Kubva muna Zvita 31, 2019, isu tine 124 anoshanda hard drive. Pakati peizvi, 956 ari bootable uye 2 idata. Muchidzidzo ichi, tichatarisa nhamba dzekukundikana pakati pe data hard drive. Isu tichafunga zvakare gumi nemaviri uye gumi nemana TB shanduro dze disks uye itsva 229 TB, iyo yatave tichishandisa nesimba kubva pakutanga kwekota yechina ye122.
Nhamba dze2019
Pakupera kwa2019, takatarisa 122 hard drives anoshandiswa kuchengetedza data. Takabvisa kubva kumadhiraivha ekuverenga ayo aishandiswa pakuyedza uye madhiraivha akange asina ~ 658 mazuva ekutyaira (pamuenzaniso) mukati mechikamu chechina. Saka, takaunganidza data yakavakirwa pa5 hard drives. Tafura iri pazasi inoratidza manhamba edu:
Zvinyorwa uye zvakaonekwa
151 hard drives (122 minus 658) haana kuverengerwa muhuwandu. Aya madhiraivha akashandiswa kuyedza kana kusashanda kwemazuva zviuru zvishanu zvekutyaira mukati mechikamu chechina che122. Saka, isu tinobvisa kubva kune manhamba disks ayo, mumaonero edu, haana kushanda kwenguva yakakwana kuti aite chero mhedziso.
Iyo chete inonetsa-isina dhiraivha ye2019 ndeye 4 TB Toshiba, modhi: MD04ABA400V. Uyu ndiwo mubairo wakanaka, asi sezvo takanga tine mashoma emadhiraivha aya, dai dhiraivha imwe chete yakundikana, tingadai takawana mwero we0.92%. Zvichiri zvakanaka, asi hazvisisiri 0%.
Toshiba 14 TB modhi MG07ACA14TA inoratidza mibairo yakanaka kwazvo iine 0.65% AFR uye inomira padivi pemadhiraivha anobva kuHGST. Seagate 6 TB uye 10 TB yakagadzikana pa0.96% uye 1.00%, zvichiteerana.
Iyo AFR ye2019 yemadhiraivha ese i1.89%, iyo yakanyanya kudarika ye2018. Izvi tichazokurukura gare gare.
Kupfuura nhamba - "yakavanzika" disk modhi
Mazhinji mamodheru haana kuverengerwa muhuwandu hwedu hwe2019 nekuti haana kushanda kwenguva yakakwana. Tinoda kutaura pamusoro pemhando idzi uye mashandisiro atinoita.
Seagate 16 TB
Muchikamu chechina cha2019, takatanga kukodzera Seagate 16 TB madhiraivha, modhi: ST16000NM001G. Pakupera kwekota yechina, takanga tine madhiraivha makumi mana, anomiririra mazuva e40 disco, pazasi pemazuva zviuru zvishanu zvehuwandu hwedu hwe1. Pakange pasina kukundikana pakati pemadhiraivha aya mukota yechina. Paunenge wapedza zvidzidzo zvedu, zvinozoshandiswa kune yedu gore rino.
Toshiba 8TB
MuQ4 2019 pakanga paine makumi maviri eToshiba 20 TB madhiraivha, modhi: HDWF8. Madhisiki aya akashanda kwemakore maviri. Muchikamu chechina vaingova nemazuva ekushanda kwe180, iyo iri pasi pehuwandu hwehuwandu, asi vane hupenyu hwemazuva 1 nekukundikana kwekutya kumwe chete, zvichitipa AFR ye840%. Tinoada madhiraivha aya, asi patakwanisa kuatenga muhuwandu hwataida, akatanga kuita mari inosvika gumi nemaviri TB. Kuwedzera huwandu, mutengo wakafanana. Tichifunga kuti tiri kuenda ku13TB uye madhiraivha akakura, isu tingangove tisiri kutenga madhiraivha aya mune ramangwana.
