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
7.8
Citrix XenServer offers cost savings and enhanced efficiency through virtualization, justifying the investment despite higher initial costs.
Sentiment score
7.7
PowerVM saves costs by charging for allocated cores, proving more cost-effective and reliable than physical servers over five years.
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.
 

Customer Service

Sentiment score
4.8
Citrix XenServer's customer service varies in effectiveness, with challenges in response times and support access, especially for complex issues.
Sentiment score
7.8
IBM PowerVM's support is praised for responsiveness and expertise, though challenges arise without subscriptions; stability minimizes service need.
With valid licenses, we can access hotfixes, service packs, knowledge base, self-help tools, diagnostics, downloads, live chat, and phone support.
They do not provide adequate support for midsize businesses.
There appear to be very few engineers at Citrix who understand the problems.
IBM provides strong support.
IBM offers excellent customer support.
IBM's technical support is outstanding, with seamless global coordination and prompt resolutions.
 

Scalability Issues

Sentiment score
7.9
Citrix XenServer offers effective scalability and integration, appreciated for its ease, cost-effectiveness, and support for enterprise growth.
Sentiment score
8.1
IBM PowerVM excels in scalability and flexibility, efficiently managing resources and users for both small and large enterprises.
Familiarity with Linux can enhance its performance and usability.
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.
 

Stability Issues

Sentiment score
7.7
Citrix XenServer is reliable for SMBs, supports high uptimes, but may occasionally face minor issues, especially with backups.
Sentiment score
8.5
IBM PowerVM is praised for exceptional stability and uptime, outperforming competitors like SPARC, Nutanix, and VMware in reliability.
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.
 

Room For Improvement

Citrix XenServer needs better backup, integration, management, stability, compatibility, affordability, technical support, community engagement, and marketing.
IBM PowerVM needs usability, pricing, automation, integration improvements, and a GUI to better compete and enhance user experience.
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 can implement high availability and live migration with pools, along with security and backup to enable role-based access control for safer management.
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.
 

Setup Cost

Citrix XenServer is a cost-effective alternative to VMware, though pricing can be complex and varies with needs.
IBM PowerVM pricing is high but offers reliability, flexible licensing, and potential TCO savings despite cheaper alternatives.
It is cheaper compared to its competitors.
Organizations save substantial money because competing solutions, such as VMware, cost double or triple.
The pricing and licensing policy of Citrix XenServer is not transparent and quite confusing.
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.
 

Valuable Features

Citrix XenServer offers virtualization, ease of use, scalability, and strong support, ideal for small to medium businesses.
IBM PowerVM offers stability, flexibility, and high availability with robust virtualization, cloud integration, and optimized workloads for Oracle and SAP HANA.
The most valuable feature is transferring and sharing applications that allow users to move files between devices, including smartphones, tablets, and computers without needing USB cables, internet connections, or data usage.
It provides secure access to applications and resources, which is crucial for us and our clients.
It is user-friendly and easy to deploy, making it an attractive option.
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.

Cost efficiency enables significant savings but improvement in support and backup integration is needed for enhanced reliability
In the past, we utilized the live migration feature in Citrix XenServer, but not in this project. This is a new, fresh deployment, so there is no live migration. The support of heterogeneous resource pool in Citrix XenServer depends on the deployment and customer requirements. If a customer requires heterogeneous deployment, we accommodate that. Generally, Citrix XenServer goes in straightforward vanilla deployment because it is majorly used for Citrix farms. Very few customers use it for other products or applications. Intelligent performance optimization is available in this product, but very few customers use it, and those who do aren't using it extensively. I cannot comment extensively on this feature at present.
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.
