Scalability allows very small and Fortune 100 companies to take advantage of the reliability

What is most valuable?

I think that it's reliability and availability. Also, the ability to scale and do some of the newer things with replication, with the storage. They help the Power to really stand out.

How has it helped my organization?

For me, personally, I've been around Power, IBM i, since it was System/38. It's been a long time. Personal knowledge of it is my strength. I can relay that into solutions for our customers.

What needs improvement?

For the i customers, I think that Power, the horsepower, has always been there. So, I would like to see something more on the lower end, where they would make it more cost effective for the small guy, rather than the big guy.

They need to work a little bit more with the smaller guys. Help to make it easier for them to move, to get going into the system. They need to be a little bit more competitive with the Intels of the world.

What do I think about the stability of the solution?

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.

What do I think about the scalability of the solution?

The scalability is the great thing. You go from very small systems, mom-and-pop shops, to Fortune 100 companies. That's the biggest thing, the scalability.

How are customer service and support?

We have worked with tech support for issues that have arisen. Sometimes, it's not really hardware related. A lot of times it's code related, but they're always very responsive and able to resolve the problems quickly.

How was the initial setup?

In terms of the upgrade from different versions, I think after we got past the jump from Syst ARIS, back in the day; and then, when we went from versions like 6 to 7, or 5.4 to 6, those were the really tough versions. 

Now, the version upgrades are very smooth.

What was our ROI?

We do see return on investment by upgrading from version to version.

I don't think that it's so much power, speed; it's the feature functionality. Some of the newer things that you are able to do with the newer versions, more so than the old days, when it was, "We get X amount of speed." That doesn't happen as much as the new features that are available.

For example, some of the Java things they're doing. Some of the things security-wise, there are a lot of great enhancements.

Which other solutions did I evaluate?

We are strictly IBM.

We go with Power Systems because the reliability and the availability of the systems are key. They are the best systems, as far as reliability and availability go.

What other advice do I have?

We are a business partner, so many of our customers use different versions from 5.4 up to 7.3. Most use IBM i. We do have customers that run POWER8, but we have other customers that are running on POWER5, POWER6. We're trying to get them to move to POWER8.

I would say IBM is a market leader in the server industry. It's hard because, for what my company does, as a business partner, we're not really placing too many new servers. But the customers we have are very loyal and very committed to the platform. I think that, as long as IBM takes care of the customers that they have - there is no better customer than the one you have - take care of those customers and they'll be fine.

The hardware is rock-solid and reliable but the Power Systems can be a tough sell
Pros and Cons
  • "From a reliability standpoint it has provided us with excellent performance."
  • "The lack of software vendors moving onto the platform, as opposed to fleeing the platform, is an issue."

What is most valuable?

The Power hardware is rock-solid and reliable. You can't really ask for better hardware support, software support and reliability of the equipment. It is very powerful for what it does. 

How has it helped my organization?

From a reliability standpoint it has provided us with excellent performance. 

We are in retail and we can't send technical people out to retail locations. We have to have a system that is very reliable, that will basically run 24/7, 365. In some cases, we have had the same chassis in a location for 10 years. For the most part, it takes its normal fans and power drives and power supplies, but it's the same chassis that has been sitting there running. That's why we continue to purchase IBM and Power equipment.

The Power Systems can oftentimes be a tough sell because it is much more expensive than Commodity X86 hardware. But it's not a dollars and cents kind of thing. It's the fact that we don't spend dollars and cents. It's the reliability. The fact that we've been able to use the same procedures and processes in our stores for so long is a huge benefit.

What needs improvement?

We are a special case, because what we want is the cheapest Power box we can get in all of our locations. That is not the way the industry is moving.

Cloud would be a great option, if you didn't get the worst internet connections in the world in very remote locations. That's where we are in a kind of unique situation. We have to have the processing power at a location, but we don't have the luxury of a good internet connection. In some cases, we have DSL. That goes down for days. You can't have a Cloud-based solution. You have to have something that can process on-site and retain and then batch upload data.

The lack of software vendors moving onto the platform, as opposed to fleeing the platform, is an issue.

For how long have I used the solution?

I have been using Power since the early 90's. Right now I'm using version 4, all the way up to 7+. I'm using it for AIX. I would definitely be interested in upgrading to POWER8 in the future, but it comes down to cost. It's always cost, especially in retail.

What was my experience with deployment of the solution?

We transitioned not too long ago from POWER6 to POWER7 equipment. Literally, it was just moving the Powers from one system to another. There were no questions about compatibility, it was just a move from here to here. You take care of some base prerequisites and you are done.  

