We performed a comparison between IBM PowerVM and Nutanix Cloud Infrastructure (NCI) based on real PeerSpot user reviews.
Find out what your peers are saying about Proxmox, VMware, Microsoft and others in Server Virtualization Software."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."
"It is a stable solution with reliable performance."
"The most valuable feature of IBM PowerVM is the performance of the database workload."
"IBM PowerVM has the highest clock speed."
"PowerVM's most valuable features include swift optimisation and real-time migration."
"The tool's performance is top-notch."
"It is a complete solution."
"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 dashboard of Nutanix Acropolis AOS allows for simple management. The dashboard has all the information online about what's going on at any given time."
"The most valuable feature is Move, which allows you to migrate virtual machines from VM to AHV."
"It supports multi-cloud integration that includes AWS, Google, and Azure."
"The solution is well integrated with other vendors."
"Karbon is a must-have as it drastically simplifies the deployment of Kubernetes."
"I definitely find the reduced power consumption very valuable."
"We are suggesting Nutanix to the management because of scalability and time efficiency."
"Nutanix does a superb job with technical support."
"The performance should be improved."
"A GUI version of VIOS would be a great plus for people moving from Intel-based hypervisors."
"The hardware licensing model could be improved because the licensing model is a bit different from the standard hardware procured."
"The licensing could be better."
"SRM for site recovery is a feature that should be included."
"The product's pricing could be less expensive compared to other competitors."
"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."
"The cost of this solution is high."
"It's lacking in some features but overcompensating in others."
"I'm sure there are a lot of things that could be improved, but I'm actually very satisfied with this product. There may be some possibilities to move the virtual server dismounting points or to move the server from one group to another, but I can't think of any special improvements or update features."
"The One-Click Upgrade process could/should offer the ability to integrate with 3rd party drivers. For example, we use NVIDIA Grid graphics cards. It would be amazing if, during the One-Click Upgrade process, we could "slipstream" additional VIB drivers for ESXi into the upgrade process."
"I'd like it to be more API-based."
"The scalability of the solution had some issues because there were many VMs and the replication ran into some bottlenecks. It was an issue that was known to Nutanix and it was not disclosed to the customer."
"USB dongle-based licenses do not allow us to directly locate the USB ports on Nutanix."
"While their overall Nutanix Bible is good, they are lacking good descriptions for particular scenarios that might be helpful to many users."
"If they can simplify the software slightly for the installation, that would make all the difference."
