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.
"Red Hat is the most stable system."
"What they provide is way beyond the essential requirements of customers."
"It is a stable solution...It is a scalable solution."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"It is very stable."
"The solution is stable."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"The solution has a good licensing module."
"The product is very easy to install."
"We don't have any downtime because it was built right."
"Using vSphere we have virtualized over one thousand servers and this gave us management, cost and datacenter space advantages."
"vSphere has enabled an enterprise class virtualization environment with a central point of monitoring and management stretched over multiple datacenters (multi-site use), adding all the features of clustering for high-availability and failover, VM migration, and operations."
"The ability of a running VM to be quickly relocated to another hypervisor or launched at another site via replicated storage greatly reduces downtime."
"I like stability and the organization of the different functions into the I#M feature which is also quite useful, quite stable."
"The product offers good stability."
"The most valuable features are the seamless HA with vMotion and being able to run vCenters in HA mode."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"There is not any proper documentation on the site to reference."
"The solution has a very small lifecycle."
"A few features of the product do not work as well as those in VMware."
"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."
"The solution could use network virtualization."
"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."
"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."
"The only improvement that is needed that come to mind are improvements in the vRealize Automation and vRealize Operations management simplicity."
"The solution could be a bit more user-friendly."
"VMware has amped up how frequently they release new versions and that adds instability to a stable 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."
"Generally, the user interface needs to be improved for non-technical people."
"I would like to see better fault and performance reporting in the GUI."
"Integration with different platforms could be improved."
