I-PCIe vs SAS vs SATA: Imfazwe yeTekhnoloji yoLondolozo lweSizukulwana esilandelayo

Okwangoku, ii-hard disk zokugcina ezizii-intshi eziyi-2.5/3.5 kwishishini ikakhulu zineendawo ezintathu zokunxibelelana: i-PCIe, i-SAS kunye ne-SATA. Kwizicelo zeziko ledatha, izisombululo zonxibelelwano ezifana ne-MINI SAS 8087 ukuya kwi-4X SATA 7P Male cable kunye ne-MINI SAS 8087 ukuya kwi-SLIM SAS 8654 4I zisetyenziswa kakhulu. Ngaphambili, uphuhliso lokuphuculwa kokunxibelelana kweziko ledatha lwaluqhutywa zizikhungo okanye imibutho efana ne-IEEE okanye i-OIF-CEI. Nangona kunjalo, kukho utshintsho olukhulu kule mihla. Abaqhubi abakhulu beziko ledatha abafana ne-Amazon, i-Apple, i-Facebook, i-Google kunye ne-Microsoft ngoku baqhuba uphuhliso lwetekhnoloji.

Malunga ne-PCIe

I-PCIe ngokungathandabuzekiyo yeyona bhasi idumileyo yokudlulisa idatha, kwaye uhlaziyo lwayo luye lwanda kakhulu kwiminyaka yakutshanje. Nangona isantya sokuphucula sikhawulezile, utshintsho kwisizukulwana ngasinye seenkcukacha ze-PCIe lubaluleke kakhulu, ingakumbi xa i-bandwidth iphindaphindeka kabini ngalo lonke ixesha kwaye igcina ukuhambelana nazo zonke izizukulwana zangaphambili.

I-PCIe 6.0 ayifani nayo. Nangona ihambelana ne-PCIe 5.0/4.0/3.0/2.0/1.0, izinga ledatha okanye i-bandwidth ye-I/O iya kuphinda kabini ukuya kwi-64 GT/s. I-bandwidth yokwenyani ye-PCIe 6.0 x1 yi-8 GB/s, i-bandwidth yokwenyani ye-PCIe 6.0 x16 yi-128 GB/s, kwaye i-bandwidth yokujonga kabini yi-256 GB/s. Olu jongano olukhawulezayo lukwavelise izisombululo ezintsha zonxibelelwano ezifana nentambo ye-MCIO 8I ukuya kwi-2 OCuLink 4i, i-PCIe Slimline SAS 4.0 38-Pin SFF-8654 4i ukuya kwi-4 SATA 7-Pin Right-Angled Cable, njl.

Ngokuphathelele i-SAS
I-Serial Attached SCSI interface (Serial Attached SCSI, SAS) yiteknoloji yesizukulwana esilandelayo se-SCSI. Njengee-hard drive ze-Serial ATA (SATA) ezidumileyo ngoku, i-SAS ikwasebenzisa iteknoloji ye-serial ukuze ifikelele kwisantya esiphezulu sokudlulisa kwaye iphucule indawo yangaphakathi ngokunciphisa imigca yoqhagamshelo. I-SAS yi-interface entsha ngokupheleleyo eyenziwe emva kwe-interface ye-SCSI efanayo. Kwiinkqubo zokugcina zanamhlanje, iintambo zoqhagamshelo ezifana ne-MINI SAS 8087 ukuya kwi-8482 CABLE, i-MINI SAS 8087 ukuya kwi-4X SATA 7P female cable, njl.njl., zidlala indima ebalulekileyo. Ingakumbi i-scheme yoqhagamshelo lwe-engile yasekunene ye-MINI SAS 8087 ukuya kwi-4X SATA 7P right angle female cable ithandwa kakhulu kwiindawo zeseva ezinesithuba esincinci.

Ngokuphathelele i-SATA

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

Njengeyona ndawo isetyenziswa kakhulu kwi-hard disk kwimarike yangoku, eyona nzuzo inkulu ye-SATA 3.0 interface kufuneka ibe kukuvuthwa kwayo. Zombini ii-SSD eziqhelekileyo ze-2.5-intshi kunye nee-HDD zisebenzisa le ndawo. Ngokuphathelele izisombululo zonxibelelwano, i-MINI SAS 8087 ukuya kwi-4X SATA 7P Female ene-Sideload inika isisombululo esilula sokufaka ecaleni, ngelixa intambo ye-MINI SAS 8087 ukuya kwi-4X SATA 7P engile yasekunene ifanelekile kwiimeko ezinesithuba esincinci. I-bandwidth yokudlulisa yethiyori yi-6 Gbps. Nangona inesithuba esithile xa ithelekiswa ne-bandwidth ye-10 Gbps kunye ne-32 Gbps ye-interface entsha, ii-SSD eziqhelekileyo ze-2.5-intshi zinokuhlangabezana neemfuno zesicelo semihla ngemihla zabasebenzisi abaninzi, kwaye isantya sokufunda nokubhala esimalunga ne-500 MB/s sanele.

Inani ledatha kwihlabathi le-Intanethi liyanda ngokukhawuleza. Xa kuthelekiswa ne-interfaces zangoku, i-PCI Express interface inokubonelela ngokudluliselwa kwedatha ngokukhawuleza kunye nokubambezeleka okufutshane, okuphucula kakhulu ukusebenza kakuhle kunye nenzuzo yemibutho. Iingenelo ziya kuba zibonakala ngakumbi. Kwangaxeshanye, izisombululo ezintsha zoqhagamshelo ezifana ne-MINI SAS 8087 ukuya kwi-SAS SFF-8482 Two-in-One cable kunye ne-MINI SAS 8087 ukuya kwi-Oculink SAS 8611 4I nazo zityhala imida yetekhnoloji yokugcina. Ingakumbi kwiindawo zokugcina ezinoxinano olukhulu, uyilo lwezixhumi ze-engile ekhethekileyo ezifana ne-MINI SAS 8087 Left-angled to 4X SATA 7P Female 90-Degree zisombulule iingxaki zocingo.
