Nyob zoo sawv daws! Raws li tau cog lus tseg, peb tab tom tshaj tawm cov txiaj ntsig ntawm kev ntsuas kev thauj khoom ntawm Lavxias-ua cov ntaub ntawv khaws cia - AERODISK ENGINE N2.
Nyob rau hauv tsab xov xwm dhau los, peb tsoo lub kaw lus cia (uas yog, peb tau ua qhov kev ntsuam xyuas kev sib tsoo) thiab cov txiaj ntsig ntawm kev kuaj kev sib tsoo tau zoo (uas yog, peb tsis tawg lub kaw lus cia). Koj tuaj yeem saib cov txiaj ntsig kev sib tsoo .
Hauv cov lus hais rau tsab xov xwm dhau los, kev thov tau ua ntxiv rau kev ntsuas kev sib tsoo ntau dua. Peb tau sau lawv tag nrho thiab yuav twv yuav raug siv rau hauv ib qho ntawm cov kab lus hauv qab no. Nyob rau tib lub sijhawm, koj tuaj yeem tuaj xyuas peb lub chaw kuaj mob hauv Moscow txhua lub sijhawm (los ntawm ko taw lossis ua nws deb ntawm Is Taws Nem) thiab ua cov kev sim no koj tus kheej (koj tuaj yeem ua qhov kev sim rau ib qhov project tshwj xeeb :-)). Sau ntawv rau peb, peb yuav xav txog txhua yam xwm txheej!
Tsis tas li ntawd, yog tias koj tsis nyob hauv Moscow, koj tseem tuaj yeem paub ntau ntxiv txog peb lub kaw lus cia los ntawm kev koom nrog kev cob qhia pub dawb ntawm lub chaw muaj peev xwm hauv nroog ze tshaj plaws rau koj.
Hauv qab no yog cov npe ntawm cov xwm txheej yav tom ntej thiab hnub ua haujlwm ntawm cov chaw muaj peev xwm.
- Ekaterinburg. Plaub Hlis 16, 2019. Kev cob qhia seminar. Koj tuaj yeem sau npe siv qhov txuas:
- Ekaterinburg. Lub Tsib Hlis 20 - Lub Rau Hli 21, 2019. Competence Center. Tuaj mus rau kev ua qauv qhia nyob ntawm AERODISK ENGINE N2 qhov chaw cia khoom txhua lub sijhawm ua haujlwm. Qhov chaw nyob tseeb thiab qhov txuas rau npe yuav muab tom qab. Ua raws li cov ntaub ntawv.
- Novosibirsk Ua raws li cov ntaub ntawv ntawm peb qhov chaw lossis HUBRA.
Lub kaum hli ntuj 2019 - Kazan. Ua raws li cov ntaub ntawv ntawm peb qhov chaw lossis HUBRA.
Lub kaum hli ntuj 2019 - Krasnoyarsk Ua raws li cov ntaub ntawv ntawm peb qhov chaw lossis HUBRA.

Peb kuj xav qhia ib qho xov xwm zoo ntxiv: peb tau txais thaum kawg channel uas koj tuaj yeem saib cov yeeb yaj kiab los ntawm cov xwm txheej dhau los. Peb niaj hnub tshaj tawm peb cov yeeb yaj kiab kev cob qhia nyob ntawd.
Test sawv
Yog li, rov qab mus rau qhov kev xeem. Peb tau hloov kho peb ENGINE N2 lub chaw soj nstuam cia los ntawm kev txhim kho SAS SSD drives ntxiv, nrog rau Front-end Fiber Channel 16G adapters. Nyob rau hauv ib tug symmetrical yam, peb upgraded lub server los ntawm uas peb yuav khiav lub load los ntawm kev ntxiv FC 16G adapters.
Raws li qhov tshwm sim, hauv peb lub chaw kuaj mob peb muaj 2-tswj lub kaw lus nrog 24 SAS SSD 1,6 TB, 3 DWPD disks, uas txuas nrog SAN hloov mus rau lub cev Linux server ntawm FC 16G.
Daim duab kos duab kos duab tau pom hauv daim duab hauv qab no.
Test Methodology
Rau qhov ua tau zoo tshaj plaws ntawm kev nkag mus thaiv, peb yuav siv DDP (Dynamic Disk Pool) cov pas dej, uas peb ib zaug tsim tshwj xeeb rau ALL-FLASH systems.
