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.
"What they provide is way beyond the essential requirements of customers."
"It's a scalable solution."
"This solution is very stable. Much more so than similar products."
"It is very stable."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"The solution is a great all-round product. The virtualization is especially good."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"It is a single pane of glass that lets you access your hosts and VMs."
"The solution has high availability."
"The most valuable features are that it's stable, easy to use, and it's flexible."
"The provisioning setup of VMs is good."
"The speed of the solution is excellent."
"Its dynamic resource scheduling and its fault tolerance capabilities are two features that I've found to be valuable. I also like that VMware vSphere is stable, scalable, and easy to install."
"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."
"Server Virtualization is the most important feature because that helps me to utilize 100% capacity of my physical server or box. Its redundancy, uptime, or high-availability is also valuable. Storage-sharing is also valuable. In vSAN, I can utilize the maximum storage. In the physical boxes, if you don't require storage, it lies idle, but with VMware or any kind of virtualization, you can utilize the full storage."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"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 biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"This solution could be more secure."
"The availability of technical expertise with the solution may be limited in some areas."
"One of the areas creating a crash is when you are cloning."
"Sentencing has changed a lot."
"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."
"I would like to start to using NSX in the next 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."
"There is still room for improvement with the HTML5 Web Client. They are working on it, as I can see on their blog. However, there is still room for improvement in the newer features that they can push into it."
"On the older version of VMware vSphere, possibly version four, we had a feature that allowed us to backup Ziploc machines. It has not been available in the newer version such as six or seven. I have been looking for another solution to accomplish the backups but they should bring back this plugin-type tool to allow older backup capabilities."
"I would like to see a little bit more visibility regarding errors. When an error does occur, there are times where it says "Unknown error" or something to that effect, and it doesn't necessarily give you a lot of metrics. If you go online and you give a description of it, normally the VMware forums can help you find out what it is, but I'd like to see a little bit more visibility from the software itself regarding what's going on: "This went wrong, this is why.""
