Ukuqala konyaka omusha kanye neshumi leminyaka elisha yisikhathi esihle sokuthatha isitoko futhi uhlole ubuchwepheshe obubalulekile kanye nezitayela zokugcina ezizoba nathi ezinyangeni ezizayo.
Sekuvele kusobala ukuthi ukufika kanye nokuba khona kwendawo yonke ye-Intanethi Yezinto (IoT), ubuhlakani bokufakelwa (AI) kanye nobuchwepheshe obuhlakaniphile sekuqondwe kabanzi, futhi ukuxhumana kwenethiwekhi namandla ekhompyutha azodingeka ukuze kusebenze zonke lezi zixazululo. okuxoxwa ngakho ngenkuthalo. Kodwa akufanele sikhohlwe ukuthi isici sesithathu, okungukuthi, okusho ukuthi, ngemuva kwezigcawu zokuqaliswa kwalezi zindlela ezintsha, nazo zithuthuka ngenkuthalo. Imayelana nokugcinwa kwedatha. Ingqalasizinda yokugcina esebenzayo nesebenzayo iwukhiye empumelelweni nempilo ende yenkampani, futhi ukukala kubalulekile ukuze wenze imali futhi wandise ukusetshenziswa kwedatha.
Ukwandisa ukuminyana okurekhodiwe kumadrayivu e-HDD, kokubili agcwele umoya esintu kanye nagcwaliswe nge-helium, kusho ukuthi ama-HDD esimanje kakhulu azoba namandla afinyelela ku-16 TB, kuyilapho amadrayivu e-HDD eyi-18 TB erekhodwa ngokwendabuko kazibuthe (CMR) kanye ne-20 TB. wokuqoshwa kukazibuthe we-tiled (SMR) okwamanje isahlolwa futhi izofika emakethe ngokuhamba kwesikhathi kulo nyaka. Ukwamukelwa kwe-SMR kulindeleke ukuthi kukhule ngokuphawulekayo eminyakeni emihlanu ezayo, okuvula indlela yokusabalalisa umthwalo womsebenzi osebenza kahle kakhulu kanye nezindlela ezintsha ze-Zoned Storage. Esikalini, ukwandisa ukuminyana kokurekhoda kubalulekile ekuletheni umthamo owengeziwe ngezindleko eziphelele zobunikazi (TCO), futhi ukuvela okuqhubekayo kwe-SMR kuzosekela lokhu. Ngesikhathi esifanayo, izinzuzo ezilethwa ubuchwepheshe be-flash emisebenzini efana ne-analytics ne-AI zenze izinhlelo zokugcina zonke ze-flash zanda kakhulu. Ukuthuthukiswa okuqhubekayo kobuchwepheshe benkumbulo ye-3D NAND ye-flash kuqhubezela phambili kwandisa ukuminyana futhi kunciphisa usayizi womzimba ngokusebenzisa ukunqwabelana kongqimba okume mpo kanye nokukala okuvundlile kuyo yonke i-wafer, okuhambisana nokwanda kwenani lamabhithi.
Amandla okushayela ayinhloko, ngaphandle kwawo angeke akwazi ukukhulula ngokugcwele amandla aphelele enkumbulo ye-flash kuma-SSD, uguquko olusuka ku-SATA luye ku-NVMe (Non-Volatile Memory Express). Isetshenziselwa ukufinyelela amaseva, okokusebenza kwesitoreji, nezindwangu zokugcina inethiwekhi, le phrothokholi esebenza kahle inciphisa ngokumangalisayo ukubambezeleka futhi isheshisa imisebenzi yohlelo lokusebenza.
Kepha ake sidlulele ngale kokuqanjwa kabusha emkhakheni we-HDD, i-SDD kanye ne-flash futhi sihlaziye amanye amathrendi ambalwa emhlabeni wonke, ngokubona kwethu, azonquma ukuthuthuka kwemboni yezokugcina ngo-2020 nangale kwalokho.
