We performed a comparison between RHEV and VMware VSphere based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Based on the parameters we compared, VMware VSphere got better user reviews. One major difference between the two solutions is that users say that RHEV’s scalability is not great.
"The initial setup is fairly straightforward and well-documented. The process is very similar to its competitors. The success of your setup depends on how well you plan."
"The solution has a good licensing module."
"It is a scalable solution."
"The solution is stable."
"It's a scalable solution."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"The solution makes migration easy."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"The virtualization is set by itself. vSphere is the best way to have a non-host based fixed solution. We always try to find an agnostic environment where we can restore agnostics or just say, "I need resources, capacity." That's why VMware vSphere in particular, has been the best in the past but now also with the evolution of their product. Nowadays, you don't have to use any STEM infrastructure anymore because the bandwidth and the land speeds are getting steeper."
"This solution is very stable. It's scalable and simple to set up."
"We don't have any downtime because it was built right."
"The solution saves cost."
"VMware vSphere has useful tools for management and support."
"For me, the most valuable feature would be the EVC, but EVC has been changed to be per-VM which makes it possible for us to migrate the VMs to cloud and not take into account what hardware they're running on. Also, a big improvement from the previous version is that I'm now able to schedule backup for the VCSA. That is, in my opinion, a huge improvement. The last thing that I think is really great is, I'm not able to boot the OS and not the entire server. That's going to save me a lot of time."
"VMware vSphere has helped us create our infrastructures and provide services for our customers."
"It is highly scalable. We can add new hardware and expand the infrastructure easily."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"The solution could use network virtualization."
"In comparison to VMware, this solution isn't as stable. We're testing it right now, and we're not trusting the stability of the product."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"The UI should be more interactive with additional features."
"The support is tricky in a few places. We're facing some challenges within Malaysia where we don't really have the system integrators available who can provide extended support. When we need personnel on-site, we can't get them."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"The availability of technical expertise with the solution may be limited in some areas."
"Security and patch-related items need improvement."
"The vSphere Client always feels slow, and/or like it doesn't keep up with what I'm trying to do. So I usually use the thick client most of the time."
"I would like to see the UI incorporating all of the functionality that the thick client had."
"The price could be better."
"There are some challenges around ESXi hosts — converting them into VMs."
"The only improvement that is needed that come to mind are improvements in the vRealize Automation and vRealize Operations management simplicity."
"They should make it more efficient and stable."
"There was a time we lost the password for the ESXi and we had to do a hardware reset. At this point, we had to fill up the ESXi from the bottom up. I am not sure if there was another solution to this problem but it took a long time."
