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.

Extremely stable, good ROI, and scalable
The most valuable feature of our machines is their ability to replace faulty parts without causing any downtime. Our servers are equipped with advanced technology, making it possible to replace defective parts without having to bring down the servers. This is crucial, as any disruption to our services would result in inconvenience to our customers. Therefore, being able to service the machines and replace parts without causing any downtime is highly beneficial.

Quotes from Members

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

Pros

"The hardware itself is pleasant to work with. The management ability, particularly the out-of-band management, seems quite nice. The ecosystem tooling is also pleasant to work with. Additionally, Dell offers good support, and the servers are reliable."
"It is reliable. We have not faced any issues."
"Its approach to user security measures is valuable. We haven't experienced any major issues, and the solution has been working really well."
"VxRail has a smart and easy way to perform updates. The hypervisor on the other servers performs well according to the hypervisor level. The support is magnificent, and it's easier to administer the servers."
"This is a stable solution."
"Using PowerEdge rack servers has allowed us to use less space. Previously, we used the regular servers, but PowerEdge rack servers take up less space and are easier to handle."
"The active directory and file server are valuable features."
"When it comes to energy consumption they're also very good. They don't use power because they're power-hungry, but because we use them very hard."
"The most valuable feature of the solution stems from the fact that the hardware is really good and reliable."
"IBM Power Systems are secure and have fast processing."
"The performance is the solution's most valuable asset. It has one of the highest levels of performance I have ever seen. It's quite remarkable, in that sense."
"Additionally, the processing power is far superior, especially with the RSA feature for reliability, serviceability, and availability."
"The availability of a solution depends on the requirement of the customer. The most valuable feature is the virtualization. You can have this one system or you can use it for many. They were using almost 120 servers within that specific service."
"BM Power Systems get updated every two years and are scalable and stable."
"Power Systems' best features include its user-friendliness and self-checking/self-healing abilities."
"It scales a lot, you can just keep on adding frames, you can add on CPUs, you get capacity on demand, you can tune the machine very easily to handle different workloads."
 

Cons

"When interacting with customer support, it defaults to Arabic because of our region. However, most of the experts here are not familiar with Arabic. We would like English as an alternative language for easy interaction."
"Perhaps they could make it more power efficient. They're pretty good, but there's always room for improvement. Also, they could try to reduce heat generation."
"After purchasing the product, customers have not been getting the support that they need in the early stages of getting set up. They can provide customers a little bit more education as to what they get with certain warranty levels. The data is there if the customers dig, but a lot of times, the customers don't dig. Some of the other server models come out a little bit quicker than Dell. It would be good if Dell is quicker to market on new, larger drives when they become available. Sometimes, we do get hit on that against a couple of competitors. Dell vets them a little bit longer than like the super micros to keep their stability and quality level up, but they lose a little bit of ground to a super micro. It would be good if they can release features and models as soon and as fast as they can. It would help them to stay more competitive."
"While I wouldn't call it a problem, physically mounting the servers into the rails that come with the servers can be a challenge. They could be engineered to be a little bit easier to use. It's not that significant, we can manage it, but you need at least two people to do it together because they're a bit heavy."
"The specs for the benchmarks are very good, but the firmware and software are lacking. There are some issues with the Linux kernel and the long-term support (LTS) for some of the firmware's dependencies. It is causing the kernel to dump. The support for the Linux brands isn't optimal. We would like them to optimize the kernel drivers for benchmarks."
"There is room for improvement in certain aspects of the deployment process as it is a bit complex."
"I would like to see better IOPS, i.e. the disc speed. That is the main limitation for scaling up the number of users."
"PowerEdge is able to run the latest high-demand applications for our use case. They host our clusters and facilitate the building of environments."
"I think the cost should be cheaper."
"Sometimes, the availability of additional services can be a challenge. Certain IBM software takes time to deliver to the client. It can be slow."
"If you asked me what I'd like added, I'd say that it'd be nice if they ran GPUs, however, I know that's not the direction they're going. That said, I would appreciate it if they offered GPU support."
"IBM systems are old technologies. I couldn't renew and get to use IBM Power Systems, and it offers users very expensive support."
"Power Systems' price could always be lower."
"I know lab services does a lot of work but systems, if they could include some kind of lab services and bundling of services to get you to the greatest and latest feature at the already included cost"
"I think IBM needs a little more work on managing the overall environment with eliminating Systems Director."
"The solution is quite expensive."
 

Pricing and Cost Advice

"We weren't paying very much, but it was at the end of the lifecycle. We are now using the VxRail hyper-converged infrastructure, and the pricing was very similar for the same amount of power but with easier automation."
"The price is good for the quality of the Dell PowerEdge Rack Servers."
"The pricing is good compared to other products."
"It is expensive. The price needs to be more competitive. Additional licenses are required to enable some of the features for scalability."
"I have no issues with the pricing and licensing costs. They are fine."
"We have a strong agreement in place with our parent company, that typically ensures favorable pricing terms for us, although occasionally we may need to negotiate with Dell representatives for further discounts to provide competitive pricing to our customers."
"This solution is reasonably priced and licenses are easy to acquire."
"I don't know about the product's licensing part. Price-wise, it is an okay product. I believe that the cheaper the better, but I think that the product's price is okay."
"The solution's pricing is very, very high compared to other platforms."
"Its price is too high."
"There is a yearly licensing cost, and it's an expensive solution."
"The pricing is reasonable."
"The licensing costs are okay. With IBM Power Systems, it's inclusive, so you can differentiate the price of the hardware from the software itself."
"IBM Power Systems is very expensive."
"The price of the solution depends upon the configuration part of it. Based on what configuration you want to go for it, there is a range like IBM Power Systems POWER9 and IBM Power Systems Power10."
"When there is an error in the SAS drive of 10,000 RPM, my company buys support for 1,500 USD."

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.
