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 disks osungira 2.5-inchi / 3.5-inchi pamsika amakhala ndi mawonekedwe atatu: PCIe, SAS ndi SATA. M'mapulogalamu a data center, njira zolumikizirana monga MINI SAS 8087 mpaka 4X SATA 7P Male chingwe ndi MINI SAS 8087 ku SLIM SAS 8654 4I zimagwiritsidwa ntchito kwambiri. M'mbuyomu, chitukuko cha kukweza kwa data center interconnection upgrades kwenikweni chinali choyendetsedwa ndi mabungwe kapena mabungwe monga IEEE kapena OIF-CEI. Komabe, kusintha kwakukulu kwachitika masiku ano. Ogwiritsa ntchito ma data akuluakulu monga Amazon, Apple, Facebook, Google ndi Microsoft tsopano akuyendetsa chitukuko chaukadaulo.

Za PCIe

PCIe mosakayikira ndiye mulingo wodziwika kwambiri wamabasi, ndipo zosintha zake zachitika pafupipafupi mzaka zaposachedwa. Ngakhale kuti liwiro la kukweza kwakula, kusintha kwa m'badwo uliwonse wa PCIe ndikofunika kwambiri, makamaka ndi bandwidth kuwirikiza kawiri nthawi iliyonse ndikusunga kugwirizana ndi mibadwo yonse yam'mbuyo.

PCIe 6.0 ndi chimodzimodzi. Ngakhale kubwerera kumbuyo kumagwirizana ndi PCIe 5.0/4.0/3.0/2.0/1.0, kuchuluka kwa data kapena I/O bandwidth kudzawirikizanso mpaka 64 GT/s. Chingwe chenicheni cha njira imodzi ya PCIe 6.0 x1 ndi 8 GB/s, njira imodzi ya PCIe 6.0 x16 ndi 128 GB/s, ndipo bandwidth ya bidirectional ndi 256 GB/s. Mawonekedwe othamanga kwambiriwa aperekanso njira zatsopano zolumikizirana monga MCIO 8I mpaka 2 OCuLink 4i chingwe, PCIe Slimline SAS 4.0 38-Pin SFF-8654 4i mpaka 4 SATA 7-Pin Right-Angled Cable, etc.

Pankhani ya SAS
Mawonekedwe a Serial Attached SCSI (Serial Attached SCSI, SAS) ndiukadaulo wam'badwo wotsatira wa SCSI. Monga ma hard drive odziwika a Serial ATA (SATA), SAS imagwiritsanso ntchito ukadaulo wa serial kuti ikwaniritse kuthamanga kwambiri ndikuwongolera malo amkati mwa kufupikitsa mizere yolumikizira. SAS ndi mawonekedwe atsopano opangidwa pambuyo pa mawonekedwe ofanana a SCSI. M'makina amakono osungira, 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 mbali yakumanja ya MINI SAS 8087 mpaka 4X SATA 7P chingwe chachikazi cha ngodya yakumanja ndiyotchuka kwambiri m'malo a seva okhala ndi malo ochepa.

Pankhani ya SATA

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

Monga mawonekedwe a hard disk omwe amagwiritsidwa ntchito kwambiri pamsika wamakono, mwayi waukulu wa mawonekedwe a SATA 3.0 uyenera kukhala kukhwima kwake. Ma SSD wamba a 2.5-inch ndi ma HDD amagwiritsa ntchito mawonekedwewa. Pankhani yamayankho olumikizirana, MINI SAS 8087 mpaka 4X SATA 7P Female yokhala ndi Sideload imapereka njira yabwino yolowera mbali, pomwe MINI SAS 8087 mpaka 4X SATA 7P chingwe chachikazi chakumanja ndi choyenera pazithunzi zomwe zili ndi malo ochepa. Theoretical transmission bandwidth ndi 6 Gbps. Ngakhale ili ndi kusiyana kwina poyerekeza ndi 10 Gbps ndi 32 Gbps bandwidth ya mawonekedwe atsopano, ma SSD wamba a 2.5-inch amatha kukwaniritsa zosowa za tsiku ndi tsiku za ogwiritsa ntchito ambiri, ndipo liwiro lowerenga ndi kulemba la 500 MB / s ndilokwanira.

Kuchuluka kwa data pa intaneti kukuchulukirachulukira. Poyerekeza ndi mawonekedwe apano, mawonekedwe a PCI Express atha kupereka kutumiza kwa data mwachangu komanso latency yaifupi, kuwongolera bwino magwiridwe antchito ndi phindu la mabungwe. Ubwino wake udzakhala waukulu kwambiri. Nthawi yomweyo, njira zolumikizirana zatsopano monga MINI SAS 8087 kupita ku SAS SFF-8482 Chingwe cha Awiri-mu-Mmodzi ndi MINI SAS 8087 kupita ku Oculink SAS 8611 4I ndikukankhiranso malire aukadaulo wosungira. Makamaka m'malo osungiramo zinthu zakale kwambiri, mapangidwe apadera olumikizira ngongole monga MINI SAS 8087 Left-angled to 4X SATA 7P Female 90-Degree athetsa mavuto a waya.
