Masiku ano, cholinga chathu sichimangoyang'ana pamzere wazinthu za Huawei popanga ma data center network, komanso momwe tingamangire mayankho apamwamba omaliza potengera iwo. Tiyeni tiyambe ndi zochitika, kupita kuzinthu zenizeni zomwe zimathandizidwa ndi zipangizo, ndikumaliza ndi kufotokoza mwachidule zipangizo zenizeni zomwe zingathe kupanga maziko a malo amakono a deta omwe ali ndi mlingo wapamwamba kwambiri wa machitidwe a intaneti.
Ziribe kanthu momwe zida zapaintaneti zilili zochititsa chidwi, kuthekera kogwiritsa ntchito njira zopangira zomangamanga kumatsimikiziridwa ndi momwe kuphatikizika kwa hardware, mapulogalamu, pafupifupi ndi matekinoloje ena okhudzana nawo kungakhalire. Kuyesera kuti tigwirizane ndi nthawi, timayesetsa kupatsa makasitomala mwayi wamakono komanso wodalirika, womwe nthawi zambiri umakhala patsogolo pa mapulani owopsa a ogulitsa ena.
Mayankho ozikidwa pa Cloud Fabric akuphatikizapo netiweki ya data center, wolamulira wa SDN, komanso zinthu zina zofunika pulojekiti inayake, kuphatikiza kuchokera kwa opanga ena.
Chochitika choyamba komanso chosavuta chimaphatikizapo kugwiritsa ntchito magawo ochepa: maukonde amamangidwa pazida za Huawei ndi zida za chipani chachitatu kuti azisinthiratu njira zoyendetsera ndi kuyang'anira maukonde. Mwachitsanzo, monga Ansible kapena Microsoft Azure.
Chochitika chachiwiri chikuganiza kuti kasitomala akugwiritsa ntchito kale makina a virtualization ndi SDN kumalo osungirako deta, kunena kuti NSX, ndipo akufuna kugwiritsa ntchito zipangizo za Huawei monga hardware VTEP (Vitual Tunnel End Point) mkati mwa njira ya VMware yomwe ilipo. Patsamba la kampaniyi Zida za Huawei zomwe zayesedwa ndipo zitha kugwiritsidwa ntchito ngati VTEP. Pambuyo pake, sizobisika kuti, ziribe kanthu momwe mapulogalamu a VXLAN (Virtual Extensible LAN) amachitira bwino pa zosinthika zenizeni, kukhazikitsidwa kwa hardware kumakhala kothandiza kwambiri pakuchita.
Chochitika chachitatu ndikumanga makina a hosting & computing class omwe amaphatikizapo owongolera, koma alibe nsanja yapamwamba yomwe ingafunike kuphatikizira. Chimodzi mwazinthu zomwe mungachite kuti mugwiritse ntchito nkhaniyi ndi kukhalapo kwa wolamulira wina wa Agile Controller-DCN SDN. Oyang'anira makina angagwiritse ntchito kamangidwe kameneka kuti agwire ntchito zoyang'anira maukonde tsiku ndi tsiku. Mtundu wotukuka kwambiri wa zochitika zachitatu zimatengera kuyanjana kwa Agile Controller-DCN ndi VMware vCenter, olumikizidwa ndi njira inayake yabizinesi, koma popanda dongosolo lapamwamba la oyang'anira.
Chochitika chachinayi ndichofunikira kwambiri - kuphatikiza ndi nsanja yakumtunda kutengera OpenStack kapena FusionSphere virtualization product. Timalembetsa zopempha zambiri zamakina ofanana, omwe OpenStack (CentOS, Red Hat, etc.) ndi otchuka kwambiri. Zonse zimatengera nsanja yanji ya orchestration ndi kasamalidwe kazinthu zamakompyuta zomwe zimagwiritsidwa ntchito mu data center.
