"The most valuable feature is the flexibility in terms of managing the hardware resources such as RAM, CPU, and the network."
"It's scalable. Whenever we buy another product other than hardware, it's easily integrated into the virtualization software that we download."
"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."
"A valuable feature of PowerVM is a feature that is used for higher availability plus stream for posting, which is very useful. There's a flash copy feature which we are using. PowerVM itself, I know, helps us to control and manage our Oracle licensing compliance, since it is our hardware partitioning. This is very important. If you use VMware, there will be a licensing issue. This PowerVM is a hardware partitioner, which is very important for license compliance. We are happy with this solution."
"The stability is the most valuable aspect of this solution. IBM is the most powerful and stable platform."
"The case fileserver on the web server is the most valuable feature."
"Technical support is great."
"The most valuable features in this solution are you do not get degradation in the performance like you could get in other solutions. There is a physical adapter that is better than a virtual one and you can assign adapters to a VM."
"That the product is free and still has all the features you expect is a huge benefit."
"There are many features included with Proxmox."
"The most valuable feature is the ease of deployment."
"The setup is very easy."
"Proxmox VE is simple to use and it is feature rich. The fact is that it performs,"
"The affordability of the solution is the product's most valuable aspect."
"We are happy with Proxmox VE. We use it as part of a cluster."
"The feature that I have found most valuable is that its storage container, LVM, and everything else work out of the box."
"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."
"A GUI version of VIOS would be a great plus for people moving from Intel-based hypervisors."
"I would like for IBM to be more focuses on the cloud."
"The performance should be improved."
"The interface is not user-friendly in places, so it could use some improvement."
"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."
"To make it a ten, I would like for them to add automation and configuration tools in order to help use the manager."
"The licensing could be better."
"The availability of the solution could be a bit better."
"Lacking in enterprise features."
"The initial setup has a pretty steep learning curve."
"The Windows drivers could be easier (unlike manually installing Ballon, QEMU and optionally SPICE, VIRTio, etc.)"
"Its performance and support can be improved. Currently, there is a cost for support."
"The product is still a little young so it is maturing, but new features are coming out all the time."
"The facility of deployment is an area that needs to improve."
"I can't speak to any improvements. It is not lacking features."
