Zhizha muMoscow gore rino raive, kutaura chokwadi, kwete rakanaka kwazvo. Yakatanga kare kare uye nokukurumidza, havasi vose vaiva nenguva yekuita nayo, uye yakapera kare pakupera kwaJune. Naizvozvo, Huawei paakandikoka kuti ndiende kuChina, kuguta reChengdu, uko nzvimbo yavo yeRnD iripo, mushure mekutarisa mamiriro ekunze e +34 degrees mumumvuri, ndakabva ndabvuma. Mushure mezvose, handisisiri zera rimwe chete uye ndinoda kudziya mapfupa angu zvishoma. Asi ndinoda kuona kuti zvaikwanisika kudziya kwete mapfupa chete, asiwo mukati, nokuti purovhinzi yeSichuan, umo Chengdu iri chaizvo, inozivikanwa nokuda kwekuda zvokudya zvinonaka. Asi zvakadaro, iyi haisi bhurogi nezvekufamba, saka ngatidzokere kuchinangwa chikuru cherwendo rwedu - mutsara mutsva wekuchengetedza masisitimu - Huawei Dorado V6. Ichi chinyorwa chinokuzunguza iwe zvishoma kubva kare, nekuti... yakanyorwa pamberi pechiziviso chepamutemo, asi yakabudiswa chete mushure mekusunungurwa. Uye saka, nhasi tichanyatso tarisisa zvese zvinonakidza uye zvinonaka izvo Huawei akatigadzirira.
Pachave nemhando 5 mumutsara mutsva. Mamodheru ese kunze kwe3000V6 anogona kuve mune maviri mavhezheni - SAS uye NVMe. Sarudzo inotarisisa maratidziro emadhisiki aunogona kushandisa mune ino system, iyo Back-End ports uye nhamba yedhisiki madhiraivha aunogona kuisa muhurongwa. Kune NVMe, Palm-sized SSDs anoshandiswa, ayo akatetepa kupfuura ekare 2.5 β³ SAS SSDs uye anogona kuiswa muzvikamu makumi matatu nematanhatu. Mutsara mutsva ndeye Yese Flash uye hapana magadzirirwo ane disks.
Palm NVMe SSD
Sekuona kwangu, iyo Dorado 8000 uye 18000 inotaridzika semhando dzinonakidza. Ndiwo mamodheru aya andichatarisisa pakuongorora kwangu nhasi. Ini ndichacherechedza ipapo ipapo kuti nekuda kwemaitiro avo ekugadzira, junior dual-controller masisitimu ane zvivakwa zvakasiyana zvishoma, zvakasiyana neDorado 8000 uye 18000, saka hazvisi zvese zvandichataura nezvazvo nhasi zvinoshanda kune majunior modhi.
Chimwe chezvinhu zvikuru zvezvirongwa zvitsva kwaiva kushandiswa kwemachipisi akawanda, akagadzirwa mukati meimba, imwe neimwe inokubvumira kuti ugovere mutoro unonzwisisika kubva kumugadziri wepakati pekugadzirisa uye kuwedzera kushanda kune zvikamu zvakasiyana.
