Featured Reviews

Service Delivery Manager at a computer software company with 10,001+ employees
Virtualization has simplified partitioning and currently supports secure multi-tenant workloads
The ease of use of IBM PowerVM provides key benefits such as the installation being very easy, and the VIOS is really, really stable. IBM PowerVM is performing very well in supporting complex workloads. It's simple regarding the initial setup for IBM PowerVM. We always create two VIOS servers in IBM PowerVM to be compliant for security and to be compliant also for redundancy.
Toby Champion - PeerSpot reviewer

Ensures a robust, user-friendly virtualization platform with seamless VM management, efficient resource allocation and a strong community for support
Improvements are needed for the API. Currently, there are several features inaccessible through the API, necessitating the use of either the WebUI or the command line interface. While the command line interface suffices, it's apparent that efforts are underway to enhance this aspect. In future releases, one potential feature enhancement could be improved remote screen access, allowing users to connect to the screen of another machine more seamlessly. Additionally, integrating with Terraform or providing better support for Terraform workflows might be beneficial, as there seems to be some lacking in that area. There's a minor inconvenience where you have to switch the license file from the open-source community license to an enterprise license.
