I-Intel Optane DC iMemori eZingileyo, emva konyaka

Kwihlobo elidlulileyo thina ibhengezwe kwibhlog Imemori eqhubekayo ye-Optane DC-imemori esekwe kwimodyuli ye-Optane 3D XPoint kwifomathi ye-DIMM. Njengoko kwakubhengezwe ngoko, ukuhanjiswa kwemichilo ye-Optane kwaqala kwikota yesibini ka-2019, ngelo xesha ulwazi olwaneleyo lwaluqokelelwe ngabo, olwalunqongophele ngelo xesha, ngexesha lokubhengezwa. Ke, ngaphantsi kokusikwa ziinkcukacha zobugcisa kunye neemodeli zokusetyenziswa. I-Optane DC eZingisayo kwiMemori, kunye nazo zonke iintlobo ze-infographics.

Ke, njengoko sele kukhankanyiwe, iimodyuli ze-Optane DC Persistent Memory (Optane DC PM) zifakwe kwiindawo zokubeka eziqhelekileyo ze-DDR4 DIMM, nangona kunjalo, ukusetyenziswa kwazo kufuna inkxaso evela kumlawuli wememori, ngoko olu hlobo lwememori lunokusetyenziswa kuphela ngoku kunye nesizukulwana sesibini. I-Intel Xeon iScalable Gold okanye iiprosesa zePlatinam. Iyonke, imodyuli enye ye-Optane DC PM inokufakwa kwishaneli yememori, oko kukuthi, ukuya kwiimodyuli ze-6 kwisokethi nganye, oko kukuthi, i-3 TB okanye i-24 TB nge-8-socket server.

I-Optane DC PM ifika kwiimodyuli ze-3: i-128, i-256 kunye ne-512 GB - inkulu kakhulu kunezinti ze-DDR DIMM ezikhoyo ngoku. Kukho iindlela ezimbini eziphambili ezinokusetyenziswa kunye nokusebenzisana nememori yendabuko.

• Imowudi yenkumbulo - ayifuni naluphi na utshintsho lwesicelo. Kule modi, i-Optane DC PM isetyenziswe njengeyona RAM idilesi, kwaye inani elikhoyo le-DRAM yendabuko isetyenziswe njenge-cache ye-Optane. Imowudi yeMemori ikuvumela ukuba unikeze izicelo ngexabiso elibalulekileyo le-RAM ngexabiso eliphantsi kakhulu, elinokubaluleka xa ubamba oomatshini bokwenene, oovimba beenkcukacha ezinkulu, njalo njalo. Gcina ukhumbula ukuba kule mowudi, iMemori ye-Optane DC eZingileyo iyaguquguquka, kuba idatha ekuyo iguqulelwe ngokuntsonkothileyo ngesitshixo esilahlekileyo xa kuqalwa ngokutsha.
• Indlela yokufikelela ngokuthe ngqo - Izicelo kunye nesoftware inokufikelela ngokuthe ngqo kwi-Optane DC PM, eyenza lula ikhonkco lokufowuna. Kwakhona kule modi, ungasebenzisa i-APIs yokugcina ekhoyo, ekuvumela ukuba usebenze ngememori njenge-SSD kwaye, ngokukodwa, ukuqala kuyo. Inkqubo ibona i-Optane DC PM kunye ne-DRAM njengamachibi amabini azimeleyo ememori. Ukuxhamla kwisitoreji esikhulu, esingaguqukiyo, esikhawulezayo, nesithembekileyo kwizicelo ezinzulu kunye neemfuno zenkqubo.

Ukhetho oluphakathi lukwanokwenzeka: ezinye iintambo ze-Optane DC PM zisetyenziswa kwimowudi yememori, kwaye ezinye zisetyenziswa kwimo yokufikelela ngokuthe ngqo. Isilayidi esilandelayo sibonisa iingenelo zokusebenzisa i-Intel Optane DC IMemori eZingisayo yokusingatha umatshini wenyani.

Ngoku makhe sinike iimpawu zokusebenza zeemodyuli zememori.

Kwaye ekugqibeleni, malunga nexabiso. Amaxabiso anconyiweyo e-Intel ayikapapashwa, kodwa inani lamaqabane orhwebo sele eqalisile ukuqokelela ii-odolo zangaphambili, kwi-850 yeedola - i-900 yeedola ze-128 GB kunye ne-2 yeedola - i-700 yeedola ze-2 GB. I-900 GB ayikanikezelwa okwangoku, ngokucacileyo, baya kuvela emva kwexesha kunabanye. Ngaloo ndlela, ixabiso leyunithi liqala ukusuka kwi-256 yeedola nge-GB, efaniswa nexabiso le-gigabyte yememori yomncedisi we-RDIMM.
