Allan Adamson ndiro zita raOracle mainjiniya akapa basa iri. Anoshanda paLinux kernel kuvandudza yekambani iyi distro, uye ikozvino awana sumo yekubatanidza NVMe flash kuchengetedza kuburikidza neTCP.
Oracle Linux UEK5 Iyo ndiyo vhezheni yakaunzwa neNVMe paMachira, nokudaro ichibvumira mirairo yekuchengetedza yeNMeMe kutamisirwa pamambure akaita seInfiniband kana Ethernet ichishandisa RDMA, ese ari maviri anoshandiswa zvakanyanya muHPC nenzvimbo dzematare. Mune iyo UEK5U1 vhezheni, iyi rutsigiro yakawedzerwa kuti itsigirewo fiber optic chiteshi.
Iye zvino muUEK6 iyi nyowani NVMe pamusoro peTCP, iyo zvakare inowedzera pamusoro apa kutsigira yakajairwa Ethernet pasina kutenga RDMA-inoenderana spatial network Hardware.
Zvino kana iwe uchinetseka chii icho icho nezveNVMe pamusoro peTCPIwe unofanirwa kuziva kuti NVMe's yakawanda-queuing modhi inoshandisa inosvika ku64.000 I / O kutumira uye kupedzisa mitsara, pamwe neumwe manejimendi anotumira mutsara uye mumwe mutsetse wekupedzisa mukati mega yega NVMe controller. Nezve PCIe-yakasungirirwa NVMe controller, iyi mitsara inoitwa neyekugamuchira memory uye inogoverwa neese ari maviri anogamuchira CPU uye anodzora NVMe.
Iyo I / O inotumirwa kune NVMe chishandiso kana mutyairi wedhizaina anonyora rairo kumutsetse wekutumira obva anyora danda kuti azivise mudziyo wechiitiko ichi. Kana iwo murairo wapera, chishandiso chinonyorera kune I / O mutsara wekupedzisa uye inogadzira kukanganiswa kuzivisa mutyairi wedhizaiti kuti apedza.

NaNVMe pamusoro peMachira ichi chirongwa chakakosha chekutumira uye kupedzisa mitsetse muyeuchidzo yekugamuchira inowedzerwa kuitira kuti vagone kudzokororwa mu remote controller, Saka kuti inomiririra-yakavakirwa mutsetse mepu yakarongedzwa kune inodzora-yakavakirwa mutsetse vaviri. Chinhu icho chePC hachina musoro asi icho che HPC zvishandiso nemaseva zvinogona kunakidza kwazvo kure kure kutaurirana pakati penzvimbo ...
Kana kuwanikwa uku kuchidudzira mune yakawanda data kubudikidza pasekondi, ngazvive saizvozvo.
