Mau oyamba
Kwa zaka zambiri za ntchito yanga m'munda wa IT komanso makamaka mu malonda a IT, ndawona ntchito zambiri zoyendetsa ndege, koma ambiri a iwo anatha popanda kanthu ndipo adatenga nthawi yochuluka.
Panthawi imodzimodziyo, ngati tikukamba za kuyesa mayankho a hardware, monga machitidwe osungira, pa dongosolo lililonse lachiwonetsero nthawi zambiri pamakhala mndandanda wodikira pafupifupi chaka chimodzi pasadakhale. Ndipo mayeso aliwonse pandandanda amatha kubweretsa kugulitsa kapena, m'malo mwake, kuwononga kugulitsa. Palibe chifukwa choganizira momwe kuyesa sikukhudzira malonda, popeza kuyesanso sikumveka - ndikuwononga nthawi komanso kuwononga nthawi kwadongosolo la demo.
Ndiye, mungatani kuti muchite zonse mwanzeru ndikupangitsa zonse kuchitika?
Kukonzekera
Zolinga za woyendetsa ndege
Kodi woyendetsa ndege amayambira kuti? Osati ndi zida zolumikizira ku rack, ayi. Ntchito iliyonse pazida isanayambe, mapepala amalembedwa. Ndipo timayamba ndi kufotokoza zolinga za woyendetsa ndegeyo.
Cholinga cha woyendetsa ndege ndikuchotsa zotsutsa kuchokera kwa kasitomala womaliza. Palibe zotsutsa - palibe woyendetsa wofunikira. Inde Inde ndendende.
Koma ndi magulu ati akuluakulu a zotsutsa omwe tingawone?
* Timakayikira kudalirika
*Tikukayika pakuchita bwino
* Timakayikira scalability
*Tikukayika za kugwirizana komanso kuthekera kogwira ntchito ndi makina athu
* Sitimakhulupirira zithunzi zanu ndipo tikufuna kuwonetsetsa kuti makina anu amatha kuchita zonsezi
* Zonsezi zidzakhala zovuta kwambiri, mainjiniya athu ali otanganidwa kale ndipo zidzakhala zovuta kwa iwo
Ponseponse, pamapeto pake timapeza mitundu itatu yayikulu yoyeserera yoyendetsa ndege ndipo, monga mwapadera woyendetsa, umboni wa lingaliro (PoC - umboni wa lingaliro):
* Kuyesa kwa katundu (+ scalability)
* Kuyesa kogwira ntchito
* Kuyesa kulekerera zolakwika
Pazochitika zinazake, malingana ndi kukayikira kwa kasitomala wina, woyendetsa ndege angaphatikize zolinga zosiyana, kapena, m'malo mwake, mmodzi wa iwo angakhalepo.
Woyendetsa ndegeyo akuyamba ndi chikalata chofotokoza m'Chirasha chomveka chifukwa chake kuyesaku kukuchitika. Zimaphatikizaponso ndondomeko yovomerezeka yoyezera zomwe zimapangitsa kuti zikhale zotheka kunena mosabisa ngati woyendetsa ndegeyo adadutsa bwino kapena zomwe sizinapitirire. Njira zoyezera zitha kukhala manambala (monga latency mu ms, IOPS) kapena binary (inde/ayi). Ngati woyendetsa wanu ali ndi mtengo wosayezeka ngati muyeso, palibe chifukwa mu woyendetsa ndegeyo, ndi chida chachinyengo chabe.
Zida
Woyendetsa akhoza kuchitidwa pazida zowonetsera za wogulitsa / wogawa / mnzanu kapena pazida zamakasitomala. Kunena zowona, kusiyana kuli kochepa, njira yofananira ndi yofanana.
Funso lalikulu lokhudza zida za woyendetsa ndege asanayambike ndikuti ngati zida zonse zilipo (kuphatikiza masiwichi, zingwe za data, zingwe zamagetsi)? Kodi zida zakonzeka kuyesa (mawonekedwe olondola a firmware, zonse zimathandizidwa, magetsi onse ndi obiriwira)?
