Sanibonani nonke! Njengoba sithembisile, sishicilela imiphumela yokuhlolwa komthwalo wesistimu yokugcina idatha eyenziwe eRussia - I-AERODISK ENGINE N2.
Esihlokweni esandulele, siphule isistimu yokugcina (okungukuthi, senze izivivinyo zokuphahlazeka) futhi imiphumela yokuhlolwa kokuphahlazeka yayivuma (okungukuthi, asizange siphule isistimu yokugcina). Ungabuka imiphumela yokuhlolwa kokuphahlazeka .
Kumazwana esihlokweni esedlule, izicelo zenziwe zokuhlolwa kokuphahlazeka okwengeziwe, okuyinkimbinkimbi. Siziqophe zonke futhi sizozisebenzisa nakanjani kwesinye sezindatshana ezilandelayo. Ngasikhathi sinye, ungavakashela ilabhorethri yethu eMoscow nganoma yisiphi isikhathi (woza ngezinyawo noma ukwenze ukude nge-Intanethi) futhi wenze lezi zivivinyo ngokwakho (ungenza ngisho nokuhlola iphrojekthi ethile :-)). Sibhalele, sizocubungula zonke izimo!
Ngaphezu kwalokho, uma ungekho e-Moscow, usengakwazi ukujwayelana nesistimu yethu yokugcina izinto ngokuya emcimbini wokuqeqeshwa wamahhala esikhungweni samakhono edolobheni eliseduze nawe.
Ngezansi kunohlu lwemicimbi ezayo nezinsuku zokusebenza zezikhungo zamakhono.

Sifuna futhi ukwabelana ngezindaba ezimnandi: ekugcineni sizitholile ezethu isiteshi lapho ungabuka khona amavidiyo emicimbini edlule. Sihlala sithumela amavidiyo ethu okuqeqesha lapho.
Isitendi sokuhlola
Ngakho-ke, buyela ekuhlolweni. Sithuthukise isistimu yethu yokugcina ilabhorethri ye-ENGINE N2 ngokufaka amadrayivu engeziwe e-SAS SSD, kanye nama-adaptha e-Front-end Fiber Channel 16G. Ngendlela elinganayo, sithuthukise iseva esizosebenzisa kuyo ukulayisha ngokungeza ama-adaptha e-FC 16G.
Ngenxa yalokho, elebhu yethu sinesistimu yokugcina izilawuli ezi-2 ezinamadiski angu-24 SAS SSD 1,6 TB, 3 DWPD disks, axhunywe ngokushintsha kwe-SAN kuseva ye-Linux ebonakalayo nge-FC 16G.
Umdwebo webhentshi lokuhlola uboniswa emfanekisweni ongezansi.
Indlela yokuhlola
Ukuze sisebenze kahle kakhulu ekufinyeleleni ibhulokhi, sizosebenzisa amachibi e-DDP (Dynamic Disk Pool), esake sawadalela ngokukhethekile amasistimu e-ALL-FLASH.
Ukuze kuhlolwe, sidale ama-LUN amabili anomthamo ongu-1 TB ngalinye elineleveli yokuvikela ye-RAID-10. "Sizosabalalisa" i-LUN ngayinye kumadiski angu-12 (24 esewonke) ukuze sisebenzise ngokugcwele amandla ediski ngayinye efakiwe ohlelweni lokugcina.
Sethula ama-LUN kuseva ngokusebenzisa izilawuli ezihlukene ukuze sisebenzise izinsiza zokulondoloza ngangokunokwenzeka.
Ukuhlola ngakunye kuzohlala ihora elilodwa, futhi ukuhlolwa kuzokwenziwa uhlelo lwe-Flexible IO (FIO); idatha ye-FIO izolayishwa ngokuzenzakalelayo ku-Excel, lapho amagrafu asevele akhelwe ukucaca.
Layisha Amaphrofayili
Sekukonke, sizokwenza izivivinyo ezintathu, ihora elilodwa ngakunye, singafaki isikhathi sokufudumala, esizokwabela sona imizuzu eyi-15 (lokhu kuyimalini edingekayo ukufudumala uxhaxha lwama-SSD angama-24). Lezi zivivinyo zilingisa amaphrofayili okulayisha okuvame ukuhlangana nawo, ikakhulukazi lawa ama-DBMS athile, amasistimu okuqapha amavidiyo, ukusakazwa kokuqukethwe kwemidiya nezipele.
Futhi, kukho konke ukuhlola, sikhubaze ngamabomu amandla okufaka kunqolobane ku-RAM kusistimu yokugcina kanye nakusokhaya. Yiqiniso, lokhu kuzolimaza imiphumela, kodwa, ngokombono wethu, ezimweni ezinjalo ukuhlolwa kuzoba kuhle kakhulu.
Imiphumela yokuhlola
Inombolo yokuhlola 1. Ukulayisha okungahleliwe ngamabhulokhi amancane. Ukulingiswa kwe-DBMS yokuthenga enomthwalo ophezulu.
- Usayizi wokuvimba = 4k
- Funda/Bhala = 70%/30%
- Inani lemisebenzi = 16
- Ukujula komugqa = 32
- Layisha uhlamvu = Okungahleliwe Okugcwele
Imiphumela yokuhlolwa:
Sekukonke, ngohlelo oluncane lwe-Mid-range Engine N2 sithole i-438k IOPS nge-latency yama-millisecond angu-2,6. Ngokucabangela isigaba sohlelo, ngokombono wethu, umphumela muhle impela. Ukuze siqonde ukuthi ingabe lokhu kuwumkhawulo wesistimu, sizobheka ukusetshenziswa kwensiza yezilawuli zesitoreji.
