chii chinonzi dci.

Kuti zvizadzise zvinodiwa nemabhizinesi ekutsigira masevhisi akawanda uye vashandisi veruzivo rwepamusoro-soro rwenetwork munzvimbo dzakasiyana-siyana, nzvimbo dzedata hadzisisiri "zvitsuwa"; dzinofanira kubatanidzwa kuti dzigovane kana kuchengetedza data uye kuwana load balancing. Sekureva kwemushumo wekutsvagisa kwemusika, musika wepasi rose we data centre unotarisirwa kukura kusvika mabhiriyoni manomwe nemakumi matanhatu nemashanu emadhora ekuAmerica muna 2026, nekukura kwegore negore kwe14% kubva muna 2021 kusvika 2026, uye kubatana kwe data centre kwave tsika.

Chechipiri, chii chinonzi data center interconnection

Data Center Interconnect (DCI) i network solution inoita kuti nzvimbo dze data dzakasiyana dzikwanise kutaurirana. Ine network inochinjika, inoshanda zvakanyanya, yakachengeteka, uye ine nyore kushandisa nekugadzirisa (O&M), ichizadzisa zvinodiwa pakuchinjana data zvakanaka uye kugadzirisa njodzi pakati penzvimbo dze data.

Kubatana kwedata centre kunogona kupatsanurwa zvichienderana nedaro rekutumira data centre uye nzira yekubatanidza network:

Zvichienderana nedaro rekutumira:

1) Kureba kupfupi: mukati me5 km, tambo dzemagetsi dzinoshandiswa kuita kuti nzvimbo dzedata dziri mupaki dzibatane;

2) Kureba kwepakati: mukati memakiromita makumi masere, kazhinji zvinoreva kushandiswa kwemamodule emagetsi mumaguta ari pedyo kana nzvimbo dzepakati nepakati kuti pave nekubatana;

3) Kureba: zviuru zvemakiromita, zvinowanzoreva michina yekutumira optical kuti iwane kubatana kwedata centre kure, senge network yetambo dzemugungwa;

Zvichienderana nenzira yekubatanidza:

1) Network layer three connection: network yepamberi yedata centers dzakasiyana inopinda data center yega yega kuburikidza neIP network, kana primary data center site ikatadza, data rakakopwa kune standby site rinogona kudzoserwa, uye application inogona kutangwazve mukati menguva pfupi yekukanganiswa, zvakakosha kuchengetedza traffic iyi kubva mukurwiswa kwenetwork kwakaipa uye iripo nguva dzose;

2) Kubatana kwe network yeLayer 2: Kuvaka network hombe yeLayer 2 (VLAN) pakati penzvimbo dzakasiyana dzedata kunonyanya kusangana nezvinodiwa zve virtual dynamic migration ye server clusters. Zvinhu zvinotevera zvinofanirwa kufungwa nezvazvo:

Kunonoka kwakaderera: Kubatana kweLayer 2 pakati penzvimbo dzedata kunoshandiswa kuita remote VM scheduling uye cluster remote applications. Kuti izvi zviitike, zvinodiwa zve latency kuti VMS isvike kure uye cluster storage zviitwe.

Kureba kwebandwidth: Chimwe chezvinhu zvakakosha zvekubatanidza nzvimbo dzedata ndechekuona kuti VM inotama munzvimbo dzedata, izvo zvinoisa zvinodiwa zvakanyanya pabandwidth.

Kuwanikwa Kwakawanda: Imwe yenzira dzinoshanda kwazvo dzekuvandudza kuwanikwa ndeyekugadzira ma backup link ekutsigira kuenderera mberi kwebhizinesi

3) Kubatana kwenetiweki yekuchengetedza: Kudzokororwa kwedata pakati penzvimbo huru nenzvimbo yekudzoreredza njodzi kunoitwa kuburikidza netekinoroji yekutumira data (fiber isina optical, DWDM, SDH, nezvimwewo).

