Moni nonse! Ndi nkhaniyi, AERODISK imatsegula blog pa Habré. Zikomo, abwenzi!
Zolemba zam'mbuyomu za Habré zidakambilana mafunso okhudza kamangidwe ndi kakhazikitsidwe koyambira kasungidwe kazinthu. M'nkhaniyi tikambirana funso lomwe silinatchulidwepo kale, koma nthawi zambiri limafunsidwa - ponena za kulekerera kolakwika kwa machitidwe osungiramo AERODISK ENGINE. Gulu lathu lidzachita zonse kuti zitsimikizire kuti AERODISK yosungirako dongosolo imasiya kugwira ntchito, i.e. kuswa izo.
Zinachitika kuti nkhani za mbiri ya kampani yathu, zokhudzana ndi katundu wathu, komanso chitsanzo cha kukhazikitsidwa bwino zapachikika pa Habré, zomwe Zikomo kwambiri kwa anzathu - TS Solution ndi makampani a Softline.
Chifukwa chake, sindiphunzitsa luso la kasamalidwe ka makope-paste pano, koma ndingopereka maulalo oyambira zolemba izi:
Ndikufunanso kugawana nawo uthenga wabwino. Koma ndiyamba, ndithudi, ndi vuto. Ife, monga wogulitsa wamng'ono, pakati pa ndalama zina, nthawi zonse timayang'anizana ndi mfundo yakuti akatswiri ambiri ndi olamulira sakudziwa momwe angagwiritsire ntchito bwino makina athu osungira.
Zikuwonekeratu kuti kuyang'anira machitidwe ambiri osungirako kumawoneka mofanana mofanana ndi momwe woyang'anira amaonera, koma wopanga aliyense ali ndi makhalidwe ake. Ndipo ifenso ndife osiyana pano.
Choncho, pofuna kuchepetsa ntchito yophunzitsa akatswiri a IT, tinaganiza zopereka maphunziro aulere chaka chino. Kuti tichite izi, m'mizinda ikuluikulu ya ku Russia tikutsegula maukonde a AERODISK Competence Centers, momwe katswiri aliyense wodziwa zaukadaulo amatha kutenga maphunziro aulere ndi kulandira satifiketi yoyang'anira makina osungira a AERODISK ENGINE.
Mu Chigawo chilichonse cha Competence tidzakhazikitsa chiwonetsero chazithunzi chokwanira kuchokera ku AERODISK yosungirako ndi seva ya thupi, yomwe mphunzitsi wathu adzachititsa maphunziro a maso ndi maso. Tidzasindikiza ndondomeko ya ntchito za Competence Centers pa maonekedwe awo, koma tatsegula kale malo ku Nizhny Novgorod ndipo mzinda wa Krasnodar ndi wotsatira. Mutha kulembetsa ku maphunziro pogwiritsa ntchito maulalo omwe ali pansipa. Nazi zomwe zikudziwika pano zamizinda ndi masiku:
- Nizhny Novgorod (YASUNGULIRA KALE - mutha kulembetsa apa );
Mpaka pa Epulo 16, 2019, mutha kuyendera malowa nthawi iliyonse yogwira ntchito, ndipo pa Epulo 16, 2019, maphunziro akulu adzakonzedwa. - Krasnodar (KUTULUKA POsachedwa - mutha kulembetsa apa );
Kuyambira pa Epulo 9 mpaka Epulo 25, 2019, mutha kupita kumaloko nthawi iliyonse yogwira ntchito, ndipo pa Epulo 25, 2019, maphunziro akulu adzakonzedwa. - Екатеринбург (KUTULUKA POSACHEDWAPA, tsatirani zomwe zili patsamba lathu kapena pa Habré);
May-June 2019. - Новосибирск (tsatirani zomwe zili patsamba lathu kapena pa Habré);
Okutobala 2019. - Красноярск (tsatirani zomwe zili patsamba lathu kapena pa Habré);
Novembala 2019.
