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.
"RHEV’s cost is much less compared to VMware."
"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."
"One of the most valuable features of this solution is the popularity of the OS."
"The most valuable feature of this solution is the support portal."
"This solution is very stable. Much more so than similar products."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"It is very stable."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"Using vSphere we have virtualized over one thousand servers and this gave us management, cost and datacenter space advantages."
"We scale it both vertically and hortizonally. We have many data centers on it."
"The most valuable feature of this solution is vMotion."
"The performance is efficient."
"Tech support is very knowledgeable."
"Technical support is helpful and always available."
"Virtualization, VDI and application publishing are the most valuable features of VMware vSphere."
"The free ESXi hypervisor was a great way to get started, as it allowed us to introduce virtual machines so that users could start to experience the advantages."
"It would be better to have more patches, especially kernel-level updates, live and online so that we can keep the business up and running during this period."
"The availability of technical expertise with the solution may be limited in some areas."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"The solution could use network virtualization."
"The UI should be more interactive with additional features."
"The solution has a very small lifecycle."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"The hardware cost is high."
"The biggest room for improvement would be just simplicity. It is very intuitive, but it needs somebody with a lot of IT background."
"The biggest problem in this solution is the incompatibility of some of the features with some of the drivers installed on servers. For example, if I want to install vSphere on an HPE server, the driver is really different from a Dell server or a Fujitsu server. I need to download different drivers and install them manually, which can be improved by VMware. They can offer a special image to match different servers. We face different problems when we install vSphere on an ESXi server and have different drivers on the storage. ESXi cannot detect different kinds of storage, and they should improve this. We updated our existing version to vSphere 7 in a private environment, but it seems that this version is not very stable. We are facing issues with restarting the host. In earlier versions, such as vSphere 6 or 6.5, we didn't have any such problems. It would be good if VMware can offer specific applications for mobiles to enable us to control the management of all servers by mobile. They should also improve the vCenter GUI because it is currently not compatible, and there are a lot of problems. Some of the options do not appear well in the browser. VMware should spend more time resolving the problems in the GUI."
"I would like to see DRS for the GPU machines."
"As we introduce the DevOps culture, we need to make sure that the principles and tools used to support this approach can be easily integrated and interoperated with the vSphere environment with no (or less) redundancy in tools and functionality."
"The initial setup could be better. It manages all the setups, but it's not very straightforward, and it takes time."
"The performance of the solution could be better and there could be an extra level of security."
"It needs to integrate better between multiple modules."
