Molweni nonke! Ngeli nqaku, i-AERODISK ivula iblogi kuHabré. Hey, maqabane!
Amanqaku angaphambili kuHabré axubushe ngemibuzo malunga noyilo kunye noqwalaselo olusisiseko lweenkqubo zokugcina. Kweli nqaku siza kuqwalasela umbuzo ongazange ugutyungelwe ngaphambili, kodwa uvame ukubuzwa - malunga nokunyamezela impazamo kwiinkqubo zokugcina i-AERODISK ENGINE. Iqela lethu liya kwenza konke ukuqinisekisa ukuba inkqubo yokugcina i-AERODISK iyeka ukusebenza, oko kukuthi. yaphule.
Kwenzeka ukuba amanqaku malunga nembali yenkampani yethu, malunga neemveliso zethu, kunye nomzekelo wokuphunyezwa ngempumelelo sele exhonywe kwi-Habré, Sibulela kakhulu kumaqabane ethu - iTS Solution kunye neenkampani zeSoftline.
Ke ngoko, andizukuqeqesha izakhono zolawulo lokukopa-uncamathisele apha, kodwa ndiya kubonelela ngokulula amakhonkco kwimvelaphi yala manqaku:
Ndikwafuna ukwabelana ngeendaba ezimnandi. Kodwa ndiza kuqala, ewe, ngengxaki. Thina, njengomthengisi oselula, phakathi kwezinye iindleko, sihlala sijongene nenyaniso yokuba iinjineli ezininzi kunye nabalawuli abazi nje indlela yokusebenzisa kakuhle inkqubo yethu yokugcina.
Kucacile ukuba ukulawula iinkqubo ezininzi zokugcina zibukeka zifana ngokufanayo kumbono womlawuli, kodwa umenzi ngamnye uneempawu zakhe. Kwaye nathi asingomkhethe apha.
Ngoko ke, ukuze wenziwe lula umsebenzi wokuqeqesha iingcali ze-IT, sigqibe kwelokuba sinikele kulo nyaka kwimfundo yasimahla. Ukwenza oku, kwizixeko ezininzi ezikhulu zaseRashiya sivula uthungelwano lwamaZiko oBuchule be-AERODIS, apho nayiphi na ingcali yezobugcisa enomdla inokuthatha ikhosi ngaphandle kwentlawulo kwaye ifumane isatifikethi sokulawula iinkqubo zokugcina i-AERODISK ENGINE.
KwiZiko loBuchule ngalinye siya kufakela idemo stand egcwele ngokupheleleyo esuka kwisistim ye-AERODISK yokugcina kunye ne-physical server, apho utitshala wethu aya kuqhuba uqeqesho lobuso ngobuso. Siza kupapasha ishedyuli yomsebenzi wamaZiko oBuchule ekubonakaleni kwawo, kodwa sele sivule iziko eNizhny Novgorod kwaye isixeko saseKrasnodar silandelayo. Ungabhalisela uqeqesho usebenzisa amakhonkco angezantsi. Nalu ulwazi lwangoku olwaziwayo malunga nezixeko kunye nemihla:

- Qinisekisa ukuba ulwazi olukwiilog luboniswe ngokuchanekileyo.
Ukulungiselela inginginya kunye nenkqubo yokugcina
Siqwalasele ukufikelela kwibhloko kwinkqubo yokugcina usebenzisa i-FC kunye ne-Ethernet port (i-FC kunye ne-iSCSI, ngokulandelanayo). Abafana abavela kwi-TS Solution bachaze ngokweenkcukacha indlela yokwenza oku kwinqaku elidlulileyo (). Kwaye, ngokuqinisekileyo, akukho mntu urhoxise iincwadana kunye nezifundo.
Saseta iqela lemixube sisebenzisa zonke iidrive esinazo. Iidiski ze-2 SSD zongezwa kwi-cache, iidiski ze-2 SSD zongezwa njenge-tier yokugcina eyongezelelweyo (i-Online-tier). Sahlula i-12 SAS10k drives kwi-RAID-60P (i-triple parity) ukwenzela ukujonga ukungaphumeleli kwee-drive ezintathu kwiqela kanye. Idiski enye yayishiywe ukuze ifakwe endaweni yayo.
Siqhagamshele ii-LUN ezimbini (enye nge-FC, enye nge-iSCSI).
Umnini wazo zombini ii-LUN ngumlawuli we-Engine-0
Masiqale uvavanyo
Senza i-IOMETER ngoqwalaselo olungentla.
Sirekhoda i-throughput ye-1.8 GB / s kunye ne-latency ye-3 milliseconds. Akukho ziphoso (Inani lemposiso iyonke).
Ngexesha elifanayo, ukusuka kwi-drive yendawo "C" yomninimzi wethu, ngokufanayo siqala ukukopisha iifayile ezimbini ezinkulu ze-100GB kwi-FC kunye ne-iSCSI yokugcina i-LUNs (i-drives E kunye ne-G kwi-Windows), isebenzisa ezinye ii-interfaces.
