We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
"What I like about this solution, is that it is easy to configure."
"The feature that I like most is the versatility."
"It's in English, so its exceptional qualities make the control environment more flexible, easier, more stable, and easy to recover after issues."
"The stability is the most valuable aspect of this solution. IBM is the most powerful and stable platform."
"The most valuable feature is the flexibility in terms of managing the hardware resources such as RAM, CPU, and the network."
"The case fileserver on the web server is the most valuable feature."
"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."
"One of the most valuable features of this solution is the popularity of the OS."
"The solution is a great all-round product. The virtualization is especially good."
"Red Hat is the most stable system."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"The most valuable feature of this solution is the support portal."
"Stability and speed are the most valuable aspects."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"The solution makes migration easy."
"The program has very limited solutions for the virtualization of containers"
"Any improvements that can be made in the interface will go a long way to helping us work better."
"I would like for IBM to be more focuses on the cloud."
"To make it a ten, I would like for them to add automation and configuration tools in order to help use the manager."
"The interface is not user-friendly in places, so it could use some improvement."
"The performance should be improved."
"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."
"A GUI version of VIOS would be a great plus for people moving from Intel-based hypervisors."
"It would be better to have more patches, especially kernel-level updates, live and online so that we can keep the business up and running during this period."
"The solution could use network virtualization."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"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."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"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."
"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 price varies from case to case and you have to negotiate it for every project."
"The license cost is bundled with IBM Power Systems as it is limited to RISC-based IBM systems only."
"This is an open-source solution."
"I would say the price is acceptable."
"We are using the free version of Red Hat."
"I believe we pay on a yearly basis."
"We buy a license for commercial use, and we also use the free editions."
"We have to pay extra for vulnerability and fault tolerance."
"The solution does not require licencing but a subscription is necessary, which is very affordable."
Red Hat Enterprise Virtualization, or RHEV, is a leading open standard enterprise virtualization management solution. This solution supports virtualization of servers and desktops using the same infrastructure and a single easy-to-use interface.
Because RHEV is based on open standards, it is vendor-independent and a lot more cost effective and flexible than proprietary solutions.
IBM PowerVM is ranked 10th in Server Virtualization Software with 10 reviews while RHEV is ranked 8th in Server Virtualization Software with 16 reviews. IBM PowerVM is rated 9.0, while RHEV is rated 8.2. The top reviewer of IBM PowerVM writes "Secure with excellent stability and very good technical support". On the other hand, the top reviewer of RHEV writes "The versatility and compatability of this virtualization solution are marred by the lack of availability of local support". IBM PowerVM is most compared with VMware vSphere, Hyper-V, KVM, Proxmox VE and Oracle VM VirtualBox, whereas RHEV is most compared with KVM, VMware vSphere, Proxmox VE, Oracle VM and Hyper-V. See our IBM PowerVM vs. RHEV report.