Ndipo, ndithudi, ngati Moscow sali kutali ndi inu, ndiye nthawi iliyonse mukhoza kupita ku ofesi yathu ku Moscow ndikuphunziranso chimodzimodzi.
Zonse. Tathana ndi malonda, tiyeni tipitirire kuukadaulo!
Pa Habré tidzasindikiza pafupipafupi zolemba zaukadaulo wazogulitsa zathu, kuyesa kwa katundu, kufananiza, mawonekedwe akugwiritsa ntchito ndi kukhazikitsa kosangalatsa.
Mayeso owonongeka a AERODISK ENGINE N2 yosungirako, kuyesa mphamvu
CHENJEZO! Pambuyo powerenga nkhaniyi, munganene kuti: chabwino, ndithudi, wogulitsa adzifufuza yekha kuti zonse zigwire ntchito "ndi kuphulika," kutentha kwa kutentha, ndi zina zotero. Ndiyankha: palibe chonga chimenecho! Mosiyana ndi opikisana nawo akunja, ife tiri pano, pafupi ndi inu, ndipo mukhoza kubwera kwa ife nthawi zonse (ku Moscow kapena Komiti Yaikulu Yonse) ndikuyesa dongosolo lathu losungiramo njira iliyonse. Chifukwa chake, sizomveka kuti tisinthe zotsatira kukhala chithunzi chabwino cha dziko lapansi, chifukwa Ndife osavuta kufufuza. Kwa iwo omwe ali aulesi kwambiri kuti apite ndipo alibe nthawi, titha kukonza kuyesa kwakutali. Tili ndi labu yapadera ya izi. Lumikizanani nafe.
ACHTUNG-2! Kuyesa uku sikuyesa katundu, chifukwa apa timangoganizira za kulolerana zolakwa. M'masabata angapo, tidzakonzekera kuyimitsidwa kwamphamvu kwambiri ndikuyesa kuyesa kosungirako, kufalitsa zotsatira pano (mwa njira, zopempha zoyesa zimavomerezedwa).
Kotero, tiyeni tipite kuchiswe.
benchi yoyesera
Maimidwe athu ali ndi zida zotsatirazi:
- 1 x Aerodisk Engine N2 yosungirako dongosolo (2 olamulira, 64GB cache, 8xFC madoko 8Gb / s, 4xEthernet madoko 10Gb / s SFP +, 4xEthernet madoko 1Gb / s); Ma disks otsatirawa amaikidwa mu kachitidwe kosungirako:
- 4 x SAS SSD ma disks 900 GB;
- 12 x SAS 10k disks 1,2 TB;
- 1 x Seva yakuthupi yokhala ndi Windows Server 2016 (2xXeon E5 2667 v3, 96GB RAM, 2xFC madoko 8Gb/s, 2xEthernet madoko 10Gb/s SFP+);
- 2 x SAN 8G kusintha;
- 2 x LAN 10G kusintha;
Tinagwirizanitsa seva ku dongosolo losungirako pogwiritsa ntchito masinthidwe kudzera pa FC ndi 10G Ethernet. Chithunzi choyimira chili pansipa.
Zomwe timafunikira, monga MPIO ndi iSCSI initiator, zimayikidwa pa Windows Server.
Magawo amakonzedwa pa ma switch a FC, ma VLAN ofananira amasinthidwa pakusintha kwa LAN, ndipo MTU 9000 imayikidwa pamadoko osungira, ma switch, ndi olandila (momwe mungachitire zonsezi zikufotokozedwa m'malemba athu, kotero sitingafotokoze. ndondomeko iyi apa).
Njira yoyesera
Dongosolo loyeserera kuwonongeka lili motere:
- Kuwona kulephera kwa madoko a FC ndi Ethernet.
- cheke kulephera kwa mphamvu.
- Kuwona kulephera kwa owongolera.
- Kuyang'ana kulephera kwa disk mu gulu/dziwe.