Rau kev sim, peb tsim ob lub LUNs nrog lub peev xwm ntawm 1 TB txhua tus nrog RAID-10 qib kev tiv thaiv. Peb yuav "kis" txhua LUN hla 12 disks (24 nyob rau hauv tag nrho) thiaj li yuav siv tau tag nrho cov peev xwm ntawm txhua qhov teeb tsa disks hauv qhov system cia.
Peb nthuav tawm LUNs rau cov neeg rau zaub mov los ntawm cov tswj sib txawv txhawm rau siv cov peev txheej khaws cia ntau li ntau tau.
Txhua qhov kev ntsuam xyuas yuav kav ib teev, thiab cov kev ntsuam xyuas yuav ua los ntawm Flexible IO (FIO) program; FIO cov ntaub ntawv yuav raug xa mus rau Excel, uas cov duab tau tsim kom pom tseeb.
Load Profiles
Nyob rau hauv tag nrho, peb yuav ua peb qhov kev ntsuam xyuas, ib teev txhua, tsis suav nrog lub sij hawm sov so, uas peb yuav faib 15 feeb (qhov no yog raws nraim li cas yuav tsum tau ua kom sov ib array ntawm 24 SSD drives). Cov kev ntsuam xyuas no ua raws li qhov feem ntau ntsib cov ntaub ntawv thauj khoom, tshwj xeeb tshaj yog cov no yog qee yam DBMSs, kev soj ntsuam video, cov ntsiab lus xov xwm tshaj tawm thiab thaub qab.
Tsis tas li ntawd, hauv txhua qhov kev sim, peb txhob txwm ua tsis taus lub peev xwm cache rau hauv RAM ntawm lub kaw lus cia thiab ntawm tus tswv tsev. Tau kawg, qhov no yuav ua rau cov txiaj ntsig tsis zoo, tab sis, hauv peb lub tswv yim, nyob rau hauv cov xwm txheej zoo li no, qhov kev sim yuav zoo dua.
Ntsuas cov txiaj ntsig
Xeem No 1. Random load nyob rau hauv me me blocks. Emulation ntawm high-load pauv DBMS.
- Block loj = 4k
- Nyeem / Sau = 70% / 30%
- Tus lej ua haujlwm = 16
- Qhov tob = 32
- Load character = Full Random
Cov qhabnias xeem:
Nyob rau hauv tag nrho, nrog rau cov junior mid-range Cav N2 system peb tau txais 438k IOPS nrog latency ntawm 2,6 milliseconds. Xav txog cov chav kawm ntawm qhov system, hauv peb lub tswv yim, qhov txiaj ntsig tau zoo heev. Txhawm rau kom nkag siab seb qhov no puas yog qhov txwv rau lub kaw lus, peb yuav saib cov peev txheej siv cov tswj hwm cia.
Peb feem ntau txaus siab rau CPU, txij li, raws li tau hais los saum no, peb txhob txwm ua tsis taus RAM cache kom tsis txhob cuam tshuam cov txiaj ntsig kev xeem.
Ntawm ob lub chaw khaws cia peb pom kwv yees li tib daim duab.
Ntawd yog, CPU load yog 50%. Qhov no qhia tau tias qhov no nyob deb ntawm qhov txwv ntawm qhov kev cia khoom no thiab nws tseem tuaj yeem ntsuas tau yooj yim. Cia peb dhia ua ntej me ntsis: tag nrho cov kev ntsuam xyuas hauv qab no kuj pom tias cov khoom thauj ntawm cov tswj hwm tau nyob ib puag ncig 50%, yog li peb yuav tsis sau lawv dua.
Raws li peb cov kev kuaj sim, qhov kev txwv tsis pub muaj kev nyab xeeb ntawm AERODISK Cav N2 system, yog tias peb suav IOPS random ntawm 4k blocks, yog ~ 700 IOPS. Yog tias qhov no tsis txaus thiab koj yuav tsum siv zog rau ib lab, ces peb muaj cov qauv qub ENGINE N000.
Ntawd yog, zaj dab neeg hais txog ntau lab tus IOPS yog ENGINE N4, thiab yog tias ib lab yog ntau dhau rau koj, ces ua siab ntev siv N2.
Cia peb rov qab mus rau qhov kev xeem.
