Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.7
PowerVM saves costs by charging for allocated cores, proving more cost-effective and reliable than physical servers over five years.
Sentiment score
7.5
Organizations anticipate value from VMware vSphere Foundation through enhanced scalability, manageability, optimization, and flexibility, despite initial ROI not being evident.
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.
In an environment where the infrastructure has to be up for monitoring and controlling physical infrastructure like water plants, it has absolutely returned on its investment.
There is flexibility and interoperability with multi-mode architectures that accommodate both on-prem and cloud realities.
Server consolidation is one return on investment where we can use one server for multiple workloads.
 

Customer Service

Sentiment score
7.8
IBM PowerVM's support is praised for responsiveness and expertise, though challenges arise without subscriptions; stability minimizes service need.
Sentiment score
6.8
Customers previously praised VMware, but Broadcom's management leads to mixed reviews, highlighting response time and regional support.
IBM provides strong support.
IBM offers excellent customer support.
IBM's technical support is outstanding, with seamless global coordination and prompt resolutions.
There is nonstop support available around the world, which allows issues to be resolved continuously without interruption, regardless of whether the problem occurs in the USA, India, or another location.
Now, with Broadcom's management, I would rate it a three out of ten.
Most of the time, VMware operates smoothly without requiring support.
 

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
8.6
VMware vSphere Foundation is highly scalable, easy to integrate, and supports varied environments, though some users seek more exploration.
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 return on investment is high because we can maximize the use of one server for multiple workloads.
It's straightforward to procure additional licenses, install them on the host and add them to the same cluster.
You can simply add more hosts to your VMware stack seamlessly, scaling up vertically or horizontally.
 

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
8.4
VMware vSphere Foundation is highly rated for stability and requires minimal management but frequent security updates are necessary.
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.
Stability is optimal.
Frequent updates are required due to constant security challenges and attacks.
It is a standard tool and is considered very stable.
 

Room For Improvement

IBM PowerVM needs usability, pricing, automation, integration improvements, and a GUI to better compete and enhance user experience.
VMware vSphere Foundation struggles with pricing, licensing, support challenges, impacting user experience, especially post-Broadcom acquisition in Latin America.
We have a strong relationship with IBM, which aids decision-making in transitioning clients from mainframe to other platforms.
PowerVM should integrate some capabilities of VMware vCenter to improve its management features.
From a product perspective, I would like to see faster certification of open-source products on IBM Power Systems.
I highly recommend that continuous support for perpetual licenses be provided.
VMware needs to improve cost efficiency, especially in Pakistan, as customers often seek more affordable solutions.
Recently, VMware shifted its licensing models, and they should streamline it.
 

Setup Cost

IBM PowerVM pricing is high but offers reliability, flexible licensing, and potential TCO savings despite cheaper alternatives.
VMware vSphere Foundation's high costs and limited support post-Broadcom merger frustrate enterprise buyers, despite its reliable performance.
Pricing is a concern in Argentina due to the higher cost of mainframe solutions.
PowerVM itself is free with the purchase of an IBM server.
While initially costly, the ROI over five years proves IBM PowerVM is cost-effective, resulting in a 30 to 40% reduction in costs compared to a physical setup.
It's expensive, however, the stability it offers is optimal.
In Brazil, we are increasingly using open-source alternatives like Proxmox due to their lower prices in comparison.
During one project, the price doubled or even tripled before implementation, causing issues with clients.
 

Valuable Features

IBM PowerVM offers stability, flexibility, and high availability with robust virtualization, cloud integration, and optimized workloads for Oracle and SAP HANA.
VMware vSphere Foundation enhances scalability, reliability, and management, offering tools for efficient resource use, cloud integration, and uptime.
Features like partition mobility enhance the machine's capabilities, making it an ideal tool for virtual environments with reliability, availability, and serviceability.
PowerVM excels in efficiently managing all systems and environments, including development, UI, and production.
It supports specific workloads, like Oracle and SAP HANA, much better due to its shared processor pool feature which reduces licensing costs.
vSphere Foundation is valuable due to its scalability, reliability, and ease of management.
VMware provides the tools needed to move environments between private and public clouds seamlessly.
The virtual stack of vCenter, its distributed resources system, high availability engines, and the ability to move VM workloads from one host to another are outstanding.

Desianto Abdillah - PeerSpot reviewer
A practical virtualization environment with a Live Partition Mobility feature that help us handle virtual adapters effectively
The practicality of IBM PowerVM is a crucial feature, especially with the help of HMC (Hardware Management Console). The Live Partition Mobility help us handle virtual adapters effectively when we need to upgrade firmware or the system, and LPM helps us transfer workloads with minimal downtime. This feature ensures that our systems remain online even during maintenance, significantly minimizing any potential disruptions.
ErmiasGirma - PeerSpot reviewer
Virtualization enhances management and utilization in enterprise environments
In the past, we faced challenges with VMware's transition to Broadcom, which caused a lot of frustration. Issues like not being able to upgrade to version eight without support and the end-of-life of perpetual licenses were concerning. Pricing fluctuation and increased licensing costs were also significant challenges. I highly recommend that continuous support for perpetual licenses be provided.