Mayesero onse adzachitidwa pansi pa katundu wopangidwa, zomwe tidzapanga ndi pulogalamu ya IOMETER. Mofananamo, tidzachita mayesero omwewo, koma pansi pa zikhalidwe zokopera mafayilo akuluakulu kumalo osungirako.
Kukonzekera kwa IOmeter kuli motere:
- Werengani/Lembani - 70/30
- Block - 128k (tinaganiza zotsuka makina osungira muzitsulo zazikulu)
- Chiwerengero cha ulusi - 128 (omwe ali ofanana kwambiri ndi katundu wobala)
- Zonse Mwachisawawa
- Chiwerengero cha Antchito - 4 (2 a FC, 2 a iSCSI)
Mayesowa ali ndi zolinga izi:
- Onetsetsani kuti kupanga katundu ndi kukopera ndondomeko sizidzasokoneza kapena kuyambitsa zolakwika pansi pa zochitika zosiyanasiyana zolephera.
- Onetsetsani kuti njira yosinthira madoko, olamulira, ndi zina zambiri ndizodziwikiratu ndipo sizifuna zochita za woyang'anira ngati zalephera (ndiko kuti, panthawi yolephera, sitikulankhula za zolakwika, inde).
- Onetsetsani kuti zomwe zili m'zipika zikuwonetsedwa bwino.
Kukonzekera kosungirako ndi kusungirako
Tidakonza zofikira pamakina osungira pogwiritsa ntchito madoko a FC ndi Ethernet (FC ndi iSCSI, motsatana). Anyamata ochokera ku TS Solution adalongosola mwatsatanetsatane momwe angachitire izi m'nkhani yapitayi (). Ndipo, ndithudi, palibe amene analetsa mabuku ndi maphunziro.
Tinakhazikitsa gulu la haibridi pogwiritsa ntchito ma drive onse omwe tinali nawo. Ma disks a 2 SSD adawonjezedwa ku cache, ma disks a 2 SSD adawonjezedwa ngati gawo losungirako (Online-tier). Tidayika ma drive 12 SAS10k mu RAID-60P (parity parity) kuti tiwone kulephera kwa ma drive atatu pagulu nthawi imodzi. Disiki imodzi idasiyidwa kuti ilowe m'malo.
Tidalumikiza ma LUN awiri (imodzi kudzera pa FC, imodzi kudzera pa iSCSI).
Mwini wake wa LUNs onse ndi Engine-0 controller
Tiyeni tiyambe mayeso
Timatsegula IOMETER ndi kasinthidwe pamwambapa.
Timalemba ma 1.8 GB/s ndi latency ya 3 milliseconds. Palibe zolakwika (Total Error Count).
Panthawi imodzimodziyo, kuchokera pagalimoto yapafupi "C" ya wolandira wathu, timayambanso kukopera mafayilo awiri akuluakulu a 100GB ku FC ndi iSCSI yosungirako LUNs (amayendetsa E ndi G mu Windows), pogwiritsa ntchito mawonekedwe ena.
Pamwambapa pali njira yokopera ku LUN FC, pansipa ku iSCSI.
Mayeso #1: Kuletsa madoko a I / O
Timayandikira kusungirako kuchokera kumbuyo))) ndipo ndikuyenda pang'ono kwa dzanja timatulutsa zingwe zonse za FC ndi Ethernet 10G kuchokera kwa wolamulira wa Engine-0. Zili ngati kuti dona woyeretsa wokhala ndi mop adadutsa ndipo adaganiza zotsuka pansi pomwe panali snot ndipo zingwe zidagona (ie wolamulira akugwirabe ntchito, koma madoko a I / O afa).
Tiyeni tiwone IOMETER ndikukopera mafayilo. Kutulutsa kudatsikira ku 0,5 GB / s, koma mwachangu kubwerera kumlingo wake wakale (pafupifupi masekondi 4-5). Palibe zolakwika.
Kukopera mafayilo sikunayime, pali kutsika kwa liwiro, koma sikovuta konse (kuchokera ku 840 MB / s kutsika mpaka 720 MB / s). Kukopera sikunayime.