OS upgrades are non issues. You just do them. Typically, we're only doing them because a vendor or an application needs it, but they work. Often there is very little downtime and no need to roll back, it just works. The same can't be said for a lot of the competitors' products.

How is customer service and technical support?

Both software and hardware support are wonderful. They are very responsive and knowledgeable. We deal with the field service technicians, the IBM CEs all the time. Usually it takes only one visit to fix the problem, which is huge. They get stuff done. 

Whereas, with some other two-digit vendors, two-letter vendors, that is not the case. In fact, we even saw discrepancies between IBM's Power and Lenovo's x86 support structure. We've actually moved some of our x86 systems away from Lenovo because the support structure isn't as good as what we were used to.

How was the initial setup?

Setup was a non-issue. The upgrades are complex, but it's easy to figure out what you have to do.

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

Power certainly isn't a great value proposition. A lot of that has to do with the fact that everybody else in our industry, from a software or maintenance standpoint, is moving away from it. 

Because of the cost I am rating them a six.

It is designed for a large workload, as opposed to a small workload. For our circumstances, and even as an independent, I can't buy a Power system to experiment on. It can't happen. You cannot buy them.

Even if you can buy them, I don't have $6000 to $10,000 to drop on a toy.  As far as I know, there is no enthusiast. There is no developer world to do that. You either have to have a big, massive system working for a corporation or you don't touch it. It's a non-starter, as far as open source software is concerned. Either you're doing it for a business, or it's not happening. That's when there are huge problems.

Which other solutions did I evaluate?

I consider other options all of the time but it's simpler to just keep going with what we have. 

We also like what Power does. It's very reliable and very powerful. And because of the code compatibility we are able to run the same programs today that we did back in 1992. That has a lot to do with it. There is no cost to upgrade the software side of things. It's just a hardware upgrade, in some cases.

What other advice do I have?

Ten or 15 years ago, software would have been written. There would have been Linux and Power, and maybe Windows, but nowadays it's Linux or it's the Cloud. You can run Linux on Power, but not for what these clients want. They want x86. They want Intel software, Red Hat or centOS on x86. 

Our software vendors, at least in our retail locations, are moving away from supporting Power. In fact, I'm shocked that they do some days. Whereas, our datacenter loads, those stay the same. Those are still going to be continuing to run what they are, because most of the major players, database systems and ERP systems, still continue to support Power.

I would not consider IBM to be a market leader in terms of servers. The reason is because if you go around and you ask people about a server, they don't talk about IBM. Maybe 10 years ago they did, but now it's HP. It's maybe Lenovo and it's Dell.  When you start talking servers, people don't think IBM. They think x86. That's where IBM dropped the ball, in some regards, because why would I think of them?

I can't buy them. I can't get them on the used market. I can't run them. I can't develop software for them. Though it's a different situation when you talk about the Cloud. That's when people tend to think more about IBM.

The system has reduced our billing cycles from days to hours; virtualization and PowerVM are key

What is most valuable?

We like the virtualization, PowerVM, the live partition mobility, and dynamically adding the processors and the memory. Also AIX. The beauty of AIX is really something to be admired. AIX is a very useful operating system. The volume management is really good.

How has it helped my organization?

I have been using POWER5, POWER6, POWER7, and then we transferred onto POWER8. We really have reduced our billing cycles from days to hours. 

Secondly, it is really good for billing jobs. It is reducing our time. We used to do billing in multiple days, now have reduced it to hours. That's great.

What needs improvement?

The HMC and PowerVM need a more catchy graphical interface. 

Secondly, the command line interfaces should be converted into graphical interfaces. It is such a complex thing in making LPARs when you are using it through a wire server. It should be easy rather than be complicated. I'll give an example of the graphical interface. The V7000 is really great. Anyone can use it, there's no complexity in there. PowerVM and the VIOS interfaces should be like the V7000.

What do I think about the scalability of the solution?

Every two years we have to buy a new server. It is kind of complex, because we have to compare it with Oracle servers. We have to do RFPs. We have to service both the servers, both the technologies, and then everything goes under pricing.

How are customer service and technical support?

We continuously engage with IBM for different service requests. 

It's good. There are a few different kinds of support available in our area, Premium Services and the Remote Services. We usually use the Remote Services. We just open a ticket and give them the logs and they give us a solution.

They are helpful.

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

No. We are already invested in IBM, so we won't go towards anything else. We have lots of investment in IBM equipment. We are certified with IBM equipment as well as for hardware and software support by IBM.

