Vim li cas peb thiaj xav tau ib lub tsev tshiab?
Los ntawm 2030, cov khoom siv hluav taws xob yuav siv 40% ntawm tag nrho cov zog tsim tawm hauv ntiaj teb. Kwv yees li 20% ntawm qhov ntim no yuav los ntawm IT sector thiab cov chaw khaws ntaub ntawv. Los ntawm Raws li European cov kws tshuaj ntsuam, cov chaw zov me nyuam twb "tshem tawm" 1,4% ntawm tag nrho cov hluav taws xob. Nws xav tias qhov no .
SSD cia siv ib feem tseem ceeb ntawm hluav taws xob. Nyob rau lub sijhawm txij li xyoo 2012 txog 2017, kev sib koom ntawm cov khoom siv hauv xeev hauv cov chaw khaws ntaub ntawv . Txawm hais tias SSDs siv peb lub zog tsawg dua () dua li HDD, cov nqi hluav taws xob tseem loj ntawm qhov ntsuas ntawm cov chaw zov me nyuam.
Txhawm rau txo qis kev siv hluav taws xob ntawm cov khoom siv hauv lub xeev cov ntaub ntawv, cov kws ua haujlwm ntawm MIT tau tsim ib qho tshiab SSD cia architecture. Nws yog hu ua LightStore thiab tso cai rau koj los txuas cov drives ncaj qha mus rau cov ntaub ntawv chaw network, hla kev cia cov servers. Los ntawm cov kws sau ntawv, lub kaw lus yuav txo cov nqi hluav taws xob los ntawm ib nrab.
Yuav ua li cas li no ua hauj lwm
LightStore yog lub khw muag khoom muaj txiaj ntsig flash uas qhia cov neeg siv thov kom tsav ua cov yuam sij. Tom qab ntawd lawv raug xa mus rau lub server, uas tso tawm cov ntaub ntawv cuam tshuam nrog tus yuam sij ntawd.
system built-in zog-npaum processor, DRAM thiab NAND nco. Nws yog tswj los ntawm tus maub los thiab software tshwj xeeb. Tus maub los yog lub luag haujlwm ua haujlwm nrog NAND arrays, thiab software yog lub luag haujlwm rau kev ua KV thov thiab khaws cov khub tseem ceeb. Lub software architecture yog tsim los ntawm lub hauv paus , uas yog siv nyob rau hauv ntau niaj hnub DBMSs.
Daim duab kos duab tuaj yeem sawv cev raws li hauv qab no:
Daim duab qhia txog cov ntsiab lus tseem ceeb ntawm LightStore. Ib pawg node ua haujlwm ntawm cov khub tseem ceeb. Daim ntawv thov servers txuas nrog lub system siv adapters. Lawv hloov cov neeg thov (xws li fread() los ntawm POSIX API) rau hauv KV thov. Lub architecture kuj muaj cais adapters rau , thaiv (raws li BUSE module) thiab cov ntaub ntawv khaws cia.
Thaum faib kev thov, lub adapter siv . Nws yog siv hauv tshuab xws li Redis lossis Swift. Siv tus yuam sij KV thov, lub adapter tsim kom muaj tus yuam sij hash uas nws tus nqi txheeb xyuas lub hom phiaj node.
Lub peev xwm ntawm LightStore pawg scales linearly - tsuas yog txuas ntxiv nodes rau lub network. Qee zaum, koj yuav tsum tau yuav cov keyboards tshiab. Txawm li cas los xij, cov neeg tsim khoom tau nruab txhua qhov ntawm qhov txuas ntxiv rau kev txuas NAND chips.
Architecture lub peev xwm
MIT engineers hais tias LightStore-raws li kev daws teeb meem muaj peev xwm ntawm 620 Mbps tshaj 10 Gigabit Ethernet. Ib lub node siv 10 W es tsis txhob 20 W li ib txwm (hauv SSD systems siv los ntawm cov chaw zov me nyuam hnub no). Tsis tas li ntawd, cov cuab yeej siv tau ib nrab ntawm qhov chaw.
Tam sim no cov neeg tsim khoom tau ua tiav qee yam. Piv txwv li, LightStore tsis tuaj yeem ua haujlwm nrog ntau cov lus nug thiab cov lus nug me me. Cov yam ntxwv no yuav raug ntxiv rau yav tom ntej, txij li LightStore siv LSM ntoo. Tsis tas li ntawd, lub kaw lus tseem muaj qhov txwv tsis pub hloov pauv - YCSB thiab thaiv cov khoom siv tau txais kev txhawb nqa. Yav tom ntej, LightStore yuav tuaj yeem ua cov lus nug SQL, thiab lwm yam.
Lwm yam kev txhim kho
Thaum lub caij ntuj sov xyoo 2018, Marvell, lub tuam txhab txhim kho kev cia khoom, tau qhia txog kab tshiab ntawm SSD tswj raws li AI systems. Cov neeg tsim khoom tau koom ua ke NVIDIA kev kawm sib sib zog nqus accelerators rau hauv cov txheej txheem tswj hwm rau cov chaw khaws ntaub ntawv thiab cov neeg siv khoom siv. Raws li qhov tshwm sim, lawv tau tsim ib qho kev tsim kho tus kheej uas siv hluav taws xob tsawg dua piv rau cov tswj hwm SSD classic. Lub tuam txhab cia siab tias lub kaw lus yuav pom daim ntawv thov hauv ntug kev suav, kev txheeb xyuas cov ntaub ntawv loj thiab IoT.
Western Digital Blue kab ntawm drives tsis ntev los no tau hloov kho. Thaum lub Plaub Hlis, cov neeg tsim tawm tau nthuav tawm cov kev daws teeb meem - WD Blue SSD raws li SanDisk thev naus laus zis, uas WD tau txais ib xyoos dhau los. Cov tshiab WD Blue SSDs muab kev ua tau zoo dua qub thiab kev siv hluav taws xob. Lub architecture yog tsim los ntawm lub hauv paus ntawm specification , uas muab kev nkag mus rau SSDs txuas nrog ntawm PCI Express.
Qhov kev qhia tshwj xeeb no txhim kho kev ua haujlwm ntawm SSD drives nrog ntau qhov kev thov ib txhij thiab ua kom ceev cov ntaub ntawv nkag. Tsis tas li ntawd, NVMe tso cai rau koj los ua tus qauv SSD interface - ntau dua rau cov tuam txhab kho vajtse rau kev txhim kho cov tsav tsheb tshwj xeeb, cov khoom sib txuas thiab cov qauv tsim.

Cov ntaub ntawv chaw SSD kev ua lag luam tab tom mus rau qhov yooj yim architecture, automation ntawm cov khoom khaws cia, thiab ua kom muaj zog ntxiv. Txoj kev loj hlob ntawm engineers los ntawm MIT daws qhov teeb meem tom kawg. Cov kws sau ntawv tias LightStore yuav dhau los ua tus qauv kev lag luam rau SSD cia hauv cov chaw khaws ntaub ntawv. Thiab peb tuaj yeem xav tias yav tom ntej tshiab, txawm tias muaj txiaj ntsig zoo dua qub yuav tshwm sim raws li nws.
