Indlela yokuhlola
Ngokusekelwe kusethi yokuhlola edumile , nokho, abahloli benza izinguquko kuyo ukuze benze imithwalo isondele ekusetshenzisweni kwangempela kwama-SSD ezinkampani ngo-2019. Encazelweni yokuhlolwa ngakunye, sizoqaphela ukuthi yini ngempela eyashintshwa nokuthi kungani.
Ukuhlolwa Kokusebenza Kokokufaka/Okukhiphayo (IOPS)
Lokhu kuhlola kukala i-IOPS yosayizi abahlukene bebhulokhi (1024 KB, 128 KB, 64 KB, 32 KB, 16 KB, 8 KB, 4 KB, 0,5 KB) nokufinyelela okungahleliwe okunezilinganiso ezihlukile zokufunda/zokufunda. irekhodi (100/0 , 95/5, 65/35, 50/50, 35/65, 5/95, 0/100). Ochwepheshe be-Truesystems basebenzise amapharamitha wokuhlola alandelayo: Imicu engu-16 enomugqa wokujula okungu-8. Ngesikhathi esifanayo, ibhulokhi engu-0,5 KB (512 bytes) ayizange isetshenziswe nhlobo, njengoba usayizi wayo mncane kakhulu ukuthi ungalayisha ngokujulile amadrayivu.

Idatha yethebula:
I-Kingston DC500M ekuhlolweni kwe-IOPS
Idatha yethebula:
Ukuhlolwa kwe-IOPS akusho ukufinyelela kumodi yokugcwaliswa kwesikhala, ngakho-ke kulula ukudlula. Womabili amadrayivu asebenze kahle kakhulu, athobelana ngokuphelele nemininingwane yefekthri eshiwo. Izifundo zokuhlolwa zibonise ukusebenza okuhle kakhulu ekubhaleni kumabhulokhi angu-4 KB: 70 kanye nezinkulungwane ezingama-IOPS ezingama-88. Lokhu kuhle, ikakhulukazi ku-Kingston DC500R egxile ekufundeni. Ngokuqondene nokusebenza okufundwayo ngokwazo, lezi zishayeli ze-SSD azigcini nje ngokudlula amanani efekthri, kodwa futhi ngokuvamile zisondela ekulingeni kokusebenza kwesixhumi esibonakalayo se-SATA.
Ukuhlolwa Komkhawulokudonsa
Lokhu kuhlola kuhlola ukuphuma okulandelanayo. Okusho ukuthi, womabili amadrayivu e-SSD enza imisebenzi elandelanayo yokufunda nokubhala kumabhulokhi angu-1 MB no-128 KB. Imicu engu-8 enomugqa wokujula okungu-16 intambo ngayinye.
I-Kingston DC500R:
- 128 KB ukulandelana kufundwe: 539,81 MB/s
- 128 KB ukubhala ngokulandelana: 416,16 MB/s
- 1 MB ukufunda okulandelanayo: 539,98 MB/s
- 1 MB ukubhala ngokulandelana: 425,18 MB/s
I-Kingston DC500M:
- 128 KB ukulandelana kufundwe: 539,27 MB/s
- 128 KB ukubhala ngokulandelana: 518,97 MB/s
- 1 MB ukufunda okulandelanayo: 539,44 MB/s
- 1 MB ukubhala ngokulandelana: 518,48 MB/s
Futhi lapha sibona futhi ukuthi isivinini sokufunda esilandelanayo se-SSD sifinyelele umkhawulo wokukhipha isikhombimsebenzisi se-SATA 3. Ngokuvamile, amadrayivu e-Kingston awabonisi izinkinga ngokufunda okulandelanayo.
Ukubhala okulandelanayo kubambezeleka kancane, okubonakala ikakhulukazi ku-Kingston DC500R, okungeyekilasi elifundwa kakhulu, okungukuthi, lenzelwe ukufundwa okujulile. Ngakho-ke, i-Kingston DC500R kule ngxenye yokuhlolwa ikhiqize amanani aphansi kakhulu kunalokho okushiwo. Kodwa ochwepheshe be-Truesystems bakholelwa ukuthi ngedrayivu engaklanyelwe imithwalo enjalo nhlobo (khumbula ukuthi i-DC500R inensiza engu-0,5 DWPD), lawa ma-400-plus MB/s asengabhekwa njengomphumela omuhle.
