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 stability is the most valuable aspect of this solution. IBM is the most powerful and stable platform."
"PowerVM's most valuable features include swift optimisation and real-time migration."
"The feature that I like most is the versatility."
"Active Memory Sharing dynamically reallocates memory of running partitions based on changing workload demands. The memory for the pool is carved out from Physical memory and is made logical memory. The said memory is not available to be assigned to partitions as dedicated memory. A min, max and desired as well as weight is assigned to the memory of each lpar to help hypervisor make a decision in case a condition where priority is to be given to a certain lapr to use the memory form shared pool."
"The most valuable feature is the flexibility in terms of managing the hardware resources such as RAM, CPU, and the network."
"Technical support is great."
"Managing other operating systems is also straightforward with IBM PowerVM."
"The valuable feature of the solution is the technical aspects, focusing on elements like processor infinity."
"It helps us with TCO."
"The performance of VMware vSphere is good."
"Scalability is the big advantage of it. The product itself allows us to scale on the fly as we need it, and plan for the future."
"The ability to monitor resource utilization."
"We are able to increase the density of the virtualized servers and, with the increased density we have a lot of page sharing as well as memory sharing."
"We don't have any downtime because it was built right."
"Most valuable features are quick provisioning, High Availability, and DRS for balancing workload."
"Server consolidation. Getting rid of our physical servers and going virtual is saving us some money in overall rack space."
"IBM PowerVM could improve the price because it is expensive."
"I would like for IBM to be more focuses on the cloud."
"To make it a ten, I would like for them to add automation and configuration tools in order to help use the manager."
"The performance should be improved."
"SRM for site recovery is a feature that should be included."
"The product's pricing could be less expensive compared to other competitors."
"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."
"Any improvements that can be made in the interface will go a long way to helping us work better."
"It would be nice to see it a little more tightly integrated with the patching solution so you could do it in one pane of glass. Right now, you have to jump back and forth. It's still not difficult, but you have to jump back and forth to do your update definitions and then go back and actually do the updates themselves."
"Sentencing has changed a lot."
"There are occasionally bugs or errors."
"Its price should be better. Their support should also be more customer-friendly, and they should train people like us so that we know more about the latest technologies and features. If there is some program and drive from their side to teach us, it is definitely going to help us. Pricing and support are the most important features for mid-level companies. We are not implementing this solution for big tech companies."
"The VMware vSphere app is faster, compared to its web-based client. The web-based client is very slow, freezes, and is challenging to use."
"Here in Egypt, we would like everything free. So if you give us the license for free, we would be thrilled."
"To manage it properly, you have to know this product really well."
"The quality of support could be better."