Timayang'ana zolemba zosungirako zosungirako ndikuwona uthenga wonena za kusapezeka kwa madoko komanso kusamutsidwa kwa gululo.
Gulu lazidziwitso limatiuzanso kuti zonse sizili bwino ndi madoko a FC.
Makina osungira adapulumuka kulephera kwa madoko a I / O bwino.
Mayesero No. 2. Kulepheretsa woyang'anira yosungirako
Pafupifupi nthawi yomweyo (titatha kulumikiza zingwe m'malo osungira) tinaganiza zomaliza kusungirako potulutsa wowongolera mu chassis.
Apanso timayandikira kusungirako kuchokera kumbuyo (tinkakonda))) ndipo nthawi ino timatulutsa wolamulira wa Engine-1, yemwe panthawiyi ndi mwini wake wa RDG (kumene gulu linasamukira).
Zomwe zili mu IOmeter zili motere. I/O anayima pafupifupi masekondi asanu. Zolakwa siziunjikana.
Pambuyo pa masekondi a 5, I/O inayambiranso ndi kutulutsa komweko, koma ndi latency ya 35 milliseconds (ma latency adakonzedwa pakatha mphindi zingapo). Monga tikuwonera pazithunzi, kuchuluka kwa zolakwika zonse ndi 0, ndiye kuti, panalibe zolakwika zolembera kapena kuwerenga.
Tiyeni tiwone kukopera mafayilo athu. Monga mukuwonera, sizinasokonezedwe, panali kutsika pang'ono, koma zonse zidabwereranso chimodzimodzi ~ 800 MB/s.
Timapita kumalo osungiramo zinthu ndikuwona temberero mu gulu lazidziwitso kuti wolamulira wa Engine-1 sakupezeka (zowona, tinamupha).
Timawonanso cholowa chofananira mu zipika.
Woyang'anira yosungirako adapulumukanso kulephera bwino.
Mayeso 3: Kuchotsa magetsi.
Zikatero, tinayambanso kukopera mafayilo, koma sitinayime IOMETER.
Timakoka gawo lamagetsi.
Chenjezo lina lawonjezeredwa ku kachitidwe kosungirako mu gulu lazidziwitso.
Komanso mu menyu ya masensa tikuwona kuti masensa omwe amalumikizidwa ndi magetsi otulutsidwa asanduka ofiira.
Njira yosungirako ikupitiriza kugwira ntchito. Kulephera kwa gawo loperekera mphamvu sikumakhudza njira iliyonse yosungiramo ntchito; kuchokera kwa wolandirayo, liwiro la kukopera ndi zizindikiro za IOMETER sizinasinthe.
Kulephera kwa mphamvu kwadutsa bwino.
Kuyesedwa komaliza kusanachitike, tinaganiza zobweretsanso zosungirako pang'ono, kubwezera chowongolera ndi magetsi, ndikuyikanso zingwe, zomwe zidatidziwitsa mosangalala ndi zithunzi zobiriwira mu gulu lake laumoyo. .
Mayeso No. 4. Kulephera kwa ma disks atatu mu gulu
Asanayesedwe, tidachitanso gawo lina lokonzekera. Chowonadi ndi chakuti makina osungira ENGINE amapereka chinthu chothandiza kwambiri - ndondomeko zosiyana zomanganso. TS Solution idalemba za izi kale, koma tiyeni tikumbukire tanthauzo lake. Woyang'anira zosungirako akhoza kufotokoza zofunikira pakugawidwa kwazinthu panthawi yomanganso. Kaya kumayendedwe a I / O, ndiye kuti, kumanganso kumatenga nthawi yayitali, koma palibe kutsika kwa magwiridwe antchito. Kapena kutsogolera liwiro kumanganso, koma zokolola zidzachepetsedwa. Kapena njira yoyenera. Popeza ntchito yosungiramo nthawi yomanganso gulu la disk nthawi zonse imakhala mutu wa admin, tidzayesa ndondomeko ndi tsankho pa ntchito ya I / O komanso pamtengo womanganso liwiro.
