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.
"There aren't any bugs on the solution."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"What they provide is way beyond the essential requirements of customers."
"It is very stable."
"The most valuable feature of this solution is the support portal."
"RHEV’s cost is much less compared to VMware."
"It is a stable solution...It is a scalable solution."
"This solution is very stable. Much more so than similar products."
"VMotion is the biggest feature. It gives us the ability to move things on the fly."
"vRealize Operations Manager is the most valuable feature, but it is not embedded in vSphere; it is a part of vSphere. It is used for forecasting and checking the consumption of CPU, memory, and other resources. It has the capability to do the forecast based on the history and give advice on consumption. VMware vSphere is easy to use and easy to implement. Its learning curve is not sharp. Any engineer with little or medium knowledge of hypervisors and virtualizations can implement vSphere with a few clicks."
"Visibility: We can easily pull reports and give access to other people to look at specs or performance metrics."
"It has high clustering and availability features. These features are not found with other hypervisors."
"The most useful features are ESXi, DRS, Auto Deploy, and the Lifecycle Manager."
"Having a virtualized infrastructure and being able to bring up Windows, Linux, and VMware within a virtualized environment brings more technology into the classroom. Without it, we couldn't do what we do."
"VMware vSphere helps us in not wasting resources like we did when we were using physical servers. It changed our whole environment."
"It is fairly easy to use and has enhanced security."
"While everything needs improvement in some way, I have no specifics."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"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."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"The documentation is not as good as it should be."
"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 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."
"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."
"We've been using vSphere on Windows 7, and it had less fluff associated with ThinApp. Currently, with Windows 10 version that we have, it adds a lot of bulk to ThinApp. We have offices spanning across Canada from the east coast to the west coast. A ThinApp that is roughly around 400 MB in size would take minutes to open up. With Windows 7, the same ThinApp used to be close to 75 to 80 MB in size. So, I'm really not happy with the extra fluff that is bundled in Windows 10. It really messes things up for us at times."
"The solution should be more secure."
"The technical support is poor. We are in Australia, but we do not have the same level of support as the US and Europe."
"The web user interface can be a bit clunky from time to time, so there may be some room for improvement in that regard."
"I know VMWare has this Operations Manager. I know that it comes at a price because VMWare normally wants to charge for everything in the software. But I'm not seeing all the features of the Operations Manager. I only see a few features. If all the features can be included in one package, that would be good."
"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."
"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.""
