ʻO IEEE P802.3ba, kahi maʻamau no ka hoʻouna ʻana i ka ʻikepili ma luna o 100 Gigabit Ethernet (100GbE), i kūkulu ʻia ma waena o 2007 a me 2010 [3], akā ua laha wale ʻia ma 2018 [5]. No ke aha ma 2018 a ʻaʻole ma mua? A no ke aha i hui pū ai? Aia ma kahi o ʻelima mau kumu o kēia...
Ua hoʻomohala nui ʻia ʻo IEEE P802.3ba no ka hoʻokō ʻana i nā pono o nā kikowaena data a me nā pono o nā wahi hoʻololi kaʻa pūnaewele (ma waena o nā mea hana kūʻokoʻa); a me ka hōʻoia ʻana i ka hana pau ʻole o nā lawelawe pūnaewele waiwai, e like me nā puka puka me ka nui o nā wikiō wikiō (e like me YouTube); a no ka helu helu hana kiʻekiʻe. [3] Ke hāʻawi pū nei nā mea hoʻohana pūnaewele maʻamau i ka hoʻololi ʻana i nā koi bandwidth: Nui nā poʻe i loaʻa nā kiʻi kiʻi kiʻi kiʻi, a makemake ka poʻe e kahe i ka ʻike a lākou e hopu ai ma ka Pūnaewele. ʻO kēlā. ʻO ka nui o nā mea e hoʻolaha ana ma ka Pūnaewele ke ulu a nui aʻe i ka wā. Ma nā pae ʻoihana a me nā mea kūʻai aku. I kēia mau hihia a pau, i ka wā e hoʻololi ai i ka ʻikepili mai kahi kikowaena i kekahi, ua lōʻihi ka nui o ka throughput o nā nodes pūnaewele nui ma mua o ka hiki o nā awa 10GbE. [1] ʻO kēia ke kumu o ka puka ʻana o kahi maʻamau hou: 100GbE.
Ke hoʻohana nei nā kikowaena ʻikepili nui a me nā mea lawelawe kapuaʻi i ka 100GbE, a e hoʻolālā e neʻe mālie i 200GbE a me 400GbE i nā makahiki ʻelua. I ka manawa like, ke nānā nei lākou i nā wikiwiki ma mua o terabit. [6] ʻOiai aia kekahi mau mea hoʻolako nui e neʻe ana i ka 100GbE wale nō i ka makahiki i hala (no ka laʻana, Microsoft Azure). Ua hoʻomaka hoʻi nā kikowaena ʻikepili e holo ana i ka helu helu hana kiʻekiʻe no nā lawelawe kālā, nā kahua aupuni, nā ʻaila a me nā ʻea a me nā pono hana e neʻe i 100GbE. [5]
Ma nā kikowaena ʻikepili ʻoihana, ʻoi aku ka haʻahaʻa o ka noi no ka bandwidth: i kēia manawa ua lilo ʻo 10GbE i mea e pono ai ma mua o kahi waiwai ma aneʻi. Eia naʻe, i ka ulu ʻana o ka nui o ka hoʻohana ʻana i nā kaʻa a me ka wikiwiki, ke kānalua nei ka noho ʻana o 10GbE i nā kikowaena ʻikepili ʻoihana no ka liʻiliʻi o 10 a i ʻole 5 mau makahiki. Akā, e ʻike mākou i kahi neʻe wikiwiki i 25GbE a ʻoi aku ka wikiwiki o ka neʻe ʻana i 100GbE. [6] No ka mea, e like me ka ʻike ʻana o nā mea loiloi Intel, piʻi ka nui o ke kaʻa i loko o ka kikowaena data i kēlā me kēia makahiki e 25%. [5]
ʻO nā mea loiloi mai Dell a me Hewlett Packard mokuʻāina [4] ʻo 2018 ka makahiki o 100GbE no nā kikowaena data. Ma hope o ʻAukake 2018, ʻoi aku ka nui o ka lawe ʻana i nā mea hana 100GbE ma mua o ka hoʻouna ʻana no ka makahiki 2017 holoʻokoʻa. A ke hoʻomau nei ka wikiwiki o ka hoʻouna ʻana i ka hoʻomaka ʻana o nā kikowaena ʻikepili e neʻe aku mai 40GbE i ka nui. Manaʻo ʻia e 2022, 19,4 miliona mau awa 100GbE e hoʻouna ʻia i kēlā me kēia makahiki (ma 2017, no ka hoʻohālikelike ʻana, ʻo 4,6 miliona kēia helu). [4] No nā kumukūʻai, ma 2017 $ 100 biliona i hoʻohana ʻia ma nā awa 7GbE, a ma 2020, e like me nā wānana, e hoʻopau ʻia kahi $ 20 biliona (e nānā i ka Fig. 1). [1]
Kiʻi 1. Nā helu a me nā wānana o ka noi no nā lako pūnaewele
No ke aha i kēia manawa? ʻAʻole ʻo 100GbE kahi ʻenehana hou, no laila no ke aha ka nui o ka hype a puni ia i kēia manawa?
