Senior Enterprise System Engineer at Zenith-bank

I give the stability a ten out of ten. There is never a moment of system downtime since it is designed to be both rugged and agile, with a focus on resilience.

I have had customers who have been using it for three years with no issues. You don't need to do a reboot. I run Linux on Power Systems and it is more stable. You don't need to reboot over again.

I'd rate the stability ten out of ten. There aren't bugs or glitches. It doesn't crash or freeze. It is very reliable and offers very good performance.

Breakdowns are there in the solution, but since their service level is high, such issues get taken care of within 24 to 48 hours maximum.

It's very, very stable. I've never seen it go down for any reason. I would rate the stability a ten out of ten. 

IBM is much more stable than Oracle or HPE. We find it the most stable system in the market.

It's not the hardware itself that's unstable as much as it is the software. The hardware is stable enough. However, the software from time to time requires maintenance, and that requires us to reinstall some of the features. Sometimes we face problems with upgrading to newer versions or updates. Occasionally, we have to revert back to an older version. That said, in terms of the hardware itself, it's stable enough. We haven't had any failures so far in the hardware, with the exception of hard drives.

Lots of issues, but with hardware an issue we faced with our POWER7s has been the voltage regulators. IBM has been pretty good about that. They've been keeping voltage regulators onsite, so that if we do have an issue they're able to replace them in an expedient amount of time.

Stability is great. The old saying was, you talked about the "five 9s" of reliability. We're at something like seven 9s. We've never really had a major outage. 

We've had outages, but it was the network that went down, or a SAN outage, or somebody, a person, pushed the wrong button. But the infrastructure itself, the IBM Power hardware has never failed us.

The upgrade from version to version is not complex. I think it's fairly straightforward and IBM provides a lot of documentation, check-listing, features, so all you've have to do is be methodical, go through the checklists step by step and it's fine.

Very stable, absolutely. POWER9 is expected in the market and that's going to be, I would say, revolutionary. It is going to turn around the market in terms of the market share, in favor of Power Systems. I would say that if the price point is right, and the execution is good, this can really be a very successful platform for mission critical applications in future.

We have had issues, but they haven't been because of Power, they've been because of partner errors on our system.

JL
Senior Pre-Sales Manager at PT GLOBAL INFOTECH SOLUTION

It's very stable. They have a different Hypervisor compared to an Intel-based Hypervisor, like VMware or Red Hat. The Red Hat Enterprise Virtualization is like an embedded Hypervisor, so you don't have to rest up the server. If you ever install the packets or any update, it does not require you to rest up the server. It's more stable, and you don't need more downtime.

Aix lead at a manufacturing company with 10,001+ employees

AIX is very stable. Our whole Power system has been very stable. We very rarely have outages. Most of the outages have not been attributed to the hardware, it's more attributed to network or SAN. 

Now we have had some hardware outages, but those are based on doing maintenance such as firmware upgrades, and the like. Those have caused issues, but you know when those are happening because you've already had them scheduled. So you know to be prepared for it, what work will be done.

IBM is quite stable. That's one of their most popular aspects. We just upgraded our power systems recently, so we're going to be working with them through the next five years at least.

The solution is being used quite heavily.

Server Support Specialist at a tech vendor with 10,001+ employees

The stability of IBM Power Systems along with the AIX operating system is unmatched. Once you are up and running, you will rarely face any outage. You cannot compare it to any other platform.

Once you are up and running and do not make any changes to your configuration, you will not face many issues. Errors and VFDs outages have been rare as well. If you do not make changes and keep your environment stable, you will not have any outages.

On a scale of one to 10 - I've been doing this for 30 year's - I'd give it a ten, being the best. They're always there. They're always available. When the other platforms are going down, and they're working on them all the time, mine's always up. When the other platforms are having security issues, no one's getting into mine.

I think they still claim "five 9s" availability. I would have to agree. In my experience, starting out as a CE back in the day, they were always very reliable, very easy to fix when they did break. With some of the other RAS things that they've put into these boxes, they're the best.

Upgrading from POWER7 to POWER8 was not a big deal. It was pretty straightforward, I would say. Going from version 5.4 to a 6, that was more of a challenge, but now it is pretty stable. We have some partitions running 7.3, some running 7.2 version. All over the map.

EVP Technical Solutions at Helpsystems

The stability and scalability is why you invest in IBM i. You don't have issues. Like any organization, we have some other applications that run on non-IBM i stuff and to say that it's as reliable - it's not. With IMB i you know it's there, you don't even think about, "Is the server available? Is my application available?" It's always available. 

I travel around visiting hundreds of customers every year and it's the same story. We don't have a problem. I was at a customer a couple weeks ago and they talked about that IBM i had been running for over a decade without any outage, until somebody was in the back room moving some wires around, a new electrician in the company, and they accidentally turned off the wrong switch. And then they had some outage. 

But it's human error that causes the problem. It's not the system itself, it's not the operating system or the hardware that's a problem.