Ukuhlolwa kokubambezeleka
Njengoba sesiphawulile, lokhu ukuhlolwa okubaluleke kakhulu kokushayela kwebhizinisi. Phela, ingasetshenziswa ukunquma ukuthi yiziphi izinkinga eziphakama ngesikhathi sokusetshenziswa kwansuku zonke kwe-SSD drive. Ukuhlolwa okujwayelekile kwe-SNIA PTS kukala ukubambezeleka okumaphakathi nobukhulu bosayizi abahlukahlukene bebhulokhi (8 KB, 4 KB, 0,5 KB) kanye nezilinganiso zokufunda/ukubhala (100/0, 65/35, 0/100) ekujuleni komugqa (1) intambo ene-QD=1). Kodwa-ke, abahleli be-Truesystems banqume ukuyilungisa sina ukuze bathole amanani angokoqobo:
- Ibhulokhi ekhishiwe 0,5 KB;
- Esikhundleni somthwalo onentambo eyodwa nolayini 1 no-32, umthwalo uyahlukahluka ngenani lezintambo (1, 2, 4) nokujula komugqa (1, 2, 4, 8, 16, 32);
- Esikhundleni se-65/35 ratio, 70/30 isetshenziswa njengoba ingokoqobo;
- Akuwona kuphela amanani aphakathi nendawo aphezulu anikezwayo, kodwa futhi namaphesenti angama-99%, 99,9%;
- ngevelu ekhethiwe yenani lezintambo, amagrafu okubambezeleka (99%, 99,9% kanye nenani elimaphakathi) ahlelwa ngokumelene ne-IOPS yawo wonke amabhlogo kanye nezilinganiso zokufunda/zokubhala.
Idatha yalinganiselwa emizuliswaneni emine kwengu-25 ehlala imizuzwana engu-35 (ukufudumala okungu-5 + nomthwalo wamasekhondi angu-30) ngayinye. Kumagrafu, abahleli be-Truesystems bakhethe uchungechunge lwamanani anomugqa ojulile ukusuka ku-1 kuye ku-32 ngemicu engu-1β4. Lokhu kwenziwa ukuze kuhlolwe ukusebenza kokushayela kucatshangelwa ukubambezeleka, okungukuthi, inkomba engokoqobo kakhulu.
I-average latency metrics:
Le grafu ibonisa ngokucacile umehluko phakathi kwe-DC500R ne-DC500M. I-Kingston DC500R iklanyelwe ukusebenza kokufunda okujulile, ngakho-ke inani lemisebenzi yokubhala cishe alikhuli ngomthwalo okhulayo, osele ku-25.
Uma ubheka umthwalo oxubile (u-70% ubhale futhi u-30% ufundwe), umehluko phakathi kwe-DC500R ne-DC500M nawo uhlala ubonakala. Uma sithatha umthwalo ohambisana nokubambezeleka kwama-microseconds angu-400, singabona ukuthi i-DC500M yenhloso evamile inokuphinda kathathu ukusebenza. Lokhu nakho kungokwemvelo futhi kubangelwa izici zamadrayivu.
Imininingwane ethokozisayo ukuthi i-DC500M idlula i-DC500R ngisho nasekufundweni okungu-100%, iletha ukubambezeleka okuphansi ngenani elifanayo le-IOPS. Umehluko mncane, kodwa uthakazelisa kakhulu.
99% amaphesenti wokubambezeleka:
99.9% amaphesenti wokubambezeleka:
Besebenzisa lawa magrafu, ochwepheshe be-Truesystems bahlole ukwethembeka kwezici ezimenyezelwe ze-QoS latency. Ukucaciswa kukhonjiswe u-0,5 ms kufundiwe no-2 ms kubhala ibhulokhi engu-4 KB enomugqa wokushona ongu-1. Siyaziqhenya ukubika ukuthi lezi zibalo ziqinisekisiwe, futhi ngemajini enkulu. Kuyathakazelisa ukuthi ukulibaziseka okuncane kokufunda (280β290 ΞΌs kwe-DC500R kanye no-250β260 ΞΌs kwe-DC500M) akufinyelelwanga nge-QD=1, kodwa ngo-2β4.
Ukubambezeleka kokubhala ku-QD=1 bekungama-50 ΞΌs (ukubambezeleka okuphansi okunjalo kutholwa ngenxa yokuthi uma ulayisha kancane inqolobane yokushayela iqinisekisiwe ukuthi inesikhathi sokukhulula, futhi sihlala sibona ukubambezeleka lapho sibhalela inqolobane). Lesi sibalo singaphansi izikhathi ezingu-40 kunenani elishiwo!
Ukuhlolwa Kokusebenza Okuqhubekayo
Olunye uvivinyo olungokoqobo kakhulu oluhlola izinguquko zokusebenza (i-IOPS nokubambezeleka) phakathi nomsebenzi omude onzima. Isimo sokusebenza siwukuqoshwa okungahleliwe ngamabhulokhi angu-4 KB imizuzu engama-600. Iphuzu lalolu vivinyo liwukuthi ngaphansi komthwalo onjalo, idrayivu ye-SSD ingena kumodi yokugcwalisa, lapho isilawuli sisebenza ngokuqhubekayo ekuqoqweni kukadoti ukuze silungiselele amabhlogo wememori mahhala ukuze abhale. Okusho ukuthi, lena imodi ekhandla kakhulu - lokho kanye ama-SSD atholakala kumaseva wangempela abhekene nawo.
