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 makes migration easy."
"There aren't any bugs on the solution."
"The solution is a great all-round product. The virtualization is especially good."
"It's a scalable solution."
"The solution has a good licensing module."
"What they provide is way beyond the essential requirements of customers."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"Customers are moving to open source and Red Hat is the leader in this particular space. I think customers feel more confident running Red Hat Virtualization than VMware."
"We have the possibility to move workloads to different locations."
"The most valuable features are its flexibility and the ability to move workload."
"Gathering all of the hosts together to create one single pool across the enterprise is a terrific feature."
"vSphere does offer quite a bit of security stuff built-in. It is nice to know that we can have the virtual machines encrypted, so that if somebody were to get a hold of any of those files, we don't have to worry about them actually being used."
"It's easy to use and very user-friendly."
"The installation process is very straightforward."
"It helps to automate the data replication and DR (disaster recovery)."
"The most valuable features of the solution are the overall virtualization technology and the new features that allow you to move servers from one system to another."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"When we do a direct comparison, then obviously VMware does better in terms of having Fault Tolerance and doing active disaster recovery and these kind of things. This is something that can be improved within Red Hat."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"The availability of technical expertise with the solution may be limited in some areas."
"The documentation is not as good as it should be."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"I heard that there are big differences between Red Hat eight and seven, but it's still quite difficult for me to judge it. I found it a bit more difficult to manage than version seven, which was much easier. In term of features, though, it is still not yet clear which is better. I have no clear idea of which features need to be changed at the moment."
"The cost can be better."
"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."
"Archiving, exporting, and backing up need to be improved for this solution, because they're slower than expected."
"I feel that the scalability of the solution should be improved."
"From my point of view, my advice is to design the solution properly the first time."
"The initial setup is a bit complex."
"There are some limitations with the solution regarding migrating."
"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."