Tsopano tiyeni tione ngati litayamba kulephera. Timathandiziranso kujambula ku LUNs (mafayilo ndi IOMETER). Popeza tili ndi gulu lokhala ndi parity katatu (RAID-60P), izi zikutanthauza kuti dongosololi liyenera kupirira kulephera kwa ma disks atatu, ndipo pambuyo pa kulephera, kusintha kwa magalimoto kuyenera kugwira ntchito, disk imodzi iyenera kutenga malo a imodzi mwazolephera. mu RDG, ndikumanganso kuyenera kuyamba pamenepo.
Yamba. Choyamba, kudzera muzosungirako zosungirako, tiyeni tiwonetsere ma disks omwe tikufuna kuchotsa (kuti tisaphonye ndi kukoka disk yosintha).
Timayang'ana chizindikiro pa hardware. Chilichonse chili bwino, tikuwona ma disks atatu owunikira.
Ndipo timatulutsa ma disks atatu awa.
Tiyeni tiwone zomwe zili pa wolandila. Ndipo apo... palibe chapadera chinachitika.
Zizindikiro zokopera (ndizokwera kuposa pachiyambi, chifukwa cache yatenthedwa) ndipo IOMETER sizisintha kwambiri pochotsa ma disks ndikuyambanso kumanganso (mkati mwa 5-10%).
Tiyeni tiwone zomwe zili pamakina osungira.
Momwe gululi lilili, tikuwona kuti ntchito yokonzanso yayamba ndipo ili pafupi kutha.
Mu mafupa a RDG mutha kuwona kuti ma disk 2 ali ofiira, ndipo imodzi yasinthidwa kale. The autoreplacement disk kulibenso; idalowa m'malo mwa 3rd idalephera disk. Kumanganso kunatenga mphindi zingapo, kulemba mafayilo pamene 3 disks inalephera sikunasokonezedwe, ndipo ntchito ya I / O sinasinthe kwambiri.
Kuyesa kwa disk kulephera kwadutsa ndithu bwino.
Pomaliza
Panthawiyi, tinaganiza zosiya chiwawa chotsutsana ndi machitidwe osungira. Tiyeni tifotokoze mwachidule:
- Kuwunika kwa doko la FC - zapambana
- Kuwunika kwa doko la Ethernet - kopambana
- Kuwona kulephera kwa owongolera - kopambana
- Kulephera Kuyesa Mphamvu - Zapambana
- Kuyang'ana kulephera kwa disk mu grouppool - bwino
Palibe cholephera chomwe chinasiya kujambula kapena kuyambitsa zolakwika pakupanga katundu; zowona, panali kugunda kwamasewera (ndipo tikudziwa momwe tingagonjetsere, zomwe tidzachita posachedwa), koma popeza izi ndi masekondi, ndizovomerezeka. Kutsiliza: kulekerera kolakwa kwa zigawo zonse za AERODISK yosungirako dongosolo linagwira ntchito pamlingo, panalibe mfundo zolephera.
Mwachionekere, m’nkhani ina sitingathe kuyesa zochitika zonse za kulephera, koma tinayesa kutchula zotchuka kwambiri. Chifukwa chake, chonde tumizani ndemanga zanu, malingaliro azofalitsa zamtsogolo ndipo, zowona, kutsutsidwa kokwanira. Tidzakhala okondwa kukambirana (kapena bwinobe, bwerani kumaphunzirowa, ndikubwereza ndandanda pokhapokha)! Mpaka mayesero atsopano!
- Nizhny Novgorod (YASUNGULIRA KALE - mutha kulembetsa apa );
Mpaka pa Epulo 16, 2019, mutha kuyendera malowa nthawi iliyonse yogwira ntchito, ndipo pa Epulo 16, 2019, maphunziro akulu adzakonzedwa. - Krasnodar (KUTULUKA POsachedwa - mutha kulembetsa apa );
