IBM PowerVM and Citrix XenServer compete in the virtualization category. PowerVM seems to have the upper hand due to its advanced features like Live Partition Mobility and its strong reputation for stability and security.
Features: IBM PowerVM offers advanced capabilities such as Active Memory Sharing, Live Partition Mobility, and high security to efficiently manage resources and ensure compliance. Citrix XenServer, on the other hand, boasts ease of setup, management with Windows-based applications, and real-time performance monitoring, accommodating Windows and Linux OS compatibility.
Room for Improvement: IBM PowerVM is often criticized for its high cost and limited OS compatibility, which restricts it to IBM-approved systems. Users also call for improved cloud integration and a more user-friendly interface. Citrix XenServer needs better management tools, enhanced Linux support, and integration with third-party solutions. The free version's limitations often push users towards its paid support for full functionality.
Ease of Deployment and Customer Service: IBM PowerVM is known for its effective technical support, characterized by responsive assistance, though some suggest improvements in complex cases. Citrix XenServer offers easy deployment, backed by average customer service and adequate technical support, which benefits from a broad user community.
Pricing and ROI: IBM PowerVM is priced at a premium, but users find its comprehensive licensing and reliability worth the investment, although cost remains a concern. Citrix XenServer's free edition is appreciated for its cost-effectiveness with available paid options. Despite significant cost savings compared to VMware, high licensing costs can deter budget-conscious buyers.
My clients generally maintain their Citrix infrastructure without shifting, suggesting stability and reliable operation as Citrix XenServer is fully established.
The return on investment is substantial, though other platforms may offer a better ROI, primarily due to lower costs involved in setup and maintenance.
If calculated over a five-year period, IBM PowerVM is 30 to 40% more cost-effective than physical servers despite initial costs seeming high.
They do not provide adequate support for midsize businesses.
Customer support can be complex and slow, especially when dealing with Unicom.
Since being acquired, Citrix's customer service has experienced delays in response time.
IBM offers excellent customer support.
IBM provides strong support.

An IBM server can handle up to sixty-four terabytes of RAM.
The product is scalable due to PowerVM's virtualization features, such as shared processor functionality and partition mobility.
I think IBM PowerVM uses a 'pay as you grow' model, allowing customers to scale their resources as needed.
The stability of IBM PowerVM is exceptional, as industry reports have named IBM Power and Z as the most stable platforms globally for 15 consecutive years.
Our clients in India using Power Servers have been running their servers for the last four to five years without any reboot.
The product operates reliably, and following IBM’s best practices ensures robust stability.
Although the product is technically competitive, it is not widely known or used due to poor marketing.
Citrix needs to improve the hypervisor, specifically in security and performance.
We have a strong relationship with IBM, which aids decision-making in transitioning clients from mainframe to other platforms.
From a product perspective, I would like to see faster certification of open-source products on IBM Power Systems.
PowerVM should integrate some capabilities of VMware vCenter to improve its management features.
It is cheaper compared to its competitors.
The pricing is considered not expensive.
The pricing and licensing policy of Citrix XenServer is not transparent and quite confusing.
PowerVM itself is free with the purchase of an IBM server.
They have introduced a subscription-based model for some systems, creating a more cost-effective solution for customers.
Pricing is a concern in Argentina due to the higher cost of mainframe solutions.
It is user-friendly and easy to deploy, making it an attractive option.
It provides secure access to applications and resources, which is crucial for us and our clients.
Features like partition mobility enhance the machine's capabilities, making it an ideal tool for virtual environments with reliability, availability, and serviceability.
IBM PowerVM supports multiple operating systems such as IBM i, AIX, and Linux, allowing users to run various applications seamlessly in a cloud environment.
It supports specific workloads, like Oracle and SAP HANA, much better due to its shared processor pool feature which reduces licensing costs.
