I-100GbE: ubunewunewu okanye imfuneko ebalulekileyo?

IEEE P802.3ba, umgangatho wokudlulisa idatha phezu kwe-100 Gigabit Ethernet (100GbE), yaphuhliswa phakathi kwe-2007 kunye ne-2010 [3], kodwa yasasazeka kwi-2018 [5]. Kutheni ngo-2018 kwaye kungekhona ngaphambili? Kwaye kutheni ngokukhawuleza kwimihlambi? Zintlanu izizathu zoku...

I-100GbE: ubunewunewu okanye imfuneko ebalulekileyo?

I-IEEE P802.3ba yaphuhliswa ngokuyinhloko ukuhlangabezana neemfuno zamaziko edatha kunye neemfuno zamanqaku okutshintshana kwe-intanethi ye-intanethi (phakathi kwabaqhubi abazimeleyo); kunye nokuqinisekisa ukusebenza okungaphazanyiswa kweenkonzo zewebhu ezisebenza ngamandla, ezifana neephothali ezinomthamo omkhulu wevidiyo (umzekelo, iYouTube); kunye nekhompyuter esebenza kakhulu. [3] Abasebenzisi be-Intanethi abaqhelekileyo nabo banegalelo ekutshintsheni iimfuno ze-bandwidth: Abantu abaninzi banekhamera yedijithali, kwaye abantu bafuna ukusasaza umxholo abawuthathayo kwi-Intanethi. Oko. Umthamo womxholo ojikelezayo kwi-Intanethi uya usiba mkhulu kwaye ube mkhulu ngokuhamba kwexesha. Zombini kumanqanaba ochwephesha kunye nabathengi. Kuzo zonke ezi meko, xa udlulisa idatha ukusuka kwi-domain enye ukuya kwenye, i-throughput epheleleyo ye-key network nodes sele idlulile izakhono ze-10GbE port. [1] Esi sizathu sokuvela komgangatho omtsha: 100GbE.

Amaziko amakhulu edatha kunye nabanikezeli benkonzo yefu sele besebenzisa ngokusebenzayo i-100GbE, kwaye baceba ukuhamba ngokuthe ngcembe kwi-200GbE kunye ne-400GbE kwiminyaka embalwa. Kwangaxeshanye, sele bejonge kwizantya ezidlula i-terabit. [6] Nangona kukho abanye ababoneleli abakhulu abafudukela kwi-100GbE kuphela kunyaka ophelileyo (umzekelo, iMicrosoft Azure). Amaziko eenkcukacha asebenzisa i-computing ephezulu yokusebenza kwiinkonzo zemali, iiplatifomu zikarhulumente, iiplatifomu zeoli kunye negesi kunye nezixhobo ezisetyenzisiweyo nazo ziqalise ukuhamba kwi-100GbE. [5]

Kumaziko edatha yeshishini, imfuno ye-bandwidth isezantsi kancinci: kutsha nje i-10GbE ibe yimfuneko kunokuba ibe bubunewunewu apha. Nangona kunjalo, njengoko izinga lokusetyenziswa kwetrafikhi likhula ngokukhawuleza ngakumbi nangakumbi, kuyathandabuzeka ukuba i-10GbE iya kuhlala kumaziko edatha yeshishini ubuncinci be-10 okanye iminyaka emi-5. Kunoko, siya kubona utshintsho olukhawulezayo kwi-25GbE kwaye ngokukhawuleza ukuya kwi-100GbE. [6] Ngenxa yokuba, njengoko abahlalutyi be-Intel beqaphela, ukunyanzeliswa kwetrafikhi ngaphakathi kweziko ledatha kwandisa ngonyaka nge-25%. [5]

Abahlalutyi abavela kuDell noHewlett Packard bathi [4] ukuba i-2018 ngunyaka we-100GbE kumaziko edatha. Emuva ngo-Agasti 2018, ukuhanjiswa kwezixhobo ze-100GbE kwakuphindwe kabini kunokuhanjiswa kuwo wonke unyaka we-2017. Kwaye isantya sokuthunyelwa siyaqhubeka nokukhawuleza njengoko amaziko edatha eqala ukuhamba kude ne-40GbE kwimihlambi. Kulindeleke ukuba nge-2022, i-19,4 yezigidi ze-100GbE izibuko ziya kuthunyelwa ngonyaka (kwi-2017, ngokuthelekisa, eli nani laliyi-4,6 yezigidi). [4] Ngokumalunga neendleko, kwi-2017 i-100 yezigidigidi zeedola zachithwa kwii-ports ze-7GbE, kwaye kwi-2020, ngokwezibikezelo, malunga ne-20 yeebhiliyoni zeedola ziya kuchithwa (jonga umfanekiso 1).

Kutheni ngoku? I-100GbE ayisiyiyo itekhnoloji entsha ncam, kutheni ke kukho i-hype eninzi malunga nayo ngoku?

