Hauv ob ntu dhau los (, ) peb tau saib cov hauv paus ntsiab lus uas lub tuam txhab kev cai tshiab tau tsim, thiab tham txog kev tsiv teb tsaws ntawm txhua txoj haujlwm. Tam sim no nws yog lub sij hawm los tham txog lub Hoobkas server.
Yav dhau los, peb tsis muaj ib qho kev sib cais server infrastructure: server keyboards tau txuas nrog tib lub hauv paus raws li cov neeg siv khoom faib hloov pauv. Kev tswj kev nkag tau ua tiav siv cov tes hauj lwm virtual (VLANs), VLAN routing tau ua tiav ntawm ib qho - ntawm qhov tseem ceeb (raws li txoj cai ).
qub network infrastructure
Ib txhij nrog lub chaw ua haujlwm tshiab network, peb txiav txim siab los tsim ib chav neeg rau zaub mov tshiab thiab cais lub Hoobkas tshiab rau nws. Nws hloov tawm mus rau me me (peb lub chaw rau khoom), tab sis ua raws li tag nrho cov canons: cais cov tub ntxhais ntawm CE8850 keyboards, tag nrho meshed (s txhav-nplooj) topology, sab saum toj ntawm khib (ToR) CE6870 keyboards, ib khub sib cais. ntawm cov keyboards rau kev cuam tshuam nrog lwm lub network (ciam teb nplooj). Hauv luv, ua tiav mincemeat.
Network ntawm lub Hoobkas tshiab server
Peb txiav txim siab tso tseg neeg rau zaub mov SCS hauv kev pom zoo ntawm kev sib txuas cov servers ncaj qha rau ToR keyboards. Vim li cas? Peb twb muaj ob chav neeg rau zaub mov uas tau tsim siv server SCS, thiab peb pom tau tias qhov no yog:
- tsis yooj yim rau siv (ntau qhov kev sib txuas, koj yuav tsum ua tib zoo hloov kho lub cav cable);
- kim nyob rau hauv cov nqe lus ntawm qhov chaw nyob los ntawm thaj panels;
- yog ib qho teeb meem thaum nws yog ib qho tsim nyog los ua kom cov kev sib txuas ceev ntawm cov servers (piv txwv li, hloov ntawm 1 Gbit / s kev sib txuas ntawm tooj liab mus rau 10 Gbit / s dhau optical).
Thaum tsiv mus rau lub Hoobkas server tshiab, peb sim txav deb ntawm kev sib txuas cov servers ntawm qhov nrawm ntawm 1 Gbit / s thiab txwv peb tus kheej mus rau 10 Gbit interfaces. Yuav luag tag nrho cov qub servers uas tsis tuaj yeem ua qhov no yog virtualized, thiab tus so tau txuas nrog gigabit transceivers rau 10 gigabit ports. Peb tau ua lej thiab txiav txim siab tias nws yuav pheej yig dua li kev txhim kho gigabit keyboards cais rau lawv.
ToR hloov
Tsis tas li ntawd hauv peb chav neeg rau zaub mov tshiab, peb tau teeb tsa cais tawm ntawm pawg tswj hwm (OOM) hloov nrog 24 chaw nres nkoj, ib qho rau ib lub khib. Lub tswv yim no tau ua tau zoo heev, tab sis tsis muaj chaw nres nkoj txaus, lwm zaus peb yuav nruab OOM keyboards nrog 48 chaw nres nkoj.
Peb txuas cov interfaces rau kev tswj chaw taws teeb ntawm cov servers xws li iLO, lossis iBMC hauv Huawei cov lus siv, mus rau OOM network. Yog hais tias tus neeg rau zaub mov tau poob nws lub ntsiab kev twb kev txuas mus rau lub network, ces nws yuav ua tau mus cuag nws ntawm no interface. Tsis tas li ntawd, tswj kev cuam tshuam ntawm ToR keyboards, ntsuas kub, UPS tswj interfaces thiab lwm yam khoom siv zoo sib xws tau txuas nrog OOM keyboards. Lub OOM network nkag tau los ntawm kev sib cais firewall.