Ngentla yinkqubo yokukopa kwi-LUN FC, ngezantsi kwi-iSCSI.
Uvavanyo #1: Ukukhubaza izibuko ze-I / O
Sisondela kwinkqubo yokugcina ngasemva))) kunye nokunyakaza okuncinci kwesandla sikhupha zonke iintambo ze-FC kunye ne-Ethernet 10G kwi-Engine-0 controller. Kufana nokuba inkosikazi yokucoca ene-mop yahamba kwaye yagqiba ekubeni ihlambe umgangatho apho i-snot ilala khona kwaye iintambo zilele (oko kukuthi umlawuli usasebenza, kodwa i-I / O izibuko zifile).
Makhe sijonge kwi-IOMETER kunye nokukopa iifayile. Ukugqithisa kwehle kwi-0,5 GB / s, kodwa ngokukhawuleza kubuyele kwinqanaba langaphambili (malunga ne-4-5 imizuzwana). Akukho zimpazamo.
Ukukhuphela iifayile akuyekanga, kukho ukuhla kwesantya, kodwa akukho nto ibalulekileyo (ukusuka kwi-840 MB / s yehla ukuya kwi-720 MB / s). Ukukopa akuyekanga.
Sijonga iilogi zenkqubo yokugcina kwaye sibone umyalezo malunga nokungafumaneki kwamazibuko kunye nokufuduka ngokuzenzekelayo kweqela.
Iphaneli yolwazi ikwasixelela ukuba yonke into ayilunganga kakhulu kumazibuko eFC.
Inkqubo yokugcina yasinda ukusilela kwe-I/O izibuko ngempumelelo.
Uvavanyo lweNombolo ye-2. Ukukhubaza umlawuli wokugcina
Phantse kwangoko (emva kokuba siqhagamshele iintambo kwakhona kwinkqubo yokugcina) sagqiba kwelokuba sigqibezele inkqubo yokugcina ngokukhupha umlawuli kwi-chassis.
Kwakhona sisondela kwinkqubo yokugcina ngasemva (esiyithandayo))) kwaye ngeli xesha sikhupha umlawuli we-Engine-1, okwangoku ngumnini we-RDG (apho iqela lihamba khona).
Imeko kwi-IOmeter imi ngolu hlobo lulandelayo. I/O ndiyeke malunga nemizuzwana emi-5. Iimpazamo aziqokeleli.
Emva kwemizuzwana emi-5, i-I/O iphinde yaqala kwakhona malunga nokuphuma okufanayo, kodwa nge-latencies ye-35 millisecond (i-latencies yalungiswa emva kwemizuzu embalwa). Njengoko kunokubonwa kwi-screenshots, i-Total error count value yi-0, oko kukuthi, akukho mpazamo yokubhala okanye yokufunda.
Makhe sijonge ukukopa iifayile zethu. Njengoko ubona, ayizange iphazamiseke, kukho ukuhla okuncinci ekusebenzeni, kodwa yonke into ibuyele kwi-~ 800 MB / s efanayo.
Siya kwinkqubo yokugcina kwaye sibone isiqalekiso kwipaneli yolwazi ukuba umlawuli we-Injini-1 akafumaneki (ngokuqinisekileyo, siyibulele).
Kwakhona sibona ukungena okufanayo kwiilogi.
Umlawuli wokugcina uphinde wasinda ukusilela ngempumelelo.
Uvavanyo lwe-3: Ukuqhawula unikezelo lwamandla.
Nje ukuba kunokwenzeka, siqale ukukopa iifayile kwakhona, kodwa asizange siyeke i-IOMETER.
Sitsala iyunithi yonikezelo lwamandla.
Esinye isilumkiso songeziwe kwisixokelelwano sokugcina kwindawo yolwazi.
Kwakhona kwimenyu yabenzi boluvo sibona ukuba abenzi boluvo abanxulumene nonikezelo lwamandla olukhutshiweyo bajike babomvu.
Inkqubo yokugcina iyaqhubeka nokusebenza. Ukungaphumeleli kweyunithi yonikezelo lwamandla akuchaphazeli nangayiphi na indlela ukusebenza kwenkqubo yokugcina; ukusuka kwindawo yokujonga i-host host, isantya sekopi kunye nezikhombisi ze-IOMETER zahlala zingatshintshi.
Uvavanyo lokusilela kwamandla luphumelele ngempumelelo.
Ngaphambi kovavanyo lokugqibela, sagqiba ekubeni sibuyisele inkqubo yogcino ebomini kancinci, sibuyisele isilawuli kunye neyunithi yonikezelo lwamandla, kwaye sibeke iintambo ngokulandelelana, apho inkqubo yokugcina isixelele ngovuyo ngee-icon eziluhlaza kwiphaneli yayo yezempilo. .
