Ukubona Izimo Zomkhumbi Zesayensi Yedatha Ngamanje
Umzabalazo womkhumbi weseva ubuye ngokuphakade eminyakeni ethile, ngamathikefthi amasha abonisa imiphumela engahambelani nezindlela zokusebenza kweziseko le-enterprise. Nakuba izindawo zedatha zifuna ukuthutha okunzima kakhulu nokwakha kwezinsimbi, ukukhetha uhlelo lwesimo somkhumbi lweseva sibe yisidingo esibaluleke kakhulu kubaphathisi bezinhlelo nezimali ze-IT. Masibone izihlukaniso ezibalulekile phakathi kwezinhlobo ezilishya zomkhumbi weseva ngamanje futhi sibone konke kuyakhiqizwa kanjani indoda yesiseko le-enterprise.
Uguquko Lwe-DDR Memory Kuzinhlelo Ze-Enterprise
Ukuchwephesheko kanye nokusebenza kwe-DDR4
I-DDR4 ibonakala igenerethi yesine yesimemo se-Double Data Rate, engeza izibophongo ezinkulu kunazo ezandululayo. Isebenza ngamafreqensi ephepha phakathi kwe-2133 MHz ne-3200 MHz, i-DDR4 inikeza ubunjani obubi ngaphandle kokunyusa kwezimali, kanti isebenza ngamathuba angu-288 futhi asebenze ngama-1.2V, okwenzela ukuthi kube yimali-engcono kunazo zonke izinhlanzi ezedlule.
Emazingeni eziphathimandla, i-DDR4 iphumelela ekusikweni kwemfazwe ngokunikezela izici njenge-ECC (Inhlokothambo Yokuqinisekisa Imposiso) kanye nesimiso esisodwa sendawo. Le zici zenzela ukuthi ibe yisizo esihle kumsebenzi omuhle othintekileyo apho ubungako bemoto kuyindima. Umphakathi wempilo we-DDR4 unakekela amakhapasiti amaningi, kusukela ku-4GB ku-256GB ngalinye, ukunikezela izinketho ezifana nezilinganiso zokuthutha kuzo zonke izimo zomshini.
I-DDR5: Isimo Esisha Sokusebenza
I-DDR5 isiphindezelo esisha kakhulu kwizinhlekele zomqondo weserver, ethutha izindlela zokusebenza nokwasebenzisa kahle. Ngemithwalo yokuqala ezingaphezu kwe-4800 MHz nangaphakathi kwe-8400 MHz, i-DDR5 inikeza ibhande eliphelele ngokuphindwe kabili lika-DDR4. Lethulwa linikela izici ezintsha njenge-same-bank refresh ne-decision feedback equalization, ekuvumela imisebenzi emihle kakhulu yomqondo.
Kunjalo, okukhona kakhulu, i-DDR5 inamathuba othile asebenzisana ne-ECC (on-die ECC) namandla ohlelwayo wamandla (PMIC) kumoduli ngamunye. Lezi ziphindezelo zenza kube lula ukugcina idatha nokubophezela amandla ngendlela efanelekileyo, izinto eziphilani kakhulu kuzindawo zezinhlekele zezinhlangano. Indlela yokwandisa umlando we-channel ye-DDR5 ihlenze futhi ukwandisa kakhulu kwezinhlekele, ekusizeni ukuthutha kuzaleni.
Ukuchazwa kweNVDIMM kanye Nezinhlekele Eziqukethe Idatha
Ukufunda Ukulungiswa KweNVDIMM
Ukuchaza kweNon-Volatile Dual In-line Memory Module (NVDIMM) kuyisimo esishintshayo sendlela yokugcina imemori yomnqweno, ekhipha ubunzima be-ememori ezingazange ibe yinkimbini ne-engqulatheko yezixhobo zokugcina. I-NVDIMMs igcina idatha nangona kube sele isayizi siphelile, ihlinza izinkinga ezithile kumsebenzi okudinga ubunzima obuphezulu nokugcinwa kwedatha.
Lolu chaza lukhona ngemigudu engaphezu kanye, kungaphakathi i-NVDIMM-N, eyambisa i-DRAM enjalo nezilonda ze-NAND flash, kanye ne-NVDIMM-P, eyisebenzisa izici ezintsha zememori ephinde iphinde iyasebenza. Lokhu kungeniswa amandla abantu ukukhetha izisombululo ezifanamathela kakhulu izidingo zabo zemisebenzi kanye nezidingo zobunzima.
Imisebenzi Nezimbenefito Ze-NVDIMM
Emazingeni ezenhselela, ubunzima beNVDIMM bakhubazekile kakhulu kumsebenzi ofuna ukuzimisa ngokushesha emva kwekhuba elingavimbiwe. Izinhlelo zokuphatha izinhlelo zedatha, ukuprosesa kwezimali, nokuhlola ngokusheshayo kungcono kakhulu ngokuthi kugcine indawo yedatha ngaphandle kokulahleka kokuqhubeka. Lobunzima bahlukanisa ngempela phakathi kwegumbi lokugcina neyigumbi, bethula izinqumo ezintsha zokuphatha idatha.
