Uvavanyo Lwendlela
Ngokusekelwe kwiseti edumileyo yovavanyo , nangona kunjalo, abavavanyi benze uhlengahlengiso kuyo ukwenza imithwalo isondele kusetyenziso lokwenyani lwe-SSD yeshishini ngo-2019. Kwinkcazo yovavanyo ngalunye, siya kuqaphela ukuba yintoni kanye kanye eyatshintshwayo kwaye kutheni.
UVavanyo lokuSebenza kweNgeniso/Imveliso (IOPS)
Olu vavanyo lulinganisa i-IOPS yeesayizi ezahlukeneyo zebhloko (1024 KB, 128 KB, 64 KB, 32 KB, 16 KB, 8 KB, 4 KB, 0,5 KB) kunye nofikelelo olungacwangciswanga olunomlinganiselo owahlukeneyo wokufunda/wokufunda (100/0). , 95/5, 65/35, 50/50, 35/65, 5/95, 0/100). Iingcali zeTruesystems zisebenzise ezi parameters zovavanyo zilandelayo: i-threads ye-16 enobunzulu bomgca we-8. Kwangaxeshanye, ibhloko ye-0,5 KB (512 bytes) ayizange iqhutywe konke konke, kuba ubukhulu bayo buncinci kakhulu ukulayisha ngokugqithiseleyo iidrives.

Idatha yetheyibhile:
I-Kingston DC500M kuvavanyo lwe-IOPS
Idatha yetheyibhile:
Uvavanyo lwe-IOPS aluthethi ukuba ufikelele kwimowudi yokugcwalisa, ngoko kulula kakhulu ukuphumelela. Zombini iidrives ziqhube kakuhle kakhulu, zithobela ngokupheleleyo iinkcukacha ezixeliweyo zasefektri. Izifundo zovavanyo zibonise ukusebenza kakuhle kakhulu ekubhaleni kwiibhloko eziyi-4 KB: 70 kunye nama-88 amawaka e-IOPS. Oku kuhle, ngakumbi kwi-Kingston DC500R ejolise ekufundeni. Ngokubhekiselele kwimisebenzi yokufunda ngokwazo, ezi drives ze-SSD azigqithisi kuphela ixabiso lefektri yazo, kodwa ngokubanzi zisondela kwisilingi yokusebenza kojongano lwe-SATA.
Uvavanyo lobubanzi
Olu vavanyo luphonononga iziphumo ezilandelelanayo. Oko kukuthi, zombini iidrive ze-SSD zenza imisebenzi elandelelanayo yokufunda nokubhala kwi-1 MB kunye neebhloko ze-128 KB. Imisonto esi-8 enobunzulu bomgca we-16 ngomsonto ngamnye.
Kingston DC500R:
- 128 KB ulandelelwano ufundeka: 539,81 MB/s
- 128 KB ngokulandelelana ukubhala: 416,16 MB/s
- 1 MB ngokulandelelanayo ukufunda: 539,98 MB/s
- 1 MB ngokulandelelana ukubhala: 425,18 MB/s
Kingston DC500M:
- 128 KB ulandelelwano ufundeka: 539,27 MB/s
- 128 KB ngokulandelelana ukubhala: 518,97 MB/s
- 1 MB ngokulandelelanayo ukufunda: 539,44 MB/s
- 1 MB ngokulandelelana ukubhala: 518,48 MB/s
Kwaye apha sibona kwakhona ukuba isantya sokufunda ngokulandelelana kwe-SSD siye safikelela kumda wokuphuma kwi-interface ye-SATA 3. Ngokubanzi, ii-Kingston drives azibonisi naziphi na iingxaki ngokufunda ngokulandelelana.
Ukubhala ngokulandelelana kuncipha kancinci, okubonakala ngakumbi kwi-Kingston DC500R, eyeyeklasi yokufunda enzulu, oko kukuthi, yenzelwe ufundo olunzulu. Ke ngoko, iKingston DC500R kule nxalenye yovavanyo ivelise amaxabiso aphantsi nokuba kuchaziwe. Kodwa iingcali ze-Truesystems zikholelwa ukuba kwi-drive engenziwanga imithwalo enjalo konke konke (khumbula ukuba i-DC500R inomthombo we-0,5 DWPD), ezi 400-plus MB / s zisenokuthi zithathwe njengesiphumo esihle.
