Kupitiliza kulingalira zaukadaulo wofulumizitsa ntchito za I/O monga momwe zimagwiritsidwira ntchito pamakina osungira, zidayamba mu , munthu sangachitire mwina koma kukhala pa njira yotchuka kwambiri monga Auto Tiering. Ngakhale malingaliro a ntchitoyi ndi ofanana kwambiri pakati pa opanga makina osiyanasiyana osungira, tiwona mawonekedwe a kukhazikitsidwa kwa tiering pogwiritsa ntchito chitsanzo. .
Ngakhale kuti pali mitundu yosiyanasiyana ya deta yomwe imasungidwa pamakina osungira, deta yomweyi ikhoza kugawidwa m'magulu angapo malinga ndi zofuna zawo (kawirikawiri ntchito). Deta yodziwika kwambiri ("yotentha") iyenera kupezeka mwamsanga, pamene deta yosagwiritsidwa ntchito ("ozizira") ingasinthidwe mocheperapo.
Kupanga chiwembu chotere, magwiridwe antchito amagwiritsidwa ntchito. Deta ya data pankhaniyi sikhala ndi ma disks amtundu womwewo, koma magulu angapo a ma drive omwe amapanga magawo osiyanasiyana osungira. Pogwiritsa ntchito ma aligorivimu apadera, deta imasunthidwa yokha pakati pamilingo kuti zitsimikizire magwiridwe antchito onse.
Zithunzi za SHD kuthandizira mpaka magawo atatu osungira:
- Gawo 1: SSD, magwiridwe antchito kwambiri
- Gawo 2: HDD SAS 10K/15K, magwiridwe antchito apamwamba
- Gawo 3: HDD NL-SAS 7.2K, kuchuluka kwakukulu
Dziwe la Auto Tiering litha kukhala ndi magawo atatu, kapena awiri okha kuphatikiza kulikonse. Mugawo lililonse, zoyendetsa zimaphatikizidwa m'magulu odziwika bwino a RAID. Kuti muzitha kusinthasintha kwambiri, mulingo wa RAID mu Gawo lililonse ukhoza kukhala wosiyana. Ndiye kuti, mwachitsanzo, palibe chomwe chimakulepheretsani kukonza dongosolo ngati 4x SSD RAID10 + 6x HDD 10K RAID5 + 12 HDD 7.2K RAID6
Pambuyo popanga ma voliyumu (ma disks enieni) pa pool pa iyo imayamba kusonkhanitsa zakumbuyo kwa ziwerengero za ntchito zonse za I/O. Kuti muchite izi, malowa "amadulidwa" mu midadada ya 1GB (yotchedwa sub LUN). Nthawi iliyonse chipika choterechi chikapezeka, chimapatsidwa coefficient ya 1. Kenaka, pakapita nthawi, coefficient iyi imachepa. Pambuyo pa maola 24, ngati palibe zopempha za I / O ku chipikachi, chidzakhala chofanana ndi 0.5 ndipo chidzapitirira kugwa ola lililonse lotsatira.
Panthawi ina (mwachisawawa, tsiku lililonse pakati pausiku), zotsatira zomwe zasonkhanitsidwa zimayikidwa pamagulu ang'onoang'ono a LUN kutengera ma coefficients awo. Kutengera izi, chigamulo chimapangidwa kuti midadada isunthike ndi mbali iti. Pambuyo pake, kusuntha kwa deta pakati pa magawo kumachitika.
Makina osungira a Qsan amakwaniritsa bwino kasamalidwe ka njira yolumikizirana pogwiritsa ntchito magawo ambiri, omwe amakupatsani mwayi wosintha magwiridwe antchito omaliza.
Kuti mudziwe malo oyamba a deta komanso momwe amayendera patsogolo, ndondomeko zimagwiritsidwa ntchito zomwe zimayikidwa padera pa voliyumu iliyonse:
- Kukonzekera kwa Auto - ndondomeko yosasinthika, kuyika koyambirira ndi mayendedwe a kayendetsedwe ka kayendetsedwe kake zimatsimikiziridwa zokha, i.e. Deta "yotentha" imakhala pamwamba, ndipo deta "yozizira" imatsika. Kuyika koyamba kumasankhidwa kutengera malo omwe alipo pamlingo uliwonse. Koma muyenera kumvetsetsa kuti makinawo amayesetsa kugwiritsa ntchito kwambiri ma drive othamanga kwambiri. Choncho, ngati pali malo omasuka, deta idzayikidwa pamwamba. Ndondomekoyi ndi yoyenera pazochitika zambiri zomwe kufunikira kwa deta sikungathe kuneneratu pasadakhale.
- Yambani ndi High ndiyeno Auto Tiering - kusiyana ndi komweku kumangokhala komwe kuli koyambirira kwa data (pamlingo wachangu)
- Mulingo wapamwamba kwambiri - data nthawi zonse imayesetsa kukhala yothamanga kwambiri. Ngati asunthidwa pansi panthawi yogwira ntchito, ndiye kuti mwamsanga amabwereranso. Ndondomekoyi ndi yoyenera pa data yomwe imafuna kuti anthu azitha kupeza mofulumira kwambiri.
- Osachepera msinkhu - data nthawi zonse imakhala yotsika kwambiri. Lamuloli ndilabwino pa data yomwe simagwiritsidwa ntchito kawirikawiri (mwachitsanzo, zakale).
- Palibe kusuntha - dongosololi limasankha malo oyambirira a deta ndipo silisuntha. Komabe, ziwerengero zikupitiriza kusonkhanitsidwa ngati kusamutsidwa kwawo kudzafunika.
