I-Intel Optane DC Persistent Memory, ngemva konyaka

Ngehlobo eledlule thina kumenyezelwe kubhulogi I-Optane DC Persistent Memory - Imemori esekwe kumojula ye-Optane 3D XPoint ngefomethi ye-DIMM. Njengoba kwamenyezelwa ngaleso sikhathi, ukulethwa kwemichilo ye-Optane kwaqala ngekota yesibili ka-2019, ngaleso sikhathi ulwazi olwanele lwase luqoqiwe ngabo, olwalushoda kakhulu ngaleso sikhathi, ngesikhathi sesimemezelo. Ngakho-ke, ngaphansi kokunqunywa kukhona imininingwane yobuchwepheshe namamodeli okusetshenziswa. Inkumbulo Eqhubekayo ye-Optane DC, kanye nazo zonke izinhlobo ze-infographics.

Ngakho-ke, njengoba sekushiwo, amamojula we-Optane DC Persistent Memory (Optane DC PM) afakwe ezindaweni ezijwayelekile ze-DDR4 DIMM, noma kunjalo, ukusetshenziswa kwawo kudinga ukusekelwa kwesilawuli sememori, ngakho lolu hlobo lwenkumbulo lungasetshenziswa kuphela okwamanje ngesizukulwane sesibili. I-Intel Xeon Scalable Gold noma i-Platinum processors. Sekukonke, imojula eyodwa ye-Optane DC PM ingafakwa ngeshaneli yememori ngayinye, okungukuthi, amamojula afinyelela ku-6 isokhethi ngalinye, okungukuthi, ingqikithi ye-3 TB noma i-24 TB ngeseva yesokhethi engu-8.

I-Optane DC PM iza ngosayizi wamamojula ama-3: 128, 256 kanye no-512 GB - inkulu kakhulu kunezinti ze-DDR DIMM ezitholakalayo njengamanje. Kunezindlela ezimbili eziyinhloko engasetshenziswa ngayo futhi ihlanganyele nenkumbulo yendabuko.

• Imodi yenkumbulo - ayidingi ukuguqulwa kohlelo lokusebenza. Kule modi, i-Optane DC PM isetshenziswa njenge-RAM eyinhloko ekwaziyo ukubhekana nayo, futhi ivolumu etholakalayo ye-DRAM evamile isetshenziswa njengenqolobane ye-Optane. Imodi yememori ikuvumela ukuthi unikeze izinhlelo zokusebenza ngamanani abalulekile we-RAM ngezindleko eziphansi kakhulu, ezingabaluleka lapho ubamba imishini ebonakalayo, imininingwane emikhulu, njalonjalo. Kufanele kukhunjulwe ukuthi kule modi, i-Optane DC Persistent Memory iyashintshashintsha, njengoba idatha ekuyo ibethelwe ngokhiye olahlekayo uma uqalisa kabusha.
• Imodi yokufinyelela okuqondile - Izicelo nesofthiwe ingafinyelela ngokuqondile ku-Optane DC PM, yenza uchungechunge lwezingcingo lube lula. Futhi kule modi, ungasebenzisa ama-API wesitoreji akhona, okuvumela ukuthi usebenze ngememori njenge-SSD futhi, ikakhulukazi, uqalise kuyo. Uhlelo lubona i-Optane DC PM ne-DRAM njengamachibi enkumbulo amabili azimele. Inzuzo yakho inkulu, ayiguquki, isitoreji esisheshayo nesithembekile sezinhlelo zokusebenza ezidinga idatha kanye nezidingo zesistimu.

Inketho emaphakathi nayo ingenzeka: eminye imichilo ye-Optane DC PM isetshenziswa kwimodi yememori, kanti eminye isetshenziswa kumodi yokufinyelela okuqondile. Isilayidi esilandelayo sibonisa izinzuzo zokusebenzisa i-Intel Optane DC Persistent Memory ekusingatheni umshini obonakalayo.

Manje ake sinikeze izici zokusebenza zamamojula wememori.

Futhi ekugcineni, mayelana nenani. Izintengo ezinconyiwe ze-Intel ezisemthethweni azikakashicilelwa, kodwa idlanzana labalingani benkampani abahwebayo sebeqalile ukuqoqa ama-oda angaphambili, ngo-$850 - $900 ngenduku engu-128 GB kanye no-$2 - $700 ngo-2 GB. I-900 GB ayinikeziwe okwamanje, ngokusobala, izovela kamuva kunabanye. Ngakho-ke, izindleko zeyunithi ziqala kusuka ku-$ 256 nge-GB ngayinye, eqhathaniswa nenani le-gigabyte yememori yeseva ye-RDIMM.