Mwoyo wehurongwa hutsva ndeyeKunpeng 920 processors, yakagadziridzwa paArM tekinoroji uye inogadzirwa naHuawei yakazvimiririra. Zvichienderana nemuenzaniso, huwandu hwemacores, frequency yavo uye nhamba yeakaisirwa processors mune yega yega controller inosiyana:
Huawei Dorado V6 8000 - 2CPU, 64 musimboti
Huawei Dorado V6 18000 - 4CPU, 48 musimboti
Huawei akagadzira iyi processor paArM architecture, uye sekuziva kwangu, pakutanga yakaronga kuiisa chete mumhando dzekare dzeDorado 8000 uye 18000, sezvanga zvagara zvakadaro nemamwe maV5 modhi, asi zvirango zvakagadzirisa pfungwa iyi. Ehe, ARM yakataurawo nezvekuramba kushanda pamwe neHuawei panguva yekumisikidzwa kwezvirango, asi pano mamiriro acho akasiyana pane neIntel. Huawei anogadzira aya machipisi akazvimirira, uye hapana zvirango zvinogona kumisa maitiro aya. Kupatsanura hukama neARM kunongotyisidzira kurasikirwa kwekuwana kune zvitsva zvinoitika. Nezvekuita, zvinokwanisika kutonga chete mushure mekuita bvunzo dzakazvimirira. Kunyange zvazvo ndakaona kuti 18000M IOPS yakabviswa sei kubva kuDorado 1 system pasina matambudziko, kusvikira ndazvidzokorora nemaoko angu muraki yangu, handingazvitendi. Asi pane chaizvo simba rakawanda muvatongi. Mhando dzechikuru dzakashongedzerwa ne4 controller, imwe neimwe iine 4 processors, ichipa huwandu hwe768 cores.
Asi ini ndichataura nezve macores kunyangwe gare gare, kana tatarisa magadzirirwo ehurongwa hutsva, asi ikozvino ngatidzokere kune imwe chip yakaiswa muhurongwa. Iyo chip inoita senge mhinduro inonakidza kwazvo (Sekunzwisisa kwangu, munun'una weAscend 910, iyo ichangobva kuratidzwa kuvanhu). Basa rayo nderekuongorora zvivharo zve data kupinda muhurongwa kuti uwedzere Read hit ratio. Zvakaoma kutaura kuti zvinozoita sei kubasa, nekuti... Nhasi inongoshanda zvinoenderana netemplate yakapihwa uye haina kugona kudzidza mune yakangwara mode. Kuonekwa kwehungwaru modhi inovimbiswa mune ramangwana firmware, ingangoita kutanga kwegore rinouya.
Ngatienderere mberi kune architecture. Huawei akaenderera mberi nekugadzira yayo Smart Matrix tekinoroji, iyo inoshandisa yakazara mesh nzira yekubatanidza zvikamu. Asi kana muV5 iyi yaingove yekuwana kubva kuvatongi kuenda kumadhisiki, ikozvino vatongi vese vane mukana kune ese madoko pane ese ari Kumashure-End uye Front-End.
Nekuda kweiyo nyowani microservice architecture, izvi zvakare zvinobvumira kuyera kuyera pakati pevanodzora vese, kunyangwe paine lun imwe chete. Iyo OS yeiyi mutsara wearrays yakagadziridzwa kubva pasi kumusoro, uye kwete kungogadziriswa kuitira kushandiswa kweFlash drive. Nekuda kwekuti vatongi vedu vese vanokwanisa kuwana zviteshi zvakafanana, kana pakaitika kutadza kwemutongi kana kutangazve, mugadziri haarasikirwe neimwe nzira kune yekuchengetedza sisitimu, uye nzira yekuchinja inoitwa padanho rekuchengetedza system. Nekudaro, kushandisa UltraPath pane iyo saiti haina kunyanya kudikanwa. Imwe "kuchengetedza" paunenge uchiisa sisitimu ndiyo nhamba diki yezvibatanidza zvinodikanwa. Uye kana ne "classical" nzira yevatongi vana tichada 4 links kubva kumafekitari maviri, ipapo munyaya yeHuawei kunyange 8 ichave yakakwana (ini handisi kutaura ikozvino pamusoro pekukwana kwekubuda kweimwe link).