Uvavanyo lokubambezeleka
Njengoko sele siphawulile, olu lolona vavanyo lubalulekileyo kwiidrive zeshishini. Emva kwayo yonke loo nto, ingasetyenziselwa ukufumanisa ukuba zeziphi iingxaki ezivelayo ngexesha lokusetyenziswa kwexesha elide le-SSD. Uvavanyo oluqhelekileyo lweSNIA PTS lulinganisa umndilili kunye nobuninzi bexesha lokulibaziseka kwiibhloko ezahlukeneyo zeesayizi (8 KB, 4 KB, 0,5 KB) kunye nomlinganiselo wokufunda/ubhala (100/0, 65/35, 0/100) kubunzulu obuncinane bomgca (1 umsonto ngeQD=1). Nangona kunjalo, abahleli beTruesystems bagqibe kwelokuba bayiguqule ngokunzulu ukuze bafumane amaxabiso akhoyo:
- Ibhloko engabandakanywanga 0,5 KB;
- Esikhundleni somthwalo owenziwe ngentambo kunye nomgca we-1 kunye ne-32, umthwalo uyahluka kwinani leentambo (1, 2, 4) kunye nobunzulu bomgca (1, 2, 4, 8, 16, 32);
- Endaweni yomlinganiselo wama-65/35, kusetyenziswa i-70/30 njengoko iyinyani;
- Ayingomndilili kunye nowona maxabiso aphezulu anikiweyo, kodwa neepesenti ezingama-99%, 99,9%;
- ngexabiso elikhethiweyo lenani leentambo, iigrafu ze-latency (99%, 99,9% kunye nexabiso eliphakathi) zicwangciswe malunga ne-IOPS yazo zonke iibhloko kunye nemilinganiselo yokufunda / yokubhala.
Idatha yayiyi-avareji kwimijikelo emine ye-25 ehlala imizuzwana ye-35 (i-5 yokufudumala + i-30-yesibini umthwalo) nganye. Kwiigrafu, abahleli beTruesystems bakhethe uluhlu lwamaxabiso anobunzulu bomgca ukusuka ku-1 ukuya ku-32 kunye nemisonto eyi-1-4. Oku kwenziwa ukwenzela ukuvavanya ukusebenza kwee-drives kuthathelwe ingqalelo i-latency, oko kukuthi, eyona nto ibonakalayo.
I-avareji yeemetriki zokulinda:
Le grafu ibonisa ngokucacileyo umahluko phakathi kwe-DC500R kunye ne-DC500M. I-Kingston DC500R yenzelwe ukusebenza ngokunzulu, ngoko ke inani lemisebenzi yokubhala ayinyuki ngokunyuka komthwalo, okushiyekileyo kwi-25.
Ukuba ujonga umthwalo odibeneyo (i-70% ibhala kunye ne-30% ifunde), umahluko phakathi kwe-DC500R kunye ne-DC500M nayo ihlala ibonakala. Ukuba sithatha umthwalo ohambelana ne-latency ye-microseconds ye-400, sinokubona ukuba i-DC500M yenjongo jikelele inomsebenzi ophindwe kathathu. Oku kukwayinto yendalo kwaye ivela kwiimpawu zokuqhuba.
Iinkcukacha ezinomdla kukuba i-DC500M igqwesa i-DC500R nakwi-100% efundwayo, ihambisa i-latency ephantsi kwisixa esifanayo se-IOPS. Umahluko uncinci, kodwa unomdla kakhulu.
99% latency percentile:
99.9% latency percentile:
Ukusebenzisa ezi grafu, iingcali zeTruesystems zihlolisise ukuthembeka kweempawu ezibhengeziweyo ze-QoS latency. Iinkcukacha zibonise u-0,5 ms efundiweyo kunye no-2 ms bhala kwibhloko ye-4 KB enomgca obunzulu obuyi-1. Siyazingca ukunika ingxelo yokuba la manani aqinisekisiwe, kunye nomda omkhulu. Okubangela umdla, ukulibaziseka kokufunda okuncinci (280-290 ΞΌs ye-DC500R kunye ne-250-260 ΞΌs ye-DC500M) ayiphunyezwanga nge-QD=1, kodwa nge-2-4.
I-latency yokubhala kwi-QD = i-1 yayiyi-50 ΞΌs (i-latency ephantsi enjalo ifunyenwe ngenxa yokuba kumthwalo ophantsi i-cache ye-drive iqinisekisiwe ukuba ibe nexesha lokukhulula, kwaye sihlala sibona ukulibaziseka xa sibhalela kwi-cache). Eli nani lingaphantsi ngokuphindwe ngama-40 kunexabiso elichaziweyo!
Uvavanyo lokuSebenza oluqhubekayo
Olunye uvavanyo oluyinyani kakhulu oluvavanya utshintsho lokusebenza (i-IOPS kunye ne-latency) ngexesha lomsebenzi omde. Imeko yokusebenza kukurekhodwa okungacwangciswanga kwiibhloko ezi-4 KB kangangemizuzu engama-600. Ingongoma yolu vavanyo kukuba phantsi komthwalo onjalo, i-SSD drive ingena kwimodi yokuzalisa, xa umlawuli eqhuba ngokuqhubekayo ekuqokeleleni inkunkuma ukuze alungiselele iibhloko zememori mahhala zokubhala. Oko kukuthi, le yeyona ndlela idinayo - kanye ukuba yeyiphi i-SSD yodidi lweshishini efunyenwe kwiiseva zokwenyani ezijongene nazo.