1) No ka mea, ua oʻo kēia ʻenehana a lilo i mea maʻalahi. Ma 2018 mākou i hele ai i ka laina i ka wā e hoʻohana ai i nā paepae me nā awa 100-Gigabit i ke kikowaena data i lilo i ʻoi aku ka maikaʻi ma mua o ka "hoʻopaʻa ʻana" i kekahi mau kahua 10-Gigabit. Laʻana: ʻO Ciena 5170 (e ʻike i ke Kiʻi 2) he paepae paʻa e hāʻawi ana i ka hoʻonui ʻana o 800GbE (4x100GbE, 40x10GbE). Inā makemake ʻia nā awa he 10-Gigabit e hāʻawi i ka throughput e pono ai, a laila hoʻohui ʻia nā kumukūʻai o nā lako ʻē aʻe, nā wahi ʻē aʻe, ka hoʻohana ʻana i ka mana, ka mālama mau ʻana, nā ʻāpana ʻokoʻa a me nā ʻōnaehana hoʻomaha hou e hoʻohui i kahi huina nani. [1] No ka laʻana, ʻo nā loea Hewlett Packard, e nānā ana i nā pono kūpono o ka neʻe ʻana mai 10GbE a i 100GbE, ua hele mai i kēia mau helu: ʻoi aku ka hana kiʻekiʻe (56%), haʻahaʻa haʻahaʻa koina (27%), haʻahaʻa haʻahaʻa hoʻohana mana (31%), hoʻopili uwea maʻalahi (e 38%). [5]
Kiʻi 2. Ciena 5170: laʻana paepae me 100 Gigabit awa
2) Ua hana hope ʻo Juniper a me Cisco i kā lākou mau ASIC no nā hoʻololi 100GbE. [5] ʻO ia ka hōʻoia eloquent o ka ʻoiaʻiʻo ʻo ka ʻenehana 100GbE he makua maoli. ʻO ka mea ʻoiaʻiʻo, ʻoi aku ka maikaʻi o ka hana ʻana i nā chips ASIC wale nō inā, ʻo ka mea mua, ʻaʻole pono ka loiloi i hoʻokō ʻia ma luna o lākou i nā loli i ka wā e hiki mai ana, a ʻo ka lua, i ka wā i hana ʻia ai ka nui o nā pahu like. ʻAʻole e hana ʻo Juniper a me Cisco i kēia mau ASIC me ka ʻole o ka hilinaʻi i ke oʻo ʻana o 100GbE.
3) No ka mea, ua hoʻomaka ʻo Broadcom, Cavium, a me Mellanox Technologie e hoʻoulu i nā mea hana me ke kākoʻo 100GbE, a ua hoʻohana mua ʻia kēia mau mea hana i nā hoʻololi mai nā mea hana e like me Dell, Hewlett Packard, Huawei Technologies, Lenovo Group, etc. [5]
4) No ka mea, ua hoʻolako nui ʻia nā kikowaena i loko o nā kikowaena kikowaena me nā mea hoʻopili pūnaewele Intel hou loa (e ʻike i ke Kiʻi 3), me ʻelua mau awa 25-Gigabit, a i kekahi manawa ua hoʻohui pū ʻia nā mea hoʻopili pūnaewele me ʻelua mau awa 40-Gigabit (XXV710 a me XL710). {Figure 3. Nā Intel NIC hou loa: XXV710 a me XL710}
5) No ka mea, hiki i ka mea hana 100GbE ke hoʻopaʻa i hope, e maʻalahi ai ka hoʻolaha ʻana: hiki iā ʻoe ke hoʻohana hou i nā uwea i hele mua ʻia (e hoʻopili wale i kahi transceiver hou iā lākou).
Eia kekahi, hoʻomākaukau ka loaʻa o 100GbE iā mākou no nā ʻenehana hou e like me "NVMe over Fabrics" (no ka laʻana, Samsung Evo Pro 256 GB NVMe PCIe SSD; e ʻike i ka Fig. 4) [8, 10], "Storage Area Network" (SAN ) / "Software Defined Storage" (e nānā i ka Fig. 5) [7], RDMA [11], me ka ʻole o 100GbE ʻaʻole hiki ke hoʻomaopopo i ko lākou pono piha.

Kiʻi 5. "Storage Area Network" (SAN) / "Software Defined Storage"
ʻO ka mea hope loa, ma ke ʻano he hiʻohiʻona exotic o ka noi kūpono no ka hoʻohana ʻana i ka 100GbE a me nā ʻenehana kiʻekiʻe e pili ana, hiki iā mākou ke kuhikuhi i ke ao ʻepekema o ke Kulanui o Cambridge (e nānā i ka Fig. 6), i kūkulu ʻia ma ke kumu o 100GbE (Spectrum). SN2700 Ethernet hoʻololi) - ma ke ʻano, ma waena o nā mea ʻē aʻe, e hōʻoia i ka hana maikaʻi ʻana o NexentaEdge SDS puʻupuʻu disk storage, hiki ke maʻalahi i ka hoʻouka ʻana i kahi pūnaewele 10/40GbE. [2] Hoʻohana ʻia kēlā mau ao ʻepekema hana kiʻekiʻe e hoʻoponopono i nā pilikia ʻepekema i hoʻohana ʻia [9, 12]. No ka laʻana, hoʻohana ka poʻe ʻepekema lapaʻau i kēlā mau ao e wehewehe i ka genome kanaka, a hoʻohana ʻia nā kaha 100GbE e hoʻololi i ka ʻike ma waena o nā hui noiʻi kulanui.
