I can now buy one 4U box with 16 cores and put a terabyte of memory in it

What is most valuable?

Flexibility and reliability are the two features that are probably the most important to us.

How has it helped my organization?

We get better performance out of our applications, out of our databases running on Power, than we would on anything else that we have looked at.

What needs improvement?

I think they could use a little more work in the upgrading of the OS, how that could happen as non-interrupting, but I think they are working on that.

What do I think about the scalability of the solution?

Scalability is awesome because we can move from POWER8 to POWER9 when the new servers come out. It allows us to scale out, add new servers underneath it, buy new equipment and add it into the datacenter.

How was the initial setup?

It was pretty straightforward. The partition mobility helps a lot.

What was our ROI?

We do see a return on that investment, especially on the software licensing, when we are licensing DB2 or we are licensing WebSphere. We have seen that we have had to license fewer cores on the POWER8 than we had on the POWER7.

What's my experience with pricing, setup cost, and licensing?

We've been using more of the mid-range systems than some of the bigger models, and we like that price point. We like where we are at there. It allows us to scale out the datacenter faster. It also allows us to react to a company or an application that's growing faster than someone else.

Which other solutions did I evaluate?

No. We were an HPE shop and we converted over to Power at POWER5. We thought the Power roadmap was just better, better suited for us.

What other advice do I have?

Using the Power system gives us a leg up. It helps us keep up with the competition.

What we like the best about the POWER8 is that it scaled down in size and power usage. When we were buying POWER5, we had to buy a 16U rack to get 16 cores and maybe a half terabyte of memory. Now I can buy one 4U box with 16 cores and put a terabyte of memory in it, and I'm in business.

We have now started thinking about moving to Linux on Power. We are just starting to scratch that surface.

The ongoing work that is being done behind the scenes, that keep improving the product, logical partition mobility, PowerVM, PowerAIX. I think that all of those help contribute to the way Power is running.

I do consider IBM to be a market leader and in order to remain a market leader they just need to keep improving. Keep improving the product, keep pushing the product. I think it looks great.

It facilitates extra redundancy and we run our critical applications on it

What is most valuable?

Primarily the reliability. I can set up a system and it runs until we decide to get rid of it.

How has it helped my organization?

The reliability is one. We have a lot of extra redundancy built into Power and we run our critical applications on there so it protects our brand and our business.

For how long have I used the solution?

Since POWER4.

What do I think about the stability of the solution?

We are very happy with the performance.

What do I think about the scalability of the solution?

No, we have not.

How is customer service and technical support?

It's very good. They are knowledgeable and there is always a point of contact.

What was our ROI?

POWER8 definitely handles the workload better than POWER7 did, as far as the threading between having a lot of partitions running in a system. There is less impact when the system doesn't bog down, when a lot of applications are running.

What's my experience with pricing, setup cost, and licensing?

Licensing is not an issue but it is something that we are being asked for from our leadership. Because usage fluctuates all the time, they want to know that they are only paying for what they are using. And we're all competing against the cloud vendors now.

Which other solutions did I evaluate?

No. We have been running on Power ever since we went to SAP.

What other advice do I have?

I am using POWER8 for AIX and Linux.

I wouldn't say that Power uniquely positions our company in the industry. We run all of our internal applications on it and we keep our business running with it.

As far as IBM being a market leader, I would think that they are certainly one of the players, I don't know if they are the leader or not. In order to be a market leader I think IBM would have to get into more shops and get the word out there. It's kind of like the Windows mentality, a lot people go with what they know or what they see advertised.

It's even more flexible with the ability to create an environment in a few minutes

What is most valuable?

It's flexible and it's reliable.

What needs improvement?

They can make it easier to do the patching and iFixes, which is especially important now, with all of the security issues. That would provide a lot of relief.

For how long have I used the solution?

I recently joined the team, but I think they started moving to Power about a year ago, at least.

What do I think about the stability of the solution?

