Ukuziqonda Kwemfundo Server Umfundo Wengunya Lokusebenza
Imemori yomkluli kusemandleni okhokhelwa kwindawo yedatha, njengendlela ephakeme phakathi kwimali evela kumsebenzi nokufinyelela isivinini. Imfundo yokusebenzisa i-computer namhlanje iyaphindeka kakhulu imithombo yesimemo, nge DDR4 ne DDR5 efana nezintandokazi ezihlukileyo zezixhobo zokugcina idatha. Ngelixa kwezigaba zasimahala ziyakhula nokuphatha izindlela eziphezulu, ukuziqonda le miqondo yezixhobo zokugcina idatha kuyafunekayo kubaprofesheni be IT nabasebenzi basezixhobeni.
Ukulungiswa kwezinhlelo zememori yaserver kuyashiywa izidingo ezinzima zezinkokheli zamanje. Kusukela ku-Artificial Intelligence nokufunda kwamakhina, kuze kube ngokuzinconyiselana ngemizuzu yokuvula nokubalisa, izidingo zememori engcono ne-engakwenzileyo zihlaba ukuvutha kule ndawo. Ukuhambisana kuka-DDR4 ku-DDR5 kuyindawo eyinkimbinkimbi kuleli henguquko, ekunika amandla amasha ekulungiseni inkundla yedatha nesimo esingcono.
I-Technology Yememori ye-Server DDR4
Uhlelo Lwaseko Namasiphekelo
Imemori ye-Server DDR4 yayisilingo sesivikelo ngaphandle kokuthi yayiphinde yavela ngo-2014, ibe yanelisa imfanelelo engcono kumsebenzi wokubala we-enterprise. Iyasembenza kumafrequence okusekelwe phakathi kwe-2133 MHz ne-3200 MHz, lezi zimodiwu zinezici ezingcono zokusebenzisa ivholthi njengako kwayo emva, ngokuvamile isebenza ngama-1.2V. Lokhu kunciphisa ivholthi esebenzayo kwenza ukuthi i-DDR4 ibe yilwahluko elihle kumadatshibha angathanda ukusebenzisa imithwalo yamandla.
Umbiko wememori ye-DDR4 yomnqophiso uyathunyelana ngezinkinga ezimbili, njengezibhanki zezigaba ngokugooda kwezimpendulo nezilinganiso, ngaphezu kwemproving yokuthola nokulungisa iziphazamiso. Lezi zinto zakhonjiswa njengazo zibalulekile ukugcina ubumnandi bomdala emsebenzini wobuchwepheshe, ngelixa izinketho eziphakanyisiweyo zemoduli ezifaka kusukela ku-256GB ngalinye i-DIMM zavuselela ukuthuthuka komsebenzi obalulekile kumemori.
Amahlelo amaphi
Imoduli yememori ye-DDR4 ihlanya ekunikezeni imfundo engcono phakathi kwezinhlelo zonke zomnqophiso. Ngokuguqulwa kwe-datha okuqhubeka kusukela ku-17GB/s ku-25.6GB/s, imemori ye-DDR4 yomnqophiso inika ibhande elingcono kakhulu kubuningi bezentengiso zamanje. Umlando wesayensi we-teknoloji wabangela futhi ukuthi kutholakale amakhontrola amahle angememori nakwenzululwazi eyisiseko phakathi kwezinhlelo zomnqophiso ezahlukene.
Ukuphatha kwe-Latency eGigaba leDDR4 libe libe lisebenziswa ngeminyaka, lithobela izakhono ezithandabuzekileyo nezihlakaniphileyo. I-CAS latency iholela phakathi kwe-CL15 kuze kube yi-CL22, ibonelela equilibrium phakathi kwezindlela zokufinyelela nokuthembeka okuninzi kwamathulwa abenamandla ukusebenzisa kuzimisele.
Ukuthuthukwano kweGigaba leDDR5 yeSeva
Ukuguquka Kuhlaka Okuqhubekayo
I-DDR5 ibonakala njengoko uhlelo olubalulekile emsakathini wogigaba lweseva, lukhuluma izinguquko ezibalulekile kumshinelodi we-gigaba. Izinguquko ezibaluleke kakhulu kuzo kukhona ukudunyelwa kwebhlaste ikuya ku-16 bits, uhlelo oluthuthukile we-channel onawo amakhanda amabili angaphansi kwe-32-bit ngalunye igilasi, nokuthuthukwa kwezimali nge-inhlangano yezimali ngaphakathi kwegilasi. Lezi zinguquko zivumela i-DDR5 ukuba ifinyelele amaxeshana amakhulu kangangokuba ajikeleze inzulu yokusebenza.
Umbono omusha ubandakanya izinkundla zokulungisa impazamo, kanye ne-ECC yekhanda kwindawo yayo kanye nokuthuthukiswa kwezinhlelo zokudala impazamo. Lokhu kusobala kakhulu emazingeni ephepha ephakeme apho ubumfihlakuse benkulumo kuyindilinga. Izizathu zokuphatha amandla e-DDR5 esibhakabhakeni zafakwa futhi ukugcinwa okuncane kwesithunzi, kuvumela ukuthuthukiswa okuhle kemandla ekusetshenziswa ngokwethembeka kwezindleko.
Izinkundla Zokusebenza
I-DDR5 yesibhakabhaka ishukuma izigaba zesiseko sokusebenza ngezikhathi ezizayo ekuqaleni ngo-4800 MHz kanye nezinhlongo ezingena ku-8400 MHz futhi kangcono. Le zikhathi ezide zihlaza izimo eziphumelelayo ezingaphezu kuka-64GB/s ngamoduli, zibonisa ukuqashiselana okubalulekile kusuka ku-DDR4. Umbhalo wesilungu othuthukile wenza futhi ukuphatha okuhle kwezisebenzo ezihambisanayo, kusiza izicelo ezidinga ukuthuthukisa kwe-RAM.
