I-SMR (i-tiled) ii-hard drives ngaphandle kokubonisa ubukho be-SMR baye kwiindlela zokuthengisa

Bobathathu abavelisi baqale ukuthengisa ezincinci, ukuqala kwi-2TB HDD Iidiski zeSMR (zifakwe iithayile)ngaphandle kokuyichaza kwiinkcukacha: WD, Seagate, Toshiba

Kwi-Intanethi yolwimi lwesiNgesi kunye namajelo eendaba, ezo zenzo ziyagxekwa kwaye, ndicinga ukuba kunjalo. E-Russia, isibonelelo se-THG saphawulwa ngenqaku I-Western Digital isebenzisa i-DM-SMR, yenza i-WD Red drives efanelekileyo kwi-NAS kunye ne-RAID. Eli nqaku, ngokombono wam, ubuxoki obungenazintloni, ukusuka kwisihloko ukuya kwisigqibo: "Siyabonga kwi-DM-SMR iteknoloji yokurekhoda, i-Western Digital yenze i-WD yayo ebomvu i-hard drives efanelekileyo kwi-NAS kunye ne-RAID." Kuyathakazelisa ukuba kwinguqulelo yesiNgesi yenqaku I-Western Digital Fesses Up: Ezinye ii-HDD eziBomvu zisebenzisa i-Slow SMR Tech ngaphandle kokuchaza
akukho ntelekelelo yokugqwethwa kwezibakala

Kwakhona kwisicatshulwa thg.ru ibhekisa kuAlan Brown,

U-Alan Brown, umlawuli wenethiwekhi kwi-UCL Mullard Space Science Laboratory, ufumene indlela yokuphuma kule meko. Wafumanisa ukuba i-RAID yokulahla, eyenziwa xa idibanisa i-drive entsha kuluhlu olukhoyo lwe-RAID kwaye emva koko ibhala ngaphezulu kwi-balance access, ibangele ukuba inkqubo ithathe ii-WD ezibomvu ze-HDD ngaphandle kolawulo.

Akucacanga ukuba ithetha ukuthini kanye kanye ukuba "inkqubo isusa ii-WD Red HDDs ezintsha phantsi kolawulo lwayo." - kodwa ngokwentsingiselo yesindululo, esi sisisombululo.

Kwangelo xesha U-Alan ngokwenene wabhala ngesihloko - kodwa ngokuchaseneyo

I-WD40EFAX drive endiyigcwalise ngo-zero i-avareji ye-40MB/s, kodwa iqale ku-120MB/s.

Kwimeko ye-ZFS, isisombululi ayisosiphelo-kwinqanaba lokuskena lebhloko, kodwa litsibela ngapha kwediski yonke njengoko ifayile nganye ibuyiselwa kumlinganiso. Oku kubonakala kubangele omnye umba kwi WD40EFAX, apho isicelo sokukhangela icandelo elingekabhalwa libangela ukuba uqhubo luloge ngaphakathi ngaphakathi impazamo ye "ID yeCandelo ayifunyenwanga (IDNF)" kwaye ujule impazamo yehardware ye/O ukusuka. ujongano kwindlela yokusingatha.

Abalawuli be-RAID (i-hardware okanye isoftware, i-RAID5/6 okanye i-ZFS) baya kwenza isigqibo esifanelekileyo sokuba i-drive imbi emva kokumbalwa kubo kwaye bayikhuphe kuluhlu ukuba ayikabikho emva kokuphela kwexesha.

Oku ngokuqinisekileyo kuhambelana nento endiyibonileyo - umamkeli uhamba malunga ne-100MB / s malunga nemizuzu engama-40, emva koko i-drives "ifa" kwaye ifa ngokuphindaphindiweyo ukuba ndizama ukuqala kwakhona umamkeli, nangona kunjalo, ukuba ndiyishiya - emva kweyure okanye njalo. , basebenza eminye imizuzu engama-40 ngaphambi kokuba bawe.

Kunzima ukucinga ukuba yintoni kanye kanye eyenza i-thg.ru yenze oku. Umntu unokuthelekelela nje ukuba oku bekubangelwa luxinzelelo lwabathengisi. Nakweyiphi na imeko, imeko xa iidrive ezithandwayo ezijolise ngokukodwa kwi-NAS zithe cwaka zitshintshwa ngokuphawulekayo ezingafanelanga kakhulu ngexabiso elifanayo kwaye ngaphandle kokutshintsha iinkcukacha zifuna ukuhoywa.

Kwinkomfa Kwakukho ukukhankanywa kwengxaki kwiwebhusayithi yeWD. Undoqo uyafana

Ndisandula kuthenga ii-3 WD REDs ukuze ndithathe indawo ye-aging drives kuluhlu lwe-ZFS

BONKE ABATHATHU bayasilela ngexesha lokuguqulwa kwe-IDNF (i-ID yecandelo ayifumaneki) iimpazamo:

Ngokokuqonda kwam, ingxaki ikwi
I-WD RED - I-WD Ebomvu EFAX zii-SMR drives kwaye zine-256 MB ye-cache. EFRX drives - musa ukusebenzisa SMR (ezi CMR rhoqo drives) kwaye babe 64 MB cache
UToshiba unemizekelo emininzi iinkcukacha ezininzi apha
I-Seagate inothotho oluninzi- iinkcukacha ezininzi apha
