I. Selelekela
Lefats'eng la polokelo ea data, ho khetha theknoloji e nepahetseng ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso. Likhetho tse peli tse atileng haholo komporong ea sejoale-joale ke PCIe (Peripheral Component Interconnect Express) le NVMe (Non-Volatile Memory Express). Ho utloisisa liphapang tsa bona ho bohlokoa bakeng sa ho khetha tharollo e nepahetseng, ebang u ntlafatsa PC ea papali, ho haha setsi sa mosebetsi, kapa ho ntlafatsa seva.
A. Overview of Storage Technologies
Tlhokahalo ea polokelo e potlakileng le e tšepahalang e ntse e hola ha lits'ebetso tse joalo ka lipapali, ho hlophisoa ha video, le ts'ebetso e kholo ea data li hloka lebelo le holimo le ho lieha ho tlase. Mekhoa ea setso ea ho boloka e kang Li-HDD (Hard Disk Drives) esita le SATA SSDs (Solid-State Drives) ha e sa khona ho tsamaisana le litlhoko tsa ts'ebetso ea mesebetsi ea sejoale-joale.
PCIe ke maemo a sebopeho se nolofalletsang puisano e potlakileng lipakeng tsa likarolo tse kang CPU le lisebelisoa tsa polokelo.
NVMe, ka lehlakoreng le leng, ke protocol e hahiloeng ka ho khetheha bakeng sa li-drive-state drives (SSDs), e etselitsoeng ho phahamisa lebelo la polokelo ea flash ea morao-rao.
2. PCIe (Peripheral Component Interconnect Express) ke eng?
PCIe (Peripheral Component Interconnect Express) ke sehokelo sa lebelo le holimo se nolofalletsang puisano lipakeng tsa CPU, memori le lisebelisoa tse fapaneng tsa Hardware tsamaisong ea komporo. E atisa ho sebelisoa ho hokahanya lisebelisoa tse kang likarete tsa litšoantšo, likarete tsa marang-rang, le lisebelisoa tsa polokelo tse kang NVMe SSDs.
A. Tlhaloso le Morero oa PCIe
PCIe e etselitsoe ho sebetsana le data e ngata ka lebelo le holimo. Ke mokokotlo oa likarete tse ngata tsa morao-rao tsa katoloso le lisebelisoa tsa polokelo, tse nolofalletsang litefiso tsa phetisetso ea data ka potlako ha li bapisoa le li-interfaces tsa khale joalo ka SATA kapa PCI.
PCIe e thusa puisano e phahameng ea bandwidth, e fokotsa latency le ho eketsa ts'ebetso ea sistimi ka kakaretso.
Sebopeho se sebelisa puisano ea serial ho e-na le puisano e tšoanang (joaloka PCI ea khale), e ntlafatsang botšepehi ba matšoao le ho nolofalletsa lebelo le phahameng.
Liphetolelo tsa B. PCIe le Tsoelo-pele ea Tsona
Ho bile le liphetolelo tse 'maloa tsa PCIe, e' ngoe le e 'ngoe e ntlafatsa holim'a mofuta o fetileng ho latela lebelo la phetisetso ea data le bandwidth:
PCIe 1.0: 2.5 GT/s (Gigatransfers ka motsotsoana) ka tsela e 'ngoe, e fanang ka 250 MB / s ea bandwidth.
PCIe 2.0: 5.0 GT/s ka tsela e 'ngoe, e menahanang habeli ho fihla ho 500 MB/s.
PCIe 3.0: 8.0 GT/s ka tsela e 'ngoe, e fanang ka 1 GB/s ea bandwidth.
PCIe 4.0: 16.0 GT/s ka lane, e fana ka 2 GB/s bandwidth.