We are very happy with Power's performance.

What do I think about the scalability of the solution?

No, absolutely not. Especially now, with the VC, it's even more flexible with the chance to create an environment in a few minutes, especially for testing.

How are customer service and technical support?

Pretty good. We had a few engagements with the labs.

Which solution did I use previously and why did I switch?

We have always used Power.

How was the initial setup?

Thanks to the labs, the migration from POWER7 to POWER8 was easy.

What was our ROI?

We were able to reduce to a single frame.

What's my experience with pricing, setup cost, and licensing?

I don't really wish the licensing was more cloud-based. It is not really an issue. It could be.

What other advice do I have?

I'm using POWER8 right now and migrating some of the POWER7 systems. I am using it with AIX and IBM i. Mostly the core is IBM i. We have an e-commerce website and it is running on AIX.

I don't know how IBM could maintain their status as a market leader in the servers sector, but I would like to see more young people at this kind of event, the IBM Power Conference. That would probably help.

The improved SMT has helped open up boundaries for applications that can use it
Pros and Cons
  • "The SMT that they've improved has really helped open up boundaries for other applications that can use it."

    What is most valuable?

    I can get more work done with less hardware. The SMT that they've improved has really helped open up boundaries for other applications that can use it. The ones that can't, they're still single-threaded, still waiting on the CPU cycle.

    How has it helped my organization?

    When using it with the virtualization, we've finally gotten to the point of being able to do what VMware VirtualCenter does, but we do it more robustly, a lot faster and probably easier.

    What needs improvement?

    I don't know yet. We have got scalability, resiliency. We can move it from one system to another.

    Licensing is always going to be a problem, because it used to be based on, "This is a CPU, this is the memory, this is your footprint." Now, with virtualization, that one CPU can be carved up 100 different ways, so why should I be charged for that use rather than a single CPU, a single socket? But businesses have to make money.

    For how long have I used the solution?

    I have been using Power for maybe 15 years; POWER8 since it came out, a couple of years ago.

    What do I think about the scalability of the solution?

    No we haven't. We pushed it as far as it could go. There have been times I've put maybe 60, 70 machines on a single POWER8 box which, with the poll sharing and the resource sharing, you can do but you have to actually plan it out accordingly.

    How are customer service and technical support?

    It's like any other support organization. You can get some top-notch people, and then you can get some who you have to escalate. If you don't escalate, you're not going to get the support that you need. But overall, response has been pretty good.

    Which solution did I use previously and why did I switch?

    Intel was the previous solution. The performance wasn't there. Linux on Power, I believe they're one of the first implementers on it. I think that was under POWER4, when no one knew anything about it. But it worked, worked beautifully. The hard part was I couldn't move that workload from one machine to another because it wasn't available. But it's a lot more robust now.

    With Intel, it's a matter of complicated instruction set versus reduced. Using Power we get more scalability, more power, less need for resources, hardware, etc.

    How was the initial setup?

    It's not as easy as clicking boxes and setting up Windows. You have to actually do a lot of pre-planning, a lot of figuring out whats your workload is, what your footprint is, your memory size.

    You can get a person who has never seen it before to be able to do it themselves. With the cloud offering, it's point and click, literally. The resources are there. They tell it what they want, where they want it, how much they want, and click, they have a machine.

    What other advice do I have?

    I mostly use AIX along with some Linux, POWER8 and POWER7.

    It's hard to say how the Power system uniquely positions our company in the industry because we try to do everything. But we usually try to push the Power first. Our company mainly started with strictly iSeries, so you can't run that on Intel. So when Power came out and showed that it was a much better workhorse for the iSeries, it was good. Life was great. Actually, I believe iSeries was virtualizing long before Intel even thought about it. But some of the iSeries guys will tell you, "We don't know what it is."

    Regarding the OpenPOWER Foundation, it has offered us a faster way of deploying multiple systems in a shorter amount of time. In the good old days, it would take you a few days just to create one system. Nowadays, you can possibly deploy 10 in the time it would take one.