Sezvakaita mushanduro yapfuura, cache yepasi rose ine mirroring inoshandiswa. Izvi zvinokutendera kuti urasikirwe nevatongi vaviri panguva imwe chete kana vatatu vanodzora zvakateerana pasina kukanganisa kuwanikwa. Asi zvakakosha kucherechedza kuti isu hatina kuona yakazara mutoro kuyera pakati pevakasara 3 controller muchiitiko chekutadza kumwe chete pademo stand. Mutoro wemutongi akakundikana wakatorwa zvachose nemumwe wevakasara. Zvinogoneka kuti nekuda kweizvi zvinodikanwa kurega iyo system ichishanda kwenguva yakareba mukugadziriswa uku. Chero zvazvingava, ini ndichatarisa izvi zvakadzama ndichishandisa yangu bvunzo.
Huawei arikuisa masisitimu matsva seEnd-to-End NVMe masisitimu, asi nhasi NVMeOF haisati yatsigirwa kumberi, chete FC, iSCSI kana NFS. Pakupera kweizvi kana kutanga kweinotevera, semamwe maficha, isu tinovimbiswa RoCE rutsigiro.
Masherufu akabatanidzwawo kune vanodzora vanoshandisa RoCE, uye pane imwe dhizaini yakabatana neizvi - kusavapo kwe "loopback" yekubatanidza masherufu, sezvaive zvakaita neSAS. Sekuona kwangu, ichi chichiri chidimbu chakakura kana iwe uri kuronga yakakura system. Ichokwadi ndechokuti masherufu ose akabatanidzwa mumutsara, uye kukundikana kweimwe yemasherufu kunoguma nekusasvikika kwakakwana kwevamwe vose vanoitevera. Muchiitiko ichi, kuti tive nechokwadi chekushivirira kukanganisa, tichafanirwa kubatanidza masherufu ose kune vatongi, izvo zvinosanganisira kuwedzera kwenhamba inodiwa ye backend ports muhurongwa.
Uye chimwe chinhu chakakodzera kutaurwa hachisi-chinokanganisa update (NDU). Sezvandambotaura pamusoro, Huawei aita nzira yekushandisa iyo OS yeDorado mutsara mutsva, izvi zvinokutendera kuti uvandudze uye utangezve masevhisi pasina chikonzero chekumisikidza zvachose mutongi. Zvakakodzera kutaura ipapo ipapo kuti zvimwe zvigadziriso zvichange zvine kernel zvigadziriso, uye mune iyi kesi, yekirasi reboot yevatongi dzimwe nguva ichiri kudikanwa panguva yekuvandudza, asi kwete nguva dzose. Izvi zvinoderedza kukanganisa kwekushanda uku pakugadzirwa kwegadziriro.
Mune yedu arsenal, akawanda akawanda arrays anobva kuNetApp. Naizvozvo, ndinofunga zvichave zvine musoro kana ndikaita kuenzanisa kudiki nemasisitimu andinofanira kushanda nawo zvakanyanya. Uku hakusi kuedza kuona kuti ndiani ari nani uye kuti ndiani akaipisisa kana kuti mavakirwo aani anonyanya kubatsira. Ini ndichaedza kungwarira uye pasina kunyanyisa kuenzanisa nzira mbiri dzakasiyana dzekugadzirisa dambudziko rimwe chete kubva kune vakasiyana vatengesi. Ehe, hongu, mune ino kesi tichafunga nezve Huawei masisitimu mu "dzidziso" uye ini zvakare ndichasiyana cherechedza iwo mapoinzi akarongwa kuti aitwe mune ramangwana firmware shanduro. Ndeapi mabhenefiti andinoona panguva ino:
- Nhamba yemadhiraivha eNVMe anotsigirwa. NetApp parizvino ine 288 yavo, nepo Huawei ine 1600-6400, zvichienderana nemuenzaniso. Panguva imwecheteyo, Huawei's Max inoshandisika kugona ndeye 32PBe, kungofanana neNetApp masisitimu (kuti inyatsojeka, ivo vane 31.64PBe). Uye izvi zvisinei nekuti madhiraivha evhoriyamu imwechete anotsigirwa (kusvika ku15Tb). Huawei anotsanangura chokwadi ichi sezvinotevera: ivo havana kuwana mukana wekuunganidza yakakura kumira. Muchiono, ivo havana vhoriyamu muganho, asi ivo havasati vakwanisa kuyedza chokwadi ichi. Asi pano zvakakosha kucherechedza kuti kugona kwemadhiraivha nhasi kwakakwira zvakanyanya, uye mune yeNVMe masisitimu takatarisana nenyaya yekuti makumi maviri nemana madhiraivha anokwana kushandisa yepamusoro-yekupedzisira 24-controller system. Saizvozvowo, kuwedzera kwekuwedzera kwehuwandu hwema disks muhurongwa hakuzongopa kuwedzera kwekuita, asi kuchavawo nemigumisiro yakaipa paIOPS / Tb ratio. Ehe, zvakakosha kuona kuti mangani madhiraivha iyo 2-controller masisitimu 4 uye 8000 anogona kubata, nekuti ... Kugona uye kugona kweKunpeng 16000 hazvisati zvanyatsojeka.