We have been using IBM the last 15 years or so, and the performance that IBM servers are giving us is really good. Secondly, in our geographical area, it's the support. IBM has got good support. And the workloads we do have in our environment, IBM has got the equipment which can handle those workloads.

How was the initial setup?

Regarding upgrades it's a tricky game. It's a complex thing, because in our environment when something is running smoothly we don't want to stop it or give it downtime. We try to keep it running as long as we can. So in this way we sometime miss the upgrades, we don't upgrade it. But we are now focusing on the upgrades in a timely manner, rather than waiting for years and years. We are working on that.

What other advice do I have?

My rating of nine out of 10 is for the hardware. However, the software still has lots of issues. For example, we need to upgrade the software very frequently, so I'd give it seven out of 10.

In Pakistan, IBM is a market leader, and to maintain that position the main thing is support. If the support guys are good - the people who are managing the accounts for enterprise organizations - are good they are very much in contact with the organization, keeping it informed about the new technologies and the new offerings. These certainly can help in keeping IBM's position right now in the server industry.

We use it to virtualize everything; oversubscribing CPUs saves us significant money
Pros and Cons
  • "The virtualization and the quality you get from it is one reason we like the solution."
  • "If you take advantage of some of these real advanced features, for oversubscribing as an example, it's not supported on Linux on Power. So that stops us, in particular, from going that way."

How has it helped my organization?

I think the biggest driving factor for the bank is the cost, the cost-performance profile, it's better than anything else.

If you virtualize, Power hardware allows you to oversubscribe CPUs, and we take a big advantage of that for the bank. We save the bank millions of dollars by oversubscribing, because we have probably 700 DevOp servers, where they develop software. The developer might have 40 or 50 servers. They don't run them all at the same time, maybe three or four of them do. So we give those 40 or 50 servers just a couple of CPUs. We way oversubscribe. In fact, IBM-ers raise their eyebrows when we tell them our oversubscription rate.

What is most valuable?

The virtualization. Power was the first solution to have it. Now everybody does virtualization, like VMware, etc. But Power was there a long time before everybody else. 

We virtualize everything, we're about 95% virtual. The virtualization and the quality you get from it is one reason we like the solution.

What needs improvement?

Regarding new features, we like where it's going. I really can't think of something newer that they are not currently working on.

Except for Power on Linux. The licensing for software products, including IBM's products - it costs you more to run Linux on Power than it does AIX. That's something I would like to see them improve. We would like to go to Power Linux, but all the software that we are using - and I'm talking like IBM software, like Webster - they don't let you oversubscribe the software. It's not cost effective.  

If you didn't know better, if you didn't do these things, you probably wouldn't care and you would put Linux on Power. But if you take advantage of some of these real advanced features, for oversubscribing as an example, it's not supported on Linux on Power. So that stops us, in particular, from going that way.

What do I think about the stability of the solution?

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.

What do I think about the scalability of the solution?

No issues. And we take advantage of that scalability. I have a few frames where we have over 200 servers on a frame.

How is customer service and technical support?

We have IBM support. We are a big IBM user. In fact, we use their support for Middleware. They're excellent.

How was the initial setup?

I'm not a good person to ask. This is what I do. To me it's easy, I think it's easy to learn. I think the one problem new people have is - and this isn't just something that relates to IBM - the phraseology is different. So something in VMware might mean something different in the Power world. The lingo, there's some new jargon, and new acronyms that you have to learn. But once you get around that, you realize this thing is the same as this other thing on another system; just a different word.

What was our ROI?

In terms of a move from version to version, and the return on investment from a move from POWER7 to 8, or from 5 to 6, I would say the software has gotten friendlier, more robust, easier to use, easier to upgrade. I think the advantages you get from going to POWER6, POWER7, POWER8 are a bigger thing than going from AIX 6 to 7.

On the hardware side the upgrades are great. With POWER8 we picked up SMT8, and that made a big improvement. If you have applications that can take advantage of it - we run mostly IBM software - so of course the software is enabled.

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

The cost model is great. There is so much built in to the technology, that if you know how to use it you can save yourself a lot of money. Again I'll go back to what I said earlier: We're saving millions of dollars on software cost by oversubscribing. I know a lot of other users that don't do that. Either they don't understand how some of the technology works, or they're afraid to try it. All the advanced features that are built into this platform we use.

Which other solutions did I evaluate?

To start out, I actually put the first Power systems in the bank. The first applications we were using, they only ran on Power. There's one application, that we call "wire transfer" - banks use that to transfer money to the Federal Reserve - and it only runs on AIX Power. That's what really got us going. Then, over time people realized it was a better. We used to be an HPE shop and over time we proved that we were better than HPE, and we just retired our last HPE server.