    I consider IBM a market leader in the server sector, compared to Dell and Lenova, because, they have more robust, faster hardware that can be deployed and implemented a lot faster than Intel, even with VMware.

    VMware has point and click, but there's a real steep learning curve in your networking, your shared resources, your performance tuning and your troubleshooting.

    In order to remain a market leader I would say that IBM needs to stay ahead of the curve. They need to listen to what their customers are saying as far as, "I want this feature or that feature." If it can be done, do it. If it can't, let the customer know. "Hey, we'll look at it and get it in the future."

    I would definitely recommend Linux on Power rather than Intel.

    Convergence means all of our storage, processing, database in one platform

    What is most valuable?

    I would say the converged feature. You can have all of your storage, your processing, your database, everything in the one platform, and all under IBM. That's the best part of it. 

    How has it helped my organization?

    It has helped them improve in a lot of ways. It has improved their efficiency as well as their scalability, from a growth perspective. They want to add more servers, more processing power, things like that. They can be much more easily done now.

    What needs improvement?

    I would say that in general we would prefer it if the software was more transparent, in terms of how you are using it. 

    Right now it depends on the level of the system and how much more you might have to pay for the same software. And being a cloud provider, we get into a lot of situations where our customers might need just a fraction of a processor, but they still have to pay for a bigger portion of the software costs.

    For how long have I used the solution?

    We have been providing this for the last 15 years.

    What do I think about the stability of the solution?

    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.

    What do I think about the scalability of the solution?

    Scalability is great. With the VIOS, the Power and the Power platform, we can virtualize. We can create many more LPARs.

    It is definitely a more flexible solution, compared to earlier versions. You want to be able to cater to multiple customers on one particular system. We have dozens of systems running in our environment right now.

    Back in the day, it used to be more hardware-centric. Now, with the software version, it is much easier for us to create multiple partitions. We may run a POWER8 system with 20 cores, and we could have, maybe, 30 customers on that one box by slicing and dicing it. So it is pretty good, from that perspective.

    Which other solutions did I evaluate?

    We are the service provider and so we have the IBM i at every level in the cloud. This is pretty much due to the demand from the customers. It's not us, it's really our customers asking for it.

    We also work with other solutions. We do everything; we do Windows, Linux, AIX, as well as IBM i. All different platforms. 

    Compared to Intel, Power is a much more stable solution. Security is also much better. Compared to the other platforms, Power definitely has more capabilities.

    What other advice do I have?

    There are not many companies in the US who can provide the IBM i platform in the cloud so we are uniquely positioned in being able to cater to that particular requirement of our customers.

    I would consider IBM to be a market leader from the Power side, but not in other areas. I think they were getting there but they made a big mistake by selling the PureFlex to Lenovo.

    Helps us manage Oracle and WebSphere licensing, AIX is reliable and the performance is good

    What is most valuable?

    • AIX
    • Reliability
    • Performance, of course
    • The ease of use
    • It's really enterprise ready (whereas Linux is less enterprise ready)
    • I would say that the best feature right now of Power is the license management. We use it for Oracle and WebSphere and it's good for that. As I said the reliability of the AIX OS and hardware is very good.

    What needs improvement?

    The only thing that I've seen over the last years - and I think it's getting better - would be to have stable service packs. Often I upgrade to a new version, a new service pack, and we need to put iFix over the service pack. I would like to have the service pack be really stable, or IBM saying, "This service pack is stable, but you should add this and this iFix as of right now." That would be better.

    It would be an improvement if the cost went down, as well.

    What do I think about the stability of the solution?

    Mature and stable.

    What do I think about the scalability of the solution?

    Great, but at our company we don't need the scalability that AIX and Power offer, so we are kind of in the medium range of requirement.

    How is customer service and technical support?

    Good, and a lot better than other companies.

    How was the initial setup?

