The availability of a solution depends on the requirement of the customer. The most valuable feature is the virtualization. You can have this one system or you can use it for many. They were using almost 120 servers within that specific service.

Active Memory Expansion allows you to compress your memory on the run time to allow you to have less physical memory available, but provision more memory to your partitions, as everything will be compressed on the fly.

It scales a lot, you can just keep on adding frames, you can add on CPUs, you get capacity on demand, you can tune the machine very easily to handle different workloads.

What we like the most is the ability to upgrade the scaling of the system itself. Whenever we need extra storage, we can do that. Whenever we need extra memory, we can do that as well. It's fast and it's available.

The scalability process should be simplified.

It does not offer the ability to run any X86 or X64 Intel architecture-based application on Power Systems. There are a lot of applications, lots of business use cases that do not support this architecture as of now. If somehow application tasks can be ported on to IBM Power Systems, that would be a big improvement.

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.

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

IBM should be more flexible with marketing or offer marketing events themselves and invite the partners to attend. That might be far more productive.
