IBM PowerVM vs. Oracle Virtualization

IBM PowerVM only is available on IBM POWER machines. It makes live much easier, compared to bare metal machines (OPAL) or machines with KVM. Personally I would not like to manage systems that don't have IBM PowerVM. The current line-up always includes IBM PowerVM (firmware built-in).

Well suited: development work as they provide a very nice free tier, datacenters in Latin America with very low ping, heavy loads for DB if you use Oracle DB Less appropriate: fast webservers as they use hard disks for several tiers, fast MySQL databases as the server is shared, auto-scaling functionality is not present.

• IBM PowerVM is used for virtualization on IBM Power series hardware to utilize the hardware resources more efficiently like micro partitioning for CPU, NPIV for fibre port...etc
• IBM PowerVM provides the feature of live partitioning mobility (LPM), which allows moving the running virtual machine from one hardware to another hardware without any disruption on a virtual machine.
• IBM Power VM provides the feature of Integrated virtual manager (IVM), which helps to manage the single IBM Power hardware. There is no need to purchase a separate hardware management console to manage the Power hardware. This works well for small organizations having small environments.

• Installation and setup of VM Server are pretty straight forward.
• Many different guest operating systems are supported.
• There can be up to 128 virtual machines per physical server.

• The ability to run Windows. Hardware architecture does not allow this, but it is a limiting factor.
• More performance monitoring and management could be built in.
• Sometimes is marketed and packaged in some rather unusual ways

The product works. It provides the proven environment to support IBM's primary operating systems that run on the IBM Power processing systems. This by extension includes the IBM various storage products that work within that environment. It has proven to be seamless as the environment has grown and as various new products and version updates have been added. As with most IBM products, the support is excellent.

I give it a solid ten. For what it is built for it delivers exactly what we need: predictable, controlled and reliable infrastructure. Even though it does have a learning curve, its not too steep to get to grips with and the reward and usability of the system is great. There is fine grained resource control ensuring optimal use of resources. Workload isolation and dynamic lpar reconfiguration ensures consistent and dependable results. Day to day management is handled with ease and confidence. If coupled with an automation solution, it becomes a highly usable platform at scale, allowing teams to standardize workloads

Our company utilizes VMware and PowerVM. VMware is very user friendly from an IT support view and makes supporting Windows OS easier. PowerVM is moving in that direction. PowerVM is better in that you can prioritize workloads across different VMs and be granular in your reservation of cores and virtual CPUs. PowerVM allows you to modify VM characteristics while the VM is up and running

• We are able to run several LPARs on one frame, which means we do not need to buy as many physical servers. That saves on floor space, power, and heating and cooling of the data center, among other things.
• Using LPM allows us to do maintenance on a frame without impacting the LPARs, giving us greater uptime.

• Forced me to manage another hard to manage virtual environment
