We performed a comparison between IBM PowerVM and VMware vSphere based on real PeerSpot user reviews.
Find out in this report how the two Server Virtualization Software solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The feature that I like most is the versatility."
"PowerVM's most valuable features include swift optimisation and real-time migration."
"The most valuable feature is the flexibility in terms of managing the hardware resources such as RAM, CPU, and the network."
"You can increase resources with it automatically."
"The most valuable features in this solution are you do not get degradation in the performance like you could get in other solutions. There is a physical adapter that is better than a virtual one and you can assign adapters to a VM."
"It is a complete solution."
"A valuable feature of PowerVM is a feature that is used for higher availability plus stream for posting, which is very useful. There's a flash copy feature which we are using. PowerVM itself, I know, helps us to control and manage our Oracle licensing compliance, since it is our hardware partitioning. This is very important. If you use VMware, there will be a licensing issue. This PowerVM is a hardware partitioner, which is very important for license compliance. We are happy with this solution."
"IBM PowerVM's most valuable feature is stability."
"We primarily use vRealize to troubleshoot any issues that may arise with our virtual machines, which is the main reason why we believe this solution is excellent."
"The most valuable features for me are a very easily scalable infrastructure. I can have a couple of hosts to do basic workloads. I can have a lot of hosts to do a lot of workloads. vSAN integrates my storage so I don't need an external storage SAN. I love having everything integrated in the same UI. The new HTML5 interface doesn't require any plugins anymore and it's super-fast."
"The redundancy, the failover, the ability to stay up and running 24/7, all the various tools that are in there, high-availability, DRS, are very critical to us."
"The most valuable feature of this solution is vMotion."
"The solution has high availability."
"Its DR facility is good. Within a moment, data can be retrieve from another physical location over the Internet. The speed to recover data is good."
"It's easy to use and very user-friendly."
"The installation process is very straightforward."
"The solution is quite pricey."
"PowerVM's platform build and performance could be improved."
"The licensing could be better."
"A GUI version of VIOS would be a great plus for people moving from Intel-based hypervisors."
"SRM for site recovery is a feature that should be included."
"This solution is lacking the ability to have servers act as a cluster, such as in VMware. IBM has come out with a feature similar to VMware's vCenter but it is not as mature. They need to add LPM shared-nothing feature, such as in vMotion."
"The interface is not user-friendly in places, so it could use some improvement."
"To make it a ten, I would like for them to add automation and configuration tools in order to help use the manager."
"The technical support is good. However, it could be more seamless when it comes to chat support and lower response times."
"VMware vSphere could be improved with cheaper costs."
"There are occasionally bugs or errors."
"I'd like to get rid of the Flash Client. There are still some things we need to go in there and use it for, some plugins and other things aren't supported in the HTML5."
"I would like to see the configuration simplified."
"The integration with containers should be addressed."
"The reporting could be improved."
"Where I think there is room for improvement is in the HTML5 interface in vCenter. What it lacks, for me, is integrating to VMware's other products, especially NSX."
