Ma hard drive a SMR (matayala) osawonetsa kupezeka kwa SMR adalowa munjira zogulitsa

Opanga onse atatu adayamba kugulitsa ang'onoang'ono, kuyambira 2TB HDD Ma disks a SMR (opangidwa ndi matailosi)popanda kufotokoza mwatsatanetsatane: WD, Seagate, Toshiba

Pa intaneti ya chilankhulo cha Chingerezi ndi media, izi zimatsutsidwa ndipo, ndikuganiza, zili choncho. Ku Russia, gwero la THG lidadziwika ndi nkhani Western Digital imagwiritsa ntchito DM-SMR, kupanga ma drive a WD Red oyenera NAS ndi RAID. Nkhaniyi, mwa lingaliro langa, ndi bodza lopanda manyazi, kuyambira pamutu mpaka kumapeto: "Chifukwa cha teknoloji yojambulira DM-SMR, Western Digital yapanga ma hard drive ake a WD Red oyenera NAS ndi RAID." Ndizosangalatsa kuti mu Chingerezi cha nkhaniyi Western Digital Fesses Up: Ma HDD Ena Ofiira Amagwiritsa Ntchito Slow SMR Tech Popanda Kuwululidwa
palibe lingaliro la kupotozedwa kwa mfundo koteroko

Komanso m'mawu akuti thg.ru akunena za Alan Brown,

Alan Brown, woyang'anira maukonde ku UCL Mullard Space Science Laboratory, adapeza njira yothetsera vutoli. Anapeza kuti kutaya kwa RAID, komwe kumachitika pamene galimoto yatsopano ikuwonjezeredwa ku gulu la RAID lomwe liripo kenako ndikulembedwanso kuti lipezeke bwino, zinachititsa kuti dongosololi lichotse ma WD Red HDD atsopano.

Sizikudziwika kuti kwenikweni zikutanthauza chiyani "dongosolo limachotsa ma WD Red HDD atsopano pansi pa ulamuliro wake." - koma malinga ndi tanthauzo la lingalirolo, ili ndiye yankho.

Nthawi yomweyo Alan analembadi pa mutuwo - koma mosiyana

Magalimoto a WD40EFAX omwe ndidadzaza ndi ziro pafupifupi 40MB/s, koma adayamba pa 120MB/s.

Pankhani ya ZFS, chosinthira sichojambula chomaliza mpaka kumapeto, koma chimadumphira pa disk yonse pomwe fayilo iliyonse imabwezeretsedwanso. Izi zikuwoneka kuti zikuyambitsa vuto lina pa WD40EFAX, pomwe pempho loyang'ana gawo lomwe silinalembedwe limapangitsa kuti galimotoyo ilowe mkati cholakwika cha "Sector ID Not Found (IDNF)" ndikuponya cholakwika cha I/O cha hardware kuchokera. mawonekedwe ku host host.

Olamulira a RAID (hardware kapena software, RAID5/6 kapena ZFS) angaganize momveka bwino kuti galimotoyo ndi yoyipa pambuyo pa ochepa a iwo ndikuichotsa pamndandanda ngati isanathe.

Izi zikufanana ndi zomwe ndazindikira - wolandila amapita pafupifupi 100MB / s kwa mphindi pafupifupi 40, kenako amayendetsa "Die" ndikufa mobwerezabwereza ngati ndiyesera kuyambiranso wolandila, ndikasiya - patatha ola limodzi kapena apo. , amagwira ntchito kwa mphindi 40 asanagwe.

Ndizovuta kulingalira chomwe chinapangitsa thg.ru kuchita izi. Munthu angangolingalira ngati izi zinali chifukwa cha kukakamizidwa ndi otsatsa. Mulimonse momwe zingakhalire, pomwe ma drive odziwika omwe amapangidwira makamaka NAS amasinthidwa mwakachetechete ndi ocheperako pamtengo womwewo ndipo osasintha zomwe akuyenera kuziganizira.

Pamsonkhanowo Panali kutchulidwa zavuto patsamba la WD. Mfundo yake ndi yofanana

Ndangogula 3 WD REDs kuti ndisinthe ma drive okalamba mumagulu a ZFS

ONSE ATATU akulephera pakukonzanso zolakwika za IDNF (ID ya gawo silinapezeke):

Momwe ndikumvera, vuto ndi
WD RED - WD Red EFAX ndi ma drive a SMR ndipo ali ndi 256 MB ya cache. Ma drive a EFRX - osagwiritsa ntchito SMR (awa ndi ma drive okhazikika a CMR) ndipo ali ndi cache ya 64 MB
Toshiba ali ndi zitsanzo zingapo zambiri apa
Seagate ili ndi mndandanda wambiri - zambiri apa