What other advice do I have?

We're on all versions of Power. We just retired a POWER4 box, but we have POWER5, 6, 7, and 8. We have all these versions primarily because we're a bank, and we have a lot of old applications. It's hard to get people to upgrade their applications so we can upgrade their hardware. We use it strictly for AIX.

We're running about 1200 servers right now. I have a couple old POWER5 and POWER6 frames, as I said previously, but most of our stuff is on POWER8. We have about 18 870 enterprise servers, and that is where the bulk of our stuff is. We are trying to get everything over to the newer stuff.

Power uniquely positions our bank in the industry because we are almost 100% virtualized, so we're cloud-ready, if you will. In fact, we view our AIX environment as a private cloud at the bank. That is one of the big things. 

And the Power solution is a lot more customizable that many of the others. We have some unique infrastructure things at the bank that it fits perfectly.

In terms of some people saying they want less "green screen," less command line, they're talking about UNIX, and historically UNIX is a command-line type of interface, a text interface. We can do a GUI in AIX, and most people don't use it. In fact, the only time you see a GUI is when people are installing software, because Oracle or DB2 has a GUI install interface, so you have to fire up a GUI.

I think IBM is a leader in the server market. I'm an old guy, back when I got into AIX, the Sun servers - the big Sun 10Ks and 18Ks, the HP Superdomes - those were all the enterprise servers, those were the servers of choice. Then came Power AIX, now they're number one. There is no more Solaris. HPE is struggling, they finally quit making their own hardware. They are doing x86. The Power hardware is just so much better than x86 hardware.

TCO is highly competitive, if not always the best, especially for a per-core priced database

What is most valuable?

We like the resiliency, we like the flexibility, the speed of the processor. 

How has it helped my organization?

It brings reliability. Rarely do we have failures.

TCOs is highly competitive, if not always the best, especially if you're running a per-core priced database.

What do I think about the stability of the solution?

No issues. Very stable.

What do I think about the scalability of the solution?

Highly scalable. No issues scaling.

How is customer service and technical support?

I'd say they were been better in the past. Obviously it depends who you get. You need to know how to drive your support calls to get maximum effectiveness but, on a one to 10 scale, I'd give them a six.

They could improve responsiveness, ownership of problems, and technical acumen on the first level.

How was the initial setup?

Hardware migrations: logical partition mobility. Move it right onto the next platform.

Software x updates are pretty straightforward. I don't have much experience with i. And Linux is Linux.

What was our ROI?

In terms of the AIX, we are  definitely seeing a return on investment from moving from original versions of Power to POWER8, in performance. And we're definitely getting a per-core gain by moving to POWER8. In addition, the whole I/O speeds in general are improving.

Which other solutions did I evaluate?

We've primarily beem a Power shop. There have been other considerations, for x86. We were sing Linux on Intel before Power. We chose IBM because of total cost of ownership. 

It's always been the platform for enterprise applications and go-to production systems that need that sort of reliability to run. 

What other advice do I have?

We're currently working with POWER7 and POWER8. We use it for AIX, IBM i and Linux.

I would absolutely recommend Linux on Power. I believe we're going to expand our use of Linux on Power.

I think IBM is a market leader in servers. To maintain that position I'd say the Open foundations that they've created are a good way of pulling in a broader base of users and technology. Keep improving around those arenas to get better.

Regarding the OpenPOWER Foundation, I think it brings a credibility to the Linux platform, and it allows customers to see that enterprises are serious about using Linux and exploiting its functionalities on Power.

We don't have to concern ourselves with the chipset, hardware, or software, it runs itself

What is most valuable?

The chip itself is a higher performing chip than x86 chips, and we get the IBM hardware on top of it.

How has it helped my organization?

To not have to manage the chipset or have the software or hardware really be a concern for us. It just runs itself.

What needs improvement?

This isn't really related to Power, it's related more to the OS system level, but instead of chasing the industry they should lead the industry. A lot of the things that are being deployed on Power now are things like Node.js and things of that nature. But they're chasing the market, they're not leading the market.

For how long have I used the solution?

Since the beginning.

What do I think about the stability of the solution?

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

What do I think about the scalability of the solution?

The scalability is phenomenal as it scales up. I'm here at the Power Conference to learn about how I can possibly scale out with the Power systems.

How are customer service and technical support?

They are very knowledgeable but there's some bureaucracy as far as the time to respond goes, as far as getting back to us with what we need.

They tend to request logs an awful lot when the solution doesn't always warrant that.

