Lub caij ntuj sov dhau los peb Optane DC Persistent Memory - Optane module-based nco hauv DIMM hom. Raws li tau tshaj tawm thaum ntawd, kev xa khoom ntawm Optane strips pib nyob rau lub quarter thib ob ntawm 2019, los ntawm lub sijhawm cov ntaub ntawv txaus tau sau txog lawv, uas yog qhov tsis txaus, thaum lub sijhawm tshaj tawm. Yog li, hauv qab ntawm qhov txiav yog cov kev qhia tshwj xeeb thiab cov qauv siv. , nrog rau txhua hom infographics.
Yog li, raws li twb tau hais lawm, Optane DC Persistent Memory modules (Optane DC PM) tau teeb tsa hauv cov qauv DDR4 DIMM qhov txuas, txawm li cas los xij, lawv siv yuav tsum muaj kev txhawb nqa los ntawm lub cim xeeb tswj, yog li hom kev nco no tsuas yog siv tau rau tam sim no nrog thib ob tiam. Intel Xeon Scalable Kub lossis Platinum processors. Nyob rau hauv tag nrho, ib qho Optane DC PM module tuaj yeem ntsia tau rau ib lub cim xeeb channel, uas yog, mus txog 6 modules ib lub qhov (socket), uas yog, tag nrho ntawm 3 TB lossis 24 TB rau 8-socket server.
Optane DC PM tuaj hauv 3 qhov ntau thiab tsawg: 128, 256 thiab 512 GB - loj dua li DDR DIMM sticks tam sim no. Muaj ob txoj hauv kev uas nws tuaj yeem siv tau thiab cuam tshuam nrog kev nco ib txwm muaj.
- Hom kev nco - tsis xav tau kev hloov kho daim ntawv thov. Hauv hom no, Optane DC PM yog siv los ua qhov chaw nyob ntawm RAM, thiab cov ntim muaj nyob ntawm cov tsoos DRAM yog siv los ua cache rau Optane. Hom kev nco tso cai rau koj los muab cov ntawv thov nrog cov nyiaj tseem ceeb ntawm RAM ntawm tus nqi qis dua, uas tuaj yeem yog qhov tseem ceeb thaum hosting virtual machines, loj databases, thiab lwm yam. Nws yuav tsum tau borne nyob rau hauv lub siab hais tias nyob rau hauv no hom, Optane DC Persistent Memory yog volatile, txij li thaum cov ntaub ntawv nyob rau hauv nws yog encrypted nrog ib tug yuam sij uas ploj thaum reboot.
- Direct access hom - Cov ntawv thov thiab software tuaj yeem nkag ncaj qha rau Optane DC PM, ua kom yooj yim rau kev hu xov tooj. Tsis tas li ntawd hauv hom no, koj tuaj yeem siv cov APIs uas twb muaj lawm, uas tso cai rau koj ua haujlwm nrog kev nco ua SSD thiab, tshwj xeeb, khau raj los ntawm nws. Lub kaw lus pom Optane DC PM thiab DRAM ua ob lub cim xeeb ywj pheej. Koj qhov zoo dua yog qhov loj, tsis hloov pauv, ceev thiab txhim khu kev qha rau kev siv cov ntaub ntawv siv ntau thiab cov kev xav tau.
Ib qho kev xaiv nruab nrab kuj tseem tuaj yeem ua tau: qee qhov Optane DC PM strips siv rau hauv hom nco, thiab qee qhov siv rau hauv hom kev nkag ncaj qha. Cov slides tom ntej no qhia txog cov txiaj ntsig ntawm kev siv Intel Optane DC Persistent Memory rau virtual tshuab hosting.
Tam sim no cia peb muab cov yam ntxwv ua haujlwm ntawm lub cim xeeb modules.

Thiab thaum kawg, txog tus nqi. Intel cov lus pom zoo cov nqi tseem tsis tau tshaj tawm, tab sis ntau lub tuam txhab cov koom tes ua lag luam tau pib sau cov ntawv xaj ua ntej, ntawm $ 850 - $ 900 rau 128 GB stick thiab $ 2 - $ 700 rau 2 GB. 900 GB tseem tsis tau muab, pom meej, lawv yuav tshwm sim tom qab lwm tus. Yog li, chav tsev nqi pib ntawm $ 256 ib GB, uas yog piv rau tus nqi ntawm ib gigabyte ntawm RDIMM neeg rau zaub mov nco.
