VMS Software, iyo makore mashanu apfuura yakatenga kodzero kubva kuHewlett-Packard kuti ienderere mberi nekugadzira iyo OpenVMS (Virtual Memory System) inoshanda sisitimu, yakaburitsa kuburitswa kweOpenVMS 9.1, inozivikanwa nekuita kwayo kwerutsigiro rweiyo x86-64 architecture. Iyo OpenVMS inoshanda sisitimu yakagadziridzwa kubva 1977, yakashandiswa mukutadza-kushivirira masisitimu ayo anoda kuwedzera kuvimbika, uye yaimbowanikwa chete yeVAX, Alpha uye Intel Itanium architecture. Zvakakosha kuti kuyedza kuendesa OpenVMS kune x86 masisitimu pakupera kwema1980 hakuna kubudirira nekuda kwekumira kwemari, mushure mezvo munyori wechiteshi akatamira kuMicrosoft ndokugadzira Windows NT.
Iyo yakatsanangurwa OpenVMS chiteshi cheiyo x86-64 architecture, mukuwedzera kune yekumisikidza pane chaiyo hardware, inotsigira kushandiswa muKVM, VMware uye VirtualBox chaiwo michina. Chiteshi chinovakwa zvichibva pane imwecheteyo OpenVMS sosi makodhi ayo anoshandiswa mushanduro dzeAlfa neItanium zvivakwa, uchishandisa zvinemimisheni kuunganidzwa, kutsiva maficha akasungirirwa kune maficha ehudhivha.
Iyo OpenVMS kodhi yakagadziridzwa kuti ivakwe ichishandisa LLVM pachinzvimbo chemuridzi GEM compiler yakashandiswa kuvaka Alpha neItanium ports (muturikiri akanyorwa kuti aratidze GEM IR kuLLVM IR, uye Clang yakagadziridzwa kuvaka C++ kodhi ye. OpenVMS). UEFI uye ACPI inoshandiswa pakuona hardware nekutanga, uye kubhowa kunoitwa uchishandisa RAM dhisiki pachinzvimbo chehardware-chaiyo VMS boot mechanism. Kutevedzera yakarasika VAX, Alpha uye Itanium ropafadzo nhanho dzisiripo pa x86-64 masisitimu, iyo OpenVMS kernel inoshandisa iyo SWIS (Software Interrupt Services) module.
