I-PCIe vs SAS vs SATA: Idabi leSizukulwana esilandelayo soGcino lweTekhnoloji

Okwangoku, i-2.5-intshi / i-3.5-intshi yokugcina i-hard disks kwi-industry ikakhulu ine-interfaces ezintathu: i-PCIe, i-SAS kunye ne-SATA. Kwizicelo zeziko ledatha, izisombululo zoqhagamshelwano ezifana ne-MINI SAS 8087 ukuya kwi-4X SATA 7P Intambo yoBudoda kunye ne-MINI SAS 8087 ukuya kwi-SLIM SAS 8654 4I zisetyenziswa ngokubanzi. Kwixesha elidlulileyo, uphuhliso lokuphuculwa kweziko loqhagamshelwano lwedatha ngokwenene luqhutywa ngamaziko okanye imibutho efana ne-IEEE okanye i-OIF-CEI. Nangona kunjalo, kukho utshintsho oluphawulekayo namhlanje. Abaqhubi abakhulu bedatha abanjengoAmazon, Apple, Facebook, Google kunye neMicrosoft ngoku baqhuba uphuhliso lwetekhnoloji.

Malunga PCIe

I-PCIe ngokungathandabuzekiyo ngowona mgangatho webhasi wothumelo odumileyo, kwaye uhlaziyo lwayo beluqhelekile kwiminyaka yakutshanje. Nangona isantya sokuphucula siye sakhawuleza, utshintsho kwisizukulwana ngasinye se-PCIe lubaluleke kakhulu, ngakumbi nge-bandwidth ephindwe kabini ngexesha ngalinye kunye nokugcina ukuhambelana nazo zonke izizukulwana ezidlulileyo.

PCIe 6.0 akukho ngaphandle. Ngelixa umva uhambelana ne-PCIe 5.0/4.0/3.0/2.0/1.0, izinga ledatha okanye i-I/O bandwidth iya kuphinda kabini kwakhona kwi-64 GT/s. I-bandwidth yendlela enye ye-PCIe 6.0 x1 yi-8 GB / s, i-bandwidth yendlela enye ye-PCIe 6.0 x16 yi-128 GB / s, kunye ne-bidirectional bandwidth yi-256 GB / s. Olu jongano olunesantya esiphezulu luye lwavelisa izisombululo ezintsha zonxibelelwano ezifana ne-MCIO 8I ukuya kwi-2 OCuLink 4i cable, i-PCIe Slimline SAS 4.0 38-Pin SFF-8654 4i ukuya kwi-4 SATA 7-Pin Right-Angled Cable, njl.

Ngokumalunga ne-SAS
I-Serial Attached interface ye-SCSI (i-Serial Attached SCSI, i-SAS) iteknoloji ye-SCSI yesizukulwana esilandelayo. Kanye njengee-hard drives ze-Serial ATA (SATA) ezidumileyo ngoku, i-SAS ikwamkele itekhnoloji ye-serial ukuphumeza isantya esiphezulu sothumelo kunye nokuphucula indawo yangaphakathi ngokunciphisa imigca yoqhagamshelo. I-SAS lujongano olutsha ngokupheleleyo oluphuhliswe emva kojongano olunxuseneyo lwe-SCSI. Kwiinkqubo zokugcina zale mihla, iintambo zoqhagamshelo ezifana ne-MINI SAS 8087 ukuya kwi-8482 CABLE, i-MINI SAS 8087 ukuya kwi-4X SATA 7P intambo yabasetyhini, njl. njl., idlala indima ebalulekileyo. Ngokukodwa iskimu sokuqhagamshelwa kwe-engile-engile ye-MINI SAS 8087 ukuya kwi-4X SATA 7P intambo yasekunene yabasetyhini ithandwa kakhulu kwiimo zeseva ezinendawo encinci.

Ngokumalunga neSATA

I-SATA imele i-Serial ATA (i-Serial Advanced Technology Attachment), ekwaziwa ngokuba yi-serial ATA. Yinkcazo ye-hard drive interface ecetywe ngokudibeneyo yi-Intel, i-IBM, i-Dell, i-APT, i-Maxtor kunye ne-Seagate.

Njengoko i-hard disk interface esetyenziswa kakhulu kwimarike yangoku, inzuzo enkulu ye-SATA 3.0 interface kufuneka ibe kukuvuthwa kwayo. Zombini eziqhelekileyo i-2.5-intshi ye-SSD kunye nee-HDDs zisebenzisa le interface. Ngokumalunga nezisombululo zoqhagamshelwano, i-MINI SAS 8087 ukuya kwi-4X SATA 7P Female ene-Sideload ibonelela ngesisombululo esifanelekileyo sokufakela ecaleni, ngelixa i-MINI SAS 8087 ukuya kwi-4X SATA 7P ye-right-angle female cable ifanelekile kwiimeko ezinendawo encinci. I-bandwidth yothumelo lwethiyori yi-6 Gbps. Nangona ine-gap ethile xa kuthelekiswa ne-10 Gbps kunye ne-32 Gbps bandwidth ye-interface entsha, ii-SSD eziqhelekileyo ze-2.5-intshi zinokuhlangabezana neemfuno zesicelo semihla ngemihla yabasebenzisi abaninzi, kwaye isantya sokufunda nokubhala malunga ne-500 MB / s yanele.

Isixa sedatha kwihlabathi le-Intanethi sikhula ngokukhawuleza. Xa kuthelekiswa ne-interfaces yangoku, i-interface ye-PCI Express inokubonelela ngokukhawuleza ukuhanjiswa kwedatha kunye ne-latency emfutshane, ukuphucula kakhulu ukusebenza kakuhle kunye nenzuzo yemibutho. Iinzuzo ziya kuphawuleka ngakumbi. Kwangaxeshanye, izisombululo zoqhagamshelo ezintsha ezifana ne-MINI SAS 8087 ukuya kwi-SAS SFF-8482 intambo ye-Two-in-One kunye ne-MINI SAS 8087 ukuya kwi-Oculink SAS 8611 4I nazo zityhala imida yogcino lweteknoloji. Ngokukodwa kwiindawo zokugcina ezinoxinano oluphezulu, idizayini yokudibanisa i-angle ekhethekileyo efana ne-MINI SAS 8087 I-Left-angled ukuya kwi-4X SATA 7P Female 90-Degree iye yasombulula iingxaki zocingo.