Sinentshisekelo ngokuyinhloko ku-CPU, njengoba, njengoba kushiwo ngenhla, sikhubaze ngamabomu inqolobane ye-RAM ukuze singahlanekezeli imiphumela yokuhlolwa.
Kuzo zombili izilawuli zesitoreji sibona cishe isithombe esifanayo.
Okusho ukuthi, umthwalo we-CPU ungama-50%. Lokhu kuphakamisa ukuthi lokhu kukude nomkhawulo walesi simiso sesitoreji futhi sisengalinganiswa kalula. Masiqhubekele phambili kancane: zonke izivivinyo ezilandelayo ziphinde zabonisa umthwalo kumaphrosesa wesilawuli ukuthi ucishe ube ngu-50%, ngakho-ke ngeke siwafake kuhlu futhi.
Ngokusekelwe ekuhlolweni kwethu kwaselabhorethri, umkhawulo onethezekile wesistimu ye-AERODISK Engine N2, uma sibala i-IOPS engahleliwe kumabhulokhi angu-4k, ngu-~700 IOPS. Uma lokhu kungenele futhi udinga ukulwela isigidi, khona-ke sinemodeli endala ENGINE N000.
Okusho ukuthi, indaba emayelana nezigidi ze-IOPS ithi ENGINE N4, futhi uma isigidi singaphezu kwakho, sebenzisa i-N2 ngomoya ophansi.
Ake sibuyele emivivinyweni.
Isivivinyo No. 2. Ukurekhoda okulandelanayo kumabhulokhi amakhulu. Ukulingiswa kwezinhlelo zokubhekwa kwevidiyo, ukulayisha idatha ku-DBMS yokuhlaziya noma ukurekhoda amakhophi ayisipele.
Kulesi sivivinyo asisenayo intshisekelo ku-IOPS, njengoba uma ilayishwa ngokulandelana kumabhulokhi amakhulu awawenzi umqondo. Sinentshisekelo ngokuyinhloko: ukugeleza kokubhala (ama-megabytes ngomzuzwana) nokulibaziseka, okuyiqiniso, okuzoba phezulu ngamabhulokhi amakhulu kunamancane.
- Usayizi wokuvimba = 128k
- Funda/Bhala = 0%/100%
- Inani lemisebenzi = 16
- Ukujula komugqa = 32
- Layisha Uhlamvu - Okulandelanayo
Ingqikithi: sinokurekhodwa kwamagigabhayithi amahlanu nohhafu ngomzuzwana nokulibaziseka kwamamillisecond ayishumi nanye. Uma kuqhathaniswa nezimbangi zayo zangaphandle eziseduze, umphumela, ngokubona kwethu, muhle kakhulu, futhi awuwona umkhawulo wesistimu ye-ENGINE N2.
Isivivinyo No. 3. Ukufunda ngokulandelana emabhuloki amakhulu. Ukulingisa okuqukethwe kwemidiya yokusakaza, ukukhiqiza imibiko evela ku-DBMS yokuhlaziya noma ukubuyisela idatha evela kuzipele.
Njengasekuhlolweni kwangaphambilini, sinentshisekelo ekugelezeni nasekubambezelekeni.
- Usayizi wokuvimba = 128k
- Funda/Bhala = 100%/0%
- Inani lemisebenzi = 16
- Ukujula komugqa = 32
- Layisha Uhlamvu - Okulandelanayo
Ukusebenza kokufunda kokusakaza-bukhoma kuhle kakhulu kunokubikezela kokubhala kokusakaza-bukhoma.
Kuyathakazelisa ukuthi inkomba yokubambezeleka iyafana kulo lonke isivivinyo (umugqa oqondile). Lokhu akulona iphutha; lapho ufunda ngokulandelana kumabhulokhi amakhulu, esimweni sethu lesi yisimo esivamile.
Yiqiniso, uma sishiya uhlelo kuleli fomu amasonto ambalwa, ekugcineni sizobona ukweqa ngezikhathi ezithile kumagrafu, okuzohlotshaniswa nezici zangaphandle. Kodwa, ngokuvamile, ngeke zithinte isithombe.
okutholakele
Kusuka ohlelweni lwe-dual-controller AERODISK ENGINE N2, sikwazile ukuzuza imiphumela ebucayi (~438 IOPS kanye ~000-5 gigabytes ngomzuzwana). Ukuhlolwa komthwalo kubonise ukuthi asinamahloni ngempela ngesistimu yethu yokugcina izinto. Ngokuphambene nalokho, izinkomba zihloniphekile futhi zihambisana nohlelo oluhle lokugcina.
Nakuba, njengoba sibhale ngenhla, Engine N2 - imodeli junior, futhi ngaphandle kwalokho, imiphumela eboniswe kulesi sihloko akuyona umkhawulo. Kamuva sizoshicilela ukuhlolwa okufanayo ohlelweni lwethu oludala lwe-ENGINE N4.
Ngokwemvelo, asikwazi ukumboza zonke izivivinyo ezingaba khona ngaphakathi kohlaka lwendatshana eyodwa, ngakho-ke siphinda sinxusa abafundi ukuthi babelane ngezifiso zabo ngokuhlolwa okuzayo kumazwana; sizozicabangela nakanjani ezincwadini ezizayo.
Ngaphezu kwalokho, sikukhumbuza ukuthi kulo nyaka sihlanganyela ngenkuthalo ekuqeqesheni, ngakho-ke sikumema ezikhungweni zethu zamakhono, lapho ungathola khona ukuqeqeshwa ezinhlelweni zokugcina ze-AERODISK, futhi ngesikhathi esifanayo ube nesikhathi esithakazelisayo nesijabulisayo.
Ngiphinda ulwazi mayelana nemicimbi yokuqeqeshwa ezayo.
