IBM PowerVM and Nutanix AHV are competitors in the virtualization technology market. IBM PowerVM appears to have a strong advantage in stability and performance, while Nutanix AHV shines in affordability and manageability.
Features: IBM PowerVM offers robust stability, performance, and security features, particularly beneficial for Oracle workloads, through shared processor pools and active memory sharing for dynamic resource allocation. Nutanix AHV stands out for its simplicity and manageability, providing comprehensive virtualization capabilities, an intuitive management console, Prism, and cost-effectiveness as an open-source solution.
Room for Improvement: IBM PowerVM could benefit from improving its interface, enhancing cloud integration, and offering more flexible pricing. Users also desire better support for non-AIX/Linus systems. Nutanix AHV should expand system compatibility, improve automation and technical support, and develop a broader software ecosystem.
Ease of Deployment and Customer Service: Both solutions are typically used in on-premises settings, with Nutanix AHV also supporting hybrid environments. IBM PowerVM is known for excellent technical support, vital for enterprise applications, whereas Nutanix AHV's support is of average quality but offers flexible deployment options.
Pricing and ROI: IBM PowerVM involves higher initial costs due to hardware dependency but provides a good ROI for Oracle users by billing for allocated rather than total core usage. Nutanix AHV offers savings through inclusive licensing, making it an appealing low-cost alternative despite some initial expense concerns at larger scales.
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.
IBM offers excellent customer support.
IBM provides strong support.
IBM's technical support is outstanding, with seamless global coordination and prompt resolutions.
Their engineers are excellent and provide great supportability.
They provide prompt and quality responses.
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.
We can scale our systems easily without any downtime, making it a highly effective solution for dynamic environments.
Nutanix AHV Virtualization is very scalable; however, I might be underutilizing its capabilities.
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.
The solution is very stable.
Issues such as patch delays and the OVF format challenge affect its stability rating.
I would give the stability a seven out of ten at the moment, primarily due to the issues I've had with updates.
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.
This delay in patching creates risk, especially for government projects that require timely updates.
Using Lenovo hardware seems problematic with Nutanix AHV Virtualization, which demands careful consideration during updates.
These menus often show options like host, memory, and disk, however, they fail to provide insight into what's happening.
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.
This has been advantageous as it does not require additional licensing costs for the hypervisor, contributing to overall cost savings.
Other solutions like Citrix and VMware have seen a significant price increase, whereas Nutanix hasn't increased as dramatically.
The pricing was reasonable compared to other competitors, though the storage was expensive.
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.
It is easier to manage than VMware in some ways, providing a good level of interaction.
The technology behind the backups is very efficient, enabling a reliable virtual environment.
