Scalability Issues

Sentiment score
8.1
IBM PowerVM excels in scalability and flexibility, efficiently managing resources and users for both small and large enterprises.
Sentiment score
7.9
Nutanix Cloud Infrastructure is scalable, user-friendly, and flexible, though some note limited storage per node.
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 scalability of Nutanix Cloud Infrastructure (NCI) deserves an eight out of ten rating, as there is no solution that is 100% efficient and there is always room for improvement.
 

Stability Issues

Sentiment score
8.5
IBM PowerVM is praised for exceptional stability and uptime, outperforming competitors like SPARC, Nutanix, and VMware in reliability.
Sentiment score
8.2
Nutanix Cloud Infrastructure offers high stability and reliability, enabling seamless scalability and maintenance with minimal downtime.
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.
Compared to VM, we find it most stable.
Regarding stability, I would rate Nutanix Cloud Infrastructure (NCI) a seven out of ten.
 

Room For Improvement

IBM PowerVM needs usability, pricing, automation, integration improvements, and a GUI to better compete and enhance user experience.
Nutanix Cloud Infrastructure needs improvements in cost, performance, integration, backup solutions, and simplifying licensing, installation, and GUI.
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.
We hope Nutanix can integrate inside our current license module.
I would suggest that Nutanix Cloud Infrastructure (NCI) should develop their own P2V (physical to VM) tools instead of requiring users to rely on third-party solutions.
 

Setup Cost

IBM PowerVM pricing is high but offers reliability, flexible licensing, and potential TCO savings despite cheaper alternatives.
Nutanix Cloud Infrastructure offers competitive pricing with favorable total cost of ownership, valued for its integrated solutions and features.
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 costs more compared to VMware due to different licensing areas.
The pricing is renewed every year, at almost $100,000 per year.
 

Valuable Features

IBM PowerVM offers stability, flexibility, and high availability with robust virtualization, cloud integration, and optimized workloads for Oracle and SAP HANA.
Nutanix Cloud Infrastructure provides high-performance storage, easy management, flexibility, scalability, automation, and robust disaster recovery with redundancy.
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.
When technology development or devops teams request server provisioning, the setup time has been reduced from hours to less than 20 minutes.
The replication method between Nutanix clusters is a valuable feature.

Offers mobility and you can seamlessly move a VM between different PowerVM instances
PowerVM is likely one of the most stable hypervisors available, albeit highly specialized. However, it is solely command-line based. When someone manages virtualization as a whole, they typically expect a graphical user interface (GUI) for configurations. This is the case for Hyper-V, XenServer, and VMware. But with PowerVM, you need to understand and memorize commands to operate the hypervisor. I believe PowerVM should have a GUI; that would be a significant improvement.

Offers a unified platform, reduces downtime, and simple updates
Nutanix offers a unified platform for managing databases, virtual machines, and applications. This simplifies management by consolidating everything into a single interface. While Nutanix may have a higher upfront cost compared to other hypervisors, it can significantly reduce the resources needed for infrastructure management. With our previous hypervisor, we needed nearly ten IT personnel. Nutanix has allowed us to streamline our team to just three members. We use a combination of database technologies, including SQL databases and web servers such as IIS, BHP, and NGINX. Nutanix features helped our organization reduce downtime. I don't recall the last time we had downtime related to Nutanix because it is such a stable product. Nutanix, a reliable product, helps us streamline our processes, which in turn improves company revenue. We began to see the benefits after two years, with a 40 percent reduction in operational costs. We migrated 200 servers from AWS to Nutanix. Nutanix may not consolidate applications, but it helps us run them more efficiently on its platform. Updating is simple with one click. I would rate the updating processes 10 out of 10. Adding compute and storage on demand is not difficult. However, we need to factor in the existing and new firmware and software requirements.

Nutanix vs. VMware EVO:RAIL vs. FlexPod
Originally posted at www.storagegaga.com/dont-get-too-drunk-on-hyper-converged/ I hate the fact that I am bursting the big bubble brewing about Hyper Convergence (HC). I urge all to look past the hot air and hype frenzy that are going on, because in the end, the HC platforms have to be aligned…