HGST 10 TB
Kune makumi maviri HGST 20 TB madhiraivha ari kushanda, modhi: HUH10ALE721010. Madhisiki aya aishandiswa kwerinopfuura gore. Ivo vari mune imwecheteyo Backblaze chengetedzo seSeagate 600TB inotyaira. Pamusoro pezvikamu zvina, madhiraivha eHGST akashanda kwemazuva 10 chete, uye kubva pakuiswa - 4 1. Paive ne840 (zero) kukundikana. Sezvakaita neToshiba 8TB, kutenga yakawanda ye042TB vhezheni hazvigoneke.
Toshiba 16TB
Iwe hauchavawana muQ2020 stats, asi muQ20 16 takawedzera makumi maviri Toshiba 08TB madhiraivha, Model: MG16ACA100TA. Vakashanda kwemazuva zana, saka zvakakurumidza kutaura nezve chero chinhu kunze kwehuwandu hwekota yekutanga ya2020.
Kuenzaniswa kweiyo hard drive statistics ye2017, 2018 uye 2019.
Tafura iri pazasi inofananidza mwero wepagore wekutadza (AFR) kune rimwe nerimwe remakore matatu apfuura:
AFR kukura muna 2019
Iyo AFR yese ye2019 yakawedzera zvakanyanya. AFR yakawedzera 75% yemamodheru kubva 2018 kusvika 2019. Pane zvinhu zviviri zvikuru zviri seri kwekukura uku. Chekutanga, iyo yese mutsara we8 TB inotyaira inosangana ne "midlife dambudziko" sezvavanoshandiswa. Iwo epamusoro maAFR anoratidzwa nemadhiraivha anosanganisirwa muboka re8 TB. Pasinei neiyo AFR yakakwirira, hapana chikonzero chekunetseka zvakanyanya. Ichokwadi ndechokuti ma disks aya akashanda 1/4 yemazuva ehuwandu hwedu hwose uye kuchinja kuduku kunogona kuvakanganisa. Chechipiri cheSeagate 12 TB madhiraivha, dambudziko iri riri kugadziriswa mukati meprojekti , iyo yakamboshumwa.
Kutama kuri kunonoka, asi kukura hakusi
Muna 2019, takawedzera 17 madhiraivha matsva. Muna 729, mazhinji e2018 madhiraivha akawedzerwa akashandiswa sechikamu chekutama. Muna 14, isingasviki hafu yemadhiraivha matsva akagadzirirwa kutama, mamwe ese achishandiswa kune matsva masisitimu. Muna 255, takasiya 2019 madhiraivha ehuwandu hwemapetabytes makumi matatu nemanomwe tikaatsiva ne2019 madhiraivha, ese gumi nemaviri TB, angangoita zana negumi neshanu petabytes, uyezve muna 8 takawedzera mamwe 800 petabytes ekuchengetedza tichishandisa mavhoriyamu e37 ne8 TB.
Zvakasiyana-siyana
Iwo akasiyana evagadziri nedhiraivha brand akawedzera zvishoma muna 2019. Muna 2018, madhiraivha eSeagate akagadzira 78,15% yemadhiraivha, uye pakupera kwa2019, nhamba iyi yakadzikira kusvika 73,28%. HGST yakawedzera kubva pa20,77% muna 2018 kusvika pa23,69% muna 2019, uye Toshiba kubva pa1,34% muna 2018 kusvika pa3,03% muna 2019. Pakanga pasina madhiraivha ane zita reWestern Digital munzvimbo yedata muna 2019. sezvo WDC yanga ichiburitsa HGST itsva.
Huwandu hwehupenyu hwebasa
Tichiri kuenzanisa gore rega rega hard drive kutadza mitengo mumakore akati wandei inzira huru yekuziva mafambiro, isu tinotarisawo kutadza kwepagore kwemadhiraivha edu akaomarara muhupenyu hwavo. Chati iri pazasi inoratidza mwero wepagore wekutadza kweese madhiraivha emhando mukugadzirwa kubva muna Zvita 31, 2019:
