Semuyenzaniso, kana sisitimu yave kuita nhanho padanho rekudonhedza uye kudzvanya, saka mamwe macores anogona kunge ari mukati mekuita sevhisi I / O. Kana zvakasiyana. Zvese izvi zvinoitwa otomatiki uye pachena kune mushandisi.
Dhata pane yazvino mutoro weimwe neimwe yeDorado V6 cores haina kuratidzwa mune graphical interface, asi kuburikidza nemutsara wekuraira unogona kuwana iyo controller OS uye kushandisa yakajairwa Linux command. pamusoro.
NVMe uye RoCE rutsigiro
Sezvambotaurwa, Dorado V6 parizvino inotsigira zvizere NVMe pamusoro peFiber Channel kunze kwebhokisi uye haidi chero marezinesi. Pakati pegore, tsigiro yeNVMe pamusoro peEthernet modhi ichaonekwa. Kuti ishandiswe zvizere, iwe uchada tsigiro yeEthernet ine yakananga ndangariro kuwana (DMA) vhezheni v2.0 zvese kubva kune yekuchengetera system pachayo uye kubva kune switch uye network adapter. Semuenzaniso, seMellanox ConnectX-4 kana ConnectX-5. Iwe unogona zvakare kushandisa network makadhi akagadzirwa pahwaro hwemachipi edu. Zvakare, RoCE rutsigiro runofanirwa kuitwa padanho rekushandisa system.
Pakazara, isu tinoona iyo Dorado V6 seNVMe-centric system. Zvisinei nerutsigiro rwuripo rweFiber Channel uye iSCSI, mune ramangwana rakarongwa kuchinjika kune yakakwira-speed Ethernet neRDMA.
A pinch of marketing
Nekuda kwekuti iyo Dorado V6 sisitimu inoshivirira zvakanyanya, zviyero zvakanaka, inotsigira akasiyana matekinoroji ekufambisa, nezvimwewo, hupfumi hwekutora kwayo hunova pachena nekutanga kwekushandisa zvakanyanya kwekuchengetedza masisitimu. Ticharamba tichiedza kuita kuti hutori hwehurongwa huve hunobatsira sezvinobvira, kunyange kana padanho rekutanga zvisingaoneki.
Kunyanya, isu takagadzira iyo FLASH EVER chirongwa chine chekuita nekuwedzera kutenderera kwehupenyu hwekuchengetedza masisitimu uye yakagadzirirwa kuburitsa mutengi zvakanyanya sezvinobvira panguva yekusimudzira.
Iyi purogiramu inosanganisira akati wandei matanho:
- kugona kutsiva zvishoma nezvishoma vatongi uye dhisiki masherufu neshanduro nyowani pasina kutsiva iyo yese midziyo (yeDorado V6 hi-end system);
- mukana wekuchengetedzwa kwemubatanidzwa (kubatanidza shanduro dzakasiyana dzeDorado sechikamu cheimwe hybrid yekuchengetedza cluster);
- smart virtualization (kukwanisa kushandisa wechitatu bato Hardware sechikamu cheDorado mhinduro).
Kunosara kucherekedzwa kuti mamiriro ezvinhu akaoma munyika akanga ane tapuro duku pakariro dzezvokutengeserana dzegadziriro itsva. Kunyangwe hazvo kuburitswa kwepamutemo kweDorado V6 kwakaitika muna Ndira chete, tinoona kudiwa kukuru kwairi muChina, pamwe nekufarira kukuru mairi kubva kuRussia nevekunze vanobatana kubva kumari nehurumende zvikamu.
Pakati pezvimwe zvinhu, zvine chekuita nedenda, zvisinei kuti vagara kwenguva yakareba sei, nyaya yekupa vashandi vari kure nemadhesikirwo echokwadi yakanyanya kuoma. Mukuita uku, Dorado V6 inogonawo kubvisa mibvunzo yakawanda. Kuti izvi zviitike, tiri kuita zvese zvinodiwa, kusanganisira kubvumirana kubatanidzwa kweiyo itsva system muVMware inoenderana rondedzero.