    I would say pretty straightforward.

    What was our ROI?

    Mainly performance and flexibility is getting better and better. So I would say yes, slowly but steadily, we are seeing a return on investment of the expense in upgrading from the previous versions to the version we're using now.

    Which other solutions did I evaluate?

    We use a competitor, Intel-based Linux. We went with Power because of reliability, performance; it's a good product overall.

    What other advice do I have?

    When I rated it 10 out of 10, I ignored the pricing. It's costly, so it's part of the business decision. Hardware prices put the brakes on some solutions.

    I don't consider IBM to be a market leader in servers. They are in a very good position, but AIX is not sold to customers, it's not viewed as a prime solution.

    I think they need to push more AIX, openly, there's not enough noise about it. It's quiet, it works, so we don't talk about it. It's a local initiative it's not a global initiative.

    It has improved the stability of our Oracle database

    What is most valuable?

    • The Live Partition Mobility (LPM) feature.
    • The virtualization feature.

    Depending on the simplified remote restart for the DR, that's what we're looking forward to.

    How has it helped my organization?

    It has improved the stability of the Oracle database. We have a big database running in a Power environment and it is more stable than compared to what we are adding.

    What needs improvement?

    I would say the cost. They need to work on the cost because I think it's quite expensive and that's a changing trend in the industry, to be more focused on the product.

    For how long have I used the solution?

    I started using Power when I started at T-Mobile three years ago. They had POWER5, and we migrated them to POWER6. So it has been about three years, maybe a little longer.

    What do I think about the scalability of the solution?

    For the scalability, we do have the capacity planning and we do plan accordingly and I think we would go for POWER9 if we had to, depending on the usage. I think there is still scalability room for us.

    Which solution did I use previously and why did I switch?

    I think T-Mobile has a big shop of Intel for Linux servers and they have Power for AIX servers.

    How was the initial setup?

    I wasn't involved in the initial setup because we have an SME who does that and I'm just an engineer at the back end. I do the operations support, so that's where I come into the picture.

    What was our ROI?

    We do see ROI from the move from POWER7 to POWER8. We do capacity management and we are able to move quite a lot of workload.

    What's my experience with pricing, setup cost, and licensing?

    Would I prefer a license based on a cloud system?

    We have Pivotal Cloud Foundry (PCF) and that's more for the application side. I haven't dug into this more to check how the database would do on the cloud so I'm not sure about that.

    What other advice do I have?

    We are using AIX with POWER8 but we do have a mix of POWER7 servers as well. 

    We do capacity planning, and we try to maintain the Power capacity monitoring and to maintain that we've got enough capacity for a year worth of workload. We plan ahead as well for the coming workload. What we've got is enough for one more year.

    Virtualization is the key, as we can more easily spin up a new partition, virtual instance
    Pros and Cons
    • "From a software developer standpoint, virtualization is really the key, as we can more easily spin up a new partition, virtual instance of IBM i."
    • "Better manage heterogeneous footprints of all the different operating systems that are out there across one common interface."

    How has it helped my organization?

    I think the main thing that POWER8 is doing for the industry in general is it's leap frogging all the other technologies that exist out in the market from a performance capacity and total cost of ownership point of view. You can scale these servers up or scale out and replace a lot of footprint for other organizations. 

    An IBM i customer is more of a traditional business, they've been around for a while, they've been running on IBM i for, maybe, a couple decades and for them it's all about being able to continue to move forward, maybe even scale down the size of the server, the footprint of the server, the energy consumption and all those things that come along with it.

    What is most valuable?

    Help Systems is a provider of IBM i and AIX systems management software. We use the server in our infrastructure to develop technology to solve customers' problems in automation. We're using POWER7 and POWER8 servers, highly partitioned, virtualized; using SAN storage to help us build up our development environments.

    Our solutions include the top issue of the day which is security. Everybody's concerned about security, so we do that. We do automation software, which we've been doing for years, and then monitoring software also.

