SMR (tiled) hard drives pasina kuratidza kuvapo kweSMR yakapinda mukutengesa nzira

Vese vagadziri vatatu vakatanga kutengesa zvidiki, kutanga kubva ku2TB HDD SMR disks (akaiswa mataira)pasina kuzvitsanangura mune zvakatemwa: WD, Seagate, Toshiba

PaInternet-mutauro weChirungu uye midhiya, zviito zvakadaro zvinoshorwa uye, ndinofunga, ndizvozvo. MuRussia, iyo THG sosi yakacherechedzwa nechinyorwa Western Digital inoshandisa DM-SMR, ichiita WD Red madhiraivha akakodzera NAS uye RAID. Ichi chinyorwa, mumaonero angu, manyepo asinganyari, kubva pazita kusvika kumagumo: "Tinotenda kuDM-SMR tekinoroji yekurekodha, Western Digital yakaita madhiraivha ayo eWD Red akakodzera NAS neRAID." Zvinonakidza kuti muChirungu chinyorwa chechinyorwa Western Digital Fesses Up: Mamwe maRed HDD Anoshandisa Inononoka SMR Tech Pasina Kuburitswa
hapana chinoratidza kukanganisa kwakadaro kwechokwadi

Zvakare muzvinyorwa thg.ru zvinoreva Alan Brown,

Alan Brown, network maneja paUCL Mullard Space Science Laboratory, akawana nzira yekubuda mumamiriro ezvinhu aya. Akaona kuti marasirwo eRAID, ayo anoitwa kana achiwedzera dhiraivha kune iripo RAID array obva ainyora pasi kuti aenzanise kuwana, zvakaita kuti sisitimu itore maWD Red HDDs kubva pakutonga.

Hazvina kujeka kuti zvinorevei chaizvo "system inobvisa maWD Red HDDs matsva kubva pasi pesimba rayo." - asi maererano nechirevo chechikumbiro, iyi ndiyo mhinduro.

Panguva imwecheteyo Alan akanyora chaizvo pamusoro penyaya - asi zvakapesana

Iyo WD40EFAX drive yandakazadza ne zero avhareji 40MB/s, asi yakatanga pa120MB/s.

Panyaya yeZFS, mugadzirisi hausi wekupedzisira-kusvika-kumagumo block-level scan, asi inosvetukira mukati medhisiki rese sezvo faira rega rega richidzoserwa parimwe. Izvi zvinoita sekunge zvichikonzera imwe nyaya paWD40EFAX, uko chikumbiro chekutarisa chikamu chisati chanyorwa kuti chiite kuti drive ipinde mukati mukati me "Sector ID Haina Kuwanikwa (IDNF)" kukanganisa uye kukanda hardware I/O kukanganisa kubva. interface kune iyo host system.

RAID controllers (hardware kana software, RAID5/6 kana ZFS) inonyatso funga zvine musoro kuti dhiraivha yakashata mushure mevashoma vavo voibvisa kubva muhurongwa kana isati yatopedza nguva.

Izvi zvechokwadi zvinoenderana nezvandakaona - mugamuchiri anoenda kunenge 100MB / s kweanenge maminetsi makumi mana, mushure mezvo madhiraivha "anofa" uye anofa kakawanda kana ndikaedza kutangazve anogamuchira, zvisinei, kana ndikasiya - mushure meawa kana zvakadaro. , vanoshanda kwemamwe maminitsi makumi mana vasati vadonha.

Zvakaoma kufungidzira kuti chii chaizvo chakaita kuti thg.ru iite izvi. Munhu anogona kungofungidzira kana izvi zvakakonzerwa nekumanikidzwa nevashambadziri. Chero zvazvingava, mamiriro ezvinhu apo madhiraivha akakurumbira akagadzirirwa zvakananga kuNAS anotsiviwa chinyararire neakanyanya kushomeka akakodzera pamutengo mumwe chete uye pasina kushandura zvakatemwa zvakakodzera kutariswa.

Pamusangano Pane kutaurwa kwedambudziko pawebhusaiti yeWD. Hunhu hwakafanana

Ndichangobva kutenga 3 WD REDs kuti nditsive madhiraivha ekuchembera muZFS array

VESE VATATU vari kutadza panguva yekudzoreredzwa neIDNF (sector ID haina kuwanikwa) zvikanganiso:

Sekunzwisisa kwangu, dambudziko riripo
WD RED - WD Tsvuku EFAX madhiraivha eSMR uye ane 256 MB yecache. EFRX madhiraivha - usashandise SMR (aya anowanzo CMR madhiraivha) uye ane 64 MB cache.
Toshiba ine mhando dzakawanda zvimwe pano
Seagate ine akati wandei akateedzana - zvimwe pano
