Likelihood to Recommend IBM Power VM is well suited in a large environment where we have to run multiple virtual machines on a single hardware and utilize the hardware more efficiently. It directly saves the cost of the organization. Due to the high licensing cost of IBM Power VM, it's less appropriate for smaller, less critical applications that do not need a lot of performance.
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 Offers a very granular virtualization of each core. Provides a quick and easy environment to build and maintain. Is rock solid and provides a reliable production environment. 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 We have yet to upgrade VIOs from 2.2.0 to 2.2.3 which will provide the more GUI centric management, however, making the VIO servers easier to manage would be one area. I think this is done with the latest versions of HMC and PowerVM. More real-time and historical performance reporting. 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. Read full review Likelihood to Renew The product works. It provides the proven environment to support IBM's primary operating systems that run on the IBM Power processing systems. This by extension includes the IBM various storage products that work within that environment. It has proven to be seamless as the environment has grown and as various new products and version updates have been added. As with most IBM products, the support is excellent.
Read full review Alternatives Considered IBM PowerVM is the best and most stable product in the virtualization market. It gives the best performance with IBM Power Server, especially its best solution, where we have to run critical applications and save applications licensing costs. It provides a lot of good features like LPM, shared processor pool...etc, which makes the environment more flexible.
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 Return on Investment We are able to run several LPARs on one frame, which means we do not need to buy as many physical servers. That saves on floor space, power, and heating and cooling of the data center, among other things. Using LPM allows us to do maintenance on a frame without impacting the LPARs, giving us greater uptime. 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