Ngokusekelwe emiphumeleni yokuhlolwa, i-Truesystems ithole izinkomba zokusebenza ezilandelayo:
Umphumela oyinhloko wale ngxenye yokuhlolwa: kokubili i-Kingston DC500R ne-Kingston DC500M ekusebenzeni kwangempela kudlula amanani embonini yawo. Lapho amabhulokhi alungisiwe ephela, imodi yokugcwalisa iqala, i-Kingston DC500R ihlala ku-22 IOPS (esikhundleni se-000 IOPS). I-Kingston DC20M ihlala kububanzi obungu-000-500, nakuba iphrofayela yokushayela ithi 77 IOPS. Lokhu kuhlola futhi kubonisa ngokucacile umehluko phakathi kwamadrayivu: uma inqubo yokusebenza yedrayivu ihilela ingxenye ephezulu yokusebenza kokubhala, i-Kingston DC78M iphuma ibe ngaphezu kokuphindwe kathathu ukukhiqiza (sikhumbula futhi ukuthi i-DC000M ibonise ukubambezeleka okungcono ekusebenzeni kokufunda. ).
Ukubambezeleka ngesikhathi semisebenzi yokubhala eqhubekayo kuhlelwa kugrafu elandelayo. I-Median, 99%, 99,9% kanye ne-99,99% yamaphesenti.
Siyabona ukuthi ukubambezeleka kwawo womabili amadrayivu kuyenyuka ngokulingana nokuncipha kokusebenza, ngaphandle kokucwiliswa okucijile noma ukuphakama okungachazeki. Lokhu kuhle kakhulu, njengoba ukubikezela kuyilokho kanye okulindelekile kumadrayivu ebhizinisi. Ochwepheshe be-Truesystems bagcizelela ukuthi ukuhlola kwenzeke emiculweni engu-8 ngokujula komugqa okungu-16 ngochungechunge ngalunye, ngakho akuwona amanani aphelele abalulekile, kodwa amandla. Lapho behlola i-DC400, kwaba nokubambezeleka okukhulu kulokhu kuhlolwa ngenxa yokusebenza kwesilawuli, kodwa kule grafu i-Kingston DC500R ne-Kingston DC500M ayinazo izinkinga ezinjalo.
Layisha Ukubambezeleka Ukusabalalisa
Njengebhonasi, abahleli be-Truesystems basebenzise i-Kingston DC500R ne-Kingston DC500M ngokuhlolwa okwenziwe lula No. 13 kokucaciswa kwe-SNIA SSS PTS 2.0.1. Ukusatshalaliswa kokubambezeleka ngaphansi komthwalo kwafundwa ngendlela yephethini ekhethekile ye-CBW:
Vimba osayizi:
Layisha ukusatshalaliswa kuwo wonke umthamo wesitoreji:
Isilinganiso sokufunda/sokubhala: 60/40%.
Ngemva kokusula okuvikelekile nokulayisha kuqala, abahloli bagijime imizuliswano eyi-10 60-yesekhondi yokuhlola okuyinhloko ngenani lentambo engu-1β4 kanye nokushona komugqa okungu-1β32. Ngokusekelwe emiphumeleni, kwakhiwa i-histogram yokusatshalaliswa kwamanani ukusuka emizuliswaneni ehambisana nokusebenza okumaphakathi (IOPS). Kuwo womabili amadrayivu kufezwe ngochungechunge olulodwa olunomugqa wokujula okungu-4.
Ngenxa yalokho, kutholwe amanani alandelayo:
I-DC500R: 17949 IOPS ku-594 Β΅s ukubambezeleka
I-DC500M: 18880 IOPS ku-448 Β΅s.
Ukusabalalisa kokubambezeleka kwahlaziywa ngokwehlukana ukuze kufundwe nokubhala.
isiphetho
Abahleli be-Truesystems bafinyelele esiphethweni sokuthi ukusebenza kokuhlolwa kwe-Kingston DC500R ne-Kingston DC500M kuhunyushwa ngokusobala njengokuhle. I-Kingston DC500R ibhekana kahle kakhulu nemisebenzi yokufunda, futhi inganconywa njengemishini yobungcweti yemisebenzi ehambisanayo. Ngemithwalo exubile nalapho kudingeka amandla engeziwe, i-Truesystems incoma i-Kingston DC500M. Ukushicilelwa kuphinde kuphawule izintengo ezikhangayo zawo wonke umugqa wemodeli yamadrayivu ezinkampani e-Kingston futhi iyavuma ukuthi ukushintshela ku-TLC 3D-NAND kusize ngempela ukwehlisa intengo ngaphandle kokulahlekelwa yikhwalithi. Ochwepheshe be-Truesystems baphinde bathanda izinga eliphezulu lokusekelwa kwe-Kingston lobuchwepheshe kanye newaranti yeminyaka emihlanu yochungechunge lwamadrayivu e-DC500.
