Intel Optane DC Persistent Memory, otu afọ ka e mesịrị

Oge okpomọkụ ikpeazụ anyị ekwuputara na blọgụ Ebe nchekwa Optane DC na-adịgide adịgide - ebe nchekwa dabere na modul Optane 3D XPoint na usoro DIMM. Dị ka ekwuru n'oge ahụ, nnyefe nke Optane strips malitere na nkeji nke abụọ nke 2019, bụ nke oge zuru ezu ozi gbasara ha, nke na-enweghị mgbe ahụ, n'oge ọkwa ahụ. Yabụ, n'okpuru ịkpụ bụ nkọwa teknụzụ na ụdị ojiji. Ebe nchekwa Optane DC na-adịgide adịgide, yana ụdị infographics niile.

Yabụ, dị ka ekwuru na mbụ, etinyere Optane DC Persistent Memory modules (Optane DC PM) na oghere DDR4 DIMM ọkọlọtọ, agbanyeghị, ojiji ha chọrọ nkwado site na njikwa ebe nchekwa, yabụ enwere ike iji ụdị ebe nchekwa a naanị ugbu a na ọgbọ nke abụọ. Intel Xeon Scalable Gold ma ọ bụ Platinum processors. Na mkpokọta, enwere ike itinye otu Optane DC PM modul kwa ọwa ebe nchekwa, ya bụ, ihe ruru modul 6 kwa oghere, ya bụ, ngụkọta nke 3 TB ma ọ bụ 24 TB maka sava 8-socket.

Optane DC PM na-abịa na nha modul 3: 128, 256 na 512 GB - nke ukwuu karịa osisi DDR DIMM dị ugbu a. Enwere isi ụzọ abụọ enwere ike iji ya wee mekọrịta na ebe nchekwa ọdịnala.

• Ụdị ebe nchekwa - anaghị achọ mgbanwe ngwa ọ bụla. Na ọnọdụ a, a na-eji Optane DC PM mee ihe dị ka RAM bụ isi a na-ekwu okwu, na olu dịnụ nke DRAM omenala na-eji dị ka cache maka Optane. Ọnọdụ ebe nchekwa na-enye gị ohere ịnye ngwa nwere nnukwu RAM na ọnụ ahịa dị ala nke ukwuu, nke nwere ike ịdị mkpa mgbe ị na-ebugharị igwe mebere, nnukwu ọdụ data na ihe ndị ọzọ. Ekwesịrị iburu n'uche na na ọnọdụ a, Optane DC Persistent Memory na-agbanwe agbanwe, ebe ọ bụ na ejiri igodo ezoro ezo data dị na ya.
• Ụdị nnweta ozugbo - Ngwa na ngwanrọ nwere ike ịnweta Optane DC PM ozugbo, na-eme ka agbụ oku dị mfe. Nakwa na ọnọdụ a, ị nwere ike iji API nchekwa dị ugbu a, nke na-enye gị ohere iji ebe nchekwa rụọ ọrụ dịka SSD na, karịsịa, buut site na ya. Usoro ahụ na-ahụ Optane DC PM na DRAM dị ka ọdọ mmiri nchekwa abụọ nwere onwe ha. Uru gị bụ nnukwu ọnụ ọgụgụ, nke na-adịghị agbanwe agbanwe, nchekwa ngwa ngwa na nke a pụrụ ịdabere na ya maka ngwa ngwa data na mkpa usoro.

Nhọrọ etiti ga-ekwe omume: a na-eji ụfọdụ ibe Optane DC PM na ọnọdụ ebe nchekwa, yana ụfọdụ a na-eji ya na ọnọdụ nnweta ozugbo. Ihe mmịfe na-esote na-egosi uru nke iji Intel Optane DC Persistent Memory maka nnabata igwe mebere.

Ugbu a, ka anyị nye njirimara arụmọrụ nke modul ebe nchekwa.