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

We started on a System/36 and grew into the AS/400 and we're still going with IBM i. It was always IBM because a lot of our code is written in-house. We're definitely planning on moving up to POWER 8 in the future.

How was the initial setup?

The big version releases, as far as 5 to 6, and 6 to 7 were complicated. All the point releases were fairly straightforward.

What was our ROI?

In terms of the upgrades from previous versions, we definitely see a return on investment. We get more processor, more CPW, and it's basically the same price.

What other advice do I have?

We are currently using version 7.2 with IBM i only.

I don't know that Power uniquely positions our business, it's more of what we do as a business to position ourselves, as far as our commitment to customer service and customer care.

I think they're definitely a leader in the server industry as far as Power goes. From what I've been hearing at this conference, they're doing a lot with the Power chip to help maintain that position. So, I'm happy with it.

High performance means fewer machines, fewer servers, and scalability is great

What is most valuable?

The performance, the resiliency, and in the capacity that IBM provides the customer, that you can support old versions like, for example, AIX 5.3/ 6.1 in the new versions.

How has it helped my organization?

In our case we are a business partner, we sell solutions. But I think what our customers appreciate most is that they can save space, since Power is high performance. You can have fewer machines, fewer servers and good performance in your environment.

What needs improvement?

Since the cloud is so in demand right now, there is a feature that VMware has which is vMotion. I would like this with PowerVC, NovaLink, PowerVM. I would like IBM to improve that feature so that we can sell it to our customers and improve their satisfaction.

IBM is definitely a market leader in servers but to maintain that position it needs to improve how the information gets to the customer. Sometimes IBM is very good at doing new things but nobody knows about it.

For how long have I used the solution?

We have been using Power since before it was named Power, RS/6000 and the like. We've worked with POWER more than 10 years.

What do I think about the stability of the solution?

We had issues, but not so big. Most of the time they have been simple things, performance, microcode updates and things like that; but never a big issue that I can recall.

What do I think about the scalability of the solution?

I think scalability is wonderful because you can get start with a small machine and you can grow as you want.

How is customer service and technical support?

In our regions it's Argentina that provides the service to us. It's very good. They always help us.

How was the initial setup?

It's straightforward, it is very simple.

What was our ROI?

When it comes to upgrading from POWER7 to 8, or other upgrades, there can be a return on investment because you can use some parts of a POWER7 machine and build them in to a new POWER8 and I think it's a cost savings for our customers.

I don't know too much about licensing or prices or the like, even though I get involved in the configuration, presales and that kind of thing. I am just hoping to see what is coming with POWER9.

Which other solutions did I evaluate?

We haven't considered any competitors at the moment, but we do have competition back there in my country, of course. We chose IBM because of its performance, resiliency and the capacity you have to make LPARs. It's very good.

What other advice do I have?

We have POWER8, POWER7, we still have some POWER6 and some POWER5. We're using it for AIX.

We run our financial environment on it and performance is key; we can't miss getting quarterly numbers out

What is most valuable?

It just works. I don't know how else to explain it. We don't have a lot of issues with it. It handles our enterprise systems well.

How has it helped my organization?

Performance. We run our financial environment on it and there are key dates you always have to hit. Performance is key there, when we close the quarters and the like. You can't risk missing dates for getting your numbers to the street.

What needs improvement?

I could see a benefit in some organizations if licensing were more cloud oriented. We're not big in the cloud yet. I guess at some point that would probably help.

Pricing has room for improvement. It's definitely more competitive now than it was. That was an issue we had a while back where you'd look at the cost and it was just so much more for it. It was a hard sell.

What do I think about the stability of the solution?

No issues.

What do I think about the scalability of the solution?

No issues.

How is customer service and technical support?

Support is good. I think it used to be much better. Sometimes it takes too long to get to the right person. You have to go through too many levels to get to the person you need, that has that skill set. I understand that, there's level-three, and you have to escalate and it takes time.

How was the initial setup?

Straightforward.

What was our ROI?

We have been seeing a return on investment in the moves from version to version due to better performance and they cut the licensing costs down. 

Which other solutions did I evaluate?

It was only Power for the most part. We started with it a long time ago. The rest of our environment runs on Linux, SUSE and Redhat for application web servers.

What other advice do I have?

We use it for AIX. We actually just got P850s but they were refreshed.

I consider IBM to be a market leader in the server industry but to maintain that position pricing is the main thing, to be able to compete with Linux. It's difficult on x86. But on the side of trying to sell it to management, they just look at costs a lot of the time and it's a tough sell; they don't really deal with the reliability of the system's performance.
