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
7.1
Dell PowerEdge R-Series delivers financial benefits through reliability, cost-effectiveness, seamless integration, and long lifecycle, enhancing productivity and morale.
Sentiment score
5.0
IBM Power Systems delivered high ROI through improved performance, cost efficiency, scalability, and enhanced processing capabilities with POWER8 upgrades.
By not having to worry about it, I would estimate we save two to four hours a week, depending on what's happening, such as if we need to spin up a new server, which would contribute to more time if done the old way.
In my immediate case for antenna analysis, Dell PowerEdge Rack Servers offer a reduction from days of computing to half a day or hours.
The value of uptime to us is critical.
The return on investment is very high.
 

Customer Service

Sentiment score
7.5
Dell PowerEdge R-Series support is valued for responsive service and expertise, despite minor delays and communication issues.
Sentiment score
1.0
IBM Power Systems support is valued for expertise and efficiency, with preference for higher-level assistance and effective local teams.
It has always been scheduled maintenance, which says a lot for a production environment, as we haven't had to call in a trouble ticket for the actual hardware during its entire run.
Typically, the contacts we have on-site are very knowledgeable, they come in within a day and usually have it fixed and taken care of if there are issues.
When we had a power supply failure out of the box, we called support, and they delivered the replacement within four hours as promised.
I try to get my support calls pre-routed to the US; I'd rather wait a couple of hours for support becoming available there than going to support somewhere in the Philippines or Indonesia.
Technical support from IBM is excellent.
 

Scalability Issues

Sentiment score
7.5
Dell PowerEdge R-Series is scalable and adaptable, supporting diverse workloads with modular upgrades for growing business needs.
Sentiment score
6.0
IBM Power Systems offers scalable solutions praised for flexibility, supporting all business sizes with seamless transitions and dynamic resource allocation.
The scalability of Dell PowerEdge Rack Servers is excellent.
Any outages or blackouts are limited to particular servers, not affecting the whole chassis or enclosures.
We bought our product with scaling involved, and we've been scaling it up anytime we've needed more storage.
IBM Power Systems is a completely scalable solution.
 

Stability Issues

Sentiment score
7.9
Dell PowerEdge R-Series offers reliable, robust performance with minimal downtime and efficient operation under demanding workloads, ensuring user satisfaction.
Sentiment score
3.5
IBM Power Systems are highly reliable and stable, with minimal downtime, excellent performance, security, and strong support.
Over four years, we've had less than 1 percent downtime.
There is a feature to update the server while it is running, so there is no need to restart.
We have truly not had any downtime on the infrastructure at all.
IBM just released IBM Power11 last month with significant improvements, eliminating the need for downtime in your environment.
 

Room For Improvement

Dell PowerEdge R-Series improvements include memory speed, management, scalability, documentation, integration, security, pricing, support, and noise reduction.
Suggestions for IBM Power Systems include clearer licensing, faster processing, better cloud integration, improved interfaces, scalability, and enhanced marketing efforts.
We need to know about any upcoming updates so that we can plan accordingly.
The beneficial aspect of that feature was that we could skip the PowerStore and just have the Dell PowerEdge Rack Servers alone, as they also served as storage, which helped us save money.
This forces you to go up to a larger server to get the desired processor, which increases the cost.
IBM gives customers peace of mind.
 

Setup Cost

Dell PowerEdge R-Series pricing is seen as competitive and valuable for its reliability, support, and transparent pricing.
IBM Power Systems are costly but offer high performance and reliability, appealing to larger organizations despite complex configurations.
They have been stable and running for years without performance downtime or significant disc failures.
Some customers find it cheaper due to contractual agreements, while others find it expensive, especially when scaling up.
The software associated with servers, like VMware subscription licenses, drives costs.
Initially when sizing it, people perceive IBM Power Systems as quite expensive.
 

Valuable Features

Dell PowerEdge R-Series excels in scalability, reliability, security, and performance, offering efficient remote management and versatile configurations for businesses.
IBM Power Systems offer robust performance, scalability, and security, supporting extensive workloads and reducing ownership costs efficiently.
They keep running for at least five to seven years without any issues.
With PowerEdge Servers, I don't need a one-to-one ratio redundancy, which leads to about eighty percent downtime reduction.
One of the valuable features is Active Directory, which helps in managing the network.
For over 13 years, IBM systems have been the most secure in the industry.

Featured Reviews

Ravi Ramananda - PeerSpot reviewer
Offers unmatched security, stability, and uptime
Based on my experience, one area where Dell could improve the PowerEdge R-Series servers is in the disk bus controllers. There is a need for advancements in this area from a hardware perspective. While PowerEdge has several AI-enabled models and is making strides in technology, I believe that the hard disk controllers need to be more effective compared to competitors like Lenovo and HPE. Currently, even when using SSDs or SaaS disk models in my Dell PowerEdge R-Series servers, the throughput is roughly 10%-15% lower compared to similar offerings from HPE and Lenovo. While this doesn't have a major impact on my business, it is worth noting since Dell has a strong position in Gartner ratings. Overall, the hardware quality is good, but I frequently encounter errors that are not hardware-related; they're mainly cyclic errors where the server struggles to process data as quickly as other manufacturers' controllers. Despite this, I am completely satisfied with the functionality of the Dell PowerEdge R-Series. Flexibility is a debatable topic, and I would rate it about a six out of ten. When it comes to flexibility, we do need to account for downtime if we want to extend or make changes. There are very few hot-pluggable devices in Dell servers compared to others, making online plug-and-play opportunities limited. So, I would rate flexibility as a six rather than a five.

Has empowered enterprises with secure and cost-effective solutions
When discussing disadvantages, I do not see many areas for improvement because we have received good testimonies from every client. IBM gives customers peace of mind. One challenge, which I would not really call a challenge, is that initially people have the notion that IBM Power Systems is quite expensive. However, IBM does not lose deals based on price. This is a message we need to keep communicating to people who feel that IBM is on the high side in terms of cost. We encourage them to have a discussion with us about their total cost of ownership over three or five years. There is a notion in the market that IBM is expensive, which is false. However, once we engage and show them their return on investments and their total cost of ownership savings, they tend to embrace IBM.

IBM Power Systems vs Dell PowerEdge Rack Server IBM Power Systems is a RISC (Reduced Instruction Set Computer) system that contains 8 threads or over per core. This processor performs super-fast due to the RISC algorithm technology than any other Intel-based hardware (e.g., Dell, HPE, Cisco).  In Intel, there are only 2 or 4 threads per core and it performs according to CISC (Complex Instruction Set Computer). IBM Power system is a sustainable, reliable and obviously costly solution compared to any other Intel-based solution.  Generally, IBM Power system is used in mission-critical systems.

IBM Power comes with virtualization integrated (PowerVM), highly optimized (practically with no performance impact) - no need for VMWare, HyperV etc.  For database it is the recomended platform - even is Hana, Oracle (best combination with AIX) or DB2 (DB2 for me is the most autonomous database that you can have).  The downside of IBM Power could be the lack of support for Windows and the initial cost.