Kutsatira kolondola kwazochita pambuyo pozindikira zolinga zoyesa ndikukonzekereratu zida zoyezetsa ASANAperekedwe kwa kasitomala. Zachidziwikire, pali makasitomala okhulupirika popanda mwachangu, koma izi ndizosiyana. Iwo. seti yathunthu iyenera kusonkhanitsidwa pamalo a mnzake, zonse zifufuzidwe ndikusonkhanitsidwa. Dongosolo liyenera kukhala likuyenda ndipo muyenera kuwonetsetsa kuti chilichonse chikugwira ntchito, pulogalamuyo imagawidwa popanda zolakwika, ndi zina. Zingawoneke ngati zovuta, koma 3 mwa oyendetsa ndege anayi amayamba ndikuyang'ana zingwe kapena ma transceivers a SFP.
Payokha, ziyenera kutsindika kuti monga gawo loyang'ana machitidwe owonetsera, muyenera kuwonetsetsa kuti ndi oyera. Deta yonse yoyezetsa yam'mbuyomu iyenera kuchotsedwa padongosolo musanasamutsidwe. N'zotheka kuti kuyesa kunachitika pa deta yeniyeni, ndipo pakhoza kukhala chirichonse pamenepo, kuphatikizapo zinsinsi zamalonda ndi deta yaumwini.
Pulogalamu yoyesera
Zida zisanasamutsidwe kwa kasitomala, pulogalamu yoyesera iyenera kukonzekera yomwe ikukwaniritsa zolinga zoyesa. Mayeso aliwonse ayenera kukhala ndi zotsatira zoyezeka komanso zomveka bwino kuti apambane.
Pulogalamu yoyesera imatha kukonzedwa ndi wogulitsa, mnzake, kasitomala, kapena limodzi - koma nthawi zonse ASATANANIKE mayeso. Ndipo kasitomala ayenera kusaina kuti wakhutira ndi pulogalamuyi.
anthu
Monga gawo la kukonzekera woyendetsa ndege, ndikofunikira kuvomereza masiku a woyendetsa ndege ndi kukhalapo kwa anthu onse ofunikira komanso kukonzekera kwawo kuyesa, onse pa gawo la wogulitsa / mnzanu komanso kwa kasitomala. O, oyendetsa ndege angati anayamba ndi munthu wamkulu mu woyendetsa kasitomala kupita kutchuthi tsiku lotsatira kuika zida!
Madera omwe ali ndi udindo / mwayi
Dongosolo la woyendetsa liyenera kumvetsetsa bwino lomwe ndikulongosola bwino lomwe udindo wa anthu onse okhudzidwa. Ngati ndi kotheka, kupeza kwakutali kapena kwakuthupi kwa ogulitsa / opanga mabwenzi ku machitidwe a kasitomala ndi deta zakhala zikugwirizana ndi chitetezo cha kasitomala.
Woyendetsa ndegeyo
Ngati tamaliza mfundo zonse zam'mbuyo, ndiye kuti gawo lotopetsa kwambiri ndi woyendetsa ndegeyo. Koma iyenera kuyenda ngati panjanji. Ngati sichoncho, ndiye kuti gawo lina la kukonzekera lidasokonezedwa.
Kumaliza kwa woyendetsa ndege
Pambuyo pomaliza woyendetsa, chikalata chimakonzedwa pa kuyesa kochitidwa. Momwemo, ndi mayeso onse omwe ali mu pulogalamuyi okhala ndi cheke chobiriwira cha PASS. N'zotheka kukonzekera ulaliki kwa akuluakulu akuluakulu kuti apange chisankho chabwino pa kugula kapena kuphatikizidwa pamndandanda wa machitidwe ovomerezeka kuti agulidwe.
Ngati mulibe chikalata m'manja mwanu kumapeto kwa woyendetsa ndi mndandanda wa mayeso omalizidwa ndi zizindikiro zadutsa, woyendetsa ndegeyo walephera ndipo sayenera kuyambika nkomwe.
