PCIe vs SAS vs SATA: Nkhondo ya Next-Generation Storage Interface Technologies

PCIe vs SAS vs SATA: Nkhondo ya Next-Generation Storage Interface Technologies

Pakadali pano, ma hard disk osungira a mainchesi 2.5/3.5 omwe ali mumakampaniwa ali ndi ma interfaces atatu: PCIe, SAS ndi SATA. Mu mapulogalamu a malo osungira deta, njira zolumikizira monga MINI SAS 8087 mpaka 4X SATA 7P Male cable ndi MINI SAS 8087 mpaka SLIM SAS 8654 4I zimagwiritsidwa ntchito kwambiri. Kale, chitukuko cha kusintha kwa kulumikizana kwa malo osungira deta chinali choyendetsedwa ndi mabungwe kapena mabungwe monga IEEE kapena OIF-CEI. Komabe, kusintha kwakukulu kwachitika masiku ano. Ogwira ntchito akuluakulu a malo osungira deta monga Amazon, Apple, Facebook, Google ndi Microsoft tsopano akuyendetsa chitukuko chaukadaulo.

Zokhudza PCIe

Mosakayikira PCIe ndiye muyezo wotchuka kwambiri wa mabasi otumizira ma transmission, ndipo zosintha zake zakhala zikuchitika kwambiri m'zaka zaposachedwa. Ngakhale kuti liwiro la kukweza lawonjezeka, kusintha kwa mibadwo yonse ya ma PCIe specifications n'kofunika kwambiri, makamaka chifukwa chakuti bandwidth imawonjezeka kawiri nthawi iliyonse ndikusunga mgwirizano ndi mibadwo yonse yam'mbuyomu.

PCIe 6.0 si yosiyana. Ngakhale kuti imagwirizana ndi PCIe 5.0/4.0/3.0/2.0/1.0, kuchuluka kwa deta kapena bandwidth ya I/O kudzawonjezekanso kufika pa 64 GT/s. Bandwidth yeniyeni ya PCIe 6.0 x1 ndi 8 GB/s, bandwidth ya PCIe 6.0 x16 ndi 128 GB/s, ndipo bandwidth ya bidirectional ndi 256 GB/s. Ma interface othamanga kwambiri awa aperekanso njira zatsopano zolumikizira monga chingwe cha MCIO 8I kupita ku 2 OCuLink 4i, PCIe Slimline SAS 4.0 38-Pin SFF-8654 4i kupita ku 4 SATA 7-Pin Right-Angled Cable, ndi zina zotero.

Ponena za SAS
Ma interface a Serial Attached SCSI (Serial Attached SCSI, SAS) ndi ukadaulo wa SCSI wa m'badwo wotsatira. Monga ma hard drive otchuka a Serial ATA (SATA) omwe alipo pano, SAS imagwiritsanso ntchito ukadaulo wa serial kuti ikwaniritse liwiro lalikulu la kutumiza ndikuwongolera malo amkati mwa kufupikitsa mizere yolumikizira. SAS ndi mawonekedwe atsopano opangidwa pambuyo pa mawonekedwe ofanana a SCSI. Mu makina osungira amakono, zingwe zolumikizira monga MINI SAS 8087 mpaka 8482 CABLE, MINI SAS 8087 mpaka 4X SATA 7P chingwe chachikazi, ndi zina zotero, zimagwira ntchito yofunika kwambiri. Makamaka njira yolumikizira ya MINI SAS 8087 mpaka 4X SATA 7P chingwe chachikazi cha right angle ndi yotchuka kwambiri m'malo omwe ali ndi malo ochepa.

Ponena za SATA

SATA imayimira Serial ATA (Serial Advanced Technology Attachment), yomwe imadziwikanso kuti serial ATA. Ndi mawonekedwe a hard drive omwe amaperekedwa pamodzi ndi Intel, IBM, Dell, APT, Maxtor ndi Seagate.

Popeza ndi malo ogwiritsira ntchito kwambiri pa hard disk pamsika wamakono, ubwino waukulu wa SATA 3.0 interface uyenera kukhala kukhwima kwake. Ma SSD wamba a 2.5-inch ndi ma HDD amagwiritsa ntchito mawonekedwe awa. Ponena za njira zolumikizira, MINI SAS 8087 mpaka 4X SATA 7P Female yokhala ndi Sideload imapereka njira yosavuta yolowera mbali, pomwe chingwe chachikazi cha MINI SAS 8087 mpaka 4X SATA 7P chakumanja chimagwira ntchito bwino pazochitika zokhala ndi malo ochepa. Bandwidth yotumizira deta ndi 6 Gbps. Ngakhale ili ndi kusiyana kwina poyerekeza ndi bandwidth ya 10 Gbps ndi 32 Gbps ya mawonekedwe atsopano, ma SSD wamba a 2.5-inch amatha kukwaniritsa zosowa za ogwiritsa ntchito tsiku ndi tsiku, ndipo liwiro lowerenga ndi kulemba la pafupifupi 500 MB/s ndilokwanira.

Kuchuluka kwa deta pa intaneti kukukwera mofulumira. Poyerekeza ndi ma interfaces omwe alipo pano, mawonekedwe a PCI Express amatha kupereka kutumiza deta mwachangu komanso kuchedwa kwakanthawi, zomwe zimapangitsa kuti mabungwe azigwira bwino ntchito komanso phindu. Ubwino wake udzakhala wodziwika kwambiri. Nthawi yomweyo, njira zatsopano zolumikizirana monga chingwe cha MINI SAS 8087 kupita ku SAS SFF-8482 Two-in-One ndi MINI SAS 8087 kupita ku Oculink SAS 8611 4I zikukankhiranso malire a ukadaulo wosungira. Makamaka m'malo osungira zinthu zambiri, mapangidwe a cholumikizira chapadera monga MINI SAS 8087 Left-angled to 4X SATA 7P Female 90-Degree athetsa mavuto a mawaya.
