We performed a comparison between IBM PowerVM, RHEV, and VMware vSphere based on real PeerSpot user reviews.
Find out what your peers are saying about Proxmox, VMware, Microsoft and others in Server Virtualization Software."The tool's performance is top-notch."
"The most valuable feature of IBM PowerVM is the performance of the database workload."
"It's in English, so its exceptional qualities make the control environment more flexible, easier, more stable, and easy to recover after issues."
"The stability is the most valuable aspect of this solution. IBM is the most powerful and stable platform."
"You can increase resources with it automatically."
"The case fileserver on the web server is the most valuable feature."
"It's scalable. Whenever we buy another product other than hardware, it's easily integrated into the virtualization software that we download."
"We always recommend PowerVM to our customers; it is better than most solutions."
"It is very stable."
"The solution has a good licensing module."
"Red Hat is the most stable system."
"The most valuable feature of this solution is the support portal."
"The solution is stable."
"The most valuable features of RHEV are all the tools, such as virtualization, management of cloud platforms, and integration of container environments. The solution has good compatibility between virtualization, content management, and cloud management. Having the full set of these tools is the advantage of it."
"One of the most valuable features of this solution is the popularity of the OS."
"There aren't any bugs on the solution."
"vMotion is one of the most useful features, which helps to provide both flexibility and High Availability. With new versions of vSphere and vCenter, it is still improving (e.g., vMotion across vCenter Servers and virtual switches)."
"It is a powerful solution that enables us to take a snapshot and clone any version of machine."
"VMware vSphere is a very stable product."
"One of the most valuable features of this solution is the ease of deployment. It's also user-friendly and has been on the market for more than a decade, so it's a leading technology in hypervisor solutions."
"An easy way of providing near-zero downtime services, the operation of the instances between clustered services, and providing the projected SLA for our customers."
"It helps to automate the data replication and DR (disaster recovery)."
"It gives us the ability to be running over 250+ VMs on five physical hosts and in various flavours of guest OSs."
"VMware vSphere has very good applications and services."
"Any improvements that can be made in the interface will go a long way to helping us work better."
"To make it a ten, I would like for them to add automation and configuration tools in order to help use the manager."
"The cost of this solution is high."
"I would like for IBM to be more focuses on the cloud."
"I don't know whether this has been trialed already, but IBM should give us an alert when we reach seven or eight failovers so that we can automatically switch it to manual mode. That would be great because if we cross the 10-day licensing limit, we have to pay a hefty license cost to Oracle. If IBM could view that feature, it would be helpful in license compliance."
"The performance should be improved."
"IBM PowerVM could improve the price because it is expensive."
"The hardware licensing model could be improved because the licensing model is a bit different from the standard hardware procured."
"When we do a direct comparison, then obviously VMware does better in terms of having Fault Tolerance and doing active disaster recovery and these kind of things. This is something that can be improved within Red Hat."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"The documentation is not as good as it should be."
"I heard that there are big differences between Red Hat eight and seven, but it's still quite difficult for me to judge it. I found it a bit more difficult to manage than version seven, which was much easier. In term of features, though, it is still not yet clear which is better. I have no clear idea of which features need to be changed at the moment."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"We hope that Red Hat can produce a paradigm edition. We are looking for paradigm computing and paradigm storage. Its scalability can be improved. It is not easy to scale, and we hope that Red Hat can provide a more scalable system. They should also provide local service and support. Our customers are looking for a good software vendor to provide professional services."
"The management could be simplified for base-level customers, but of course, it would be difficult to match all customer needs."
"The license fee could be more affordable."
"These days we have an environment where we are often using clouds as well. A solution that would be a little more cloud-aware would be really helpful. I know there is a product from VMware that is more specifically for the cloud, but it would be nice if VMware Cloud Manager would be cloud-aware. It would simplify certain processes."
"My biggest suggestion would be some kind of a mechanism - and it's almost an AI-type thing, a Siri/Cortana - for where to find how to do certain things. If there was the ability to just type in a basic question and say, "How do I change the VM settings for this?" and it could bring me right there, that would be really awesome."
"The solution could be more stable."
"As far as the web client goes, one of the frustrating things is that it's dependent on different browsers. One day it may work with only a given browser or there may be issues with Flash. So I look forward to being able to use the HTML 5 client."
"The initial setup could be better. It manages all the setups, but it's not very straightforward, and it takes time."
"It would be great if the free version included a management tool that was a scaled-down vCenter Manager."