Inani lezikhungo zedatha yendawo lizokhula, kuzovela izakhiwo ezintsha
Nakuba ijubane lokuthuthela emafini linganciphisi, kunezici ezimbili ezisekela ukukhula okuqhubekayo kwezikhungo zedatha ezisendaweni (noma ezincane). Okokuqala, izimfuneko zokulawula ezintsha zokugcinwa kwedatha zisaku-ajenda. Amazwe amaningi ashaya imithetho yokugcinwa kwedatha, okuphoqa izinkampani ukuthi zigcine idatha iseduze nezifuba zazo ukuze zihlole kahle futhi zinciphise ubungozi obungaba khona obuhlobene nokugcina ukuvikeleka nobumfihlo bedatha abayiphethe. Okwesibili, ukubuyiswa kwamafu kuyabonwa. Izinkampani ezinkulu zivame ukuba nedatha yazo futhi, ngokuqashisa ifu, zinganciphisa izindleko futhi zilawule imingcele ehlukahlukene ngokubona kwazo, okuhlanganisa ukuphepha, ukubambezeleka nokufinyelela kwedatha; Le ndlela iholela ekwandeni kwesidingo samasistimu okugcina asendaweni.
Ukwengeza, izakhiwo ezintsha zesikhungo sedatha zizovela ukuze zibambe umthamo ohlale ukhula kanye nezinhlobonhlobo zedatha. Esikhathini se-zettabyte, ukwakhiwa kwengqalasizinda yokugcina kuyodingeka kushintshe njengoba usayizi nobunkimbinkimbi bemithwalo yemisebenzi, izinhlelo zokusebenza, kanye nedathasethi ye-AI/IoT yanda. Izakhiwo ezintsha ezinengqondo zizoba namazinga amaningana e-DCS, elungiselelwe imisebenzi eyahlukene, ngaphezu kwalokho, indlela yesofthiwe yohlelo izoshintsha. Uhlelo lwe-Zoned Storage's open source zoned storage luzosiza amakhasimende ukuthi avule amandla aphelele okuphathwa kwe-block block kuwo womabili ama-SMR HDD nama-ZNS SSD ukuze enze imisebenzi elandelanayo nebuswayo. Le ndlela ehlanganisiwe ikuvumela ukuthi uphathe idatha ye-serialized ngokwemvelo esikalini futhi ulethe ukusebenza okubikezelwayo.
Ukumiswa Kwe-AI Kokusetshenziswa Kalula Komphetho
Izibalo ngokungangabazeki ziyinzuzo enhle yokuncintisana, kodwa umthamo wedatha eqoqwa yizinkampani futhi izicubungule ukuze uthole imininingwane miningi kakhulu. Ngakho-ke manje, emhlabeni omusha lapho yonke into ixhunywe kuyo yonke into, imithwalo ethile yemisebenzi iya onqenqemeni, idala isidingo sokufundisa lezi ziphetho ezincane ukusebenzisa nokuhlaziya amanani edatha akhula njalo. Ngenxa yobuncane bamadivayisi anjalo kanye nesidingo sokuwethula ngokushesha kusevisi, azothuthukela ekumisweni okukhulu nokuhambisana.
Amadivayisi edatha kulindeleke ukuthi aqoqwe, futhi ukusungulwa kwemidiya nezindwangu kulindeleke ukuthi kusheshise kunokuba kwehle
Ukukhula okuqhubekayo kwe-exabyte kwezinhlelo zokusebenza ezibuswa ukufundwa esikhungweni sedatha kuzoqhubeka futhi kuzoqhuba izimfuno ezintsha ekusebenzeni, umthamo kanye nokuphumelela kwezindleko zezigaba zokugcina njengoba izinkampani ziya ngokuya zihlukanisa izinsizakalo ezilethwa ingqalasizinda yazo yokugcina. Ukuze kuhlangatshezwane nalezi zidingo, izakhiwo zesikhungo sedatha zizoya ngokuya zibheke kumodeli yesitoreji enikeza amandla okunikeza nokufinyelela idatha phezu kwendwangu, ngenkundla yokugcina eyisisekelo nezinto zikagesi ezisekela uchungechunge lwezivumelwano zamaleveli wesevisi (ama-SLA) ukuze kuhlangatshezwane nazo. izimfuneko ezithile zohlelo lokusebenza. Silindele ukwanda kokwamukelwa kwe-SSD ukuze kucutshungulwe idatha ngokushesha, kuyilapho siqhubeka nokubona isidingo esiqhubekayo sama-exabyte esitoreji esingabizi kakhulu, esinokwehla esizoqhubeka nokusekela ukukhula okuqinile kwemikhumbi ye-HDD yebhizinisi ukuze kugcinwe idatha enkulu.