1) Ngenxa yokuba le teknoloji ikhulile kwaye iyabiza. Kwakuyi-2018 ukuba sawela umgca xa sisebenzisa iiplatifomu ezineechweba ze-100-Gigabit kwiziko ledatha yaba yindleko esebenzayo kunokuba "i-stacking" iiplatifomu ezininzi ze-10-Gigabit. Umzekelo: I-Ciena 5170 (jonga i-Figure 2) yiplatifomu edibeneyo enika i-aggregate throughput ye-800GbE (4x100GbE, 40x10GbE). Ukuba izibuko ezininzi ze-10-Gigabit zifunekayo ukubonelela nge-throughput efunekayo, ngoko iindleko ze-hardware ezongezelelweyo, indawo eyongezelelweyo, ukusetyenziswa kwamandla angaphezulu, ukugcinwa okuqhubekayo, iinxalenye ezongezelelweyo kunye neenkqubo zokupholisa ezongezelelweyo zongeza kwixabiso elihle elicocekileyo. [1] Ngokomzekelo, iingcali zeHewlett Packard, zihlalutya iingenelo ezinokubakho zokuhamba ukusuka kwi-10GbE ukuya kwi-100GbE, zafika kumanani alandelayo: ukusebenza okuphezulu (56%), iindleko eziphantsi (27%), ukusetyenziswa kwamandla aphantsi (31%), ukwenza lula uqhagamshelo lweentambo (ngama-38%). [5]

I-2) I-Juniper kunye neCisco ekugqibeleni baye badala i-ASIC yabo kwi-100GbE yokutshintsha. [5] Obubungqina obucacileyo bokuba iteknoloji ye-100GbE ikhulile ngokwenene. Inyani kukuba kuyindleko-esebenzayo ukwenza iitshiphusi ze-ASIC kuphela xa, okokuqala, ingqiqo ephunyeziweyo kubo ayifuni utshintsho kwikamva elibonakalayo, kwaye okwesibini, xa inani elikhulu lee-chips ezifanayo zenziwa. IJuniper kunye neCisco abayi kuvelisa ezi ASIC ngaphandle kokuzithemba ekuvuthweni kwe-100GbE.

I-3) Ngenxa yokuba i-Broadcom, i-Cavium, kunye ne-Mellanox Technologie sele iqalile ukukhupha iiprosesa ngenkxaso ye-100GbE, kwaye ezi ziprosesa sele zisetyenziselwa ukutshintshwa kwabavelisi abafana noDell, Hewlett Packard, Huawei Technologies, Lenovo Group, njl. [5]

I-4) Ngenxa yokuba iiseva ezigcinwe kwii-racks ze-server zixhotyiswa ngakumbi ngee-adapter zenethiwekhi ze-Intel zamva nje (jonga umfanekiso we-3), kunye namachweba amabini angama-25-Gigabit, kwaye ngamanye amaxesha adityaniswe neeadaptha zenethiwekhi ezinezibuko ezimbini ze-40-Gigabit (XXV710 kunye ne-XL710) . {Umfanekiso 3. Ii-Intel NIC zamva nje: XXV710 kunye neXL710}

5) Ngenxa yokuba izixhobo ze-100GbE zibuyela ngasemva zihambelana, okwenza kube lula ukuthunyelwa: ungasebenzisa kwakhona iintambo ezisele zihanjiswe (vele udibanise i-transceiver entsha kubo).

Ukongezelela, ukufumaneka kwe-100GbE kusilungiselela ubuchwepheshe obutsha obufana ne "NVMe phezu kweFabrics" (umzekelo, i-Samsung Evo Pro 256 GB NVMe PCIe SSD; jonga umfanekiso we-4) [8, 10], "Inethiwekhi yendawo yokugcina" (SAN) ) / "I-Software Defined Storage" (jonga umfanekiso we-5) [7], i-RDMA [11], leyo ngaphandle kwe-100GbE ayikwazanga ukuqonda amandla abo apheleleyo.

Ekugqibeleni, njengomzekelo ongaqhelekanga wemfuno esebenzayo yokusetyenziswa kwe-100GbE kunye nobuchwepheshe obunxulumene nesantya esiphezulu, sinokukhankanya ifu lesayensi yeYunivesithi yaseCambridge (jonga umfanekiso we-6), eyakhiwe ngesiseko se-100GbE (Spectrum). I-SN2700 Ethernet switchs) - ngokulandelelana, phakathi kwezinye izinto, qinisekisa ukusebenza ngokufanelekileyo kwe-NexentaEdge SDS ehambisa i-disk storage, engakwazi ukulayisha ngokulula inethiwekhi ye-10 / 40GbE. [2] Amafu enzululwazi anjalo asebenza ngokuphezulu asetyenziselwa ukusombulula iingxaki ezininzi ezahlukeneyo zesayensi [9, 12]. Ngokomzekelo, izazinzulu zonyango zisebenzisa amafu anjalo ukucacisa i-genome yomntu, kunye nemijelo ye-100GbE isetyenziselwa ukudlulisa ulwazi phakathi kwamaqela ophando eyunivesithi.