Ukusebenzisa izisombululo zeNVDIMM kungakwala ixesha lokuzimisa kwezinhlelo futhi kube lula ngaphezu kwemfundo yokuphila kwezisebenzi. Amabhizinisi abasebenzayo ngezimali ezibalweni noma ukuprosesa kwedatha ngokusheshayo ayithobela kakhulu inkinga yeNVDIMM yokugcina ubunzima bedatha emva kwebhuba elingavimbiwe ngelikamu ekhomba amandla okusebenza kwegumbi.
Izidingo Zokusebenza Nezinqumo Zokusebenzisa
Ukuhlaziywa Kwe-Bandwidth Nenhlaziyo
Xa kubalwa izinhlobo zomkhumbi weserver, ukuzifundisa okuphathelene nokuxhumana phakathi kwebandla ne-lateni kumele kube lula. I-DDR5 inikeza i-bandwidth esobala kungeya e-DDR4, kodwa izimpendulo ezibaleni kusengaphambi kungaba nenhliziyo enkulu. Izisulwa ze-NVDIMM, nakuba zinikeza amandla ethulwini, kumele azimiselwe ngokujulile ngokulinganisa kuzo zonke izinkomba zokusebenza kuningi yomkhumbi ongashintshwa.
Abakhethi besistimu kumele balondolozo lezi zinto ngokulinganisa nokuthinte kwesicelo, ukohlaza izindima zemisebenzi nezidingo zokusebenza. Isikhetho phakathi kwezinhlobo zomkhumbi njalo zihlangana nokuhlukana phakathi kwezimali ezimbili, izindleko, nezidingo ezithile njengekugcina idatha noma amandla ekulungiseni impazamo.
Izinqumo Ezinezindleko Eziphansi Zokhetho Kwe-Memory
Ukusebenzisa umyalo wemfazwe ongcono kufuneka kube ngcono ukuzimisa izinkinga zombango nokudinga kokusebenza. Njengoba iDDR5 ibonakala njengendlu yeqiniso lemfazwe yesiphequluli, into yayo eyinhlobonhlobo kungaba akuyikwamukeli ukuthi ngokushesha wonke umsebenzi. Kumele amathuba atholelwa futhi kugcwaliswe izidingo zabo zithile bese kucacishwa izindlela ezihlangene ezigcine izici ezahlukene zemfazwe ukuze kugcinwe ubunzima nezindleko.
Ukulungiswa ngokudala kumele kube nemthetho yokunciphisa izidinga zokuthutha phambili kanye nezilongo ezizothinta. Ukuthola amandla okuvuselela noma okuthutha imfazwe kuthatha indima ethile ngemuva kokuthi izidinga zokuprosesa idatha zakhela kanye nezici ezintsha zemfazwe zibonakala.
Imibuzo Evame Ukubuzwa
Iziphi izinto ezifanele zibangise ukukhetha phakathi kukaDDR4 noDDR5 kumasevisi?
Isinqumo kufanele sisekelwe ezintweni eziningana ezibalulekile ezihlanganisa izidingo zokusebenza, izingqinamba zesabelomali, izidingo zokusebenza kahle kwamandla, nezinhlelo zesikhathi eside zokunwetshwa. I-DDR4 inikeza ubuchwepheshe obuvuthiwe obunokwethenjelwa okuqinisekisiwe nezindleko eziphansi, kuyilapho i-DDR5 inikeza ububanzi be-bandwidth obuphakeme nezinzuzo ezivikela ikusasa kodwa ngokutshalwa kwemali okuphezulu kokuqala.
Ubuchwepheshe be-NVDIMM buyiphazamisa kanjani ukusebenza nokwethenjelwa kwesicelo?
Ubuchwepheshe be-NVDIMM bunikeza izinzuzo ezinkulu zokusetshenziswa okudinga ukusebenza kahle kanye nokuqina kwedatha. Inciphisa izikhathi zokululama kwesistimu ngemva kokuhluleka kukagesi, inika amandla ukucutshungulwa okusheshayo kokuthengiselana, futhi ithuthukise ukuthembeka kwesistimu jikelele ngokugcina ubuqotho bedatha ngesikhathi sokuvalwa okungalindelekile.
Uyini umehluko ekusetshenzisweni kwamandla phakathi kwalezi zindlela zokukhumbula?
I-DDR5 isebenza ngovoltaji ozilungileyo kungeya i-DDR4 futhi inezici ezahlelekileyo zokuphatha amandla, engakwenzela ukuba ibe nemfihlakalo yamandla kumakhemikhali aphezulu. Izisombululo ze-NVDIMM mazingadinga ukuqaphela okwengeziwe kwamandla ngokusho kwazo izici zabo zokugcina, kodwa ukusetshenziswa kwalokho kubangelwa yindlela ethile yokusebenza nezimo zokusetshenziswa.
