Intel Optane DC Persistent Memory, patatha chaka chimodzi

Chaka chatha ife adalengezedwa pa blog Optane DC Persistent Memory - Optane module-based memory 3D XPoint mu mawonekedwe a DIMM. Monga zidalengezedwa pamenepo, kutumizidwa kwa mikwingwirima ya Optane kudayamba mgawo lachiwiri la 2019, pomwe nthawi yomwe zidziwitso zokwanira zidasonkhanitsidwa za iwo, zomwe zidasoweka panthawiyo, panthawi yolengeza. Choncho, m'munsimu odulidwawo pali luso lapadera ndi zitsanzo za ntchito. Optane DC Kulimbikira Memory, komanso mitundu yonse ya infographics.

Chifukwa chake, monga tafotokozera kale, ma module a Optane DC Persistent Memory (Optane DC PM) amayikidwa mu mipata yokhazikika ya DDR4 DIMM, komabe, kugwiritsa ntchito kwawo kumafunikira thandizo kuchokera kwa woyang'anira kukumbukira, kotero kukumbukira kwamtunduwu kutha kugwiritsidwa ntchito pakadali pano ndi m'badwo wachiwiri. Intel Xeon Scalable Gold kapena Platinum processors. Pazonse, gawo limodzi la Optane DC PM litha kukhazikitsidwa panjira yokumbukira, ndiye kuti, mpaka ma module 6 pa socket, ndiye kuti, 3 TB kapena 24 TB pa seva 8-socket.

Optane DC PM imabwera m'magawo atatu: 3, 128 ndi 256 GB - yayikulu kwambiri kuposa ndodo za DDR DIMM zomwe zilipo pano. Pali njira ziwiri zazikulu zomwe zingagwiritsidwe ntchito ndikulumikizana ndi kukumbukira kwachikhalidwe.

• Memory mode - sichifunikira kusinthidwa kulikonse. Munjira iyi, Optane DC PM imagwiritsidwa ntchito ngati RAM yayikulu yolumikizira, ndipo voliyumu yomwe ilipo ya DRAM yachikhalidwe imagwiritsidwa ntchito ngati cache ya Optane. Memory mode imakupatsani mwayi wopereka mapulogalamu ndi kuchuluka kwa RAM pamtengo wotsika kwambiri, womwe ungakhale wofunikira pakusunga makina enieni, ma database akulu, ndi zina zotero. Tiyenera kukumbukira kuti munjira iyi, Optane DC Persistent Memory ndi yosasunthika, popeza deta yomwe ilimo imasungidwa ndi kiyi yomwe imatayika pakuyambiranso.
• Kufikira molunjika - Mapulogalamu ndi mapulogalamu amatha kulowa mwachindunji ku Optane DC PM, kufewetsa kuyimbira foni. Komanso mumachitidwe awa, mutha kugwiritsa ntchito ma API osungira omwe alipo, omwe amakulolani kuti mugwiritse ntchito kukumbukira ngati SSD ndipo, makamaka, boot kuchokera pamenepo. Dongosolo limawona Optane DC PM ndi DRAM ngati maiwe awiri odziyimira pawokha. Ubwino wanu ndi waukulu, wosasunthika, wofulumira komanso wodalirika wosungirako ntchito zogwiritsa ntchito deta komanso zosowa zamakina.

Njira yapakatikati ndiyothekanso: mizere ina ya Optane DC PM imagwiritsidwa ntchito pokumbukira, ndipo ina imagwiritsidwa ntchito polowera mwachindunji. Chithunzi chotsatira chikuwonetsa ubwino wogwiritsa ntchito Intel Optane DC Persistent Memory pakuchititsa makina enieni.

Tsopano tiyeni tipereke mawonekedwe a magwiridwe antchito a ma memory module.

Ndipo potsiriza, za mtengo. Mitengo yovomerezeka ya Intel sinasindikizidwebe, koma angapo omwe akuchita nawo malonda akampaniyo ayamba kale kutolera zoyitanitsa, pa $ 850 - $ 900 pandodo ya 128 GB ndi $ 2 - $ 700 ya 2 GB. 900 GB sinaperekedwe pano, mwachiwonekere, idzawonekera mochedwa kuposa ena. Chifukwa chake, mtengo wagawo umayamba kuchokera ku $ 256 pa GB, yomwe ikufanana ndi mtengo wa gigabyte wa kukumbukira kwa seva ya RDIMM.
