kupereka kugwirizanitsa ndi SATA hard drives.Sata hard drive imagwiritsa ntchito njira yolumikizira serial, ndipo basi ya ATA imagwiritsa ntchito mawotchi ophatikizidwa, omwe ali ndi mphamvu zowongolera zolakwika komanso zabwino zamapangidwe osavuta ndikuthandizira kusinthana kotentha.

M'malo ogwiritsira ntchito, ma hard drive a SATA nthawi zambiri amagwiritsidwa ntchito posungira kwambiri.Poyerekeza ndi giredi yakunyumba ya SATA, ma hard drive amtundu wa SATA ali kale ndi kukhulupirika kokwanira kwa data ndi chitetezo cha data, komabe pali kusiyana pakukonza kwa IO poyerekeza ndi SAS.Ma hard drive a SAS amagwiritsidwa ntchito kwambiri pamabizinesi, omwe amatha kukumana ndi magwiridwe antchito apamwamba komanso odalirika kwambiri.
