PCIe vs SAS vs SATA: ʻO ke kaua o nā ʻenehana hoʻopaʻa ʻana o ka hanauna hou
I kēia manawa, ʻo ka 2.5-inch/3.5-inch storage hard disks i ka ʻoihana he ʻekolu mau pilina: PCIe, SAS a me SATA. Ma nā noi kikowaena data, hoʻohana nui ʻia nā hoʻonā pili e like me MINI SAS 8087 a i 4X SATA 7P Male cable a me MINI SAS 8087 i SLIM SAS 8654 4I. I ka wā ma mua, ua alakaʻi maoli ʻia ka hoʻomohala ʻana i ka hoʻonui ʻana i nā kikowaena kikowaena data e nā hui a i ʻole nā hui e like me IEEE a i ʻole OIF-CEI. Eia naʻe, ua hoʻololi nui ʻia i kēia mau lā. ʻO nā mea hoʻohana kikowaena data nui e like me Amazon, Apple, Facebook, Google a me Microsoft ke hoʻokele nei i ka hoʻomohala ʻenehana.
E pili ana iā PCIe
ʻAʻole kānalua ʻo PCIe ka maʻamau kaʻa kaʻa hoʻouna kaulana loa, a ua hoʻonui pinepine ʻia kāna mau mea hou i nā makahiki i hala. ʻOiai ua wikiwiki ka wikiwiki o ka hoʻonui ʻana, ʻoi aku ka nui o nā loli i kēlā me kēia hanauna o ka kikoʻī PCIe, ʻoi aku hoʻi me ka pālua ʻana o ka bandwidth i kēlā me kēia manawa a me ka mālama ʻana i ka launa pū me nā hanauna mua.
ʻAʻole ʻokoʻa ka PCIe 6.0. ʻOiai ʻo ka hoʻi hope ʻana me PCIe 5.0/4.0/3.0/2.0/1.0, e pālua hou ka helu data a i ʻole I/O bandwidth i 64 GT/s. ʻO ka bandwidth hoʻokahi ala maoli o PCIe 6.0 x1 he 8 GB/s, ʻo ka bandwidth hoʻokahi ala o PCIe 6.0 x16 ʻo 128 GB/s, a ʻo ka bandwidth bidirectional he 256 GB/s. Ua hāʻawi ʻia kēia ʻano kiʻekiʻe kiʻekiʻe i nā hoʻonā pili hou e like me MCIO 8I i 2 OCuLink 4i cable, PCIe Slimline SAS 4.0 38-Pin SFF-8654 4i i 4 SATA 7-Pin Right-Angled Cable, etc.
No SAS
ʻO ke kikowaena SCSI Serial Attached (Serial Attached SCSI, SAS) ka ʻenehana SCSI e hiki mai ana. E like me nā mea paʻakikī Serial ATA (SATA) kaulana i kēia manawa, hoʻohana pū ʻo SAS i ka ʻenehana serial e hoʻokō i ka wikiwiki o ka hoʻouna ʻana a hoʻomaikaʻi i ka lewa kūloko ma ka pōkole o nā laina pili. ʻO SAS kahi kikowaena hou loa i hoʻomohala ʻia ma hope o ka interface SCSI like. I nā ʻōnaehana mālama hou, ʻo nā kaula pili e like me MINI SAS 8087 a i 8482 CABLE, MINI SAS 8087 a i 4X SATA 7P wahine kelepona, a me nā mea ʻē aʻe. ʻOi aku ka maikaʻi o ka ʻōnaehana pili ʻākau ʻākau o MINI SAS 8087 a i 4X SATA 7P ʻo ke kaula wahine ʻākau ʻākau ka mea kaulana loa i nā kaiapuni kikowaena me nā wahi liʻiliʻi.
E pili ana iā SATA
Kū ʻo SATA no Serial ATA (Serial Advanced Technology Attachment), i ʻike ʻia ʻo ATA serial. ʻO ia kahi kikoʻī kikowaena paʻakikī paʻakikī i hoʻolauna pū ʻia e Intel, IBM, Dell, APT, Maxtor a me Seagate.
E like me ka mea i hoʻohana nui ʻia ma ka mākeke paʻakikī i kēia manawa, ʻo ka pōmaikaʻi nui loa o ka interface SATA 3.0 ʻo ia kona makua. Hoʻohana nā SSD 2.5-inch maʻamau a me nā HDD i kēia interface. Ma nā ʻōlelo o nā hoʻonā pili, ʻo ka MINI SAS 8087 a i ka 4X SATA 7P Wahine me Sideload e hāʻawi i kahi hopena hoʻokomo ʻaoʻao kūpono, aʻo ka MINI SAS 8087 a i ka 4X SATA 7P ʻo ke kelepona wahine ʻākau kūpono no nā hiʻohiʻona me ka palena palena. ʻO 6 Gbps ka bandwidth transmission theoretical. ʻOiai he ʻokoʻa kona i hoʻohālikelike ʻia me ka bandwidth 10 Gbps a me 32 Gbps o ka interface hou, hiki i nā SSDs 2.5-inch maʻamau ke hoʻokō i nā pono noi i kēlā me kēia lā o ka hapa nui o nā mea hoʻohana, a ua lawa ka wikiwiki heluhelu a kākau ʻana ma kahi o 500 MB/s.
Ke piʻi wikiwiki nei ka nui o ka ʻikepili ma ka honua pūnaewele. Ke hoʻohālikelike ʻia me nā kikowaena o kēia manawa, hiki i ka interface PCI Express ke hāʻawi i ka hoʻouna ʻikepili wikiwiki a me ka latency pōkole, e hoʻomaikaʻi nui i ka pono a me ka loaʻa kālā o nā hui. E ulu nui ana nā pono. I ka manawa like, ʻo nā ʻōnaehana pili hou e like me ka MINI SAS 8087 i ka SAS SFF-8482 ʻElua-ma-Hoʻokahi kelepona a me ka MINI SAS 8087 i Oculink SAS 8611 4I ke koi pū nei i nā palena o ka ʻenehana mālama. ʻOi loa ma nā wahi mālama kiʻekiʻe kiʻekiʻe, nā hoʻolālā hoʻohui ʻokoʻa kūikawā e like me ka MINI SAS 8087 Left-angled i 4X SATA 7P Wahine 90-Degree ua hoʻoponopono i nā pilikia uea.
Ka manawa hoʻouna: ʻAukake-01-2025
