PCIe vs SAS vs SATA: Ntoa ea Next-Generation Storage Interface Technologies

Hajoale, li-hard disk tsa 2.5-inch/3.5-inch indastering li na le li-interfaces tse tharo: PCIe, SAS le SATA. Likopong tsa setsi sa data, litharollo tsa khokahano tse kang MINI SAS 8087 ho 4X SATA 7P Male cable le MINI SAS 8087 ho SLIM SAS 8654 4I li sebelisoa haholo. Nakong e fetileng, nts'etsopele ea ntlafatso ea li-interconnection tsa data center e ne e hlile e khannoa ke mekhatlo kapa mekhatlo e kang IEEE kapa OIF-CEI. Leha ho le joalo, ho etsahetse phetoho e khōlō matsatsing ana. Lits'ebetso tse kholo tsa setsi sa data tse kang Amazon, Apple, Facebook, Google le Microsoft li se li khanna nts'etsopele ea theknoloji.

Ha ho pelaelo hore PCIe ke eona e tsebahalang ka ho fetesisa maemo a libese, 'me lintlafatso tsa eona li bile teng khafetsa lilemong tsa morao tjena. Le hoja lebelo la ntlafatso le potlakile, liphetoho molokong o mong le o mong oa litlhaloso tsa PCIe li bohlokoa haholo, haholo-holo ha bandwidth e imena habeli nako le nako le ho boloka ho lumellana le meloko eohle e fetileng.

PCIe 6.0 le eona e joalo. Ha e ntse e khutlela morao e tsamaellana le PCIe 5.0/4.0/3.0/2.0/1.0, sekhahla sa data kapa I/O bandwidth e tla habeli hape ho 64 GT/s. Sebaka sa 'nete sa tsela e le' ngoe ea PCIe 6.0 x1 ke 8 GB/s, tsela e le 'ngoe ea PCIe 6.0 x16 ke 128 GB/s, le bandwidth ea bidirectional ke 256 GB/s. Khokahano ena ea lebelo le holimo e boetse e hlahisitse litharollo tse ncha tsa khokahano joalo ka thapo ea MCIO 8I ho 2 OCuLink 4i, PCIe Slimline SAS 4.0 38-Pin SFF-8654 4i ho 4 SATA 7-Pin Right-Angled Cable, joalo-joalo.

Mabapi le SAS
Sebopeho sa Serial Attached SCSI (Serial Attached SCSI, SAS) ke theknoloji ea SCSI ea moloko o latelang. Joalo ka li-hard drive tse tsebahalang hajoale tsa Serial ATA (SATA), SAS e boetse e sebelisa theknoloji ea serial ho fihlela lebelo le phahameng la phetisetso le ho ntlafatsa sebaka sa kahare ka ho khutsufatsa likhoele tsa khokahano. SAS ke sehokelo se secha ka ho felletseng se ntlafalitsoeng kamora sebopeho se tšoanang sa SCSI. Lits'ebetsong tsa sejoale-joale tsa polokelo, likhoele tsa likhokahano tse kang MINI SAS 8087 ho isa 8482 CABLE, MINI SAS 8087 ho isa 4X SATA 7P cable ea basali, joalo-joalo, li bapala karolo ea bohlokoa. Haholo-holo leano la khokahanyo la letsoho le letona la MINI SAS 8087 ho 4X SATA 7P thapo ea basali ea angle e nepahetseng e tumme haholo libakeng tsa seva tse nang le sebaka se lekanyelitsoeng.

Mabapi le SATA

SATA e emetse Serial ATA (Serial Advanced Technology Attachment), e tsejoang hape e le serial ATA. Ke sebopeho sa sebopeho sa hard drive se kopantsoeng ka kopanelo ke Intel, IBM, Dell, APT, Maxtor le Seagate.

Joalo ka sebopeho sa hard disk se sebelisoang haholo 'marakeng oa hajoale, monyetla o moholo oa sebopeho sa SATA 3.0 e lokela ho ba kholo ea eona. Ka bobeli li-SSD tse tloaelehileng tsa 2.5-inch le li-HDD li sebelisa sebopeho sena. Mabapi le tharollo ea khokahanyo, MINI SAS 8087 ho 4X SATA 7P Female e nang le Sideload e fana ka tharollo e bonolo ea ho kenya lehlakoreng, ha MINI SAS 8087 ho 4X SATA 7P ea thapo e nepahetseng ea basali e loketse maemo a nang le sebaka se fokolang. Tekanyo ea phetiso ea theory ke 6 Gbps. Le hoja e na le lekhalo le itseng ha le bapisoa le 10 Gbps le 32 Gbps bandwidth ea sebopeho se secha, li-SSD tse tloaelehileng tsa 2.5-inch li ka finyella litlhoko tsa letsatsi le letsatsi tsa basebelisi ba bangata, 'me lebelo la ho bala le ho ngola le ka bang 500 MB / s le lekane.

Palo ea data lefatšeng la Marang-rang e ntse e eketseha ka potlako. Ha ho bapisoa le li-interfaces tsa hajoale, sebopeho sa PCI Express se ka fana ka phetiso ea data e potlakileng le latency e khuts'oane, e ntlafatsa haholo ts'ebetso le phaello ea mekhatlo. Melemo e tla bonahala haholo. Ka nako e ts'oanang, litharollo tse ncha tsa khokahanyo tse kang MINI SAS 8087 ho SAS SFF-8482 Double-in-One cable le MINI SAS 8087 ho Oculink SAS 8611 4I le tsona li sutumelletsa meeli ea theknoloji ea polokelo. Haholo-holo libakeng tsa polokelo tse phahameng haholo, meralo ea li-angle-angle tse khethehileng tse kang MINI SAS 8087 Left-angled ho 4X SATA 7P Female 90-Degree e rarollotse mathata a marang-rang.