Izimboni njengesixazululo sokuhlanganisa isitoreji esabiwe
Njengoba umthamo wedatha uqhubeka nokukhula ngamandla, imithwalo yemisebenzi kanye nezidingo zengqalasizinda ye-IT ziqhubeka nokuhlukahluka, izinkampani kufanele zinikeze amakhasimende ngokushesha, izixazululo ezivumelana nezimo kuyilapho zinciphisa isikhathi sokumaketha. Izindwangu ze-Ethernet ziba "i-backplane yomhlaba wonke" yesikhungo sedatha, ukwabelana okuhlanganisayo, ukuhlinzeka, nezinqubo zokuphatha ngenkathi kulinganiswa ukuze kuhlangatshezwane nezidingo zokuhlukahluka okwanda njalo kwezinhlelo zokusebenza nemithwalo yomsebenzi. I-Composable Infrastructure iyindlela entsha yokwakha esebenzisa i-NVMe-over-Fabric ukuze ithuthukise ngendlela emangalisayo ukusetshenziswa, ukusebenza, nokuguquguquka kwekhompyutha nokugcinwa esikhungweni sedatha. Ivumela isitoreji ukuthi sihlukaniswe ezinhlelweni zekhompuyutha ngokuvumela izinhlelo zokusebenza ukuthi zabelane ngesitoreji esivamile, lapho idatha ingabiwa kalula phakathi kwezinhlelo zokusebenza kanye nomthamo odingekayo ungabelwa uhlelo lokusebenza ngamandla, kungakhathaliseki indawo. Ngo-2020, izixazululo zesitoreji ezihlanganisiwe, ezihlukanisiwe ezifinyelela ngempumelelo phezu kwezindwangu ze-Ethernet futhi zivule amandla aphelele okusebenza kwamadivayisi we-NVMe ezinhlobonhlobo zezinhlelo zokusebenza zesikhungo sedatha zizosakazeka kakhulu.
Ama-HDD esikhungo sedatha azoqhubeka nokuvela ngesivinini esisheshayo
Naphezu kweqiniso lokuthi iminyaka eminingana manje abaningi bebebikezela ukwehla kokuthandwa kwamadrayivu e-HDD, okwamanje akukho ukushintshwa okwanele kwama-HDD ezinkampani, ngoba abaqhubeki nje nokwanelisa izidingo ezihlobene nokukhula kwevolumu yedatha. , kodwa futhi ibonise ukusebenza kahle kwezindleko ngokuya ngezindleko eziphelele zobunikazi (TCO) lapho kulinganiswa izikhungo zedatha ye-hyperscale. Njengoba inkampani ye-analytics iphawula embikweni wakhe (I-Cloud, i-Hyperscale, ne-Enterprise Storage Service), amadrayivu e-HDD ezinkampani afunwa kakhulu ngokungaguquki: ama-exabyte wamadivayisi azokwethulwa emakethe ngezidingo zebhizinisi, futhi ukukhula konyaka phakathi neminyaka emihlanu yekhalenda kusuka ku-2018 kuya ku-2023 kuzoba ngama-36%. Ngaphezu kwalokho, ngokusho , ngo-2023, ama-Zbytes angu-103 edatha azokhiqizwa, ama-Zbyte angu-12 azogcinwa, lapho u-60% wawo uzothunyelwa kuzikhungo zedatha eziyinhloko/zomphetho. Iqhutshwa ukukhula okungagculiseki kwedatha ekhiqizwa kokubili abantu nemishini, lobu buchwepheshe obuyisisekelo buzophonswa inselelo ngamasu amasha okuhlelwa kwedatha, ukuminyana okuphezulu kokuqopha, ukusungulwa kwemishini, ukugcinwa kwedatha okuhlakaniphile, kanye nokusungulwa kwezinto ezintsha. Konke lokhu kuzoholela ekukhuleni komthamo kanye nezindleko eziphelele zobunikazi (i-TCO) lapho kulinganiswa esikhathini esizayo esibonakalayo.
Uma kubhekwa indima yabo ebalulekile ekugcineni nasekulawuleni idatha ebalulekile yenkampani, i-HDD nobuchwepheshe be-flash kuzohlala kungenye yezinsika eziyisisekelo zebhizinisi eliphumelelayo nelivikelekile, kungakhathaliseki ukuthi ingakanani inhlangano, uhlobo lwayo noma imboni esebenza kuyo. Ukutshala imali kwingqalasizinda yokugcinwa kwedatha ebanzi kuzovumela izinkampani ukuthi ziqinise isikhundla sazo futhi, ngokuhamba kwesikhathi, zikwazi ukubhekana kalula nokwanda kwevolumu yedatha, ngaphandle kokukhathazeka ngokuthi uhlelo olulakhile ngeke lubhekane nomthwalo ohambisana nawo. ukuqaliswa kwezinqubo zebhizinisi zesimanje nezisezingeni eliphezulu.
