We performed a comparison between Citrix Hypervisor, IBM PowerVM, and VMware vSphere based on real PeerSpot user reviews.
Find out what your peers are saying about Proxmox, VMware, Microsoft and others in Server Virtualization Software."The solution is extremely stable."
"Installing Hypervisor is really simple. It's the simplest setup I've ever done before. We used a team to deploy it, and it doesn't take much time, like two or three hours tops."
"The continued uptime of our virtual machines is good."
"Citrix is easy to use and is stable."
"The solution is easy to deploy. It's very easy to understand problems and read logs."
"The initial setup is easy."
"The ability to move a virtual machine while it is running is a big advantage."
"We find there are good central maintenance and central management panels."
"The feature that I like most is the versatility."
"You can increase resources with it automatically."
"The stability is the most valuable aspect of this solution. IBM is the most powerful and stable platform."
"Active Memory Sharing dynamically reallocates memory of running partitions based on changing workload demands. The memory for the pool is carved out from Physical memory and is made logical memory. The said memory is not available to be assigned to partitions as dedicated memory. A min, max and desired as well as weight is assigned to the memory of each lpar to help hypervisor make a decision in case a condition where priority is to be given to a certain lapr to use the memory form shared pool."
"The tool's performance is top-notch."
"The valuable feature of the solution is the technical aspects, focusing on elements like processor infinity."
"The most valuable feature is the flexibility in terms of managing the hardware resources such as RAM, CPU, and the network."
"Managing other operating systems is also straightforward with IBM PowerVM."
"Ease of support is one of the main features that we have with it. We're able to take Snapshots before doing updates to make it easy to roll back if something does happen to go wrong."
"The web console is the most valuable feature for me. Because no matter what happens with the server, I can still get to it with the web console."
"The most valuable feature of this solution is vMotion."
"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 scalability has been good."
"Valuable features include VHA, DRS, VMotion, and redundancy and failover; any DR situation."
"We've found the High Availability and flexibility to be important."
"I like that it's like a distributed rescheduler. You can move to and use VMotion as well. You can move the server and move the virtual machines around different physical servers. This makes it easier when it comes to redundancy."
"Live migration is something that can be improved."
"The solution is only in English. It would be ideal if it was in Portuguese."
"The solution should be more flexible and allow for greater customization."
"We'd like them to add more automation to the product."
"The product could be faster and licensing options could be improved."
"It needs improvement with the security features."
"Integration with other vendors and other applications could be improved."
"Overall, I can't think of a feature that is lacking. We've been pretty satisfied overall."
"I don't know whether this has been trialed already, but IBM should give us an alert when we reach seven or eight failovers so that we can automatically switch it to manual mode. That would be great because if we cross the 10-day licensing limit, we have to pay a hefty license cost to Oracle. If IBM could view that feature, it would be helpful in license compliance."
"The program has very limited solutions for the virtualization of containers"
"The cost of this solution is high."
"The interface is not user-friendly in places, so it could use some improvement."
"IBM PowerVM could improve the price because it is expensive."
"If it could actually virtualize the entire platform it might be better. If you're having more than one virtualization technology, maybe there's a way to actually have less - one technology to run the data center and maybe one special virtualization for power. If it integrated with other platforms more effectively it might be better."
"Any improvements that can be made in the interface will go a long way to helping us work better."
"This solution is lacking the ability to have servers act as a cluster, such as in VMware. IBM has come out with a feature similar to VMware's vCenter but it is not as mature. They need to add LPM shared-nothing feature, such as in vMotion."
"Its performance is an issue in version 6.5, but with the inclusion of HTML files in vSphere version 6.7, the experience is seamless. In version 6.7, VMware has included the HTML file protocol for the web browser or web console, which has changed the console's response and improved the performance. We are using the trial version of vRealize Operations. It would be nice if some of those capabilities could be included in future versions of vSphere, not as a part of vRealize Operations, but in vSphere itself. It can provide some kind of forecast about your resource consumption based on the actual workload and modeling or testing scenarios. It can give you some advice or tips for the future growth of your infrastructure."
"The technical support could improve by being a little faster."
"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."
"They should make it more efficient and stable."
"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."
"A fully **automatic** and lightweight Virtual Center. Another time this has a huge improvement in last releases. However, a more automatic and simple deployment is required."
"Both the price and the licensing fee are expensive, especially for our clients with a smaller workload."
"An improvement could be in terms of keeping up with the upgrades. The upgrades could be set in an automated way so that the newer features don't require you to manually update, or you get an option to update automatically. This would be a useful enhancement."
