It really depends on each client and what they have regarding hardware and software. If the client has a partnership with IBM or is using IBM software, usually they go with IBM hardware. If the client is a Dell partner, it usually goes with Dell hardware running Linux, and so on.

I'd strongly recommend IBM Power servers to anyone who has the budget for it. A Power Virtual Machine, what is generally called FlexTB VM, can support as many small VM of 256GB, and scale up to 32TB on the fly. If IBM recommended architecture is combined with your organizational reference architecture, then forget about running into unplanned downtimes.

Most of the time, server utilization is reliable and stable during peak times. Truly amazing, this product offers a lot and gets it done in no time without any confusion.It is reliable, too accurate and the performance is top-notch. It seems to be competitive in all virtual energy systems and its connectivity is also good. It's available at a low cost, but it's enough to have as many low-cost, more efficient systems as possible. It's a minor thing, but very rarely, it can cause work interruptions while it can get stuck due to more frequent use such as restless work. These power servers are very efficient and really help when things go wrong. I am using this product to retrieve data much faster.

Cons
IBM
  • A solid IDE for editing programs. SEU was simple and solid. Then it became outdated and support for it ended as the language continued to evolve. That's fine. But RDi is expensive and shaky at best, and VS Code, while free, is severely lacking even the modicum of features RDi has.

  • It would be good if IBM could demonstrate more use cases for Z to potential clients
  • A migration strategy from Open Systems to Z would be helpful
  • Any additional marketing to could explain the benefits of Z/Linux, especially now that RedHat is in the mix.

This is one of the best systems on the market. You can have Flash/Copy which created another LPAR to look like the system you are copying. This takes seconds and not minutes. Then you can use BRNS to do full system backups nightly with no downtime. I am ready for us to upgrade to a Power 10.

Usability

They are very easy to set up and use once you re knowledgeable enough to deal with it. They are continuously enhance the user experience on the HMC and operations on the systems. Once setup it's like a beast, going on and on. I have experience with servers that are not being rebooted for more than 1000 days

Reliability and Availability
IBM
In all of the years I have used various Power System, I have never had any problems at all. Even when hackers were attacking our email servers and many users PCs, the IBM Power System came out completely unscathed. I haven't even had any application errors that were able to take the system down. Nor have I ever experienced an unplanned outage

Performance

The IBM Power System is built for integration. It supports multiple operating systems and you can run multiple OS's on the same box with no problems at all. It also supports a number of open source languages such as PHP, Java, Python, and Perl which helps you continue to grow and integrate with lots of other systems.

Performance is a major part when you configure your system. IBM has many tools to study your system and suggest the appropriate configuration. With the right contract, you can add processing power dynamically and remove it when no longer needed

Support Rating
IBM
On large-scale systems, the rating would have been 10. However, I have seen some cases in more rural areas where the IBM onsite support is not as available or of the highest quality as in the past. For software support, there are sometimes instances of language barriers.

Support is usually superb, only occasionally dropping to very good. We participate in some of the CD (Continuous Delivery) aspects of z/OS, IMS, MQ, and DB2.

Systems are robust and you need to know exactly what your are going to do with them. There are multiple configurations possible and you need to gather your requirements first, before going on with the implementation. Tuning is a must before migrating production systems

IBM Z is the best storage solution as it provides the best in class data protection with the cryptographic hardware keys, no loss in data while migration, and a user-friendly interface that makes it easy for develops to understand and has less of a learning curve. This makes it well above the competition.

Scalability
IBM
This system can work in a small factory with a few users and easily scale out to thousands of users. It is truly amazing on how much you can throw at this box and it will just keep humming. It is great for use across multiple departments and even across multiple corporations. I worked at one company where we were hosting multiple corporations on just one large Power System and had ZERO problems.

If you need more processing power, just add more CPU's or memory. The largest system can have close to 200 CPU's and 40 TB of memory. If that is not enough, you can add more physical computers, and connect them using a sysplex
