I-PCIe vs SAS vs SATA: Impi Yesizukulwane Esilandelayo I-Storage Interface Technologies

I-PCIe vs SAS vs SATA: Impi Yesizukulwane Esilandelayo I-Storage Interface Technologies

Njengamanje, ama-hard disk esitoreji angu-2.5-intshi/3.5-intshi embonini ikakhulukazi anezindawo ezintathu zokuxhuma: i-PCIe, i-SAS kanye ne-SATA. Ezinhlelweni zokusebenza zesikhungo sedatha, izixazululo zokuxhuma ezifana nekhebula le-MINI SAS 8087 kuya ku-4X SATA 7P Male kanye ne-MINI SAS 8087 kuya ku-SLIM SAS 8654 4I zisetshenziswa kabanzi. Esikhathini esidlule, ukuthuthukiswa kokuthuthukiswa kokuxhumana kwesikhungo sedatha empeleni kwakuqhutshwa yizikhungo noma izinhlangano ezifana ne-IEEE noma i-OIF-CEI. Kodwa-ke, kwenzeke ushintsho olukhulu kulezi zinsuku. Abaqhubi besikhungo sedatha abakhulu njenge-Amazon, i-Apple, i-Facebook, i-Google kanye ne-Microsoft manje baqhuba intuthuko yezobuchwepheshe.

Mayelana ne-PCIe

Akungabazeki ukuthi i-PCIe iyindinganiso yebhasi yokudlulisa ethandwa kakhulu, futhi izibuyekezo zayo bezivame kakhulu eminyakeni yamuva nje. Nakuba isivinini sokuthuthukisa siye sashesha, izinguquko esizukulwaneni ngasinye semininingwane ye-PCIe zibaluleke kakhulu, ikakhulukazi njengoba i-bandwidth iphindaphindeka kabili isikhathi ngasinye futhi igcina ukuhambisana nazo zonke izizukulwane zangaphambilini.

I-PCIe 6.0 ayihlukile. Nakuba ihambisana ne-PCIe 5.0/4.0/3.0/2.0/1.0, izinga ledatha noma i-bandwidth ye-I/O izophindeka kabili ibe yi-64 GT/s. I-bandwidth yangempela ye-one-way ye-PCIe 6.0 x1 ingu-8 GB/s, i-one-way bandwidth ye-PCIe 6.0 x16 ingu-128 GB/s, kanti i-bidirectional bandwidth ingu-256 GB/s. Lesi sixhumanisi sesivinini esikhulu siphinde saveza izixazululo ezintsha zokuxhumeka njengekhebula le-MCIO 8I kuya ku-2 OCuLink 4i, i-PCIe Slimline SAS 4.0 38-Pin SFF-8654 4i kuya ku-4 SATA 7-Pin Right-Angled Cable, njll.

Ngokuphathelene ne-SAS
I-Serial Attached SCSI interface (Serial Attached SCSI, SAS) ubuchwepheshe besizukulwane esilandelayo se-SCSI. Njengama-hard drive e-Serial ATA (SATA) adumile njengamanje, i-SAS iphinde isebenzise ubuchwepheshe obulandelanayo ukuze ifinyelele isivinini esiphezulu sokudlulisa futhi ithuthukise isikhala sangaphakathi ngokufinyeza imigqa yokuxhuma. I-SAS iyi-interface entsha ngokuphelele eyakhiwe ngemuva kwe-interface ye-SCSI efanayo. Ezinhlelweni zokugcina zesimanje, izintambo zokuxhuma ezifana ne-MINI SAS 8087 kuya ku-8482 CABLE, i-MINI SAS 8087 kuya ku-4X SATA 7P female cable, njll., zidlala indima ebalulekile. Ikakhulukazi uhlelo lokuxhuma lwe-engeli yesokudla lwe-MINI SAS 8087 kuya ku-4X SATA 7P female angle luthandwa kakhulu ezindaweni zeseva ezinesikhala esilinganiselwe.

Ngokuphathelene ne-SATA

I-SATA imele i-Serial ATA (Serial Advanced Technology Attachment), eyaziwa nangokuthi i-serial ATA. Iyincazelo ye-hard drive ephakanyiswe ngokubambisana yi-Intel, i-IBM, i-Dell, i-APT, i-Maxtor kanye ne-Seagate.

Njengesixhumi esibonakalayo sediski esisetshenziswa kakhulu emakethe yamanje, inzuzo enkulu yesixhumi esibonakalayo se-SATA 3.0 kufanele kube ukuvuthwa kwaso. Ama-SSD nama-HDD ajwayelekile angu-2.5 intshi asebenzisa lesi sixhumi esibonakalayo. Ngokuphathelene nezixazululo zokuxhuma, i-MINI SAS 8087 kuya ku-4X SATA 7P Female ene-Sideload inikeza isisombululo esilula sokufaka eceleni, kuyilapho ikhebula lesifazane le-MINI SAS 8087 kuya ku-4X SATA 7P elingakwesokudla lifanelekela izimo ezinesikhala esilinganiselwe. I-bandwidth yokudlulisa yethiyori ingu-6 Gbps. Nakuba inegebe elithile uma liqhathaniswa ne-bandwidth engu-10 Gbps kanye ne-32 Gbps yesixhumi esibonakalayo esisha, ama-SSD ajwayelekile angu-2.5 intshi angahlangabezana nezidingo zohlelo lokusebenza zansuku zonke zabasebenzisi abaningi, futhi isivinini sokufunda nokubhala esingaba ngu-500 MB/s sanele.

Inani ledatha emhlabeni we-inthanethi likhula ngokushesha. Uma kuqhathaniswa nezixhumi zamanje, isixhumi se-PCI Express singanikeza ukudluliswa kwedatha okusheshayo kanye nokubambezeleka okufushane, okuthuthukisa kakhulu ukusebenza kahle kanye nenzuzo yezinhlangano. Izinzuzo zizobonakala kakhulu. Ngesikhathi esifanayo, izixazululo zokuxhuma ezintsha njengekhebula le-MINI SAS 8087 kuya ku-SAS SFF-8482 Two-in-One kanye nekhebula le-MINI SAS 8087 kuya ku-Oculink SAS 8611 4I nazo zicindezela imingcele yobuchwepheshe bokugcina. Ikakhulukazi ezindaweni zokugcina ezinobuningi obukhulu, imiklamo yezixhumi ze-engeli ekhethekile njenge-MINI SAS 8087 Left-angle to 4X SATA 7P Female 90-Degree ixazulule izinkinga zokuxhuma.
