100GbE: umbozha kana zvakakosha zvinodiwa?

IEEE P802.3ba, chiyero chekufambisa data pamusoro pe100 Gigabit Ethernet (100GbE), yakagadziridzwa pakati pa2007 na2010 [3], asi yakapararira mu2018 [5]. Sei muna 2018 uye kwete kare? Uye sei pakarepo mumapoka? Pane zvikonzero zvishanu zveizvi ...

IEEE P802.3ba yakagadziridzwa kunyanya kusangana nezvinodiwa zve data centers uye zvinodiwa zveInternet traffic exchange points (pakati pevashandi vakazvimiririra); pamwe nekuona kusakanganisika kushanda kwezviwanikwa-zvakawanda zvewebhu masevhisi, senge maportals ane huwandu hukuru hwemavhidhiyo emukati (semuenzaniso, YouTube); uye neyepamusoro-inoshanda komputa. [3] Vashandisi veIndaneti vakajairwa vari kubatsirawo pakuchinja bandwidth zvinodiwa: Vanhu vazhinji vane makamera edhijitari, uye vanhu vanoda kufambisa zvinhu zvavanotora paInternet. Izvozvo. Huwandu hwezvinhu zviri kutenderera paInternet huri kuramba huchikura nekufamba kwenguva. Zvese pahunyanzvi uye nhanho dzevatengi. Muzviitiko zvese izvi, kana uchiendesa data kubva kune imwe dura kuenda kune imwe, iyo yakazara yekubuda kwekiyi network node yakareba kupfuura kugona kwe10GbE ports. [1] Ichi ndicho chikonzero chekubuda kweyero nyowani: 100GbE.

Nzvimbo huru dzedata uye vanopa masevhisi emakore vave kutoshanda nesimba kushandisa 100GbE, uye vanoronga kutamira ku200GbE uye 400GbE mumakore mashoma. Panguva imwecheteyo, ivo vari kutotarisa kumhanya kunodarika terabit. [6] Kunyangwe paine vamwe vatengesi vakuru vari kuenda ku100GbE chete gore rapfuura (semuenzaniso, Microsoft Azure). Nzvimbo dzeData dzinomhanya dzepamusoro-kushanda komputa yemasevhisi emari, mapuratifomu ehurumende, mapuratifomu emafuta uye gasi uye zvishandiso zvatangawo kuenda ku100GbE. [5]

Munzvimbo dzebhizinesi redata, kudiwa kwebandwidth kwakati kwakadzikira: nguva pfupi yadarika ine 10GbE yave chinhu chinodiwa kwete cheumbozha pano. Nekudaro, sezvo mwero wekushandiswa kwetraffic uchikura nekukurumidza zvakanyanya, hazvina chokwadi kuti 10GbE ichagara mumabhizinesi data centers kweinenge 10 kana kunyange 5 makore. Pane kudaro, tichaona kukurumidza kufamba kuenda ku25GbE uye yakatokurumidza kufamba kuenda ku100GbE. [6] Nekuti, sevanoongorora Intel, kusimba kwetraffic mukati me data data kunowedzera gore negore ne25%. [5]

Vanoongorora kubva kuDell naHewlett Packard vanoti [4] kuti 2018 igore re100GbE renzvimbo dzedata. Kudzoka muna Nyamavhuvhu 2018, kuburitswa kwe100GbE michina yaive yakakwira zvakapetwa kaviri sekutakura kwegore rose ra2017. Uye kumhanya kwekutakura kuri kuramba kuchikwira sezvo nzvimbo dzedata dzichitanga kubva ku40GbE mumapoka. Zvinotarisirwa kuti panosvika 2022, 19,4 miriyoni 100GbE ports ichaendeswa gore negore (muna 2017, kuenzanisa, nhamba iyi yaiva mamiriyoni 4,6). [4] Kana iri mari, mu2017 $ 100 bhiriyoni yakashandiswa pazviteshi zve7GbE, uye mu2020, maererano nekufanotaura, inenge madhora mabhiriyoni makumi maviri emadhora achashandiswa (ona Fig. 20). [1]

Sei zvino? 100GbE haisi iyo tekinoroji nyowani, saka nei paine hype yakawanda yakaitenderedza izvozvi?