- Kuvapo kwaLun semuridzi weNetApp masisitimu. Avo. Mutongi mumwe chete ndiye anogona kuita maoparesheni nemwedzi, nepo wechipiri achingopfuura IO pachayo. Huawei masisitimu, pane zvinopesana, haana chero varidzi uye mashandiro ane data blocks (compression, deduplication) inogona kuitwa chero ipi yevatongi, pamwe nekunyorerwa kune disks.
- Hapana chiteshi chinodonha kana mumwe wevatongi atadza. Kune vamwe, nguva ino inotaridzika zvakanyanya kunetsa. Chinonyanya kukosha ndechekuti kuchinja mukati mekuchengetedza system kunofanira kuitika nekukurumidza kupfuura padivi rekugamuchira. Uye kana mune imwecheteyo NetApp, mukuita takawana kutonhora kweanosvika 5 masekonzi pakuburitsa mutongi uye nekuchinja nzira, saka nekuchinja kuHuawei isu tichiri kufanira kudzidzira.
- Hapana chikonzero chekutangisa controller kana uchivandudza. Izvi zvakanyanya zvakatanga kundinetsa nekuburitswa kwakaringana kweshanduro nyowani uye firmware matavi eNetApps. Ehe, zvimwe zvigadziriso zveHuawei zvichiri kuda kutangazve, asi kwete zvese.
- 4 Huawei anodzora pamutengo wevaviri NetApp controllers. Sezvandambotaura pamusoro, nekuda kweHuawei's pricing policy, inogona kukwikwidza neMid-range nemhando dzayo dzepamusoro-soro.
- Kuvapo kwemamwe machipisi mumasherufu ekudzora uye makadhi echiteshi, ayo angangove akaitirwa kuvandudza mashandiro ehurongwa.
Cons uye zvinovanetsa pane zvese:
- Yakananga kubatana kwemasherufu kune vanodzora kana kudiwa kwenhamba huru yekumashure-yekupedzisira madoko kuti abatanidze masherufu kune controller.
- Arm architecture uye kuvapo kwenhamba huru yemachipi - ichashanda zvakadii, uye kuita kwacho kuchakwana here?
Kunetsekana kwakawanda uye kutya kunogona kubviswa nekuyedzwa kwako pachako kwemutsara mutsva. Ndinovimba kuti munguva pfupi mushure mekusunungurwa ivo vachaonekwa muMoscow uye pachava nevanokwana kuti vakurumidze kuwana imwe yebvunzo dzenyu. Kusvika ikozvino, tinogona kutaura kuti kazhinji nzira yekambani inotaridzika inonakidza, uye mutsara mutsva unotaridzika zvakanaka chaizvo kana uchienzaniswa nevakwikwidzi vayo. Kuitwa kwekupedzisira kunomutsa mibvunzo yakawanda, nekuti Tichaona zvinhu zvakawanda pakupera kwegore, uye pamwe chete muna 2020.