Nkhani yachisanu ndi yatsopano. Kuphatikiza pa masiwichi odziwika bwino a hardware, amaphatikizanso chosinthira chogawika cha CloudEngine 1800V (CE1800V), chomwe chimatha kugwiritsidwa ntchito ndi KVM (Kernel-based Virtual Machine). Zomangamangazi zikuphatikiza kuphatikiza Agile Controller-DCN ndi nsanja ya Kubernetes yokhala ndi zida pogwiritsa ntchito pulogalamu yowonjezera ya CNI. Chifukwa chake, Huawei, pamodzi ndi dziko lonse lapansi, akuyenda kuchokera ku host virtualization kupita ku opaleshoni dongosolo virtualization.
Zambiri za containerization
Tidanenapo kale chosinthira cha CE1800V chogwiritsidwa ntchito pogwiritsa ntchito Agile Controller-DCN. Kuphatikiza ndi masiwichi a Huawei, amapanga mtundu wa "kukuta wosakanizidwa". Posachedwapa, zolemba za Huawei zilandila thandizo ku NAT ndi ntchito zofananira.
Kuchepetsa kwa zomangamanga ndikuti CE1800V singagwiritsidwe ntchito mosiyana ndi Agile Controller-DCN. Ziyeneranso kuganiziridwa kuti PoD imodzi ya nsanja ya Kubernetes ikhoza kukhala ndi zotengera zosaposa 4 miliyoni.
Kulumikizana ndi VXLAN network ya data center kumachitika kudzera pa VLAN (Virtual Local Area Network), koma pali njira yomwe CE1800V imagwira ntchito ngati VTEP ndi ndondomeko ya BGP (Border Gateway Protocol). Izi zimalola njira za BGP kuti zisinthidwe ndi msana popanda kufunikira kwa masiwichi osiyana a hardware.
Ma Networks Oyendetsedwa ndi Cholinga: maukonde omwe amasanthula zolinga
Lingaliro la Huawei Intent-Driven Network (IDN). kubwerera ku 2018. Kuyambira nthawi imeneyo, kampaniyo yapitirizabe kugwira ntchito pa maukonde omwe amagwiritsa ntchito teknoloji ya cloud computing, deta yaikulu ndi luntha lochita kupanga kuti afufuze zolinga ndi zolinga za ogwiritsa ntchito.
M'malo mwake, tikukamba za kusuntha kuchoka ku automation kupita ku autonomy. Cholinga cha wogwiritsa ntchito chimabwezedwa ngati malingaliro ochokera kuzinthu zapaintaneti momwe angagwiritsire ntchito cholingachi. Pamtima pa ntchitoyi ndi mphamvu za Agile Controller-DCN zomwe zidzawonjezedwa kuzinthuzo kuti zitsimikizire kukhazikitsidwa kwa malingaliro a IDN.
M'tsogolomu, ndi kukhazikitsidwa kwa IDN, kudzakhala kotheka kuyika mautumiki a pa intaneti mwakamodzi, zomwe zikutanthawuza kuchuluka kwapamwamba kwambiri. Zomangamanga zamtundu wa ntchito zapaintaneti komanso kuthekera kophatikiza ntchitozi zipangitsa kuti woyang'anira azingonena kuti ndi ntchito ziti zomwe ziyenera kupezeka pagawo linalake la intaneti.
Kuti mukwaniritse kuwongolera uku, njira ya ZTP (Zero Touch Provisioning) ndiyofunikira kwambiri. Huawei wachita bwino kwambiri pa izi, chifukwa chake amapereka mwayi wogwiritsa ntchito intaneti kunja kwa bokosi.
Kuyika kwinanso ndi kutumizira kumaphatikizaponso njira yowunikira kulumikizana pakati pa zinthu (kulumikizana kwa netiweki) ndikuwunika kusintha kwa magwiridwe antchito a netiweki kutengera momwe amagwirira ntchito. Gawoli limaphatikizapo kuchita kayeseleledwe musanayambe ntchito yeniyeni.