Ukukhula kwezimali eziphilayo zeDDR5 kuyinikeza izikhathi ezihlelwe nezinkinga ezizimile. Nakuba izikhathi zokuqala zeCAS zingaba phakade kangangokwe DDR4, isiphazamiso esigcwele kumsebenzi wasebenzweni unikezwa ngamathuba aphezulu kakhulu nokuthuthukisa kwesayensi.
Ukulinganisa Okulinganiselwe Kwemisebenzi Yezinhlangano
Izivikelo Zemisebenzi
Xa kuhlaziywa izinketho zombandela we-server kumisebenzi ye-enterprise, izivikelo zemisebenzi zibonisa ukwahlukana okukhulu phakathi kwezintambo zeDDR4 ne-DDR5. Kuzindlela ezinezimali ezininayo njengezemisebenzi yedatha nemithombo etholakele imfundo, iDDR5 ibonisa ukuthuthukisa kwebhande yezimali ye-30-50% ikusasa leDDR4. Lokhu kungakwazi ukuze kube yisiphazamiso esibonakalayo kubantu abasebenzisa imisebenzi engenazo imodi engaphezulu noma abasiza amanzi amakhulu ebala labasebenzisi.
Ukuhlaziywa kwezinto eziphathelene kubonisa ukuthi i-DDR5 server memory ikhona kakhulu emizimbeni inqolobane yezibalo nekuprosesa kwezinhla yedatha. Kodwa, umehluko wokusebenza kuyintambo ngokulinganiselwa kwesicelo esithile nokuhlelwa kwegunya. Kumele izihlali zihlaziye ngempela izimo zokusebenza ukuqinisekisa ukuthi okunikezwayo kuyinkululeko engcono futhi kuyavalela ukuthenga teknoloji ye-DDR5.
Ingenako yonke yokusebenzisa
Izimali ezihlobene nethinta ethinta igunya leseva lisuka ngaphandle kwebhenge lokuthenga kuqala. Izimoduli zeDDR5 zilandela imfazwe ngamanje ku-DDR4, kodwa lo msebenti kumele usahlaziywe ngokulinganisa nokutholeka kwezimali. Izindlela ezifana nokwaneliseka kwezinsimbi, izidingo zokulahla, nokusebenza ngokwesilingo siziphatha indima ebalulekile ekubekeni umthwalo wokuthengisa.
Izihlakalakahle kumele ziqhubeke nokuzinzela iziphumo zokwahlukanisa kwazo kwezinkumbulo zabo. Njengoba i-DDR4 ibonakala ngotechiniki eqinile nezenzo ezitholakalayo, i-DDR5 inikeza indalo elidlonge futhi inomthelela wokuthuthana okuphuculi ngemikhawulo ephakeme njengoba iyatholakala. Umniko phakathi kwezinkumbulo zeDDR4 neDDR5 zezinhlanganiseli zingaba yindlela yokulungana kwebhajethi yamanje nembulali yamanje.
Umkhondo Wokusebenzisa Futhi Izimpendulo Ezilungile
Ukubhalela Kwemigudu
Ukuhlanjulwa phakathi kwezinhlelo zezinkumbulo kudinga ukubhalela kahle futhi uqiniseke ukuthi uhlinze iziseko zakho. Izihlakalakahle ezixoxa ngokuthuthana kumaDDR5 kumele zibone ubunikwini bazo bezinhlelo zakho zamandla, izidingo zabasebenzi, nokuthi kufanele kube yini igunya. Indlela ethunywa ngokuphindaphindiwa kuyisiphiwo esihle, sivumela ukuchazwa nokuvikela kwezinhlelo ezintsha.
Izinqumo ezizenzakalisekayo zihlanganisa ukuphawula kakhulu kwezinhlelo-mgudu eziphambili ngokulungiswa kwamatheni, ukubala kwezidingo zokunika amandla nokulima, nokuthuthukisa izibonakude zokubuyisela emuva. Amagunya e-IT futhi kufanele abheke ixesha lekhiye lehlangothi yehlangothi kanye nokuqashisa kwezilungiso zemitholampilo ngokuhambisana nezinyathelo eziningi zokuvuselela uhlelo lokusebenza.
Amathulwana Okuvuselela
Ukuhlanganisa okuningi kwebenefiti yokuziphatha kwimitholampilo yeserver kudinga ukuqaphela uhlelo lwokulungiswa kanye nokuvuselela. Kwi-DDR5, lokhu kuhlanganisa ukulungiswa kwamatheni wokugcina, izilungiso ze-BIOS, nezilungiso zesistemu yokusebenza ukuze kutholekeke konke uhlelo olisha. Ukubeka isitebhile kanye nokulungisa kohlelo kunciphisa ukuthi imitholampilo yezimvo iphathelene kanjalo kuwo wonke amacebo.
Kufanele kubeke amathuluzi akhokwe kahle nokulungisa izinhlelo ukuze kubekwe imizamo yememori, kutholakale izinkinga ezinako, nokugcina imisebenzi emehlweni. Lokhu kuhlanganisa ukubala okuqhubekayo kwezinkomba zokusetshenziswa kwememori, izilinganiso zemposiso, nezindlela zokusebenza ukuze kusizwe izinyathelo ezengeziweyo zokuphucula.
Imibuzo Evame Ukubuzwa
