There are a lot of legacy operating systems and hardware. We support a lot of things, but not everything. Sometimes it's confusing to tell. PARSEC doesn't support hardware directly. We work with other hardware partners who have things like parts depots and field engineers to support the operating system running on that older hardware. Below is a table breaking down what operating systems we do support and the usual sort of hardware it runs on.
|Operating System Name||Common Hardware or CPU||Version Numbers||Notes|
|VAX/VMS||VAX Systems such as the 11/780, 11/750, MicroVAX II (or even I), or MicroVAX 3100||1.0 - 6.4||Yes! We still support VMS running on the VAX|
|OpenVMS||Alpha EV4, EV5, EV6, EV7 systems as well as Itanium (Integrity)||6.3 - 8.4||This is the modern OpenVMS on both the Alpha and Itanium|
|Linux||x86, SPARC, Alpha, or Integrity||all versions but only RHEL, Debian, or SuSE distributions others by approval only||We basically support anything that runs Linux|
|Tru64||Alpha EV4 to EV7||1.x - 5.1B patch 10 (last version)||Remember it was also called OSF/1 and Digital Unix before it was renamed in the 5.x days|
|Solaris||SPARC and X86||2.4 - 11.3||We also support the ancient SunOS and transitional or special versions such as Trusted Solaris and Solaris on Fujitsu SPARC servers|
|AIX||RS/6000, POWER4 - POWER9||3.x - 7.x||We don't support the 1980's versions and we don't support the super-obscure PS/2 version (but we'd love to see someone running it!)|
|HPUX||HPPA (PA-RISC or Precision Architecture) and the Itanium / Integrity versions||10.x - 11iv3||We don't support the old Motorola 68k platforms (but we love the 68k, nonetheless)|
|IRIX||MIPS R3000 and anything after||We'll support IRIX versions 5.0 - 6.5 on any system with a MIPS R3k or better|
Sometimes vendors sell additional functionality for their operating systems as a separate item. We use the old phrase “layered products” to describe this situation. Here is a list of layered products we support. In some cases, we may also agree to support one not on this list.
Here are a list of things we get asked about fairly often that we, unfortunately, do not offer support for at this time.
