Ndi kukula kwa zomangamanga , tinkafunika kutumiza zosintha zatsopano za 25 Gbps pamlingo wofikira pa seva. Tikuwuzani momwe tidasankhira Huawei 6865, kumasula zida ndikukuwuzani zomwe tidayamba kugwiritsa ntchito.
Kupanga zofunika
M'mbuyomu, takhala ndi zokumana nazo zabwino ndi Cisco ndi Huawei. Timagwiritsa ntchito Cisco panjira, ndi Huawei posintha. Pakali pano tikugwiritsa ntchito CloudEngine 6810. Chilichonse chili bwino - zipangizo zimagwira ntchito bwino komanso zodziwikiratu, ndipo mtengo wa kukhazikitsa ndi wotsika mtengo kusiyana ndi analogues kuchokera ku Cisco ndi ogulitsa ena. Mwa njira, pafupifupi 6800 mndandanda .
Ndizomveka kupitiriza kugwiritsa ntchito kuphatikiza uku, koma tikufuna njira yamphamvu kwambiri - kukulitsa maukonde ku 25 Gbit / s pa doko, m'malo mwa 10 Gbit / s yamakono.
Zofunikira zathu zina: uplinks - 40/100, osatsekereza kusintha, matrix apamwamba kwambiri, L3 thandizo, stacking. Zomwe tikufuna m'tsogolomu: thandizo la Leaf-Spine, VXLAN, BGP EVPN. Ndipo, ndithudi, mtengo - mtengo wa ntchito umakhudza mtengo wotsiriza wa mtambo kwa makasitomala athu, choncho ndikofunika kusankha chisankho ndi chiΕ΅erengero chabwino cha mtengo wamtengo wapatali.
Kusankha ndi kutumiza
Posankha, tinakhazikika pa opanga atatu - Dell, Cisco ndi Huawei. Monga talembera pamwambapa, timayesetsa kugwiritsa ntchito anzathu omwe adayesedwa nthawi yayitali, ndipo tili ndi lingaliro labwino la momwe zida zawo zimakhalira komanso momwe ntchitoyo imagwirira ntchito.
Mitundu yotsatirayi idakwaniritsa zomwe tikufuna:
Koma titangoyerekeza pangβono, tinakhazikika pa njira yoyamba. Zinthu zingapo zidakhudza izi: mtengo wowoneka bwino, kutsata kwathunthu zomwe tikufuna komanso magwiridwe antchito osasokoneza amitundu yam'mbuyomu kuchokera kwa wopanga uyu. Zasankhidwa, titha kuyitanitsa gulu la CE 6865 mosamala.
Tinayerekeza, kuyitanitsa ndipo potsiriza tinalandira zosintha zatsopano
Ndipo kotero phwandolo linafika pa data center. Timatsegula ndipo poyang'ana koyamba timawona kuti palibe kusiyana kowonekera kuchokera ku 6810. Chinthu chokhacho chodziwika ndi chakuti mtundu watsopanowu uli ndi chiwerengero chachikulu cha uplinks ndi madoko amtundu wina (SFP28 ndi QSFP28, m'malo mwa SFP + ndi QSFP +, motsatira), zomwe zidzatithandiza kuwonjezera liwiro la intaneti mpaka 25 Gbit / s m'malo mwa 10 Gbit / s kwa SFP28 mpaka 100 Gbit / s m'malo mwa 40 Gbit / s kwa QSFP28.
Kuyika ma switch mu rack yatsopano
Zochitika zogwirira ntchito
Chotsatira chake, palibe mavuto omwe adadziwika pa mwezi wa ntchito zosinthika zatsopano, zipangizo zimagwira ntchito mosalekeza. Komabe, posankha Huawei, muyenera kukhala okonzeka chifukwa chakuti ena owerenga adzafunika nthawi kuzolowera mawonekedwe awo opaleshoni dongosolo.
Malinga ndi momwe timamvera, mawonekedwe a Huawei VRP ali penapake pakati pa IOS ndi Comware. Ndipo apa zidzakhala zosavuta ngati mutagwira ntchito ndi Comware kuchokera ku HPE, koma kwa ogwiritsa ntchito Cisco, m'malo mwake, zidzakhala zovuta kwambiri. Zoonadi, izi sizowopsa, koma ndizofunikanso kuziganizira posankha zida.
Zochitika ndi Huawei kusintha kwa zaka zoposa 4 zimasiya mosakayikira pakusankha. CloudEngine 6885 siyotsika poyerekeza ndi mayankho a opikisana nawo mwaukadaulo, ndiyosangalatsa ndi mtengo wake ndipo imatilola kupereka mayankho odalirika amtambo kwa makasitomala athu.
Ndife okondwa kuyankha mafunso anu okhudza hardware ndi mitambo mu ndemanga. Tikuwuzaninso zambiri zakukhazikitsa CloudEngine 6885 m'modzi mwazolemba zotsatirazi - kuti musaphonye.
