Aliyense amavomereza kuti kuwala kungapereke ntchito yapadera. Ndipo pazinthu zina ndi ntchito, ntchito yotereyi ndi yofunika kwambiri. Mwachitsanzo, pamene olemba akugwira ntchito ndi mitsinje yambiri ya 4K (kapena kawirikawiri, kanema ya 8K), kuwunikira kungapereke mtundu wa zochitika zomwe zimafunikira kuti zikhale zovuta kwambiri.

Komabe, pali chikhulupiliro chachikulu mu makampani opanga mafilimu ndi zosangalatsa omwe amawunikira luso lamakono ndi lamtengo wapatali. Liti Quantum owonetsa mavidiyo ojambula - kuyambira kumalo osungirako ntchito, mabungwe ofalitsa, mabungwe opanga makina, ma studio ndi makampani operekera ku North America, Europe ndi Asia - oposa theka la anthu omwe anafunsidwawo adatchula mtengo wotsika mtengo chifukwa chokhazikitsa njira yothetsera magetsi.

Uwu ndi choonadi chokha, ndipo chimodzi chomwe chimangonena theka la nkhaniyo. Ndalama ya njira yosungirako yosungirako zonse idzawoneka yotsika kwambiri pamene kusanthula kumangoganizira za mtengo wofanana ndi mphamvu ($ / TB) yokhudzana ndi HDD ndi njira zothandizira SSD. Komabe, pamene mtengo wonse wa umwini (TCO) wapangidwira, osatchula kuwonjezeka kwa ntchito, ndalama za kusungirako zida, ndi makamaka yosungirako zolemba (NVMe) flash yosungirako, zimakakamiza.

Zinthu zoyamba choyamba - Kodi NVMe ndi chiyani?

Mpaka kukhazikitsidwa kwa NVMe, yosungirako mafilimu ambiri - monga magetsi olimba (SSDs) - kugwiritsa ntchito matebulo a SATA kapena SAS kuti agwirizanitse zosungirako ndi ma kompyuta ena onse. Koma SATA ndi SAS poyamba zinalinganizidwa kuti zithandize ma disk hard disk (HDDs), ndipo monga opanga amapanga magalimoto atsopano, ofulumira kwambiri, ma teknoloje akalewa amalephera kugwira ntchito kwa SSDs.

NVMe idapangidwa mwachindunji kusungirako komweko. Ndi NVMe, phokoso lililonse la CPU limalumikizana ndi yosungirako pogwiritsa ntchito basi yapamwamba ya PCI m'malo mmalo ochepa a SATA kapena SAS. Pogwiritsira ntchito PCIe, ma drive omwe amawunikira amagwiritsa ntchito ndi malingaliro m'malo mwa ma HDD. NVMe ikukwaniritsa ntchito yapamwamba pambali pothandizira malamulo ambiri pamlingo, komanso njira zopankhulirana, kuposa ma protocol a SATA kapena SAS. SATA ndi SAS iliyonse ili ndi ma queue amodzi, omwe angagwiritse ntchito ku 32 ndi 254 malamulo, motsatira. Mosiyana ndi, NVMe ikhoza kuthandizira pafupi ndi ma 65,000 mizere ndi malamulo a 65,000 pamzerewu.

Poyerekeza ndi SATA ndi SAS, NVMe imathandiza kwambiri zopempha zowerengedwa mofulumira. NVM tikhoza kuwerengera pafupifupi 1 milioni yowerengeka pamphindi, poyerekeza ndi SATA pafupi ndi 50,000 ndi SAS pa pafupifupi 200,000 yowerenga mwachindunji pamphindi. Ndipo, ngakhale ndi zonse zomwe zimawerengedwa, NVMe imapitiriza latency pansi pa 20 microseconds, poyerekeza ndi pansi pa 500 microseconds kwa SATA ndi SAS. Kwa iwo

pogwiritsa ntchito yosungirako kuthandizira makasitomala ambiri omwe akufuna mitsinje yofanana ya deta, SSDs imatulutsa kwambiri HDDs.

NVMe ikhoza kuperekanso kudutsa kokhazikika pa intaneti. Kuyesedwa mkati ndi Quantum, NVMsungidwe imapezeka kuti imapereka nthawi zoposa 10 kuwerenga ndi kulemba machitidwe opatsirana ndi kasitomala amodzi poyerekeza ndi makasitomala a NFS ndi SMB.

