Latency test
Sezvatatoona, uyu ndiwo muyedzo wakanyanya kukosha wekutyaira mabhizinesi. Mushure mezvose, inogona kushandiswa kuona kuti ndeapi matambudziko anomuka panguva yekushandiswa kwenguva refu kwezuva nezuva kweSSD drive. Iyo yakajairwa SNIA PTS bvunzo inoyera avhareji uye yakanyanya latency yeakasiyana block saizi (8 KB, 4 KB, 0,5 KB) uye kuverenga/kunyora reshiyo (100/0, 65/35, 0/100) pakudzika kwemutsetse (1 shinda ine QD=1). Nekudaro, vapepeti veTruesystems vakafunga kuigadzirisa zvakanyanya kuti iwane humwe humbowo hwechokwadi:
- Kusabatanidzwa block 0,5 KB;
- Panzvimbo pemutoro mumwe chete-tambo ine mitsara 1 uye 32, mutoro unosiyana muhuwandu hwetambo (1, 2, 4) uye kudzika kwemutsara (1, 2, 4, 8, 16, 32);
- Panzvimbo yereshiyo ye65/35, 70/30 inoshandiswa sezvo iri yechokwadi;
- Kwete chete avhareji uye yakanyanya kukosha inopihwa, asiwo percentiles e99%, 99,9%;
- nokuda kwekukosha kwakasarudzwa kwenhamba yeshinda, magirafu e latency (99%, 99,9% uye avhareji kukosha) anorongerwa IOPS yezvivharo zvose uye kuverenga / kunyora reshiyo.
Iyo data yakaverengerwa pamusoro pe ina ye25 kutenderera inogara 35 masekonzi (5 kudziya-up + 30-sekondi mutoro) imwe neimwe. Kune magirafu, iwo eTruesystems edhita akasarudza nhevedzano yehunhu ine mutsara wakadzika kubva 1 kusvika 32 ine 1-4 shinda. Izvi zvakaitwa kuitira kuongorora mashandiro edhiraivha uchifunga nezve latency, ndiko kuti, chiratidzo chechokwadi.
Avhareji yekunonoka metrics:
Iyi girafu inoratidza zvakajeka musiyano pakati peDC500R neDC500M. Kingston DC500R yakagadzirirwa kuverenga kwakanyanya, saka huwandu hwekunyora mashandiro hahuwedzere nekuwedzera mutoro, uchisara pamakumi maviri neshanu.
Kana iwe ukatarisa mutoro wakavhenganiswa (70% kunyora uye 30% kuverenga), musiyano pakati peDC500R neDC500M unoramba uchionekwa. Kana tikatora mutoro unoenderana ne latency ye400 microseconds, tinogona kuona kuti iyo general-chinangwa DC500M ine katatu kuita. Izvi zvakare zvakajairika uye zvinobva kune hunhu hwemadhiraivha.
Chinhu chinonakidza ndechekuti iyo DC500M inokunda iyo DC500R kunyangwe pa100% yakaverengwa, ichiunza yakaderera latency yehuwandu hwakafanana hweIOPS. Musiyano wacho muduku, asi unofadza zvikuru.

99.9% latency percentile:
Uchishandisa aya magirafu, Truesystems nyanzvi dzakatarisa kuvimbika kweakaziviswa maitiro eQoS latency. Zvinyorwa zvakaratidza 0,5 ms kuverenga uye 2 ms kunyora kune 4 KB block ine mutsara wakadzika we 1. Tinodada kuzivisa kuti nhamba idzi dzakasimbiswa, uye nemuganhu mukuru. Sezvineiwo, kunonoka kuverenga kushoma (280β290 ΞΌs yeDC500R uye 250β260 ΞΌs yeDC500M) inowanikwa kwete neQD=1, asi ne2β4.
Iyo yekunyora latency paQD = 1 yaive 50 ΞΌs (yakadaro yakaderera latency inowanikwa nekuda kwekuti pakuremerwa kwakadzika dhiraivha cache inovimbiswa kuve nenguva yekusunungura, uye isu tinogara tichiona kunonoka pakunyorera kune cache). Nhamba iyi yakaderera neka40 pane yakaziviswa kukosha!
Kuenderera Kwekuita Muedzo
Imwe bvunzo yechokwadi inoongorora shanduko yekushanda (IOPS uye latency) panguva yebasa rakasimba. Mamiriro ekushanda ndeyekurekodha zvisina kujairika mu4 KB mabhuroko kwemaminetsi mazana matanhatu. Pfungwa yeiyi bvunzo ndeyokuti pasi pemutoro wakadaro, iyo SSD drive inopinda mune saturation modhi, apo mutongi anoramba achibatikana mukuunganidza marara kugadzirira ndangariro mabhuraki emahara ekunyora. Ndokunge, iyi ndiyo inonyanya kunetesa modhi - chaizvo izvo bhizinesi-kirasi SSDs inowanikwa mumaseva chaiwo akatarisana.
Zvichienderana nemhedzisiro yebvunzo, Truesystems yakagamuchira zvinotevera kuita zviratidzo:
Mhedzisiro huru yechikamu ichi chebvunzo: zvese Kingston DC500R uye Kingston DC500M mukushanda chaiko inodarika yavo yega fekitori tsika. Kana zvidhinha zvakagadzirirwa zvinopera uye saturation mode inotanga, iyo Kingston DC500R inoramba iri pa22 IOPS (panzvimbo ye000 IOPS). Kingston DC20M inogara muhuwandu hwe 000-500, kunyange iyo drive profile inotaura 77 IOPS. Muedzo uyu unoratidzawo mutsauko uripo pakati pemadhiraivha: kana dhiraivha yekushanda ichibatanidza chikamu chepamusoro chekunyora mashandiro, iyo Kingston DC78M inoshanduka kuve yakapetwa katatu kubereka kubereka (isu tinorangarira zvakare kuti iyo DC000M yakaratidza zvirinani latency mukuverenga mashandiro. )
Latencies panguva yekuenderera kwekunyora mashandiro anorongwa mugirafu rinotevera. Median, 99%, 99,9% uye 99,99% percentiles.
Isu tinoona kuti latency yemadhiraivha ese ari maviri anowedzera zvichienderana nekudzikira kwekuita, pasina kupinza kwakapinza kana mapikisi asingatsananguriki.