Uvavanyo lweNombolo 4. Ukungaphumeleli kweediski ezintathu kwiqela
Ngaphambi kolu vavanyo, senze inyathelo elongezelelweyo lokulungiselela. Inyaniso kukuba inkqubo yokugcina i-ENGINE inikeza into eluncedo kakhulu - imigaqo-nkqubo eyahlukeneyo yokwakha kwakhona. I-TS Solution ibhale ngeli nqaku ngaphambili, kodwa masikhumbule undoqo wayo. Umlawuli wogcino unokucacisa okuphambili kulwabiwo lwezibonelelo ngexesha lokwakha kwakhona. Nokuba kwicala lentsebenzo ye-I / O, oko kukuthi, ukwakhiwa kwakhona kuthatha ixesha elide, kodwa akukho kwehla kokusebenza. Okanye kwicala lesantya sokwakha kwakhona, kodwa imveliso iya kuncitshiswa. Okanye ukhetho olulungeleleneyo. Ekubeni ukusebenza kokugcinwa ngexesha lokwakhiwa kweqela le-disk lihlala liyintloko ye-admin, siya kuvavanya umgaqo-nkqubo kunye ne-bias ngokubhekiselele ekusebenzeni kwe-I / O kunye neendleko zesantya sokuvuselela.
Ngoku makhe sijonge ukusilela kwidisk. Sikwavumela ukurekhoda kwii-LUNs (iifayile kunye ne-IOMETER). Ekubeni sineqela eline-triple parity (RAID-60P), oku kuthetha ukuba inkqubo kufuneka imelane nokungaphumeleli kweediski ezintathu, kwaye emva kokusilela, ukutshintshwa kwe-auto kufuneka kusebenze, idiski enye kufuneka ithathe indawo yenye yezo zihlulekile. kwi-RDG, kwaye ukwakha kwakhona kufuneka kuqale kuyo.
Qala. Okokuqala, ngokusebenzisa ujongano lokugcina, makhe sigxininise iidiski esifuna ukuzikhupha (ukuze singaphuthelwa kwaye sitsale idiski yokutshintsha ngokuzenzekelayo).
Sijonga isalathisi kwi-hardware. Yonke into ilungile, sibona iidiski ezintathu eziphawulweyo.
Kwaye sikhupha ezi diski zintathu.
Makhe sijonge into ekumamkeli. Kwaye akukho nto ikhethekileyo eyenzekayo.
Iimpawu zokukopisha (ziphezulu kunezokuqala, kuba i-cache ifudumala) kwaye i-IOMETER ayitshintshi kakhulu xa isusa iidiski kwaye iqala ukwakhiwa kwakhona (ngaphakathi kwe-5-10%).
Makhe sijonge kwinto ekwinkqubo yokugcina.
Kwimeko yeqela, sibona ukuba inkqubo yohlengahlengiso iqalile kwaye isondele ekugqityweni.
Kwi-RDG skeleton unokubona ukuba iidiski ezi-2 zikwisimo esibomvu, kwaye enye sele itshintshiwe. I-autoreplacement disk ayisekho; ithathe indawo yediski yesi-3 engaphumelelanga. Ukwakhiwa kwakhona kuthathe imizuzu emininzi, ukubhala iifayile xa iidiski ze-3 zingaphumelelanga azizange ziphazamiseke, kwaye ukusebenza kwe-I / O akuzange kutshintshe kakhulu.
Uvavanyo lokungaphumeleli kwediski luphumelele ngokuqinisekileyo ngempumelelo.
isiphelo
Ngeli xesha, sagqiba ekubeni siyeke ubundlobongela kwiinkqubo zokugcina. Masishwankathele:
- Ukuhlolwa kokusilela kwezibuko leFC - kuphumelele
- Ukuhlolwa kwe-Ethernet port ukusilela-kuphumelele
- Ukuhlolwa kokusilela komlawuli - kuphumelele
- Uvavanyo lokungaphumeleli kwamandla - luphumelele
- Ukukhangela ukungaphumeleli kwedisk kwi-grouppool-iphumelele
Akukho nanye kwiintsilelo eziyekile ukurekhoda okanye ezibangele iimpazamo kumthwalo wokwenziwa; ewe, bekukho ukubetha kwentsebenzo (kwaye siyayazi indlela yokuyoyisa, esiya kuyenza kungekudala), kodwa ngenxa yokuba le yimizuzwana, yamkelekile. Isiphelo: ukunyamezela kwephutha kuzo zonke iinxalenye zenkqubo yokugcina i-AERODISK esebenza kwinqanaba, akukho manqaku angaphumeleli.
Ngokucacileyo, kwelinye inqaku asinakuvavanya zonke iimeko zokungaphumeleli, kodwa sizame ukugubungela ezona zidumileyo. Ke ngoko, nceda uthumele izimvo zakho, iingcebiso malunga nokupapashwa kwexesha elizayo kwaye, ngokuqinisekileyo, ukugxeka okwaneleyo. Siya kukuvuyela ukuxoxa (okanye ngcono okwangoku, yiza kuqeqesho, ndiphindaphinda ishedyuli ukuba kunokwenzeka)! De iimvavanyo ezintsha!