Pairing server thiab cov neeg siv network
Nyob rau hauv ib lub Hoobkas kev cai, cais VRFs yog siv rau cov hom phiaj sib txawv - rau kev sib txuas cov neeg siv chaw ua haujlwm, kev soj ntsuam video, cov tshuab multimedia hauv cov chav sib tham, rau kev teeb tsa sawv ntsug thiab thaj chaw demo, thiab lwm yam.
Lwm txheej ntawm VRFs tau tsim nyob rau hauv lub Hoobkas server:
- Txhawm rau txuas cov servers tsis tu ncua uas cov kev pabcuam koom nrog raug xa mus.
- Ib qho VRF cais, nyob rau hauv uas cov servers nrog kev nkag los ntawm Is Taws Nem raug xa mus.
- Ib qho VRF cais rau database servers uas tsuas yog nkag los ntawm lwm cov servers (piv txwv li, daim ntawv thov servers).
- Cais VRF rau peb lub tshuab xa ntawv (MS Exchange + Skype rau Kev Lag Luam).
Yog li peb muaj ib txheej ntawm VRFs ntawm tus neeg siv lub Hoobkas sab thiab ib txheej ntawm VRFs ntawm lub server Hoobkas sab. Ob qhov teeb tsa tau nruab rau ntawm cov koom haum firewall (FW) pawg. MEs txuas nrog ciam teb hloov pauv ( ciam teb nplooj) ntawm ob lub server ntaub thiab cov neeg siv ntaub.

Kev tsiv teb tsaws chaw mus li cas?
Thaum lub sijhawm tsiv teb tsaws, peb tau txuas nrog cov chaw tsim khoom tshiab thiab qub ntawm cov ntaub ntawv txuas, los ntawm cov pob tw ib ntus. Txhawm rau hloov cov servers nyob rau hauv ib qho VLAN tshwj xeeb, peb tsim ib qho chaw txuas ntxiv, uas suav nrog VLAN ntawm lub Hoobkas qub neeg rau zaub mov thiab VXLAN ntawm lub Hoobkas server tshiab.
Lub configuration zoo li no, ob kab kawg yog qhov tseem ceeb:
bridge-domain 22
vxlan vni 600022
evpn
route-distinguisher 10.xxx.xxx.xxx:60022
vpn-target 6xxxx:60022 export-extcommunity
vpn-target 6xxxx:60022 import-extcommunity
interface Eth-Trunk1
mode lacp-static
dfs-group 1 m-lag 1
interface Eth-Trunk1.1022 mode l2
encapsulation dot1q vid 22
bridge-domain 22
Kev tsiv teb tsaws ntawm cov tshuab virtual
Tom qab ntawd, siv VMware vMotion, cov tshuab virtual hauv VLAN no tau tsiv los ntawm cov qub hypervisors (version 5.5) mus rau cov tshiab (version 6.5). Tib lub sijhawm, hardware servers tau virtualized.
Thaum koj sim duaConfigure MTU ua ntej thiab xyuas cov ntawv ntawm cov pob ntawv loj "kawg mus rau qhov kawg".
Hauv cov neeg rau zaub mov qub, peb siv VMware vShield virtual firewall. Txij li thaum VMware tsis txhawb nqa cov cuab yeej no lawm, peb tau hloov los ntawm vShield rau hardware firewalls tib lub sijhawm peb tsiv mus rau qhov tshiab virtual ua liaj ua teb.
Tom qab tsis muaj cov servers sab laug hauv ib qho VLAN ntawm lub network qub, peb hloov routing. Yav dhau los, nws tau ua tiav ntawm cov tub ntxhais qub, tsim los siv Collapsed Backbone thev naus laus zis, thiab hauv lub Hoobkas tshiab server peb siv Anycast Gateway thev naus laus zis.
Hloov routing
Tom qab hloov routing rau ib qho VLAN tshwj xeeb, nws raug txiav tawm ntawm tus choj sau thiab tsis suav nrog lub cev ntawm cov qub thiab tshiab tes hauj lwm, piv txwv li, nws tag nrho tsiv mus rau lub Hoobkas server tshiab. Yog li, peb tsiv teb tsaws txog 20 VLANs.
Yog li peb tsim lub network tshiab, server tshiab thiab ua liaj ua teb virtualization tshiab. Hauv ib qho ntawm cov kab lus hauv qab no peb yuav tham txog yam peb tau ua nrog Wi-nkaus.
