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
7.2
Dell PowerEdge R-Series servers offer cost savings, improved performance, and ROI benefits through reliability, ease of management, and energy efficiency.
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 users generally praise customer support for promptness and effectiveness, despite occasional delays and communication challenges.
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 enables seamless scalability and efficient workload management, supporting businesses with flexible expansion options.
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
8.1
The Dell PowerEdge R-Series is highly reliable and stable, with minimal downtime and rare hardware failures, ideal for enterprises.
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

Feedback for Dell PowerEdge R-Series highlights needs for improved performance, documentation, scalability, management, support, pricing, and energy efficiency.
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 offers competitive pricing, valued features, and flexible support options, making it a reliable investment for enterprises.
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 delivers scalability, reliability, and management tools, ideal for virtualization, AI applications, reducing downtime and costs.
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.

Handles workloads and diverse applications efficiently
We have a lot of VMs on Dell PowerEdge Rack Servers. On a single server, we have probably hosted 14 or 15 VMs. Out of these, 8 to 10 are continuously running, and four of them are backup VMs, so it can handle a good workload. For cybersecurity, it is only accessible on the intranet; it is not accessible through the web. We use it for local development purposes, and it is behind our firewall. Its security is strong. We handle a lot of test data for government and confidential customers. It is safe and strong locally. We have not experienced any security issues. Dell PowerEdge Rack Servers have helped to reduce unplanned production downtime if we need to replace a hard disk, instead of completely shutting a server, there is a hot swap feature. It is quite good in that aspect. Usually, for any activity, there is a downtime of about 30 minutes. It has saved a lot of time. We have tried AI workloads for a development environment for a government customer in Singapore. The servers are hosted in Singapore. It is an ML-based engine with AI. It is a government project where data is processed, and we run it on Dell PowerEdge Rack Servers. The benefit of running AI workloads on PowerEdge Servers is that it is easy to allocate memory. The application we are running is memory intensive. It is pretty easy to scale memory and storage.
Foluso  Jibowo - PeerSpot reviewer
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.
