Thoughts on HP-UX, AIX, and Integrity

Those who know me personally and have been following this blog know that I ditched my HP-UX admin career to become a systems architect in another division at my company. The reasons for this were mostly personal, although maybe 10% of my choice to move on was due to other reasons. Bottom line is that even though I miss the technical side, I'm glad I've made the switch to the "clouds" and became an architect.

I'm now mostly attached to stuff made by Cooper Power Systems and OSISoft, which is fine. Expect the content of this blog to switch to these two vendors over time. HP still has a place too, as I've spent so much time using their products. But here we're not a HP shop; we have some HP products of course, but also IBM, EMC, and other vendors on the floor.

Some HP reps came in this week to show us what was new this year. While I used to be very fond of HP since relying on a limited number of manufacturers was part of my one-sysadmin-for-all strategy, I must now step back and try to be as objective as possible.

That being said, there was the usual presentation about let-HP-shove-its-converged-infrastructure-down your-throat, then a half-hour presentation on Integrity systems (among others) during which I kept my mouth shut. I couldn't help myself thinking what's the future of this great platform. All talk about running Linux and Windows on the platform is now gone, which is a good thing, as we all know it can no longer be an option. Only HP-UX and OpenVMS are left. The BCS rep, knowing my division runs RHEL and AIX, told us to "please challenge us", meaning that we should evalutate HP-UX as a contender as much as possible.

I've worked with HP-UX for 10 years and love it. But, in my opinion, AIX is roughly equivalent. Although I haven't been administering AIX systems for 10+ years, I know enough that it is a mission-critical OS backed by a manufacturer who won't let my company down, same as HP-UX. If we were running Solaris, things would be very different. But for the moment, as an architect, I consider both HP-UX and AIX as equals: these are the last true "Enterprise" UNIX options available.

So, what's left for the Integrity platform? Not much. As AIX is the same as HP-UX at a glance, I can only think that Integrity is the same as POWER systems, give or take. So it's not a bad platform per se, but a niche one for sure.

It's too bad HP lost the big bet they've made on the Itanium. I still remember all the talk about Merced when I started my sysadmin career in the late 90s. Things didn't turn out as expected for sure, but even if HP had stayed on the PA-RISC bandwagon, they would be at the same spot they are right now. That doesn't mean HP-UX has no future - the OS still has a big place in my heart. I can only hope HP will eventually port the HP-UX kernel to x86, or make an HP-UX ecosystem and support infrastructure revolving around a Linux kernel. This is probably the best thing to do to this operating system to ensure its long term viability.