Chechitatu, nzira yekuwana kubatana kwedata center

1) Tekinoroji yeMPLS: Chirongwa chekubatanidza chakavakirwa patekinoroji yeMPLS chinoda kuti network yekubatanidza pakati penzvimbo dzedata ive network huru yekushandisa tekinoroji yeMPLS, kuitira kuti kubatana kwakananga kwenzvimbo dzedata kupedzwe zvakananga kuburikidza neVLL neVPLS. MPLS inosanganisira tekinoroji yeLayer 2 VPN uye tekinoroji yeLayer 3 VPN. VPLS protocol ndiyo tekinoroji yeLayer 2 VPN. Zvakanakira zvayo ndezvekuti inogona kuita nyore nyore kuiswa kwenetwork yemetro/wide area, uye inoshandiswa mumaindasitiri mazhinji.

2) Tekinoroji yeIP tunnel: Itekinoroji yekubatanidza mapaketi, iyo inogona kuona kubatana kwakasiyana kwenetwork layer 2 pakati penzvimbo dzakawanda dzedata;

3) Tekinoroji yeVXLAN-DCI tunnel: Ichishandisa tekinoroji yeVXLAN, inogona kuita kuti network dzedata dzakawanda dzibatane neLayer 2 / Layer 3. Zvichienderana nekukura kwetekinoroji uye ruzivo rwebhizinesi, network yeVXLAN inochinjika uye inodzorwa, inoparadzaniswa yakachengeteka, uye inotungamira uye inodzorwa, izvo zvakakodzera kune ramangwana rekubatana kwedata dzakawanda.

4. Magadzirirwo ekugadzirisa data centre uye mazano ezvigadzirwa

Zvinhu zvechirongwa:

1) Kubatana kunochinjika: Kubatana kunochinjika, kunovandudza kuchinjika kwenetwork uye kukura kwayo, kusangana neinternet, kugoverwa kwedata centers, hybrid cloud networking uye kumwe kuwedzera kunochinjika kuri nyore pakati pedata centers dzakawanda;

2) Kuchengetedzwa kwakanaka: Tekinoroji yeDCI inobatsira kugadzirisa mabasa epakati pedata, kugovera zviwanikwa zvemuviri uye zvepaindaneti munzvimbo dzakasiyana siyana kuti iwedzere basa redata, uye kuve nechokwadi chekugoverwa kwakanaka kwetraffic yenetwork pakati pemaseva; Panguva imwe chete, kuburikidza ne dynamic encryption uye strict access control, kuchengetedzwa kwedata rakakosha senge kutengeserana kwemari neruzivo rwemunhu kunovimbiswa kuve nechokwadi chekuti bhizinesi rinoenderera mberi;

4) Kurerutsa mashandiro nekuchengetedza: Gadzirisa masevhisi enetwork zvichienderana nezvinodiwa nebhizinesi, uye zadzisa chinangwa chekurerutsa mashandiro nekuchengetedza kuburikidza nesoftware definition/open network.

HUA6800 - 6.4T DCI WDM transmission platform

Iyo HUA6800 chigadzirwa chitsva cheDCI transmission. Iyo HUA6800 ine hunhu hwehukuru hudiki, mukana wekuwana sevhisi yakakura kwazvo, kuendesa kure kure, manejimendi iri nyore uye iri nyore yekushanda nekugadzirisa, kushanda kwakachengeteka, kuchengetedza simba uye kuderedza kusvibiswa. Inogona kusangana zvinobudirira nezvinodiwa zve daro refu, bandwidth hombe Zvinodiwa zvekubatanidza uye kutumira nzvimbo dzedata remushandisi.

Iyo HUA6800 inoshandisa dhizaini yemodular, iyo isingangotsigire chete kupatsanurwa kwemagetsi emagetsi kuti ideredze mari, asiwo inotsigira manejimendi yakabatanidzwa yemagetsi emagetsi mufuremu imwe chete. Nebasa reSDN, inogadzira dhizaini yenetwork yakangwara uye yakavhurika yevashandisi, inotsigira interface yeYANG model yakavakirwa paNetConf protocol, uye inotsigira nzira dzakasiyana dzekutonga dzakadai seWeb, CLI, uye SNMP, uye inobatsira mashandiro nekugadzirisa. Yakakodzera kune network huru dzakadai senyika backbone networks, provincial backbone networks, uye Metropolitan backbone networks, uye data center interconnection, zvichizadzisa zvinodiwa zvema node ane simba guru pamusoro pe16T. Ndiyo puratifomu yekutumira inodhura zvakanyanya muindasitiri. Imhinduro yekubatanidza kune IDC nevashandi veInternet kuvaka nzvimbo dzedata dzine simba guru.
