IBM Power Systems Review

We used the CUoD feature to enable four more cores on our server

What is most valuable?

I just like the levels of redundancy that are there. Your power's redundant, your pathing's redundant. You can split up your buses, split up your expansion units. It's hard to take those boxes down, really. So, if they are up they'll run for years.

One other thing I really like is how they are going to integrate the HMCs into the frames now, so you don't have a standalone appliance, it's just built into the frame. I haven't worked with anything like that yet but hopefully soon.

How has it helped my organization?

One of the big things I've seen is that you can dynamically move devices or processor memory, capacity on demand, things like that. We actually just used the CUoD feature this past year. We enabled four more cores on our server. It kinda got us out of a gray spot.

For me, as an AS/400 I series guy, I think there's a lot of benefits to that OS. I think a lot of users really like it, despite the green screens. But after you get working with it, you're very familiar with it. So, to me, the hardware's there and I think the AS/400 or iSeries OS is very good as well.

What needs improvement?

I would like for there to be more clarity around the licensing. You'll get your PVUs and CPWs and some apps are licensed on one, some are on another.

For how long have I used the solution?

That box has probably been running for us for over 10 years. I've been working with Power directly for over five years.

I primarily work with Power 570, and so we're running some of our AS/400 on it with IBM i. We are also running POWER8 in the right spots in our environment. I'm kind of known as the legacy track but I'm glad to have the 570 anyway.

What do I think about the stability of the solution?

The stability is beyond belief. You can't beat it. 

What do I think about the scalability of the solution?

We experience issues every once in a while. I think it's more due to our applications and how we're licensed that sometimes we have to get a little crafty there.

How is customer service and technical support?

They're very strong. And especially the FSRs that come out. Those guys have been working with Power boxes for decades.

Which other solutions did I evaluate?

No, we are pretty set with IBM Power. We're running AIX and SAP all on Power boxes.

What other advice do I have?

I definitely see IBM as a market leader in the server industry in regards to their hardware. There is a lot of talk about them going more open-source and I think they are there, running Linux on Power and being more actively involved with that user group. But that's maybe a catch-22 as well, but I think they are leveraging that and that is what is going to take them forward.
