Likelihood to Recommend 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.
Read full review RHEV is well suited for organizations that need a cost-effective and flexible solution for their environment. As its vendor-independent software, easily install on any type of hardware. RHEV provides a GUI interface to manage the software, which makes the management of the software easier for the end-user. RHEV is best for non-production or less critical applications. RHEV can be easily integrated with other REDHAT software.
Read full review Pros I love how it supports a mix of operating systems protection of our sensitive energy data and ensuring compliance with industry regulations. It provides a flexibility that ensures that we can accommodate increased workloads without a complete overhaul of our infrastructure. Read full review RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon. Red Hat distribution integration is seamless as it is integrated into the kernel. OpenStack support enables more customized VM templates and network configuration control. Read full review Cons 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 Then it became outdated and support for it ended as the language continued to evolve.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. Read full review 1- RHVM API is pretty slow, especially after creating a VM it is not possible to retrieve the VM details (i.e VM's MAC Address) fast enough, where we need to place a pause in our Ansible Playbook, make the automation process slow. 2- RHV is still using collected to monitor the hypervisors which is deviating from Red Hat policy for other RHEL based applications to use PCP to monitor, which is richer in features. 3- It will be great if it is possible to patch the hypervisors using other tools such as satellite and not only via RHVM. 4- In the past Red Hat used to present patches in the z release (i.e. 4.3.z), and features in the y release (i.e 4. y), but starting from 4.4 that is mixed together wherein the Z release you get both patches and features, that is not good because that requires a lot of time to test when we patch as it includes features as well. 5- Engineering team has to be more reactive when new feature is requested.

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.
Read full review 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
Read full review Reliability and Availability 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
Read full review 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.
Read full review Support Rating 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.
Read full review Implementation Rating 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
Read full review Alternatives Considered Power server do not need a stack of software for viruses, spam and others... Power server do not need to have release often power server are much more strong then other manufacturer Power server do not need to restart offen
Read full review RHEV is an excellent product, includes more features, is less expensive, and has rock solid reliability and is backed with the best Red Hat Support in the industry. RHEV uses KVM under the hood which is used by all the big players in the industry (AWS, Rackspace, etc) to lower their overall costs and improve efficiency and profits and that's why RHEV is an excellent solution!
Read full review Scalability 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.
Read full review Return on Investment In the event of a crash, IBM Power servers offer a variety of simple options to recover the operating system. With the flexibility offered by IBM Power servers, the production business can be improved by making the most of its physical servers. Read full review RHEV has provided a positive ROI as our customers are not experiencing as many outages during maintenances. We have not experienced any catastrophic failures as a result of vsphere losing connection to the ntp. There has been a level of stability in our environment that was not previously experienced with our previous vendor. Read full review ScreenShots