PCIe 5.0: 32.0 GT/s ka tsela e 'ngoe, e fanang ka 4 GB/s bandwidth.
| Phetolelo ea PCIe | Sekhahla sa phetisetso ea data (GT/s) | Bandwidth ka Lane |
|---|---|---|
| PCIe 1.0 | 2.5 GT/s | 250 MB/s |
| PCIe 2.0 | 5.0 GT/s | 500 MB/s |
| PCIe 3.0 | 8.0 GT/s | 1 Gbps |
| PCIe 4.0 | 16.0 GT/s | 2 Gbps |
| PCIe 5.0 | 32.0 GT/s | 4 Gbps |
C. Kamoo PCIe e Sebetsang Kateng: Lanes le Bandwidth
PCIe e sebetsa e sebelisa litselana, e leng litsela tseo data e fetisoang ka tsona. Tsela e 'ngoe le e' ngoe e na le lipara tse peli tsa lithapo: e 'ngoe ke ea ho romela le ea ho amohela data. Lisebelisoa li ka sebelisa lipalo tse fapaneng tsa litselana:
x1: tsela e le 'ngoe
x4: Litsela tse 'nè
x8: Litsela tse robeli
x16: Litsela tse leshome le metso e tšeletseng (tse sebelisoang hangata bakeng sa likarete tsa litšoantšo)
Palo ea litselana e etsa qeto ea hore na sebaka sa marang-rang se hokae, kahoo lisebelisoa tse nang le litselana tse ngata, joalo ka li-GPU, li ka fetisetsa lintlha tse ngata ka nako e le 'ngoe, li fana ka ts'ebetso e ntlafetseng lits'ebetsong tse boima tse kang lipapali le 3D rendering.
D. Melemo ea PCIe bakeng sa Lisebelisoa tsa polokelo
Ha e sebelisoa bakeng sa lisebelisoa tsa polokelo, PCIe e fana ka melemo e mengata ho feta li-interface tsa khale tse kang SATA:
Lebelo le potlakileng la phetisetso ea data, le lebisang ho ntlafatseng linako tsa ho qala le ho fetisoa ha lifaele ka potlako.
Scalability: PCIe slots e ka ts'ehetsa lisebelisoa tse ngata, e lumellang hore ho be le litlhophiso tse sebetsang hantle.
Nako e tlase: PCIe e fokotsa nako eo e e nkang hore data e tsamaee lipakeng tsa lisebelisoa, e etsa hore e be e loketseng li-NVMe SSD.
Ka ho sebelisa PCIe, lisebelisoa tsa sejoale-joale tsa polokelo tse kang li-NVMe SSD li ka fihla ka lebelo le holimo haholo ho feta mahlale a khale, tsa fetola ts'ebetso ea komporo likarolong tse fapaneng, ho tloha papaling ho isa polokelong ea data ea khoebo.
3.Ke eng NVMe (Non-Volatile Memory Express)?
| Phetolelo ea NVMe | Sekhahla sa Phetiso ea Lintlha | Likarolo tsa Bohlokoa |
|---|---|---|
| NVMe 1.1 | Ho fihla ho 2GB/s | Tokollo ea pele, tšehetso ea mantlha bakeng sa PCIe 3.0 |
| NVMe 1.2 | Ho fihlela ho 3.5 GB/s | Taelo e ntlafalitsoeng, taolo e ntle ea matla |
| NVMe 1.3 | Ho fihlela ho 4GB/s | Taolo e ntle ea mocheso le ts'ireletso e matlafalitsoeng |
| NVMe 1.4 | Ho fihlela ho 5GB/s | Botebo bo ekelitsoeng ba mela, bo ntlafalitse tokiso ea liphoso |
| NVMe 2.0 | Ho fihlela ho 7GB/s | E tšehetsa PCIe 4.0/5.0, scalability e betere bakeng sa ts'ebeliso ea khoebo |
4.PCIe vs NVMe: Phapang ea Bohlokoa
Ts'ebetso: PCIe le NVMe in Action
| Theknoloji ea polokelo | Bala Lebelo | Ngola Lebelo | Ho lieha ho fihla |
|---|---|---|---|
| PCIe 3.0 SSD | 3-4 GB/s | 2-3 GB/s | Tlase |
| PCIe 4.0 SSD | 5-7 GB/s | 4-6 GB/s | Tlase Haholo |
| NVMe (PCIe 3.0) | 3-4 GB/s | 2-3 GB/s | Tlase ka ho Fetisisa |
| NVMe (PCIe 4.0) | 7-10GB/s | 5-7 GB/s | Tlase Haholo |
U ka khetha joang lipakeng tsa PCIe le NVMe?