Chotsatira ndikukonza mautumiki kuti agwirizane ndi zosowa za kasitomala (kupereka chithandizo) ndi kutsimikizira kwawo, kochitidwa ndi zida za Huawei zomangidwa. Ndiye chomwe chatsalira ndikuwunika zotsatira.
Tsopano ndizotheka kudutsa njira yonse yofotokozedwayo pogwiritsa ntchito njira imodzi yokhazikika yokhazikika pa nsanja ya iMaster NCE yomwe ili ndi Agile Controller-DCN ndi eSight network element management system (EMS).
Pakalipano, Agile Controller-DCN akhoza kuyang'ana kupezeka kwa zothandizira ndi kukhalapo kwa maulumikizidwe, komanso mwachidwi (pambuyo pa kuvomereza kwa woyang'anira) kuyankha mavuto pa intaneti. Kuwonjezera ntchito zofunika tsopano kuchitidwa pamanja, koma m'tsogolomu Huawei akufuna kusinthira izi ndi zina, monga kutumiza seva, kasinthidwe ka makina osungira, ndi zina zotero.
Unyolo wautumiki ndi magawo ang'onoang'ono
Agile Controller-DCN imatha kukonza mitu yautumiki (Net Service Headers, kapena NSH) yomwe ili m'mapaketi a VXLAN. Izi ndizothandiza popanga unyolo wautumiki. Mwachitsanzo, mukufuna kutumiza mapaketi amtundu wina panjira yomwe imasiyana ndi yomwe imaperekedwa ndi protocol yokhazikika. Asanachoke pa intaneti, ayenera kudutsa chipangizo chamtundu wina (firewall, etc.). Kuti muchite izi, ndikwanira kukonza unyolo wautumiki womwe uli ndi malamulo ofunikira. Chifukwa cha makina oterowo, ndizotheka, mwachitsanzo, kukonza ndondomeko zachitetezo, koma mbali zina za ntchito yake ndizotheka.
Chithunzichi chikuwonetsa bwino ntchito ya maunyolo a RFC ogwirizana ndi NSH, komanso amapereka mndandanda wa masiwichi a hardware omwe amawathandiza.
Kuthekera kwa maunyolo a Huawei kumathandizidwa ndi magawo ang'onoang'ono, njira yachitetezo pamaneti yomwe imalekanitsa magawo achitetezo kuzinthu zomwe zimalemetsa ntchito. Kupewa kufunikira kokonzekera pamanja ma ACL ambiri kumathandiza kuzungulira botolo la Access Control List (ACL).
Ntchito yanzeru
Kupitilira pa nkhani ya magwiridwe antchito a netiweki, munthu sangalephere kutchula gawo lina la mtundu wa ambulera wa iMaster NCE - FabricInsight intelligent network analyzer. Imapereka mphamvu zambiri zosonkhanitsira ma telemetry ndi zidziwitso zakuyenda kwa data pamaneti. Telemetry imasonkhanitsidwa pogwiritsa ntchito gRPC ndipo imadziunjikira zambiri pamapaketi opatsirana, osungidwa ndi otayika. Chidziwitso chachiwiri chachikulu chimaphatikizidwa pogwiritsa ntchito ERSPAN (Encapsulated Remote Switch Port Analyzer) ndipo imapereka lingaliro lakuyenda kwa data mu data center. Kwenikweni, tikulankhula za kusonkhanitsa mitu ya TCP ndi kuchuluka kwa chidziwitso chomwe chimaperekedwa pagawo lililonse la TCP. Izi zitha kuchitika pogwiritsa ntchito zida zosiyanasiyana za Huawei - mndandanda wawo ukuwonetsedwa pazithunzi.
SNMP ndi NetStream sizikuyiwalikanso, kotero Huawei akugwiritsa ntchito njira zakale komanso zatsopano kuti achoke pa intaneti ngati "bokosi lakuda" kupita ku netiweki yomwe timadziwa zonse.
