PowerVM is a specialized hypervisor designed for IBM PowerSystems, which are risk-based systems. In a typical business or CIS systems landscape, you might use VMware or Hyper-V, but for IBM PowerSystems, PowerVM is the only available hypervisor.
In IBM systems, there's a unique use case. Unlike standard Intel-based servers or other platforms where all cores are readily available, in IBM systems, you must procure licenses for both the cores and the core activation.
PowerVM offers the additional functionality of moving these licenses along with the virtual machine (VM). This is where the mobility feature comes in – you can seamlessly move a VM between different PowerVM instances.
I use IBM PowerVM for our ERP, which runs group-wide systems. Several critical systems are running on top of PowerVM. The first benefit is workload consolidation—you can run a lot of workloads on a single server. Second, the platform is highly stable, leading to higher availability, scalability, and uptime. This has a direct, positive impact on the business.