Ngokusekwe kwiziphumo zovavanyo, iTruesystems ifumene ezi zalathisi zokusebenza zilandelayo:
Esona siphumo siphambili sale nxalenye yovavanyo: zombini i-Kingston DC500R kunye ne-Kingston DC500M ekusebenzeni kokwenyani idlula amaxabiso abo emveliso. Xa iibhloko ezilungiselelwe ziphela, imodi yokugcwalisa iqala, i-Kingston DC500R ihlala kwi-22 IOPS (endaweni ye-000 IOPS). I-Kingston DC20M ihlala kuluhlu lwe-000-500, nangona iprofayili ye-drive ithi i-77 IOPS. Olu vavanyo lubonisa ngokucacileyo umahluko phakathi kwee-drive: ukuba inkqubo yokusebenza ye-drive ibandakanya umlinganiselo ophezulu wemisebenzi yokubhala, i-Kingston DC78M ijika ibe ngaphezu kwamaxesha amathathu emveliso (sikhumbula kwakhona ukuba i-DC000M yabonisa ukubambezeleka okungcono kwimisebenzi yokufunda. ).
Ukubambezeleka ngexesha lemisebenzi eqhubekayo yokubhala icwangciswe kule grafu ilandelayo. I-Medin, i-99%, i-99,9% kunye ne-99,99% yeepesenti.
Siyabona ukuba i-latency yazo zombini iidrives iyanda ngokulingana nokuncipha kokusebenza, ngaphandle kokuntywila okubukhali okanye iincopho ezingaqondakaliyo. Oku kuhle kakhulu, kuba ukuqikelelwa koko kanye kulindelekileyo kwiidrive zeshishini. Iingcali zeTruesystems zigxininisa ukuba uvavanyo lwenzeke kwimisonto esi-8 enobunzulu bomgca we-16 ngomsonto ngamnye, ngoko ayingowona maxabiso abalulekileyo, kodwa amandla. Xa bevavanya i-DC400, kukho ukulibaziseka okukhulu kolu vavanyo ngenxa yokusebenza komlawuli, kodwa kule grafu i-Kingston DC500R kunye ne-Kingston DC500M ayinazo iingxaki ezinjalo.
Layisha ukusasazwa kweLatency
Njengebhonasi, abahleli beTruesystems baqhube iKingston DC500R kunye neKingston DC500M ngovavanyo olulula lweNombolo ye-13 yeSNIA SSS PTS 2.0.1. Ukusasazwa kokulibaziseka phantsi komthwalo kwaphononongwa ngendlela yepateni ekhethekileyo ye-CBW:
Ubungakanani bebhloko:
Ukuhanjiswa komthwalo kuwo wonke umthamo wokugcina:
Umlinganiselo wokufunda/ubhala: 60/40%.
Emva kokucima okukhuselekileyo kunye nokulayishwa kwangaphambili, abahloli baqhube i-10 60-yesibini imijikelo yovavanyo oluphambili lokubala intambo ye-1-4 kunye nobunzulu bomgca we-1-32. Ngokusekwe kwiziphumo, i-histogram yokuhanjiswa kwamaxabiso ukusuka kwimijikelo ehambelana nomsebenzi ophakathi (IOPS) yakhiwa. Kuzo zombini iidrive iphunyezwe ngomsonto omnye ngobunzulu bomgca we-4.
Ngenxa yoko, la maxabiso alandelayo afunyenwe:
DC500R: 17949 IOPS kwi-594 Β΅s latency
DC500M: 18880 IOPS kwi448 Β΅s.
Ukusasazwa kweLatency kwahlalutywa ngokwahlukeneyo ukuze kufundwe nokubhala.
isiphelo
Abahleli beTruesystems bafikelela kwisigqibo sokuba ukusebenza kovavanyo lweKingston DC500R kunye neKingston DC500M kucaciswa ngokucacileyo njengento elungileyo. I-Kingston DC500R ihlangabezana kakuhle kakhulu nemisebenzi yokufunda, kwaye inokucetyiswa njengezixhobo zobungcali kwimisebenzi ehambelanayo. Kwimithwalo exubeneyo kwaye xa kufuneka amandla amaninzi, iTruesystems icebisa iKingston DC500M. Olu papasho lukwaphawula amaxabiso anomtsalane kuwo wonke umgca wemodeli ye-Kingston corporate drives kwaye uyavuma ukuba utshintsho lwe-TLC 3D-NAND luncede ngokwenene ukunciphisa ixabiso ngaphandle kokulahlekelwa ngumgangatho. Iingcali zeTruesystems ziphinde zathanda inqanaba eliphezulu lenkxaso yobugcisa yaseKingston kunye newaranti yeminyaka emihlanu yeDC500 yothotho lweedrive.
