I-PCIe vs SAS vs SATA: The Battle of Next-Generation Storage Interface Technologies

I-PCIe vs SAS vs SATA: The Battle of Next-Generation Storage Interface Technologies

Njengamanje, ama-hard disks okugcina angu-2.5-intshi/3.5-intshi embonini ikakhulukazi anezindawo ezintathu: i-PCIe, i-SAS ne-SATA. Ezicelweni zesikhungo sedatha, izixazululo zokuxhuma ezifana ne-MINI SAS 8087 kuya ku-4X SATA 7P Male cable kanye ne-MINI SAS 8087 kuya ku-SLIM SAS 8654 4I zisetshenziswa kakhulu. Esikhathini esedlule, ukuthuthukiswa kokuthuthukiswa kokuxhumana kwesikhungo sedatha empeleni kwakuqhutshwa izikhungo noma izinhlangano ezifana ne-IEEE noma i-OIF-CEI. Nokho, kuye kwenzeka ushintsho olukhulu namuhla. Ama-opharetha amakhulu esikhungo sedatha afana ne-Amazon, i-Apple, i-Facebook, i-Google ne-Microsoft manje ashayela ukuthuthukiswa kwezobuchwepheshe.

Mayelana ne-PCIe

I-PCIe ngokungangabazeki iyindinganiso yamabhasi okuthutha ethandwa kakhulu, futhi izibuyekezo zayo bezivame kakhulu eminyakeni yamuva nje. Yize ijubane lokuthuthukisa liye lashesha, izinguquko esizukulwaneni ngasinye se-PCIe zibaluleke kakhulu, ikakhulukazi ngomkhawulokudonsa ophindwe kabili isikhathi ngasinye nokugcina ukuhambisana nazo zonke izizukulwane ezedlule.

I-PCIe 6.0 injalo. Ngenkathi ibuyela emuva ihambisana ne-PCIe 5.0/4.0/3.0/2.0/1.0, izinga ledatha noma umkhawulokudonsa we-I/O uzophinda kabili futhi ube ngu-64 GT/s. Umkhawulokudonsa wendlela eyodwa wangempela we-PCIe 6.0 x1 ngu-8 GB/s, umkhawulokudonsa wendlela eyodwa we-PCIe 6.0 x16 ungu-128 GB/s, kanti umkhawulokudonsa ophindwe kabili ungu-256 GB/s. Lesi sikhombimsebenzisi esinesivinini esikhulu siphinde sanikeza izixazululo ezintsha zokuxhuma 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.

Mayelana ne-SAS
I-Serial Attached SCSI interface (Serial Attached SCSI, SAS) ubuchwepheshe be-SCSI besizukulwane esilandelayo. Njengama-hard drive e-Serial ATA (SATA) adumile njengamanje, i-SAS iphinde yamukela ubuchwepheshe be-serial ukuze kuzuzwe isivinini sokudlulisela okuphezulu futhi kuthuthukise isikhala sangaphakathi ngokufinyeza imigqa yokuxhuma. I-SAS iyisixhumi esibonakalayo esisha ngokuphelele esakhiwe ngemva kwesixhumi esibonakalayo se-SCSI esihambisanayo. Ezinhlelweni zesimanje zokugcina, izintambo zokuxhuma ezifana ne-MINI SAS 8087 kuya ku-8482 CABLE, i-MINI SAS 8087 kuya ku-4X SATA 7P ikhebula labesifazane, njll., adlala indima ebalulekile. Ikakhulukazi uhlelo lokuxhuma lwe-engeli yesokudla lwe-MINI SAS 8087 kuya ku-4X SATA 7P yekhebula le-right angle yowesifazane lidume kakhulu ezindaweni zeseva ezinezikhala ezilinganiselwe.

Mayelana ne-SATA

I-SATA imele i-Serial ATA (I-Serial Advanced Technology Attachment), eyaziwa nangokuthi i-serial ATA. Ukucaciswa kwe-hard drive interface ehlongozwa ngokuhlanganyela yi-Intel, IBM, Dell, APT, Maxtor kanye neSeagate.

Njengesixhumi esibonakalayo se-hard disk esisetshenziswa kakhulu emakethe yamanje, inzuzo enkulu yesixhumi esibonakalayo se-SATA 3.0 kufanele kube ukuvuthwa kwayo. Womabili ama-SSD ajwayelekile angu-2.5-intshi nama-HDD asebenzisa lesi sixhumanisi. Mayelana nezixazululo zokuxhuma, i-MINI SAS 8087 kuya ku-4X SATA 7P Female ene-Sideload inikeza isisombululo esilula sokufaka eceleni, kuyilapho i-MINI SAS 8087 kuya ku-4X SATA 7P yekhebula yowesifazane engele kwesokudla ilungele izimo ezinendawo elinganiselwe. Umkhawulokudonsa wokudluliswa kwethiyori ngu-6 Gbps. Nakuba inegebe elithile uma kuqhathaniswa nomkhawulokudonsa ongu-10 Gbps no-32 Gbps wesixhumi esibonakalayo esisha, ama-SSD avamile 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 nokuxhumana kwamanje, isikhombimsebenzisi se-PCI Express singanikeza ukudluliswa kwedatha okusheshayo nokubambezeleka okufushane, okwenza ngcono kakhulu ukusebenza kahle kanye nokwenza inzuzo kwezinhlangano. Izinzuzo zizoba ngokugqama kakhulu. Ngaso leso sikhathi, izixazululo zokuxhuma ezintsha ezifana ne-MINI SAS 8087 kuya ku-SAS SFF-8482 Intambo ye-Two-in-One kanye ne-MINI SAS 8087 kuya ku-Oculink SAS 8611 4I nazo zidlula imingcele yobuchwepheshe bokugcina. Ikakhulukazi ezindaweni zokugcina eziminyanisa kakhulu, imiklamo yesixhumi esine-engeli ekhethekile njenge-MINI SAS 8087 e-left-angled to 4X SATA 7P Female 90-Degree ixazulule izinkinga zezintambo.
