== Supported Operating Systems ==

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 ^ Inventory Command^
| VAX/VMS | VAX Systems such as the 11/780, 11/750, MicroVAX II (or even I), or MicroVAX 3100 | 1.0 - 7.3 | Yes! We still support VMS running on the VAX | show device /full |
| OpenVMS   | Alpha EV4, EV5, EV6, EV7 systems as well as Itanium (Integrity) and X.86 | 6.3 - 8.4-2L3 (Alpha) 8.0 - 8.4-2L3 (Integrity), 9.1 - 9.2-2 (X.86) | This is the modern OpenVMS versions on Alpha, Itegrity, and X.86 | show device /full |
| 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, including non-x86 platforms| dmidecode ; lspci |
| 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. We also support TruCluster and AdvFS layered products| hwmgr show component |
| 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. We can only give reasonable effort support for Sun Cluster (no layered product support for it)|prtdiag -v|
| 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!)|lsconf|
| 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). We'll also support MirrorDisk|echo "selclass qualifier memory;infolog" %%|%% /usr/sbin/cstm |
| IRIX | MIPS R3000 and anything after | We'll support IRIX versions 5.0 - 6.5 on any system with a MIPS R3k or better|We support CXFS and some layered products as well|hinv -mv ; gfxinfo|

=== Additional Layered Products We Support ===

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. 

  * DECnet for OpenVMS and Tru64
  * MultiNet for OpenVMS
  * AdvFS for Tru64
  * Veritas Volume Manager (VxVM) for all Unix platforms we support
  * Sun DCE
  * IBM PowerVM also sometimes called VIOS
  * HACMP also called PowerHA for AIX
  * ServiceGuard for Linux and HPUX
  * CXFS for IRIX

=== Things We Don't Support === 

Here are a list of things we get asked about fairly often that we, unfortunately, do not offer support for at this time. 

  * DEC Ultrix
  * Tandem / Nonstop
  * VxWorks
  * MS-DOS, CPM, AmigaOS, MacOS, OS/2 (ie.. nothing on micros)
  * NeXTStep, Mach, or OpenStep
  * SunOS 4.1.2 or earlier
  * Dynix
  * UNICOS (though we do have some experience with this platform for consulting purposes)
  * A/UX (we **do** support AIX, but A/UX is a fun old early-90's Apple Unix variant that never took off)
  * AT&T Unix (mainly because nobody has ever asked)
  * DG/UX
  * Rdb (Rdb/Oracle and VAX/Rdb) for OpenVMS and VAX/VMS