| Sebopeho | PCIe (ntle le NVMe) | PCIe NVMe SSD |
|---|---|---|
| Lebelo la Phetiso ea Lintlha | E itekanetseng (ho fihla ho 2-3 GB/s) | E phahameng haholo (ho fihla ho 7GB/s) |
| Ho lieha ho fihla | E phahameng | Tlase |
| Botebo ba Lethathamo | Moedi | E phahameng (e tšehetsa parallelism) |
| Theko | E Affordable haholoanyane | Litheko tsa Premium |
| Ho lumellana | E pharaletseng (e lumellana le litsamaiso tse ngata) | E hloka lisebelisoa tse lumellanang le NVMe |
C. Litšenyehelo khahlano le Ts'ebetso
Li-SSD tsa PCIe NVMe hangata li theko e boima haholo ka lebaka la theknoloji ea tsona e tsoetseng pele le ts'ebetso e phahameng. Leha ho le joalo, melemo ea lebelo le holimo e ka lokafatsa litšenyehelo tsa basebelisi ba motlakase le libaka tsa likhoebo, haholoholo bakeng sa lik'homphieutha tsa rack tsa indasteri tse hlokang hardware e sebetsang hantle haholo.
Li-SSD tsa PCIe ntle le NVMe li ntse li ka fana ka lintlafatso tse kholo tsa ts'ebetso ho feta li-SATA SSD, tsa li etsa khetho e tiileng bakeng sa basebelisi ba tsotellang tekanyetso kapa ba nang le litlhoko tse itekanetseng. Likhetho tsena li boetse li tumme bakeng sa PC ea indasteri e nang le NVIDIA GPU litsamaiso tse lekanyang tšebetso le litšenyehelo.
D. Bopaki ba Bokamoso
Haeba u batla theknoloji ea bopaki ba nako e tlang, NVMe ke eona e hapileng ka ho hlaka. Ha lits'ebetso li hloka ts'ebetso ea data ka potlako, li-PCIe NVMe SSD li tla tsoelapele ho fetoha le ho fana ka lebelo le holimo ka PCIe 4.0/5.0. Sena se ba etsa khetho e nepahetseng bakeng sa likhoebo tse batlang baetsi ba lik'homphieutha tsa indasteri ho fihlela litlhoko tsa moloko o latelang oa likopo. Tse ngata indasteri raka mount likhomphutha e se e ntse e tšehetsa mahlale ana hore a lule a le ka pele ho mothinya.
E. Qetello: Etsa Khetho e Nepahetseng Bakeng sa Litlhoko tsa Hao
Khetha PCIe NVMe haeba u hloka ts'ebetso e phahameng haholo bakeng sa mesebetsi e kang papali, tlhahiso ea livideo, kapa komporo e sebetsang hantle haholo ha u sebelisa. Li-PC tsa indasteri tsa Advantech tse etselitsoeng libaka tse hlokang ka ho fetisisa.
Khetha PCIe SSD ntle le NVMe haeba u hloka polokelo e potlakileng ho feta li-SATA SSD tsa setso empa u sa hloke lebelo le holimo-limo le latency e tlase e fanoang ke NVMe. A K'homphieutha ea 4U rackmount e ka fana ka tharollo e theko e tlaase ntle le ho sekisetsa ts'ebetsong ea bohlokoa ea polokelo.