TCO yokakamiza

NVMe ndi teknoloji yofewa yomwe imalola ogwiritsa ntchito kuti asatsegule zenizeni zenizeni za flash, koma kuti achite zimenezo pamene akuchepetsa TCO. Phindu la malamulo ambiri pamphindi, kuwerenga mofulumira, kuchepa kwa latency komanso kupambana kwapadera kumagwirizanitsa ndikupangitsa NVMe kupereka ndalama zowonongeka komanso zopindulitsa.

M'mbuyomu, kugwiritsira ntchito phokoso la kusungirako katundu kunagwiritsidwa ntchito koletsedwa chifukwa mabungwe omwe amagwiritsa ntchito kwambiri Fiber Channel akugwirizana. Kugwiritsa ntchito Intaneti kumakhala ndalama zambiri zachiwiri pambuyo pa zosungiramo zosungirako, ndipo Fiber Channel kulumikiza ikhoza kukhala katatu kapena kanayi mtengo kuposa Ethernet.

Ndi NVMe, mabungwe akhoza kupeza Fiber Channel-monga ntchito pogwiritsa ntchito zambiri zamtengo wapatali teknolojia Ethernet. Teknoloji ya Ethernet imalola ogwiritsira ntchito kusunga ndalama osati pa zipangizo komanso pa kasamalidwe, popeza kulamulira kwa Ethernet sikufuna luso lapadera la kukonza Fiber Channel. Malingana ndi kukula kwa bungwe, pali mwayi wopulumutsa makumi masauzande - kapena ngakhale masauzande - madola pa intaneti pogwiritsira ntchito Ethernet.

Zosungirako zokhazo zimangowonongetsa ndalama mu NVMe yosungirako.

Poganizira NVMe, sikuyenera kukhala zonse kapena ayi

Pamene anthu amaganiza za NVMe, nthawi zambiri amawoneka ngati wakuda ndi woyera - onse a NVMe kapena ayi. Koma pali malo aakulu ammunsi omwe ayenera kufufuzidwa. Injini imene imayendetsa nsanja iliyonse yapamwamba yamagetsi ndi mapulogalamu. Kugwiritsira ntchito NVMe yosungirako ndi mawonekedwe amakono a mafayilo ndi deta yosamalira deta akhoza kupereka malo ambiri osungirako zinthu ndi malo amodzi, omwe ali ndi mayina padziko lonse. Mabungwe akhoza kugula kokha kuchuluka kwa NVMe yosungirako yofunikira pa ntchito zina pamene akugwiritsa ntchito njira zina zosungirako komanso - kuphatikizapo ma disk-based arrays, makanema a matepi, ndi kusungirako mitambo - ntchito zomwe sizifuna mlingo womwewo wa ntchito. Kukhoza kumapanga malo osungirako osakanizidwa kumapangitsa mabungwe kuchepetsa kugula kwawo kwasungirako kowonjezera, pamene akusangalala nawo phindu lawo lonse.

Onetsetsani, osati kutengeka

Ndi 4K tsopano yofala ndipo 8K mwamsanga kukhala yatsopano, masomphenya pang'ono ndi kukonzekera lero adzakolola ndalama zazikulu mtsogolomu. Zosungirako zosungirako zomwe zimakhala zochepa zimapereka mphamvu zothandizira maonekedwe a 4K lero, komanso za mtsogolo kuphatikizapo

8K ndi kupitirira. Mabungwe omwe amachititsa zipangizo zamakono kuti azigwiritsira ntchito maluso awo osungirako zidzakhala bwino kuti azigwira ntchito ndi makompyuta a NVMe omwe alipo komanso atsopano. Ndipo pamene moyo wautumiki wa machitidwewa ukufutukulidwa, ndalama zowonongeka zidzachepetse - kupanga ndalamazo kupita patsogolo kwambiri.

Kwa mabungwe omwe ali ndi malipiro ochepa kapena olepheretsa kugulitsa ndi kuwunikira chifukwa cha mtengo wapamwamba woganizira kusungirako magetsi, ndikufunsa mafunso otsatirawa:

• Kodi kusanthula mtengo kwa ndalama kumagwiritsa ntchito ndalama zothandizira deta, ndalama zogwirira ntchito, ndalama zowonongeka, komanso ndalama zogwiritsira ntchito malonda poyerekeza ndi dongosolo la HDD?

• Kodi mtengo ulipira chiyani pa ntchito pa kasitomala, osati mphamvu?

Kufufuza mafunsowa mwakuya kungakupangitseni kupeza kuti kutumiza NVMe ndi yankho - osati ngakhale mtengo, koma chifukwa cha izo. Nthawi zina choonadi chimakhala mwatsatanetsatane.
