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 most valuable feature of this solution is the support portal."
"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."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"Stability and speed are the most valuable aspects."
"The solution has a good licensing module."
"Red Hat is the most stable system."
"RHEV’s cost is much less compared to VMware."
"The solution is stable."
"It helps to automate the data replication and DR (disaster recovery)."
"Some of the most valuable features are: the ability to Snapshot so that when we do updates we have a layer of protection for simplified rollback; the replication that we can leverage for data center failures and data center downtime; the ease of migrating workloads from physical device to physical device for maintenance that we have to do on physical servers."
"We have removed the need for backups and going to the office at three in the morning to change a server. I do everything during my business hours. It gave me my life back."
"I have found the Storage vMotion feature to be the most valuable."
"The solution has many valuable features. Virtualization is flexible and it has simple clustering. However, the most important feature is the ability to move between VMs. The vMotion features are very good."
"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 has allowed us to be more resilient to infrastructure and hardware failure, reduced hardware costs, and decreased recovery time from failures."
"The most valuable features for us are DRS, VMotion, and, of course, some of the analytics that we were able to define to quantify our workloads and tell us how we are able to make our data center more efficient."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"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 should be made more user-friendly."
"The solution has a very small lifecycle."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"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."
"A few features of the product do not work as well as those in VMware."
"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."
"They must work on the price, as well as the technical support."
"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."
"We'd always like to see the price drop, but I realize that may not be realistic."
"It is not easy to upgrade VMware vSphere from an old version to a new version."
"Inability to get to a single hypervisor environment to support a container environment."
"The vSphere Client always feels slow, and/or like it doesn't keep up with what I'm trying to do. So I usually use the thick client most of the time."
"Monitoring information could always be improved."
"Security and patch-related items need improvement."