1) Nekuti tekinoroji iyi yakura uye yakachipa. Makanga muri muna 2018 kuti takayambuka mutsetse tichishandisa mapuratifomu ane 100-Gigabit ports munzvimbo yedata yakava inodhura-inoshanda pane "stacking" akati wandei 10-Gigabit mapuratifomu. Muenzaniso: Ciena 5170 (ona Figure 2) ipuratifomu yakabatana inopa aggregate throughput ye800GbE (4x100GbE, 40x10GbE). Kana akawanda 10-Gigabit ports achidiwa kuti ape iyo inodiwa yekufambisa, ipapo mari yekuwedzera hardware, imwe nzvimbo, yakawandisa simba rekushandisa, inoenderera mberi kugadzirisa, mamwe maspare parts uye mamwe ekutonhodza masisitimu anowedzera kusvika kumari yakarongeka. [1] Semuyenzaniso, nyanzvi dzeHewlett Packard, dzichiongorora zvingangobatsira zvekufamba kubva ku10GbE kusvika ku100GbE, dzakauya kune nhamba dzinotevera: kushanda kwepamusoro (56%), kuderera kwemari (27%), kushandiswa kwesimba shoma (31%), kurerutsa tambo dzekubatanidza (ne38%). [5]

2) Juniper neCisco vakapedzisira vagadzira yavo ASICs ye100GbE switch. [5] Icho chiri chokwadi chakajeka chechokwadi chekuti 100GbE tekinoroji yakakura zvechokwadi. Icho chokwadi ndechekuti inodhura-inoshanda kugadzira machipisi eASIC chete kana, chekutanga, pfungwa dzakaitwa pavari dzisingadi shanduko mune ramangwana rinoonekwa, uye chechipiri, kana nhamba huru yemachipisi akafanana anogadzirwa. Juniper naCisco vaisazogadzira aya maASIC pasina kuve nechivimbo mukukura kwe100GbE.

3) Nekuti Broadcom, Cavium, uye Mellanox Technologie vatanga kuburitsa ma processors nerutsigiro rwe100GbE, uye ma processor aya atoshandiswa mukuchinjika kubva kune vanogadzira vakaita saDell, Hewlett Packard, Huawei Technologies, Lenovo Group, nezvimwe. [5]

4) Nekuti maseva akaiswa muserver racks ari kuwedzera kuve akashongedzerwa neazvino Intel network adapters (ona Mufananidzo 3), ine maviri 25-Gigabit ports, uye dzimwe nguva kunyange akachinja network adapter ane maviri 40-Gigabit ports (XXV710 uye XL710) . {Mufananidzo 3. Mazuvano Intel NICs: XXV710 uye XL710}

5) Nekuti 100GbE midziyo inodzokera kumashure inoenderana, iyo inorerutsa kutumira: unogona kushandisa zvakare tambo dzakafambiswa kare (ingobatanidza transceiver nyowani kwavari).

Mukuwedzera, kuwanikwa kwe100GbE kunotigadzirira michina mitsva yakadai se "NVMe over Fabrics" (somuenzaniso, Samsung Evo Pro 256 GB NVMe PCIe SSD; ona Fig. 4) [8, 10], "Storage Area Network" (SAN) ) / "Software Defined Storage" (ona Fig. 5) [7], RDMA [11], iyo isina 100GbE yaisagona kuona kukwanisa kwavo kuzere.

Pakupedzisira, semuenzaniso unoshamisa wekudiwa kunoshanda kwekushandiswa kwe100GbE uye yakabatana nepamusoro-soro tekinoroji, tinogona kutaura nezvegore resainzi reYunivhesiti yeCambridge (ona Fig. 6), iyo yakavakwa pahwaro hwe100GbE (Spectrum). SN2700 Ethernet switches) - kuitira, pakati pezvimwe zvinhu, chengetedza kushanda kwakanaka kweNexentaEdge SDS yakagoverwa dhisiki yekuchengetedza, iyo inogona kuremedza nyore nyore 10/40GbE network. [2] Makore akadaro esainzi anoshanda zvakanyanya anoiswa kuti agadzirise zvakasiyana-siyana zvakashandiswa zvesainzi matambudziko [9, 12]. Semuenzaniso, masayendisiti ezvokurapa anoshandisa makore akadaro kutsanangura genome yemunhu, uye 100GbE nzira dzinoshandiswa kuendesa ruzivo pakati pemapoka ekuyunivhesiti.