Test No. 2. Sequential kaw nyob rau hauv loj blocks. Emulation ntawm video soj ntsuam systems, loading cov ntaub ntawv mus rau hauv ib tug analytical DBMS los yog kaw cov ntaub ntawv thaub qab.
Hauv qhov kev sim no peb tsis txaus siab rau IOPS, txij li thaum ua ntu zus hauv cov blocks loj lawv tsis muaj kev nkag siab. Peb feem ntau txaus siab rau: kev sau ntawv ntws (megabytes ib ob) thiab qeeb, uas, tau kawg, yuav siab dua nrog cov blocks loj dua nrog cov me me.
- Block loj = 128k
- Nyeem / Sau = 0% / 100%
- Tus lej ua haujlwm = 16
- Qhov tob = 32
- Load Character β Sequential
Tag nrho: peb muaj cov ntaub ntawv ntawm tsib thiab ib nrab gigabytes ib ob nrog qeeb ntawm kaum ib milliseconds. Thaum piv nrog nws cov neeg sib tw txawv teb chaws ze tshaj plaws, qhov tshwm sim, hauv peb lub tswv yim, zoo heev, thiab tsis yog qhov txwv ntawm ENGINE N2 system.
Test No. 3. Kev nyeem ntawv nyob rau hauv cov blocks loj. Emulation ntawm kev tshaj tawm xov xwm cov ntsiab lus, tsim cov ntawv ceeb toom los ntawm kev txheeb xyuas DBMS lossis rov kho cov ntaub ntawv los ntawm kev thaub qab.
Raws li nyob rau hauv qhov kev xeem dhau los, peb txaus siab rau kev ntws thiab qeeb.
- Block loj = 128k
- Nyeem / Sau = 100% / 0%
- Tus lej ua haujlwm = 16
- Qhov tob = 32
- Load Character β Sequential
streaming kev ua tau zoo yog kwv yees me ntsis zoo dua li streaming sau kev ua tau zoo.
Interestingly, qhov taw qhia latency yog zoo tib yam thoob plaws qhov kev xeem (txoj kab ncaj nraim). Qhov no tsis yog qhov yuam kev; thaum nyeem cov ntu hauv cov block loj, hauv peb rooj plaub qhov no yog qhov xwm txheej.
Tau kawg, yog tias peb tawm hauv cov kab ke hauv daim ntawv no rau ob peb lub lis piam, peb yuav pom qhov ntu ntu ntawm cov duab kos, uas yuav cuam tshuam nrog lwm yam. Tab sis, feem ntau, lawv yuav tsis cuam tshuam rau daim duab.
tshawb pom
Los ntawm dual-controller AERODISK ENGINE N2 system, peb tuaj yeem ua tiav cov txiaj ntsig loj heev (~ 438 IOPS thiab ~ 000-5 gigabytes ib ob). Load xeem tau pom tias peb yeej tsis txaj muag ntawm peb qhov system cia. Ntawm qhov tsis sib xws, cov ntsuas tau zoo heev thiab sib haum rau lub kaw lus cia zoo.
Txawm hais tias, raws li peb tau sau saum toj no, Cav N2 yog tus qauv junior, thiab ntxiv rau, cov txiaj ntsig tau qhia hauv kab lus no tsis yog nws qhov txwv. Tom qab ntawd peb yuav tshaj tawm qhov kev sim zoo sib xws los ntawm peb cov laus ENGINE N4 system.
Lawm, peb tsis tuaj yeem npog txhua qhov kev sim ua tau nyob rau hauv lub moj khaum ntawm ib tsab xov xwm, yog li peb rov hais kom cov neeg nyeem qhia lawv cov kev xav tau rau kev xeem yav tom ntej hauv cov lus; peb yuav twv yuav raug coj mus rau hauv tus account hauv kev tshaj tawm yav tom ntej.
Tsis tas li ntawd, peb nco ntsoov koj tias xyoo no peb tau koom tes nrog kev cob qhia, yog li peb caw koj mus rau peb cov chaw muaj peev xwm, qhov chaw koj tuaj yeem kawm paub txog AERODISK cov tshuab khaws cia, thiab tib lub sijhawm muaj kev txaus siab thiab lom zem.
Kuv luam tawm cov ntaub ntawv hais txog kev cob qhia yav tom ntej.