    From a software developer standpoint, virtualization is really the key, as we can more easily spin up a new partition, virtual instance of IBM i. We can have it preloaded with our different softwares that we need to test out. To me it's a virtualization. We use that through having a SAN and POWER8 technology.

    What needs improvement?

    With POWER it has everything that we need from a scale up and scale out capacity, capability to stick lots of work and footprint on it. For IBM, the challenge that everybody has in the industry, and in the processor world, is that we've kind of hit the "knee" of the curve with Moore's law. Processors aren't getting faster. The neat thing about IBM is the innovation that they're doing to offload work from the processor and do more simultaneous things. 

    I'm really excited about the artificial intelligence even if you don't always think of systems management companies like us being excited about that technology. But we have a lot of information too, and helping our customers more easily mine that - I see some great opportunities. 

    And to better manage heterogeneous footprints of all the different operating systems that are out there across one common interface.

    When we talk about cloud licensing, or maybe tenant-based licensing, definitely there's a shift in the marketplace in that more of our customers are looking at things like infrastructure as a service, where they're going to be having their IBM i footprint hosted by somebody else, maybe on somebody else's partitioning. Sister partitioned systems. So then licensing does become an issue in how do we take that on-prem customer perpetual license and convert it into something that they can consume as they go, because people are used to that with Amazon and other technologies.

    What do I think about the stability of the solution?

    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. 

    What was our ROI?

    Going from POWER7 to POWER8, the big thing to me is it's not even necessarily the performance, it's the capability of virtualizing, more easily done through some of the different technologies that we have so it can spin up new environments more easily.

    What other advice do I have?

    Today's world is more about the applications that we have. So, the challenge for the IBM i customer is staying up with time. We have to modernize. We've been talking about it for years - modernizing the applications - so that when my daughter or my son comes and works for you, they're working on a browser type interface. They're not using a green screen interface. That's probably the biggest challenge for IBM i customers. 

    To a certain extent that's probably true in AIX too. We don't have enough of the web user, graphical-type interfaces that are on this platform that keep people around because they think green screen, they think old. Reality is, they might be running a green screen but the infrastructure behind it is POWER8, running SAN storage, SSD, flash technology. It's probably virtualized and they don't even realize it. But it's quite a powerful system and quite a highly modernized system in the background.

    Linux on POWER is another good opportunity for customers because all of a sudden you wake up one day and you have 500 Intel-based Linux servers in your datacenter and if only you would have known that you could have invested in one POWER server, or two POWER servers, and scale that down to only a few instances of Linux on POWER. Think about the power. To me it's just simple math. Whenever you have 2,000 or 500 or 300 servers trying to manage a business, there's just more that's going to go wrong. And so if you can scale up with the Linux on POWER, that's the way to go.

    Regarding the OpenPOWER Foundation, at first I was kind of skeptical. I thought, "Okay, well what does that mean to an IBM i customer or an AIX customer?" But what it means is that IBM is spending an enormous amount of time working on technology that's going to take us and make things like artificial intelligence, and the Watson, and all those things a little more commonplace. 

    And for all organizations, we all have more information than what we know what to do with. If we can better harvest that and predict our customers' trends and purchases, were going to be so much farther ahead than the competition. And if you're doing it on IBM i you'll be able to do that with a fairly small cost of ownership, to get into some really big super-computer type technology to do that. 

    So the open source thing as part of that brings on some new players that are helping IBM to invest. Obviously IBM is a business and if they're buying up POWER9, and if I have to wait for a POWER9 processor because some large open-source type consortium partner is buying that POWER9 technology, that's good for IMB i and AIX customers because it makes the POWER server itself a very viable economic decision for IBM too.

    It's unfortunate, market wise, POWER is not known as well. But the total cost of ownership, IBM's done a great job of lowering the price to entry and then the scalability, security, and reliability. I mean it's second to none in the IT world.
