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 solution is a great all-round product. The virtualization is especially good."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"It is very stable."
"There aren't any bugs on the solution."
"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."
"It is a stable solution...It is a scalable solution."
"The solution is stable."
"RHEV’s cost is much less compared to VMware."
"I like the capability of logging into one system, then being able to shift over to another system within that single pane of glass."
"The stability of the solution is excellent."
"Reduces downtime."
"It is a powerful solution that enables us to take a snapshot and clone any version of machine."
"The solution is also very simple and efficient to manage. Features that have made it simple and easy to manage include the newer VAMI for the V-center appliance, it's very easy to see what version we are at, and very easy to upgrade to the next version. The fact that we can now use VCHA at the appliance level just decreases our chance of having an outage because so many of our customers rely on the API interface for V-center."
"We have seen a performance boost because we have been able to more dynamically allocate either memory or processors."
"It gives us the ability to be running over 250+ VMs on five physical hosts and in various flavours of guest OSs."
"The ability of a running VM to be quickly relocated to another hypervisor or launched at another site via replicated storage greatly reduces downtime."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"The documentation is not as good as it should be."
"This solution could be more secure."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"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."
"The solution could use network virtualization."
"RHEV can improve by keeping pace with new features and new enhancements. They should not be halted or delayed innovation because over the past quarter the enhancements have not been as fast as they have been previously."
"The solution has a very small lifecycle."
"There should be more stability in the updates. They had an issue with the last release."
"They should improve their storage management part. vSphere has its own file system type, called VMSS, and that file system doesn't report on proper data usage or things like that. There are certain loopholes wherein it sometimes shows you erroneous data. Again, their VMSS file system, their data storage management system, and its reporting must be improved a lot."
"I would like to see more software as a service solutions."
"vSphere could perhaps be improved by more integration or better security."
"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."
"They can lower the price of its license."
"the HTML version of things needs to get a little bit better. The vSphere side of things gets a little difficult to manage; right-click, in some browsers, doesn't work as well as it used to. I'm seeing a little bit of general latency that we didn't used to get with the thick client, although it's getting there."
"vSphere itself is great when you don't need to make updates, but any time you have to touch it, unfortunately it's always the little bit of a fight to get it to do what you want."