AI Fabric: Lossless Smart Grid
Mawonekedwe a AI ββFabric omwe amathandizidwa ndi zida zathu adapangidwa kuti asinthe Ethernet kukhala network yogwira ntchito kwambiri, yotsika kwambiri, yopanda paketi yotayika. Izi ndizofunikira kuti mugwiritse ntchito zochitika zoyambira zotumizira mu data center network.
Pachithunzi pamwambapa tikuwona zovuta zomwe zingachitike mukamagwiritsa ntchito netiweki:
- kutayika kwa paketi;
- kusefukira kwa buffer;
- vuto la kutsitsa kwabwino pamaneti mukamagwiritsa ntchito maulalo ofananira.
Zida za Huawei zimagwiritsa ntchito njira zothetsera mavuto onsewa. Mwachitsanzo, pamlingo wa chip, ukadaulo wapamzere womwe ukubwera wayambitsidwa, womwe nthawi yomweyo sulola kutsekereza kolowera (HOL blocking).
Pamlingo wa protocol, pali njira yamphamvu ya ECN - yosinthira kukula kwa buffer, komanso Fast CNP - kutumiza mapaketi a uthenga mwachangu pamavuto pamaneti kupita kugwero.
Ufulu wofanana pamayendedwe ΠΈ Thandizo laukadaulo wa Dynamic Packet Prioritization (DPP) limathandiza, lomwe limaphatikizapo kuyika zidziwitso zazifupi kuchokera ku mitsinje yosiyana kupita pamzere wapadera wofunikira kwambiri. Chifukwa chake, mapaketi afupikitsa amakhala bwino m'malo oyenda nthawi yayitali, olemetsa.
Tiyeni tifotokoze kuti njira zomwe zili pamwambazi zigwire ntchito bwino, ziyenera kuthandizidwa mwachindunji ndi zipangizo.
ntchito zonsezi ntchito imodzi mwa zochitika zitatu ntchito zida Huawei:
- pomanga machitidwe anzeru ochita kupanga potengera ntchito zogawidwa;
- popanga machitidwe osungira deta ogawidwa;
- popanga makina a high performance computing (HPC).
Malingaliro opangidwa mu hardware
Titakambirana za momwe mungagwiritsire ntchito mayankho a Huawei ndikulemba zomwe angakwanitse, tiyeni tipite patsogolo pazida.
CloudEngine 16800 ndi nsanja yomwe imapereka magwiridwe antchito opitilira 400 Gbit/s. Mawonekedwe ake ndi kukhalapo, pamodzi ndi CPU, ya chipangizo chake chotumizira ndi purosesa yanzeru yochita kupanga, yomwe ndi yofunikira kugwiritsa ntchito luso la AI Fabric.
Pulatifomu imapangidwa molingana ndi kamangidwe kapamwamba ka orthogonal yokhala ndi kutsogolo kupita kumbuyo kwa airflow system ndipo imabwera ndi imodzi mwamitundu itatu ya chassis - 4 (10U), 8 (16U) kapena 16 (32U) mipata.
CloudEngine 16800 imatha kugwiritsa ntchito mitundu ingapo yamakhadi amzere. Zina mwa izo ndi zachikhalidwe 10-gigabit ndi 40-, komanso 100-gigabit, kuphatikizapo zatsopano. Makhadi okhala ndi mawonekedwe a 25 ndi 400 Gbit/s amakonzedwa kuti amasulidwe.
Ponena za masiwichi a ToR (Pamwamba pa rack), mitundu yawo yamakono ikuwonetsedwa pamndandanda wanthawi pamwambapa. Chochititsa chidwi kwambiri ndi mitundu yatsopano ya 25-Gigabit, masiwichi a 100-Gigabit okhala ndi 400-Gigabit uplinks, ndi masiwichi apamwamba kwambiri a 100-Gigabit okhala ndi madoko 96.