Ndikoyenera kudziwa kuti ngakhale ndondomeko zimatanthauzidwa pamene voliyumu iliyonse yapangidwa, imatha kusinthidwa mobwerezabwereza panthawi yonse ya moyo wa dongosolo.
Kuphatikiza pa ndondomeko zamakina a tiering, mafupipafupi ndi liwiro la kayendetsedwe ka deta pakati pa magawo amakonzedwanso. Mutha kukhazikitsa nthawi yoyenda: tsiku lililonse kapena masiku ena a sabata, komanso kuchepetsa nthawi yosonkhanitsa ziwerengero mpaka maola angapo (mafupipafupi - 2 hours). Ngati mukufuna kuchepetsa nthawi yomwe imafunika kuti mutsirize ntchito yosuntha deta, mukhoza kukhazikitsa nthawi (zenera losuntha). Kuphatikiza apo, liwiro losamuka likuwonetsedwanso - mitundu 3: mwachangu, sing'anga, pang'onopang'ono.
Ngati pakufunika kusamutsa deta mwamsanga, n'zotheka kuchita pamanja nthawi iliyonse pa lamulo la woyang'anira.
Zikuwonekeratu kuti nthawi zambiri komanso mofulumira deta imasunthidwa pakati pa milingo, njira yosungiramo yosungiramo zinthu zosinthika idzakhala yogwirizana ndi zomwe zikuchitika panopa. Koma panthawi imodzimodziyo, ndi bwino kukumbukira kuti kusuntha ndi katundu wowonjezera (makamaka pa disks), kotero simuyenera "kuyendetsa" deta pokhapokha ngati kuli kofunikira. Ndi bwino kukonzekera kusuntha panthawi ya katundu wochepa. Ngati ntchito yosungiramo zinthu zosungirako nthawi zonse imafuna kugwira ntchito kwambiri 24/7, ndiye kuti ndi bwino kuchepetsa kusamuka kukhala kochepa.
Kuchuluka kwa makonda owombera mosakayikira kusangalatsa ogwiritsa ntchito apamwamba. Komabe, kwa iwo omwe amakumana ndi teknoloji yotere kwa nthawi yoyamba, palibe chodetsa nkhaŵa. Ndizotheka kudalira zosintha zosasinthika (ndondomeko ya Auto Tiering, kusuntha mwachangu kamodzi patsiku usiku) ndipo, momwe ziwerengero zimasonkhanitsira, sinthani magawo ena kuti mukwaniritse zomwe mukufuna.
Kuyerekeza kung'ambika ndi ukadaulo womwewo wotchuka pakuwonjezera zokolola ngati , muyenera kukumbukira malamulo osiyanasiyana ogwiritsira ntchito ma aligorivimu awo.
SSD caching
Kukonzekera kwa Auto
Liwiro loyambira
Pafupifupi nthawi yomweyo. Koma zowoneka bwino zimangochitika kuti cache "yatenthedwa" (mphindi mpaka maola)
Mutatha kusonkhanitsa ziwerengero (kuyambira maola awiri, makamaka tsiku) kuphatikiza nthawi yosuntha deta
Kutha kwa nthawi
Mpaka deta italowetsedwa ndi gawo latsopano (maola-miniti)
Pomwe deta ikufunika (maola XNUMX kapena kuposerapo)
Zizindikiro za kugwiritsidwa ntchito
Kupindula kwakanthawi kwakanthawi kochepa (zosungirako zosungirako, madera a virtualization)
Kuchulukitsa kwa zokolola kwa nthawi yayitali (fayilo, intaneti, ma seva amakalata)
Komanso, chimodzi mwazinthu zamagulu ndikuthekera kogwiritsa ntchito osati pazochitika ngati "SSD + HDD", komanso "HDD yofulumira + pang'onopang'ono HDD" kapena milingo yonse itatu, zomwe sizingatheke mukamagwiritsa ntchito posungira SSD.
Kuyesa
Kuyesa magwiridwe antchito a ma algorithms a tiering, tidayesa mayeso osavuta. Dziwe la magawo awiri a SSD (RAID 1) + HDD 7.2K (RAID1) linapangidwa, pomwe voliyumu yokhala ndi ndondomeko ya "minimum level" inayikidwa. Iwo. Deta nthawi zonse iyenera kukhala pa diski yocheperako.
Mawonekedwe owongolera akuwonetsa bwino kuyika kwa data pakati pa magawo
Titadzaza voliyumu ndi data, tidasintha ndondomeko yoyika kukhala Auto Tiering ndikuyesa mayeso a IOmeter.
Pambuyo pa kuyesedwa kwa maola angapo, pamene dongosololi linatha kudziunjikira ziwerengero, ntchito yosamukirako inayamba.
Kusuntha kwa data kutatha, voliyumu yathu yoyeserera kwathunthu "inakwawa" kupita kumtunda wapamwamba (SSD).
Vuto
Auto Tiering ndiukadaulo wodabwitsa womwe umakupatsani mwayi wowonjezera magwiridwe antchito osungira omwe ali ndi zinthu zochepa komanso mtengo wanthawi ndikugwiritsa ntchito kwambiri ma drive othamanga kwambiri. Zagwiritsidwa ntchito ku ndalama yokhayo ndi chilolezo, chomwe chimagulidwa kamodzi popanda zoletsa pa voliyumu / chiwerengero cha disks/shelves/etc. Kugwira ntchito kumeneku kumakhala ndi makonda olemera kotero kuti kumatha kukhutiritsa pafupifupi ntchito iliyonse yamabizinesi. Ndipo kuyang'ana njira mu mawonekedwe kukulolani kuti muzitha kuyendetsa bwino chipangizocho.
